Title

Proposed Amended Rule (PAR) 1135 – Emissions of Oxides of Nitrogen from Electricity Generating Facilities

Description

PAR 1135 proposes revisions specific to electric generating units located on Santa Catalina Island which will: 1) remove the nitrogen oxides (NOx) emission limit of 50 tons per year (tpy) because the January 1, 2024 compliance date has passed; 2) delay the compliance dates of the NOx emission limits of: a) 45 tpy from January 1, 2025 to January 1, 2027, and b) 13 tpy from January 1, 2026 to January 1, 2030 (with a three-year extension option to meet 13 tpy by January 1, 2033) to allow for the installation of no more than three new diesel internal combustion engines with a cumulative rating of 5.5 megawatts (MW); 3) establish new 30 tpy and six tpy NOx emission limits with compliance dates of January 1, 2028 and January 1, 2035 respectively (with a three-year extension option to meet 6 tpy by January 1, 2038); 4) require the installation of Santa Catalina Island near zero emission (NZE) and/or zero emission (ZE) electric generating units by January 1, 2030 (with a three-year extension option to meet by January 1, 2033); 5) prohibit the installation of equipment after January 1, 2028 that does not meet the definition of a Santa Catalina Island NZE electric generating unit or a Santa Catalina Island ZE electric generating unit; 6) require all prime power diesel internal combustion engines installed prior to the Date of Adoption to be removed from service by January 1, 2030 or six month any applicable extensions; and 7) establish provisions for monitoring, reporting, and recordkeeping for NZE electric generating units. The Draft SEA concluded that significant and unavoidable adverse environmental impacts may occur for the topic of air quality during operation due to interim emission reductions foregone, interim exceedances of the PM2.5 and PM10 ambient air quality standards, and interim health risk impacts. However, upon full implementation, PAR 1135 would be expected to reduce NOx emissions by 65.3 tpy by January 1, 2038. No other significant adverse impacts were identified. Facilities subject to the proposed project may be identified on lists compiled by the California Department of Toxic Substances Control per Government Code Section 65962.5. However, implementation of PAR 1135 is not expected to alter the status of the facilities and other locations on the lists.
