(BMcD), under contract with the Oklahoma Department of Central Services (DCS) Construction and Properties Division (DCS Project #12069C / PO# 2929014842) on behalf of the Oklahoma Department of Environmental Quality (ODEQ), is conducting a remedial design (RD) for the Tulsa Fuel and Manufacturing site in Collinsville, Oklahoma (TFM Site). The RD is 100 percent federally funded through a Cooperative Agreement (CA) between the ODEQ and the United Stated Environmental Protection Agency (USEPA). A description of the RD project is included in Section 1 of the Remedial Design Work Plan, Tulsa Fuel and Manufacturing, Collinsville, Oklahoma (RD Work Plan) (BMcD, 2012e). 1.1 OBJECTIVES This Remedial Design Data Evaluation Report has been prepared by BMcD, as required in the Consultant Statement of Work for the Remedial Design for the Tulsa Fuel and Manufacturing Superfund Site (ODEQ, 2011), to compile and tabulate soil, sediment, waste, and geological data obtained during the RD field investigation activities. Data were compared to applicable remedial action objectives (RAOs) to determine the extent of materials requiring remediation and a preliminary estimate of the volume of the materials requiring placement in the consolidation cell and/or potential stabilization during the remedial action. In addition, an evaluation of soils at the TFM Site for potential use as borrow material for the consolidation cells was performed, and data collected to support the requirements of Oklahoma Administrative Code (OAC) Title 252. Department of Environmental Quality, Chapter 515. Management of Solid Waste, Subchapter 7. Subsurface Investigation (OAC 252:515-7) for the consolidation cell are provided. This Data Evaluation Report provides information obtained during the RD field investigation activities conducted from March 1 through July 13, 2012, including field observations, sample collection, laboratory analytical results, and data screening. RD field activities included: site reconnaissance, including topographic survey and visual waste survey sampling of on-site surface and subsurface soil to verify the extent and volume of soil and waste material requiring remediation sampling of off-site (south of the Strip Mine Pit) surface and subsurface soil to verify the volume of soil and waste material requiring remediation sampling of on-site subsurface soil to evaluate potential on-site borrow sources for cap material for the consolidation cell Remedial Design Data Evaluation Report Introduction Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_01_Final.doc 1-2 03/04/2013 soil profiling and monitoring well installation to collect piezometric elevation measurements to meet permit requirements for the consolidation cell sampling of on-site sediment to determine vertical extent of sediment contamination sampling of on-site surface water for characterization of discharge purposes recycling of waste tires on-site incorporation of remedial investigation (RI) investigation-derived waste (IDW) into defined waste area ecological site reconnaissance ambient air monitoring and personal exposure monitoring 1.2 DOCUMENT ORGANIZATION This Remedial Design Data Evaluation Report presents a summary of RD investigation activities and sample results.

The TFM Site is located in the NE1/4 SE1/4 NE1/4 Section 31 and SW1/4 NW1/4 Section 32 Township 22 North Range 14 East in Tulsa County, Oklahoma, and has the coordinates of 36° 20’ 45.59” north latitude and 95° 50’ 51.28” west longitude. As shown on Figure 1-1, the area within the TFM Site boundary consists of approximately 60.7 acres and is bounded by “Old” U.S. Highway 169 and the Atchinson Topeka Santa Fe railroad tracks (currently operated by WATCO) to the east; a flooded strip mine pit from a former coal mining operation to the south; and, agricultural and residential lots to the north and west (Oklahoma State Department of Health [OSDH], 1992 and ODEQ, 2011). Additionally, property owned by the Faith Assembly Church property bounds the TFM Site to the north. The Collinsville Smelter, which is another former zinc smelter, is located approximately one-fourth mile to the east-northeast of the TFM Site (Figure 1-1) on 220 acres of property formerly owned by the Bartelsville Zinc Company, and it is undergoing investigation and remediation (ODEQ, 2011). The majority of the facility structures have been demolished. Previous studies have indicated that portions of the TFM Site are covered with waste consisting of broken retorts and condensers, slag, building debris, ash, bricks, and other materials from the former smelting operations (BMcD, 2007). This waste area is located to the south of the access road/driveway (Figures 1-2 and 1-3). During the RI, waste materials were visually observed at the surface or within borings or trenches across approximately 25 acres. In addition, the access road/driveway was observed to contain waste materials. The waste varies in thickness from 2-feet (ft) to greater than 6-ft. The waste piles are not covered, and run-off is Remedial Design Data Evaluation Report Introduction Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_01_Final.doc 1-4 03/04/2013 uncontrolled. The waste borders the southern strip mine pit, and portions of the waste have collapsed into the impoundment. This impoundment, which receives surface water runoff from the TFM Site, is reportedly a local fishery and flows into an intermittent drainage ditch that borders on the eastern edge of the waste (BMcD, 2007). An intermittent stream originates in this area and flows approximately three quarter of a mile before draining into Blackjack Creek, which is located east of the TFM Site (Figures 1-1 and 1-2). Three intermittent ponds, which are assumed to be remnants of a 2-million gallon reservoir, are located north of the former smelter operations area (BMcD, 2007). In addition, two smaller ephemeral ponds are located on the TFM Site (Figure 1-3). The area north of the access road/driveway is vegetated with grasses (Figure 1-3). With the exception of the southern boundary at the strip mine pit, a 6-ft chain link fence surrounds the TFM Site. A residence (Figures 1-2 and 1-3), which was occupied from 1935 through February 2002, was located on the site near the former office building (paymaster hut). The on-site residence was destroyed by a fire and is currently unoccupied. The residence has a water well that was used in the past for drinking water, but it is no longer in use. No other residential structures are located on the Site; however, a garage and a few storage sheds remain adjacent to the former residence (ODEQ, 2011). A cistern is located just north of the mid-site ravine intermittent drainage that travels west to east across the former operation area of the TFM Site (Figure 1-3). Waste material at the TFM Site has impacted soil, sediment, and surface water. Ground water at the TFM Site has not been impacted (ODEQ, 2011). 1.4 SITE HISTORY During World War I zinc was in great demand. It was used to galvanize armaments to prevent rust. A zinc smelter and lead roaster were at the TFM Site from 1914 through 1925. Historically, the smelter was known as the Prime Western Smelter. The TFM Site was also misnamed as the Acme Brick Strip Mines site, since it was immediately adjacent to a strip mine on its southern boundary. Use of the land prior to the smelting operation is unknown (OSDH, 1992). The smelting operation utilized nine furnaces, approximately 150 ft in length by 60 ft wide, which were believed to be fueled by nearby natural gas wells. Other main structures of the smelter included a mechanical kiln building approximately 240 ft by 80 ft in size, a condenser room approximately 75 ft by 50 ft in size, and a laboratory (See Figure 1-2). A 2-million gallon capacity reservoir was used in conjunction with the condenser room during smelting operations. In addition, large amounts of ore were stored on the TFM Site in the area northeast of the waste piles (Figure 1-2). Little is known about waste management at the smelter during its operation. Due to the time period in which the smelter operated, it is unlikely that air emission control devices were used (ODEQ, 1994 and OSDH, 1992). Remedial Design Data Evaluation Report Introduction Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_01_Final.doc 1-5 03/04/2013 Strip mining occurred in the surrounding area. Immediately south of the TFM Site was a strip mining operation approximately 40 acres in size, which was known as the Acme Brick Strip Mine (OSDH, 1992). A water-filled surface impoundment (i.e., Strip Mine Pit), which acts as a southern boundary to the TFM Site, is currently associated with the former strip mine. It has been reported that this impoundment serves as a local fishery. Another strip mine area operated just east of the TFM Site, and one was located in northeast Collinsville (Figure 1-1). The Collinsville Smelter, which is being evaluated through ODEQ’s Voluntary Cleanup Program, is located approximately one quarter of a mile to the east-northeast of the TFM Site (Figure 1-1). The Bartelsville Zinc Company owned and operated this zinc smelter between 1911 and 1918. The Bartelsville Zinc Company owned 220 acres of land surrounding the Collinsville Smelter, and an area of approximately 40 acres has been designated as the location where the primary smelter activities occurred. In 1987, the Collinsville Smelter was reclaimed and regraded by the Oklahoma Conservation Commission (OCC) in conjunction with reclamation of the adjacent coal strip mine (Exponent, 2001). The majority of the structures have been demolished, but several foundations and building footings remain on the TFM Site. On September 28, 1928, the 120-foot tall and 11-foot diameter smokestack was imploded. A residence (Figure 1-2), which was occupied from 1935 through February 2002, was located on the TFM Site near the former office building (paymaster hut). The on-site residence was destroyed by a fire and is currently unoccupied. No other residential structures are located on the TFM Site; however, a garage and a few storage sheds remain in place adjacent to the former residence. Although the TFM Site is fenced on all sides except for the Strip Mine Pit, there is evidence of trespassing. There is abundant evidence of fishing and hunting activity around the ponds on the TFM Site, and fishing in the ponds has been reported on several occasions. In addition, individuals have been observed picking blackberries along the eastern fenced boundary and evidence of off-road vehicle traffic is present. The area in the vicinity of the on-site residence, including the garage and storage sheds and along the access road/driveway, has become a dumping area. Broken appliances, used exercise equipment, tires, junked cars, and assorted trash/debris were observed during the RD field activities. * * * * * Remedial Design Data Evaluation Report Introduction to Data Presentation and Evaluation Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_02_Final.doc 2-1 03/04/2013 2.0 INTRODUCTION TO DATA PRESENTATION AND EVALUATION 2.1 FINAL CLEANUP LEVELS RAOs are the cleanup objectives for protection of human health and the environment. ODEQ and USEPA developed RAOs for TFM Site soil, sediment, surface water, and waste material. Cleanup levels were established for both residential and nonresidential soil. These site-specific cleanup levels are the desired endpoint concentrations that provide adequate protection of human health and the environment for each exposure route. Although the TFM Site is currently unused vacant land, it is reasonable that future land use may be zoned residential based on development interest in the general area. Cleanup to residential levels will result in partial unlimited use, unrestricted exposure, and will be protective for human and terrestrial ecological receptors. The cleanup levels for the TFM Site are presented on Table 2- 1. Materials such as broken retorts and condensers, slag, and other smelter related materials represent a primary source material at the Site (USEPA, 2008). Although the contaminated soils present at the TFM Site represent a source material, they are not characterized as a “principal threat waste” because the resulting soil contamination associated with this smelter material can be reliably contained (USEPA, 2008). For purposes of the RD, waste materials that cannot be sampled can be identified by a visual standard. As such, any visible waste material associated with the historical smelter operation will be addressed during the remedial action (RA) for the TFM Site. A summary of the RAOs for the TFM Site are provided in the following paragraphs: On-Site Soil and Waste Materials: Protect human health by preventing direct contact, through the ingestion or inhalation exposure pathways with arsenic, cadmium, and lead contaminated on-site soil and waste material by reducing arsenic, cadmium, and lead concentrations to residential levels less than 37 milligrams per kilogram (mg/kg), 75 mg/kg, and 500 mg/kg, or to nonresidential levels less than 200 mg/kg, 560 mg/kg, and 1,000 mg/kg, respectively. In addition to numerical cleanup levels, visible waste associated with the historical smelter operation will be addressed during the RA for the TFM Site (USEPA, 2008). Sediment: Protect human health and the environment by preventing direct contact, through the ingestion pathway, with arsenic, cadmium, and lead contaminated sediment by reducing arsenic, cadmium, and lead concentrations to levels less than 181 mg/kg, 813 mg/kg, and 500 mg/kg, respectively (USEPA, 2008).

Table 2-1 presents the RAO criteria that were developed for the TFM Site. The discussion in Sections 3.0 through 7.0 includes a comparison of sample results to these RAO criteria. Constituents that exceed RAO criteria are highlighted in the data summary tables for each section. * * * * Remedial Design Data Evaluation Report On-Site Soil and Waste Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_03_Final.doc 3-1 03/04/2013 3.0 ON-SITE SOIL AND WASTE 3.1 TOPOGRAPHIC SURVEY A topographic survey of the entire TFM Site was conducted to develop the base map for the RD, including the adjacent area south of the Strip Mine Pit. The survey has one-foot contours and is accurate to 0.05 ft on state plane coordinates. Ground surface elevations were established to within a minimum 0.01 vertical ft (above mean sea level [msl]) relative to an established United States Geological Survey (USGS) benchmark. The survey captured tops and bottoms of all slopes and all other breaklines. Property lines and utilities were also included in the survey. The base map for the RD is presented in Appendix A. Surveying services were provided by L.W. Survey Company of Tulsa, Oklahoma. 3.2 VISUAL WASTE SURVEY FINDINGS A visual waste survey was conducted to determine the extent of waste material outside of the former production area. Smaller areas of waste material exist on the TFM Site as driveway/road materials, in drainage channels, and discontinuous “waste pockets”. The visual waste survey was conducted by walking a grid pattern in larger areas, and individual transects for smaller areas. Where waste was identified, soil samples were collected to determine the extent of impacted soil prior to placing it in the consolidation cell. In conjunction with the visual survey, visual pits or trenches were dug in areas determined by field personnel during the RD field investigation activities to more narrowly define the vertical extent of waste materials. A total of 29 visual pits were completed. Figure 3-1 presents the locations of the visual pits (identified by a “VP” designator), and Table 3-1 summarizes the locations and waste depths. Visual pit profiles are presented in Appendix B and visual pit photographs are presented in Appendix C. Locations of waste materials identified outside of the delineated waste area were mapped to document all visible waste materials for future incorporation within the consolidation cell. Figure 3-2 presents the estimated depths of waste, as well as depicting the isolated waste areas outside of the former production area. Northwest Portion of TFM Site An area of waste in the northwest corner of the TFM Site was identified during the visual survey and further delineated with seven visual pits (VP-56 to VP-61). Analytical samples were collected at three locations (TR-42, TR-43, and TR-44), which are outlined on Table 3-2. The waste was isolated to a small area around TR-42 and extended approximately 0.5 ft deep. The waste was also present to an approximate depth of 1.0 ft deep in the area of TR-44, and this material extended south to the access Remedial Design Data Evaluation Report On-Site Soil and Waste Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_03_Final.doc 3-2 03/04/2013 road/driveway, including the drainage embankment. The two identified waste areas at TR-42 and TR-44 are isolated and do not connect to each other. An isolated waste area was also identified starting at the drainage embankment south of the access road/driveway at VP-62 and extended to TR-45. The waste was approximately 4.0 ft deep along the west bank of the drainage ditch, and samples were collected at TR-45. The isolated waste areas are depicted on Figure 3-2, and analytical results for TR-42, TR-43, TR- 44, and TR-45 are discussed further in Section 3.3.3 and summarized in Table 3-3. Western Portion of TFM Site The western portion of the TFM Site had three isolated areas of waste that were identified during the RD field investigation activities that are outside of the delineated waste area. These areas were identified as follows: An old road bed appears to be present going off the TFM Site at TR-40. An isolated area of waste approximately 0.5 to 1.0 ft deep was delineated and samples were collected at TR-40, TR- 50, TR-51, and TR-52 as outlined on Table 3-2. An additional isolated waste area was identified west of the residence on the west side of the access road/driveway. The area was delineated based up on observations from VP-63, VP-64, VP-65, and TR-48. The waste in this area was approximately 1.0 ft deep. Lastly, an isolated area of fine grained waste was identified in the area of TR-49. The fine grained waste was visible on the surface and present to a depth of 0.5 ft. Samples were collected from TR-49 as outlined in Table 3-2. The isolated waste areas are depicted on Figure 3-2, and analytical results for TR-40 and TR-49 through TR-52 are discussed further in Section 3.3.3 and summarized in Table 3-3. TFM Ponds During the RD field investigation activities visual pits were also completed within the defined waste area to evaluate various hills and piles of debris. Eight visual pits (VP-42 through VP-49) were completed on and near the banks of Ponds 2 and 3. Retorts line the inside and outside banks of both Pond 2 and Pond 3. Broken retorts and waste fill the space between the outside and inside retort linings of the pond banks. Waste was identified to 7.0 ft deep at VP-46, and this waste depth varied based upon depth of pond bank compared to original ground surface prior to pond construction. The visual pit locations are presented on Figure 3-1, and waste depths are summarized in Table 3-1. Remedial Design Data Evaluation Report On-Site Soil and Waste Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_03_Final.doc 3-3 03/04/2013 Mid-Site Ravine A bank is present that runs along the south side of the Mid-Site Ravine from the west side of the TFM Site approximately 900 ft to the east. Three visual pits were dug along the Mid-Site Ravine bank (VP-68 through VP-70). VP-68 and VP-70 contained waste to 5.0 ft deep, and no waste was encountered at VP- 69. Strip Mine Pit A large mound is present along the northeast corner of the Strip Mine Pit, and this mound is believed to be a result of strip mining activities. Three visual pits were completed (VP-51, VP-52, and VP-53). The south end of the mound (VP-51) consisted of a shale/coal mix. Waste was only present on the surface of the middle visual pit (VP-53), and waste was present to 4.5 ft deep at the north end of the mound (VP-52). Three visual pits were also dug along the north bank of the Strip Mine Pit (VP-50, VP-54, and VP-55). Waste was present to 1.0 ft deep on the eastern portion of the bank (VP-50), and only limited pieces of waste were present in the middle and western portion of the bank (VP-54 and VP-55). The visual pit locations are presented on Figure 3-1, and waste depths are summarized in Table 3-1. Based upon the collective visual observations from the RI and RD, depths of waste on the TFM Site were estimated and are presented in Figure 3-2. Visual observations include recorded waste depths from trenching activities for visual and analytical purposes. The isolated waste areas and estimated depth of waste are also presented on Figure 3-2. The volume of waste observed during RI and RD field activities was approximately 146,000 cubic yards (cy), and this volume will be verified during the remedial design. 