Sevier Power nears air permit for gas-fired project in Utah

The Utah Department of Environmental Quality is taking public comment until May 11 on a draft air permit for a 580-MW, gas-fired combined-cycle plant being pursued by Sevier Power Co.

In September 2011, Sevier Power submitted a notice to construct and operate this plant, located near Sigurd, Utah, which is an attainment area for all criteria pollutants. As proposed, the plant will consist of two natural gas-fired, combustion turbines (CT); two, natural gas duct-fired, heat recovery steam generators (HRSG); a natural gas-fired auxiliary boiler; diesel emergency generator; and other associated equipment. The CT/HRSG units are dry low-NOx units controlled with both selective catalytic reduction (SCR) and oxidation catalysts (oxy-cat). The auxiliary boiler will be equipped with ultra-low-NOx burners (ULNB) and flue gas recirculation (FGR).

Sevier Power had at first planned a 270-MW coal plant at this site, but shifted gears, fuels and plant size when it ran into entrenched environmental opposition. An April 11 report in the Salt Lake Tribune said local opponents still plan to fight the revised project. Bruce Taylor, the power company’s managing director, was quoted in the article as saying about demand for power from this plant: “We certainly think Utah’s a strong market, and all of the West is a strong market. We also think that it’s an environmentally conscious plant.”
