ICs have been implemented as part of the selected corrective measures for each site. This inspection was conducted as required by TEAD's Resource Conservation and Recovery Act (RCRA) Post Closure Permit for Post Closure Monitoring and Corrective Action of SWMUs, issued June 25, 2005. As required by the permit, TEAD will conduct semi-annual inspections to ensure the continued effectiveness and retention of all implemented ICs. The inspection documented by this report was conducted by the TEAD Environmental Office between March 1l and March 17, 2008. Figure 1 provides the location of each SWMU inspected. The SWMUs addressed during this inspection include: 2.0 INSPECTION RESULTS 2.1 SWMU lb - Burn Pads 2.1.1 Site Background The Burn Pad is located in a small erosional valley approximately 2,000 feet east of the Main Demolition Area (SWMU 01). Site activities began prior to 1959 and reportedly were SWMU 01b - Burn Pads SWMU 34 - Pesticide Storage and Handling Area SWMU 01c - Trash Burn Pits SWMU 37 - Contaminated Waste Processor SWMU 03 - X-Ray Lagoon SWMU 42 - Bomb Washout Facility, Building 539 SWMU 04 - Sandblast Areas (Bldgs 600, 615 and 617)SWMU 45 - Storm Water Discharge Area SWMU 11 - Laundry Effluent Ponds and Waste Piles SWMU 46 - Used Oil Dumpster (Building 611) SWMU l2lL5 - Pesticide Disposal ArealSanitary Landfill SWMU 48 - Old Dispensary SWMU 19 - AED Demilitanzation Test Facility SWMU 49 - Storm Water/Industrial Waste Water Piping SWMU 20 - AED Deactivation Furnace Site SWMU 50 - Condensate Drains (Bldgs 613 and 619) SWMU 2l - Ammo Deactivation Furnace Site SWMU 5l - Alodine Drying Beds SWMU 25 - Battery Shop SWMU 52b - Disposal Trenches SWMU 26 - DRMO Storage Yard SWMU 54 - Sandblast Areas (Building 611 and 637) SWMU 29 - Drum Storage Area SWMU 56 - Gravel Pit Disposal Area discontinued before 1977. The area has since been re-graded and revegetated, and is no longer used for demilitarization activities. SWMU 01b previously consisted of a 300 by 100 foot cleared pad where propellant was burned in open trenches and projectiles were flashed. Based on historical aerial photographs from 1959, 1966, and 1978, five separate trenches were located in the pad. No permanent structures were associated with operations at the Burn Pad. 2.1.2 Site Investigations During the completion of the RCRA Facility Investigation (RFI), test pits were excavated and soil samples were collected to determine whether contamination existed due to previous historical activities. One explosive was identifred as a Contaminant of Potential Concern (COPC) in surface soil. In subsurface soil, metals, explosives, and dioxins/furans were identified as COPCs. Unexploded ordnance (UXO) was also encountered in the subsurface soils during the RFI. Future investigations to be conducted at the site under the Army's Military Munitions Response Program (M[,m.P) are planned for this site. A Site Inspection (SI) of the site was completed lin2007 with a recommendation to conduct additional investigations of the site under a Remedial Investigation/Feasibility Study (RVFS). MMRP activities will be conducted under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) process. 2.1.3 Site Risk The human health risk assessment (RA) identified cancer risks greater than the target value of 1x10-6 for hypothetical futtre onsite adult residents, and an elevated hazard index (HI) for hypothetical future onsite child residents. No elevated cancer risks or HIs were identified for current workers or future construction workers, In addition, all projected blood lead levels were below the Center for Disease Control (CDC) target of 10 pgldl-. As UXO was found on the site, and explosivehazard is also known to be present. The ecological RA concluded that the COPCs detected in soil at SWMU 01b present a low ecological risk. 2.1.4 Current Land use The current land use for SWMU 01b is industriaVmilitary. The site is located within the boundaries of the active operating Open Burning/Open Detonation (OB/OD) area. No demilitarization activities are conducted on SWMU Olb. 2.1.5 Future Land Use There is no planned change in land use for SWMU 01b, and no planned demilitarization activities are expected to occur on the site. 2.1.6 Corrective Measures No Contaminants of Concem (COCs) were identified at SWMU 01b. Therefore considering the results of the human health RA, ICs in the fonn of land use controls (LUCs), excavation restrictions, site fencing, and signage were selected as the corrective measure for this site. The LUCs are intended to prohibit futrue residential use or development of the site. The land use contols also include a notation that prohibits disturbance of the site unless a UXO survey and clearance is conducted. Site fencing is intended to prohibit unauthorized access, and signage warning of the UXO potential and access restrictions are required. 2.1.7 Site Visit and Visual Inspection A visual site inspection of SWMU 01b (figure 2) was conducted on March 17,2008. The site remains under the control of the Anny, and is located within the boundaries of the active open burning/open detonation area. To the south of the site, and outside of the installation, a new county road has been constructed along the installation boundary connecting State Road 36 to the Mormon Trail. The primary purpose of the new road is for access to a gravel mining operation located south of the installation. The active open buming/open detonation area is fenced with warning signage. The site remains unused and undeveloped. At the time of this inspection there were not indications of disturbance of the site. 2.2 SWMU lc - Trash Burn Pits 2.2.1 Site Background The Trash Bum Pits are located in the southwest corner of TEAD, in a small erosional valley 2,000 feet east of the Main Demolition Area (SWMU 01), and adjacent to the Bum Pad (SWMU 01b). The site is an open, graded, and vegetated area of approximately 45 acres, with no pennanent structures. Disposal and waste buming activities occurred at SWMU 01c from approximately 1959 to the 1980s. Disposal pits were reportedly several hundred feet long, 8 to 10 feet wide, and 4 to 6 feet deep. 2.2.2 Site Investigations Test pits were excavated and soil samples were collected to determine whether contamination existed on the site due to previous historical activities. Containers and other wastes were identified within test pits excavated in the areas of waste disposal activities dating from the 1950s to 1960s. Burn areas on the ground surface were encountered in areas of waste disposal activities dating from the 1970s to 1980s. Metals and explosives were identified as COPCs in surface and subsurface soils. Dioxins/furans were identified as COPCs in subsurface soil only. UXO was also encountered during the RFI. Future investigations to be conducted at the site under the Army's Military Munitions Response Program (MMRP) are planned for this site. A Site Inspection (SI) of the site was completed in 2007 with a recommendation to conduct additional investigations of the site under a Remedial Investigation/Feasibility Study (RVFS). MMRP activities will be conducted under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) process. 2.2.3 Site Risk The human health hypothetical future onsite residents and construction CDC target of 10 prgldl-,. The ecological RA low ecological risk. 2.2.4 Current Land Use RA identifred cancer risks greater than the target value of lxl0-6 for adult residents, and elevated HIs for hypothetical future onsite child workers. In addition, all projected blood lead levels were below the concluded that the COPCs detected in soil at SWMU 01c present a The current land use for SWMU 01c is industrial. The site is located within boundaries of the active operating Open Burning/Open Detonation (OB/OD) area. demilitarization activities are conducted on SWMU 01c. 2.2.5 Future Land Use There is no planned change in land use for SWMU 01c, and no planned demilitarization activities are expected to occur on the site. 2.2.6 Corrective Measures At SWMU 01c, one explosive was identified as a COC in surface soil, and metals were identifred as COCs in subsurface soil..Howevetr, the COC exposure point concentrations (EPCs), which correspond to a weighted site wide concentration are below corrective action objectives. Also, the elevated HI for future construction workers is due to the presence of manganese in soil at concentrations that are less than the average for the western United States. Therefore considering the results of the human health RA, ICs in the form of land use controls (LUCs), excavation restrictions, site fencing, and signage were selected as the corrective measure for this site. The LUCs are intended to prohibit future residential use or development of the site. The the No land use contols also include a notation that prohibits disturbance of the site unless a UXO survey and clearance is conducted. Site fencing is intended to prohibit unauthorized access, and signage waming of the UXO potential and access restrictions are required. 2.2.7 Site Visit and Visual Inspection A visual site inspection of SWMU Olc (figure 3) was conducted on March 17,2008. The site remains under the control of the Army, and is located within the boundaries of the active open burning/open detonation area. To the south of the site, and outside of the installation, a new county road has been constructed along the installation boundary connecting State Road 36 to the Monnon Trail. The road is used primarily to access a gravel mining operation which is located south of the installation boundary. The active open burning/open detonation area is fenced with warning signage. The site remains undeveloped and unused. At the time of the inspection there were no indications of disturbance of the site. 2.3 SWMU 03 -X-Rav Lasoon 2.3.1 Site Background The X-Ray Lagoon is a 75 by 35 foot by 6 foot deep lined lagoon which fuom L974 through 1990 received rinse water from film washing, and diluted spent developer and fixer solutions from the Film Processing Facility @uilding 1223). Little information is available concerning the history of operations prior to 1974, though Building 1223 was the site of the former Redeye Missile Rebuild Facility. 2.3.2 Site Investigations Soil, sediment, and groundwater samples were collected to detennine if contamination existed from previous activities. Metals were detected in lagoon sediments, in soil from a standing liquid area, in sludge from an adjacent septic tank. Metals were also detected in various subsurface soil samples at levels exceeding background concenftations and were identified as COPCS. 2.3.3 Site Risk The human health RA identified cancer risks greater than the target value of lx10-6 for the hypothetical future onsite residential child and adult receptors, and an elevated HI for adult and child receptors. No elevated cancer risks or HIs were identified for actual current and likely future Depot personnel. Risks and HIs are from soiVsediment exposure. No ground water exposure occurs. The site wide ecological RA concluded that the COPCs detected in soil at SWMU 03 present a low ecological risk. 2.3.4 Current Land Use The current land use at SWMU 03 is industriat/military. The site is located within the boundaries of the secure ammunition storage area. The lagoon remains unused and does not receive any waste water. 2.3.5 Future Land Use There is no planned change in land use at SWMU 03, and no planned reactivation of the lagoon. 