3.3 SOIL SAMPLING FOR WASTE CHARACTERIZATION Surface and subsurface soil samples were collected from within the waste material area, the perimeter of the waste material area, and in isolated areas of waste. Samples were submitted to the Oklahoma State Environmental Lab (SEL) for off-site laboratory analysis of total arsenic, cadmium, and lead and Toxicity Characteristic Leaching Procedure (TCLP) arsenic, cadmium, and lead (Table 3-2 through Table 3-4). The intent of the sampling was to determine the vertical and horizontal extent of metals in excess of RAOs and to determine if the soil exhibited TCLP metals results above regulatory criteria. Surface and subsurface soil samples were collected as indicated on Table 3-2. All samples were collected using trenching techniques; however, samples of the large waste fragments were not collected. Sample collection began at the soil interface below the waste to determine the extent to which leaching had occurred into the native clay. One sample of the fine waste/soil matrix within the larger waste fragments was collected at TR-24, to further characterize these materials. Remedial Design Data Evaluation Report On-Site Soil and Waste Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_03_Final.doc 3-4 03/04/2013 Surface and subsurface soil analytical data from the RD were combined with the RI analytical data and compared against the RAOs for the TFM Site. Figures 3-3 through 3-5 present the combined RD and RI soil results compared to the RAOs at the respective sample depths (0 to 0.5 ft below ground surface [bgs], 0.5 to 2.0 ft bgs, and 2.0 to 4.0 ft bgs). Complete laboratory analytical data packages are presented in Appendix D. The approximate volume of soil exceeding RAOs for each depth interval is indicated below, and these estimates will be verified during the remedial design: Approximate Volume of Soil > RAOs Depth (ft bgs) Volume of soil > Non-Residential RAO (cy) Volume of soil < Non-Residential RAO and > Residential RAO (cy) 0 – 0.5 26,000 6,500 0.5 - 2 61,000 750 2 - 4 40,000 0 Total 127,000 7,250 Note: As evident on Figures 3-2 through 3-5, the majority of soil with RAO exceedances is co-located with visually observed waste. Based on this overlap, the soil volume estimates provided here should not be considered additive to the waste volume estimates provided in Section3.2. 3.3.1 Waste Material Area Results In the waste material area (Figure 3-1), soil samples were collected from the native clay under the waste to assess any apparent leaching of materials from the waste into the subsurface. Test pits were completed at six sample locations (TR-22 through TR-27) and analyzed for TCLP arsenic, cadmium, and lead. One sample of the fine waste/soil material within the matrix of the large waste material was collected from the 0 to 1.0 ft bgs interval at TR-24. A sample collection summary is presented in Table 3-2, and analytical results are presented in Table 3-4. Sample locations are presented on Figure 3-1, and trench diagrams including descriptions of the waste and thickness of the waste are presented in Appendix B and Appendix C. Waste materials present in the test pits ranged from fine grained waste down to 0.5 ft bgs to large pieces of broken retorts down to 5.0 ft bgs (Figure 3-2). The sample of fine grained material collected from the matrix of the large waste material from 0 to 1.0 ft bgs at TR-24 exceeded the TCLP criteria for cadmium and lead. All samples (TR-22 through TR-27) collected from the native clay under the waste were below the TCLP criteria. TCLP arsenic was not detected in any samples, TCLP cadmium was detected in two samples of native clay (TR-22 and TR-25), and TCLP lead was detected in one sample of native clay Remedial Design Data Evaluation Report On-Site Soil and Waste Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_03_Final.doc 3-5 03/04/2013 (TR-25). Based on the RI and RD data sets, leaching of metals into the native clay does not appear to be occurring. 3.3.2 Perimeter of Waste Material Area Results Soil samples were collected along the perimeter of the waste material area (Figure 3-1) to further characterize the horizontal and vertical extent of the waste material area. Soil samples were collected from the soil under the deepest occurrence of waste material to assess any apparent leaching of materials from the waste into the subsurface. If present, fine grained waste materials that had the appearance of soil were collected for characterization. Test pits were completed at twelve locations (TR-28 through TR-36, and TR-46 through TR-48) and analyzed for total arsenic, cadmium, and lead; and TCLP arsenic, cadmium, and lead. A sample collection summary is presented in Table 3-2, and analytical results are presented in Tables 3-3 and 3-4. Sample locations are presented on Figure 3-1, and trench diagrams including descriptions of the waste and thickness of the waste are presented in Appendix B and Appendix C. Waste materials were present at four test pit locations (TR-28, TR-29, TR-32, and TR-48) and ranged from 1.0 to 2.0 ft bgs in depth. No TCLP or RAO exceedances were noted in the sample intervals collected below the observed waste at TR-28, TR-29, TR-32, and TR-48. The following samples exhibited exeedances of TCLP criteria and/or RAOs: TR-30: A sample collected from 0 to 1.0 ft bgs at TR-30 exceeded the TCLP criteria for cadmium and lead, the residential and nonresidential RAOs for total cadmium and lead, and the residential RAO for arsenic. No TCLP or RAO exceedances occurred in the 1.0 to 3.0 ft bgs sample interval for TR-30. TR-34: The sample collected from the 0 to 0.5 ft bgs interval at TR-34 exceeded residential and nonresidential RAO for lead in both the primary sample and field duplicate. In addition, the field duplicate (TR-2002/SS02) collected from the 0 to 0.5 ft bgs interval at TR-34 exceeded the residential RAO for arsenic. No exceedances of the TCLP criteria were noted in the sample collected from 0 to 0.5 ft bgs. No exceedances of TCLP criteria or RAOs were noted in the 2.0 to 3.5 ft bgs sample interval for TR-34. TR-46: The sample collected from the 0 to 0.5 ft bgs interval at TR-46 exceeded the residential RAO for lead, and the sample collected from the 0.5 to 1.5 ft bgs interval exceeded the residential RAO for arsenic. No exceedances of TCLP criteria or RAOs were noted in the 1.5 to 3.0 ft bgs Remedial Design Data Evaluation Report On-Site Soil and Waste Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_03_Final.doc 3-6 03/04/2013 sample interval for TR-46. TR-47: A sample collected from 0 to 0.5 ft bgs interval at TR-47 exceeded the residential RAO for lead. No exceedances of the TCLP criteria or RAOs were noted in the 0.5 to 1.5 ft bgs and 1.5 to 4.0 ft bgs intervals. No other RAO or TCLP exceedances were noted for the samples designated as the perimeter of the waste area. 3.3.3 Isolated Waste Material Areas Results During the visual waste survey smaller areas of waste material were identified onsite as driveway/road materials, in drainage channels, and discontinuous “waste pockets”. Soil samples were collected from the soil under the deepest occurrence of waste material, and if present, fine waste materials that have the appearance of soil were collected for characterization. A total of 16 locations (TR-37 through TR-45 and TR-49 through TR-55) were sampled based upon visual survey findings and analyzed for total arsenic, cadmium, and lead; and TCLP arsenic, cadmium, and lead. A sample collection summary is presented in Table 3-2, and analytical results are presented in Tables 3-3 and 3-4. Sample locations are presented on Figure 3-1, and trench diagrams including descriptions of the waste and thickness of the waste are presented in Appendix B and Appendix C. Northwest Portion of TFM Site Analytical samples were collected at three locations (TR-42, TR-43, and TR-44) in the northwest corner of the TFM property identified during the visual survey. The waste is isolated to a small area around TR- 42 approximately 0.5 ft deep. In addition, the waste is present to an approximate depth of 1.0 ft deep in the area of TR-44, which extends south to the road and includes the drainage embankment. No TCLP or RAO exceedances were noted in the sample intervals collected below the observed waste at TR-42 and TR-44, or in the sample intervals collected at TR-43. An isolated waste area was also identified starting at the drainage embankment south of the road extending to TR-45. A sample was collected from the native clay below the waste, which was approximately 4.0 ft deep along the west bank of the drainage ditch. No exceedances of TCLP or RAOs were noted. Western Portion of TFM Site The western portion of the TFM site had two isolated areas of waste that were identified during the RD field activities that are outside of the delineated waste area. Remedial Design Data Evaluation Report On-Site Soil and Waste Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_03_Final.doc 3-7 03/04/2013 An old road bed appears to be present going off the site at TR-40. An isolated area of waste approximately 0.5 to1.0 ft deep was delineated and samples were collected at TR-40, TR-50, TR- 51, and TR-52. An exceedance of the residential RAO for cadmium was noted in the 0 to 0.5 ft bgs interval at TR-50, and this sample also exhibited an exceedance of the TCLP criteria for cadmium. No exceedances of RAOs or TCLP criteria were noted in samples collected below 0.5 ft bgs at TR-50. In addition, an exceedance of the residential RAO for lead was noted in the 0 to 0.5 ft bgs interval at TR-52, but not in samples collected below 0.5 ft bgs at this location. No other exceedances were noted of RAOs or TCLP criteria for samples collected in this area. An additional isolated waste area was also identified west of the residence on the west side of the road. An isolated area of fine grained waste was identified in the area of TR-49. No exceedances of RAOs or TCLP criteria were noted in samples collected from TR-49. Access Road/Driveway TR-37, TR-38, and TR-39 were collected along the access road to define vertical extent of waste along the road. Waste was present to 1.5 ft bgs at TR-37 and 1.0 ft bgs at TR-38. The residential RAO of cadmium was exceeded at the 1.5 to 2.0 ft bgs interval at TR-37. No exceedances were noted in the subsequent sample intervals at TR-37. No exceedances of RAOs or TCLP criteria were noted for samples collected from TR-38 and TR-39. 3.4 POTENTIAL BORROW MATERIALS SOIL SAMPLING AND DATA COLLECTION Soil samples were collected from seven test pits (TP-01 through TP-07) to evaluate the potential for on-site materials to be used as a borrow source for consolidation cell cap materials. ODEQ will review and approve the sample data and proposed borrow source locations before the borrow soil is removed and used. Test pit locations are presented on Figure 3-1. A sample summary is presented on Table 3-5, and analytical results are presented on Table 3-6. Trench/test pit diagrams including descriptions of the waste and thickness of the waste are presented in Appendix B. Soil samples were collected from below the root zone, or below waste materials if present, to 5.0 ft bgs. Samples were initially analyzed by SEL for total arsenic, cadmium, and lead. When these results were below the residential RAO for soil, additional soil samples were collected and submitted to SEL for further chemical evaluation for the presence of volatile organic compounds (VOCs), semivolatile organic compounds (SVOCs), Resource Conservation and Recovery Act (RCRA) Metals, pesticides, polychlorinated biphenyls (PCBs), and herbicides. Remedial Design Data Evaluation Report On-Site Soil and Waste Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_03_Final.doc 3-8 03/04/2013 Test pits were also used to collect disturbed geotechnical samples, and borings were used to collect undisturbed geotechnical samples. Samples were collected from below the root horizon to 5 ft bgs. Samples were submitted to a geotechnical laboratory (Standard Testing and Engineering Company in Tulsa, Oklahoma) for off-site analysis of Atterberg limits, sieve with hydrometer, specific water/moisture content, standard proctor, and modified proctor, which need to be performed on disturbed samples. Soil samples were also collected using Shelby tubes advanced using hollow stem augers (HSAs) to provide geologic information for logging and samples for geotechnical analysis for hydraulic conductivity and soil bulk density analyses, which need to be performed on undisturbed samples. Geotechnical data is presented in Appendix E, and will be discussed and evaluated during the Remedial Design Report. Soil samples were also collected and submitted to the Tulsa County Oklahoma State University Extension office for analysis of pH and N-P-K to determine fertility needs for maximum growing effectiveness. Soil fertility results are presented in Appendix E, and will be discussed and evaluated during the Remedial Design Report. A borrow material sample summary is presented in Table 3-5. Waste materials were not observed at TP-01 to TP-06; however, waste material was observed to 1.0 ft bgs at TP-07 (Figure 3-1). Borrow material samples were collected below the waste at TP-07 from the 1.0 to 5.0 ft bgs interval. The initial total arsenic, cadmium, and lead results were below the residential RAO for all test pit locations, and then screened against the borrow material values (arsenic – 20 mg/kg, cadmium – 20 mg/kg, and lead – 100 mg/kg) set forth by ODEQ. With the exception of arsenic, cadmium, and lead, results for the additional chemical parameters were screened using the residential soil values from the USEPA Regional Screening Level (RSL) Summary Table (USEPA, 2012). All RCRA metal detections (with the exception of lead in TP-06) were below the borrow material screening values or applicable residential soil RSLs for all test pit locations. No detections of VOC, SVOC, pesticide, PCB, or herbicide analytes were present in any samples collected from the seven test pits TP-01 to TP-07. Figure 3-6 presents potential borrow material areas located on the TFM Site. It is assumed that the root zone (0 to 0.5 ft bgs) will be removed prior to any borrow material excavation; therefore, Figure 3-6 is based upon collective analytical data from the 0.5 – 5.0 ft bgs interval from locations collected during the RI and RD. Based upon the potential borrow material areas depicted in Figure 3-6, and a depth of 0.5 to 5.0 ft bgs the volume of available borrow material is approximately 128,000 cy. * * * * * Remedial Design Data Evaluation Report Off-Site Soil and Waste Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_04_Final.doc 4-1 03/04/2013 4.0 OFF-SITE SOIL AND WASTE 4.1 VISUAL WASTE SURVEY FINDINGS Waste material has been observed to extend off-site to adjacent properties. Per the RD Work Plan, a visual waste survey was planned for all properties adjacent to the TFM Site. This visual survey was to be conducted by walking a 25 to 50 ft buffer zone around the perimeter of the TFM Site to identify areas where waste materials extended to off-site adjacent properties. However, due to access limitations the off-site visual survey could not be performed as outlined. For all areas, except the properties south of the Strip Mine Pit, the visual survey was performed by making observations from the TFM Site. Based on these observations, the following areas of apparent waste materials on adjacent properties were noted (See also Figure 4-1: Old roadbeds appear to be leaving the TFM site in the western portion of the property in a northwestern direction onto the adjacent Moore property. Another former road appears to be leaving the TFM site in the northwest portion of the TFM site in a northern direction onto the adjacent Faith Assembly Church Property. The TFM Site is bounded immediately to the east by the Atchison Topeka Santa Fe railroad tracks, currently owned and operated WATCO. An access agreement is not in place for this property and was not pursued for RD activities. Waste fragments were visually observed on the railroad property southeast of the Strip Mine Pit, as well as, an area approximately 100 ft in length southeast of Pond 1. A visual survey of the ridge south of the Strip Mine Pit was attempted from the west, but due to thick vegetation access was limited. A visual survey of the ridge south of the Strip Mine Pit was then conducted from a boat, and where possible, the ridge was traversed by foot. Waste material was observed on the surface in several areas of the ridge, and three samples were collected along the ridge (OSL-120 through OSL-122). Based upon the visual survey and analytical results from these samples, further investigation of the ridge south of the Strip Mine Pit was deemed necessary. On July 9 through July 12, 2012, clearing and grubbing activities occurred along the ridge south of the Strip Mine Pit, starting at the west area of the Strip Mine Pit to the eastern point of the ridge. Once clearing activities were completed a visual survey of the ridge was conducted. Small fragments of waste material were sporadically observed along the ridge and slopes and appeared only to be present on the Remedial Design Data Evaluation Report Off-Site Soil and Waste Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_04_Final.doc 4-2 03/04/2013 surface. Test pits were dug along the ridge (Figure 4-2, locations OSL-123 through OSL-131) and samples were collected and submitted to the SEL for off-site laboratory analysis of total arsenic, cadmium, and lead and TCLP arsenic, cadmium, and lead (Table 4-1). The adjacent property south of the north-south section of the Strip Mine Pit was also included in the off-site visual survey. An isolated waste area was identified and delineated (Figure 4-1). Test pits OSL-132 and OSL-133 were placed within this waste area to determine the vertical extent of waste, and samples were collected and submitted to the SEL for off-site laboratory analysis of total arsenic, cadmium, and lead and TCLP arsenic, cadmium, and lead (Table 4-1). 4.2 SOIL SAMPLING AND ANALYTICAL RESULTS Surface and subsurface soil samples were collected to further define off-site materials and the extent of impacted soil. All samples were collected using trenching techniques. Samples were collected from the 0 to 0.5 ft bgs, 0.5 to 2.0 ft bgs, and 2.0 to 4.0 ft bgs intervals, and analyzed for total arsenic, cadmium, and lead; and TCLP arsenic, cadmium, and lead. A sample collection summary is presented in Table 4-1, and analytical results are presented in Tables 4-2 through 4-4. Complete laboratory analytical data packages are presented in Appendix D. Sample locations are presented on Figure 4-2, and trench diagrams including descriptions of the waste and thickness of the waste are presented in Appendix B and Appendix C. Surface and subsurface soil analytical data from off-site were compared against the RAOs for the TFM Site. Figures 4-3 through 4-5 present the RD soil results compared to the RAOs at the respective sample depths (0 to 0.5 ft bgs, 0.5 to 2.0 ft bgs, and 2.0 to 4.0 ft bgs). The approximate volume of soil exceeding RAOs for each depth interval was in indiciated below, and these estimates will be verified during the remedial design: Approximate Volume of Soil > RAOs Depth (ft bgs) Volume of soil > Non-Residential RAO (cy) Volume of soil < Non-Residential RAO and > Residential RAO (cy) 0 to 0.5 630 390 0.5 to 2 1,700 1,800 2 to 4 2,000 380 Total 4,330 2,570 Note: As indicated on Figure 4-3, it was assumed that the impacted area included the entire first ridgeline that was south of the Strip Mine Pit. Based on the sporadic nature of the observed waste, the volume of impacted material presented here may be overestimated. Remedial Design Data Evaluation Report Off-Site Soil and Waste Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_04_Final.doc 4-3 03/04/2013 Initial Survey – South Ridge of Strip Mine Pit During the initial visual survey of the ridge south of the Strip Mine Pit, three sample locations (OSL-120, OSL-121, and OSL-122) were identified and samples were collected at three depth intervals. Results for samples collected from OSL-120 and OSL-121 were below the site-specific RAOs and TCLP criteria. Total lead results for the 0.5 to 1 ft bgs and 1 to 2.5 ft bgs intervals at location OSL-122 exceeded the residential and non-residential RAO. Additional Survey – South Ridge of Strip Mine Pit Based upon the sample results for the initial survey, further characterization of the ridge was deemed necessary. This characterization required clearing vegetation from the west end of the Strip Mine Pit along the ridge until it ended at its furthest east point, which intersects the north-south portion of the Strip Mine Pit. Once the clearing was completed, nine test pits were advanced into the initial ridge south of the Strip Mine Pit (OSL-123 through OSL-131). The test pits were located at the approximate locations of the Strip Mine Pit sediment sampling transects (See Section 5.0). Exceedances of the residential and/or non-residential RAOs for arsenic were noted for one sample in the 0 to 0.5 ft bgs interval (OSL-123), one sample in the 0.5 to 2 ft bgs interval (OSL-128), and three samples in the 2 to 4 ft bgs interval (OSL-125, OSL-127, and OSL-128). No exceedance of the RAOs was noted for cadmium. Exceedances of the residential and/or non-residential RAOs for lead were noted for three samples in the 0 to 0.5 ft bgs interval (OSL-125, OSL-127, and OSL-128), four samples in the 0.5 to 2 ft bgs interval (OSL-125, OSL- 126, OSL-127, and OSL-128), and three samples in the 2 to 4 ft bgs interval (OSL-125, OSL-126, and OSL-127). None of the TCLP results exceeded the TCLP criteria. Samples with exceedances were primarily located directly south of the former operations area of the TFM Site. Additional samples were collected from the 0 to 5 ft bgs interval at locations OSL-128 and OSL-131 to evaluate the potential to use soil from these locations as borrow material for the consolidation cell cap. The samples were submitted to SEL for analysis of VOCs, SVOCs, RCRA metals, pesticides, PCBs, and herbicides. The total arsenic, cadmium, and lead results were screened against the borrow material values (arsenic – 20 mg/kg, cadmium – 20 mg/kg, and lead – 100 mg/kg) set forth by ODEQ. With the exception of arsenic, cadmium, and lead, results for the additional chemical