Proposed Amended Rules 1133, 1133.1, 1133.2, and 1133.3

Proposed Amended Rule (PAR) 1133, PAR 1133.1, PAR 1133.2, and PAR 1133.3 are designed to implement Best Control Measure-10 (BCM-10) from the South Coast Air Basin Attainment Plan for the 2012 Annual PM2.5 Standard to further reduce emissions of volatile organic compounds (VOC) and ammonia from chipping and grinding operations, co-composting operations, and composting operations by regulating the supply of uncomposted greenwaste for direct land application. PAR 1133 establishes restrictions and prohibitions on suppliers of uncomposted greenwaste for direct land application unless uncomposted greenwaste is applied in a manner to minimize VOC and ammonia emissions. PAR 1133.1, PAR 1133.2, and PAR 1133.3 contain the information gathering elements formerly located within Rule 1133 to enable PAR 1133 to implement BCM-10. Additionally, PAR 1133.2 will introduce composting best management practices for previously uncontrolled existing co-composting operations. Implementation of the proposed project will benefit public health and ambient air quality by reducing VOC emissions by 2.34 tons per day and reducing ammonia emissions by 0.19 ton per day from approximately 98 facilities.
