Earthgrains (former) page 2 1717 S. Center St., Stockton. Recommendations were not included in this report. In order to understand your future plans for this site, all reports submitted to EHD are to have a `recommendation' section, as well as a `conclusion' (summary) section. These two sections provide EHD with your consultant's professional evaluation of both the site and the interpretation of the most recent phase of investigation and the recommendation section allows EHD a view into your long-range plans for investigation and/or remediation plans. It appears to EHD that the installation of one soil vapor extraction well and one air sparge well in and adjacent to the former UST area would indicate that you are planning to conduct remedial action field testing in preparation for submittal of the required Problem Assessment Report (PAR), yet no discussion of this possibility was included in the report. EHD will review evaluations and recommendations included in reports and will comment and/or approve requests that are included. Without requests, recommendations, or questions in the report, EHD is unaware of your plans and has no alternative but to direct the next phase and establish deadlines for their submittal and drill/installation dates. EHD strongly recommends that a schedule for the next phase of investigation be included in every report submitted to EHD. Responsible parties should confer prior to the report release and agree on dates for the continued site work. The dates selected are to be included in the report along with the conclusions and recommendations. EHD will evaluate, comment, and approve, as appropriate, on the contents of the report. You are hereby directed to submit a work plan to continue the investigative phase for this site and commence field-testing of at least two remedial _ alternatives for returning the beneficial water beneath this site to `pre- release' conditions. A work plan, any permit applications, and fees are due at EHD before July 31, 2002. Please incorporate MW-4 into your quarterly monitoring program. In addition, 1,2-DCA, EDB, lead, methanol, and ethanol analyses are required for at least two consecutive groundwater-sampling events. If these constituents are not detected above acceptable detection levels for two consecutive sampling events, the analysis for the non-detectable contaminant may be discontinued upon request.
