OF EACH OF THE SITES. IT IS THE CONRACTOR’S RESPONSIBILITY TO DEVELOP

THEIR OWN CONCLUSIONS REGARDING THE SITES AND THEIR PROPOSED

APPROACH BASED ON ALL AVAILABLE INFORMATION. THE DOCUMENT ABOVE ARE

NOT ALL INCLUSIVE OF AVAILABLE INFORMATION REGARDING THE SITES AT FORT

CAMPBELL.

1.1 FCPB-09 (HQAES ID 21145.1009) NBC Fire Training Area (TN)

FCPB-09 (NBC Fire Training Area) is located on the northern site of Air Assault Street between Market Garden Road and A Shau Valley Road in Tennessee. From 1980 to

1990, JP-4 jet fuel, gasoline and other hydrocarbons were poured into a metal trough and ignited for training. An RFI conducted between August 1992 and August 1993 noted that the constituents found in the groundwater correspond to those found in the groundwater from monitoring wells near the perimeter of the site. During the October

2007 sampling event, both vinyl chloride and TCE were detected at the site at concentrations slightly above their respective MCLs. The findings are consistent with post IRA analytical results dating back to 2005. Cleanup exit strategy: Annual groundwater monitoring and reporting to the state will continue, as will quarterly LUC inspections.

1.2 FCPB-26 (HQAES ID 21145.1023) Sanitary Landfills 2 & 4 (TN)

FCPB-26 addresses only SWMU 2 and 4 due to detections of vinyl chloride above the

MCL in some groundwater samples. SWMU 2 (Landfill 2) is located on the eastern side of market Garden Road in Tennessee. This landfill operated from 1965 to 1970. SWMU

2 operated from 1975 to 1981. In FY02 enhanced bioremediation was conducted at

Landfill 2 to address the chlorinated solvent contamination. SWMU 4 (Landfill 4) is located on the northeastern corner of Market Garden Road and Screaming Eagle

Boulevard in Tenessee. This site is about 20 acres and is covered with grass. It operated from 1975 to 1981. SWMU 2 has six wells and are to be sampled for VOCs.

SWMU 4 has three wells and is to be sampled for VOCs and arsenic. Cleanup exit strategy: Biennial groundwater monitoring and reporting to the states will continue, as will quarterly LUC inspections.

1.3 FCPB-38 (HQAES ID 21145.1035) Campbell Army airfield (KY)

Campbell Army Airfield is the Army's largest airfield and is located in the northeastern corner of Fort Campbell. Inventories, past practices and previous findings indicate release of a large volume of contaminants from multiple sources. An RFI for the CAAF

SWMUG was approved by KDEP in 2009, and a final CMS was approved later that year, pending the implementation of the CMI work plan. Cleanup exit strategy annual groundwater monitoring and reporting to the state will continue as will free produce recovery.

1.4 FCPB-43 (HQAES ID 21145.1040) Chromium Plating Shop (TN)

SWMU 140includes Building 7811, and inactive wastewater treatment facility (WWTF) located north of Building 7811, and a sanitary sewer line connecting Building 7811 and the inactive WWTF. Past practices at this site include the formulation of nuclear components for storage. Operations were changed in 1965 to a weapons refurbishing and metal cleaning facility, which was closed in 1993. A draft RFI/CMS was submitted to the TDEC in May 2008. The recommended remedial alternative was establishment of an “Area of Control” and LUCs, including annual groundwater monitoring for VOCs at wells. Cleanup exit strategy: Annual groundwater monitoring and reporting to the state will continue, as will quarterly LUC inspections.

1.5 FCPB-48 (HQAES ID 21145.1045) Old Skeet Range (TN)

This one-acre site was a skeet range; it is no longer in operation. It is adjacent to a community recreational area and is bounded on the north side by Fletcher's Fork Creek.

Results of the preliminary assessment (PA)/site inspection (SI) revealed levels of PAHs that pose a potential risk to human health and the environment. Due to contamination of semi-volatile compounds (SVOC) in the sediment at Fletcher's Fork Creek above the

USEPA, Region VIIII PRGs, signs and surface water sampling are required as part of the final remedy at the site. Cleanup exit strategy: Annual surface water monitoring and reporting to the states will continue, as will quarterly LUC inspections. Periodic review costs are tracked under site 21145.1035, FCPB-38.

