INTRODUCTION The purpose of a Five-Year Review (FYR) is to evaluate the implementation and performance of a remedy to determine if the remedy is and will continue to be protective of human health and the environment. The methods, findings, and conclusions of reviews are documented in five-year review reports such as this one. In addition, FYR reports identify issues found during the review, if any, and document recommendations to address them. The United States Environmental Protection Agency is preparing this FYR pursuant to the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) Section 121, consistent with the National Contingency Plan (NCP) (40 Code of Federal Regulations (CFR) Section 300.430(f)(4)(ii)), and considering EPA policy. This is the sixth FYR for the A. L. Taylor Superfund site (the Site). The triggering action for this statutory review is the completion date of the previous FYR. The FYR has been prepared because hazardous substances, pollutants, or contaminants remain at the Site above levels that allow for unlimited use and unrestricted exposure (UU/UE). The Site consists of one Operable Unit (OU), OU1, which is addressed in this FYR. EPA remedial project manager (RPM) Yvonne Jones led the FYR. Participants included EPA community involvement coordinator (CIC) Angela Miller, EPA site attorney Stedman Southall, EPA Hydrologist Noman Ahsanuzzaman, EPA toxicologist Kevin Koporec, EPA ecological risk assessor Brett Thomas, EPA IC Legal Coordinator Bilal Harris and the Kentucky Department for Environmental Protection (KDEP) Project Manager Shital Jiwane. KDEP conducted the FYR and prepared this report regarding the remedy implemented at the Site. The review began on November 13, 2017. A list of documents reviewed as part of this FYR is included in Appendix A. A summary of the current site status is included in Appendix B. Site Background The A.L. Taylor site is a 23-acre site located on Letts Road, directly off Highway 1020, in Brooks, Bullitt County, Kentucky just south of the Jefferson County line (Figure E-1). The Site has 17 acres of wooded, grassy areas and a 6-acre capped landfill enclosed by a security fence. Woods border the Site to the north and west. Several private rural residences and a golf course are located to the south and east of the Site. Wilson Creek is a small stream which runs along the eastern edge of the Site and flows northward into Pond Creek. Pond Creek eventually drains into the Salt River just before the Salt River's confluence with the Ohio River (Figure E-2). The owner operated an unpermitted waste disposal and drum storage facility at the Site from 1967 until 1977. The exposed drums and hazardous materials buried at the Site leached contaminants into soil and groundwater. Surface water runoff carried the contamination towards Wilson Creek. The Kentucky Natural Resources and Environmental Protection Cabinet (KNREPC) became involved in 1975, when several complaints were received regarding multicolored chemical spills and an oily sheen in Wilson Creek. In 1979, the EPA responded to a surface water pollution emergency and began initial cleanup of the Site. During the emergency response actions, the EPA constructed a temporary runoff collection and treatment system and removed the drums from the Site. However, contaminated soils were left on site which needed remedial action. The EPA conducted a remedial investigation/feasibility study (RI/FS) and placed the Site on National Priorities List (NPL). The remedial measures for the Site included 1 installation of a clay cap, a perimeter drainage system, groundwater monitoring wells and a security fence. The Site was deleted from the NPL in 1996. The Site is currently not in use but KDEP performs routine operation and maintenance (O&M). Additional background information about the Site such as a site chronology is provided in Appendix C (Table C-1) whereas Appendix D includes site history, physical characteristics and land use at the Site. Appendix E includes site maps and figures. FIVE-YEAR REVIEW SUMMARY FORM SITE IDENTIFICATION Site Name: A. L. Taylor (Valley of the Drums) EPAID: KYD980500961 Region: 4 State: KY City/County: Brooks, Bullitt County NPL Status: Deleted Multiple OUs? No Has the site achieved construction completion? Yes SITE STATES REVIEW STATUS Lead agency: EPA Author name: Yvonne Jones (EPA) and Shital Jiwane, P.E. (KDEP) Author affiliation: EPA and KDEP Review period: 11/13/2017 - 9/26/2018 Date of site inspection: 11/29/2017 Type of review: Statutory Review number: 6 Triggering action date: 9/26/2013 Due date (fiveyears after triggering action date)'. 9/26/2018 II. RESPONSE ACTION SUMMARY Basis for Taking Action KNREPC discovered the Site as early as 1967 when fire burning for a week at the Site was reported. The State identified the Site as a waste disposal site and informed the owner, Mr. Taylor that he could operate an approved sanitary landfill at the Site with proper permits. Mr. Taylor never applied for any permits and continued receiving and disposing waste illegally at the Site. The paint and coating 2 industries of the Louisville area were the primary waste generators using the Site. Solvent waste from drums was dumped into excavated pits and burned off. The wastes were buried in trenches and thousands of drums were stored on the ground surface during later years of operation. These activities had greatly disturbed the surface features of the Site and resulted in substantial pollution of groundwater, surface water, soils and sediment. The Site