Back-Up Generator Facility and Associated Project Environmental Assessment Dyess Air Force Base, Texas.

摘要

Air Force bases have high energy demands and must maintain a consistent, safe energy system. In recognizing these requirements, the Air Force entered into Energy Savings Performance Contracts wherein an energy service company, like Siemens, finances and develops projects to provide consistent safe energy systems. Improving power and energy capabilities at government-owned facilities form the fundamental purpose behind Energy Savings Performance Contracts. The energy service company provides all the studies, designs, construction labor, materials, and equipment for the project. Cost savings generated over the life of the contract (e.g., 15 to 20 years) repay the investment of the energy service company. The purpose of the proposed action is to implement two energy security and conservation projects at Dyess AFB, Texas. Under this proposal, Dyess AFB would authorize Siemens to construct and operate a back-up power plant using up to five diesel-powered generators capable of producing a nominal 11.25 MW, and install three upgraded/replacement water-pump motors in the base's existing potable water distribution plant. Under this program, Dyess AFB could pay less for energy than currently because of real-time pricing (using current hourly rates vice fixed price rates) with new back-up generators; and water-pump motor replacements would enhance efficiency and conservation. Under the no-action alternative, the Air Force would not authorize Siemens to construct or operate energy security or conservation projects at the base. Water pump motors would not be replaced and/or upgraded. In addition, existing sub-standard water-pump motors would continue to be used. This EA analyzed the potential environmental consequences of the proposed action and no action alternative for air quality, hazardous materials and hazardous waste, soils and water, biological resources, and socioeconomics.
