Summary of Rule Amendment Efforts
District Rule 4354 limits emissions of NOx, CO, VOC, SOx, and PM10 emissions from glass melting furnaces. The District adopted Rule 4354 in 1994, and in the continuous effort to improve air quality in the Valley, the District has adopted numerous amendments to Rule 4354 that have resulted in significant reductions in emissions.
On December 16, 2021, the District Governing Board adopted amendments to Rule 4354 to include even more stringent NOx, PM10, and SOx emission limits for glass melting facilities operating in the Valley. The adopted regulatory amendments satisfy the District's control measure commitment in the District's 2018 PM2.5 Plan, and go beyond the commitments in the Plan to support expeditious attainment of the health-based federal PM2.5 and ozone air quality standards. In addition, the adopted amendments address commitments included in Board/CARB-approved South Central Fresno Community Emissions Reduction Program developed through the AB 617 community engagement process.