1.6 FCPB-52 (HQAES ID 21145.1049) Oil Pits (KY/TN)

FCPB-52 (SWMU 149) is comprised of 40 abandoned oil pits and three flammable material storage sheds. Thirty-nine of the SWMU 149 site have been granted NFA status by both TDEC and KDEP. Groundwater monitoring continues at the remaining site. As per the Corrective Action Plan approved by TDEC in August 2010, a downhole absorbent sock is installed to capture free product if and when it enters the well. The sock is replaced on a quarterly basis. Cleanup exit strategy: Annual groundwater monitoring and reporting to the states will continue, as will free product recovery as needed.

1.7 FCPB-65 (HQAES ID 21145.1062) Former Skeet Ranges (TN)

These two former skeet ranges are located on Screaming Eagle Boulevard, just north of the range control. The two ranges occupied approximately eight acres and were used from the early-1940s to the 1960s for recreational skeet shooting. Contaminants of concern include PAHs from the clay skeet targets and lead from shot. Results from the

CS of September 2001 indicate that surface soil is impacted by PAHs and lead. In order to expedite addressing potential risks associated with lead and PAH contaminated soil, the Army elected to perform an IRA concurrent with the RFI to remove contaminated soil. Delineation of surface and near surface soils was performed during February 2007 and March 2007. The IRA, consisting of excavation and disposal of lead and PAH contaminated soil, was performed in May 2007 and June 2007. Following the IRA, the site has achieved NFA status for all areas located outside the fenced range control facility. Cleanup exit strategy: Groundwater monitoring and reporting to the states will continue, as will quarterly LUC inspections of soils inside the fence to prevent exposure.

1.8 CCA FTC NG (HQAES ID 21145.1071) Contaminated Tank Removal Site (KY)

Building 2996 is in an area designated for troop housing. The building had an 8,000-gallon UST fuel oil tank to supply heating oil for the building. An 8,000-gallon fuel oil tank was removed from the site on Feb. 25, 2005. Approximately 100 cubic yards of soil were removed during the UST removal project. The tanks served boilers located in building 2996. The COCs were: benzo(a) anthracene (5,800 ppb) benzo(b)fluoranthene

(5,500 ppb) benzo(k)fluoranthene (4,600 ppb) benzo(a)pyrene (6,000 ppb) chrysene

(6,400 ppb) dibenzo(ah)anthracene (1,100 ppb) ideno(1,2,3-cd)pyrene (5,000 ppb) The cancer risk was calculated using the USEPA Region IX PRG guidance in excess of 10(-

4). The West Wall soil sample was the worst. The East Wall and trench for the line removal were also contaminated above USEPA Region IX PRGs. Chillers serving the building were in the way of over-excavation of the contaminated soil. The soil should be over-excavated when the buildings are demolished and the chillers are gone. Building

2996 is not scheduled for demolition until beyond FY22.

1.9 CCA FTC-Na (HQAES ID 21145.1072) Fuel Oil Tank Contamination (KY)

The fuel oil tanks at Hammond Heights residential areas were located very close to each building near the residence entrance. The UST held fuel oil used for heating and have been out of service since the 1970s. In 2003, Solutions to Environmental

Problems, Inc. (STEP, Inc.) conducted a UST removal project at Hammond Heights as part of a facility modernization project. During this time contamination was discovered due to overfilling and leaking tanks. The project consisted of the removal of 156 USTs from the Hammond Heights buildings. The tanks were removed and over-excavated to the extent possible. The constraints were the utilities and the foundations of the housing. The state of Kentucky accepted the remedy of institutional/LUCs for the soil beneath the residence until the buildings are removed, or natural attenuation occurs.

Administrative LUCs for multiple sites are tracked under this site. Cleanup exit strategy:

Groundwater monitoring and reporting to the states will continue, as will quarterly LUC inspections of soils under buildings.

