3 Installed three dual completion vapor extraction/air sparge wells (VEAS-1 through VERS-3) on-site for the purposes of conducting pilot study activities The two foot air sparge point was installed to a depth of approximately 65 feet bgs, with the corresponding vapor extraction well set at approximately 50 feet bgs, and screened from approximately 15 to 50 feet bgs in VEAS-1 and VEAS-3 VEAS-2 was screened from approximately 10 to 50 feet bgs The scope of work included preparation of a Community Health and Safety Plan, site reconnaissance, permitting, well drilling, organic vapor monitoring, soil sampling (for lithologic logging, analytical testing and waste characterization purposes), well surveying, groundwater gauging and sampling, analytical chemistry, data interpretation, and report preparation Each part is described below 5 1 Community Health and Safety Plan ATC has established a Safety and Health Program (SHP) to ensure the personal health and safety of all ATC employees The SHP defines safety practices and procedures to be instituted in all ATC work ' places, as applicable The program meets, and often exceeds, the requirements promulgated by the Occupational Safety and Health Act (OSHA) As part of the SHP, all ATC personnel are appropriately ' trained and under a Medical Surveillance Program in accordance with OSHA 40 CFR 1910 120 ATC's primary mechanism to ensure employee, environmental, and public safety at the project site was ' the Community Health and Safety Plan (CHASP) ATC prepared, approved and implemented a CHASP for this project All individuals working under the purview of ATC were required to read and sign the CHASP to acknowledge their understanding of the information contained in it The CHASP was site- specific and task-specific, describing hazardous conditions that may be encountered and prescribing the necessary safety protocols to protect employees from these hazards The CHASP was reviewed by the ' project management team and then reviewed/approved for field use by the Site Safety and Health Officer The CHASP was implemented and enforced on site by the assigned Site Safety and Health Officer ATC prepared a comprehensive CHASP based on the scope of work and the potential hazards described in the ' ATC work plan dated December 21, 2001 The CHASP identified the following roles and responsibilities of key site personnel, hazard analysis for all chemical, physical, and physiochemical hazards anticipated, a personnel protection plan, site safety procedures for specific site operations, (e g, drilling, etc ), a decontamination plan, and an emergency ' response/contingency plan The CHASP specifies levels of protection for site personnel on a task-specific basis As with any project of this magnitude, there are inevitable encounters with a variety of physical hazards ranging from simple housekeeping to temperature extremes ATC provided continual evaluation ' of potentially hazardous conditions, and as the project progressed additional safety protocols to protect site personnel were implemented as needed EZ 100966ASARrpt ATC Associates Inc ' \\S at)Diego1EZ Serve11009661Reports1100966SAR001 rpt ATC Project No 43 25827 0026 ' 6
