Five coke-burning power plants proposed for Contra Costa County would pose a negligible risk of cancer, according to a study prepared for the Bay Area Air Quality Management District. The study by HDR Tech-Serv Inc. of Santa Barbara “gives us a clean bill of health,” said Steve Wilburn, project manager for GWF Power Systems Co. of Irvine, which hopes to have the plants in operation by 1988. The plants, to be built in Antioch, Pittsburg and West Pittsburg, would provide electricity for 90,000 homes.
