Document Description
Approval of a Draft Removal Action Workplan (hereafter Workplan) by the Department of Toxic Substances Control (DTSC) pursuant to Health and Safety Code, Chapter 6.8 as submitted on March 23, 2012 by the Terra Pacific Group on behalf of Pacific Gas and Electric Company. The Workplan focuses on excavation and removal of total petroleum hydrocarbon, polycyclic aromatic hydrocarbon (PAH) and metals (lead and arsenic) contaminated soils near an underground storage tank (UST) at the northernmost parcel at the site adjacent to a railroad right-of-way. Lead and arsenic occur in shallow soil (<feet deep) and are associated with the former MGP operations and not the contents of the UST. PAH compounds are a minor component of the TPH (oil) stored in the UST. Total petroleum hydrocarbons (TPH) at concentrations of up to 70,000 mg/kg were detected at depths of up to 35 feet below ground surface in site soils. Only low concentrations of benzene and ethylbenzene were detected. The purpose of the project is to reduce the potential migration of the impacts to groundwater, thereby reducing or eliminating future land use restrictions and groundwater monitoring requirements associated with the UST impact. This will be achieved by removing the UST and vicinity impacted soils that exceed action levels established for protection of groundwater.