caught attention of the KNREPC again in 1975. This was the first time state officials documented releases of hazardous substances from the Site into nearby Wilson Creek. From 1979 till 1981, the EPA and KNREPC conducted emergency removal actions to prevent further releases of oil and hazardous substances. However, a site inspection in 1981 revealed that deteriorating and leaking drums were still discharging contaminants into Wilson Creek. In 1982, erosion at the Site partially exposed a buried drum which indicated that contamination still existed in surface soils. Between 1979 and 1984, numerous investigations were carried out and analytical data was collected to determine the extent of contamination. Over the course of these investigations, 140 contaminants were identified. The 1984 Feasibility Study Addendum and Endangerment Assessment identified the contaminants found most often and in highest concentrations. These contaminants included: xylene, phthalates, toluene, alkyl benzenes, methyl ethyl ketone, methylene chloride, acetone, anthracene, vinyl chloride, trans-1,2 dichloroethylene, fluoranthene and aliphatic acids. Polychlorinated Biphenyls (PCBs) were found in low concentrations in surface soils and sediments in Wilson Creek. Several metals, including barium, lead, zinc, copper, strontium, magnesium and chromium were detected in soils, surface water and groundwater in concentrations exceeding natural background levels for groundwater but were below National Drinking Water Standards. The 1984 Feasibility Study Addendum and Endangerment Assessment also discussed human health risk scenarios and evaluated groundwater and surface water as potential routes of exposure to hazardous substances released from the Site. However, neither type of water source appeared to be a likely route of exposure to populations located downstream of surface water routes or downgradient of groundwater movement from the Site. There was little potential for exposure to contaminants in groundwater because most nearby properties were connected to the public water supply. Additionally, the aquifer produced low yields of poor water quality. Surface water, like groundwater was not considered a potential exposure route because it was not a source of drinking water for populations downstream of Wilson Creek. Recreational use of the streams leading from the Site was not documented. However, it was believed to be low or infrequent above the Ohio-Salt river confluence. Another factor limiting future human exposure risks was the limited population growth projected in the vicinity of the Site. Topographic features of the area surrounding the Site made it largely imsuitable for development. The principal environmental impact from the Site was considered to be the discharge of contaminated surface water runoff to Wilson Creek and subsequently downstream. However, the greatest risk of adverse health effects was present for persons entering the Site because of the ease of access to the Site and the high levels of organic chemicals and metals remaining in surface soil, runoff water and in burial pits. Therefore, an effective remedial plan was warranted to mitigate potential adverse impacts on human health, welfare and environment. Response Actions At the request of KNREPC, the EPA began the first emergency response action for the Site in 1979. Under the authority of Section 311 of the Clean Water Act, EPA prevented further releases of pollutants into nearby Wilson Creek by constructing interceptor trenches and a temporary water treatment system, securing leaking drums and segregating and organizing drums on site. Approximately 17,000 drums Status of Implementation Remedial design for the Site began in May 1986 and focused on designing components for the onsite containment remedy. The active contaminant migration pathway at the Site was determined to be by surface water runoff coming into contact with contaminated soils. A landfill cap was proposed as a method of containing waste materials and preventing contact between surface water and waste. Remedial action activities began at the Site on April 20, 1987. Remedial measures included installation of a clay cap, a perimeter drainage system, groundwater monitoring wells and security fence. Activities prior to the installation of the cap included clearing the vegetation and structures from the Site and draining the contents of a runoff control pond built by EPA in 1981 during the initial emergency response actions. Pond sediments were stabilized and the pond was refilled with water. Areas with suspected buried waste which were outside of the intended cap were excavated and any waste found was reburied in the cap area. Site borrow material was used in all depressions and low spots to prepare the Site for capping. The cap consisted of an impervious layer with a minimum of 36 inches of clay, an 18- inch pervious drainage layer (gravel), and a 12- inch topsoil layer with grass vegetative cover. Perimeter surface diversion ditches were constructed around the cap primarily to reduce erosion of the cap by runoff. The ditches were lined with riprap, seeded with a mixture of grasses and mulched with straw. Two culverts were installed at the northern and southern ends of the Site under the main access road. Construction of the cap and drainage ditches was completed in July 1987. A six-foot high chain link security fence with appropriate gates was installed outside the cap area in an effort to limit unauthorized entry onto the Site. The security fence