The proposed action is construction, operation, and maintenance of an adequately sized and properly constructed Class II sanitary landfill expansion to support the continued operations at the Tonopah Test Range TTR facility. The landfill would be located adjacent to the north side of the existing solid waste facility, would have a designed fill rate of 500 cubic yards per month and could accept all non-hazardous solid and semi-solid wastes. The preferred design for the expansion is a two cell configuration with a total life expectancy of 30 years. Each cell would be constructed with sufficient space to allow a bulldozer or dump truck to maneuver and turn around. Additionally, three gas monitoring wells would be installed in conjunction to monitor gases released from decomposition of the waste. In determining the proposed site and action, a preliminary analysis of reasonable options for accomplishing the project was conducted. These options included a No-Action Alternative, two off-site waste disposal plans, and alternative designs. The analysis indicated that only one option, the proposed action, would meet operational, cost, and security requirements. Implementation of the proposed action and the alternative actions would have no significant impacts on land use air quality water resources safety hazardous materialshazardous waste solid waste biological resources cultural resources geology and soils and socioeconomics. The proposed expansion would be designed using adequate engineering controls to ensure that solid waste materials are properly stored and that the possibility of releases is minimized to an appropriate level of risk. Additionally, the proposed action would allow the TTR facility to operate at its current output and security parameters without significant modifications.
