Under existing conditions, the project site is unoccupied and contains several soil <br /> stockpiles associated with the site's previous use as biomass energy facility, which has since been demolished. A <br /> Phase II subsurface investigation was conducted at the project site to investigate impacts of the potential release <br /> of hazardous materials that may have been handled on the project site as a result of previous on-site operations. <br /> The Phase II subsurface investigation included a geophysical survey, the advancement of 12 soil borings, and the <br /> collection of one shallow soil sample and one four-point composite soil sample. A total of 14 soil samples were <br /> analyzed for total petroleum hydrocarbons, volatile organic compounds, and metals. After analysis, the Phase II <br /> investigation determined that various metals are present within the subsurface at shallow depths; however, none <br /> of the detected metals exceed California Code of Regulations Title 22 criteria indicating that on-site soils would be <br /> considered a hazardous waste. If affected soil were to be moved off site, additional sampling may be required to <br /> confirm whether the soil meets receiving facility criteria, although such sampling would be required only to meet <br /> receiving facility criteria and the retaining of soil on site would not pose a risk to future occupants of the site. <br /> The Phase II investigation also found evidence of residual total petroleum hydrocarbons in soil beneath the <br /> project site; however, these detections are below the San Francisco Bay Regional Water Quality Board <br /> Enter project#s. —Initial Study 19 <br />