2.3.6 Corrective Measures No COCs were identified in soil samples at SWMU 03. Elevated levels of metal in groundwater have been demonstrated to be due to corrosion of stainless steel well materials, not to site related activities. Therefore, considering the results of the human health RA, ICs in the form of LUCs were selected as the corrective measure for this site. The LUCs are intended to prohibit future residential use or development of the site. In addition to the application of LUCs, corrective measures implemented at the site included the abandonment of several monitoring wells, as ground water monitoring is no longer required. The abandonment of five monitoring wells located on the site was completed in October 2005. One monitoring well was left in place at the site to facilitate future water level measurements if required. 2.3.7 Site Visit and Visual Inspection A visual site inspection was conducted at SWMU 03 (figure 4) on March 17, 2008. The lagoon remains under the control of the Arrny. Buildings located to the south of the lagoon are currently active and are utilized for conducting ammunition maintenance and shrpping operations. There are no indications of discharges to the lagoon from these facilities. The lagoon remains unused and there were no visible signs of discharge to the lagoon. The site is fenced with waming signage. 2.4 SWMU 04 - Sandblast Areas (Buitdinss 600.615 and 617) 2.4.1 Site Background SWMU 04 is located on the Base Realignment and Closure (BRAC) parcel, within the former TEAD industrial area. It includes sandblast areas located outside of Buildings 600, 615, and 617. Degreasing, sandblasting, paint stripping, and painting operations were conducted at these facilities. Degreasing wastes, as well as wastes from stripping and painting operations, were drummed and removed for offsite disposal. 2.4.2 Site Investigations Surface and subsurface soil samples were collected to detennine if contamination existed on the site as a result of the historical sandblast operations. At building 600, metals were detected in surface soil at levels exceeding background concentrations and were identified as COPCs. Volatile organic compounds (VOCs) and semi volatile organic compounds (SVOCs) were also detected in surface soils, and were identified and COPCs. At buildings 615 and 617, metals were detected in surface soils and subsurface soils at levels exceeding background concentrations and were identified as COPCs. VOCs and SVOCs were also identified as COPCs as they were detected in both surface and subsurface soils. Additional investigations are currently being conducted at building 615 as part of the on- going SWMU 58 RFI to determine if VOCs remaining in the vadose zollie are a source of ground water contamination. Sampling results obtained to date indicate that a significant amount of contamination remains in the vadose zore at this site that may require the implementation of additional corrective measures. 2.4.3 Site Risk At building 600, tle human health RA identified cancer risks greater than the target value of 1x10-6 for the hypothetical future onsite residential child and adult receptors, and an elevated HI greater than 1.0 for the child receptor. No elevated cancer risks or HIs were identified for the actual current and reasonably anticipated future industrial worker, or for the future construction worker. At buildings 615, and 617, the human health RA identified cancer risks greater than the target value of lxl0-6 for the hypothetical future onsite residential child and adult receptor. No elevated HIs were identified. In addition, for the future residential child, the percentage of receptors exceeding the CDC blood lead level guidelines for lead in soil was greater than the 5 percent target. No elevated cancer risks or HIs were identified for the actual current and reasonably anticipated future industrial worker, nor for future construction worker receptors. The site wide ecological RA concluded that the COPC detected in soil and buildings 600, 615, and 617 present a low ecological risk. 2.4.4 Current Land Use SWMU 04 is located on properly currently owned by the Utah Industrial Depot. The current land use of site is industrial. 2.4.5 Future Land Use There is no planned change in land use at SWMU 04. The reasonably anticipated future land use remains industrial. 2.4.6 Corrective Measures At building 600, one polycyclic aromatic hydrocarbon (PAH) and lead were identified as COCs in surface soil samples, but at concentrations only slightly above corresponding CAOs and in isolated samples. The EPC for each COC, which represents a risk based exposure level, was compared to the industrial CAO. The PAH EPC was below its corresponding CAO, indicating no risk derives from that compound for an industrial use. The EPC for lead is just above its CAO, and it only occurred in one sample. Therefore, considering the results of the human health RA, ICs in the forrn of deed restrictions were selected as the corrective measure for this site. The deed restrictions me intended to prohibit future residential use or development of the site. The deed restrictions have been incorporated in the property deed for this site, and are legally binding. Deed restriction on the BRAC property are governed by the associated environmental covenants, conditions, and restrictions (CCRs). At building 615 and 617, two PAHs, lead, and chromium were identified as COCs in surface soil samples. However, the EPCs are below the CAOs for the metals and one PAH. The EPC for the remaining PAH is at a level such that it does not pose a risk to an industrial worker. Therefore, considering the results of the human health RA, ICs in the form of deed restrictions were selected as the corrective measure for this site. The deed restrictions are intended to prohibit future residential use or development of the site. The deed restrictions have been incorporated in the property deed for this site, and are legally binding. Deed restriction on the BRAC property are goveflred by the associated environmental covenants, conditions, and restrictions (CCRs). 2.4.7 Site Visit and Visual Inspection A visual site inspection was conducted at Building 600 (frgure 5) on March 11,2008. The facility is currently occupied and is utilized by the Utah Industrial Depot as their facility maintenance shop and storage area. A visual site inspection was conducted at building 615 (frgure 6) on March 11, 2008. The facility is currently being utilized by a private entity for sandblast and painting operations. General house keeping by the current occupant is considered very poor, as was noted in the previous inspections. Signifrcant quantities of sandblast media and paint overspray were observed in the area surrounding the facility. The site is currently zoned by Tooele City for Industrial Use. No residential use or development of the site has occurred, nor is it planned. The area srurounding the facility is considered a probable source area contributing to the contamination of SWMU 58 which is currently under investigation. Several stages of investigation and sampling have been conducted around and beneath the building as part of those investigations. Furttrer corrective action may be required at the site upon completion of the SWMU 58 studies. A visual site inspection was conducted at building 617 (frgure 7) on March 11,2008. Building 617 is currently unoccupied and not being used. The sandblast booth located adjacent to and south of building 617 has been removed from the site. No residential use or development of the site has occurred, nor is it planned. 2.5 SWMU 11- Laundrv Effluent Ponds and Waste Piles 2.5.1 Site Background The laundry effluent pond was constructed n lg47 for the collection of laundry and shower water from building 1267, and boiler water from building 1237. SWMU ll consists of the laundry pond, sewage pond, sand pit, septic tank, leach field, and the waste pile area located to the east. Discharge to the laundry effluent pond was discontinued in 1990; however, it continued to receive boiler water during the winter months until 1995. The benned, unlined pond is approximately 16 feet deep, 80 feet wide, and 100 feet long. The sewage pond, constructed between 1978 and 1990 for the collection of waste water from buildng 1267, is benned, unlined, and is 8 feet deep, 120 feet wide, and 134 feet long. However, it was never used, and any water observed in the pond was likely the result of rain, snow melt, or infiltration from the adjacent septic system. A shallow sand pit, located next to the new TNT washout pond, was reportedly excavated to provide cover material for the old TNT washout ponds when they were capped. The septic tank is located south of the sewage pond; with the leach field reportedly beneath the pond. From 1948 through 1990, the septic tank and leach field reportedly received waste water for buildings 1245, 1267, and 1254. ' Waste piles identified in the fall of 1992 were reported to contain wood fragments, metal banding, electrical wiring, metal shavings, and old automotive parts. 2.5.2 Site Investigations Sediment, surface and subsurface soil samples were collected to determine if contamination existed on the site as a result of historic activities. Elevdted metals and SVOCs were detected in laundry effluent pond and sewage pond sediment and in surface soil, while septic tank sludge and subsurface soil contained elevated levels of metals, SVOCs, and VOCs. These contaminants were identified as COPCs. Total petroleum hydrocarbons (TPH) and elevated metals were detected in soil near the waste piles and were identified as COPCs. Elevated metals and SVOCs were detected in laundry effluent pond surface water, while the sewage pond water contained VOCs, SVOCs, an explosive, and metals at concentrations exceeding background. These contaminants were identified as COPCs. 2.5.3 Site Risk The human health RA identified cancer risks greater than the target value of 1x10-6 for the hypothetical future onsite residential child and adult receptors, and elevated HIs for both receptors. No elevated cancer risks or HIs were identified for actual current and likely future Depot personnel. However, blood lead levels for resident and depot personnel exceeded the CDC target of 10 pgldl. The site wide ecological RA concluded that the metals detected in soil at SWMU 1l present a moderate ecological risk. 2.5.4 Current Land Use The current land use at SWMU 11 is industrial. The paved areas within the boundaries of the SWMU are currently being used as part of the SWMU 10 soil composting facility that was constructed in the summer of 20A7 south of the laundry pond. The compositing facility extends east into the area of the SWMU 11 waste piles. 2.5.5 Future Land Use There is no anticipated change of land use at SWMU 11. The use of the site will remain industriaVmilitary. Over the next twelve months, a portion of the SWMU as well as an area adjacent to the SWMU will be utilized for the composting of explosives contaminated soil from SWMU IO. 2.5.6 Corrective Measures Within the ponds (laundry effluent and sewage), no COCS were identified for surface water. Metals were detected near the sewage pond (9 feet below surface) at a concentration above the corresponding CAO; however, because no one is expected to contact material this deep during construction, and the EPC is well below the CAO, metals were not identified as a COC. 10 SVOCs were detected in surface soil samples at the laundry effluent pond, but at a concentration only slightly above the corresponding CAO and only in one sample. Concentrations of two SVOCs, which were detected in sediment samples collected from a small area within the sewage pond exceeded their respective CAO and were identified and COCs. Corrective measures implemented at SWMU 1l consisted of the excavation and off site disposal of soil contaminated with metals from the Waste Pile Area, and soils contaminated with SVOCs from the laundry effluent pond. The excavation of soil was driven by the CAOs for industrial use of the site. In addition to the soil removal, ICs in the form of LUCs were implemented as part of the corrective measure for this site. The LUCs are intended to prohibit future residential use or development of the site. 2.5.7 Site Visit and Visual Inspection A visual inspection of SWMU 11 (figures 8 and 9) was conducted on March 17,2008. The site remains under control of the Anny. The lagoons were empW, and there was no visible sign of discharge to them. There are no known plans for development of the lagoon site, with the exception of the SWMU 10 corrective measures which are underway and will continue for approximately twelve months. The waste pile excavations, which were not re-seeded during completion of corrective measures have significantly re-vegetated naturally. The vegetation cover is now adequate and no signs of erosion were observed. 