1.10 FCPB-PFAS (HQAES ID 21145.1109) PFAS (KY/TN)

Per direction from ACSIM and DoD Directives, this site was created to account for all

PFAS costs at the installation. Currently, a PA/SI is underway to identify releases of

PFAS to the environment. The cost-to-complete will be determined at a later time appropriate in the CERCLA process.

Compliance Cleanup Sites (CC)

2.1 CCS FTC-027 (HQAES ID 21145.1080) OB/OD Area SWMU 27 (TN)

SWMU 27 was a 45 acre OB/OD site. The site operated from 1943 -1997. Eighteen wells were located around the site. Only one well showed contamination of cyclotrimethylenetrinitramine (RDX) above the Region IX PRG. The primary impact area was a three to four acre area where, potential UXO remain. Cleanup exit strategy:

Biennial groundwater monitoring and reporting to the state will continue as will quarterly

LUC inspections. Periodic review costs are tracked under site 21145.1035 (FCPB-38).

2.2 CCS FTC-001 (HQAES ID 21145.1086) Abandoned Dumps 1, 3, 6, 8 (KY/TN)

SWMUs 1-6 and 8 have been grouped together under the same CLIN of the awarded

PBA contract. The SWMUG wells have indicated a release of chlorinated solvents above Region IX PRGS and MCLs. Landfill 5 was the only landfill with a permit. It was closed in 1987. All other abandoned dumps were closed prior to 1987. SWMU 1-4 are in

TN: SWMUs 5-6 are in KY. A RCRA Correction Action Permit was issued in accordance with 40 CFR 124.15 by USEPA in 1990. Cleanup exist strategy: Biennial groundwater monitoring and reporting to the state will continue, as will quarterly LUC inspections.

2.3 CCS FTC-007 (HQAES ID 21145.1088) Abandoned Dump 7 (TN)

Abandoned dump 7 was a sanitary landfill closed prior to 1986. However, waste from an old landfill (SWMU 165) was moved to Landfill 7 in 1996. A release of benzene and dichloroethene has been verified in the groundwater and levels exceed EPA region IX

PRGs, but were not in excess of MCLs. The site is a SWMU listed in the 1990 corrective action permit issued by EPA. The legal driver is the RCRA corrective action permit issued by TDEC in 2006. CLEANUP STRATEGY: TDEC requires continued biennial groundwater monitoring at this site because it is an unlined landfill with waste in place. Quarterly LUC inspection are also required. Periodic review costs are tracked under site 21145.1035 (FCPB-38). LUCs are tracked under HQAES 21145.1072 (CCA

FTC-Na).

2.4 CCS FTC-014 (HQAES ID 21145.1090) Abandoned Dump 14 Campbell Army

Airfield Landfill (KY)

The cap was restored. Chromium and lead have been above Kentucky's risk-based screening levels in the past. Continued groundwater monitoring (LTM) is required at the site. Cleanup exit strategy: KDEP requires biennial groundwater monitoring and LUCs at this site because waste is left in place and the landfill is unlined, so the potential for release exists. Periodic review costs are tracked under site 21145.1035, FCPB-38.

2.5 CCS FTC-141 (HQAES ID 21145.1091): Abandoned Dump 17 (KY)

The site is a Construction/Demolition Landfill. The site is a SWMU as identified in the

1990 corrective action permit. A risk evaluation was submitted to KDEP in April 2006 with a request for No Further Investigation and P&A of the two wells. KDEP rejected the risk evaluation. Cleanup exit strategy: The final proposed remedy is administrative

LUCs with long-term monitoring at five year intervals. Groundwater monitoring every five years and reporting to the states will continue, as will quarterly LUC inspections.

Periodic review costs are tracked under site 21145.1035, FCPB-38.

