SJVAPCD Proposed Regulatory Measures in 2018 PM2.5 Attainment Plan
The San Joaquin Valley Air Pollution Control District (SJVAPCD) recently adopted the 2018 Plan for the 1997, 2006, and 2012 PM2.5 Standards. As part of the District’s attainment strategy, several new regulatory measures were proposed. The table below summarizes the District rules affected and the proposed timeline. The most relevant proposed changes are summarized below.
|Rule||Public Process Begins||Action Date||Implementation Begins|
|Rule 4311: Flares||2018||2020||2023|
|Rule 4306: Boilers, Steam Generators, and Process Heaters – Phase 3;
Rule 4320: Advanced Emission Reduction Options for Boilers, Steam Generators, and Process Heaters Greater Than 5.0 MMBtu/hr
|Rule 4702: Internal Combustion Engines||2019||2020||2024|
|Rule 4354: Glass Meling Furnaces||2020||2021||2023|
|Rule 4352: Solid Fuel Fired Boilers, Steam Generators and Process Heaters||2020||2021||2023|
|Rule 4550: Conservation Management Practices||2021||2022||2024|
|Rule 4692: Commercial Under-Fired Charbroiling||2019||2020||2024|
|Rule 4901: Wood Burning Fireplaces and Wood Burning Heaters||2019||2019||2019|
Rule 4311: Flares
Under Rule 4311, flare operators at Major Sources (Title V facilities) are required to submit flare minimization plans, perform extensive monitoring and recordkeeping, and submit reports of planned and unplanned flaring events to the District. Proposed changes include additional ultra-low-nitrogen oxide (NOx) flare emission limits, additional flare minimization requirements, and expanding the rule applicability to flares located at Minor Sources (non-Title V facilities).
Rule 4306: Boilers, Steam Generators, and Process Heaters – Phase 3; Rule 4320: Advanced Emission Reduction Options for Boilers, Steam Generators, and Process Heaters Greater Than 5.0 MMBtu/hr
Rules 4306 and 4320 apply to boilers, steam generators, and process heaters with a heat input greater than 5.0 million British thermal units per hour (MMBtu/hr). This equipment can be found at a wide range of industries. Current emission limits vary depending on the size of the unit and range between 5 and 12 parts per million (ppm) NOx. Proposed NOx emission limits could be reduced to as low as 2 to 3.5 ppm, depending on the unit.
Rule 4702: Internal Combustion Engines
Rule 4702 applies to internal combustion engines rated at 25 brake horsepower (bhp) or greater. Proposed changes to the rule would lower existing NOx limits, depending on the engine, to as low as 5 ppm.
Rule 4354: Glass Melting Furnaces
Proposed changes to Rule 4354 will evaluate the feasibility of ultra-low-NOx control technologies, potentially lowering the NOx emission limit from 1.5 to 1.0-1.2 pounds per ton of glass pulled.
Rule 4352: Solid Fuel Fired Boilers, Steam Generators and Process Heaters
Units subject to Rule 4352 fire on a variety of solid fuels: coal, petroleum coke, biomass, tire-derived fuel, and municipal solid waste facilities. The proposed changes will evaluate the feasibility of lower NOx emission levels, particularly at municipal waste-fired units.
