Document Description
The project is the approval of a Clean-Up Plan by the DTSC for the Crown Coach Site under a CLRRA Agreement. DTSC is overseeing cleanup at this site pursuant to the regulatory authority granted under Chapter 6.8, Sec 25355.5 (a)(1)(C) of the California Health and Safety Code. The purpose of the Clean up action is to mitigate potential risk to human health and the environment by the Contaminants of Concern.
In 2004 a soil vapor extraction system was installed along the eastern boundary of the site with the Amtrak property. This system was later expanded to cover additional areas west of the boundary. This project involves the operation of a soil vapor extraction system that was previously installed and operated as a pilot test. Since 2011 the system has been shut down except for a 7-week period in 2013 to check for leaks. The compounds to be extracted are tetrachloroethene, trichloroethene, 1,2-dichloroethene and chloroform. There are 25 soil vapor extraction wells and 15 soil vapor monitoring probes and soil vapor sampling from these soil vapor monitoring probes indicates additional operation of the SVE system is required. It is estimated the SVE System will operate for approximately 2 additional years. The SVE system will require monitoring to comply with South Coast Air Quality Management District site specific permit requirements and granular activated carbon change.
Activities to be conducted:
- the operation of a previously installed soil vapor extraction system
- the periodic monitoring to determine clean-up progress and changing out of granular activated carbon of the SVE
- the decommissioning of the SVE once clean up goals have been obtained