2.6 CCS FTC-00 (HQAES ID 21145.1095): Landfill 5 (KY)

This site is a unlined landfill with waste in place. The groundwater has been impacted by the landfill. Groundwater samples show exceedances of the MCL for Arsenic

(4/2005) and EPA Region IX PRGs for benzene (6/2004), 1,4 chlorobenzene (3/2005), trichloroethylene (TCE) (5/2002) and vinyl chloride (3/2005). The Commonwealth of

Kentucky currently requires continued groundwater monitoring since there has been a release from the landfill to the aquifer. The legal driver is the RCRA corrective action permit issued in accordance with 40 CFR 124.15 by EPA in 1990. Cleanup exit strategy:

Biennial groundwater monitoring and quarterly LUCs are required. When groundwater monitoring is complete eight (8) wells may be abandoned. However, indefinite monitoring may occur because waste remains in place and there is a potential for release. Periodic review costs are tracked under site 21145.1035, FCPB-38.

THEIR OWN CONCLUSIONS REGARDING THE SITES AND THEIR PROPOSED

APPROACH BASED ON ALL AVAILABLE INFORMATION. THE DOCUMENT ABOVE ARE

NOT ALL INCLUSIVE OF AVAILABLE INFORMATION REGARDING THE SITES AT FORT

KNOX.

1.1 FTK-011 (HQAES ID 21405.1002) 17 Wastewater Treatment Plant Sludge

FTK-011, the 17 Waste Water Treatment Plant (WWTP) Sludge Drying Beds (SDB) are located off of Ninth Avenue. The 17 sludge-drying beds have a total area of approximately 34,000 square feet. They were constructed in 1960 to dewater domestic sludge generated at the former

WWTP. Historical data and the results of three phases of RCRA facility investigations (RFI) have provided information on the nature and extent of soil contamination. The RFIs indicated potential risk to human health from elevated metals, pesticides, and semi volatile organic compounds in surface and subsurface soil. Kentucky Department for Environmental Protection

(KDEP) approved the CMS November 28, 2007. Remedial actions (RA) were completed in

FY08 and presented in a RA report in FY09. The area is designated as industrial use and the land use is anticipated to remain unchanged in the future. The site is on the installation's RCRA

Corrective Action Permit. Periodic reviews are performed at the site. Annual LUC inspections are performed and documented in the Fort Knox annual reports. The cleanup/exit strategy at the site is to continue monitoring, reporting, LUCs, and periodic reviews until unrestricted use / unrestricted exposure (UU/UE) is achieved.

1.2 FTK-020 (HQAES ID 21405.1005) DRMO Former Waste Oil Tank Site

FTK-020, the former Defense Reutilization and Marketing Office (DRMO) Waste Oil Tank site is located in the vicinity of Building 2952 off of Frazier Road. Aerial photographs indicate that the site was used as early as 1964 as a storage yard for Army vehicles, scrap metals, shell casings and drums. The site formerly contained a 12,000-gallon underground storage tank (UST) that stored waste oil. An RFA recommended that the tank be removed and the site cleaned up.

Multiple investigations were completed at the site and was included in a Sitewide Karst

Monitoring Program. Soil samples collected from the site indicated the presence of petroleum hydrocarbons, metals, and polycyclic aromatic hydrocarbons (PAH).The CMS was completed in

FY07 and the selected alternative consisted of LUCs, maintenance of the gravel cover, long-term inspections and maintenance, and groundwater monitoring. The cleanup/exit strategy at the site is to continue monitoring, reporting, LUCs, and periodic reviews until no further action

(NFA) is achieved.

1.4 FTKX-01 (HQAES ID 21405.1009) Closed Landfill (9th and Wilson Road)

The Closed Landfill (CLF) is located in the southeastern quadrant of the cantonment area southwest of the intersection of 9th Avenue and Wilson Road. Available historical information, including aerial photographs and old topographic map records, indicate that the landfill was active from the 1940s until 1950. Information from source-characterization activities confirmed that the landfill contents consisted of primarily inert industrial and sanitary wastes. Coal fines, slag, and flash were confirmed in some of the trenches. The results of three phases of the RFI indicated potential risk to human health from contaminants in surface soil, subsurface soil, groundwater, surface water, and sediment and to the environment from contaminants in surface soil and sediment. Remedial actions were completed in FY05 and presented in a RA report. The site is currently in the CMI(O) phase. The cleanup/exit strategy at the site is to continue monitoring, reporting, LUCs, and periodic reviews until NFA is achieved.