2.6 SWMU 12115 - Pesticide Disposal Area/Sanitarv Landfill 2.6.1 Site Background The Sanitary Landfill (SWMU 15) covers approximately 70 acres and was used for the disposal of hazardous and non-hazardous waste dating backto 1942. The waste was builed in trenches or placed in natural depressions, and covered with soil from the surrounding area. The southerr portion of the SWMU was closed in the 1980s. The north and central portions of the landfill were closed to ttre disposal of domestic waste in the spring of 1994; however, this portions of the landfrll continued to accept construction debris, asphalt, and asbestos until the spring of 1996. The landfill reportedly handled conventional sanitary waste (e.g., scrap metal, tires, paper products, general refuse, and scrap wood), untreated paint sludge, grease and oil, and paper type filters for separating PCBs from oils to be reused in electrical transformers. Waste products from metal plating operations, painting operations, battery acid containers, pesticide and herbicide containers, asbestos containing materials, and ethylene glycol were also disposed of at the landfill during the 1940s, 50s, and 60s. Hazardous was not disposed of in the landfill after October 1980, when TEADs Hazardous Waste Management Plan was implemented. t1 I The Pesticide Disposal Area, SWMU 12 is located within the boundaries of SWMU 15. SWMU 12 consists of a trench where drums and containers containing residual amounts of pesticides were drained prior to disposal. This activity was reported to have ceased in the early 1980s. In 1993, TEAD was instructed by the Utah Departrnent of Environmental Quality (UDEQ) to complete site closure as part of the RCRA Post Closure activities. In addition, at the time of landfill closure, a determination was made that the requirements in Utah Administative Code (UAC) R3l5-302-3 and its parts would apply, and that corrective action would be implemented under TEAD's Post Closure Monitoring and Corrective Action Permit. 2.6.2 Site Investigations During previous investigations, groundwater, soil gas, and soil samples - surface and subsurface were collected to detennine if contamination existed on the site as a result of historic disposal activities. COCs for the site were identified by comparing the maximum concentration of each COPC identified in the Phase II RFI Report to its respective quantitative CAO. Based on this evaluation, the COCs for surface soil at SWMU l2ll5 were detennined to be arsenic, chromium, dieldrin, and polycyclic aromatic hydrocarbons (PAHs) including benzo(a)anthracene, benzo(a)pyrene, benzo(b)fluoranthene, and indeno(1,2,3-cd)pyrene. The COCs identified for subsurface soil at SWMU l2ll5 are arsenic, benzo(a)pyrene, and dibenz(a,h)anthracene. TCE was also detected in groundwater at SWMU 12/15, at a maximum concentrations exceeding 850 pglL, and has also been identified as a COC for the site. 2.6.3 Site Risk The human health RA conducted on SWMJ 12115 considered the hypothetical residential scenario even though there are plans to use the site for other that military/industrial purposes. Under the current and reasonably anticipated future military land use scenario, no excess cancer risks above 1x104 or an HI above 1.0 were identified at the site. Under the construction worker scenario, no excess cancer risks above lxl0a were identified. However, and HI above 1.0 was identified. Under the hypothetical future residential land use scenario, cancer risks greater that lxl0-6 and an HI greater than 1.0 were identified. The site-wide ecological risk assessment determined that compounds detected in soil at SWMU 12/15 poterfiially present an unacceptable ecological condition, but these compounds are not pervasive. t2 2.6,4 Current Land Use The current land use for SWMU l2ll5. The site is located within the boundaries of the installations administrative area. The site is closed and no longer used for disposal purposes. 2.6.5 Future Land Use There is no anticipated change of land use at SWMU l2ll5. The use of the site will remain industrial. 2.6.6 Corrective Measures Corrective measures implemented at SWMU 12/15 linc}uded improvements to the soiV vegetative cover, and groundwater monitoring. In addition to these activities, ICs in the fonn of LUCs were implemented as part of the corrective measure for this site. The LUCs are intended to prohibit future residential use or development of the site. These corrective measures were designed to mitigate human health risk posed by direct contact to the contaminants found in the surface and subsurface soils at the site. Groundwater contaminants underlying the site are being addressed under the depot-wide groundwater investigation that also includes SWMUs 2, the industrial waste lagoon and ditches, and 58, the industrial area ground water sources and northeast boundary plume. Specific elements of the corrective measures implemented at SWMU 12115 included excavating native soil from non-impacted areas within the SWMU to use as cover material; collecting loose surface litter and consolidating it at specified low areas; covering exposed debris and consolidated surface litter at selected sites with approximately 24 in. of soil; re-seeding areas of disturbed soil; repairing the SWMU 12115 boundary fence; and inspecting and maintaining the landfill cover on an annual basis. Fieldwork associated with implementation of the corrective measures was completed in October 2005. 2.6.7 Site Visit and Visual Inspection This inspection addressed only the implementation of land use controls. The inspection maintenance and repair of other ICs (engineering controls) is conducted on an annual basis by the U.S. Army Corps of Engineers. The results of that inspection are documented in a separate report during the fall of each fall. A visual inspection of SWMU 12/15 (figare 10) was conducted on March 17, 2008. The site remains under confrol of the Army. The compost and seed that were applied upon completion of the corrective measures at the site, have resulted in a significant growth of vegetation. The vegetative cover is now well established and is functioning as intended to prevent any erosion of the site. The site remains fenced with locked gates that are controlled by the TEAD Environmental OfIice limiting access to the site. Inspection of the site fencing and l3 signage is conducted annually and is known to remain in good condition. Land Use Controls implemented as part of the corrective measure for this site remain protective. No residential use or development of the site has occurred, nor is it planned. 2.7 SWMU 19 - AED Demilitarization Test Facilitv 2.7.1 SiteBackground The AED Demilitarization Test Facility was constructed in 1973, and is located southwest of the ammunition storage area in a remote and undeveloped area of TEAD. It consists of six small buildings, two burning pans, and a series of protective earthen revetments. Operations at SWMU 19 include experimental or pilot testing to determine if new design demilitarization equipment is functional, and to develop operational procedures and techniques for ammunition maintenance, handling and demilitarization equipment that is designed and built at TEAD. Live ammunition and propellants are commonly utilized at the site during , which has included propagation tests, function tests, barricade testing for explosive lines, and burning in pans. 2.7.2 Site Investigations Surface and subsurface soil samples were collected at the site to detennine if contamination of the site had resulted for historical test and evaluation operations conducted on the site. Metals were detected in surface soil at levels exceeding background concentrations and were identified as COPCs. Explosives and SVOCs were also detected in surface soil, and were identified as COPCs. No contaminants were detected at concentrations exceeding background concentrations in subsurface soil. 2.7.3 Site Risk The human health RA identified cancer risks greater than the target the hypothetical future on site residential child and adult receptors, as well both receptors. No elevated cancer risks or HIs were identified for the reasonably anticipated future industial or construction worker receptors. The site wide ecological RA concluded that the COPCs detected in present a moderate ecological risk. 2.7.4 Current Land Use value of 1x10-6 for as elevated HIs for acfual current and soil and SWMU 19 O t4 The current land use of SWMU 19 remains industrial. The site remains active and continues to be used for evaluation and testing of ammunition handling and demilitarization systems. 2.7.5 tr'uture Land Use There is no anticipated change of land use at SWMU 19. The test and evaluation activities being conducted on the site will continue for the foreseeable future. 2.7.6 Corrective Measures No COCs were identified in soil samples at SWMU 19. Therefore, considering the results of the human health RA, ICs in the form of LUCs were selected as the corrective measure for this site. The LUCs are intended to prohibit future residential use or development of the site. 2.7.7 Site Visit and Visual Inspection A visual site inspection was conducted at SWMU 19 (figure 11) on March 13,2008. The site remains an active military test facility where experimental or pilot testing is done to detennine if new design demilitarization equipment is functional, and to develop operational procedures and techniques. The area surrounding the facility remains undeveloped, and is used primarily for grazrng. Land Use Controls implemented as the corrective measure at this site remain protective. No residential use or development of the site has occurred, nor is it planned. 2.8 SWMU 20 - AED Deactivation tr'urnace Site 2.8.1 Site Background The AED Deactivation Furnace Site (SWMU 20), is located in the eastern portion of the installation, along the road that links the AED Demilitarization Test Facility (SWMU 19) and the Bomb Shell Reconditioning Bldg (SWMU 23). The facility has been active since 1970. The site includes Buildings 1351, 1352, 1355,1356 and former building 1354. However, only buildings 1351 and 1352 are related to site activities. This facility is used to test demilitarization procedures for various munitions; it is not used as a production facility. Building 1351 includes a deactivation furnace (rotary-kiln type), a flashing furnace and a large pollution contol system (installed n 1976). Building 1352 is a small storage building. The entire facility sits on an asphalt pad approximately 200 by 225 ft in size. The asphalt pad is approximately 3 inches thick, underlain by a gravel base course approximately 9 inches thick. A small area of the western corner of the asphalt surface was once used to store drummed residue, and is referred to as the former Hazardous Waste Holding Area. The project site is surrounded by a four-foot high barbed wire security fence, with trvo metal gates providing access from the adjacent road t5 2.8.2 Site Investigations Surface and subsurface soil samples were collected at the site to determine if contamination of the site had resulted for test and evaluation operations conducted on the site. Antimony and lead were detected in surface soil at levels exceeding background concentrations and were identifred as COPCs. 