                 WINSTON - THOMAS SEWAGE TREATMENT PLANT


The Winston-Thomas Treatment Plant, located on the southern edge of
Bloomington, is the city's former wastewater treatment facility. During the 
1960's and 1970's, PCB-contaminated effluent from the Westinghouse Plant at
Curry Pike was discharged to the Winston-Thomas Treatment Plant. Several 
areas of this 26 acre facility are contaminated with PCBs including a large 
tertiary treatment lagoon, two abandoned lagoons, sludge drying beds, 
trickling filter, and sludge digester tanks. Sludge sampling results indicated 
PCB concentrations to 4,000 parts per million. Levels of up to 22.1 parts per
billion were found in surface water runoff from the site.

The Winston-Thomas facility was closed in 1983. In 1986, an Interim Storage
Facility located adjacent to the Winston-Thomas Plant was approved and
subsequently constructed. Excavated materials from the other PCB-contaminated 
sites around Bloomington, along with the sediments from five area stream beds 
and excavated materials from Anderson Road, were transported to and stored in 
this facility. Westinghouse conducts monthly inspections and submits reports 
to EPA.

Westinghouse conducted other interim remedial measures beginning in November,
1990 that included:
       
  Decontaminating water in digester tanks.
  
  Removing and incinerating excavated capacitors from other Bloomington 
  PCB-contarninated sites.

The approximately 50,000 cubic yards of contaminated material await final
disposition at the site. About 9,400 tons of material are stored within the
Interim Storage Facility.
