SWMU 10 - Hazardous Waste Container Storage Building 154Y

SWMU 10 was located in Building 154Y as a greater-than-90-day waste storage bunker. Building 154Y consists of a concrete bunker covered with soil on all sides except the entrance.

According to the 1989 RCRA Facility Assessment (RFA), the floor of the bunker was treated with a waterproof epoxy coating and air vents extend through the roof of the bunker. The bunker began operating as a waste storage area in August 1981. Wastes managed included both characteristic (e.g., D001, D002, and D003) and listed hazardous waste (e.g., F001, F002, F003, and F005). At the time of the RFA, the bunker was operating under an interim status and a drainage ditch extended across the front of the bunker.

During a RCRA Compliance Evaluation Inspection conducted in June 1986, the majority of drums at the SWMU were either badly corroded or bulging. The contents of some of the drums had leaked on or were spilled on the ground. In addition, inspection reports indicated the drums inside the unit were in unsatisfactory condition during April and May 1987 inspections. However, during the RFA in 1989, no evidence of a release was observed either inside or outside the unit. SWMU 10 was managed under RCRA, therefore, no further action (NFA) was recommended.

 

SWMU 11 - Hazardous Waste Container Storage Building 163Y

SWMU 11 is located in Building 163Y and is a greater than 90 day waste storage bunker. SWMU 11 consists of a concrete bunker covered with soil on all sides except the entrance.

According to the RCRA Facility Assessment (RFA) in 1989, the floor of the bunker was treated with a waterproof epoxy coating and was sloped to drain into troughs. Air vents extend through the roof of the bunker. The front of the bunker previously had a railroad spur extending to the entrance of the unit. At the time of the RFA, a drainage ditch extended across the front of the bunker. The bunker began operating as a waste storage area in August 1981. Wastes managed at SWMU 11 include listed hazardous waste and large quantities of unknown waste. Polychlorinated biphenyls (PCBs), mercuric nitrate, and trichloroethene are known to have been stored at this unit. Designated areas within the interior of the bunker were used for storing alkali, acid, flammable, and other regulated material waste types. Twelve drums, all located on wooden pallets, were observed inside the building. Absorbent material emitting an organic odor was observed outside the bunker entrance in 1989; however, no staining was observed on soil surrounding the unit. SWMU 11 is managed under RCRA, therefore, requires no further action (NFA).

 

SWMU 12 - PCB Storage Building 198

SWMU 12 is a warehouse located in Building 198. Warehousing operations at Building 198 began in March 1976. The warehouse stored Kepone until the fall of 1978. During the RCRA Facility Assessment (RFA) in 1989, the building was storing PCB transformers and PCB oil. At the time of the RFA, this fully enclosed, locked building contained four 55-gallon barrels and three transformers situated on wooden pallets. The floor of the building is concrete treated with epoxy and no environmental releases were evident. SWMU 12 is regulated under the Toxic Substance Control Act (TSCA) and requires no further action (NFA).

 

SWMU 18 - Old Storage Yard #2

SWMU 18 is located south of Building 154Y and consists of an asphalt pad measuring approximately 100 by 400 feet. The area is used to store scrap metal and various types of metal equipment. Two old metal tanks with holding capacities of more than 1,000 gallons were observed during the 1989 RCRA Facility Assessment (RFA). The source of the tanks is not known but it appeared that they could have been boilers removed from a ship. It is not known when waste storage operations began at this unit. No releases were evident during the RFA.

This SWMU was determined to require no further action (NFA) due to the low potential for releases to surrounding environmental media.

 

SWMU 19- Old Storage Yard #3

SWMU 19 is located adjacent to Site 15 located at Building 271. This SWMU consisted of a fenced concrete pad which appeared to be the foundation of a building previously located at the site. The RCRA Facility Assessment (RFA) identified the area to measure approximately 40 feet by 500 feet. The pad is partially surrounded by a concrete berm less than 6 inches high. In the center of the pad is a small metal building measuring approximately 20 feet by 40 feet. The area was used to store scrap metal, obsolete equipment, and piping. It is not known when waste storage operations began at this unit. No releases were evident during the RFA. The RFA recommended site management practices be implemented at this SWMU. The SJCA Partnering Team site visit in November 2002 did not identify concerns with the storage yard and a consensus for no further action (NFA) was reached.

 

SWMU 21 - Hazardous Waste Accumulation Areas (SIMA#2)

SWMU 21 is located east of Building 47 and consists of a concrete pad measuring approximately 20 feet by 40 feet. The pad is surrounded by a concrete berm less than 6 inches high and sand bags. The area is enclosed by an 8-foot high chain-link fence and a locking gate. It is not known when this SWMU began operating. The RCRA Facility Assessment (RFA) conducted in 1989, stated that SWMU 21 received waste from Site 14. Waste stored at this SWMU include old batteries, waste lacquer thinner, lube, and oils. At the time of the RFA, there were approximately 13 batteries and two 55-gallon drums of waste lube oil located in the building. Waste material was stored at this SWMU before being transported to a RCRA interim status storage facility.

