Muskogee Generating Station – BART Determination

1.0 INTRODUCTION
On July 6, 2005, the U.S. Environmental Protection Agency (EPA) published the final “Regional
Haze Regulations and Guidelines for Best Available Retrofit Technology Determinations” (the
“Regional Haze Rule” 70 FR 39104). EPA issued the Regional Haze Rule under the authority and
requirements of sections 169A and 169B of the Clean Air Act (CAA). Sections 169A and 169B
require EPA to address regional haze visibility impairment in 156 federally-protected parks and
wilderness areas (Class I Areas). As mandated by the CAA, the Regional Haze Rule requires
certain large stationary sources to install the best available retrofit technology (BART) to reduce
emissions of pollutants that may impact visibility in a Class I Area.
The Regional Haze Rule requires certain States, including Oklahoma, to develop programs to
assure reasonable progress toward meeting the national goal of preventing any future, and
remedying any existing, impairment of visibility in Class I Areas. The Regional Haze Rule requires
states to submit a plan to implement the regional haze requirements (the Regional Haze SIP). The
Regional Haze SIP must provide for a BART analysis of any existing stationary facility that might
cause or contribute to impairment of visibility in a Class I Area. To address the requirements for
BART, Oklahoma must:
� Identify all BART-eligible sources within the State.
� Determine whether each BART-eligible source emits any air pollutant which may
reasonably be anticipated to cause or contribute to any impairment of visibility in a
Class I Area. BART-eligible sources which may reasonably be anticipated to cause or
contribute to visibility impairment are classified as BART-applicable sources.
� Require each BART-applicable source to identify, install, operate, and maintain BART
controls.
1.1 OG&E’s Muskogee Generating Station
OG&E’s Muskogee Generating Station is located at 5501 Three Forks Road near Muskogee,
Oklahoma. The station has a total of four (4) generating units designated as Muskogee Units 3, 4, 5
and 6. Muskogee Unit 3, which became operational in 1956, is a nominal 173-MW gas-fired unit.
Muskogee Units 4, 5 and 6 are nominal 572-MW (gross) coal-fired units. Construction of
Muskogee Units 4 & 5 commenced in the early 1970s, with Unit 4 coming on-line in 1977 and Unit
5 coming on-line in 1978. Construction commenced on Muskogee Unit 6 in 1980, and Unit 6
commenced commercial operation in mid-1984. All three coal-fired units at the Muskogee
Generating Station are dry bottom tangentially-fired pulverized coal (PC) boilers. The boilers fire
subbituminous coal as their primary fuel, and are equipped with electrostatic precipitators for
particulate control.
