South Coast Air Quality Management District: air quality.
The bill requires covered facilities to implement substantial changes by January 1, 2027. These include maintaining sufficient fencing and limiting the height of open storage piles to eight feet if situated within 500 feet of sensitive receptors. The prescribed measures aim to reduce the risk of PM10 emissions exceeding established thresholds. From July 1, 2027, covered facilities with a demonstrable history of high PM10 emissions must enclose their open storage piles and undergo monthly inspections by the SCAQMD until they demonstrate consistent compliance with emissions standards.
Senate Bill 526, introduced by Senator Menjivar, aims to enhance air quality management in the South Coast Air Quality Management District (SCAQMD) by updating existing regulations concerning particulate matter (PM10) emissions, specifically from aggregate and cement operations. The bill mandates that the SCAQMD board revise Rule 1157 to refine operational controls and improve data collection related to PM10 emissions. Additionally, it sets forth specific actions required of covered facilities within proximity of sensitive receptors, such as residences and schools, to minimize airborne pollutant concentrations.
While the bill focuses on public health and environmental protection, it may create contention regarding the financial implications for aggregate operation owners, as they may incur costs from compliance obligations. Critics might argue that the bill imposes undue burdens on local facilities, while supporters emphasize the importance of stringent air quality regulations to protect community health, especially in areas near sensitive receptors. The requirement for a monthly inspection could be seen as a regulatory overreach by some stakeholders, who may prefer a more flexible approach to compliance monitoring.
