During plant operations, most of the manufacturing and assembling operations were conducted in the Middle Sector buildings. Current site features include vacant buildings on the Middle and North sectors which range from 200 to '800 feet in width, an oil pump house, abandoned storage tanks, a concrete dike and a paved lot. entire Th e facility extends along Sharpsville Roa nearlr dmilee fo a yr on pag .n fo o (Se 0 ep 1 ema layousite.e th )f to site borderes Th Citei e nortSharpsvillee f yth o th y hb n deaso e Sharpsvilly tth b n ;o e Avenud ean residential homes; on the south by Winner International and the City of Sharon; and on the west by ARMCO Steel Corporation.

In 1984, two major incidents occurred at the site which released PCBs and other chemicals into the environment. The first incident occurred when approximately 6,000 gallons of a mixture containing transformer oil petroleu,a m produc silicond tan e flui releases dwa d aftera malfunction in one of the facility's heat exchanger units. The heat exchanger malfunction caused the mixture to be released from Its underground storage tank into the surrounding soil and groundwater. Because this storage tank housed 1960sPCBe th A sn believe,i EP s tha soie ltth around the tank was already contaminated with PCBs. Therefore, the released liquid flowed through the soil,, absorbed PCB contamination, and collected in a pond near the plant drainage area, calle moate dth .pagn o (Se ep e10. ma A als)EP o believes that during this time, PCB- contaminated oil leaked into sewers at the site and drained into the Pine Run tributary of the Shenango River. The second release, in November, 1984, involved the facility's coal-crusher sump. Upon discoverin densga e drainagliquie th n di eplante areth f ,ao facility officials investigate source dth e thf o e materia discovered lan d that approximatel gallon4 y10 PCBf so s remainin sume d th pha n g i leaked and collected in the onsite moat. Although contamination from these two events was contained from spreading further, the moat, soils and groundwater at the site remained contaminated, : Site Investigation d Regulatorsan y Action, s In April 1985, after initial site investigations, the Pennsylvania Department of Environmental Protection (PADEP) [formerl Pennsylvanie yth a Departmen Environmentaf to l Resources] issued an Administrative Order to Westinghouse to investigate the sources and amount of PCB-oil and industrial solvent contamination at the site. Under the Administrative Order, Westinghouse conducte subsurfac e dstuda th f yo e condition site eth andt sa Augusn ,i t 1986, submitteo dt PADEP a report detailing the study and its findings. The 1986 study revealed that soils and groundwater at the site contained hazardous substances, including PCBs and other organic compounds. In November 1985, at the request of PADEP, EPA investigated the site and detected PCBs at thf o e fouo tw r locations where Westinghouse discharged plant water intShenange oth o River. This caused concern because the Shenango Valley Water Company, located downstream, uses the Shenango Rive its ra s water source. PCBs also were detecte riven di r sediments collected nea. r the site. As a result of these findings, EPA proposed the site for inclusion on the National Priorities List (NPL Jun)n i e 1988 anticipation .I thf neo site bein gNPLe listeth ,n d o PADE d Pan Westinghouse entered into a Consent Order and Agreement on September 21,1988. This order and agreement requires Westinghouse to conduct a remedial investigation and feasibility study at the site. The Westinghouse Sharon Site was formally included on the NPL in 1990. As part of the remedial investigation, samples were collected from several site monitoring wells during field work in 1992 and 1993. Sampling results from these wells indicated that PCS- contaminated oil was present in the groundwater beneath the site, The discovery of this contamination led to further investigations which revealed that an estimated 5,000 to 10,000 gallon oif slo contaminated with PCBs, dioxins, chlorinated solvent trichlorobenzend san e forme separatda e aqueous layer whic thf o efloatins groundwatehp wa to n go r beneat sitee h.th Becaus potentiae th f e thio r lsfo oi Shenangtravee o lt th o lt o Rive affecd r an Shenang e tth o Valley water supply A issue,EP Unilaterada l Administrative Orde Westinghouso rt Februarn ei y 1994.
