EXTEND PERFORMANCE PERIOD OF EXISTING A/E CONTRACT #263-95-C-0252 It is the intent of the National Institutes of Health to extend the period of performance of the existing contract to Maxim Technologies, Inc. to allow for the operation of Phase 11A remediation action at the Bitterroot Valley Sanitary Landfill (BVSL) "Groundwater Monitoring" in Ravalli Count Montana. The existing contract (base and 4 option years) expires at the end of calendar year 2000. The need for the 11A action will require extension of that contract through the calendar year 2005 in the form of an additional five years. Due to the sensitive and highly complex nature of the project, it is in the best interests of the Government to maintain continuity of expertise through extension of this contract. Maxim Technologies, Inc. has been associated with the project since its inception and has amassed considerable knowledge of the site and its environs. Maxim is responsible for the design and construction of the Phase 11A pilot test facilities and full scale implementation facilities. Maxim developed a transient groundwater model which describes the transportation of contamination due to volatile organic compounds in the groundwater of the Bitterroot Valley Landfill.