parameters were screened using the residential soil values from the USEPA RSL Summary Table (USEPA, 2012). All RCRA metal detections (with the exception of lead in OSL-128 and OSL-131) were below the site-specific RAOs or applicable residential soil RSLs. No detections of VOC, SVOC, pesticide, PCB, or herbicide analytes were present. Remedial Design Data Evaluation Report Off-Site Soil and Waste Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_04_Final.doc 4-4 03/04/2013 Isolated Waste Area – Southern Area of Strip Mine Pit An isolated waste area was identified on the adjacent property south of the north-south section of the Strip Mine Pit (Figure 4-1). Two test pits (OSL-132 and OSL-133) were located within this waste area to determine the vertical extent of waste and define the extent of impacted soil. Waste was present to 2 ft bgs at OSL-132, and present on the surface of OSL-133. An additional visual pit was dug between OSL- 132 and OSL-133, in which waste was present to 2 ft bgs. Based upon the visual observations from the RD, the volume of waste observed at the isolated waste area was approximately 1,200 cy, and this volume will be verified during the remedial design. The result for the sample collected from the 0 to 2 ft bgs interval at OSL-132 exceeded both the residential and non-residential RAO for lead. Exceedances of the residential RAO for arsenic were noted in the 0 to 0.5 ft bgs and 0.5 to 2 ft bgs interval at location OSL-133. No exceedances were noted of the TCLP criteria in these samples. * * * * * Remedial Design Data Evaluation Report Sediment Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_05_Final.doc 5-1 03/04/2013 5.0 SEDIMENT 5.1 SEDIMENT SAMPLING AND DATA COLLECTION During the RD field activities, sediment samples were collected to determine vertical extent of sediment contamination prior to placement in the consolidation cell. Samples were collected from TFM Pond 1, TFM Pond 2, TFM Pond 3, TFM Pond 4, the Mid-Site Ravine, and the Strip Mine Pit as indicated on Table 5-1. Sediment sampling locations are presented on Figure 5-1. TFM Ponds and Mid-Site Ravine Samples were collected from the 0 to 0.5 ft bgs interval from TFM Pond 1, TFM Pond 2, TFM Pond 3, TFM Pond 4, TFM Pond 5, and the Mid-Site Ravine during the RI for analysis of total arsenic, cadmium, lead, and zinc. The results from the RI indicated that metals results in excess of the site-specific sediment RAOs for arsenic, cadmium, and/or lead were encountered in the 0 to 0.5 ft bgs interval of TFM Pond 1, TFM Pond 2, TFM Pond 3, TFM Pond 4, and the Mid Site Ravine. Therefore, during the RD, additional samples were collected for analysis of arsenic, cadmium, and lead to further determine the vertical extent of contamination. In particular, samples were collected from the 0.5 to 1 ft bgs interval at TFM Pond 1 and TFM Pond 2, and samples were collected from the 0.5 to 1 ft bgs and 1 to 2 ft bgs intervals at TFM Pond 3, TFM Pond 4, and the Mid-Site Ravine. The sampling plan outlined in the FSP outlined collection of samples from both the 0.5 to 1 ft bgs and 1 to 2 ft bgs interval at each location. In several instances sediment samples were only collected 0.5 to 1.0 ft bgs interval due to encountering native material beneath the sediment shallower than 1.0 ft bgs. In such cases, the deepest sample was collected from the native materials beneath the sediment. Samples were also collected from one depth (0 to 0.5 ft bgs) at each location for analysis of TCLP arsenic, cadmium, and lead. Strip Mine Pit Samples were collected from the 0 to 0.5 ft bgs interval from the mid-section of the Strip Mine Pit during the RI, and none of the results exceeded site-specific RAOs for sediment. During the RD, sediment cores were collected from the Strip Mine Pit along transect lines at various distances from the shore (transect lines are illustrated on Figure 5-1) to characterize the extent of smelter materials slumping into the Strip Mine Pit. The cores were visually inspected for the presence of waste materials. Sample locations and depths were determined based on visual inspection of the cores. Results of the visual waste inspection of the Strip Mine Pit are presented on Table 5-2, and the estimated depths of waste are illustrated in Figure 5-2. Fine grained waste was observed predominantly on the north bank of the Strip Mine Pit and also on the east and west banks of the northern section. Waste was only observed in the 0 to 0.5 ft bgs interval. Remedial Design Data Evaluation Report Sediment Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_05_Final.doc 5-2 03/04/2013 Samples were collected from up to three depths at nine locations for analysis of total arsenic, cadmium, and lead to determine vertical extent of contamination. One sample was also collected at each location for analysis of TCLP arsenic, cadmium, and lead. 5.2 SEDIMENT RESULTS Analytical results for the RD data collection are provided on Tables 5-3 and 5-4. Complete laboratory analytical data packages are presented in Appendix D. Analytical sediment data from the RD were combined with the RI analytical data and compared against the RAOs and TCLP criteria for the TFM Site. Figures 5-3 through 5-5 present the combined RD and RI sediment results compared to the RAOs and TCLP criteria at the respective sample depths (0 to 0.5 ft bgs, 0.5 to 2.0 ft bgs, and 2.0 to 4.0 ft bgs). 5.2.1 TFM Pond 1 Results Sediment samples were collected from five locations in TFM Pond 1 during RD field activities. Two samples were collected from each location (0 to 0.5 ft bgs and 0.5 to 1.0 ft bgs). Samples collected from the 0 to 0.5 ft bgs interval were analyzed for TCLP arsenic, cadmium, and lead. Samples collected from the 0.5 to 1.0 ft bgs interval were analyzed for total arsenic, cadmium, and lead to determine the vertical extent of contamination. Native clay was uniformly observed at approximately 0.5 ft bgs at all sample locations in TFM Pond 1. The results from the RI indicated that metals results in excess of the site-specific sediment RAOs for arsenic, cadmium, and/or lead were encountered in the 0 to 0.5 ft bgs interval at TFM Pond 1. During the RD, one sample and its duplicate collected from 0.5 to 1 ft bgs at location PD1-05 had lead results in excess of the RAO. In addition, two samples had reporting limits for lead in excess of the RAO. One sample from the 0 to 0.5 ft bgs interval was submitted for analysis of TCLP arsenic, cadmium, and lead during the RI, and results for this sample were below the TCLP criteria. Five additional samples from the 0 to 0.5 ft bgs interval were submitted for TCLP analysis during the RD. The TCLP cadmium result from location PD1-04 (1.07 mg/L) slightly exceeded the 1 mg/L TCLP criteria. TFM Pond 1 is approximately 1.22 acres. Samples with metal results in excess of RAOs for sediment were encountered in both the 0 to 0.5 and 0.5 to 1 ft bgs intervals across TFM Pond 1. Assuming the depth of contamination is relatively uniform, the depth of contaminated sediment is approximately 1 ft deep. Therefore, approximately 1,970 cy of sediment above RAOs is estimated in TFM Pond 1 for inclusion in the consolidation cell. Only one location exhibited a minor exceedance of the TCLP criteria Remedial Design Data Evaluation Report Sediment Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_05_Final.doc 5-3 03/04/2013 at a depth of 0 to 0.5 ft bgs. Assuming that less than 10 percent of the TFM Pond 1 sediment exceeds TCLP criteria, approximately 100 cy of sediment is above the TCLP criteria. 5.2.2 TFM Pond 2 Results Sediment samples were collected from four locations in TFM Pond 2 during RD field activities. Two samples were collected from each location (0 to 0.5 ft bgs and 0.5 to 1.0 ft bgs). Samples collected from the 0 to 0.5 ft bgs interval were analyzed for TCLP arsenic, cadmium, and lead. Samples collected from the 0.5 to 1.0 ft bgs interval were analyzed for total arsenic, cadmium, and lead to determine vertical extent of contamination. Native clay was uniformly observed at approximately 0.5 ft bgs at all sample locations in TFM Pond 2. The results from the RI indicated that metals results in excess of the site-specific sediment RAOs for lead were encountered in the 0 to 0.5 ft bgs interval at TFM Pond 2. During the RD, three of the four sample locations (PD2-03, PD2-04, and PD2-06) had results that exceeded the residential/nonresidential RAO for lead in the 0.5 to 1.0 ft bgs interval. No exceedances of TCLP criteria or any additional RAO exceedances were noted in the sediment samples collected from TFM Pond 2 during RD activities. TFM Pond 2 is approximately 0.85 acres. Samples with metal results in excess of RAOs for sediment were encountered in both the 0 to 0.5 and 0.5 to 1 ft bgs intervals across TFM Pond 2. Assuming the depth of contamination is relatively uniform, the depth of contaminated sediment is approximately 1 ft deep. Therefore, approximately 1,370 cy of sediment above RAOs is estimated in TFM Pond 2 for inclusion in the consolidation cell. 5.2.3 TFM Pond 3 Results Sediment samples were collected from four locations in TFM Pond 3 during RD field activities. Samples were collected from three depth intervals (0 to 0.5 ft bgs, 0.5 to 1.0 ft bgs, and 1.0 to 2.0 ft bgs) at PD3-03 and PD3-05, and samples were collected at two intervals (0 to 0.5 ft bgs and 0.5 to 1.0 ft bgs) at PD3-04 and PD3-06. Samples collected from the 0 to 0.5 ft bgs interval were analyzed for TCLP arsenic, cadmium, and lead. Samples collected from the 0.5 to 1.0 ft bgs and 1.0 to 2.0 ft bgs intervals were analyzed for total arsenic, cadmium, and lead to determine vertical extent of contamination. Native clay was observed at approximately 0.5 ft bgs at PD3-04 and PD3-06, which were located in the deeper portions of TFM Pond 3. Native clay was observed at approximately 1.0 ft bgs at PD3-03 and PD3-05, which were located near the shoreline of TFM Pond 3. The results from the RI indicated that metals results in excess of the site-specific sediment RAOs for lead Remedial Design Data Evaluation Report Sediment Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_05_Final.doc 5-4 03/04/2013 were encountered in the 0 to 0.5 ft bgs interval at TFM Pond 3. During the RD, three of the four sample locations (PD3-03, PD3-05, and PD3-06) had results or an analytical reporting limit that exceeded the residential/nonresidential RAO for lead in the 0.5 to 1.0 ft bgs interval. In addition, the lead result for the 1 to 2 ft bgs interval at location PD3-03 exceeded the sediment RAO. No exceedances of the TCLP criteria were present at the 0 to 0.5 ft bgs interval in TFM Pond 3. TFM Pond 3 is approximately 0.70 acres. Samples with metal results in excess of RAOs for sediment were encountered to 1 ft bgs across Pond 3, and a limited area in the vicinity of the shoreline at PD3-03 had metals results in excess of RAOs to 2 ft bgs. Assuming the depth of contamination of approximately 1 ft bgs across the pond and an area approximately 10 percent of the pond contaminated to 2 ft bgs, approximately 1,240 cy of sediment above RAOs is estimated in TFM Pond 3 for inclusion in the consolidation cell. 5.2.4 TFM Pond 4 Results Sediment samples were collected from two locations in TFM Pond 4 during RD field activities. Three samples were collected from each location (0 to 0.5 ft bgs, 0.5 to 1.0 ft bgs, 1.0 to 2.0 ft bgs). Samples collected from the 0 to 0.5 ft bgs interval were analyzed for TCLP arsenic, cadmium, and lead. Samples collected from the 0.5 to 1.0 ft bgs and 1.0 to 2.0 ft bgs intervals were analyzed for total arsenic, cadmium, and lead to determine vertical extent of contamination. Native clay was observed at approximately 1.0 ft bgs at both sample locations. The results from the RI indicated that metals results in excess of the site-specific sediment RAOs for lead were encountered in the 0 to 0.5 ft bgs interval at TFM Pond 4. During the RD, both sample locations (PD4-02 and PD4-03) had results that exceeded the residential/nonresidential RAO for lead in the 0.5 to 1.0 ft bgs and 1 to 2 ft bgs depth intervals. No exceedances of the TCLP criteria were present at the 0 to 0.5 ft bgs interval in TFM Pond 4. TFM Pond 4 is approximately 0.08 acres. Samples with metal results in excess of RAOs for sediment were encountered to approximately 2 ft bgs across TFM Pond 4. Approximately 260 cy of sediment above RAOs is estimated in TFM Pond 4 for inclusion in the consolidation cell. 5.2.5 TFM Pond 5 Results One sediment sample was collected from TFM Pond 5 during the RI. Results for this sample were below the site-specific RAOs for sediment. Therefore, none of the sediment from TFM Pond 5 required Remedial Design Data Evaluation Report Sediment Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_05_Final.doc 5-5 03/04/2013 incorporation into the consolidation cell. 5.2.6 TFM Mid-Site Ravine Results Sediment samples were collected from five locations in along the Mid-Site Ravine that traverses the TFM Site near the former smelter operations during RD field activities. Three samples were collected from each location (0 to 0.5 ft bgs, 0.5 to 1.0 ft bgs, 1.0 to 2.0 ft bgs). Samples collected from the 0 to 0.5 feet bgs interval were analyzed for TCLP arsenic, cadmium, and lead. Samples collected from the 0.5 to 1.0 ft bgs and 1.0 to 2.0 ft bgs intervals were analyzed for total arsenic, cadmium, and lead to determine the vertical extent of contamination. The results from the RI indicated that metals results in excess of the site-specific sediment RAOs for arsenic and lead were encountered in the 0 to 0.5 ft bgs interval in the Mid-Site Ravine. During the RD, each of the sampling locations (MSR-04 through MSR-08) had results or an analytical reporting limit that exceeded the residential/nonresidential RAO for lead in the 0.5 to 1.0 ft bgs interval. Exceedances of the lead RAO were noted in samples collected from the 1 to 2 ft bgs interval at three locations (MSR-04, MSR-07, and MSR-08). The TCLP result for cadmium in four of five sample locations (MSR-04, MSR- 05, MSR-07, and MSR-08) exceeded the TCLP criteria at the 0 to 0.5 ft bgs interval. The Mid-Site Ravine cuts through the former operations area for the smelter, and waste materials were observed in the Mid-Site Ravine. The Mid-Site Ravine is approximately 1600 ft long and is up to 10 ft wide in places. Samples with metal results in excess of RAOs for sediment were encountered to 1 ft bgs throughout the Mid-Site Ravine, and approximately half of the sample locations exhibited metals results in excess of RAOs to 2 ft bgs. Assuming the depth of contamination of approximately 1 ft bgs across the Mid-Site Ravine and an area approximately 50 percent of the ravine contaminated to 2 ft bgs, approximately 900 cy of sediment above RAOs is estimated in the Mid-Site Ravine for inclusion in the consolidation cell. Assuming that all of the Mid-Site Ravine sediment to 0.5 ft bgs will exceed TCLP criteria, then approximately 350 cy of this contaminated sediment is above the TCLP criteria. 5.2.7 Strip Mine Pit Results Sediment samples were collected from the Strip Mine Pit along transect lines at nine sample locations (transect lines and sample locations are illustrated on Figure 5-1). Sample locations and depths were determined based on visual inspection of sediment cores collected along the transect lines (Table 5-2). Samples were collected from up to three depths for analysis of total arsenic, cadmium, and lead to determine vertical extent of contamination. One sample was also collected at each location for analysis of Remedial Design Data Evaluation Report Sediment Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_05_Final.doc 5-6 03/04/2013 TCLP arsenic, cadmium, and lead. Sample depths varied based upon depth to native material beneath sediment. Native clay and/or weathered shale were typically encountered at 0.5 ft bgs on near the banks of the Strip Mine Pit, and a silty clay was encountered to 2.0 to 3.0 ft bgs in the middle of the Strip Mine Pit. During the RI, sediment samples were collected from 0 to 0.5 ft bgs from six locations near the center line of the Strip Mine Pit. None of the results for these sediment samples exceeded the site-specific RAOs or the TCLP criteria. However, visual observations of waste material slumping into the Strip Mine Pit were made. During the RD, visual observations were made of sediment cores taken along 12 transects at various distances from the banks of the Strip Mine Pit. Table 5-2 presents a description of the visual observations and locations. Waste was observed to a depth of 0.5 ft bgs approximately 5 to 10 ft from the north bank of the Strip Mine Pit at transects SMPT-01 through SMPT-06. Waste was observed to a depth of 0.5 ft bgs approximately 5 to 10 feet from the south bank of the Strip Mine Pit at transect SMPT-09. Waste was observed to 0.5 ft bgs approximately 5 to 10 feet from the west bank at SMPT-10, as well as, approximately 5 to 10 feet from the east and west banks of SMPT-11 and SMPT-12. No waste was observed in the middle of the Strip Mine Pit at any transects. Figure 5-2 depicts the estimated depth of waste material at the Strip Mine Pit. Based on the visual observations, samples were collected from nine of the 12 transects. Sediment samples with lead concentrations at or above the RAO were encountered in the 0 to 0.5 ft bgs interval at all but SMPT-10. Lead exceeded RAOs at depths up to 2 ft bgs at transects SMPT-03, SMPT-05, and SMPT-08. No exceedances of RAOs were noted for arsenic or cadmium. In the 0 to 0.5 ft bgs interval, the TCLP result for cadmium at sample location SMPT-10-05 and the TCLP result for lead at SMPT-05- 05 exceeded the TCLP criteria. No other exceedances of TCLP criteria were noted. The Strip Mine Pit borders the southern edge of the TFM site. Based upon visual observations, fine grained waste was observed predominantly on the north bank of the Strip Mine Pit and also on the east and west banks of the northern section. Waste was only observed in the 0 to 0.5 ft bgs interval. Assuming the depth of fine grained waste is 0.5 ft bgs across areas highlighted on Figure 5-2, approximately 360 cy of sediment/fine grained waste is estimated for inclusion in the consolidation cell. Samples with metal results in excess of RAOs for sediment were encountered in the 0 to 0.5 ft bgs interval and also in the 0.5 to 1.0 ft bgs interval across the Strip Mine Pit. All areas of RAO exceedances for sediment in the 0 to 0.5 ft bgs interval will be removed with the fine grained waste, and the volume of sediment to be incorporated in the consolidation cell are included the 360 cy estimate. RAO exceedances Remedial Design Data Evaluation Report Sediment Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_05_Final.doc 5-7 03/04/2013 were present at two locations in the 0.5 to 1.0 ft bgs interval, and it is estimated that approximately 50 cy of sediment will be removed from that interval and incorporated into the consolidation cell. Two sample locations exhibited exceedances of the TCLP criteria at a depth of 0 to 0.5 ft bgs. Assuming that less than 20 percent of the Strip Mine Pit sediment exceeds TCLP criteria, approximately 70 cy of contaminated sediment is above the TCLP criteria. * * * * * Remedial Design Data Evaluation Report Surface Water Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_06_Final.doc 6-1 03/04/2013 6.0 SURFACE WATER 6.1 RD SURFACE WATER SAMPLING AND DATA COLLECTION Surface water samples collected during the RD were collected for the purpose of characterizing the water for management and/or discharge. It is anticipated that these water bodies may be drained and the water discharged prior to remedial action. Surface water samples were collected from TFM Pond 1, TFM Pond 2, TFM Pond 3, TFM Pond 4, the Mid-Site Ravine, and the Strip Mine Pit. Surface water samples were submitted for analysis of National Pollutant Discharge Elimination System (NPDES) parameters, which potentially include: arsenic, cadmium, lead, manganese, and zinc; total hardness; alkalinity; chloride; sulfate; total suspended solids (TSS); nitrate/nitrite as nitrogen; ammonia as nitrogen; chemical oxygen demand (COD); total organic carbon (TOC); biochemical oxygen demand (BOD-5); and, oil and grease. Field measurements of pH, specific conductivity, turbidity, temperature, and dissolved oxygen were collected during sampling. Table 6-1 provides a summary of the surface water samples, and analytical results are presented in Tables 6-2 through 6-4. Complete laboratory analytical data packages are presented in Appendix D. Surface water results were compared to the following criteria: Residential/non-residential RAO for cadmium, Oklahoma Pollutant Discharge Elimination System (OPDES) General Permit OKR05 for Storm Water Discharges for Industrial Facilities under the Multi-Sector Industrial General Permit within the State of Oklahoma, Sector L Landfills, Land Applications Sites, and Open Dumps, OPDES Permit Requirements for the Hudson Refining Superfund Site in Cushing, Oklahoma, which may indicate likely effluent limitations for the TFM Site. For purposes of data screening the lowest OPDES daily maximum limit was selected, as discharge for purposes of the RA is anticipated to be a one-time, not on-going occurrence. 6.1.1 TFM Pond 1 Surface Water Results One surface water sample and one field duplicate were collected from TFM Pond 1 in March 2012. The surface water sample was collected in the general area of the sediment sample PD1-06, as shown in Figure 5-1. The results for the surface water sample collected from TFM Pond 1 are presented on Table Remedial Design Data Evaluation Report Surface Water Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_06_Final.doc 6-2 03/04/2013 6-2. The zinc result in the surface water sample collected from TFM Pond 1, as well as the field duplicate (11,900 μg/L and 12,000 μg/L, respectively), exceeded the daily maximum for the OPDES General Permit OKR05 (200 μg/L). No other exceedances of screening criteria were present in the surface water sample collected from TFM Pond 1. 