Current through Register Vol. 28, No. 1, July 1, 2024

Section 1117-3.0 - Minimum Emission Monitoring Requirements for Existing Sources

3.1 Applicability - The person responsible for existing sources listed in 3.0 of this regulation shall install, calibrate, operate, and maintain all monitoring equipment necessary for the continuous monitoring of the pollutants specified in 3.0 of this regulation for the applicable source category and shall complete the installation and performance tests of the above equipment and begin monitoring and recording within 18 months of the date of plan approval or promulgation.

3.2 Fuel Burning Equipment - Fuel burning equipment except as provided in 3.2 through 3.4 of this regulation, with an annual average capacity factor of greater than 30%, as reported to the Federal Power Commission for calendar year 1974, or as otherwise demonstrated to the Department by the owner or operator, shall conform with the following monitoring requirements:

3.2.1 A continuous monitoring system for the measurement of opacity which meets the performance specifications of 4.1.1 of this regulation shall be installed, calibrated, maintained, and operated in accordance with the procedures of 4.0 of this regulation by the owner or operator of any such equipment of greater than 250 million BTU per hour heat input (1.05 million kilogram-calories per minute) except where:

3.2.1.1 Gaseous fuel is the only fuel burned, or

3.2.1.2 Oil or a mixture of gas and oil are the only fuels burned and source is able to comply with the applicable particulate matter and opacity regulations without utilization of particulate matter collection equipment.

3.2.1.3 Waste heat boilers such as carbon monoxide boilers unless they derive greater than 250 million BTU per hour heat input from the firing of auxiliary fuel.

3.2.2 A continuous monitoring system for the measurement of sulfur dioxide which meets the performance specification of 4.1.3 of this regulation shall be installed, calibrated, maintained, and operated on any fuel burning equipment of greater than 250 million BTU per hour input which has installed sulfur dioxide control equipment.

3.2.3 A continuous monitoring system for the measurement of nitrogen oxides which meets the performance specification of 4.1.2 of this regulation shall be installed, calibrated, maintained, and operated on any fuel burning equipment or combination or such equipment discharging effluents through a common stack of greater than 1000 million BTU per hour heat input, (4.2 million kilogram-calories per minute) when such equipment is located in an Air Quality Control Region which is classified as Priority I with respect to nitrogen dioxide. This requirement shall not be applicable to any source owner or operator who demonstrates during source compliance tests as required by the Department that such a source emits nitrogen oxides at levels 30% or more below the applicable New Source Performance Standard.

3.2.4 A continuous monitoring system for the measurement of the percent oxygen or carbon dioxide shall be installed, calibrated, operated, and maintained on fuel burning equipment where measurements of oxygen or carbon dioxide in the flue gas are required to convert either sulfur dioxide or nitrogen oxides continuous emission monitoring data, or both, to units of the New Source Performance Standard. Measurement of the percent oxygen or carbon dioxide shall meet the performance specifications of 4.1.4 or 4.1.5 of this regulation.

3.3 Sulfuric Acid Plants - Each sulfuric acid plant of greater than 300 tons per day production capacity shall install, calibrate, maintain and operate a continuous monitoring system for the measurement of sulfur dioxide which meets the performance specifications 4.1.3 of this regulation for each sulfuric acid producing facility within such plant.

3.4 Fluid bed catalytic cracking unit catalyst regenerators at petroleum refineries. Each catalyst regenerator for fluid bed catalytic cracking units of greater than 20,000 barrels per day fresh feed capacity shall install, calibrate maintain, and operate a continuous monitoring system for the measurement of opacity which meets the performance specifications of 4.1.1 of this regulation.
