Abstract: The U.S. Department of Energy (DOE) prepared this Environmental Assessment (EA) to assess the environmental and human impacts that would result from DOE's participation in a cooperative agreement between DOE and Northwest Fuel Development, Incorporated for the construction and operation of an Integrated Power Generation System for Coal Mine Waste Methane Utilization. DOE's objective in participating in the agreement is to support demonstration of a technology that has the potential to reduce methane emissions from coal mines. Specifically, DOE seeks to provide partial funding ($600,000 or approximately 35% of the total project cost) to demonstrate the application of a system which would collect"gob gas"(waste methane from the mined out portion of an underground mine following extraction of the coa using 1ongwall mining), upgrade the gas by removing impurities (primarily water, carbon dioxide, and nitrogen), and use the fuel gas in a series of 18 modular gensets (reciprocating internal combustion engines driving electrical generators) to generate electricity for use at the mine. A portion of the gas which meets pipeline quality standards would sold to the local gas distribution company.
