PG&E Former San Luis Obispo - 1 Manufactured Gas Plant Remedial Action Plan

Description

DTSC has approved a RAP for the PG&E Former San Luis Obispo-1 Manufactured Gas Plant Site pursuant to regulatory authority granted under Chapter 6.8, Division 20, sections 25323.1 and 25356.1, H&SC. The Draft RAP, dated March 25, 2015, was prepared by Terra Pacific Group for PG&E and is incorporated as reference herin. The purpose of the project is to address impacts to soil and groundwater from previous operations on Site. Remedial activities will involve excavation and disposal of approximately 20,000 tons of contaminated soil at an off-site permitted facility. The soil is impacted by polycyclic aromatic hydrocarbons, arsenic, lead, and petroleum hydrocarbons. Additionally, approximately the same amount of clean backfill will be imported from a quarry located in Santa Margartia, CA, approximately 14 mi north of the site. The imported fill will be tested for contaminants in accordance with DTSCs October 2001 Imported Advisory on Clean Fill Material.
