Description of the source (including control equipment). Please see the attachments for source or process flow diagram:

The Mt. Poso Cogeneration Plant is located at 36157 Famoso Highway, Bakersfield, California. Since 1989 the Mt. Poso Cogeneration Plant, which consists of a coal/petrole um coke/biomass and tire derived fuel-fired base load 49.5 megawatt unit, has provided electrical power to help meet the growing needs of California as well as supplying steam to thermally enhance the oil recovery in a nearby oil field. For over 20 years of operation, the plant has consistently generated enough electricity to power over 35,000 homes, twenty-four hours a day, seven days a week, three hundred sixty five days a year. Pulverized coal/petroleum coke/biomass an d tire derived fuel is combusted in the boiler to create heat that generates pressurized steam used in the turbine. Combustion of coal produces emissions of sulfur dioxide (SO2), oxides of nitrogen (NOX), particulate matter (PM), carbon monoxide (CO), volatile organic compounds (VOC), and certain hazardous air pollutants (HAPs) in sufficient quantities to designate the facility as a Title V source of air pollutants. Particulate matter emissions from coal combustion are controlled by the use of a fabric collector. Sulfur dioxide emissions are minimized by pulverized limestone. Emissions of other gaseous pollutants are minimized through goo d combustion practices. The boiler exhaust is routed to the fabric collector. A si ngle induced draft fan draws the exhaust gases through the fabric collector and pushes the exhaust out a single stack to the atmosphere. The exhaust stack is a 170 feet tall. The unit is equipped with a continuous emission monitoring system (CEMS) at the exhaust stack outlet. The system provides data for reporting of emissions pursuant to the Title V Air Operating Permit. The CEMS includes an in-situ and extractive sampling system that delivers sample to the emission analyzers. The system measures and records the wet-basis concentrations of NOX and SO2. CO2 is recorded on a dry basis. Volumetric flow rate is also measured and recorded by the CEMS. The data acquisition system on the CEMS reports emissions in units of concentration and mass emission rates. Industry /SCC/NAIS: 221112 AFS #: FRS #: 110000481657
