Y -- REMEDIATION OF RESIDENTIAL SURFACE SOILS, DAYTON AND SILVER CITY, NEVADA SOL ZU1121 DUE 031497 POC Mary Ann Wright, Subcontract Manager, (202) 624-9537. Solicitations are requested for services to remediate a limited portion of the Carson River Mercury Site, a federal Superfund site in Lyon and Churchill Counties, Nevada. Funding for this project by the United States Environmental Protection Agency is in place. Proposals are due by 4:30 p.m., March 14, 1997. The contaminant of concern is mercury, which was imported to the area during the Comstock mining era in the late 1800s and was used to remove gold and silver from crushed ore. Mercury is still present in several residential areas built on or near former mill sites. The purpose of the project is to implement the EPA Record of Decision (March 1995) which calls for excavating and removing up to two feet of surface soils containing concentrations of total mercury in excess of 80 parts per million, in five residential areas in Dayton and Silver City, Nevada. The total surface area to be addressed is approximately 3.5 acres and the inplace volume of soils to be removed is about 4,500 cubic yards. The project requires excavation to depths of 0.5 to 2 feet, with transport of soils offsite to a permitted landfill or for reuse if allowable. Excavated areas shall be restored with clean backfill, rolled gravel parking surfaces, garden beds, or lawns. In one area a soil barrier wall will be required, consisting of either poured concrete or masonry block. The contract is anticipated to begin in early April, 1997, with substantial completion by August 15, 1997. This description of work is not intended to be all encompassing. A full description of all work to be performed is included in the detailed plans and specifications (design sets) available from the above stated address. The design set is expected to be available on or about February 10, 1997. Interested parties may obtain copies of the design sets upon payment of $100.00 in check or money order, payable in US funds drawn upon a US financial institution, to Ecology and Environment, Inc. for each complete set. Cash will not be accepted. Requests for the design set must be sent to the above address and must include the name of the person to receive the design set, the street address of that person and their telephone number. Design sets will be sent by overnight delivery. Attendance by prospective bidders at a pre-bid conference and sitewalk is mandatory. The tentative date for the pre-bid conference and sitewalk is Thursday, February 20, 1997 in Carson City Nevada, from 9AM to 3PM. Transportation to and from the site will be provided. The exact time and location will be included in the cover letter accompanying the design sets.

Prospective bidders are advised of the following (1) Areas to be remediated are on private property and site access is limited. (2) All requests for information must be in writing. (0029)