6.1.2 TFM Pond 2 Surface Water Results. One surface water sample was collected from TFM Pond 2 in March 2012. The surface water sample was collected in the general area of the sediment sample PD2-05, as shown in Figure 5-1. The results for the surface water sample collected from TFM Pond 2 are presented on Table 6-2. The zinc result in the surface water sample collected from TFM Pond 2 (1,490 μg/L) exceeded the daily maximum for the OPDES General Permit OKR05 (200 μg/L). No other exceedances of screening criteria were present in the surface water sample collected from TFM Pond 2. 6.1.3 TFM Pond 3 Surface Water Results One surface water sample was collected from TFM Pond 3 in March 2012. The surface water sample was collected in the general area of the sediment sample PD3-06, as shown in Figure 5-1. The results for the surface water sample collected from TFM Pond 3 are presented on Table 6-2. The zinc result in the surface water sample collected from TFM Pond 3 (2,200 μg/L) exceeded the daily maximum for the OPDES General Permit OKR05 (200 μg/L). No other exceedances of screening criteria were present in the surface water sample collected from TFM Pond 3. 6.1.4 TFM Pond 4 Surface Water Results One surface water sample was collected from TFM Pond 4 in March 2012. The surface water sample was collected in the general area of the sediment sample PD4-02, as shown in Figure 5-1. The results for the surface water sample collected from TFM Pond 4 are presented on Table 6-2. The zinc result in the surface water sample collected from TFM Pond 4 (933μg/L) exceeded the daily maximum for the OPDES General Permit OKR05 (200 μg/L). No other exceedances of screening criteria were present in the surface water sample collected from TFM Pond 4. 6.1.5 Mid-Site Ravine Surface Water Results Surface water samples were collected from four locations (MSR-05 through MSR-08) within the Mid-Site Ravine in March 2012. The surface water samples were collected in the general area of the sediment samples MSR-05 through MSR-08, as shown in Figure 5-1. The results for the surface water sample Remedial Design Data Evaluation Report Surface Water Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_06_Final.doc 6-3 03/04/2013 collected from Mid-Site Ravine are presented on Table 6-3. The zinc results in all four surface water samples collected from the Mid-Site Ravine (ranged from 1,630 to 11,600 μg/L) exceeded the daily maximum for the OPDES General Permit OKR05 (200 μg/L). The Oil and Grease result for the surface water sample collected at MSR-05 (35.7 milligrams per liter [mg/L]) exceeded the daily maximum for the Oil and Grease criteria based on the Hudson Refining Superfund Site OPDES Permit (15.0 mg/L). This result should be verified prior to the RA as all other Oil and Grease results were non-detect. The cadmium result for the surface water sample collected at MSR-08 (286 μg/L) exceeded the surface water RAO for cadmium (238 μg/L). It should be noted that the highest concentrations of metals were at location MSR-08, which also exhibited the highest TSS and turbidity. No other exceedances of screening criteria were present in the surface water samples collected from the Mid-Site Ravine. 6.1.6 Strip Mine Pit Surface Water Results Surface water samples were collected from three locations (SMPT-06, SMPT-08, and SMPT-11) within the Strip Mine Pit in March 2012. The surface water samples were collected in the general area of the sediment samples transects SMPT-06, SMPT-08, and SMPT-11, as shown in Figure 5-1. The results for the surface water sample collected from Strip Mine Pit are presented on Table 6-4. The sulfate results in all three surface water samples collected from the Strip Mine Pit (ranged from 631 to 643 mg/L) exceeded the daily maximum for the sulfate criteria (550 mg/L), which is based on the Hudson Refining Superfund Site OPDES Permit. No other exceedances of screening criteria were present in the surface water sample collected from the Strip Mine Pit. * * * * * Remedial Design Data Evaluation Report Ground Water Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_07_Final.doc 7-1 03/04/2013 7.0 GROUND WATER 7.1 HYDROGEOLOGY No major bedrock or alluvial aquifers lie beneath the TFM Site. The Seminole Formation, the upper bedrock beneath the TFM Site, consists of shale, sandstone, and thin coal beds and has a thickness of approximately 200 ft. The Seminole Formation reportedly yields small amounts of fair to poor quality water and has been designated Class IIB as a minor use general basin (OAC, 2004). There are no municipal or other public water wells or Wellhead Protection Areas within a 4-mile radius of the TFM Site. Based on RI and RD activities, the occurrence of ground water beneath the TFM Site is very limited; however, it does appear to be continuous across the TFM Site. A hydrogeological investigation was conducted during the RD to meet the requirements of OAC 252:515. The hydrogeologic investigation was designed to meet permit requirements for the consolidation cell. Based on the assumption of an approximate ten acre consolidation cell, six borings were installed to 30 ft below the lowest elevation of the bottom of the waste materials in the consolidation area and these locations are shown on Figure 7-1. One boring (B-05) was advanced to approximately 100 ft bgs. Borings were advanced to bedrock (approximately ten ft bgs) using “dry methods” and were advanced to total depth using coring methods. Lithologic logs were prepared for each boring, and are presented in Appendix E. One geotechnical soil sample was collected from each type of soil encountered. Previous investigations indicated there were up to four types of unconsolidated materials present at the TFM Site: a silty loam/silty sand; a clay; a lower silty loam/silty sand; and the waste material. The geotechnical soil samples were submitted for analysis of Atterberg limits, hydraulic conductivity, sieve with hydrometer, and specific water/moisture content. Geophysical logging using gamma ray/neutron logs was performed at three of the borings (B-03, B-04, and B-05). The geophysical data and geotechnical data are presented in Appendix E and will be evaluated during the remedial design. 7.2 MONITORING WELL INSTALLATION Four monitoring wells (MW-07, MW-08, MW-09, and MW-10) were installed to monitor ground water elevation in the proposed consolidation cell area (Figure 7-1). Based upon previous investigations, ground water is present in an unconfined condition in a thin zone located directly above bedrock. A lithologic log was prepared for each boring and is presented in Appendix E. Borings were continuously sampled to the top of bedrock using a HSA drilling techniques. The monitoring wells were constructed with five ft of screen that straddles the top of ground water. Following installation, each monitoring well was developed in accordance with SOP TFM-107 which is provided in the RD FSP. Additionally, each Remedial Design Data Evaluation Report Ground Water Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_07_Final.doc 7-2 03/04/2013 monitoring well was surveyed in order to obtain horizontal coordinates and top of casing elevation data. Monitoring well construction details are presented in Table 7-1. Monitoring well survey data, well development forms, field sampling forms, construction diagrams, and drilling logs are located in Appendix E. 7.3 WATER LEVEL MEASURMENT COLLECTION Ground water elevation measurements are being collected monthly in accordance with OAC 252:515 Subchapter 7, Part 5, Ground Water Study. Table 7-2 presents monthly ground water elevations collected to date at the TFM Site. Water level gauges were installed in all four ponds and the Strip Mine Pit, and surface water elevation measurements (Table 7-3) are recorded monthly at the same time of ground water elevation measurements. Although ground water elevation measurements are only required for the four piezometers in close proximity to the proposed consolidation cell, ground water elevation measurements are collected from all of the TFM Site monitoring wells, including seven existing monitoring wells and four new monitoring wells. On March 29, 2012 a datalogger was installed in monitoring well MW-02 to provide continuous hourly ground water elevation data. Ground water data from the data logger will be downloaded at the same time as the monthly ground water elevations are collected. Figures 7-2 to 7-4 present the potentiometric surface maps that were constructed based upon ground water level measurements during each quarterly sampling event. Ground water flow direction was toward the southeast for each sampling event. Monthly potentiometric surface maps, ground water levels (including from the data logger) will be presented in detail under a separate Ground Water Report. 7.4 MONITORING WELL SAMPLING AND DATA COLLECTION RI data indicates that waste materials are present at depths that could intercept shallow ground water. Three ground water sampling events conducted during the RI indicated that contamination is not present in ground water and migrating off-site; this determination was made using six on-site wells and one downgradient off-site well. Although not required during the design phase, quarterly ground water sampling of seven existing and four newly installed monitoring wells is being conducted to add to the RI data that support the determination that contamination is not present in ground water and migrating off-site. The first three quarterly ground water sampling events were conducted on April 16-17, 2012, July 10-11, 2012, and October 15-16, 2012. Monitoring Wells MW-01 to MW-10 were sampled using low-flow sample collection techniques with a peristaltic pump and Teflon-line polyethylene tubing. Samples were collected from each well and submitted to SEL for analysis of arsenic, cadmium, and lead, as both field- Remedial Design Data Evaluation Report Ground Water Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_07_Final.doc 7-3 03/04/2013 filtered and unfiltered samples, as volume allowed. During the July 2012 sampling event, only total metals were collected from Monitoring Well MW-08, due to limited sample volume. Tables 7-4 through 7-14 presents the analytical ground water results from the first two quarterly ground water sampling events (third quarter analytical data was not available at the time of this report) during the RD, as well as analytical groundwater data from the three sampling events conducted during the RI at Monitoring Wells MW-1 to MW-06. Complete laboratory analytical data packages are presented in Appendix D. The analytical results of the ground water sampling events will be discussed in detail under a separate Ground Water Report. * * * * * Remedial Design Data Evaluation Report Ecological Evaluation Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_08_Final.doc 8-1 03/04/2013 8.0 ECOLOGICAL EVALUATION 8.1 ECOLOGICAL SITE RECONNAISSANCE An ecological site reconnaissance was completed on March 15, 2012 by a BMcD biologist familiar with the regional flora and fauna. The TFM Site is located within the Osage Cuestas (Level IV) ecoregion of Oklahoma (Woods, 2005). The Osage Cuestas ecoregion is an irregular to undulating plain that historically consisted mostly of tall grass prairie with some oak–hickory and riparian forests. The native vegetation communities were converted to managed rangeland and cropland as the area was settled and developed. The TFM Site is vegetated by various grass species, trees, and shrubs creating diverse habitat types. There are areas of dense woody vegetation interspersed with sparsely vegetated grassy areas and patches of bare or rocky ground. The open grassy areas at the TFM Site included Bermuda grass (Cynodon dactylon), little bluestem (Schizachyrium scoparium), Johnson grass (Sorghum halepense), tall dropseed (Sporobolus asper), bristle grass (Seteria spp.), Canada goldenrod (Solidago canadensis), Oklahoma blackberry (Rubus oklahomus), and scattered green hawthorn (Crataegus virdis), eastern red cedar (Juniperus virginiana), and smooth sumac (Rhus glabra) shrubs. Wooded areas included blackjack oak (Quercus marilandica), eastern red cedar, hackberry (Celtus occidentalis), elm (Ulmus spp.), dogwood (Cornus spp.), Japanese honeysuckle (Lonicera japonica), and saw greenbrier (Smilax bona-nox). Species present in the wetter areas along the edges of the ponds included boxelder (Acer negundo), American sycamore (Platanus occidentalis), eastern cottonwood (Populus deltoides), black willow (Salix nigra), button bush (Cephalanthus occidentalis), smartweed (Polygonum spp.), and common cattail (Typha latifolia). Minimal wildlife was observed during the November 27, 2006, RI field survey; however, several common wildlife species were observed during the March 15, 2012, field survey. These species included northern cricket frog (Acris crepitans), plains leopard frog (Rana blairi), ground skink (Scincella lateralis), five-lined skink (Eumeces faciatus), common garter snake (Thamnophis sirtalis), Northern Cardinal (Cardinalis cardinalis), Northern Mockingbird (Mimus polyglottos), American Robin (Turdus migratorius), Downey Woodpecker (Picoides pubescens), Red-winged Blackbird (Agelaius phoeniceus), Killdeer (Charadrius vociferous), and European Starling (Sturnus vulgaris). At the north end of the TFM Site, Wild Turkey (Meleagris gallopavo) feathers were observed in wooded and grassy areas and several skinks had been impaled on spines in hawthorn trees by a Loggerhead Shrike (Lanius ludovicianus). Additional wildlife species that likely occur on the TFM Site but not observed during the field surveys Remedial Design Data Evaluation Report Ecological Evaluation Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_08_Final.doc 8-2 03/04/2013 include Woodhouse’s toad (Bufo woodhousei), box turtle (Terrapene spp.), black ratsnake (Elaphe obsoleta), racer (Coluber constrictor), fox squirrel (Sciurus niger), raccoon (Procyon lotor), opossum (Didelphis virginiana), striped skunk (Mephitis mephitis), red fox (Vulpes fulva), coyote (Canis latrans), white-footed mouse (Peromyscus leucopus), eastern cottontail (Sylvilagus floridanus), white-tailed deer (Odocoileus virginianus), mourning dove (Zenaida macroura), cooper’s hawk (Accipiter cooperii), barn swallow (Hirundo rustica), and scissor-tailed flycatcher (Tryannus forficatus). These are common species that are typically found in areas that exhibit varying amounts of disturbance. Hunting decoys were present in the on-site ponds during the 2006 field survey; however, no waterfowl were observed during the 2006 and 2012 field surveys. It was assumed that waterfowl would be present on the ponds at the TFM Site at least some time during the year. During a site visit conducted during USEPA’s Removal Assessment, local fishermen reported that catfish and bass were present in the southern strip mine pit (USEPA, 1999). According to the U.S. Fish and Wildlife Service (USFWS) and Oklahoma Natural Heritage Inventory (ONHI) database (ONHI, 2003), the following protected species are known or are likely to occur in Tulsa County: Common Name Scientific Name Federal Status State Status American Burying Beetle Nicrophorus americanus Endangered Endangered Bald Eagle Haliaeetus leucocephalus Delisted Endangered Least Tern Sterna antillarum Endangered Endangered Piping Plover Charadrius melodus Threatened Threatened Texas Horned Lizard Phrynosoma cornutum -- Candidate However, none of the protected species known or likely to occur in Tulsa County were observed at the TFM Site and none are likely to occur because of the disturbed nature of the TFM Site and amount of development in the vicinity of the TFM Site. No bald eagles, which prefer to nest and roost in large trees and snags along large rivers and reservoirs, were observed during the site visit. Similarly, no raptor stick nests were present in any of the trees at or in the immediate vicinity fo the TFM Site. According to the USFWS, Tulsa County is situated along the probable migratory pathway for the Least Tern and Piping Plovers between breeding and wintering habitats. Tulsa County also contains sites (e.g., Remedial Design Data Evaluation Report Ecological Evaluation Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_08_Final.doc 8-3 03/04/2013 isolated sandbars along the Arkansas River) that could provide stopover habitat during the migration. Potential nesting and loafing habitat for Least Terns and Piping Plovers, which includes sandbars in large rivers like the Arkansas River, is not present at the TFM Site. Although Texas horned lizards occur in open areas with clumping grasses for cover, they are unlikely to occur at the TFM Site because of the amount of disturbance and broken retorts and condensers, slag, building debris, ash, and bricks present in the open areas. 8.2 AMERICAN BURYING BEETLE SURVEY Prior to the start of the RD, a survey was conducted at the TFM Site for the American Burying Beetle (ABB), September 12-19, 2011, by Eagle Environmental Consulting, Inc. of Vinita, Oklahoma. No ABBs were present on the TFM Site. The survey was valid until May 20, 2012. A copy of the ABB survey is provided in Appendix F. An ABB survey was also completed in support of the RI and no ABBs were present on the TFM Site at that time. * * * * * Remedial Design Data Evaluation Report Air Monitoring Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_09_Final.doc 9-1 03/04/2013 9.0 AIR MONITORING 9.1 PERIMETER AIR MONITORING Results of perimeter air monitoring conducted during the RI indicated that the TFM Site was not a source of airborne contamination to off-site locations (BMcD, 2007). No additional perimeter air sampling was deemed necessary for the RD. 9.2 PERSONAL AIR MONITORING Exposure monitoring of site personnel was conducted during activities that disturbed soil and/or waste material (i.e. trench sampling or soil borings). Real-time dust monitoring was also conducted to measure total dust during active soil and/or waste disturbance activities. Real-time dust readings were recorded during the excavation of test pits and trenching activities which occurred on March 6-7, 2012. Real-time dust results were below the 0.3 milligrams per cubic meter (mg/m3) action limit in the RD HSP; therefore, no upgrade in personal protective equipment (PPE) was required. Results of real-time dust levels are presented in Appendix G. In addition, personal air monitoring was conducted during the initiation of field activities that disturb soil and/or waste materials. The initial monitoring was used to judge expected ranges of exposure for workers and to select appropriate levels of PPE. Personal air monitoring was completed on March 6-7, 2012. Personal sampling pumps with an inline cassette were attached to the equipment operator digging the test pits/trenches, BMcD field personnel collecting samples from the test pits/trenches, and BMcD field personnel performing soil logging of the monitoring well/boring installations. The personal sampling pumps were worn for the duration of the work shift. Samples were submitted for analysis of arsenic, cadmium, and lead. All samples were non-detect for arsenic and cadmium, and two samples had low-level detections of lead. The lead detections of 1.1 micrograms per cubic meter (μg/m3) and 1.4 μg/m3 were below the permissible exposure limit (PEL) of 50 μg/m3. Results of the personal air monitoring are presented in Appendix G. * * * * * Remedial Design Data Evaluation Report Waste Consolidation Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_10_Final.doc 10-1 03/04/2013 10.0 WASTE CONSOLIDATION 10.1 INVESTIGATION DERIVED WASTE IDW generated during the RD was disposed of on-site in accordance with the Guide to Management of Investigation-Derived Wastes (USEPA, 1992). All solid IDW generated from soil borings, soil sampling, and monitoring well installation was spread on the ground surface around the location from which it was generated. All liquid IDW generated from monitoring well development and purging, surface water sampling, and monitoring well sampling was discharged near the location from which it was generated. Eleven (11) drums of IDW generated during the RI were still on-site at the start of the RD field activities. Due to the poor condition of the IDW drums, the ODEQ project team was consulted, and it was decided that they would be incorporated into the waste area. The 11 drums were moved to the area near TR-25. The solid IDW was removed from the drums and incorporated into a trench in the waste area. The empty drums were then compacted and incorporated into the trench. Handling the IDW in this manner is appropriate since it does not pose unacceptable risk to human health and the environment in the interim and any potential risks that are posed in the long term by the wastes will be addressed by the remedy as defined in the record of decision (ROD). 10.2 WASTE TIRES Individual and piles of waste tires were present on the TFM Site, specifically in the area south of the former residence. During the RD field activities, the waste tires were consolidated to the TFM Site gate, and removed by the ODEQ Land Protection Division for recycling. * * * * * Remedial Design Data Evaluation Report References Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_11_Final.doc 11-1 03/04/2013 11.0 REFERENCES Burns & McDonnell Engineering Company, Inc.

