Document Title: PG&E Topock Compressor Station Environmental Investigation and Cleanup Project
Document Type: SIR - Supplemental EIR
Received: 1/12/2017

Document Description: Groundwater beneath and near the Topock Compressor Station (TCS) has been contaminated by chemicals associated with historical wastewater discharge from station operations related to compression of natural gas in areas known as Bat Cave Wash and East Ravine. The Groundwater Remediation Project, as analyzed and approved in the 2011 Groundwater FEIR and the 2013 Addendum to the EIR, involves manipulation of subsurface water flow to move a contaminated groundwater plume with Cr(VI) and other chemicals of potential concern, originating from past operations at the TCS, through a treatment zone.
