Activities Planned for Next Quarter: As agreed to at the May 22, 1996 meeting, PG&E is combining the soil and groundwater into a single feasibility study. The draft schedule submitted to the agencies on June 6, 1996 includes several agency meetings to be conducted prior to submittal of the draft soil and groundwater feasibility study. These include meetings and/or conference calls to discuss and agree on: source areas, ARARs and screening technologies; screening of remedial action alternatives; and detailed evaluation of remedial action alternatives. On July 9, 1996, PG&E received a letter from DTSC regarding the proposed feasibility study approach clarifying that DTSC considers background or non-detect to be the starting point for evaluating technologies in the feasibility study. The letter also suggested that more information is needed to define soils to background levels. PG&E is preparing a response to this letter.
