`oe Meays is the LRA contact. Ruiz Grocery is currently in compli- ance with LRA directives as required by the underground storage tank regulations promulgated on December 2, 1991, by the State Water Resource Control Board. Ruiz Grocery received a commitment letter from the State Underground Storage Tank Cleanup Fund ( "SU- STCF" ) in July 1993. All work conducted pursuant to this bid will be funded by this SUSTCF. C. Scope of Work Groundwater Investigation - A letter from the LRA has requested Ruiz Grocery to further define the plume of the hydrocarbons in the groundwater. Quarterly sampling and testing of groundwater elevations, and reports of such information should be included in each bid (See Attachment 3) . Cleanup Methods - Because the building on the site is not sitting on an adequate foundation, soil excavation does not appear to be the most propitious remediation technique. In conversations with the LRA, vapor extraction appears to be the preferred remediation method. Consultants may bid on the above method, or propose another cleanup method that is considered to be more cost efficient. New technologies are encouraged, but a pilot test which proves the viability of whatever method is proposed must be conducted prior to implementation of the full scale program. All bids should include the following: ( 1) a proposal for fur- ther characterization of the contamination; (2 ) a proposal for quarterly groundwater monitoring; and ( 3) a remediation proposal. Ideally, bids will include an evaluation and comparison of sever- al feasible cleanup methods for the site, as well as a clear explanation for choosing the proposed method. Tasks - Bids shall include the projected total cost of cleanup as well as the unit costs involved in completing the following tasks: 1 . Preparation of a groundwater investigation work plan and detailed CAP to send to the LRA for review; 2. Obtaining the permits required from governmental agencies and modify, as necessary, the site safety plan pursuant to the PHS/EHD guidelines to execute the proposed work plan; 3. Implementation of a pilot study to test the viability of the proposed cleanup method; 4 . Purchase (or lease) of required equipment, and materials (minor items such as sampling equipment and materials can be lumped together under one category) , and construction of any structures, excavations, lined ponds, etc. ) ; 5 . Equipment operation and maintenance (per month) ; ' 1::\TRN\18437\D\003276.INV 2 76159-18437/LSG/08/18/93/1