(BMcD), under contract with the Oklahoma Department of Central Services (DCS) Construction and Properties Division (DCS Project #12069C / PO# 2929014842) on behalf of the Oklahoma Department of Environmental Quality (ODEQ), is conducting a remedial design (RD) for the Tulsa Fuel and Manufacturing site in Collinsville, Oklahoma (TFM Site). The RD is 100 percent federally funded through a Cooperative Agreement (CA) between the ODEQ and the United Stated Environmental Protection Agency (USEPA). A description of the RD project is included in Section 1 of the Remedial Design Work Plan, Tulsa Fuel and Manufacturing, Collinsville, Oklahoma (RD Work Plan) (BMcD, 2012e). 1.1 OBJECTIVES This Remedial Design Data Evaluation Report has been prepared by BMcD, as required in the Consultant Statement of Work for the Remedial Design for the Tulsa Fuel and Manufacturing Superfund Site (ODEQ, 2011), to compile and tabulate soil, sediment, waste, and geological data obtained during the RD field investigation activities. Data were compared to applicable remedial action objectives (RAOs) to determine the extent of materials requiring remediation and a preliminary estimate of the volume of the materials requiring placement in the consolidation cell and/or potential stabilization during the remedial action. In addition, an evaluation of soils at the TFM Site for potential use as borrow material for the consolidation cells was performed, and data collected to support the requirements of Oklahoma Administrative Code (OAC) Title 252. Department of Environmental Quality, Chapter 515. Management of Solid Waste, Subchapter 7. Subsurface Investigation (OAC 252:515-7) for the consolidation cell are provided. This Data Evaluation Report provides information obtained during the RD field investigation activities conducted from March 1 through July 13, 2012, including field observations, sample collection, laboratory analytical results, and data screening. RD field activities included: site reconnaissance, including topographic survey and visual waste survey sampling of on-site surface and subsurface soil to verify the extent and volume of soil and waste material requiring remediation sampling of off-site (south of the Strip Mine Pit) surface and subsurface soil to verify the volume of soil and waste material requiring remediation sampling of on-site subsurface soil to evaluate potential on-site borrow sources for cap material for the consolidation cell Remedial Design Data Evaluation Report Introduction Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_01_Final.doc 1-2 03/04/2013 soil profiling and monitoring well installation to collect piezometric elevation measurements to meet permit requirements for the consolidation cell sampling of on-site sediment to determine vertical extent of sediment contamination sampling of on-site surface water for characterization of discharge purposes recycling of waste tires on-site incorporation of remedial investigation (RI) investigation-derived waste (IDW) into defined waste area ecological site reconnaissance ambient air monitoring and personal exposure monitoring 1.2 DOCUMENT ORGANIZATION This Remedial Design Data Evaluation Report presents a summary of RD investigation activities and sample results.

The TFM Site is located in the NE1/4 SE1/4 NE1/4 Section 31 and SW1/4 NW1/4 Section 32 Township 22 North Range 14 East in Tulsa County, Oklahoma, and has the coordinates of 36° 20’ 45.59” north latitude and 95° 50’ 51.28” west longitude. As shown on Figure 1-1, the area within the TFM Site boundary consists of approximately 60.7 acres and is bounded by “Old” U.S. Highway 169 and the Atchinson Topeka Santa Fe railroad tracks (currently operated by WATCO) to the east; a flooded strip mine pit from a former coal mining operation to the south; and, agricultural and residential lots to the north and west (Oklahoma State Department of Health [OSDH], 1992 and ODEQ, 2011). Additionally, property owned by the Faith Assembly Church property bounds the TFM Site to the north. The Collinsville Smelter, which is another former zinc smelter, is located approximately one-fourth mile to the east-northeast of the TFM Site (Figure 1-1) on 220 acres of property formerly owned by the Bartelsville Zinc Company, and it is undergoing investigation and remediation (ODEQ, 2011). The majority of the facility structures have been demolished. Previous studies have indicated that portions of the TFM Site are covered with waste consisting of broken retorts and condensers, slag, building debris, ash, bricks, and other materials from the former smelting operations (BMcD, 2007). This waste area is located to the south of the access road/driveway (Figures 1-2 and 1-3). During the RI, waste materials were visually observed at the surface or within borings or trenches across approximately 25 acres. In addition, the access road/driveway was observed to contain waste materials. The waste varies in thickness from 2-feet (ft) to greater than 6-ft. The waste piles are not covered, and run-off is Remedial Design Data Evaluation Report Introduction Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_01_Final.doc 1-4 03/04/2013 uncontrolled. The waste borders the southern strip mine pit, and portions of the waste have collapsed into the impoundment. This impoundment, which receives surface water runoff from the TFM Site, is reportedly a local fishery and flows into an intermittent drainage ditch that borders on the eastern edge of the waste (BMcD, 2007). An intermittent stream originates in this area and flows approximately three quarter of a mile before draining into Blackjack Creek, which is located east of the TFM Site (Figures 1-1 and 1-2). Three intermittent ponds, which are assumed to be remnants of a 2-million gallon reservoir, are located north of the former smelter operations area (BMcD, 2007). In addition, two smaller ephemeral ponds are located on the TFM Site (Figure 1-3). The area north of the access road/driveway is vegetated with grasses (Figure 1-3). With the exception of the southern boundary at the strip mine pit, a 6-ft chain link fence surrounds the TFM Site. A residence (Figures 1-2 and 1-3), which was occupied from 1935 through February 2002, was located on the site near the former office building (paymaster hut). The on-site residence was destroyed by a fire and is currently unoccupied. The residence has a water well that was used in the past for drinking water, but it is no longer in use. No other residential structures are located on the Site; however, a garage and a few storage sheds remain adjacent to the former residence (ODEQ, 2011). A cistern is located just north of the mid-site ravine intermittent drainage that travels west to east across the former operation area of the TFM Site (Figure 1-3). Waste material at the TFM Site has impacted soil, sediment, and surface water. Ground water at the TFM Site has not been impacted (ODEQ, 2011). 1.4 SITE HISTORY During World War I zinc was in great demand. It was used to galvanize armaments to prevent rust. A zinc smelter and lead roaster were at the TFM Site from 1914 through 1925. Historically, the smelter was known as the Prime Western Smelter. The TFM Site was also misnamed as the Acme Brick Strip Mines site, since it was immediately adjacent to a strip mine on its southern boundary. Use of the land prior to the smelting operation is unknown (OSDH, 1992). The smelting operation utilized nine furnaces, approximately 150 ft in length by 60 ft wide, which were believed to be fueled by nearby natural gas wells. Other main structures of the smelter included a mechanical kiln building approximately 240 ft by 80 ft in size, a condenser room approximately 75 ft by 50 ft in size, and a laboratory (See Figure 1-2). A 2-million gallon capacity reservoir was used in conjunction with the condenser room during smelting operations. In addition, large amounts of ore were stored on the TFM Site in the area northeast of the waste piles (Figure 1-2). Little is known about waste management at the smelter during its operation. Due to the time period in which the smelter operated, it is unlikely that air emission control devices were used (ODEQ, 1994 and OSDH, 1992). Remedial Design Data Evaluation Report Introduction Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_01_Final.doc 1-5 03/04/2013 Strip mining occurred in the surrounding area. Immediately south of the TFM Site was a strip mining operation approximately 40 acres in size, which was known as the Acme Brick Strip Mine (OSDH, 1992). A water-filled surface impoundment (i.e., Strip Mine Pit), which acts as a southern boundary to the TFM Site, is currently associated with the former strip mine. It has been reported that this impoundment serves as a local fishery. Another strip mine area operated just east of the TFM Site, and one was located in northeast Collinsville (Figure 1-1). The Collinsville Smelter, which is being evaluated through ODEQ’s Voluntary Cleanup Program, is located approximately one quarter of a mile to the east-northeast of the TFM Site (Figure 1-1). The Bartelsville Zinc Company owned and operated this zinc smelter between 1911 and 1918. The Bartelsville Zinc Company owned 220 acres of land surrounding the Collinsville Smelter, and an area of approximately 40 acres has been designated as the location where the primary smelter activities occurred. In 1987, the Collinsville Smelter was reclaimed and regraded by the Oklahoma Conservation Commission (OCC) in conjunction with reclamation of the adjacent coal strip mine (Exponent, 2001). The majority of the structures have been demolished, but several foundations and building footings remain on the TFM Site. On September 28, 1928, the 120-foot tall and 11-foot diameter smokestack was imploded. A residence (Figure 1-2), which was occupied from 1935 through February 2002, was located on the TFM Site near the former office building (paymaster hut). The on-site residence was destroyed by a fire and is currently unoccupied. No other residential structures are located on the TFM Site; however, a garage and a few storage sheds remain in place adjacent to the former residence. Although the TFM Site is fenced on all sides except for the Strip Mine Pit, there is evidence of trespassing. There is abundant evidence of fishing and hunting activity around the ponds on the TFM Site, and fishing in the ponds has been reported on several occasions. In addition, individuals have been observed picking blackberries along the eastern fenced boundary and evidence of off-road vehicle traffic is present. The area in the vicinity of the on-site residence, including the garage and storage sheds and along the access road/driveway, has become a dumping area. Broken appliances, used exercise equipment, tires, junked cars, and assorted trash/debris were observed during the RD field activities. * * * * * Remedial Design Data Evaluation Report Introduction to Data Presentation and Evaluation Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_02_Final.doc 2-1 03/04/2013 2.0 INTRODUCTION TO DATA PRESENTATION AND EVALUATION 2.1 FINAL CLEANUP LEVELS RAOs are the cleanup objectives for protection of human health and the environment. ODEQ and USEPA developed RAOs for TFM Site soil, sediment, surface water, and waste material. Cleanup levels were established for both residential and nonresidential soil. These site-specific cleanup levels are the desired endpoint concentrations that provide adequate protection of human health and the environment for each exposure route. Although the TFM Site is currently unused vacant land, it is reasonable that future land use may be zoned residential based on development interest in the general area. Cleanup to residential levels will result in partial unlimited use, unrestricted exposure, and will be protective for human and terrestrial ecological receptors. The cleanup levels for the TFM Site are presented on Table 2- 1. Materials such as broken retorts and condensers, slag, and other smelter related materials represent a primary source material at the Site (USEPA, 2008). Although the contaminated soils present at the TFM Site represent a source material, they are not characterized as a “principal threat waste” because the resulting soil contamination associated with this smelter material can be reliably contained (USEPA, 2008). For purposes of the RD, waste materials that cannot be sampled can be identified by a visual standard. As such, any visible waste material associated with the historical smelter operation will be addressed during the remedial action (RA) for the TFM Site. A summary of the RAOs for the TFM Site are provided in the following paragraphs: On-Site Soil and Waste Materials: Protect human health by preventing direct contact, through the ingestion or inhalation exposure pathways with arsenic, cadmium, and lead contaminated on-site soil and waste material by reducing arsenic, cadmium, and lead concentrations to residential levels less than 37 milligrams per kilogram (mg/kg), 75 mg/kg, and 500 mg/kg, or to nonresidential levels less than 200 mg/kg, 560 mg/kg, and 1,000 mg/kg, respectively. In addition to numerical cleanup levels, visible waste associated with the historical smelter operation will be addressed during the RA for the TFM Site (USEPA, 2008). Sediment: Protect human health and the environment by preventing direct contact, through the ingestion pathway, with arsenic, cadmium, and lead contaminated sediment by reducing arsenic, cadmium, and lead concentrations to levels less than 181 mg/kg, 813 mg/kg, and 500 mg/kg, respectively (USEPA, 2008).

Table 2-1 presents the RAO criteria that were developed for the TFM Site. The discussion in Sections 3.0 through 7.0 includes a comparison of sample results to these RAO criteria. Constituents that exceed RAO criteria are highlighted in the data summary tables for each section. * * * * Remedial Design Data Evaluation Report On-Site Soil and Waste Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_03_Final.doc 3-1 03/04/2013 3.0 ON-SITE SOIL AND WASTE 3.1 TOPOGRAPHIC SURVEY A topographic survey of the entire TFM Site was conducted to develop the base map for the RD, including the adjacent area south of the Strip Mine Pit. The survey has one-foot contours and is accurate to 0.05 ft on state plane coordinates. Ground surface elevations were established to within a minimum 0.01 vertical ft (above mean sea level [msl]) relative to an established United States Geological Survey (USGS) benchmark. The survey captured tops and bottoms of all slopes and all other breaklines. Property lines and utilities were also included in the survey. The base map for the RD is presented in Appendix A. Surveying services were provided by L.W. Survey Company of Tulsa, Oklahoma. 3.2 VISUAL WASTE SURVEY FINDINGS A visual waste survey was conducted to determine the extent of waste material outside of the former production area. Smaller areas of waste material exist on the TFM Site as driveway/road materials, in drainage channels, and discontinuous “waste pockets”. The visual waste survey was conducted by walking a grid pattern in larger areas, and individual transects for smaller areas. Where waste was identified, soil samples were collected to determine the extent of impacted soil prior to placing it in the consolidation cell. In conjunction with the visual survey, visual pits or trenches were dug in areas determined by field personnel during the RD field investigation activities to more narrowly define the vertical extent of waste materials. A total of 29 visual pits were completed. Figure 3-1 presents the locations of the visual pits (identified by a “VP” designator), and Table 3-1 summarizes the locations and waste depths. Visual pit profiles are presented in Appendix B and visual pit photographs are presented in Appendix C. Locations of waste materials identified outside of the delineated waste area were mapped to document all visible waste materials for future incorporation within the consolidation cell. Figure 3-2 presents the estimated depths of waste, as well as depicting the isolated waste areas outside of the former production area. Northwest Portion of TFM Site An area of waste in the northwest corner of the TFM Site was identified during the visual survey and further delineated with seven visual pits (VP-56 to VP-61). Analytical samples were collected at three locations (TR-42, TR-43, and TR-44), which are outlined on Table 3-2. The waste was isolated to a small area around TR-42 and extended approximately 0.5 ft deep. The waste was also present to an approximate depth of 1.0 ft deep in the area of TR-44, and this material extended south to the access Remedial Design Data Evaluation Report On-Site Soil and Waste Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_03_Final.doc 3-2 03/04/2013 road/driveway, including the drainage embankment. The two identified waste areas at TR-42 and TR-44 are isolated and do not connect to each other. An isolated waste area was also identified starting at the drainage embankment south of the access road/driveway at VP-62 and extended to TR-45. The waste was approximately 4.0 ft deep along the west bank of the drainage ditch, and samples were collected at TR-45. The isolated waste areas are depicted on Figure 3-2, and analytical results for TR-42, TR-43, TR- 44, and TR-45 are discussed further in Section 3.3.3 and summarized in Table 3-3. Western Portion of TFM Site The western portion of the TFM Site had three isolated areas of waste that were identified during the RD field investigation activities that are outside of the delineated waste area. These areas were identified as follows: An old road bed appears to be present going off the TFM Site at TR-40. An isolated area of waste approximately 0.5 to 1.0 ft deep was delineated and samples were collected at TR-40, TR- 50, TR-51, and TR-52 as outlined on Table 3-2. An additional isolated waste area was identified west of the residence on the west side of the access road/driveway. The area was delineated based up on observations from VP-63, VP-64, VP-65, and TR-48. The waste in this area was approximately 1.0 ft deep. Lastly, an isolated area of fine grained waste was identified in the area of TR-49. The fine grained waste was visible on the surface and present to a depth of 0.5 ft. Samples were collected from TR-49 as outlined in Table 3-2. The isolated waste areas are depicted on Figure 3-2, and analytical results for TR-40 and TR-49 through TR-52 are discussed further in Section 3.3.3 and summarized in Table 3-3. TFM Ponds During the RD field investigation activities visual pits were also completed within the defined waste area to evaluate various hills and piles of debris. Eight visual pits (VP-42 through VP-49) were completed on and near the banks of Ponds 2 and 3. Retorts line the inside and outside banks of both Pond 2 and Pond 3. Broken retorts and waste fill the space between the outside and inside retort linings of the pond banks. Waste was identified to 7.0 ft deep at VP-46, and this waste depth varied based upon depth of pond bank compared to original ground surface prior to pond construction. The visual pit locations are presented on Figure 3-1, and waste depths are summarized in Table 3-1. Remedial Design Data Evaluation Report On-Site Soil and Waste Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_03_Final.doc 3-3 03/04/2013 Mid-Site Ravine A bank is present that runs along the south side of the Mid-Site Ravine from the west side of the TFM Site approximately 900 ft to the east. Three visual pits were dug along the Mid-Site Ravine bank (VP-68 through VP-70). VP-68 and VP-70 contained waste to 5.0 ft deep, and no waste was encountered at VP- 69. Strip Mine Pit A large mound is present along the northeast corner of the Strip Mine Pit, and this mound is believed to be a result of strip mining activities. Three visual pits were completed (VP-51, VP-52, and VP-53). The south end of the mound (VP-51) consisted of a shale/coal mix. Waste was only present on the surface of the middle visual pit (VP-53), and waste was present to 4.5 ft deep at the north end of the mound (VP-52). Three visual pits were also dug along the north bank of the Strip Mine Pit (VP-50, VP-54, and VP-55). Waste was present to 1.0 ft deep on the eastern portion of the bank (VP-50), and only limited pieces of waste were present in the middle and western portion of the bank (VP-54 and VP-55). The visual pit locations are presented on Figure 3-1, and waste depths are summarized in Table 3-1. Based upon the collective visual observations from the RI and RD, depths of waste on the TFM Site were estimated and are presented in Figure 3-2. Visual observations include recorded waste depths from trenching activities for visual and analytical purposes. The isolated waste areas and estimated depth of waste are also presented on Figure 3-2. The volume of waste observed during RI and RD field activities was approximately 146,000 cubic yards (cy), and this volume will be verified during the remedial design. 