SCAQMD Proposed Amended Rule 1135

The South Coast Air Quality Management District (SCAQMD) held its first working group meeting on January 11, 2018, for Proposed Amended Rule (PAR) 1135 - Emissions of Oxides of Nitrogen from Electric Power Generating Systems. The purpose of this rule is to reduce NOx emissions from equipment at Electricity Generating Facilities (EGFs), including turbines/duct burners, boilers, and internal combustion engines. The proposed rule changes are aimed at facilities transitioning out of the Regional Clean Air Incentives Market (RECLAIM) program and are expected to impact 150 pieces of equipment from 29 facilities.

Previously, most EGFs in the SCAQMD were not subject to Rule 1135 because they were part of the RECLAIM program. Those EGFs were subject to Rule 2009, which required EGFs to submit a compliance plan demonstrating that all RECLAIM NOx emitting equipment (excluding Rule 219 equipment) would achieve best available retrofit control technology (BARCT) emission levels. BARCT levels were determined on a case-by-case basis for each equipment unit, based on technical and cost-effectiveness evaluations. PAR 1135, which would apply to these EGFs once they are out of RECLAIM, would implement new BARCT and NOx emission limits. The working group meeting focused on initial concepts for facilities exiting RECLAIM, an implementation timeline, and potential issues. The public hearing for the rule is currently scheduled for November 2018.

The next working group meeting will be held on February 24, 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.
