ADEQ Issues Air Permit for Coal-Fired Electric PLant

They tried to build several in Texas but were stopped, so they came to Arkansas. Another in planning stage for Northeast Arkansas and Oklahoma. There are concerns the OK plant will drift over the Ozarks. Note there is no limit on CO2 emissions.

ADEQ ISSUES AIR PERMIT FOR COAL-FIRED ELECTRIC PLANT

The Arkansas Department of Environmental Quality (ADEQ) has approved a final air permit for construction and operation of a coal-fired electric power plant in Hempstead County. The permit, signed November 5, was issued to Southwest Electric Power Co. (SWEPCO), a unit of American Electric Power (AEP) for construction of the John W. Turk, Jr., generating plant near Fulton.

The permit application had been under review by the ADEQ for more than two years, and was the subject of two public hearings and two separate public comment periods totaling more than three months, during which hundreds of interested parties offered comments on the proposed permit.

“This is a complex and controversial permit application,” ADEQ Director Teresa Marks said. “It has undergone a lengthy review by technical and legal personnel to make sure the permit is protective of public health and the environment by conforming to all applicable air emission standards under state and federal laws.”

The main steam generating unit consists of one ultra-supercritical pulverized coal boiler fueled by low sulfur coal and natural gas which will power a single steam turbine designed for base load operation with a nominal net power output of 600 megawatts.

The permit contains emission limits for such pollutants as particulates, sulfur dioxide (SO2), volatile organic compounds (VOC), carbon monoxide (CO), nitrogen oxides (NOx), and mercury. There are no limits in the permit for carbon dioxide (CO2), which currently is not subject to emission limits under federal or state regulations.

However, the Turk plant design includes a 20-acre area for the inclusion of CO2 capture equipment, should future regulations impose CO2 emission limits.

“It is quite possible CO2 emission standards will be adopted at the federal level and in Arkansas as well in a few years,” Marks noted. “The ADEQ and the operators of all permitted coal-fired electric plants in the state--as well as a variety of other industrial and commercial operations with significant CO2 emissions--are aware of this possibility and are already considering options to address the issue of CO2 emissions as quickly as possible once standards are in place.”

Currently, Arkansas has six permitted coal-fired electric generating units; two near Redfield in Jefferson County, two near Batesville in Independence County, one near Gentry in Benton County, and one near Osceola in Mississippi County.