encloses approximately six acres of the Site. The remaining 17 acres is a wooded and grassy area. Twelve groundwater monitoring wells were placed around the landfill to detect movement if any, of contaminants migrating off site towards Wilson Creek. Reseeding and regrading was performed around the cap in the fall of 1988 due to erosion problems. Larger drainage ditches and culverts were constructed to withstand a 25-year/24-hour rainfall. Remedial construction was officially completed in March 1989 and a close out report was published on August 10, 1990. The EPA performed O&M activities from September 1988 through February 1990. In July 1989, the EPA and KNREPC (now KDEP) signed the Superfuiid State Contract for O&M activities. The contract stated that KNREPC would perform the Site's O&M activities and identified the specific responsibilities of both agencies. The EPA and site PRPs signed a Consent Decree (CD) in October 1991. In the CD, the PRPs agreed to repay costs incurred by the EPA during the initial response actions to clean up the Site. The PRPs also agreed to provide funding to perform monitoring and O&M activities at the Site. The Superfimd State Contract required that EPA provide KNREPC with this funding from the PRPs to conduct O&M activities and repair on-site utility poles as needed. However, the contract required that KNREPC provide all necessary personnel, equipment and services to carry out required O&M activities. In May 1996, the EPA deleted the Site from the NPL. This deletion does not preclude future action under Superfimd. As a matter of EPA’s policy, a review of the Site has been conducted at least every five years after the initiation of the remedial action at the Site to ensure that the remedy remains protective of human health and the environment. The First FYR report was published in 1992 and subsequent FYRs have been published since. During a site inspection in 2007, the EPA found drum carcasses and hardened paint sludges resembling rocks at various locations near Wilson Creek. The investigations of the paint sludges began in 2010 continuing into 2011 which included identilying the areas containing paint waste, soil and sediment sampling and waste characterization. The paint waste was found to be non-hazardous and was cleaned up in March 2017. Institutional Controls The ROD did not call for ICs. There are no restrictions in place to protect the integrity of the remedy and prevent exposure to contaminated groundwater at the Site. According to the ROD, groundwater is not a source of drinking water near the Site because the aquifers produce low yields of poor quality. The residences and businesses near the Site obtain their drinking water from the public water supply. Options for ICs restricting groundwater and land use at the Site need to be evaluated to ensure that fiiture use will remain protective of human health and the environment. Table 2 lists the potential ICs associated with the Site. Figure E-3 shows the location of the Site parcel requiring ICs.

The O&M plan provided the procedures to be followed during the closure and 30-year post closure period for maintaining the cap, drainage ditches, security fence, and the site access road and monitoring groundwater and surface water at the Site. The revised Final O&M plan estimated long-term O&M costs for a post-closure period of 30 years to be $998,875. According to the revised Final O&M plan, regularly scheduled observation and maintenance activities at the Site include; ' • Performing field observations each year during January and during April through October. • Observing the topsoil and grass cover regularly identifying potential erosional areas. • Conducting regular observations including topographic surveys for settlement of the cover and the landfill. • Inspecting the cap and surrounding area for leachate seepage. • Ensuring adequate growth of grass cover to prevent erosion. • Performing regular observations for areas with ponded water. • Regularly mowing the cover and areas adjacent to the riprap slopes, monitoring wells, access roads, ash seepage barrier and security fences. • Inspecting and maintaining the perimeter drainage system including control of vegetation in the ditch to ensure proper functioning. • Checking if monitoring wells, security fence, access road are maintained properly. • Sampling and analysis of groundwater from the monitoring wells to check water quality. • Sampling and analysis of surface water upstream and downstream of any areas contributing to Wilson Creek. EPA performed the O&M activities from September 1988 through February 1990. In July 1989, EPA and KNREPC (now KDEP) signed a Superfimd State Contract in which EPA transferred the responsibility of conducting the O&M activities to KDEP for 29 years. Since 1990, KDEP has conducted O&M activities at the Site except for a period from 2003 to 2007 when regular O&M did not occur. Since 2008, O&M activities have taken place on a more regular basis. Since the last FYR in 2013, periodic field observations have been performed regularly to ensure that the cap, fence and monitoring wells are maintained properly and to identify if potential problem areas exist at the Site. The other O&M activities at the Site included mowing, maintaining security fence, weeds and vegetation control on a semi-annual basis. Starting in 2016, mowing and herbicide application activities have been conducted three times a year, in spring, summer and fall. Annual groimdwater sampling activities were conducted regularly each year