Document Description
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.

Type, Section or Code
15061(b)(3) ; 15308
Reasons for Exemption
South Coast AQMD, as Lead Agency, has reviewed the proposed project pursuant to: 1) CEQA Guidelines Section 15002(k) – General Concepts, the three-step process for deciding which document to prepare for a project subject to CEQA; and 2) CEQA Guidelines Section 15061 – Review for Exemption, procedures for determining if a project is exempt from CEQA. The proposed project, PAR 1133, PAR 1133.1, PAR 1133.2, and PAR 1133.3, will achieve emission reductions of VOC and ammonia through requiring facilities to follow the best management practices when conducting composting, chipping, and grinding activities, which can be accomplished without physical modifications; thus, it can be seen with certainty that implementing the proposed project would not cause a significant adverse effect on the environment. Therefore, the proposed project is exempt from CEQA pursuant to CEQA Guidelines Section 15061(b)(3) – Common Sense Exemption. The proposed project is also categorically exempt from CEQA pursuant to CEQA Guidelines Section 15308 – Actions by Regulatory Agencies for Protection of the Environment, because PAR 1133, PAR 1133.1, PAR 1133.2, and PAR 1133.3 are intended to further protect or enhance the environment by improving public health and air quality through anticipated emission reductions of VOC and ammonia. Further, there is no substantial evidence indicating that any of the exceptions to the categorical exemption set forth in CEQA Guidelines Section 15300.2 – Exceptions, apply to the proposed project.
