LFR Levine-Fricke present in the sample collected from well MW-2 at a concentration of 26 micrograms per liter(µg/1), VOCs and SVOCs were not detected above laboratory reporting limits in groundwater samples. 3.0 SUMMARY OF REMOVAL ACTIONS Removal actions at the Site to date include activities conducted under the authority of the CIWMB Notice of Exemption(NOE) in accordance with Title 14, California Code of Regulations, Section 15308. A copy of the NOE is provided in Appendix F. The NOE covers the removal of abandoned vehicles, metal debris, scorched equipment, approximately 50,000 used motor oil filters, several used oil drums, and other activities associated with site preparation(e.g., electrical power supply and telecommunication lines). The Site is fenced with a lockable gate to prevent unauthorized entry. The objective of the pre-construction removal activities described above was to clear the project site of large debris and create sufficiently large staging areas for site management, trucks, decontamination areas, and installation of electrical and telephone communications equipment/lines. Sukut Construction Inc. (SCI)performed the pre-construction removal activities under the supervision of the CIWMB with the authority provided by the NOE. On March 17, 2003, before pre-construction removal field activities began, LFR and SCI personnel surveyed the Site with a representative of the CIWMB to assess the potential project impact on biological resources. An LFR biologist identified areas of concern to the SCI representative, including areas that should not be excavated or traveled on with heavy machinery or equipment. No live animals or evidence of active dens for endangered species were found near the areas of remediation activity. Based on the initial field survey, SCI was given the notice to proceed with pre-construction removal activities. A field activities site safety meeting was held on March 20, 2003, and included SCI staff, LFR staff, and CIWMB representatives. Large debris, including burned trailers, dilapidated structures, abandoned vehicles, and miscellaneous waste, was transported to an off-site metal scrap facility. The approximately 50,000 used motor oil filters, oil drums, and remaining oil in the abandoned vehicles were transported to licensed facilities by an SCI subcontractor. SCI followed industry standard dust control protocols and maintained a daily field log of activities. 4.0 SUMMARY OF SITE RISKS This section provides a summary of the extent of contamination at the Site based on the analytical data obtained during the preliminary RI/FS. This section also provides an overview of the chemicals of concern and potential migration and exposure pathways. Final_RAP_Tracy_9.18.03(final).doc Page 5