1.5 FTKX-02 (HQAES ID 21405.1010) Residential Landfill

Site FTKX-02, the closed Residential Landfill, is located north of the cantonment area bounded by Baker Road on the north and by Brandenburg Station Road on the west. It has two components. The combined landfills occupy approximately 285 acres of permitted area with 42 acres of residential waste and 27.4 acres of C/DD waste. The site was investigated to assess the potential for groundwater contamination from the underlying pre-1984 trench-type landfill..

The initial groundwater monitoring system consisted of five monitoring wells installed around the landfill. A first quarter sample analysis in 1993 indicated contamination in one of the five wells;

the contaminants were lead and benzene. In FY00 the final groundwater monitoring plan was submitted and baseline groundwater characterization was initiated. The evaluation of eight baseline monitoring events indicated no significant issues with organic contaminants of concern

(COC), but did identify significant background issues with metals and indicator parameters. The cleanup/exit strategy at the site is to continue monitoring, reporting, LUCs, and periodic reviews until NFA is achieved.

1.6 FTKX-10 (HQAES ID 21405.1017) Wastewater Sludge Lagoons (2)

FTKX-10, the WWTP Former Sludge Lagoons (FSL) were part of the former WWTP located in the south-central portion and along the eastern perimeter of the cantonment area. The FSL were in use from 1942 to 1960 and received partially treated sewage and other wastes from the

WWTP, allowing the sludge waste to dry. In 1980, sludge was removed from the western lagoon and the lagoon was backfilled using construction debris and soil. The lagoons are not lined.

Improper disposal of petroleum, chemicals, solvents, pesticides, and other compounds directly into the lagoons via sewer outfalls or direct discharge into the lagoons is suspected to have resulted in the release of contaminants into the lagoon surface waters and sediments. Historical data and the results of three phases of RFIs provided information on the nature and extent of soil contamination. The RFIs indicated potential risk to human health from elevated metals, pesticides, and semi-volatile organic compounds in surface and subsurface soil. The cleanup/exit strategy at the site is to continue monitoring, reporting, LUCs, and periodic reviews until UU/UE is achieved.

1.7 FTKX-21 (HQAES ID 21405.1027) Boatwright Maintenance Area Near Building 277

FTKX-21 the former Spent Solvent Storage Area, located within the Boatwright Maintenance

Area near Frazier Road, at the northern boundary of the cantonment area. This area was used for the storage of chlorinated solvents, caustics, petroleum-based fluids, and acids, and is currently used for the storage of lubricants. Surface runoff from the site is directed to a catch basin connected to an OWS. The UST is no longer present and records of its removal are not available. The OWS is still present and functional. Historical data and the results of three phases of RFIs provided information on the nature and extent of soil contamination.

Tetrachloroethene (PCE) and trichloroethene (TCE) were identified as COCs in groundwater. In

2007, the CMS and decision document (DD) selected a corrective action of biostimulation and bioaugmentation in the high-concentration portions of the plume, monitored natural attenuation

(MNA) for the low-concentration portions of the plume, and institutional controls to maintain industrial land use.The cleanup/exit strategy at the site is to continue monitoring, reporting, LUCs, and periodic reviews until NFA is achieved.

1.8 FTKX-22 (HQAES ID 21405.1028) Building T-112 UST Pesticide Rinse Tank

FTKX-22 is a former pesticide rinse tank site located behind Building 112 in the southern part of the cantonment area. Building 112 was used as an automotive maintenance facility, and later was used for mixing and formulation of insecticide and rodenticide solutions. An UST that collected the pesticide rinseate and associated piping were removed in 1988. Historical data and the results of three phases of RFIs have provided information on the nature and extent of soil contamination. The identified site-related COCs in groundwater are primarily PCE and TCE, and their degradation products. A CMS and DD were both finalized in 2007. The CMS recommended biostimulation, bioaugmentation, MNA, and interim institutional controls to address contamination in groundwater. The cleanup/exit strategy at the site is to continue monitoring, reporting, LUCs, and periodic reviews until NFA is achieved.

