During the third quarter Board staff concurred with SECOR's request to list <br /> monitoring well TS/M-2 as an "A"zone well instead of a"B"zone well as it had previously been <br /> listed. The FS provides a summary of previous field investigations, discusses the dual-phase <br /> extraction feasibility test, aquifer testing, ISO-GEN feasibility test, and ozone sparge feasibility <br /> test, and recommends submitting a corrective action plan. The ISO-GEN feasibility test was <br /> halted in July due to safety concerns regarding the integrity of the system's wiring. The post <br /> ozone injection test monitoring and sampling was not completed at the time of the FS submittal. <br /> California Environmental Protection Agency <br /> Co Recycled Paper <br /> The energy challenge facing California is real.
