Document Description
Proposed Amended Rule 1134 applies to stationary gas turbines that are not subject to SCAQMD Rule 1135 - Emissions of Oxides of Nitrogen from Electricity Generating Facilities, or located at petroleum refineries. PAR 1134 is proposing to: 1) expand applicability to include stationary gas turbines that were not previously required to comply with Rule 1134; 2) update the NOx and ammonia emission limits for stationary gas turbines to comply with Best Available Retrofit Control Technology; 3) transition all monitoring, reporting, and record keeping requirements in Rule 1134 to new SCAQMD Rule 113 - MRR Requirements for NOx and SOx Sources, upon its adoption; 4) establish new exemptions for low-use equipment, certain existing combined cycle gas turbines, and emergency standby gas turbines; 5) provide relief from having to comply with ammonia requirements for turbines that do not use ammonia for controlling NOx emissions; and 6) revise existing exemptions to remove obsolete provisions. The proposed project is estimated to reduce NOx emissions by 2.8 ton per day after implementation of BARCT limits. The Draft SEA indicated that while reducing NOx emissions is an environmental benefit, secondary significant adverse environmental impacts are also expected for the topic area of hazards and hazardous materials. Some facilities affected by PAR 1134 may be identified on lists compiled by DTSC per Government Code Section 65962.5.