3.3 SOIL SAMPLING FOR WASTE CHARACTERIZATION Surface and subsurface soil samples were collected from within the waste material area, the perimeter of the waste material area, and in isolated areas of waste. Samples were submitted to the Oklahoma State Environmental Lab (SEL) for off-site laboratory analysis of total arsenic, cadmium, and lead and Toxicity Characteristic Leaching Procedure (TCLP) arsenic, cadmium, and lead (Table 3-2 through Table 3-4). The intent of the sampling was to determine the vertical and horizontal extent of metals in excess of RAOs and to determine if the soil exhibited TCLP metals results above regulatory criteria. Surface and subsurface soil samples were collected as indicated on Table 3-2. All samples were collected using trenching techniques; however, samples of the large waste fragments were not collected. Sample collection began at the soil interface below the waste to determine the extent to which leaching had occurred into the native clay. One sample of the fine waste/soil matrix within the larger waste fragments was collected at TR-24, to further characterize these materials. Remedial Design Data Evaluation Report On-Site Soil and Waste Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_03_Final.doc 3-4 03/04/2013 Surface and subsurface soil analytical data from the RD were combined with the RI analytical data and compared against the RAOs for the TFM Site. Figures 3-3 through 3-5 present the combined RD and RI soil results compared to the RAOs at the respective sample depths (0 to 0.5 ft below ground surface [bgs], 0.5 to 2.0 ft bgs, and 2.0 to 4.0 ft bgs). Complete laboratory analytical data packages are presented in Appendix D. The approximate volume of soil exceeding RAOs for each depth interval is indicated below, and these estimates will be verified during the remedial design: Approximate Volume of Soil > RAOs Depth (ft bgs) Volume of soil > Non-Residential RAO (cy) Volume of soil < Non-Residential RAO and > Residential RAO (cy) 0 – 0.5 26,000 6,500 0.5 - 2 61,000 750 2 - 4 40,000 0 Total 127,000 7,250 Note: As evident on Figures 3-2 through 3-5, the majority of soil with RAO exceedances is co-located with visually observed waste. Based on this overlap, the soil volume estimates provided here should not be considered additive to the waste volume estimates provided in Section3.2. 3.3.1 Waste Material Area Results In the waste material area (Figure 3-1), soil samples were collected from the native clay under the waste to assess any apparent leaching of materials from the waste into the subsurface. Test pits were completed at six sample locations (TR-22 through TR-27) and analyzed for TCLP arsenic, cadmium, and lead. One sample of the fine waste/soil material within the matrix of the large waste material was collected from the 0 to 1.0 ft bgs interval at TR-24. A sample collection summary is presented in Table 3-2, and analytical results are presented in Table 3-4. Sample locations are presented on Figure 3-1, and trench diagrams including descriptions of the waste and thickness of the waste are presented in Appendix B and Appendix C. Waste materials present in the test pits ranged from fine grained waste down to 0.5 ft bgs to large pieces of broken retorts down to 5.0 ft bgs (Figure 3-2). The sample of fine grained material collected from the matrix of the large waste material from 0 to 1.0 ft bgs at TR-24 exceeded the TCLP criteria for cadmium and lead. All samples (TR-22 through TR-27) collected from the native clay under the waste were below the TCLP criteria. TCLP arsenic was not detected in any samples, TCLP cadmium was detected in two samples of native clay (TR-22 and TR-25), and TCLP lead was detected in one sample of native clay Remedial Design Data Evaluation Report On-Site Soil and Waste Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_03_Final.doc 3-5 03/04/2013 (TR-25). Based on the RI and RD data sets, leaching of metals into the native clay does not appear to be occurring. 3.3.2 Perimeter of Waste Material Area Results Soil samples were collected along the perimeter of the waste material area (Figure 3-1) to further characterize the horizontal and vertical extent of the waste material area. Soil samples were collected from the soil under the deepest occurrence of waste material to assess any apparent leaching of materials from the waste into the subsurface. If present, fine grained waste materials that had the appearance of soil were collected for characterization. Test pits were completed at twelve locations (TR-28 through TR-36, and TR-46 through TR-48) and analyzed for total arsenic, cadmium, and lead; and TCLP arsenic, cadmium, and lead. A sample collection summary is presented in Table 3-2, and analytical results are presented in Tables 3-3 and 3-4. Sample locations are presented on Figure 3-1, and trench diagrams including descriptions of the waste and thickness of the waste are presented in Appendix B and Appendix C. Waste materials were present at four test pit locations (TR-28, TR-29, TR-32, and TR-48) and ranged from 1.0 to 2.0 ft bgs in depth. No TCLP or RAO exceedances were noted in the sample intervals collected below the observed waste at TR-28, TR-29, TR-32, and TR-48. The following samples exhibited exeedances of TCLP criteria and/or RAOs: TR-30: A sample collected from 0 to 1.0 ft bgs at TR-30 exceeded the TCLP criteria for cadmium and lead, the residential and nonresidential RAOs for total cadmium and lead, and the residential RAO for arsenic. No TCLP or RAO exceedances occurred in the 1.0 to 3.0 ft bgs sample interval for TR-30. TR-34: The sample collected from the 0 to 0.5 ft bgs interval at TR-34 exceeded residential and nonresidential RAO for lead in both the primary sample and field duplicate. In addition, the field duplicate (TR-2002/SS02) collected from the 0 to 0.5 ft bgs interval at TR-34 exceeded the residential RAO for arsenic. No exceedances of the TCLP criteria were noted in the sample collected from 0 to 0.5 ft bgs. No exceedances of TCLP criteria or RAOs were noted in the 2.0 to 3.5 ft bgs sample interval for TR-34. TR-46: The sample collected from the 0 to 0.5 ft bgs interval at TR-46 exceeded the residential RAO for lead, and the sample collected from the 0.5 to 1.5 ft bgs interval exceeded the residential RAO for arsenic. No exceedances of TCLP criteria or RAOs were noted in the 1.5 to 3.0 ft bgs Remedial Design Data Evaluation Report On-Site Soil and Waste Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_03_Final.doc 3-6 03/04/2013 sample interval for TR-46. TR-47: A sample collected from 0 to 0.5 ft bgs interval at TR-47 exceeded the residential RAO for lead. No exceedances of the TCLP criteria or RAOs were noted in the 0.5 to 1.5 ft bgs and 1.5 to 4.0 ft bgs intervals. No other RAO or TCLP exceedances were noted for the samples designated as the perimeter of the waste area. 3.3.3 Isolated Waste Material Areas Results During the visual waste survey smaller areas of waste material were identified onsite as driveway/road materials, in drainage channels, and discontinuous “waste pockets”. Soil samples were collected from the soil under the deepest occurrence of waste material, and if present, fine waste materials that have the appearance of soil were collected for characterization. A total of 16 locations (TR-37 through TR-45 and TR-49 through TR-55) were sampled based upon visual survey findings and analyzed for total arsenic, cadmium, and lead; and TCLP arsenic, cadmium, and lead. A sample collection summary is presented in Table 3-2, and analytical results are presented in Tables 3-3 and 3-4. Sample locations are presented on Figure 3-1, and trench diagrams including descriptions of the waste and thickness of the waste are presented in Appendix B and Appendix C. Northwest Portion of TFM Site Analytical samples were collected at three locations (TR-42, TR-43, and TR-44) in the northwest corner of the TFM property identified during the visual survey. The waste is isolated to a small area around TR- 42 approximately 0.5 ft deep. In addition, the waste is present to an approximate depth of 1.0 ft deep in the area of TR-44, which extends south to the road and includes the drainage embankment. No TCLP or RAO exceedances were noted in the sample intervals collected below the observed waste at TR-42 and TR-44, or in the sample intervals collected at TR-43. An isolated waste area was also identified starting at the drainage embankment south of the road extending to TR-45. A sample was collected from the native clay below the waste, which was approximately 4.0 ft deep along the west bank of the drainage ditch. No exceedances of TCLP or RAOs were noted. Western Portion of TFM Site The western portion of the TFM site had two isolated areas of waste that were identified during the RD field activities that are outside of the delineated waste area. Remedial Design Data Evaluation Report On-Site Soil and Waste Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_03_Final.doc 3-7 03/04/2013 An old road bed appears to be present going off the site at TR-40. An isolated area of waste approximately 0.5 to1.0 ft deep was delineated and samples were collected at TR-40, TR-50, TR- 51, and TR-52. An exceedance of the residential RAO for cadmium was noted in the 0 to 0.5 ft bgs interval at TR-50, and this sample also exhibited an exceedance of the TCLP criteria for cadmium. No exceedances of RAOs or TCLP criteria were noted in samples collected below 0.5 ft bgs at TR-50. In addition, an exceedance of the residential RAO for lead was noted in the 0 to 0.5 ft bgs interval at TR-52, but not in samples collected below 0.5 ft bgs at this location. No other exceedances were noted of RAOs or TCLP criteria for samples collected in this area. An additional isolated waste area was also identified west of the residence on the west side of the road. An isolated area of fine grained waste was identified in the area of TR-49. No exceedances of RAOs or TCLP criteria were noted in samples collected from TR-49. Access Road/Driveway TR-37, TR-38, and TR-39 were collected along the access road to define vertical extent of waste along the road. Waste was present to 1.5 ft bgs at TR-37 and 1.0 ft bgs at TR-38. The residential RAO of cadmium was exceeded at the 1.5 to 2.0 ft bgs interval at TR-37. No exceedances were noted in the subsequent sample intervals at TR-37. No exceedances of RAOs or TCLP criteria were noted for samples collected from TR-38 and TR-39. 3.4 POTENTIAL BORROW MATERIALS SOIL SAMPLING AND DATA COLLECTION Soil samples were collected from seven test pits (TP-01 through TP-07) to evaluate the potential for on-site materials to be used as a borrow source for consolidation cell cap materials. ODEQ will review and approve the sample data and proposed borrow source locations before the borrow soil is removed and used. Test pit locations are presented on Figure 3-1. A sample summary is presented on Table 3-5, and analytical results are presented on Table 3-6. Trench/test pit diagrams including descriptions of the waste and thickness of the waste are presented in Appendix B. Soil samples were collected from below the root zone, or below waste materials if present, to 5.0 ft bgs. Samples were initially analyzed by SEL for total arsenic, cadmium, and lead. When these results were below the residential RAO for soil, additional soil samples were collected and submitted to SEL for further chemical evaluation for the presence of volatile organic compounds (VOCs), semivolatile organic compounds (SVOCs), Resource Conservation and Recovery Act (RCRA) Metals, pesticides, polychlorinated biphenyls (PCBs), and herbicides. Remedial Design Data Evaluation Report On-Site Soil and Waste Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_03_Final.doc 3-8 03/04/2013 Test pits were also used to collect disturbed geotechnical samples, and borings were used to collect undisturbed geotechnical samples. Samples were collected from below the root horizon to 5 ft bgs. Samples were submitted to a geotechnical laboratory (Standard Testing and Engineering Company in Tulsa, Oklahoma) for off-site analysis of Atterberg limits, sieve with hydrometer, specific water/moisture content, standard proctor, and modified proctor, which need to be performed on disturbed samples. Soil samples were also collected using Shelby tubes advanced using hollow stem augers (HSAs) to provide geologic information for logging and samples for geotechnical analysis for hydraulic conductivity and soil bulk density analyses, which need to be performed on undisturbed samples. Geotechnical data is presented in Appendix E, and will be discussed and evaluated during the Remedial Design Report. Soil samples were also collected and submitted to the Tulsa County Oklahoma State University Extension office for analysis of pH and N-P-K to determine fertility needs for maximum growing effectiveness. Soil fertility results are presented in Appendix E, and will be discussed and evaluated during the Remedial Design Report. A borrow material sample summary is presented in Table 3-5. Waste materials were not observed at TP-01 to TP-06; however, waste material was observed to 1.0 ft bgs at TP-07 (Figure 3-1). Borrow material samples were collected below the waste at TP-07 from the 1.0 to 5.0 ft bgs interval. The initial total arsenic, cadmium, and lead results were below the residential RAO for all test pit locations, and then screened against the borrow material values (arsenic – 20 mg/kg, cadmium – 20 mg/kg, and lead – 100 mg/kg) set forth by ODEQ. With the exception of arsenic, cadmium, and lead, results for the additional chemical parameters were screened using the residential soil values from the USEPA Regional Screening Level (RSL) Summary Table (USEPA, 2012). All RCRA metal detections (with the exception of lead in TP-06) were below the borrow material screening values or applicable residential soil RSLs for all test pit locations. No detections of VOC, SVOC, pesticide, PCB, or herbicide analytes were present in any samples collected from the seven test pits TP-01 to TP-07. Figure 3-6 presents potential borrow material areas located on the TFM Site. It is assumed that the root zone (0 to 0.5 ft bgs) will be removed prior to any borrow material excavation; therefore, Figure 3-6 is based upon collective analytical data from the 0.5 – 5.0 ft bgs interval from locations collected during the RI and RD. Based upon the potential borrow material areas depicted in Figure 3-6, and a depth of 0.5 to 5.0 ft bgs the volume of available borrow material is approximately 128,000 cy. * * * * * Remedial Design Data Evaluation Report Off-Site Soil and Waste Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_04_Final.doc 4-1 03/04/2013 4.0 OFF-SITE SOIL AND WASTE 4.1 VISUAL WASTE SURVEY FINDINGS Waste material has been observed to extend off-site to adjacent properties. Per the RD Work Plan, a visual waste survey was planned for all properties adjacent to the TFM Site. This visual survey was to be conducted by walking a 25 to 50 ft buffer zone around the perimeter of the TFM Site to identify areas where waste materials extended to off-site adjacent properties. However, due to access limitations the off-site visual survey could not be performed as outlined. For all areas, except the properties south of the Strip Mine Pit, the visual survey was performed by making observations from the TFM Site. Based on these observations, the following areas of apparent waste materials on adjacent properties were noted (See also Figure 4-1: Old roadbeds appear to be leaving the TFM site in the western portion of the property in a northwestern direction onto the adjacent Moore property. Another former road appears to be leaving the TFM site in the northwest portion of the TFM site in a northern direction onto the adjacent Faith Assembly Church Property. The TFM Site is bounded immediately to the east by the Atchison Topeka Santa Fe railroad tracks, currently owned and operated WATCO. An access agreement is not in place for this property and was not pursued for RD activities. Waste fragments were visually observed on the railroad property southeast of the Strip Mine Pit, as well as, an area approximately 100 ft in length southeast of Pond 1. A visual survey of the ridge south of the Strip Mine Pit was attempted from the west, but due to thick vegetation access was limited. A visual survey of the ridge south of the Strip Mine Pit was then conducted from a boat, and where possible, the ridge was traversed by foot. Waste material was observed on the surface in several areas of the ridge, and three samples were collected along the ridge (OSL-120 through OSL-122). Based upon the visual survey and analytical results from these samples, further investigation of the ridge south of the Strip Mine Pit was deemed necessary. On July 9 through July 12, 2012, clearing and grubbing activities occurred along the ridge south of the Strip Mine Pit, starting at the west area of the Strip Mine Pit to the eastern point of the ridge. Once clearing activities were completed a visual survey of the ridge was conducted. Small fragments of waste material were sporadically observed along the ridge and slopes and appeared only to be present on the Remedial Design Data Evaluation Report Off-Site Soil and Waste Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_04_Final.doc 4-2 03/04/2013 surface. Test pits were dug along the ridge (Figure 4-2, locations OSL-123 through OSL-131) and samples were collected and submitted to the SEL for off-site laboratory analysis of total arsenic, cadmium, and lead and TCLP arsenic, cadmium, and lead (Table 4-1). The adjacent property south of the north-south section of the Strip Mine Pit was also included in the off-site visual survey. An isolated waste area was identified and delineated (Figure 4-1). Test pits OSL-132 and OSL-133 were placed within this waste area to determine the vertical extent of waste, and samples were collected and submitted to the SEL for off-site laboratory analysis of total arsenic, cadmium, and lead and TCLP arsenic, cadmium, and lead (Table 4-1). 4.2 SOIL SAMPLING AND ANALYTICAL RESULTS Surface and subsurface soil samples were collected to further define off-site materials and the extent of impacted soil. All samples were collected using trenching techniques. Samples were collected from the 0 to 0.5 ft bgs, 0.5 to 2.0 ft bgs, and 2.0 to 4.0 ft bgs intervals, and analyzed for total arsenic, cadmium, and lead; and TCLP arsenic, cadmium, and lead. A sample collection summary is presented in Table 4-1, and analytical results are presented in Tables 4-2 through 4-4. Complete laboratory analytical data packages are presented in Appendix D. Sample locations are presented on Figure 4-2, and trench diagrams including descriptions of the waste and thickness of the waste are presented in Appendix B and Appendix C. Surface and subsurface soil analytical data from off-site were compared against the RAOs for the TFM Site. Figures 4-3 through 4-5 present the RD soil results compared to the RAOs at the respective sample depths (0 to 0.5 ft bgs, 0.5 to 2.0 ft bgs, and 2.0 to 4.0 ft bgs). The approximate volume of soil exceeding RAOs for each depth interval was in indiciated below, and these estimates will be verified during the remedial design: Approximate Volume of Soil > RAOs Depth (ft bgs) Volume of soil > Non-Residential RAO (cy) Volume of soil < Non-Residential RAO and > Residential RAO (cy) 0 to 0.5 630 390 0.5 to 2 1,700 1,800 2 to 4 2,000 380 Total 4,330 2,570 Note: As indicated on Figure 4-3, it was assumed that the impacted area included the entire first ridgeline that was south of the Strip Mine Pit. Based on the sporadic nature of the observed waste, the volume of impacted material presented here may be overestimated. Remedial Design Data Evaluation Report Off-Site Soil and Waste Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_04_Final.doc 4-3 03/04/2013 Initial Survey – South Ridge of Strip Mine Pit During the initial visual survey of the ridge south of the Strip Mine Pit, three sample locations (OSL-120, OSL-121, and OSL-122) were identified and samples were collected at three depth intervals. Results for samples collected from OSL-120 and OSL-121 were below the site-specific RAOs and TCLP criteria. Total lead results for the 0.5 to 1 ft bgs and 1 to 2.5 ft bgs intervals at location OSL-122 exceeded the residential and non-residential RAO. Additional Survey – South Ridge of Strip Mine Pit Based upon the sample results for the initial survey, further characterization of the ridge was deemed necessary. This characterization required clearing vegetation from the west end of the Strip Mine Pit along the ridge until it ended at its furthest east point, which intersects the north-south portion of the Strip Mine Pit. Once the clearing was completed, nine test pits were advanced into the initial ridge south of the Strip Mine Pit (OSL-123 through OSL-131). The test pits were located at the approximate locations of the Strip Mine Pit sediment sampling transects (See Section 5.0). Exceedances of the residential and/or non-residential RAOs for arsenic were noted for one sample in the 0 to 0.5 ft bgs interval (OSL-123), one sample in the 0.5 to 2 ft bgs interval (OSL-128), and three samples in the 2 to 4 ft bgs interval (OSL-125, OSL-127, and OSL-128). No exceedance of the RAOs was noted for cadmium. Exceedances of the residential and/or non-residential RAOs for lead were noted for three samples in the 0 to 0.5 ft bgs interval (OSL-125, OSL-127, and OSL-128), four samples in the 0.5 to 2 ft bgs interval (OSL-125, OSL- 126, OSL-127, and OSL-128), and three samples in the 2 to 4 ft bgs interval (OSL-125, OSL-126, and OSL-127). None of the TCLP results exceeded the TCLP criteria. Samples with exceedances were primarily located directly south of the former operations area of the TFM Site. Additional samples were collected from the 0 to 5 ft bgs interval at locations OSL-128 and OSL-131 to evaluate the potential to use soil from these locations as borrow material for the consolidation cell cap. The samples were submitted to SEL for analysis of VOCs, SVOCs, RCRA metals, pesticides, PCBs, and herbicides. The total arsenic, cadmium, and lead results were screened against the borrow material values (arsenic – 20 mg/kg, cadmium – 20 mg/kg, and lead – 100 mg/kg) set forth by ODEQ. With the exception of arsenic, cadmium, and lead, results for the additional chemical parameters