Topock Compressor Station
PG&E's Topock Compressor Station is located in eastern San Bernardino County, about 15 miles southeast of Needles, California just west of the Colorado River. Since 1951, the Station has compressed natural gas for transportation through pipelines to PG&E’s service area in central and northern California.
PG&E is committed to addressing environmental issues resulting from our historical operations at Topock. As part of this commitment, PG&E has been working under the oversight of the California Department of Toxic Substances Control (DTSC) and the U.S. Department of the Interior (DOI), and in coordination with local Native American tribal governments, to investigate and clean up hexavalent chromium in groundwater and soil. Both DTSC and DOI have stated that there is no current risk of adverse health effects due to groundwater at the Topock site or potential for exposure.
Groundwater impacts have been defined based on detailed investigation sampling, and monitoring program with data collected from 1997 to the present. Those impacts are localized and do not extend north of National Trails Highway or across the Colorado River. The local communities of Golden Shores and Needles are not impacted by PG&E’s chromium contamination. Both DTSC and DOI have stated that there is no current risk of adverse health effects due to groundwater at the Topock site or potential for exposure.

Latest Project Update
PG&E is in the process of developing a plan to clean up groundwater at the Topock site. This plan, called the Remedy Design, is in the intermediate stage, known as the 60% Design. On April 5, 2013, the 60% Design was submitted to the oversight agencies. It will be reviewed by the agencies, tribes and interested stakeholders and their feedback will help refine the cleanup design. Following the 60% Design, the plan will enter the pre-final stage, known as the 90% Design. Construction of the remedy components is scheduled to begin in late 2014.
