100 GENERAL

101 PURPOSE: To limit emissions of nitrogen oxides (NOx) to the atmosphere from the operation of stationary gas turbines.

102 APPLICABILITY: This rule applies to all stationary gas turbines with ratings equal to or greater than 0.3 megawatt (MW) output, or 3 MMBTU/hr input and operated on gaseous and/or liquid fuel.

110 EXEMPTION - EMERGENCY STANDBY UNITS: Except for Section 303.3, the provisions of Section 300 shall not apply to the operation of gas turbines used to provide emergency electrical power, emergency water pumping for flood control or fire fighting, emergency potable water pumping, or emergency sewage pumping provided the following requirements are met;

111 EXEMPTION - REMOVAL FROM SERVICE: The provisions of Section 300 shall not apply to any unit that will be removed from service prior to May 31, 1997 provided that the owner or operator complies with the requirements specified in Section 401.4.

112 EXEMPTION - LABORATORY UNITS: The provisions of Sections 301 and 302 shall not apply to laboratory gas turbine units used in research and testing for the advancement of gas turbine technology.

113 EXEMPTION - STARTUP/SHUTDOWN PERIOD: The provisions of Sections 301 and 302 shall not apply to the period of time for the purpose of startup and shutdown of a gas turbine. This period is not to exceed one hour for startup and one hour for shutdown.

200 DEFINITIONS

201 BEST AVAILABLE RETROFIT CONTROL TECHNOLOGY (BARCT): Best Available Retrofit Control Technology, as defined in Section 40406 of the California Health and Safety Code, is "an emission limitation that is based on the maximum degree of reduction achievable, taking into account environmental, energy, and economic impacts by each class or category of sources." These limits are specified in Section 302.

202 CONTROL SYSTEM OPERATING PARAMETERS: The operating parameters that the Air Pollution Control Officer deems necessary to analyze when determining compliance, including, but not limited to, ammonia and exhaust gas flow rates, the exhaust gas temperature, and the water or steam injection rate.

203 EMERGENCY STANDBY UNIT: Any gas turbine unit which is used exclusively for either emergency purposes or maintenance operations. Maintenance operations shall be limited to one hundred (100) or fewer hours per calender year with the total hours not to exceed 200 hours. A unit is used for emergency purposes if the unit operates to provide:

204 MAINTENANCE OPERATION: The use of an emergency standby unit and fuel system during testing, repair and routine maintenance to verify its readiness for emergency standby use.

205 PEAK LOAD: Means 100 percent of the manufacturer's design capacity of the gas turbine.

206 POWER AUGMENTATION: Any increase in the gas turbine shaft output and/or decrease in gas turbine fuel consumption by the addition of energy recovered from exhaust heat.

207 RATING: The continuous megawatt (MW) rating or mechanical equivalent specified by a manufacturer for a gas turbine without power augmentation.

208 REASONABLY AVAILABLE CONTROL TECHNOLOGY (RACT): Reasonably Available Control Technology means "the lowest emission limitation that a unit is capable of meeting by the application of control technology that is reasonably available considering technological and economic feasibility," as specified in Section 301.

209 RETROFITTING: Any physical change to an emissions unit necessary for reducing NOx emissions to comply with the NOx emissions limits specified in Sections 301 through 302 of this rule, including, but not limited to, burner replacement, and the addition of emissions control equipment. Changes in the method of operation is not considered to be retrofitting.

210 SELECTIVE CATALYTIC REDUCTION (SCR): Selective Catalytic Reduction is a post combustion NOx control technique. A reducing agent (for example: ammonia) is used in a gas- phase reaction with oxides of nitrogen in the presence of a catalyst to form nitrogen and water.

211 STATIONARY GAS TURBINE OR UNIT: Any gas turbine that remains or will remain at a stationary source for:

212 STATIONARY SOURCE: Any building, structure, facility, or installation which emits or may emit any affected pollutant directly or as a fugitive emission.