except in 2014. All twelve groundwater monitoring wells were purged and sampled using low flow sampling methodology. Surface water and sediment samples at Wilson Creek have not been collected regularly. KDEP collected the samples only once in December 2017. In September 2015, during a routine site visit, a depression of approximately 15 feet in diameter and 4 inches in depth was observed on the cap. According to the final O&M Manual Section 3.1.1 this was considered a minor settlement. It was filled in, compacted and reseeded in November 2015. Subsequent inspections have noted vegetation growth and no additional erosion. On multiple site visits it was noted that excessive erosion was occurring outside the fenced area due to off-road all-terrain vehicle and motorcycle activity. The fence in this area was also showing excessive wear and numerous posts were bent or broken. KDEP consulted with EPA and it was decided that the lower section of fence nearest to Wilson Creek should be replaced. Accordingly, in 2015, KDEP extended the fence by 10 feet encompassing the area of trespass within the restricted zone. This has greatly reduced trespassing in this area. During the fence replacement the front gates were also replaced due to vandalism and poor condition. In September 2016, a topographic survey was conducted to evaluate the settling of the cap. No settling of the cap was documented based on the elevations of survey monuments installed during the initial cap installation. These survey monuments are surveyed every five years to determine if any settling of the capped area has occurred. The presence of solidified paint and drum carcasses in surface water and sediments along the Wilson Creek was first noted during the 2008 FYR. Since then, KDEP and EPA did numerous investigations to identify and characterize the waste. During March 2017, hand tools were utilized to remove visible accessible solidified paint (Figure E-4). Four 55-gallon drums worth of paint debris were collected from along the stream banks and from the channel. These drums were transported for disposal in a landfill as a non-hazardous special waste. The southeastern area of the Site (Figure E-5) has been impacted from water flowing off the cap via letdown channels. To address the ponding in this area, as a short-term measure, KDEP contractor 8 Library, located at 127 North Walnut Street, Shepherdsville, Kentucky 40165; and, on the EPA website: https ://www.epa. eov/superfiind/ search-sunerfund-fi ve-year-reviews. Data Review As per the requirements in the ROD, groundwater, surface water and/or sediments have to be sampled and analyzed annually. KDEP collected groundwater samples annually between 2013 and 2017 except in 2014. However, sirface water and sediment samples were collected only once in December 2017. The sampling data was reviewed to determine if pattern or trends of exceedances within certain media exist. The ROD did not mention any COCs or any clean-up levels associated with the COCs such as Applicable or Relevant and Appropriate Requirements (ARARs), therefore To Be Considered (TBCs) criteria was used to compare the results. AFLARs review can be foimd in Appendix H. Data tables (Table I-l, 1-2 and 1-3) from KDEP’s sampling events are presented in Appendix I. Sampling results by the media are summarized below. Groundwater Groundwater samples were collected from existing monitoring wells, ALT-1 through ALT-12 in November 2013, October 2015, October 2016 and December 2017. An additional well ALDW-2 was sampled once in 2013. This well has not been sampled since 2013. The samples were analyzed for metds, VOCs, Semi Volatile Organic Compounds (SVOCs), Pesticides and PCBs except in 2013, they were only analyzed for VOCs and SVOCs. In 2016, pesticides were not analyzed. The results were compared to the most stringent drinking water Maximum Contaminant Levels (MCLs). In the absence of MCLs, comparison was made with tap water Regional Screening Levels (RSLs). The analysis of the groundwater data from the sampling events indicate that SVOCs, PCBs and pesticides were not detected in any of the events. Among metals, barium was detected in most wells but was below the regulatory limit. Chromium was detected in few wells but in trace amounts. The only metal which exceeded the MCL was Lead in well ALT-2 but only once in 2015. For Arsenic, the laboratory used a detection limit of 25 pg/L in 2015 and 2016 sampling events, which is higher than the MCL of 10 pg/L. Therefore, arsenic exceedance could not be determined for those events. In 2017, the laboratory detection limits were modified and Arsenic was detected below the MCL but above the RSL in well ALT-7. As for the VOCs, only two were detected, 1-1 dichloroethane and cis-1,2-dichloroethene in wells ALT-9 and ALT-6 respectively. 