were screened using the residential soil values from the USEPA RSL Summary Table (USEPA, 2012). All RCRA metal detections (with the exception of lead in OSL-128 and OSL-131) were below the site-specific RAOs or applicable residential soil RSLs. No detections of VOC, SVOC, pesticide, PCB, or herbicide analytes were present. Remedial Design Data Evaluation Report Off-Site Soil and Waste Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_04_Final.doc 4-4 03/04/2013 Isolated Waste Area – Southern Area of Strip Mine Pit An isolated waste area was identified on the adjacent property south of the north-south section of the Strip Mine Pit (Figure 4-1). Two test pits (OSL-132 and OSL-133) were located within this waste area to determine the vertical extent of waste and define the extent of impacted soil. Waste was present to 2 ft bgs at OSL-132, and present on the surface of OSL-133. An additional visual pit was dug between OSL- 132 and OSL-133, in which waste was present to 2 ft bgs. Based upon the visual observations from the RD, the volume of waste observed at the isolated waste area was approximately 1,200 cy, and this volume will be verified during the remedial design. The result for the sample collected from the 0 to 2 ft bgs interval at OSL-132 exceeded both the residential and non-residential RAO for lead. Exceedances of the residential RAO for arsenic were noted in the 0 to 0.5 ft bgs and 0.5 to 2 ft bgs interval at location OSL-133. No exceedances were noted of the TCLP criteria in these samples. * * * * * Remedial Design Data Evaluation Report Sediment Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_05_Final.doc 5-1 03/04/2013 5.0 SEDIMENT 5.1 SEDIMENT SAMPLING AND DATA COLLECTION During the RD field activities, sediment samples were collected to determine vertical extent of sediment contamination prior to placement in the consolidation cell. Samples were collected from TFM Pond 1, TFM Pond 2, TFM Pond 3, TFM Pond 4, the Mid-Site Ravine, and the Strip Mine Pit as indicated on Table 5-1. Sediment sampling locations are presented on Figure 5-1. TFM Ponds and Mid-Site Ravine Samples were collected from the 0 to 0.5 ft bgs interval from TFM Pond 1, TFM Pond 2, TFM Pond 3, TFM Pond 4, TFM Pond 5, and the Mid-Site Ravine during the RI for analysis of total arsenic, cadmium, lead, and zinc. The results from the RI indicated that metals results in excess of the site-specific sediment RAOs for arsenic, cadmium, and/or lead were encountered in the 0 to 0.5 ft bgs interval of TFM Pond 1, TFM Pond 2, TFM Pond 3, TFM Pond 4, and the Mid Site Ravine. Therefore, during the RD, additional samples were collected for analysis of arsenic, cadmium, and lead to further determine the vertical extent of contamination. In particular, samples were collected from the 0.5 to 1 ft bgs interval at TFM Pond 1 and TFM Pond 2, and samples were collected from the 0.5 to 1 ft bgs and 1 to 2 ft bgs intervals at TFM Pond 3, TFM Pond 4, and the Mid-Site Ravine. The sampling plan outlined in the FSP outlined collection of samples from both the 0.5 to 1 ft bgs and 1 to 2 ft bgs interval at each location. In several instances sediment samples were only collected 0.5 to 1.0 ft bgs interval due to encountering native material beneath the sediment shallower than 1.0 ft bgs. In such cases, the deepest sample was collected from the native materials beneath the sediment. Samples were also collected from one depth (0 to 0.5 ft bgs) at each location for analysis of TCLP arsenic, cadmium, and lead. Strip Mine Pit Samples were collected from the 0 to 0.5 ft bgs interval from the mid-section of the Strip Mine Pit during the RI, and none of the results exceeded site-specific RAOs for sediment. During the RD, sediment cores were collected from the Strip Mine Pit along transect lines at various distances from the shore (transect lines are illustrated on Figure 5-1) to characterize the extent of smelter materials slumping into the Strip Mine Pit. The cores were visually inspected for the presence of waste materials. Sample locations and depths were determined based on visual inspection of the cores. Results of the visual waste inspection of the Strip Mine Pit are presented on Table 5-2, and the estimated depths of waste are illustrated in Figure 5-2. Fine grained waste was observed predominantly on the north bank of the Strip Mine Pit and also on the east and west banks of the northern section. Waste was only observed in the 0 to 0.5 ft bgs interval. Remedial Design Data Evaluation Report Sediment Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_05_Final.doc 5-2 03/04/2013 Samples were collected from up to three depths at nine locations for analysis of total arsenic, cadmium, and lead to determine vertical extent of contamination. One sample was also collected at each location for analysis of TCLP arsenic, cadmium, and lead. 5.2 SEDIMENT RESULTS Analytical results for the RD data collection are provided on Tables 5-3 and 5-4. Complete laboratory analytical data packages are presented in Appendix D. Analytical sediment data from the RD were combined with the RI analytical data and compared against the RAOs and TCLP criteria for the TFM Site. Figures 5-3 through 5-5 present the combined RD and RI sediment results compared to the RAOs and TCLP criteria at the respective sample depths (0 to 0.5 ft bgs, 0.5 to 2.0 ft bgs, and 2.0 to 4.0 ft bgs). 5.2.1 TFM Pond 1 Results Sediment samples were collected from five locations in TFM Pond 1 during RD field activities. Two samples were collected from each location (0 to 0.5 ft bgs and 0.5 to 1.0 ft bgs). Samples collected from the 0 to 0.5 ft bgs interval were analyzed for TCLP arsenic, cadmium, and lead. Samples collected from the 0.5 to 1.0 ft bgs interval were analyzed for total arsenic, cadmium, and lead to determine the vertical extent of contamination. Native clay was uniformly observed at approximately 0.5 ft bgs at all sample locations in TFM Pond 1. The results from the RI indicated that metals results in excess of the site-specific sediment RAOs for arsenic, cadmium, and/or lead were encountered in the 0 to 0.5 ft bgs interval at TFM Pond 1. During the RD, one sample and its duplicate collected from 0.5 to 1 ft bgs at location PD1-05 had lead results in excess of the RAO. In addition, two samples had reporting limits for lead in excess of the RAO. One sample from the 0 to 0.5 ft bgs interval was submitted for analysis of TCLP arsenic, cadmium, and lead during the RI, and results for this sample were below the TCLP criteria. Five additional samples from the 0 to 0.5 ft bgs interval were submitted for TCLP analysis during the RD. The TCLP cadmium result from location PD1-04 (1.07 mg/L) slightly exceeded the 1 mg/L TCLP criteria. TFM Pond 1 is approximately 1.22 acres. Samples with metal results in excess of RAOs for sediment were encountered in both the 0 to 0.5 and 0.5 to 1 ft bgs intervals across TFM Pond 1. Assuming the depth of contamination is relatively uniform, the depth of contaminated sediment is approximately 1 ft deep. Therefore, approximately 1,970 cy of sediment above RAOs is estimated in TFM Pond 1 for inclusion in the consolidation cell. Only one location exhibited a minor exceedance of the TCLP criteria Remedial Design Data Evaluation Report Sediment Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_05_Final.doc 5-3 03/04/2013 at a depth of 0 to 0.5 ft bgs. Assuming that less than 10 percent of the TFM Pond 1 sediment exceeds TCLP criteria, approximately 100 cy of sediment is above the TCLP criteria. 5.2.2 TFM Pond 2 Results Sediment samples were collected from four locations in TFM Pond 2 during RD field activities. Two samples were collected from each location (0 to 0.5 ft bgs and 0.5 to 1.0 ft bgs). Samples collected from the 0 to 0.5 ft bgs interval were analyzed for TCLP arsenic, cadmium, and lead. Samples collected from the 0.5 to 1.0 ft bgs interval were analyzed for total arsenic, cadmium, and lead to determine vertical extent of contamination. Native clay was uniformly observed at approximately 0.5 ft bgs at all sample locations in TFM Pond 2. The results from the RI indicated that metals results in excess of the site-specific sediment RAOs for lead were encountered in the 0 to 0.5 ft bgs interval at TFM Pond 2. During the RD, three of the four sample locations (PD2-03, PD2-04, and PD2-06) had results that exceeded the residential/nonresidential RAO for lead in the 0.5 to 1.0 ft bgs interval. No exceedances of TCLP criteria or any additional RAO exceedances were noted in the sediment samples collected from TFM Pond 2 during RD activities. TFM Pond 2 is approximately 0.85 acres. Samples with metal results in excess of RAOs for sediment were encountered in both the 0 to 0.5 and 0.5 to 1 ft bgs intervals across TFM Pond 2. Assuming the depth of contamination is relatively uniform, the depth of contaminated sediment is approximately 1 ft deep. Therefore, approximately 1,370 cy of sediment above RAOs is estimated in TFM Pond 2 for inclusion in the consolidation cell. 5.2.3 TFM Pond 3 Results Sediment samples were collected from four locations in TFM Pond 3 during RD field activities. Samples were collected from three depth intervals (0 to 0.5 ft bgs, 0.5 to 1.0 ft bgs, and 1.0 to 2.0 ft bgs) at PD3-03 and PD3-05, and samples were collected at two intervals (0 to 0.5 ft bgs and 0.5 to 1.0 ft bgs) at PD3-04 and PD3-06. Samples collected from the 0 to 0.5 ft bgs interval were analyzed for TCLP arsenic, cadmium, and lead. Samples collected from the 0.5 to 1.0 ft bgs and 1.0 to 2.0 ft bgs intervals were analyzed for total arsenic, cadmium, and lead to determine vertical extent of contamination. Native clay was observed at approximately 0.5 ft bgs at PD3-04 and PD3-06, which were located in the deeper portions of TFM Pond 3. Native clay was observed at approximately 1.0 ft bgs at PD3-03 and PD3-05, which were located near the shoreline of TFM Pond 3. The results from the RI indicated that metals results in excess of the site-specific sediment RAOs for lead Remedial Design Data Evaluation Report Sediment Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_05_Final.doc 5-4 03/04/2013 were encountered in the 0 to 0.5 ft bgs interval at TFM Pond 3. During the RD, three of the four sample locations (PD3-03, PD3-05, and PD3-06) had results or an analytical reporting limit that exceeded the residential/nonresidential RAO for lead in the 0.5 to 1.0 ft bgs interval. In addition, the lead result for the 1 to 2 ft bgs interval at location PD3-03 exceeded the sediment RAO. No exceedances of the TCLP criteria were present at the 0 to 0.5 ft bgs interval in TFM Pond 3. TFM Pond 3 is approximately 0.70 acres. Samples with metal results in excess of RAOs for sediment were encountered to 1 ft bgs across Pond 3, and a limited area in the vicinity of the shoreline at PD3-03 had metals results in excess of RAOs to 2 ft bgs. Assuming the depth of contamination of approximately 1 ft bgs across the pond and an area approximately 10 percent of the pond contaminated to 2 ft bgs, approximately 1,240 cy of sediment above RAOs is estimated in TFM Pond 3 for inclusion in the consolidation cell. 5.2.4 TFM Pond 4 Results Sediment samples were collected from two locations in TFM Pond 4 during RD field activities. Three samples were collected from each location (0 to 0.5 ft bgs, 0.5 to 1.0 ft bgs, 1.0 to 2.0 ft bgs). Samples collected from the 0 to 0.5 ft bgs interval were analyzed for TCLP arsenic, cadmium, and lead. Samples collected from the 0.5 to 1.0 ft bgs and 1.0 to 2.0 ft bgs intervals were analyzed for total arsenic, cadmium, and lead to determine vertical extent of contamination. Native clay was observed at approximately 1.0 ft bgs at both sample locations. The results from the RI indicated that metals results in excess of the site-specific sediment RAOs for lead were encountered in the 0 to 0.5 ft bgs interval at TFM Pond 4. During the RD, both sample locations (PD4-02 and PD4-03) had results that exceeded the residential/nonresidential RAO for lead in the 0.5 to 1.0 ft bgs and 1 to 2 ft bgs depth intervals. No exceedances of the TCLP criteria were present at the 0 to 0.5 ft bgs interval in TFM Pond 4. TFM Pond 4 is approximately 0.08 acres. Samples with metal results in excess of RAOs for sediment were encountered to approximately 2 ft bgs across TFM Pond 4. Approximately 260 cy of sediment above RAOs is estimated in TFM Pond 4 for inclusion in the consolidation cell. 5.2.5 TFM Pond 5 Results One sediment sample was collected from TFM Pond 5 during the RI. Results for this sample were below the site-specific RAOs for sediment. Therefore, none of the sediment from TFM Pond 5 required Remedial Design Data Evaluation Report Sediment Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_05_Final.doc 5-5 03/04/2013 incorporation into the consolidation cell. 5.2.6 TFM Mid-Site Ravine Results Sediment samples were collected from five locations in along the Mid-Site Ravine that traverses the TFM Site near the former smelter operations during RD field activities. Three samples were collected from each location (0 to 0.5 ft bgs, 0.5 to 1.0 ft bgs, 1.0 to 2.0 ft bgs). Samples collected from the 0 to 0.5 feet bgs interval were analyzed for TCLP arsenic, cadmium, and lead. Samples collected from the 0.5 to 1.0 ft bgs and 1.0 to 2.0 ft bgs intervals were analyzed for total arsenic, cadmium, and lead to determine the vertical extent of contamination. The results from the RI indicated that metals results in excess of the site-specific sediment RAOs for arsenic and lead were encountered in the 0 to 0.5 ft bgs interval in the Mid-Site Ravine. During the RD, each of the sampling locations (MSR-04 through MSR-08) had results or an analytical reporting limit that exceeded the residential/nonresidential RAO for lead in the 0.5 to 1.0 ft bgs interval. Exceedances of the lead RAO were noted in samples collected from the 1 to 2 ft bgs interval at three locations (MSR-04, MSR-07, and MSR-08). The TCLP result for cadmium in four of five sample locations (MSR-04, MSR- 05, MSR-07, and MSR-08) exceeded the TCLP criteria at the 0 to 0.5 ft bgs interval. The Mid-Site Ravine cuts through the former operations area for the smelter, and waste materials were observed in the Mid-Site Ravine. The Mid-Site Ravine is approximately 1600 ft long and is up to 10 ft wide in places. Samples with metal results in excess of RAOs for sediment were encountered to 1 ft bgs throughout the Mid-Site Ravine, and approximately half of the sample locations exhibited metals results in excess of RAOs to 2 ft bgs. Assuming the depth of contamination of approximately 1 ft bgs across the Mid-Site Ravine and an area approximately 50 percent of the ravine contaminated to 2 ft bgs, approximately 900 cy of sediment above RAOs is estimated in the Mid-Site Ravine for inclusion in the consolidation cell. Assuming that all of the Mid-Site Ravine sediment to 0.5 ft bgs will exceed TCLP criteria, then approximately 350 cy of this contaminated sediment is above the TCLP criteria. 5.2.7 Strip Mine Pit Results Sediment samples were collected from the Strip Mine Pit along transect lines at nine sample locations (transect lines and sample locations are illustrated on Figure 5-1). Sample locations and depths were determined based on visual inspection of sediment cores collected along the transect lines (Table 5-2). Samples were collected from up to three depths for analysis of total arsenic, cadmium, and lead to determine vertical extent of contamination. One sample was also collected at each location for analysis of Remedial Design Data Evaluation Report Sediment Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_05_Final.doc 5-6 03/04/2013 TCLP arsenic, cadmium, and lead. Sample depths varied based upon depth to native material beneath sediment. Native clay and/or weathered shale were typically encountered at 0.5 ft bgs on near the banks of the Strip Mine Pit, and a silty clay was encountered to 2.0 to 3.0 ft bgs in the middle of the Strip Mine Pit. During the RI, sediment samples were collected from 0 to 0.5 ft bgs from six locations near the center line of the Strip Mine Pit. None of the results for these sediment samples exceeded the site-specific RAOs or the TCLP criteria. However, visual observations of waste material slumping into the Strip Mine Pit were made. During the RD, visual observations were made of sediment cores taken along 12 transects at various distances from the banks of the Strip Mine Pit. Table 5-2 presents a description of the visual observations and locations. Waste was observed to a depth of 0.5 ft bgs approximately 5 to 10 ft from the north bank of the Strip Mine Pit at transects SMPT-01 through SMPT-06. Waste was observed to a depth of 0.5 ft bgs approximately 5 to 10 feet from the south bank of the Strip Mine Pit at transect SMPT-09. Waste was observed to 0.5 ft bgs approximately 5 to 10 feet from the west bank at SMPT-10, as well as, approximately 5 to 10 feet from the east and west banks of SMPT-11 and SMPT-12. No waste was observed in the middle of the Strip Mine Pit at any transects. Figure 5-2 depicts the estimated depth of waste material at the Strip Mine Pit. Based on the visual observations, samples were collected from nine of the 12 transects. Sediment samples with lead concentrations at or above the RAO were encountered in the 0 to 0.5 ft bgs interval at all but SMPT-10. Lead exceeded RAOs at depths up to 2 ft bgs at transects SMPT-03, SMPT-05, and SMPT-08. No exceedances of RAOs were noted for arsenic or cadmium. In the 0 to 0.5 ft bgs interval, the TCLP result for cadmium at sample location SMPT-10-05 and the TCLP result for lead at SMPT-05- 05 exceeded the TCLP criteria. No other exceedances of TCLP criteria were noted. The Strip Mine Pit borders the southern edge of the TFM site. Based upon visual observations, fine grained waste was observed predominantly on the north bank of the Strip Mine Pit and also on the east and west banks of the northern section. Waste was only observed in the 0 to 0.5 ft bgs interval. Assuming the depth of fine grained waste is 0.5 ft bgs across areas highlighted on Figure 5-2, approximately 360 cy of sediment/fine grained waste is estimated for inclusion in the consolidation cell. Samples with metal results in excess of RAOs for sediment were encountered in the 0 to 0.5 ft bgs interval and also in the 0.5 to 1.0 ft bgs interval across the Strip Mine Pit. All areas of RAO exceedances for sediment in the 0 to 0.5 ft bgs interval will be removed with the fine grained waste, and the volume of sediment to be incorporated in the consolidation cell are included the 360 cy estimate. RAO exceedances Remedial Design Data Evaluation Report Sediment Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_05_Final.doc 5-7 03/04/2013 were present at two locations in the 0.5 to 1.0 ft bgs interval, and it is estimated that approximately 50 cy of sediment will be removed from that interval and incorporated into the consolidation cell. Two sample locations exhibited exceedances of the TCLP criteria at a depth of 0 to 0.5 ft bgs. Assuming that less than 20 percent of the Strip Mine Pit sediment exceeds TCLP criteria, approximately 70 cy of contaminated sediment is above the TCLP criteria. * * * * * Remedial Design Data Evaluation Report Surface Water Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_06_Final.doc 6-1 03/04/2013 6.0 SURFACE WATER 6.1 RD SURFACE WATER SAMPLING AND DATA COLLECTION Surface water samples collected during the RD were collected for the purpose of characterizing the water for management and/or discharge. It is anticipated that these water bodies may be drained and the water discharged prior to remedial action. Surface water samples were collected from TFM Pond 1, TFM Pond 2, TFM Pond 3, TFM Pond 4, the Mid-Site Ravine, and the Strip Mine Pit. Surface water samples were submitted for analysis of National Pollutant Discharge Elimination System (NPDES) parameters, which potentially include: arsenic, cadmium, lead, manganese, and zinc; total hardness; alkalinity; chloride; sulfate; total suspended solids (TSS); nitrate/nitrite as nitrogen; ammonia as nitrogen; chemical oxygen demand (COD); total organic carbon (TOC); biochemical oxygen demand (BOD-5); and, oil and grease. Field measurements of pH, specific conductivity, turbidity, temperature, and dissolved oxygen were collected during sampling. Table 6-1 provides a summary of the surface water samples, and analytical results are presented in Tables 6-2 through 6-4. Complete laboratory analytical data packages are presented in Appendix D. Surface water results were compared to the following criteria: Residential/non-residential RAO for cadmium, Oklahoma Pollutant Discharge Elimination System (OPDES) General Permit OKR05 for Storm Water Discharges for Industrial Facilities under the Multi-Sector Industrial General Permit within the State of Oklahoma, Sector L Landfills, Land Applications Sites, and Open Dumps, OPDES Permit Requirements for the Hudson Refining Superfund Site in Cushing, Oklahoma, which may indicate likely effluent limitations for the TFM Site. For purposes of data screening the lowest OPDES daily maximum limit was selected, as discharge for purposes of the RA is anticipated to be a one-time, not on-going occurrence. 6.1.1 TFM Pond 1 Surface Water Results One surface water sample and one field duplicate were collected from TFM Pond 1 in March 2012. The surface water sample was collected in the general area of the sediment sample PD1-06, as shown in Figure 5-1. The results for the surface water sample collected from TFM Pond 1 are presented on Table Remedial Design Data Evaluation Report Surface Water Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_06_Final.doc 6-2 03/04/2013 6-2. The zinc result in the surface water sample collected from TFM Pond 1, as well as the field duplicate (11,900 μg/L and 12,000 μg/L, respectively), exceeded the daily maximum for the OPDES General Permit OKR05 (200 μg/L). No other exceedances of screening criteria were present in the surface water sample collected from TFM Pond 1. 