2.8.3 Site Risk The human health RA conducted at the site determined that there were no elevated cancer risks or hazardous for the military or construction worker on the site. However, elevated risks, hazards, and blood lead levels were identified for the hypothetical future onsite resident. The site wide ecological RA concluded that the COPCs detected in soil and SWMU 20 present a moderate ecological risk. 2.8.4 Current Land Use The current land use of SWMU 20 remains industrial. The site remains active and continues to be used for evaluation and testing of ammunition handling and demilitarization systems. 2.8.5 Future Land Use There is no anticipated change of land use at SWMU 20. The test and evaluation activities being conducted on the site will continue for the foreseeable future. 2.8.6 Corrective Measures Based on the results of the of the human health risk assessment, the corrective measures for the consisted of placing an asphalt cap over the areas where metal contamination was present, along with implementing land use controls prohibiting the residential use of development of the site. 2.8.7 Site Visit and Visual Inspection This inspection addressed only the implementation of land use controls. The inspection maintenance and repair of other ICs is conducted on an annual basis by the U.S. Arrry Corps of Engineers. The results of that inspection are documented in a separate report each fall. t6 A visual site inspection was conducted at SWMU 20 (figure 12) on March 13, 2008. The site remains an active military test facility where experimental or pilot testing is done to detennine if new design demilitarization equipment is functional, and to develop operational procedures and techniques. In the surrmer of 2007, a underground heating oil tank located on the site was closed and removed. The tank was located in an area east of the portion of the site where contaminated soil was covered with an asphalt cap. Closure and removal of the tank had no impact on the implemented corrective measures. The area surrounding the facility remains undeveloped, and is used primarily for grazrng. Land Use Controls implemented as a component of the corrective measure at this site remain protective. No residential use or development of the site has occurred, nor is it planned. 2.9 SWMU 21 - Ammo Deactivation Furnace Site 2.9.1 Site Background The Ammo Deactivation Furnace Site is an arnmunition demilitarization production facility constructed about 1955. It occupies 0.7 acre in the southwestern portion of TEAD and currently operates under a RCRA Part B permit. The areas that are being proposed for corrective measures were contaminated prior to the facility becoming a perrnitted unit. Current operations do not add to the previous conta:nination. Building 1320 contains a rotary-kiln fumace that is used to deactivate small arms ammunition, primers, and fuses. Air pollution contol equipment was installed around 1975 to treat emissions from the furnace. Incinerator residue (ash and metal debris) is collected at the south end of the furnace and loaded into 55-gallon drums for temporary storage. Open staging areas for support equipment and drums are located around the outside of the building. These areas are partly paved with asphalt and partly covered with gravelly soil. 2.9.2 Site Investigations Soil samples were collected at analyzed at the site to detennine if contamination of the site existed from historical operations. Elevated levels of metals, dioxins/furans and explosives were identified as COPCs in surface soil. 2.9.3 Site Risk The human health RA identified unacceptable cancer risks for hypothetical future onsite adult residents. Elevated HIs were identified for hlpothetical future onsite child residents, current Depot personnel, and future construction workers. In addition, all projected blood lead levels were greater than the CDC target of 10 pgldl-. The sitewide ecological risk assessment determined that SWMU 2l poses a potentially unacceptable ecological risk. t7 2.9.4 Cwrent Land Use The current land use of SWMU 21 remains industrial. The site remains active and continues to be used for evaluation and testing of ammunition handling and demilitaization systems. The deactivation furnace located on the site has undergone several modifications/upgrades over the past year. Some of these upgrades have resulted in the need to cut into the asphalt cap. All soil and asphalt removed during these upgrades has been managed as a hazardous waste. The asphalt cap has been repaired and maintained to ensure the effectiveness of the cap. 2.9.5 Future Land Use There is no anticipated change of land use at SWMU 21. The conventional ammunition demilitarization activities being conducted on the site will continue for the foreseeable future. 2.9.6 Corrective Measures Based on the results of the of the human health risk assessment, the corrective measures for the consisted of placing an asphalt cap over the areas where unacceptable contamination was present, along with implementing land use controls prohibiting the residential use of development of the site. 2.9.7 Site Visit and Visual Inspection This inspection addressed only the implementation of land use controls. The inspection maintenance and repair of other ICs is conducted on an annual basis by the U.S. Army Corps of Engineers. The results of that inspection are documented in a separate report each fall. A visual site inspection was conducted at SWMU 21 (frgure 13) on March 13, 2008. The site remains an active military conventional arnmunition demilitaization facility which is operated under a RCRA Part B permit for the demilitarization of small arms and other ammunition components. The area surrounding the facility remains undeveloped, and is used primarily for grazing. Land Use Controls implemented as a component of the corrective measure at this site remain protective. No residential use or development of the site has occurred, nor is it planned. 2.10 SWMU 25 - Batterv Shop 2.10.1 Site Background The Battery Shop, located in Building L252, was used for the maintenance and repair of vehicle and forklift batteries from 1980 to 1993. Site features included two wash-down pads (wooden and metal) located northeast of Building 1252, a discharge pipe from the building, and a drainage ditch used to collect wash-down water from the pads as well as discharge from the Battery Shop. Spend battery acid and wash-down water were discharged to the ditch through site operations. Beginning in 1982, these liquids were neutralized with sodium bicarbonate or sodium hydroxide. The shop floor was washed down daily using sodium bicarbonate, which was discharge to the ditch until 1990. 2.10.2 Site Investigations Previous investigations conducted at this site consisted of the collection of sediment, surface and subsurface soil samples. Metals were detected in near surface soil in the drainage ditch area at levels exceeding background concentrations and were identified as COPCs. 2.10.3 Site Risk The human health RA identifred cancer risks greater than the target value of lx10-6 for the hypothetical future onsite residential child and adult receptors, and elevated HIs for both receptors. Elevated His were identified for the actual current and likely future depot personnel. The site wide ecological RA concluded that the COPCs detected in soil at this SWMU did not present an unacceptable ecological risk. 2.10.4 Current Land Use The current land use of SWMU 25 remains industrial. Currenfly no activities are being conducted on the site. 2.10.5 Future Land Use The future anticipated land use at SWMU 25 will remain industrial. 2.10.6 Corrective Measures Metals were identified as COCs in near-surface soils. Concentrations of these metals were present at maximum concqrtrations above their respective CAO. Therefore, considering 19 the results of the human health RA, corrective measures implemented at the site consisted of the excavation of contaminated soil and off-site disposal at a permitted TSDF. In addition to the soil removal, ICs in the form of LUCs have been applied to the site to prevent future reside'ntial use and development of the site. 2.10.7 Site Visit and Visual Inspection An visual site inspection of SWMU 25 (figure 14) was conducted on March 13, 2008. The site is fenced with waming signage. The site remains under contol of the Anny and is undeveloped. During implementation of corrective measures, the area of excavation was compacted but not re-seeded. Natural revegetation of the site is occurring, but at a slow rate. There are no indications of significant erosion on the site, even though vegetative cover of the site is minimal. 2.11 SWMU 26 - DRMO Storase Yard 2.ll.l Site Background The DRMO Storage yard is located within the BRAC parcel in the former TEAD industrial area. It is a 66-acre salvage yard loeated in the eastern section of the former TEAD industrial area. The site is flat and unpaved, with fencing around the perimeter. SWMU 26 was historically used by TEAD for the temporary storage of surplus military materials. The site became active between 1953 and 1959. 2.11.2 Site Investigations Previous investigations at the site consisted of the collection of surface and subsurface soil samples. Metals were detected in surface soil at levels exceeding background concentrations and were identified as COPCs. VOCs and SVOCs were also detected in surface soil, and were identified as COPCs. 2.11.3 Site Risk The human health RA identified cancer risks greater than the target value of 1x10-6 for the hypothetical future onsite residential child and adult receptors, and elevated HIs for both receptors. In addition, the percentage of future residential child receptors exceeding the CDC blood lead levels guideline for lead in soil was greater than the target. No elevated cancer risks or HIs were identified for the actual current and reasonably anticipated future industrial worker, or for the future construction worker receptor. 20 O 2.11.4 Current Land Use The current land use at SWMU 26 is industrial. The majority of the site is currently being used for storage by multiple Utah Industrial Depot tenants. Smaller areas of the site are being utilized as an automobile wrecking yard. 2.11.5 Future Land Use There is no planned change in land use on SWMU 26. The reasonably anticipated future land use for the DRMO Yard will remain industrial. 2.11.6 Corrective Measures PAHs were identified as COCs in surface soil at SWMU 26,btt at concentration only slightly above corresponding CAOs and in one isolated sample. The EPCs for the PAH are at levels such that they do not pose a risk to an industrial worker. Thus, the corrective measures implemented at the site consist of ICs in the form of deed restrictions. The deed restrictions imposed are intended to prevent residential use or development of the site. The deed restrictions have been incorporated in the property deed for this site, and are legally binding. Deed restrictions on the BRAC properly are governed by the associated environmental covenants, conditions, and restrictions (CCRs). 2.11.7 Site Visit and Visual Inspection A visual site inspection of the former DRMO Storage Yard, SWMU 26 (figures 15) was conducted on March 11,2008. The site is currently utilized for industrial and commercial storage. Activities on the site include a vehicle wrecking yard, storage of miscellaneous industrial equipment. The area surrounding SWMU 26 to the norttr, east and south remains undeveloped. Warehouse storage west of the site is maintained by the Army through a lease back agreement with Utah Industrial Depot for 6 warehouses. Deed restrictions implemented as the corrective measure at this site remain protective. Tooele City zoning identifies the site for industrial use. No residential use or development of the site has occured, nor is it planned. 