The RFA recommended no further action (NFA) for this SWMU. A SJCA Partnering Team site visit in November 2002 did not identify concerns with the SWMU and consensus for NFA was reached. The Navy submitted a closure notification letter to the Virginia Department of Environmental Quality (VDEQ) for SWMU 21.

 

SWMU 22 - Repair Shop satellite storage area Northeast of Building 40

SWMU 22 was a repair shop satellite area located northeast of Building 40. The SWMU is an outdoor concrete pad approximately 15 feet by 35 feet and is surrounded by sand bags on two sides and a concrete curb on the other two sides. The RCRA Facility Assessment (RFA) conducted in 1989 indicated that the pad was used in the past for the storage of hazardous waste for a period less than 90 days. According to the facility and the RFA, this SWMU began storing waste as early as 1985 and operated for approximately two years. In 1989 the unit was inactive and no waste was observed. Oily stains were noted on the concrete pad, but no soil staining was evident. The RFA recommended no further action (NFA) for this SWMU. A SJCA Partnering Team site visit in November 2002 did not identify concerns and consensus for no further action (NFA) was reached. The Navy submitted a closure notification letter to the Virginia Department of Environmental Quality (VDEQ) for SWMU 22.

 

SWMU 26 - Scrap Metal Storage in Railroad Cars Near Building 176

SWMU 26 consisted of four open-topped railroad storage cars containing scrap metal. The cars were located on an active railroad spur near Building 176. It is not known when waste storage in the railroad cars began. The RCRA Facility Assessment (RFA) conducted in 1989, reported that the types of waste included stainless steel scrap metal destined for Defense Reutilization and Marketing Office (DRMO). No environmental releases from this unit were evident. SWMU 26 is managed under RCRA and therefore, requires no further action (NFA).

 

SWMU 29 - Dumpsters (throughout the Facility)

SWMU 29 consists of dumpsters located throughout the SJCA facility. Certain dumpsters have closed tops. The RCRA Facility Assessment (RFA) conducted in 1989, reported that each dumpster is emptied on a regular schedule by a contractor for offsite disposal. According to the RFA, wastes handled in these dumpsters include burnable waste (e.g., refuse), salvageable waste (e.g., metal), non-burnable, non-salvageable waste (e.g., sand), and asbestos waste. No release to the environment were observed during the 1989 RCRA Facility Investigation (RFI) other than the dumpster identified at IR Site 7 (formerly SWMU 17). SWMU 29 is managed under RCRA and therefore, no further action (NFA) is required.

 

SWMU 32 - Overland Drainage Ditches

SWMU 32 consists of overland drainage ditches located throughout the SJCA facility. A series of overland drainage ditches were used to transport process wastewater and runoff from process areas to receiving waters. The 1989 RCRA Facility Assessment (RFA) indicated that process waste was collected and managed at waste generation points and was no longer transported via the ditches. Ditches in the vicinity of Site 4 were inspected during the 1989 RFA and there was no evidence of waste transport in these ditches and no evidence of environmental releases.

SWMU 32 was determined to require no further action (NFA). Drainage ditches associated with individual sites, AOCs, or SWMUs will be investigated on a site-specific basis. Site-specific investigations will identify the exact boundaries of the drainage ditch and samples will be collected at all locations where there is either visible evidence of release or suspicion that past releases may have occurred.

 

SWMU 33- Sewer Drainage System

SWMU 33 consists of the underground sewer drainage system used for both sanitary sewage and storm water runoff. The 1989 RCRA Facility Assessment (RFA) indicated that past waste management practices were to wash unspecified waste into floor drains. Ultimately, this waste would enter either the sanitary or storm water sewer system. Waste was generated from fuze drill-out operations, ammunition breakdown operations, steam-out operations, degreasing operations, and boiler plant operations.

During the RFA, it was noted that the oil/water separator (Site 9), which collects rinsate from the wash pad at Building 249 (also part of Site 9), is tied to the sanitary sewer. It was also noted that unspecified spilled liquids in operational areas may enter the drain system.

This SWMU requires no further action (NFA). The sewer drainage system associated with individual sites, AOCs, or SWMUs will be investigated on a site-specific basis. Site-specific investigations will include evaluating the integrity of the subsurface system and may include soil sampling to determine if hazardous constituents have been released.

 

SWMU 34 - Operational Waste Accumulation Areas

SWMU 34 consists of various waste accumulation areas located throughout SJCA. The areas are located in enclosed buildings with concrete floors. According to the 1989 RCRA Facility Assessment (RFA), a typical operational waste accumulation area is a "two-day" storage area located within a portion of the building designated as the waste accumulation area and identified as a painted floor area. Typical waste accumulation areas contained a single, closed, 55-gallon drum and a closed, 5-gallon can.

The waste managed at each unit is specific to the operation being conducted in each building. Wastes are expected to include various waste oils and solvents. No environmental releases were observed during the RFA.

SWMU 34 is managed under RCRA, therefore no further action (NFA) is required.