6.1.2 TFM Pond 2 Surface Water Results. One surface water sample was collected from TFM Pond 2 in March 2012. The surface water sample was collected in the general area of the sediment sample PD2-05, as shown in Figure 5-1. The results for the surface water sample collected from TFM Pond 2 are presented on Table 6-2. The zinc result in the surface water sample collected from TFM Pond 2 (1,490 μg/L) exceeded the daily maximum for the OPDES General Permit OKR05 (200 μg/L). No other exceedances of screening criteria were present in the surface water sample collected from TFM Pond 2. 6.1.3 TFM Pond 3 Surface Water Results One surface water sample was collected from TFM Pond 3 in March 2012. The surface water sample was collected in the general area of the sediment sample PD3-06, as shown in Figure 5-1. The results for the surface water sample collected from TFM Pond 3 are presented on Table 6-2. The zinc result in the surface water sample collected from TFM Pond 3 (2,200 μg/L) exceeded the daily maximum for the OPDES General Permit OKR05 (200 μg/L). No other exceedances of screening criteria were present in the surface water sample collected from TFM Pond 3. 6.1.4 TFM Pond 4 Surface Water Results One surface water sample was collected from TFM Pond 4 in March 2012. The surface water sample was collected in the general area of the sediment sample PD4-02, as shown in Figure 5-1. The results for the surface water sample collected from TFM Pond 4 are presented on Table 6-2. The zinc result in the surface water sample collected from TFM Pond 4 (933μg/L) exceeded the daily maximum for the OPDES General Permit OKR05 (200 μg/L). No other exceedances of screening criteria were present in the surface water sample collected from TFM Pond 4. 6.1.5 Mid-Site Ravine Surface Water Results Surface water samples were collected from four locations (MSR-05 through MSR-08) within the Mid-Site Ravine in March 2012. The surface water samples were collected in the general area of the sediment samples MSR-05 through MSR-08, as shown in Figure 5-1. The results for the surface water sample Remedial Design Data Evaluation Report Surface Water Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_06_Final.doc 6-3 03/04/2013 collected from Mid-Site Ravine are presented on Table 6-3. The zinc results in all four surface water samples collected from the Mid-Site Ravine (ranged from 1,630 to 11,600 μg/L) exceeded the daily maximum for the OPDES General Permit OKR05 (200 μg/L). The Oil and Grease result for the surface water sample collected at MSR-05 (35.7 milligrams per liter [mg/L]) exceeded the daily maximum for the Oil and Grease criteria based on the Hudson Refining Superfund Site OPDES Permit (15.0 mg/L). This result should be verified prior to the RA as all other Oil and Grease results were non-detect. The cadmium result for the surface water sample collected at MSR-08 (286 μg/L) exceeded the surface water RAO for cadmium (238 μg/L). It should be noted that the highest concentrations of metals were at location MSR-08, which also exhibited the highest TSS and turbidity. No other exceedances of screening criteria were present in the surface water samples collected from the Mid-Site Ravine. 6.1.6 Strip Mine Pit Surface Water Results Surface water samples were collected from three locations (SMPT-06, SMPT-08, and SMPT-11) within the Strip Mine Pit in March 2012. The surface water samples were collected in the general area of the sediment samples transects SMPT-06, SMPT-08, and SMPT-11, as shown in Figure 5-1. The results for the surface water sample collected from Strip Mine Pit are presented on Table 6-4. The sulfate results in all three surface water samples collected from the Strip Mine Pit (ranged from 631 to 643 mg/L) exceeded the daily maximum for the sulfate criteria (550 mg/L), which is based on the Hudson Refining Superfund Site OPDES Permit. No other exceedances of screening criteria were present in the surface water sample collected from the Strip Mine Pit. * * * * * Remedial Design Data Evaluation Report Ground Water Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_07_Final.doc 7-1 03/04/2013 7.0 GROUND WATER 7.1 HYDROGEOLOGY No major bedrock or alluvial aquifers lie beneath the TFM Site. The Seminole Formation, the upper bedrock beneath the TFM Site, consists of shale, sandstone, and thin coal beds and has a thickness of approximately 200 ft. The Seminole Formation reportedly yields small amounts of fair to poor quality water and has been designated Class IIB as a minor use general basin (OAC, 2004). There are no municipal or other public water wells or Wellhead Protection Areas within a 4-mile radius of the TFM Site. Based on RI and RD activities, the occurrence of ground water beneath the TFM Site is very limited; however, it does appear to be continuous across the TFM Site. A hydrogeological investigation was conducted during the RD to meet the requirements of OAC 252:515. The hydrogeologic investigation was designed to meet permit requirements for the consolidation cell. Based on the assumption of an approximate ten acre consolidation cell, six borings were installed to 30 ft below the lowest elevation of the bottom of the waste materials in the consolidation area and these locations are shown on Figure 7-1. One boring (B-05) was advanced to approximately 100 ft bgs. Borings were advanced to bedrock (approximately ten ft bgs) using “dry methods” and were advanced to total depth using coring methods. Lithologic logs were prepared for each boring, and are presented in Appendix E. One geotechnical soil sample was collected from each type of soil encountered. Previous investigations indicated there were up to four types of unconsolidated materials present at the TFM Site: a silty loam/silty sand; a clay; a lower silty loam/silty sand; and the waste material. The geotechnical soil samples were submitted for analysis of Atterberg limits, hydraulic conductivity, sieve with hydrometer, and specific water/moisture content. Geophysical logging using gamma ray/neutron logs was performed at three of the borings (B-03, B-04, and B-05). The geophysical data and geotechnical data are presented in Appendix E and will be evaluated during the remedial design. 7.2 MONITORING WELL INSTALLATION Four monitoring wells (MW-07, MW-08, MW-09, and MW-10) were installed to monitor ground water elevation in the proposed consolidation cell area (Figure 7-1). Based upon previous investigations, ground water is present in an unconfined condition in a thin zone located directly above bedrock. A lithologic log was prepared for each boring and is presented in Appendix E. Borings were continuously sampled to the top of bedrock using a HSA drilling techniques. The monitoring wells were constructed with five ft of screen that straddles the top of ground water. Following installation, each monitoring well was developed in accordance with SOP TFM-107 which is provided in the RD FSP. Additionally, each Remedial Design Data Evaluation Report Ground Water Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_07_Final.doc 7-2 03/04/2013 monitoring well was surveyed in order to obtain horizontal coordinates and top of casing elevation data. Monitoring well construction details are presented in Table 7-1. Monitoring well survey data, well development forms, field sampling forms, construction diagrams, and drilling logs are located in Appendix E. 7.3 WATER LEVEL MEASURMENT COLLECTION Ground water elevation measurements are being collected monthly in accordance with OAC 252:515 Subchapter 7, Part 5, Ground Water Study. Table 7-2 presents monthly ground water elevations collected to date at the TFM Site. Water level gauges were installed in all four ponds and the Strip Mine Pit, and surface water elevation measurements (Table 7-3) are recorded monthly at the same time of ground water elevation measurements. Although ground water elevation measurements are only required for the four piezometers in close proximity to the proposed consolidation cell, ground water elevation measurements are collected from all of the TFM Site monitoring wells, including seven existing monitoring wells and four new monitoring wells. On March 29, 2012 a datalogger was installed in monitoring well MW-02 to provide continuous hourly ground water elevation data. Ground water data from the data logger will be downloaded at the same time as the monthly ground water elevations are collected. Figures 7-2 to 7-4 present the potentiometric surface maps that were constructed based upon ground water level measurements during each quarterly sampling event. Ground water flow direction was toward the southeast for each sampling event. Monthly potentiometric surface maps, ground water levels (including from the data logger) will be presented in detail under a separate Ground Water Report. 7.4 MONITORING WELL SAMPLING AND DATA COLLECTION RI data indicates that waste materials are present at depths that could intercept shallow ground water. Three ground water sampling events conducted during the RI indicated that contamination is not present in ground water and migrating off-site; this determination was made using six on-site wells and one downgradient off-site well. Although not required during the design phase, quarterly ground water sampling of seven existing and four newly installed monitoring wells is being conducted to add to the RI data that support the determination that contamination is not present in ground water and migrating off-site. The first three quarterly ground water sampling events were conducted on April 16-17, 2012, July 10-11, 2012, and October 15-16, 2012. Monitoring Wells MW-01 to MW-10 were sampled using low-flow sample collection techniques with a peristaltic pump and Teflon-line polyethylene tubing. Samples were collected from each well and submitted to SEL for analysis of arsenic, cadmium, and lead, as both field- Remedial Design Data Evaluation Report Ground Water Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_07_Final.doc 7-3 03/04/2013 filtered and unfiltered samples, as volume allowed. During the July 2012 sampling event, only total metals were collected from Monitoring Well MW-08, due to limited sample volume. Tables 7-4 through 7-14 presents the analytical ground water results from the first two quarterly ground water sampling events (third quarter analytical data was not available at the time of this report) during the RD, as well as analytical groundwater data from the three sampling events conducted during the RI at Monitoring Wells MW-1 to MW-06. Complete laboratory analytical data packages are presented in Appendix D. The analytical results of the ground water sampling events will be discussed in detail under a separate Ground Water Report. * * * * * Remedial Design Data Evaluation Report Ecological Evaluation Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_08_Final.doc 8-1 03/04/2013 8.0 ECOLOGICAL EVALUATION 8.1 ECOLOGICAL SITE RECONNAISSANCE An ecological site reconnaissance was completed on March 15, 2012 by a BMcD biologist familiar with the regional flora and fauna. The TFM Site is located within the Osage Cuestas (Level IV) ecoregion of Oklahoma (Woods, 2005). The Osage Cuestas ecoregion is an irregular to undulating plain that historically consisted mostly of tall grass prairie with some oak–hickory and riparian forests. The native vegetation communities were converted to managed rangeland and cropland as the area was settled and developed. The TFM Site is vegetated by various grass species, trees, and shrubs creating diverse habitat types. There are areas of dense woody vegetation interspersed with sparsely vegetated grassy areas and patches of bare or rocky ground. The open grassy areas at the TFM Site included Bermuda grass (Cynodon dactylon), little bluestem (Schizachyrium scoparium), Johnson grass (Sorghum halepense), tall dropseed (Sporobolus asper), bristle grass (Seteria spp.), Canada goldenrod (Solidago canadensis), Oklahoma blackberry (Rubus oklahomus), and scattered green hawthorn (Crataegus virdis), eastern red cedar (Juniperus virginiana), and smooth sumac (Rhus glabra) shrubs. Wooded areas included blackjack oak (Quercus marilandica), eastern red cedar, hackberry (Celtus occidentalis), elm (Ulmus spp.), dogwood (Cornus spp.), Japanese honeysuckle (Lonicera japonica), and saw greenbrier (Smilax bona-nox). Species present in the wetter areas along the edges of the ponds included boxelder (Acer negundo), American sycamore (Platanus occidentalis), eastern cottonwood (Populus deltoides), black willow (Salix nigra), button bush (Cephalanthus occidentalis), smartweed (Polygonum spp.), and common cattail (Typha latifolia). Minimal wildlife was observed during the November 27, 2006, RI field survey; however, several common wildlife species were observed during the March 15, 2012, field survey. These species included northern cricket frog (Acris crepitans), plains leopard frog (Rana blairi), ground skink (Scincella lateralis), five-lined skink (Eumeces faciatus), common garter snake (Thamnophis sirtalis), Northern Cardinal (Cardinalis cardinalis), Northern Mockingbird (Mimus polyglottos), American Robin (Turdus migratorius), Downey Woodpecker (Picoides pubescens), Red-winged Blackbird (Agelaius phoeniceus), Killdeer (Charadrius vociferous), and European Starling (Sturnus vulgaris). At the north end of the TFM Site, Wild Turkey (Meleagris gallopavo) feathers were observed in wooded and grassy areas and several skinks had been impaled on spines in hawthorn trees by a Loggerhead Shrike (Lanius ludovicianus). Additional wildlife species that likely occur on the TFM Site but not observed during the field surveys Remedial Design Data Evaluation Report Ecological Evaluation Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_08_Final.doc 8-2 03/04/2013 include Woodhouse’s toad (Bufo woodhousei), box turtle (Terrapene spp.), black ratsnake (Elaphe obsoleta), racer (Coluber constrictor), fox squirrel (Sciurus niger), raccoon (Procyon lotor), opossum (Didelphis virginiana), striped skunk (Mephitis mephitis), red fox (Vulpes fulva), coyote (Canis latrans), white-footed mouse (Peromyscus leucopus), eastern cottontail (Sylvilagus floridanus), white-tailed deer (Odocoileus virginianus), mourning dove (Zenaida macroura), cooper’s hawk (Accipiter cooperii), barn swallow (Hirundo rustica), and scissor-tailed flycatcher (Tryannus forficatus). These are common species that are typically found in areas that exhibit varying amounts of disturbance. Hunting decoys were present in the on-site ponds during the 2006 field survey; however, no waterfowl were observed during the 2006 and 2012 field surveys. It was assumed that waterfowl would be present on the ponds at the TFM Site at least some time during the year. During a site visit conducted during USEPA’s Removal Assessment, local fishermen reported that catfish and bass were present in the southern strip mine pit (USEPA, 1999). According to the U.S. Fish and Wildlife Service (USFWS) and Oklahoma Natural Heritage Inventory (ONHI) database (ONHI, 2003), the following protected species are known or are likely to occur in Tulsa County: Common Name Scientific Name Federal Status State Status American Burying Beetle Nicrophorus americanus Endangered Endangered Bald Eagle Haliaeetus leucocephalus Delisted Endangered Least Tern Sterna antillarum Endangered Endangered Piping Plover Charadrius melodus Threatened Threatened Texas Horned Lizard Phrynosoma cornutum -- Candidate However, none of the protected species known or likely to occur in Tulsa County were observed at the TFM Site and none are likely to occur because of the disturbed nature of the TFM Site and amount of development in the vicinity of the TFM Site. No bald eagles, which prefer to nest and roost in large trees and snags along large rivers and reservoirs, were observed during the site visit. Similarly, no raptor stick nests were present in any of the trees at or in the immediate vicinity fo the TFM Site. According to the USFWS, Tulsa County is situated along the probable migratory pathway for the Least Tern and Piping Plovers between breeding and wintering habitats. Tulsa County also contains sites (e.g., Remedial Design Data Evaluation Report Ecological Evaluation Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_08_Final.doc 8-3 03/04/2013 isolated sandbars along the Arkansas River) that could provide stopover habitat during the migration. Potential nesting and loafing habitat for Least Terns and Piping Plovers, which includes sandbars in large rivers like the Arkansas River, is not present at the TFM Site. Although Texas horned lizards occur in open areas with clumping grasses for cover, they are unlikely to occur at the TFM Site because of the amount of disturbance and broken retorts and condensers, slag, building debris, ash, and bricks present in the open areas. 8.2 AMERICAN BURYING BEETLE SURVEY Prior to the start of the RD, a survey was conducted at the TFM Site for the American Burying Beetle (ABB), September 12-19, 2011, by Eagle Environmental Consulting, Inc. of Vinita, Oklahoma. No ABBs were present on the TFM Site. The survey was valid until May 20, 2012. A copy of the ABB survey is provided in Appendix F. An ABB survey was also completed in support of the RI and no ABBs were present on the TFM Site at that time. * * * * * Remedial Design Data Evaluation Report Air Monitoring Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_09_Final.doc 9-1 03/04/2013 9.0 AIR MONITORING 9.1 PERIMETER AIR MONITORING Results of perimeter air monitoring conducted during the RI indicated that the TFM Site was not a source of airborne contamination to off-site locations (BMcD, 2007). No additional perimeter air sampling was deemed necessary for the RD. 9.2 PERSONAL AIR MONITORING Exposure monitoring of site personnel was conducted during activities that disturbed soil and/or waste material (i.e. trench sampling or soil borings). Real-time dust monitoring was also conducted to measure total dust during active soil and/or waste disturbance activities. Real-time dust readings were recorded during the excavation of test pits and trenching activities which occurred on March 6-7, 2012. Real-time dust results were below the 0.3 milligrams per cubic meter (mg/m3) action limit in the RD HSP; therefore, no upgrade in personal protective equipment (PPE) was required. Results of real-time dust levels are presented in Appendix G. In addition, personal air monitoring was conducted during the initiation of field activities that disturb soil and/or waste materials. The initial monitoring was used to judge expected ranges of exposure for workers and to select appropriate levels of PPE. Personal air monitoring was completed on March 6-7, 2012. Personal sampling pumps with an inline cassette were attached to the equipment operator digging the test pits/trenches, BMcD field personnel collecting samples from the test pits/trenches, and BMcD field personnel performing soil logging of the monitoring well/boring installations. The personal sampling pumps were worn for the duration of the work shift. Samples were submitted for analysis of arsenic, cadmium, and lead. All samples were non-detect for arsenic and cadmium, and two samples had low-level detections of lead. The lead detections of 1.1 micrograms per cubic meter (μg/m3) and 1.4 μg/m3 were below the permissible exposure limit (PEL) of 50 μg/m3. Results of the personal air monitoring are presented in Appendix G. * * * * * Remedial Design Data Evaluation Report Waste Consolidation Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_10_Final.doc 10-1 03/04/2013 10.0 WASTE CONSOLIDATION 10.1 INVESTIGATION DERIVED WASTE IDW generated during the RD was disposed of on-site in accordance with the Guide to Management of Investigation-Derived Wastes (USEPA, 1992). All solid IDW generated from soil borings, soil sampling, and monitoring well installation was spread on the ground surface around the location from which it was generated. All liquid IDW generated from monitoring well development and purging, surface water sampling, and monitoring well sampling was discharged near the location from which it was generated. Eleven (11) drums of IDW generated during the RI were still on-site at the start of the RD field activities. Due to the poor condition of the IDW drums, the ODEQ project team was consulted, and it was decided that they would be incorporated into the waste area. The 11 drums were moved to the area near TR-25. The solid IDW was removed from the drums and incorporated into a trench in the waste area. The empty drums were then compacted and incorporated into the trench. Handling the IDW in this manner is appropriate since it does not pose unacceptable risk to human health and the environment in the interim and any potential risks that are posed in the long term by the wastes will be addressed by the remedy as defined in the record of decision (ROD). 10.2 WASTE TIRES Individual and piles of waste tires were present on the TFM Site, specifically in the area south of the former residence. During the RD field activities, the waste tires were consolidated to the TFM Site gate, and removed by the ODEQ Land Protection Division for recycling. * * * * * Remedial Design Data Evaluation Report References Tulsa Fuel and Manufacturing - Collinsville, Oklahoma RD_Data_Rpt_11_Final.doc 11-1 03/04/2013 11.0 REFERENCES Burns & McDonnell Engineering Company, Inc.