2.12 SWMU 29 - Drum Storase Area 2.12.1 Site Background SWMU 29 is located on the BRAC parcel in the forrrer TEAD industrial area. The site was used to store empty drums prior to being returned to the originating supplier of the contents. The drums were reportedly stored upside down to allow residual material to drain from the container. SWMU 29 consists of two distinct separate areas. The norlhem section of SWMU 29 2t is a triangle shaped area of approximately 5 acres. A 1953 aerial photograph of this area shows drums stored in the area, while aerial photographs taken in 1959 and, 1966 indicate that the drums were removed and the area was unoccupied. The southern section of SWMU 29 covers approximately 25 acres and is primarily covered with gravel and broken asphalt. Three buildings (Buildings 576, 589, and 591) exist on the site. Aerial photographs taken in 1953, 1959, 1966 and 1981 all show the presence of drums, cylinders, tank trucks, and lumber. Additionally, on the 1959 and 1966 aerial photographs, a portion of the southem section was labeled as the "pesticide storage lof'. 2.12.2 Site Investigations Previous investigations at SWMU 29 consisted of the collection of surface and subsurface soil samples. Metals were detected in the surface and subsurface soil at levels exceeding background concentrations and were identified as COPCs. Also, SVOCs, pesticides, and TPH were identified as COPC in surface and subsurface soil. 2.12.3 Site Risk The human health RA identified cancer risks greater than the target value of 1xl0-6 for the hypothetical future onsite residential child and adult receptors,'and elevated HIs for both recqrtors. No elevated cancer risks or HIs were identified for the current and likely future industrial worker, or for the future construction worker receptors. 2.12.4 Current Land Use The current land use of SWMU 29 remains industrial. Building 589, located on the southern portion of the SWMU is currently leased by the Army for mission related activities. 2.12.5 Future Land Use There is no planned change in land use for SWMU 29. The reasonable anticipated future land use remains industial. 2.12.6 Corrective Measures One PAH was identified as a COC in surface soil at SWMU 29,btt at a concentration only slightly above corresponding CAOs, and in one isolated sample. The EPC for the PAH is at a level such that it does not pose a risk to an industrial worker. Thus, the corrective measures implemented at the site consist of ICs in the form of deed restrictions. The deed restictions imposed are intended to prevent residential use or development of the site. The deed restrictions have been incorporated in the property deed for this site, and are legally binding. Deed 22 restrictions on the BRAC property are governed by the associated environmental covenants, conditions, and restrictions (CCRs). 2.12.7 Site Visit and Visual Inspection A visual site inspection of SWMU 29,the Drum Storage Area (figure 16) was conducted on March 11, 2008. From the time of transfer of this site in 1998 through2004, the South area of SWMU 29 was utilized by the Army through a leaseback agreement as a recycling center. In 2004, recycling activities conducted on the site were terminated, and all recyclable materials were removed from the site. In 2005, the Army used building 587, located on the site as an asserrbly area for 5 ton truck annor kits that were being fabricated by TEAD. There were not Army mission activities being conducted on the site at the time of this inspection. The site remains under the control of the Army through the lease back agreement. The north section of SWMU 29 remains undeveloped. Deed restrictions implemented as the corrective measure at this site remain protective. The site is currently zoned by Tooele City for industrial use. No residential use or development of the site has occurred, nor is it planned. 2.13 SWMU 34 - Pesticide Handline and Storase Area 2.13.1Site Background The Pesticide Hapdling and Storage Area consist of building 518 and a bermed concrete pad on the south side of the building. This SWMU is located in the administration area of the active portion of TEAD. The facility is surrounded and secured by a chain-link fence. The area enclosed by the fence is approximately 75 by 75 feet (0.13 acres). Building 518 was used from 1942 arfil the mid 1990s for the storage of pesticides and herbicides, and for the preparation of application mixtures. The bermed concrete pad was used for loading sprayer trucks with these mixtures and for rinsing containers. From about 1980 to 1989, pesticide wastes from operational activities at SWMU 34 were disposed of at an offsite TSDF. Drains from building 518 reportedly connected to an 8 inch underground pipe that discharged to the Storm Water Discharge Area (SWMU 45). 2.13.2 Site Investigations Previous investigation conducted at SWMU 34 consisted of the collection of surface and subsurface soil samples. Metals and pesticides were detected in both surface and subsurface soil and were identified as COPCs. 2.13.3 Site Risk 23 The human health RA identified cancer risks greater than the target value of 1x10-6 for hypothetical future onsite adult residents, and an elevated HI for hypothetical future onsite child residents. No elevated cancer risks or HIs were identified for current Depot personnel and future constructions workers. In addition, all projected blood lead levels were below the CDC target of 10 pg/dl-. 2.13.4 Current Land Use The current use of SWMU 34 is industrial. Building 518, located on the site is utilized for storage purposes. Application and mixing of pesticides for TEAD is currently conducted by a contract company. Small quantities of pre-mix materials are periodically stored in the building. Drains in the building have been plugged to prevent further releases. 2.13.5 Future Land Use There are no planned changes in land use for SWMU 34. Continued industrial storage activities are expected to continue at the site for the foreseeable future. 2.13.6 Corrective Measures At SWMU 34, metals and pesticides were identified and COCs in surface soil. Although the EPCs for pesticides were greater than their CAOs, the resulting human health risks were determined to be acceptable. Nevertheless, because of the presence of several "hotspots" where the concentrations of the COCs exceeded their CAOs by an order of magnitude, and considering the results of the RA, corrective measures implemented at the site consisted of the excavation of contaminated soil and off-site disposal of the soil at a permitted TSDF. In addition to the soil removal, ICs in the fonn of LUCs have been applied to the site to prevent future residential use and development of the site. 2.13.7 Site Visit and Visual Inspection A visual site inspection was conducted at SWMU 34 (figure 17) on March 17, 2008. The site remains an active army facility used for storage of small quantities of herbicides and pesticides. There is no indication of any spills or releases at the site. The surrounding area consists of industrial type activities which include a fabrication shop, roads and grounds storage yard, and carpenter shop. Land use controls implemented as part of he corrective measures for this site remain protective. No residential use or development of the site has occurred, nor is it planned. 2.14 SWMA 37 - Contaminated Waste Processor 24 2.14.1 Site Background The CWP consists of one large building (Building 1325), a smaller storage building, and adjacent staging and storage areas. The furnace, used to burn waste, was fired by heating oil from an underground storage tank located south of the building. The facility itself, including the surrounding paved staging areas, is approximately 150 feet by 125 feet in size. A four-foot high barbed wire fence surrounds the facility. Since its installation in approximately 1980 and until it was closed in 1990, the CWP was primarily used for flashing scrap metal and incinerating pentachlorophenol (PCP)-treated wooden crates, general packaging materials (dunnage), scrap resins, and fabric contaminated with explosives. This CWP was a batch-type basket furnace, rather than a rotary kiln type used elsewhere at TEAD. In addition, the CWP was not used for demilitarization of munitions. Air pollution control equipment, installed during construction of the furnace, included a cyclone, gas cooler, and bag-house. When the CWP was operating, all metal debris were certified as clean and sent to the Defense Reutilization and Marketing Office (DRMO) storage yard for salvage. Incinerator ash, cyclone dust, and bag-house dust were drummed as hazardous waste and sent to the 90-day Storage Yard pending analysis and disposal. 2.14.2 Site Investigations Previous investigations at SWMU 37 consisted of the collection of surface and subsurface soil samples. Metals, SVOCs, dioxins/furans were identified as COPCs. 2.14.3 Site Risk The human health RA identified cancer risks greater than the target value of 1x10-6 for hypothetical future onsite adult residents, and an elevated HI for hypothetical future onsite child residents. No elevated cancer risks or HIs were identified for current Depot personnel or future construction workers. Blood lead levels were not evaluated for any receptor at SWMU 37. 2.14.4 Current Land Use The current land use of SWMU 37 remains industrial. The fumace which was previously installed in the facility for buming and flashing dunnage has been removed from the building. 2.14.5 Future Land Use There is no planned change in land use at SWMU 37. The site will continue to be utilized for Depot mission activities for the foreseeable future. 2.14.6 Corrective Measures 25 At SWMU 37 SVOCs and dioxins/furans were identified as COCs in surface soil. The SVOC EPC exceeded the CAO. However the SVOCs were only detected in 2 of 27 samples, with only on sample exceedi.g the CAO. The EPC for dioxins/furans was only slightly greater than its CAO. Therefore, considering the results of the human health RA, ICs in the fonn of LUCs were selected as the corrective measure for this site. The LUCs are intended to prohibit future residential use or development of the site. 2.14.7 Site Visit and Visual Inspection A visual site inspection was conducted at SWMU 37 (frgure 18) on March 13, 2008. The site is currently an active facility being utilized for ammunition recycling operations. During the inspection there were no signs of spills or releases at the site. Vegetation surrounding the area is healthy and has not been stressed. There is no planned change in land use at the site. The land use controls implemented as the corrective measure at the site remain protective. No residential use or development of the site has occurred, nor is it planned. 2.15 SWMU 42 - Bomb Washout Facilitv. Buildinq 539 2.15.1 Site Background The Bomb Washout Facility is located in the southeastern portion of TEAD, north of the Administration Area. Until recently, it was used for storage. The building previously contained a demilitarization furnace for small anns munitions. From the early 1940s to 1960, projectiles from small arms were bumed in the furnace; lead was reclaimed in troughs located beneath the fumace. Because the smokestack did not have air pollution contuols, heavy particulates setfled into a "drop-out box" located on the roof. The furnace was dismantled in 1960. When Building 539 was cleaned, washwater was discharged via a steel-lined concrete flume that extends from the northeast corner of the building. The flume runs east-west approximately 10 feet north of the building and discharges to an open ditch to.the west. The ditch extends approximately 600 feet to a fonner unlined holding pond south of the main line railroad tracks. The pond, which is currently overgrown, is 50 feet in diameter and 1 to 2 feet deep. 2.15.2 Site Investigations Previous investigations at SWMU 42 consisted of the collection of surface and subsurface soil samples. Metals and explosives were identified as COPCs in surface and subsurface soil. Dioxins/furans were identified as COPCs in surface soil only. Munitions components were also encountered during site investigations. 