Bill > SB526

This bill addresses air quality regulations for the South Coast Air Quality Management District, focusing specifically on particulate matter (PM10) emissions from aggregate operations. The bill requires the district to update Rule 1157 to improve air quality and data collection, mandating that owners or operators of covered facilities within 500 feet of sensitive receptors (which include residences, schools, hospitals, parks, and daycare facilities) take several actions. By January 1, 2027, these facilities must maintain fencing around their property that is at least 6 inches taller than their highest storage pile, keep open storage piles no taller than 8 feet, develop and operate a fence-line monitoring system, and cease activities if PM10 emissions reach a certain threshold. Additionally, facilities must display signage about the rule and provide public notice if emissions exceed limits. Starting July 1, 2027, facilities with a history of high PM10 emissions near sensitive receptors must fully enclose their open storage piles, and the district will conduct monthly inspections until emissions remain below the threshold for three consecutive months. The bill is designed to address unique air quality concerns in the South Coast Air Basin and includes provisions for potential state reimbursement of local implementation costs.
