Margaret Lagorio [EH] From: Margaret Lagorio [EH] Sent: Monday,August 21, 2006 4:05 PM To: 'tmartin@kleinfelder.com' Cc: Laurie Cotulla [EH] Subject: 18880 Spreckles Rd., Manteca Tony, I shared your E-mail with my supervisor. We reviewed our files and discussed the situation. The Health and Safety code Section 101480 allows responsible parties and local officers to enter into remedial action oversight if the local officer has adequate staff and the technical expertise. In order to give proper notification to the Central Valley Regional Water Quality Control Board (CVRWQCB)and Department of Toxic Substances Control on a proposed agreement for local agency remedial action oversight, assessment of soil and/or groundwater must be completed. Most of the work plans that were approved by Enivironmental Health staff in 1997 had a statement that the work was for assessment purposes only and the work was subject to (CVRWQCB) review and approval. I previously gave you the areas/reports that had been provided certification by our agency. Some of the investigations you performed were for contaminants that our agency has no technical expertise on such as those involving metals, solvents, pesticides and herbicides, so we would not enter into an agreement for those issues. I contacted Ross Atkinson at the CVRWQCB about these issues and he said oversight would be provided by the SLIC unit of CVRWQCB. I have left a message for Duncan Austin, the supervisor of the SLIC unit, to discuss their interest in these contaminants. You can submit a Site plan that identifies the different locations investigated with report numbers placed on the areas identified and any written correspondence from EHD that indicated we would provide oversight on those locations (that are locations that have not been furnished closure letters)for our consideration.