2.1,5.3 Site Risk 26 The human health RA identified unacceptable cancer risks for hypothetical future onsite adult residents. Elevated HIs were identified for hypothetical future onsite child residents, current Depot personnel, and future construction workers. In addition, all projected blood lead levels were greater than the CDC target of 10 mg/dl. The ecological RA concluded that the COPCs detected in soil at SWMU 42 present a potentially unacceptable ecological risk. 2.15.4 Current Land Use There is no anticipated change of land use at SWMU 42. The site will remain under the control of the military for foreseeable future. Additional investigations of the site along with possible removal actions will be completed under the Army military munitions response program as munitions components have been identified on the site. 2.15.5 Future Land Use There is no planned change in land use at SWMU 42. The site will continue to be utilized for Depot mission activities for the foreseeable future. 2.15.6 Corrective Measures This corrective measures alternative implemented at SWMU 42 consists of the installation and annual inspection/repair of a soil cover cap and liner over the areas of soil contamination to prevent human exposure and contaminant migration, site fencing and signage, and land use controls prohititing residential uso or development of the site. Contaminated soil from several isolated hot spots was excavated and placed within the former holding pond area and covered. 2.15.7 Site Visit and Visual Inspection This inspection addressed only the implementation of land use controls. The inspection maintenance and repair of other ICs is conducted on an annual basis by the U.S. Army Corps of Engineers. The results of that inspection are documented in a separate report each fall. A visual site inspection was conducted at SWMU 42 (figtxe 19) on March 17, 2008. The site is located in an undeveloped area of the installation, that in the past has been utilized intennittently for grazing. In the fall of 2006, the soil cover cap was revegetated using a compost and seed mix. Germination of the seed and the establishment of a vegetative cover has been slow due to low amounts of precipitation. Even though establishment of a vegetative cover has been slow, minimal erosion of the soil cover has occurred. Vegetation surrounding the area that was covered is healthy and has not been stressed. There is no planned change in land use at 27 the site. The land use controls implemented as the corrective measure at the site remain protective. No residential use or development of the site has occurred, nor is it planned. 2.16 SWMU 45 - Storm Water Discharqe Area 2.16.1, Site Background The Storm Water Discharge Area occupies roughly 2 acres and is located approximately 2500 feet northwest of the TEAD administration area. It consists of an unlined earthen basin as associated pipelines from the administration area's storm water collection system. Storm water has been discharged to SWMU 45 since TEAD's constructionh1942. The storm drain system consists of approximately 10,000 linear feet of subsurface pipelines. Although no industrial operations have been conducted on the site, the discharge area has historically received discharges from a carpenter shop, sign shop, motor pool, rail shop, and other such operations. 2.16.2 Site Investigations Previous investigations consisted of the collection of surface water, sediment, surface soil, and subsurface soil samples. Metals were ide,ntified as COPCs in surface and subsurface soil. Other COPCs include inorganics, SVOCs, and VOCs in surface water, and metals in sediment. 2.16.3 Site Risk The human health RA identified cancer risks greater than the target value of 1xl0-6 for hypothetical future onsite adult residents, and an elevated HI for hypothetical future onsite child residents. No elevated cancer risks or HIs were identified for current Depot personnel or future construction workers. In addition, the projected blood lead level for hypothetical future child residents is greater than the CDC target of 10 pgldl-. The ecological RA concluded that the site poses a moderate ecological risk, but the risk is not unacceptable, and does not warrant corrective measures to reduce the ecological risk. The ecological RA also concluded that corrective measures, if performed, would damage valuable wildlife habitat. 2.16.4 Current Land Use The current land use of SWMU 45 is industrial. The site still acts as a stonn water outfall that is managed under the installation storm water pollution prevention program. 28 2.16.5 Future Land Use There is no planned change in land use for SWMU 45. The reasonably anticipated future use of the site will remain industrial for the foreseeable future. 2.16.6 Corrective Measures No COCs were identified at SWMU 45. Therefore, considering the results of the human health RA, ICs in the form of LUCs were selected as the corrective measure for this site. The LUCs are intended to prohibit future residential use or development of the site. 2.16.7 Site Visit and Visual Inspection A visual site inspection of SWMU 45 (figure 20) was conducted on March 17,2008. The site remains under contol of the Army. The outfall collects storm water discharged from the Tooele Army Depot Administration Area. Discharge from the outfall to the collection area is managed through the installations stonn water discharge permit. Routine sarnpling is conducted under the requirements of this permit. Vegetation at the site is healthy and shows no signs of sfress. 2.1.7 SWMU 46. Used Oit Dumnster (Buitdinq 611) 2.17.1 Site Background The used oil dumpster located at the northern end of building 611, located on the BRAC parcel was used to collect waste oil from maintenance operations. The dumpster was routinely emptied, and the oil was taken offsite for disposal. 2.17.2 Site Investigations Previous investigations consisted of the collection of surface and subsurface soil samples. At building 6ll, metals were detected in surface soil at levels exceeding background concentrations, and were identified as COPCs. VOCs, SVOCs, and TPH were identified ad COPCs in surface soil, and VOCs and TPHC were identified as COPCs in subsurface soil. 2.17.3 Site Risk The human health RA identifred no cancer risks for any receptor at the building 6ll dumpster location. It did however, identiff an elevated HI for the hypothetical future residential child receptor. 29 The site wide ecological RA concluded that the COPCs detected in soil at this dumpster area presented a low ecological risk. 2.17.4 Current Land Use The current land use of the dumpster location at building 611 is industrial. Building 611 is currenfly unoccupied and not in use. The dumpster has been removed, and no waste oil collection is being conducted at site. 2.17.5 Future Land Use There is no planned change in land use at the SWMU 46 location. 2.17.6 Corrective Measures Two COCs were identified in surface soil samples at this dumpster location. TPHC was identified in several surface soil samples at concenffations exceeding Utah's 10,000 pg/g screening level. Metals were also detected at a maximum concentration exceeding the corresponding CAO. Therefore, considering the results of the human health RA, corrective measures implemented at the site consisted of the excavation of contaminated soil and off-site of the soil at a permitted TSDF. In addition to the soil removal, ICs in the form of LUCs have been applied to the site to prevent future residential use and development of the site. 2.17.7 Site Visit and Visual Inspection A visual site inspection was conducted at SWMU 46, building 611 (figure 2l) on March 17,2008. Building 611 is currently unoccupied and not being used. The used oil dumpster located at the north end of building 611 has been removed from the site. The area surrounding building 611 is currently being used for industrial purposes. Deed restrictions implemented as part of the corrective the corrective measure at this site remain protective. Tooele City zoning of the site is industrial. No residential use or development of the site has occurred, nor is it planned. 2.18 SWMU 48. Old Dispensarv 2.1E.1 Site Background The Old Dispensary, building 400 was located approximately 300 feet northwest of the existing TEAD medical clinic. Building 400 was located on approximately 8.2 acres, and was 30 demolished when the current medical facility was constructed in the early 1980s. Building 400, and other smaller buildings located on the site were constructed in 1945, and originally served as the installations administrative building. Building 400 was later converted to a dispensary (medical facility) and included operating rooms, a sterilization room, X-ray rooms, examination rooms, and a dental office. Discharges of X-ray development solutions were reportedly discharged to the storm water collection system located on the property. 2.18.2 Site Investigations Previous investigations at SWMU 48 consisted of the collection of surface and subsurface soil samples. Metals, pesticides, and SVOCs were identified as COPCs in shallow soil. 2.1E.3 Site Risk The human health RA identified cancer risks greater than the target value of lx10-6 for hypothetical future onsite adult residents, and an elevated HI for hypothetical future onsite child residents. No elevated cancer risks or HIs were identified for current Depot personnel and future construction workers. The ecological RA concluded that the COPCs detected in soil at SWMU 48 present a low ecological risk. 2.18.4 Current Land Use The current land use of SWMU 48 is industrial. The site is open space which was not redeveloped following closure and demolition of the old dispensary. 2.18.5 Future Land Use There is no planned change in land use for SWMU 48. The anticipated land use will remain industrial for the foreseeable future. 2.18.6 Corrective Measures No COCs were identified at SWMU 48. Therefore, considering the results of the human health RA, ICs in the form of LUCs were selected as the corrective measure for this site. The LUCs are intended to prohibit future residential use or development of the site. 31 2.18.7 Site Visit and Visual Inspection A visual site inspection was conducted at SWMU 48 (figure 22) onMarch 17, 2008. The site remains under the contol of the Army. The site is located northwest of the current TEAD Health Clinic and is currently undeveloped. Vegetation on the site is healthy and shows no sign of stress. No signs of erosion are apparent on the site. The land use controls implemented as the corrective measure at the site remain protective. No residential use or development of the site has occurred, nor is it planned. 