1-1 dichloroethane in ALT-9 exceeded the RSL in three of the four sampling events whereas cis-1,2-dichloroethene in well ALT-6 exceeded only once in 2015. Surface Water and Sediments Two surface water samples were collected in Wilson Creek, one downstream and one upstream during the annual sampling event in December 2017. Only metals were detected in surface water but were well below the regulatory limits. KDEP collected two sediment samples at the same location where surface water samples were collected in Wilson Creek. The results were compared to the most recent regional screening levels for residential and industrial soils and Region 4 Ecological Screening Values for Sediments. The contaminants detected were metals. Polycyclic Aromatic Hydrocarbons (PAHs) and PCBs but the concentrations were low. The only exception being Aroclor 1260 which exceeded the residential soil level in the downstream sample. In addition to KDEP’s annual sampling events, as a part of the dried paint waste investigation and characterization activities at Wilson Creek, a private contractor, Linebach Funkhouser Inc., performed soil, sediment and paint sludge sampling in 2010 and 2011. The sampling was performed to assess the impact of waste paint sludge and empty drums on underlying natural soil/sediments. During the investigation, the contractor collected and analyzed: 29 surficial soil and sediment samples (0 to 0.5 feet deep) including 20 sediment samples from Wilson Creek, 53 shallow subsurface soil samples (0.5 to 2 feet deep) and 90 deeper subsurface soil samples (2 to 10 feet deep). The results of the investigation were published in Areas of Concern Characterization Report submitted to KDEP dated August 5, 2011 and summarized below. Soil and Sediments The soil samples were collected immediately below the observed waste material from the southern portion near well ALT-6, northern portion outside the cap and adjacent to the bed of Wilson Creek. Sediment samples were collected directly from the bed of Wilson Creek. The samples were analyzed for RCRA Metals, VOCs, PAHs, and PCBs. Benzo(a) pyrene and arsenic were detected slightly in excess of its risk based screening level for residential soil in some samples in 2010 whereas Aroclor 1254 and/or 1260 were detected above risk based screening levels for non-restricted site use in some samples collected near Wilson Creek in both 2010 and 2011. The sediment sampling results were consistent with the soil sampling results. The sediments in Wilson Creek bed had been affected by the PCBs, Aroclor 1254 and 1260 at concentrations exceeding KDEP’s default risk-based screening levels for non- restricted use property. The levels of PCBs were significant and covered a stretch of Wilson Creek extending approximately 1,600 linear feet. Waste Characterization/Paint Sludge Sampling Five composite samples of hardened waste material were collected during the 2010/2011 investigation. The samples were collected again in 2016 and evaluated for the same parameters as soil and sediments but using the toxicity characteristic leaching procedure (TCLP). During both events, the analyses indicated that the material did not constitute a regulatory designation as a characteristic waste. Subsequently, the waste was cleaned up and disposed of as a special waste at a permitted Subtitle D landfill in 2017. Overall, all the sampling events conducted over the FYR period indicate that apart from metals and VOCs, contamination has been minimal in groundwater and almost nonexistent in surface water. However, PCBs in Wilson Creek sediments are still a cause for concern. The PCBs were found in Wilson Creek at elevated concentrations even after the paint waste was cleaned up in early 2017. Therefore, a thorough investigation of the source of PCB contamination is warranted. Site Inspection The FYR inspection of the Site was conducted on November 29, 2017. In attendance were EPA RPM, Yvonne Jones, KDEP representatives Christoph Uhlenbruch, Frank Whitney and Shital Jiwane, and KDEP’s site maintenance contractor, Eddie Taylor (no relation to A.L. Taylor). The purpose of the inspection was to assess the protectiveness of the remedy. The participants walked the Site, assessed the condition of the landfill cap, inspected the groundwater monitoring wells, drainage ditches and Wilson creek and met with a neighboring property owner. During previous site virits, KDEP had noticed signs of ATV traffic around the Site. KDEP informed Ms. Jones that the fence was extended by about 10 feet in 2015 to deter ATV traffic and trespassing. No signs of ATV traffic were visible during this site visit. There was no “No Trespassing” sign at the front gate. Ms. Jones noted that the routine monitoring seemed adequate and the Site looked in good shape. The cap looked regularly mowed and well maintained. There were no signs of erosion. The riprap slopes of the letdown channels were intact and the channels were free of vegetation. However, Mr. Taylor stated that he had observed the cap settling at few places. He showed the areas where it had started to settle. He mentioned that he had fixed an area of minor settlement around 3 years ago. The group noticed that the cap had started to settle in the central portion near the utility poles and access road leading to the back gate. The fence around the cap was in good condition overall, although it was slightly broken near the vicinity of well ALT-10. The fence was extended in the eastern portion of the Site starting near well ALT-4 and all the way till well ALT-8. The riprap in this area was still at the same location where the original fence had been and the drainage ditch seemed to lose its boundary and direction near the fence extension. Ponding was observed near the area and berms were seen to control the runoff from the drainage ditch. Mr. Taylor indicated the area is prone to flooding during heavy rains as the area gets water from both the drainage ditch as well as overflow from the pond. Mr. Taylor shared a photograph taken during heavy rains in 2015 which showed the area under water due to nmoff. Ms. Jones was concerned about the issue and noted that she did not observe such level of ponded water during previous site visits. The drainage ditch was mostly clear of