In February, the South Coast Air Quality Management District (SCAQMD) held its first working group meetings for Proposed Rules (PR) 1109.1 (February 21) and Proposed Amended Rule (PAR) 1134 (February 22). PR 1109.1 - Refinery Equipment - will establish NOx emission limits for equipment at refineries. PAR 1134 - Emissions of Oxides of Nitrogen from Stationary Gas Turbines - will also establish NOx emission limits for facilities with stationary gas turbines. The proposed rule changes are aimed at facilities transitioning out of the sunsetting Regional Clean Air Incentives Market (RECLAIM) program.

Previously in the SCAQMD, the aforementioned refinery equipment and stationary gas turbines were not subject to Rules 1109.1 or 1134 if they were located at a facility that was part of the RECLAIM program. The working group meetings focused on updating the rules to a command and-control regulatory structure that requires Best Available Retrofit Control Technology (BARCT) controls for the applicable equipment. At the meetings, SCAQMD proposed implementing an expedited BARCT schedule for the largest emitters to comply with Assembly Bill (AB) 617, which aims to reduce air pollution through a variety of methods that are to be implemented at the air district level. The compliance schedule for PRs 1109.1 and 1134 will likely be staged over a multi-year period, taking into consideration equipment size and the number of units at a facility.

The next working group meeting to discuss PAR 1134 will be held at SCAQMD on April 26, 2018. For more information regarding compliance with the proposed rule changes, please contact our Irvine office at (949) 567-9880 or visit the District's website.
