Current through Register Vol. 50, No. 6, June 20, 2024
Section III-5609 - Preplanned Strategies RequiredA. Any person responsible for operation of a source as listed in LAC 33:III.5611, Tables 5, 6, and 7 shall prepare standby plans for the reduction of emissions during periods of Air Pollution Alert, Air Pollution Warning and Air Pollution Emergency. Standby plans shall be designed to reduce or eliminate emissions in accordance with the objectives as set forth in LAC 33:III.5611, Tables 5, 6, and 7. 1. Alert Level a. The alert level is the concentration of pollutant at which the first stage of control action is taken. An alert will be declared when any one of the following levels is reached at any monitoring site: i. SO2-800 [MICRO]g/m3 (0.3 ppm), 24-hr average;ii. PM10-350 [MICRO]g/m3, 24-hr average;iii. CO-17 mg/m3 (15 ppm), 8-hr average;iv. Oxidant (O3)-400 [MICRO]g/m3 (0.2 ppm), 1-hr average;v. NO2-1130 [MICRO]g/m3 (0.6 ppm), 1-hr average 282 [MICRO]g/m3 (0.15 ppm), 24-hr average; and meteorological conditions indicate that the pollutant concentrations will remain at the above levels 12 hours or more or increase unless control actions are taken.b. When the administrative authority declares an Air Pollution Alert, any person responsible for the operation of sources of air pollution as listed in LAC 33:III.5611, Table 5 shall take such action as prescribed by LAC 33:III.5611, Table 5 and shall activate the preplanned abatement strategy listed in LAC 33:III.5611 for an Air Pollution Alert.2. Warning Level a. The warning level indicates that pollutant concentration levels are continuing to rise and further control measures are needed. A warning will be declared when any one of the following levels is reached at any monitoring site:i. SO2-1600 [MICRO]g/m3 (0.6 ppm), 24-hr average;ii. PM10-420 [MICRO]g/m3, 24-hr average;iii. CO-34 mg/m3 (30 ppm), 8-hr average;iv. Oxidant (O3)-800 [MICRO]g/m3 (0.4 ppm), 1-hr average;v. NO2-2260 [MICRO]g/m3 (1.2 ppm), 1-hr average 565 [MICRO]g/m3 (0.30 ppm), 24-hr average; and meteorological conditions indicate that the pollutant concentrations will remain at the above levels 12 hours or more or increase unless control actions are taken.b. When the administrative authority declares an Air Pollution Warning, any person responsible for the operation of sources of air pollution as listed in LAC 33:III.5611, Table 6 shall take such action as prescribed by LAC 33:III.5611, Table 6 and shall activate the preplanned strategy listed in LAC 33:III.5611 for an Air Pollution Warning.3. Emergency Level a. The emergency level indicates that pollutant concentrations are increasing to dangerous levels and that the most stringent control actions are necessary in order to assure a reduction in pollutant concentration levels. An emergency will be declared when any one of the following levels is reached at any monitoring site: i. SO2-2100 [MICRO]g/m3 (0.8 ppm), 24-hr average;ii. PM10-500 [MICRO]g/m3, 24-hr average;iii. CO-46 mg/m3 (40 ppm), 8-hr average;iv. Oxidant (O3)-1000 [MICRO]g/m3 (0.5 ppm), 1-hr average;v. NO2-3000 [MICRO]g/m3 (1.6 ppm), 1-hr average 750 [MICRO]g/m3 (0.4 ppm), 24-hr average; and meteorological conditions indicate that the pollutant concentrations will remain at the above levels 12 hours or more or increase unless control actions are taken.b. When the administrative authority declares an Air Pollution Emergency, any person responsible for the operation of sources of air pollution as listed in LAC 33:III.5611, Table 7 shall take such action as prescribed by LAC 33:III.5611, Table 7 and shall activate the preplanned abatement strategy listed in LAC 33:III.5611 for an Air Pollution Emergency.La.