excessive vegetation except in the northern portion outside the cap, trees and shrubs had started to grow. All the groundwater monitoring wells were clearly marked and locked. Some of the locks were rusty and could not be opened. The padding around the wells was good except ALT-1 where the padding was buried under a soil layer. Casing had become loose on ALT-4. One of the wells had marks of being hit by a mower or a similar object. There was an unmarked pipe near ALT-10 and unlocked wells named ALT-DW along the northern portion of the Site which were not in use. KDEP informed Ms. Jones that the paint waste and drum carcasses in Wilson creek were removed earlier in 2017. Ms. Jones wanted to confirm whether the paint waste removal was done satisfactorily or not. The creek was mostly clear and no waste was observed in the creek except at few places small remnants of paint waste were still noticeable. The EPA and KDEP representatives also met with the neighboring property owner. He reiterated his concern, which he had also stated to KDEP during a site inspection in August 2017, that the routing of the drainage ditch towards the pond is the source for overloading the pond with sediment. This issue was also mentioned in the previous FYR interview when he claimed that the structural integrity of the pond had been affected. Ms. Jones informed him that EPA was doing a title search for the A. L. Taylor property to confirm the property boundaries. Depending on the outcome of the title search, EPA will take steps to resolve the issue. On December 7, 2017, KDEP’s Shital Jiwane and Daniel Phelps, Geologist, visited the designated site repository, Ridgway Memorial Library, located at 127 Walnut Street, Shepherdsville, Kentucky 40165. ( The library only had paper records for the Site. Cheryl Harris, KDEP, delivered a compact disc containing current site records to the library on February 7, 2018. As has been noted in the previous FYRs, the southeastern portion of the cap near the fence line has been vulnerable to ponding but it has become worse in recent times. The natural topography of the area is such that the surface water/runoff flows eastward in this direction and moves towards Wilson Creek. During the current FYR site inspection in November 2017, it was observed that the area had a substantial amount of standing water. KDEP had installed berms to improve surface drainage and contain the runoff but they were not sufficient to stop the ponding of water. The drainage ditch does not have enough riprap to reduce the flow rate of water. This area including the fence were under water due to flooding in 2015. The water overflowed near the fence line due to flooding of the drainage ditch as well as overflow from the pond before moving toward Wilson Creek. If corrective measures are not taken, the integrity of the southeastern portion of the cap may be compromised. Therefore, EPA and KDEP should initiate steps to avoid ponding in the future. VI.

Affect Current ■ Protectiveness Affect Future Protectiveness Party Responsible Oversight Party Milestone Date No EPA/State EPA/State 10/31/2019 OTHER FINDINGS In addition, the following are recommendations that were identified during the 2018 FYR, but do not affect current and/or future protectiveness: • The padding around the well ALT-1 is buried under a sediment layer requiring maintenance. • The chain link fence in the vicinity of well ALT-10 is damaged and needs to be repaired. • The surface water drainage ditch outside the cap in the northern portion of the Site shows overgrowth of trees and shrubs, potentially damaging the riprap lining of the ditch. The excessive vegetation should be removed periodically to ensure proper flow of surface water towards Wilson Creek. • For many years, the neighboring property owner has been complaining regarding damage to the pond near the Site boundary. This issue needs to be resolved. • An umnarked pipe near well ALT-10 and two wells, both marked as ALT-DW along the northern portion of the Site, should be locked and/or properly abandoned. • Surface water and sediment sampling of Wilson Creek has not been performed annually. The surface water/sedirrient sampling should follow the same schedule as groundwater sampling. • The current schedule for visual site inspections, mowing and herbicide application at the Site has yielded good results and should be continued. • Contaminant concentrations in groundwater have been relatively stable over the past years. Groundwater sampling frequency may be reduced from annual to biennial. • Signage identifying the Site as a Superfund site at the entrance road. There should be signs placed on the security fence. • Within 12-14 months of this FYR, the EPA and KDEP should initiate negotiations toward renewing the Superfimd State Contract which expires in December 2020. VII. PROTECTIVENESS STATEMENT Sitcwitic ProtectiN eness Statement Protectiveness Determination: Short-term Protective Protectiveness Statement: The remedy at the Site currently protects human health and the environment in the short term due to regular O&M and the landfill cap being in good condition. However, for the remedy to be protective in the long term, the following actions should be taken: implement measures to avoid ponding near the southeastern portion of the Site and improve drainage towards Wilson Creek; conduct additional investigation of Wilson Creek to determine source of PCBs; modify the decision document to include ICs, and implement ICs to restrict groundwater and land use at the Site.

