Document Description
Rule 462 seeks to control emissions of volatile organic compounds (VOC) originating from bulk terminals and other facilities that load organic liquids into tank trucks, trailers, or railroad tank cars. Proposed Amended Rule (PAR) 462 partially implements Control Measure FUG-01 – Improved Leak Detection and Repair, of the 2022 Air Quality Management Plan by: 1) requiring monthly optical gas imaging (OGI) inspections; 2) requiring periodic source tests on vapor control systems at Class A facilities (facilities which load 20,000 gallons or more of organic liquids per day); 3) reducing VOC limits for vapor control systems at Class A facilities from 0.08 to 0.04 pound per 1,000 gallons of organic liquid transferred; and 4) adding new and updated definitions, and implementing other minor changes for consistency and clarity. Additionally, PAR 462 introduces a contingency measure as required by the federal Clean Air Act, which, if triggered, would require bi-weekly OGI inspections. Implementation of PAR 462 is anticipated to benefit public health and ambient air quality by reducing VOC emissions by 0.34 ton per day plus an additional 0.01 ton per day if the contingency measure is triggered.

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. PAR 462 will achieve VOC emission reductions through more stringent VOC limits and by requiring frequent OGI inspections, 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.