1.9 FTKX-40 (HQAES ID 21405.1045) UST 1473-A Site Closure

Site FTKX-40 (UST 1473A) is the location of a former 10,000-gallon gasoline UST. The site is located between Chaffee Avenue and Knox Street in the main cantonment area, in a maintained lawn adjacent to an asphalt drive. The site was part of a former gasoline fueling station. The

UST was installed circa 1947 and in use until 1986. A nearby 2,000-gallon diesel UST (UST

1473B) was used to store diesel fuel. Both USTs were removed in 1992. Several previous site investigations have been conducted. KDEP UST classification guidelines were used as guidance in assessing the nature and extent of contamination. Benzene, toluene, ethylbenzene, and xylenes (BTEX), TCE, and 1,2-DCA were identified as COCs for groundwater. A DD for Site

FTKX-40 selected an IM of MNA and interim ICs with semi-annual groundwater monitoring. LUC inspections are required annually. Because MNA has not been effective in permanently decreasing site COCs in groundwater below RA levels a new modification was approved by

KDEP in a letter dated February 11, 2019. Per the approved modification, a new IM will be developed, using the data obtained from the new downgradient well installed in 2019 and the revised conceptual site model. The cleanup/ exit strategy at the site is to continue monitoring, reporting, LUCs, and periodic reviews until NFA is achieved.

1.10 CCFTK-103 (HQAES ID 21405.1076) Multiple Heating Fuel UST Remedies

Part of the Fort Knox UST program in the past was to close numerous state exempt petroleum tank systems, some of which were heating oil tanks. Many of these sites met the applicable soil limits during closure and received an NFA letter from the state; however, some of the sites required further remediation in order to meet applicable soil levels. In FY08, the heating fuel

UST cleanup program was created to investigate 55 UST sites. In 2009 additional sampling was conducted and analyzed. Based on analytical tests of soil samples during this sampling event, it was determined that over-excavation, confirmatory sampling, and submittal of a closure report were required to close out 26 of these 55 sites. Regulated UST sites 7342.1, .2, and .3 required additional investigation to determine the extent of contamination; therefore, a new site was created; CCFTK-7342 (21405.1078). Four heating fuel USTs have not received clean closure due to the close proximity of buildings and utilities: sites 1118, 1483, 1486, and 6901. Complete close-out cannot be achieved due to proximity of buildings and/or utilities to each site. The cleanup/exit strategy at the site is to continue LUCs until building and or utilities are moved.

1.11 CCFTK-7342 (HQAES ID 21405.1078) UST 7342. 1, .2, .3

The CCFTK-7342 Site is located at the southwest corner of Ninth Avenue and Wilson Road, in the southeast quadrant of the Fort Knox cantonment area. Site CCFTK-7342 is a fueling system, used primarily for fueling military vehicles and equipment, was originally installed in

1963 and consisted of two 12,000-gallon diesel USTs, one 12,000-gallon gasoline UST and associated piping that serviced three pump islands. Site CCFTK-7342 piping and pump islands were removed in 1997 and the USTs were removed in 1998 along with an unknown volume of soil over-excavated from the tank pit. Documentation from these activities demonstrated that some concentrations of COCs BTEX and PAH remained in the soil after excavation. The former

UST pit area was not closed following the UST closure guidance and Fort Knox EMD was not able to secure NFA status from the KDEP Division of Waste Management UST Branch. An implemented RFI delineated the extent of site COCs in soil and the nature and extent of COC impacts to groundwater. Based on the RFI findings, the site was transferred from the Hazardous

Waste Branch back to the UST Branch in November 2018. The Site Investigation Report recommended NFA status. On September 12, 2019 KDEP issued an NFA determination and the site was formally closed under UST Branch guidelines. The cleanup/exit strategy at the site is to continue LUCs until the land use changes. Annual LUC inspections will be performed by a government employee and Periodic Review costs will be captured under the CLF (FTKX-01

21405.1009).

1.12 FTKX-45 (HQAES ID 21405.1088) PFAS

Per direction from Deputy Chief of Staff G-9, site created to account for all per- and polyfluoroalkyl substances (PFAS) costs at the installation. Currently a site investigation (SI) is underway to identify all releases of PFAS to the environment.

