SECTION 1.0 INTRODUCTION A: Proiect Overview The overall scope of work on this project site is to remove and dispose of the soil contaminated with lead paint residue located around the sandblasted piping at the Las Vinas Dehydrator Station. B: Site Description The Las Vinas Dehydrator Station houses equipment and materials for removing moisture and particulates from, and adding odorant to,natural gas in PG&E's transmission system. The facility occupies a ''/z acre site,which is owned by PG&E. The dehydrator station is unstaffed and has been in operation since 1942. Buildings, structures and equipment located at the Las Vinas station are identified on the attached facility layout map. The station yard has a gravel surface. The yard contains buried and aboveground high-pressure natural gas piping and equipment. A 6-foot high, chain-link fence topped with barbed wire surrounds the entire yard. There is two drive through gates to the facility. C: Work Plan 1. Mobilize on site. 2. Hold a pre-project safety meeting and layout the scope of work on site. 3. Utilizing a bobcat skid steer loader and personnel in Level "C"health and safety protection, with hand held tools, will dig up contaminated soil. The soil will then be placed into rolloff bins. 4. A composite sample from each bin will be taken for analytical testing. The samples will be tested for Total Lead Content. This information will be utilized to characterize each bin for the purposes of disposal. 5. After each rolloff bin has been loaded and sampled, it will be closed and will remain on site until it has been characterized for disposal and proper transportation arrangements have been made. 6. An area of 1250 sq. ft. (50'X25') and a depth of 6 inches will be removed around the sandblasted piping. Five confirmation samples will be collected from underneath the piping to ensure the removal of the sandblast residue is completed. 7. Additional material removal and confirmation testing will be performed in areas where testing shows impacted material remaining in the work areas. Additional soil will be removed, if necessary, until all impacted material is removed, or until concern for structural piping footing stability becomes a factor.