2.19 SWMU 49 - Storm Water/Industrial Waste Water Pipine 2.19.1 Site Background SWMU 49 is located on the BRAC parcel in the former TEAD industrial area. The SWMU consists of the existing storn water system piping and outfalls located throughout the fonner industrial area. The site also includes building 609, a former steam cleaning and radiator repair facility located in the southern section of the fonner industrial area. The storm water system includes approximately 15,000 feet of interconnected pipes. The main arteries run east to west. Secondary pipes run perpendicular to the main arteries and interconnect at road intersections throughout the area. From the late 1940s until 1988, the piping system collected industrial waste water, commingling it with storm water. Because of the large area occupied by the storm water/industrial waste water piping, SWMU 49 was evaluated as nine separate areas as listed below: Sewer Line - Southern Area Sewer Line - Cental Area Sewer Line -Northerr Area Building 609 B Avenue Outfall G Avenue Outfall H Avenue Outfall J Avenue Outfall K Avenue Outfall 2.19.2 Site Investigations Previous investigations conducted at SWMU 49 consisted of the collection of sediment, surface soil, and subsurface soil samples. . In the Sewer Line - Southem Area, Sewer Line - Central Area, and Sewer Line - Northern Area metals and SVOCs were identified as COPCs. Surface soils were not evaluated, and the piprng system is located below ground, and any release would have occured in the subsurface. 32 At Building 609, metals and VOCs were identified as COPCs in surface soil, and SVOCs were identified as COPCs in subsurface soil. Metals and SVOCs were identified as COPCs in surface soil at the B Avenue Outfall, G Avenue Outfall, H Avenue Outfall, and K Avenue Outfall. No COPCs were identified in subsurface soil. At the J Avenue Outfall, SVOCs were identified as COPCs in surface soil. No COPCs were identified in subsurface soil. 2.19.3 Site Risk The human health RA conducted on the Sewer Line - Southern'Area, Sewer Line - Central Area, and Sewer Line Northern Area identified elevated HIs for onsite adult and child residents. No elevated cancer risks or HIs were identifred for future construction workers. In addition, risks and hazards were not calculated for actual current and anticipated future industrial use, because these receptors are exposed to surface soil only, and surface soil was not analyzed in this area. No ecological RA was performed for these area, and surface soils were not evaluated. At Building 609, then"-* health RA identified elevated HIs for onsite adult and child residents. No elevated cancer risks or HIs were identified for current and future industrial workers, or future construction workers. No ecological RA was perforned for Building 609 as suitable ecological habitat does not exist. At the B Avenue Outfoll, the human health RA identified elevated cancer risks and His for onsite adult and child residents. No elevated cancer risks or His were identified for actual and future industrial workers or future construction workers. In addition the projected blood lead level for child residents is greater that the CDC target of l0pg/dl. All other blood lead levels are below the target value. The site wide ecological RA classified the I Avenue Outfall, as presenting a moderate but not unacceptable ecological risk. At the G Avenue Outfall, H Avenue Outfall, J Avenue Outfall, and K Avenue Outfall, the human health RA identified elevated cancer risks and His for onsite adult and child residents. No elevated cancer risks or His were identified for actual and future industuial workers or future construction workers. The site wide ecological RA classified the B Avenue Outfall, H Avenue Outfa.ll, J Avenue Outfall, and K Avenue Outfoll, as presenting a moderate but not unacceptable ecological risk. 2.19.4 Current Land Use The current land use of SWMU 49 is industrial. The former TEAD industrial area, excess under BRAC 93 is being redeveloped and a commercial industrial park. 33 2.19.5 Future Land Use There is no planned change in land use for SWMU 49. Redevelopment of the area as and industrial park will continue for the foreseeable future. 2.19.6 Corrective Measures Metals were identified as a COC in subsurface soil at the Sewer Line - Southern Area. However, lead was detected above its CAO in one subsurface soil sample only, and the EPC for lead in subsurface soil was well below the screening level. Thus, the corrective measures implemented at the site consist of ICs in the form of deed restrictions. The deed restrictions imposed are intended to prevent residential use or development of the site. The deed restrictions have been incorporated in the property deed for this site, and are legally binding. Deed restrictions on the BRAC property are governed by the associated environmental covenants, conditions, and restrictions (CCRs). Two SVOCs were identified and COCs in subsurface soil at the Sewer Line - Central Area. However, both were detected at maximum concentrations only slightly above corresponding CAOs and at two locations only. The EPCs for both SVOCs are below their CAOs. Therefore, the corrective measures implemented at the site consist of ICs in the form of deed restrictions. The deed restrictions imposed are intended to prevent residential use or development of the site. The deed restrictions have been incorporated in the property deed for this site, and are legally binding. Deed restrictions on the BRAC property are governed by the associated environmental covenants, conditions, and restrictions (CCRs). No COCs were identified at the Sewer Line - Northern Area, Building 609, B Avenue Outfoll, H Avenue Outfall, J Avgnue Outfoll, or K Avenue Outfall. Therefore, the corrective measures implemented at the site consist of ICs in the form of deed restrictions. The deed restrictions imposed are intended to prevent residential use or development of the site. The deed restrictions have been incorporated in the property deed for this site, and are legally binding. Deed restrictions on the BRAC property are governed by the associated environmental covenants, conditions, and restrictions (CCRs). Three SVOCs were identified as COCs in surface soil at the G Avenue Outfall. The EPCs for each exceeded their respective CAOs in five out of six samples along the outfall ditch. For this reason, the corrective measures implemented at the site consisted of the excavation and offsite disposal of contaminated soil, along with ICs in the form of deed restrictions. The deed restrictions imposed are intended to prevent residential use or development of the site. The deed restrictions have been incorporated in the property deed for this site, and are legally binding. Deed restrictions on the BRAC property are governed by the associated environmental covenants, conditions, and restrictions (CCRs). 34 2.19.7 Site Visit and Visual Inspection A visual site inspection of SWMU 49 (figure 23) was conducted on March 11,2008. SWMU 49 includes all storm waster piping located within the Utah Industrial Depot. The Utah Industrial Depot is being developed as an industrial park, and is zoned for industrial or commercial use. No residentially zoned areas exist within the park. At the time of the inspection, there were not indications of any recent repair, removal, or modifications to the system. The deed restriction implemented as part of the corrective measures for this site remain protective. Current Tooele City zoning for the site is for industrial use. 2.20 SWMU 50 - Compressor Condensate Drain (Bldss 613 and 619) 2.20.1 Site Background Large air compressors associated with the vehicle maintenance mission of TEAD were located in Buildings 613 and 619. Condensate collected in the receiver tank was typically discharged at each location into a partially buried 55 gallon drum with a perforated base. The effluent flowed from the receiver through the gravel filled drum into underlying soils. The compressor condensate drain at Building 613 was located along the west exterior of the building. The drain at Building 619 was located along the north wall of the central wing of the facility. 2.20.2 Site Investigations Previous investigations at SWMU 50 consisted of the collection of surface and subsurface soil sarnples. At Building 613, metals and SVOCS were identified and COPCs in subsurface soil. At Building 619, YOCs and SVOCS were identified in surface soil, and metals and SVOCs were identified as COPCs in subsurface soil. 2.20.3 Site Risk The human health RA conducted on Building 613 identifred elevated HIs for onsite adult and child residents. No elevated cancer risks or HIs were identified for future construction workers. Risks and hazards were not calculated for actual current or fufure industrial workers as these receptors are exposed to surface soil only. At Building 619, the human health RA identified elevated cancer risks and HIs for onsite adult and child residents. No elevated cancer risks or HIs were identified for actual current and future industrial workers or construction workers. 2.20.4 Current Land Use 35 The current land use of both building 613 and 619 are industrial. The drains have been removed and closed at both locations. 2.20.5 tr'uture Land Use There is no planned change in land use for SWMU 50. Industrial use of the site in expected to continue for the foreseeable future. 2.20.6 Corrective Measures No COCs were identified at the Building 613 dran location. At Building 619, no COCs were identified in surface soil, and metals were identified as COCs in subsurface soil. At Building 619, metals were detected onty slightly above the corresponding CAO in one subsurface sample. Therefore, the corrective measures implemented at the site consist of ICs in the form of deed restrictions. The deed restrictions imposed are intended to prevent residential use or development of the site. The deed restictions have been incorporated in the property deed for this site, and are legally binding. Deed restrictions on the BRAC property are governed by the associated environmental covenants, conditions, and restrictions (CCRs). 2.20.7 Site Visit and Visual Inspection A visual site inspection was conducted at SWMU 50 (frgures 24 alold 25) was conducted on March 11,2008. There are no indication of past excavation or disturbance of the site. The deed restrictions implemented as the corrective measure for this site remain protective. The site is currently zoned by Tooele City for Industrial Use. No residential use or development of the site has occurred, nor is it planned. 2.21 SWMU 51 - Alodine Drvine Beds 2.21.1 Site Background SWMU 51 is located on the BRAC parcel in the forrrer TEAD industrial area. It consists of concrete pads located on an open lot south of the fonner Consolidated Maintenance Facility. Each of the pads is approximately 20 feet square, with bermed edges. SWMU 51 was reportedly used for drying and dewatering chromic acid and alodine wastes. It has also been reported, that the pads may have also been used to drain and flush radiator and engine fluids. 2.21.2 Site Investigations 36 Previous investigations at this site consisted of the collection of surface and subsurface soil samples. Metals and SVOCs were identified as COPCs in both surface and subsurface soil. 2.21.3 Site Risk The human health RA identified elevated cancer risks and HIs for onsite adult and child residents. No elevated cancer risks or HIs were identified for actual current and future industrial workers. All projected blood lead concentrations are less than the CDC target of 10 pgldl,. The site wide ecological RA classified SWMU 51 as presenting a moderate but not unacceptable ecological risk. 2.21.4 Current Land Use The current land use of SWMU 51 is industrial. The former TEAD industrial area, excessed under BRAC 93 is being redeveloped and a commercial industrial park. 2.21.5 Future Land Use There is no planned change in land use for SWMU 49. Redevelopment of the area as an industrial park will continue for the foreseeable future. 2.21.6 Corrective Measures One SVOC was identified as a COC in surface soil. It was detected at a concentration only slightly above its CAO and on one sa:rrple location only. The EPC for this contaminant is below it CAO. No COC were idelrtified in subsurface soil. Therefore, the corrective measures implemented at the site consist of ICs in the form of deed restrictions. The deed restrictions imposed are intended to prevent residential use or development of the site. The deed restrictions have been incorporated in the property deed for this site, and are legally binding. Deed restrictions on the BRAC property are governed by the associated environmental covenants, conditions, and restrictions (CCRs). 