SITES AT FORT RUCKER.

1.1 FTRU-008 (SWMU-10) (HQAES 01252.1008) Landfill North Of Dilly Bridge

This site was a 10 acre landfill located in the southeast portion of FTRU on North Dilly Branch Road and east of the Engine Test Stand. The site operated as a trench and fill landfill until closure in 1970. A CMS was conducted and recommended natural attenuation with enhanced monitoring.

Natural attenuation monitoring will continue on a semiannual basis for total petroleum hydrocarbons (TPH). MNA will continue until clean-up objectives have been meet as defind in the approved CMIP. Groundwater and surface water are sampled semiannually and annually as defind in the in the approved CMIP. Once VOC concentrations have decreased below MCLs for three consecutive monitoring events in a single well, monitoring may be discontinued upon approval.

1.2 FTRU-012 (SWMU-4) (HQAES 01252.1012) Landfill Ozark City Lease SWM

This site was a trench and fill landfill of about 10 acres located on Campground Road at the northern edge of FTRU. The landfill was a municipal waste landfill which operated from 1977 to 1982. In addition to the installation, the landfill was used by the city of Ozark and Dale County to dispose of household. A CMS was conducted, and the recommendations in the CMS were for MNA with enhanced monitoring. The ADEM concurred with the recommendations of the CMS for MNA with enhanced monitoring on a semiannual basis for VOCs and metals. CMI(O)is required to conduct groundwater monitoring and to maintain access roads to monitoring wells. MNA will continue until clean-up objectives have been met. Routine cover maintenance is required.

Groundwater is sampled semiannually.

1.3 FTRU-040 (SWMU-14) (HQAES 01252.1024) Waste POL Disposal Area

This site was an unlined pit approximately 80 ft in diameter and seven ft deep. The pit was used to dispose of waste POL products such as contaminated helicopter fuel, tanker truck washouts, and possibly motor oil. Operations at this site ceased prior to 1980 and the pit was capped with clay.

Samples taken from the pit in 1980 showed traces of TCE. Both the state of Alabama and Region IV USEPA recommended closure. The phase II RFI conducted in 1997 confirmed the initial investigation results, and a CMS was recommended. The CMS recommended bioventing to digest the POL contamination. VOCs were below MCLs. In response to ADEM comments, the CMIP includes the requirement for metals sampling in groundwater. ADEM requested additional soil sampling and groundwater monitoring. The results of the groundwater monitoring results showed napthalene exceeded its MCL. New wells will be installed. LTM sampling will include metals/naphthalene.

1.4 FTRU-051 (SWMU-15) (HQAES 01252.1035) Firefighting Training Area

This site is located on Dilly Branch Road on the southeast portion of the installation. From the 1950s until 1986 the site operated an old unlined fire-training pit. Waste POL, jet propellant 4 and other fuels were poured onto a water buffer inside the pit, ignited, and extinguished. In 1994 the installation began RFI. Soil samples were collected . Sediments were sampled in the drainage ditch leading from the fire pit, and wells were installed to determine any impact to groundwater.

Further investigation at this site was required since contaminants were found in groundwater downgradient of the site and in the water discharging from the oil/water separator. A CMS recommended a removal action for both pits, the drainage ditch, and the old soil disposal area. In 1997 the USACE, Mobile District designed a soil removal and thermal desorption project for the site. This resulted in the installation successfully remediating its most heavily contaminated site.

This site is covered under a Hazardous Waste Corrective Action Permit issued by ADEM. MNA will continue until cleanup objectives have been met as defined in the corrective action permit.

1.5 FTRU-171 (SWMU-2D/AOC-P) (HQAES 01252.1095) Former Sump BLDG 955

This site was a trench and fill landfill located at the southeast corner of Hatch and Engineer Road in the southeastern area of the installation. It was approximately 40 acres and was operated from about 1950 to the early-1980s. The landfill was used to dispose of a wide variety of materials.

Groundwater monitoring wells were installed at various times throughout the life of the landfill.

