GENERAL DESCRIPTION OF PROJECT

The Delta Energy Center project is a 880 megawatt (MW), natural gas-fired, combined cycle electric generation facility located on an undeveloped 20 acre parcel at the Dow Chemical Company facility located generally north and west of the Delta Diablo Sanitation District treatment facility.

The project consists of a 3.3-mile, 230 kilovolt (kV) electric transmission line that interconnects to the electric transmission system at the existing Pacific Gas and Electric (PG&E) substation near the Pittsburg Power Plant. The line is above ground as it runs in front of USS POSCO Industries, and transitions to underground along 8th Street. A 0.8 mile underground 13.8 kV line supplies electricity to Dow Chemical. A 5.3 mile natural gas pipeline is in the existing Dow Chemical right-of-way along the Santa Fe Railroad and will connect to PG&E's Antioch natural gas terminal. Water for the cooling towers is secondary-treated wastewater from the Delta Diablo Sanitation District, which receives additional treatment on the project site to comply with the requirements of the Department of Health Services. A short water supply line runs from Delta Diablo to the project. Water for steam production and domestic uses is supplied by the Contra Costa Water District and transported in Dow Chemical's existing 20-inch pipeline. All plant discharges are sent back to the Delta Diablo Sanitation District for disposal in its existing discharge pipe. Approximately 200,000lb/hr of saturated steam is supplied to Dow Chemical in a 0.7 mile above ground insulated carbon steel pipeline.


Energy Commission Facility Certification Process

The California Energy Commission is the lead agency (for licensing thermal power plants 50 megawatts and larger) under the California Environmental Quality Act (CEQA) and has a certified regulatory program under CEQA. Under its certified program, the Energy Commission is exempt from having to prepare an environmental impact report. Its certified program, however, does require environmental analysis of the project, including an analysis of alternatives and mitigation measures to minimize any significant adverse effect the project may have on the environment.
