Abstract:  The construction of the West Virginia Ordnance Works (WVOW) was authorized on December 13, 1941, and construction began March 16, 1942. TNT production began October 21, 1942, and construction was completed September 10, 1943. The facility was designed with a production capacity of 720,000 pounds of TNT per day, operating 7 days per week, 3 shifts per day. The maximum attained production was 1,324,700 pounds of TNT in a 24-hour period during May 1945. TNT production was suspended at WVOW on August 15, 1945, following the end of World War II.

The U.S. Army manufactured sellite (sodium sulfite) at the Sellite Manufacturing Plant (Building 307A) from 1942 to 1945. Supporting facilities consisted of the soda ash storage building (Building 307B) and a sulfur facility (Building 307C). In addition, a box factory and storage facility (Building 814) was located at the site.

During the manufacturing of TNT at WVOW, sellite was used for the washing and purification of tri-oil as one of the final steps in producing TNT. Sellite was manufactured through the combination of soda ash and sulfur, which involved the use of sulfur melting pit and a sulfur furnace. The materials were combined in two batch tanks within the sellite plant, and the liquor produced was pumped to two sellite storage tanks located southeast of the plant.

During the initial operation of WVOW, sellite solution was transported from the storage tanks to the TNT Manufacturing Area by truck. However, because of the inefficiencies of this operation, a 4-inch-diameter steel line was installed in 1944 to supply sellite to the washer/flaker houses in the TNT Manufacturing Area, and the trucks were taken out of service.

Since the suspension of TNT manufacturing at WVOW in August of 1945, and the declaration of the WVOW site as surplus in December of 1945, the Former Sellite Manufacturing Area has had several uses. The site was initially used by the Mason Furniture Company (MFC) for the manufacturing of furniture from 1948 through the mid-1970s, operating out of Building 814. The Former Sellite Manufacturing Area property was most recently leased from the private landowner by the West Virginia Mulch Company for the manufacturing of mulch. Site activities included the receipt of raw materials, manufacture and storage of mulch, packaging of mulch, and the loading of tractor-trailers for transport of packaged mulch. These operations ceased in 1996, and the entire property is now vacant. In 1999, the EPA Remedial Project Manager (RPM) conducted a walkthrough inspection of the site and discovered approximately thirty-two 55-gallon drums of unknown material at various locations around the site. The private property owner had no knowledge concerning most of the drums. The RPM contacted EPA's removal program, and a removal action was performed. Thirty-two drums and a small quantity of contaminated soil were removed and disposed of by EPA.
Remedy:  No-Action Alternative - No remedial action alternatives were developed for the Site. The No-Action Alternative is the preferred alternative because no remedial action is required to protect human health or the environment from chemicals in the soil and groundwater at OU-11. The risk of human health and the environment presented by OU-11 in its current state is within acceptable levels. As presented here, the No-Action Alternative consists of monitoring of site groundwater annually for a period of 5 years. After groundwater monitoring is completed, a review will be conducted to evaluate the trend of the concentrations for bis(2-ethylhexyl)phthalate and lead to assure that they remain within an acceptable range. If so, the approximate area bounded by Wadsworth Road to the north, the TNT Manufacturing Area to the east, the McClintic Wildlife Area Boundary to the south, and the South Acids Area to the west will be proposed for removal from the National Priorities List (NPL).

Estimated Annual O&M Cost: $110,000