2.21.7 Site Visit and Visual Inspection A visual site inspection was conducted at SWMU 51 (figure 26) was conducted on March 11, 2008. The site as well as the surrounding area remain undeveloped. Vegetation on the site appears to be healthy and shows no sign of stress. There are no indication of past excavation or disturbance of the site. The deed restrictions implemented as the corrective measure for this site remain protective. The site is currently zoned by Tooele City for Industrial Use. No residential use or development of the site has occurred, nor is it planned. 37 2.22 SWMU 52b - Disposal Trenches 2.22.1 Site Background SWMU 52b is located on the BRAC parcel in the former TEAD administration area. The disposal trench site consists of a long mounded trench 150 by 40 feet, and several of smaller mounds. Pieces of construction rubble and debris are present at the surface and buried throughout the mounded area. The RFI field investigation confirmed that the trenches were used to dispose of rubble (construction debris). 2.22.2 Site Investigations Previous investigations at this site consisted of the collection of subsurface soil samples. Metals were detected in subsurface soils and identified as COPCs. 2.22.3 Site Risk The human health RA for SWMU 52b identifred elevated cancer risks and HIs for realistic onsite adult and child residents. No elevated cancer risks or HIs were identified for future construction workers. In addition, risks and hazards were not calculated for industrial workers, as these rece,ptors are exposed to surface soil only. 2.22.4 Current Land Use SWMU 52b is located on a portion of the BRAC parcel which has been designated for future residential development. The property currently remains undeveloped open land. 2.22.5 tr'uture Land Use Although the property has been designated for future residential development, there are no current plans to develop it as such. 2.22.6 Corrective Measures No COCs were identified in subsurface soil at SWMU 52b. Risks for future adult and child residents, the realistic future receptors are based on exposure to subsurface soil. The elevated HIs result forn elevated metals found between 10 and 11.5 feet below ground surface. Therefore, the corrective measures implemented at the site consist of ICs in the form of deed restrictions. The deed restrictions imposed are intended to prevent residential use or development of the site, as well as the excavation of subsurface soil. The deed restrictions have been incorporated in the property deed for this site, and are legally binding. Deed restrictions on the BRAC property are governed by the associated environmental covenants, conditions, and restrictions (CCRs). 2.22.7 Site Visit and Visual Inspection A visual site inspection was conducted at SWMU 52b (figure 27) on March 77,2008. The site is located on property excessed under the BRAC 93 action. The site remains undisturbed. Vegetation at the site appears healthy. 2.23 SWMU 54 - Sandblast Areas (Bldgs 611 and 637) 2.23.1, Site Background SWMU 54 is located on the BRAC parcel in the former TEAD industrial area. The SWMU consists of two sites where sandblast operations occurred. Three types of sandblast media were used at the site (i.e., steel grit, ground walnut shells, and glass beads). The spent medial had the consistency of fine dust and was collected in sealed hoppers located outside of each building. 2.23.2 Site Investigations Previous investigations conducted at SWMU included the collection of surface and subsurface soil samples. At Building 611, metals and SVOCs were identified as COPCs in surface soil, and metals were identified as COPCs in subsurface soil. At Building 637, metals and SVOCs were identified as COPCs in both surface and subsurface soil. 2.23.3 Site Risk The human health RA conducted at Building 611, identifred elevated cancer risks, HIs, and blood lead levels for onsite adult and child residents. In addition, elevated blood lead levels were identified for current and future industrial workers, as well as fufure construction workers. At Building 637, the human health RA identified elevated cancer risks and HIs for onsite adult and child residents. No elevated cancer risks or HIs were identified for current or future industrial workers, nor for future construction workers. All projected blood lead levels were below the CDC target of 10 pgldl. The site wide ecological RA classified SWMU 54 as presenting a low ecological risk. 39 2.23.4 Current Land Use The current land use of SWMU 54 is industrial. The SWMU is located on property being redeveloped as a commercial industrial park. 2.23.5 Future Land Use There is no planned change in land use for SWMU 54. It is expected that the site will continue to be developed as a commercial industrial park for the foreseeable futrue. 2.23.6 Corrective Measures Several metals were identified as COCs in surface soil at Building 61l. No COCs were identifred in subsurface soil. At Building 637, two SVOCs were identified as COCs in surface soil, though at concentrations only slightly above CAOs and at only two sample locations. No COCs were identified in subsurface soil. Therefore, the corrective measures implemented at the site consisted of the excavation and offsite disposal of contaminated soil at Building 61 1, along with ICs in the form of deed restictions at both Building 611 and Building 637. The deed restrictions imposed are intended to prevent residential use or development of the site. The deed restrictions have been incorporated in the property deed for this site, and are legally binding. Deed restrictions on the BRAC property axe governed by the associated environmental covenants, conditions, and restrictions (CCRs). In addition to corective measures implemented under RCRA, corrective actions under the State of Utah Leaking Underground Storage Tank (LUST) program have been completed or are planned at this site. At the time of the inspection all required corrective action under the LUST program had been completed with the exception of the 637 North tank location. Previous remediation of the site has resulting in a significant reduction in contamination, but additional work will be required. In the spring of 2006, a passive vent well will be installed at the site to address residual levels of contamination approximately 18'bgs. 2.23.7 Site Visit and Visual Inspection A visual site inspection was conducted at SWMU 54 (figures 28 and 29) was conducted on March 11, 2008. The site as well as the surrounding area remain undeveloped. The site as well as the surrounding area is covered with gravel and asphalt. There are no indication of recent excavation or disturbance of the site. The deed restrictions implemented as the corrective measnre for this site remain protective. The site is currenfly zond by Tooele City for Industrial Use. No residential use or development of the site has occurred, nor is it planned. 2.24 SWMU 56 - Gravel Pit Disposal Area 2.24.1 Site Background SWMU 56 is located on the BRAC parcel in the forner TEAD industrial area. The SWMU consists of an area where unknown materials were disposed of by burning, or possible where burned materials originating at other locations were buried in ffenches throughout the site. The exact origin of the burned materials, whether they were burned onsite or transferred from elsewhere is unknown. 2.24.2 Site Investigafions Previous investigations conducted at SWMU 56 included the collection of surface and subsurface soil samples. Lead and Thallium were identified as COPCs in surface soil and subsurface soil. . 2.24.3 Site Risk The human health RA conducted as part of the CMS identified elevated HIs, and blood lead levels for onsite adult and child residents. In addition, elevated blood lead levels were identified for current and future industrial workers, as well as future construction workers. The site wide ecological RA classified SWMU 56 as presenting a moderate ecological risk. 2.24.4 Current Land Use The current land use of SWMU 56 is industrial. The SWMU is located on property being redeveloped as a commercial industrial park. 2.24.5 Future Land Use There is no planned change in land use for SWMU 56. It is expected that the site will continue to be developed as a commercial industrial park for the foreseeable future. 2.24.6 Corrective Measures Lead and thallium were identified as COCs in surface soil and subsurface soil. The initial CMS for the site recommended excavation and offsite disposal of contaminated soil in order to eliminate the risk to all receptor groups allowing the site to be utilized as unrestricted use. Corrective measures were initiated at the site, and during that time, it was determined that it 4T would be impracticable to reach clean closure on the site. Additional site chancterization of the site was completed and a revised corrective measures study completed on the site to deterrnine the volume of soil which would need to be removed in order to reach industrial cleanup levels. In the revised CMS it was detennined that cleanup of the site should be to industrial levels, as the site is located within an area which had previously been restricted to industrial use. In December 2007 conective measures were completed on the site which included the additional removing of contaminated soil with concentrations of lead exceeding industrial levels, along with the application of deed restictions prohibiting future residential use or development of the site. 2.24.7 Site Visit and Visual Inspection A visual site inspection was conducted at SWMU 56 was conducted on March 11, 2008. The site as well as the surrounding area remain undeveloped. There are no indication of recent excavation or disturbance of the site, with the exception of the recent work done as part of the implemented corrective measures. The deed restrictions implemented as part of the corrective measure for this site remain protective. The site is currently zoned by Tooele City for Industrial Use. No residential use or development of the site has occurred, nor is it planned. 3.0 CONCLUSIONS The following conclusions support a determination that the corrective measures implemented at the SWMUs addressed by this inspection report are protective of human health and the environment, and that the restrictions and controls placed on sites are functioning as intended. Covenants, Conditions, and Restrictions placed on sites within the boundaries of the Utah Industrial Depot have been properly implemented and are functioning effectively. All actions undertaken by the Utah Industrial Depot that may affect any of the sites have been coordinated with the Army prior to implementation. Land use controls placed on sites located on the active portion of the installation remain effective in preventing residential development of the sites. Land use controls are documented and maintained in the installations Environmental Management Systern (EMS). Access confrols have been effective in preventing the trespassing of unauthorized personnel at the site. No known instance of trespassing by unauthorized personnel has been documented to date. No indicators of potential corrective measures failure were noted during this review. Costs and maintenance activities have been consistent with estimates developed during remedy selection. 42 . No additional infonnation has been identified that would call into question the protectiveness of the implemented corrective measures. 43 FIGURES \n$ aCBHo . t- { f.cBooJ)Bat)oa()ohA)- { tro F{ C)ooFa\ tr { o$- {)oo of itr r $# _ ;f i * 3*Nlo ?= E fr I i \IaI ff i f f i !d t r k{ ff i t- - {f 3&ff i frd{ tG' 1( O *- t N\t \ 't , t1 \^ * . j ,t ' iIt,t't ! -F . .
