SECTIONONE project Information 1.2 APPLICABILITY This Health and Safety Plan(HASP) summarizes health and safety hazard information for activities conducted by URS Corporation(URS)for RadioShack Corporation(RadioShack). It is not intended to encompass the scope of work that individual contractors are engaged in, nor is it designed to supply non- URS employees with all the information they need to perform their jobs safely. URS employees must follow the provisions of this HASP during all site activities. The HASP will be on site and readily available during site activities. All URS site personnel must read this HASP and sign the Safety Compliance Agreement(Appendix A)before being permitted site access. In addition, daily on-site health and safety tailgate meeting will be conducted. These daily meetings will be documented using the On-Site Health and Safety Tailgate Meeting Record Form in Appendix B. The elements and requirements of this HASP also apply to all URS subcontractor employees and URS- sponsored visitors.All URS subcontractors are responsible for their own work,their own health and safety, and for ensuring that they and their employees obey all applicable laws,regulations, and requirements for hazardous waste operations at the site. All URS subcontractor personnel and URS- sponsored visitors must read this HASP and sign the Safety Compliance Agreement(Appendix A)before being permitted site access. 1.3 SITE LOCATION AND DESCRIPTION The World Enterprises site is located east of Turnpike Road 500 to 1,200 feet south of the intersection of Downing Avenue and Turnpike Road in Stockton, California. The site operated as a debris disposal site (debris from demolished buildings, including wood, rubble, concrete, and other fill material) from 1970 through 1978. Currently the site contains a soil vapor extraction system and three groundwater wells. No structures are present. The property is open ground. Access to the property is a wood gate along Turnpike road, near the southwest corner of the property. On July 17, 2003, during an annual site inspection,the San Joaquin County Environmental Health Department(SJCEHD) staff measured methane gas concentrations up to 30,000 parts per million by volume (ppmV) (3 percent by volume)along the property boundary. As a result of this inspection, SJCEHD required Tandy Corporation(site owner, currently known as RadioShack)to assess whether the methane concentration along the property boundary was greater than 5 percent by volume, and if found to be greater than 5 percent by volume,to implement measures for controlling methane from leaving the site. RadioShack contracted with URS to assess the extent of methane at the World Enterprises site. Since 2004, URS has installed 10 gas-migration monitoring probes, 2 vapor extraction wells,and 3 groundwater monitoring wells at the World Enterprises site(Figure 2). In December 2005, a vapor extraction pilot test was conducted to evaluate the feasibility of installing a permanent landfill gas extraction system. During this test,vapor samples were collected from the two extraction wells and analyzed for volatile organic compounds(VOCs). Analytical results of these samples confirmed the presence of VOCs where the total VOC concentration in each of the vapor extraction wells was less than 5 ppmV. Based on these results,VOC constituents could be present in groundwater. To assess the presence or absence of VOC constituents in the groundwater, three groundwater monitoring wells (MW-1 through MW-3)were installed at the site on June 12, 2006.
