Y Memorandum STATE OF CALIFGR111A + REGIONAL WATER QUALITY CONTROL BOARD • CENTRAL VALLEY REGION 3443 Routier Road Sacramento,California 9827 -3098 Phone: 916/361-5600 To: Regulatory Staff FROM: Gordon LBoggs . Undergro rid Tank Progra Coordinator DATE: 24 March 1987 SIGNATURE: SUBJECT: CONSULTANT REPORTS FOR ASSESSING GROUND WATER PROBLEMS AT SITES CONTAMINATE BY LEAKING UNDERGROUND STORAGE TANKS (LUSTS) In the course of our work we may review several proposals submitted by consultants on behalf of an underground tank owner to either initiate work to determine if a problem exists or, if one is found, the extent and 'appropriate remedial actions needed to alleviate the problem. Often we find that a report format has omitted essential information or the information has not been prepared in a manner that allows the local implementing agency (LLA) or us to review the proposal expeditiously. Such delays are neither cost effective for us or the tank owner. The problem is not necessarily one of the consultants' but a collective result of us all trying to accomplish a monumental task of permitting and cleaning up sites in a constricted time schedule. Our process should be one which would help minimize downtime for the tank owner. To facilitate and streamline our operations for Drovidinq tank owners and their consultants with our requirements for determininq the" stgnificance of a tante system leak, a consistent reporting procedure is indicated. %Phen ground water has been shown to be contarninated as a result of a tank leak, it would seern that three (3) reports should be sufficient to describe the problem and suggest remedial actions that would mitigate or eliminate the problem: 1. A Preliminary Report_ to assess the site and problem with suggessted boreholes and monitor wells needed to determine site status; 2. A problern ern &c- nt RePpj to describe the lateral and vertical extent of a problem anr1 propose mitigative or remedial actions to clean up a site. and; 3. The Final Remedial Pian acceptable to the regulatory agencies and tank owner for implementation on a time schedule. This consistent :approach should help reduce costs to the tank owner by reducing the nurober of int(�racti{nns with the regulatory agencies for interpretations an�7 guie,,arse and sampling itfr�jtions needed Dy the ccnsuitant to complete their work.