L. Taylor is an industrial waste disposal site also known as” Valley of the Drums”. The 23-acre site is situated in a small valley in northern Bullitt County, just south of the Jefferson county line and approximately 10 miles south of the City of Louisville. The Site is approximately 1.3 miles west of interstate 65 and 1.7 miles northwest of Brooks, Kentucky off of State Highway 1020. The Site does not have a numbered street address but is located at the end of an uimamed road-36. The approximate site location is 38°04’55” north latitude and 85°42’56” west longitude. Although the Site is not located in a heavily populated area, several residences border the Site to the south and east. The nearest residence is within a few thousand feet of the Site. The Crossings golf course is located immediately south of the Site. Woods border the north and west of the Site. The Site is located in the Salt River drainage basin. Wilson Creek is a small tributary originating from a spring (or relic farm pond), south of the Site and runs along the eastern edge of the Site. The creek initially flows northward about 2.5 miles into Pond Creek. Pond Creek flows for approximately 14 miles before it drains into Salt River just above the Salt River’s confluence with the Ohio River. Wilson Creek is subject to seasonal flow conditions and is classified for recreational use. There are riprap lined ditches around the perimeter of the Site which transport runoff from the Site into Wilson Creek. EPA considers Wilson Creek as an environmentally sensitive area. D-2: Physical Site Characteristics The topography of the north-central portion of Bullitt County is characterized by steep slopes, particularly in the portion of the Bullitt County bordering Jefferson County. The A.L. Taylor site falls within this general characterization having 20 to 30 percent slopes on the western and northern sides of the Site and 10 percent on the southern and eastern sides. Most of the surface area of the Site has been graded, causing the land to slope gradually eastward toward Wilson Creek. The Site is not within any 100 year floodplain. The Site is located in the Knobs physiographic region, which is characterized by a series of erosional remnants formed of Mississippian and Pennsylvanian rocks overlying Silurian and Devonian rocks. The Mississippian rocks include limestone and siltstone with some shale beds, while the Pennsylvanian rocks include sandy limestone and sandstone, which form the cap rocks in the Knobs. The Knobs province is on the western edge of the Jessamine Dome, a structural dome, which lies along the axis of the Cincinnati Arch. The regioiial dip of the formations in the vicinity of the Site, is gentle at 2 to 4 degrees to the southwest. The New Providence Shale, the New Albany Shale, the Louisville Limestone, and the Waldron Shale underlie the Site, in descending stratigraphic order. The New Providence Shale begins as shallow as 3 feet and is weathered to a depth of 12 to 13 feet. Joints and fractures in the New Providence Shale are numerous and are 2 The next step was to establish an aceeptable method for achieving closure of the Site according to the Superflind Act. The feasibility study to compare remedial action alternatives was completed in 1982 and EPA listed the Site on NPL in 1983. In 1984, PRPs voluntarily conducted remedial investigations and developed conceptual designs for remedy at the Site. The ROD was finalized by EPA in June 1986 which identified groundwater and surface water (Wilson Creek) as potential routes of exposure to hazardous substances and presented on-site containment alternative as the most cost effective remedy for the Site. In April 1987, remedial action activities commenced with the installation of clay cap, a perimeter drainage system, monitoring wells, and a security fence. In the fall of 1988, reseeding and regrading of the cap was found to be necessary due to erosion problems. In March 1989, all remedial construction was completed. EPA performed the O&M activities at the Site till 1990 after which KDNREPC assumed the responsibility as per the superfund state contract for O&M activities signed between EPA and Commonwealth of Kentucky in 1989. The consent decree for the Site was signed in 1991 which enabled Commonwealth of Kentucky to receive funds from the cost recovery settlement with the PRPs for 29 years of routine operation and maintenance. EPA deleted the Site from the NPL in May 1996. In 2007, The EPA found hardened paint sludge and drum eareasses in Wilson Creek. The solidified paint waste was identified as non-hazardous and disposed of in a solid waste landfill in 2017.