During this monitoring, contamination above MCLs was detected in several wells. ADEM required the installation to prepare a groundwater corrective action plan (CAP). Preliminary analytical data collected indicated the presence of chlorinated solvents, VOCs, and metals. At that time, the contamination appeared to be migrating from the site. Preliminary data suggested the need for additional groundwater monitoring wells to further delineate the plume. In January 2001 the additional monitoring wells were installed. The CMI(O) includes maintenance, erosion control, LUCs, MNA and groundwater performance monitoring as described in the approved 2007 CMIP.

Groundwater monitoring at this site includes required monitoring at AOC-P, which is downgradient and contiguous of FTRU-171.

1.6 FTRU-174 (AOC-E) (HQAES 01252.1098) Oil Gas Station Site UST

FTRU-174 (AOC-E) is a former gas station site. The site was given an NFA Status in Fort Rucker's initial corrective action permit. However, the RFA that was conducted in 2013 by ADEM recommended that the site be investigated to determine if USTs are present at the site. Following the recommendations of the RFA, ADEM included FTRU-174 in the corrective action permit that was renewed in 2016, and required that confirmatory sampling be performed. An investigation found that there were no USTs at the site; however, underground piping that carried fuel from an AST to fuel dispensers was found. An RFI will be completed to determine nature and extent of contamination and help determine future remedial action, if necessary.

1.7 FTRU-175 (AOC-F) (HQAES 01252.1099) Old Gas Station Site UST

FTRU-175 (AOC-F) is a former gas station site. The site was given a NFA status in Fort Rucker's initial corrective action permit. However, the RFA that was conducted in 2013 by ADEM recommended that the site be investigated to determine if USTs are present at the site. Following the recommendations of the RFA, ADEM included FTRU-175 in the corrective action permit that was renewed in 2016 and required that confirmatory sampling be performed. A contract was awarded in 2016 to investigate the site to determine if USTs were present. The investigation found that there were no USTs at the site; however, underground piping that carried fuel from an AST to fuel dispensers was found. An RFI will be completed to determine nature and extent of contamination and determine future remedial action.

1.8 AOC-S PCE (HQAES 01252.1115) In Groundwater near SWMU-8

An RFI for AOC-S, which is near and upgradient of a solid waste management unit, was completed in 2012. The RFI showed that groundwater within the investigation area was impacted with concentrations exceeding the ADEM maximum contaminant level (MCL) of 5 micrograms per liter (µg/L). The apparent source of the PCE was a washrack that was operated from the 1950s to the late-1980s. PCE was not detected in soil in the vicinity of the washrack, indicating that the source and may have been removed during removal of the washrack. The maximum PCE concentration exceeds the MCL. An approved CMS/CMIP recommended installation of a PCE treatment technology followed by monitored natural attenuation and risk assessment.

Groundwater monitoring under the CMI(O) was initiated in December 2013. The CMI report was submitted to ADEM for review in January 2014 and included an environmental use restriction document as required by ADEM.

1.9 CC-AOC-A1 (SWMU-97) (HQAES 01252.1117) Buried Debris Behind School

This site is currently the location of Fort Rucker's Primary School. During 2012, Fort Rucker was in the preliminary stages of designing a consolidated school. In the Historical Photo Analysis Report that was produced in 1995, the site is noted as a junkyard in a 196. The existing school was constructed in the mid-1970s. An environmental assessment that was performed which resulted in concentrations of arsenic which exceeded USEPA's residential screening levels (RSL) and the ADEM's preliminary screening values (PSV) for residential soil. However, the concentration for arsenic was below or equal to the background concentration est ablished for Fort Rucker. Multiple semi-volatile organic compounds (SVOC) were detected in the samples, five of which exceeded the RSLs and PSVs for residential soil (benzo(a)anthracene, benzo(a)pyrene, benzo(b)fluoranthene, dibenzo(a, h)antracene and indeno(1,2,3-cd)pyrene. An RFI was completed to determine nature and extent of contamination and help determine future remedial action and is pending review. A CIMP is under review but not approved.

1.10 SWMU-5 Active Surface Dumping Landfill

SWMU 5 is south of Engineer Road and north of the reservation boundary. The landfill was opened in the 1940’s and closed in 1952. It is approximately 8 acres.
