EPA intends to extend Contract 68-C5-0036, "Field/Pilot Scale Evaluation of Biological Treatment Technologies for Superfund Cleanup", to allow completion of the following work assignments: WA 5 -- Phytoremediation Demonstration; WA 12 -- Demonstration of Enhanced In-Situ Bioremediation of Chlorinated Compounds; WA 14 -- Alternate Cover Assessment Project; WA 18 -- Demonstration of Ecomat Inc.'s System for Biological Denitrification and Removal of Carbon Tetrachloride from Groundwater; WA 19 -- Evaluation of Phytoremediation of Radionuclides at INEEL; WA 20 -- Demonstration of In-Situ Stabilization of Mercury Mine Waste; WA 21 -- Evaluation of Technology for Removal or Degradation of PCBs From contaminated Soil; WA 22 -- Demonstration of In-Situ Biodegradation of Chlorinated Solvents at the Fisherville Mill Site; WA 23 -- Evaluation of EquIS Environmental Data Management System; WA 24 -- Evaluation of Technologies/Processes for Remediation of MTBE Contaminated Groundwater. Each of these work assignments is either in some phase of the field work associated with the demonstrations or is in the data reduction and report preparation phase of the process. It is estimated that about 10,000 hour and an additional 12 months will be required to complete the work. Companies that feel they can provide the Government's requirements may submit qualification statements that explain how the technical work will be completed within the time schedules negotiated for each demonstration and without compromising the validity of the data generated during the demonstrations. Responses must be received no later than 15 days after publication of this notice. Posted 07/18/00 (W-SN475964). (0200)