The remedial action must achieve a level of cleanup that at least attains those requirements that are legally applicable or relevant and appropriate. Applicable requirements are those cleanup standards, standards of control, and other substantive requirements, criteria, or limitations promulgated under federal environmental or state environmental or facility siting laws that specifically address a hazardous substance, remedial action, location or other circumstance found at a CERCLA site. Relevant and appropriate requirements are those standards that, while not "applicable," address problems or situations sufficiently similar to those encountered at the CERCLA site that their use is well suited to the particular site. Only those state standards more stringent than federal requirements may be applicable or relevant and appropriate. To-be-considered (TBC) criteria are non-promulgated advisories and guidance that are not legally binding but should be considered in determining the necessary remedial action. For example, TBCs may be particularly useful in determining health-based levels where no ARARs exist or in developing the-appropriate method for conducting a remedial action. The TBCs are evaluated to determine if the selected remedy established in the ROD remains protective. ARARs were not defined for the Site in the June 1986 ROD because the Superfund Amendments and Reauthorization Act (SARA) was enacted in September 1986, and pre-SARA RODs were not required to identify ARARs within the remedy selection discussions. In addition, the 1986 ROD did not establish specific COCs nor any action levels associated with those COCs, such as Safe Drinking Water Act Maximum Contaminant Levels (MCLs). Therefore, changes in these standards cannot be evaluated at this time. G-1 Table H-1 Summary of Detected Constituents in Groundwater Monitoring Wells (2013-2017) A. L.

Unanticipated or Unusually High O&M Costs During Review Period Describe costs and reasons: In 2016, topographic survey of the Site was conducted. In 2017, the major activities were paint waste cleanup at Wilson Creek and drainage improvement in the southeastern portion of the Site. There activities were in addition to regular O&M resulting in higher costs. V. ACCESS AND INSTITUTIONAL CONTROLS 0 Applicable DN/A A. Fencing 1.

OTHER REMEDIES If there are remedies applied at the site which are not covered above, attach an inspection sheet describing the physical nature and condition of any facility associated with the remedy. An example would be soil vapor extraction. XL OVERALL OBSERVATIONS Implementation of the Remedy Describe issues and observations relating to whether the remedy is effective and functioning as designed. Begin with a brief statement of what the remedy is to accomplish (i.e., to contain contaminant plume, minimize infiltration and gas emission, etc.). Direct contact as well as migration of contaminants from the capped area is prevented. Security fence- groundwater monitoring wells and perimeter drainage ditches should be maintained. The remedy is effective and fimctioning as designed. Adequacy of O&M Describe issues and observations related to the implementation and scope of O&M procedures. In particular, discuss their relationship to the current and long-term protectiveness of the remedy. The current schedule for visual site inspections, mowing and herbicide application has been effective and should be continued. However. Wilson Creek needs to be monitored with the same fi'eauencv as groundwater. C. Early Indicators of Potential Remedy Problems Describe issues and observations such as unexpected changes in the cost or scope of O&M or a high fi"equency of unscheduled repairs that suggest that the protectiveness of the remedy may be compromised in the future. Ponding in the southeastern portion has been a cause for concern for a long time. This issue needs a more permanent solution in the near future. D. Opportunities for Optimization Describe possible opportunities for optimization in monitoring tasks or the operation of the remedy. The degradation of contaminants in groundwater at the Site is slow. Therefore, it is not necessary to monitor the Site for natural attenuation for groundwater aimually. The fi~equency of groundwater monitoring can be reduced from annual to biennial monitoring.______________________________ Site Inspection Participants: Yvonne Jones (EPA) Christoph Uhlenbruch, Shital Jiwane, Frank Whitney (KDEP) Eddie Taylor (KDEP Contractor) APPENDIX J - SITE INSPECTION PHOTOGRAPHS a ^ . __________ ir- •STM W-'^mmm ^SA ,»P^ £ ■ kSMi^S , v>. pIS;'4>-" A3^ L.^ ,. -* i'S-^, - K'.'i/b •; - n Extended fence near the eastern portion of the Site v:i\] ; V VM’»* IK*" » SslE: •''-Ip fcPI^. ■'■■ ,3jifep^^v';.> Jjgp^?gg-T'"- i«i^..-ii,. jk >fJ-.':^, ■'>.«■ .'3^’^^ ■ -i--■ :’« r’''^.,. :^ r^- '■'■ ' , ' X;' .V Berms and socks installed to control runoff from the draining ditch near fence line in the southeast portion of the Site :A ^ f.viv^ >irii^'^j^ To^ ' ’•'^i- ,..^-v-A-s^-it52*^-V:^ i ■r • •^ii^v''?*^.
