The Colorado Department of Public Health is taking comment until Dec. 23 on a draft air permit that would allow the U.S. Air Force at the Buckley Air Force Base to construct and operate ten reciprocating internal combustion engines, supplying power to ten electrical generators.
All of this equipment is fueled by Ultra Low Sulfur Diesel Fuel, or alternative fuels which meet the standards of ULSD fuel. Emission controls include Diesel Oxidation Catalyst and Selective Catalytic Reduction. These sources are to be located at building 494, to be constructed at Buckley Air Force Base, Arapahoe County. The generators are to be rated at 2,500 kW each. This is to be called the Mountainview Power Plant.
“This source is classified as a Synthetic Minor Source as the emissions of Oxides of Nitrogen (NOx) and Volatile Organic Compounds (VOCs) would exceed Title V Operating Permit (TV) major source thresholds (100 tons per year) and emissions Carbon Monoxide (CO) would exceed Prevention of Significant Deterioration (PSD) major source thresholds (250 tons per year) if this source did not accept federally enforceable limits on emission control equipment and production limits,” said a department document. “These engines will have restrictions on hours of operation, fuel type, and emission control equipment requirements written into the permit that will restrict the hours of operation to control the NOx, VOC and CO emissions to below TV and PSD levels respectively.”
