The Louisiana Department of Environmental Quality is taking public comment until Sept. 4 on air permitting for an 84-MW, gas-fired power project of the Louisiana Energy and Power Authority (LEPA).
The department’s Office of Environmental Services is accepting written comments on an initial Part 70 (Title V) operating permit, an initial Prevention of Significant Deterioration permit, an initial Acid Rain permit, an initial Clean Air Interstate Rule permit and an Environmental Assessment Statement for the Louisiana Energy and Power Authority for the Morgan City Power Plant.
“[LEPA] requested authorization to construct and operate the Morgan City Power Plant, a proposed combined cycle combustion turbine electricity generating station, in Morgan City, Louisiana,” said an LDEQ notice. “The Morgan City Power Plant will consist of one (1) natural gas fired combustion turbine equipped with a heat recovery steam generator (HRSG) capable of producing 84 megawatts (MW) of gross electrical power, one (1) 2,000 kilowatt (kW) emergency diesel generator to generate electricity to operate critical systems when power is not otherwise available, one (1) 380 horsepower (HP) diesel-fired firewater pump which will be used as a back-up to service the fire protection needs of the new unit, and one (1) 20,000 gallon per minute evaporative two-cell cooling tower for cooling the circulating water used to extract heat from the steam turbine’s exhaust steam.”
The combustion turbine will be equipped with a water injection system to reduce NOx emissions. The HRSG will include a Selective Catalyst Reduction system with ammonia injection to reduce NOx emissions, and an oxidation catalyst for the control of carbon monoxide emissions.
