PNM Rio Bravo Generating Station, 725 Electric Avenue SE, Albuquerque, NM 87105
RBGS generates electricity (SIC Code 4911, NAICS 221112) with a nominal 150 MW, GE7FA simple-cycle combustion turbine powered primarily with pipeline quality natural gas and with low-sulfur #2 fuel oil as the secondary fuel. Emissions controls on the turbine include dry low-NOx burners for natural gas and water injection for #2 fuel oil combustion. Annual hours of operation limit on each fuel type are 7,320 hours per year for natural gas and 1,440 hours per year for #2 fuel oil. Auxiliary equipment includes a diesel-powered fire pump engine, one aboveground storage tank for fuel oil, water storage tanks, electrically driven fuel gas compressors, and a control house/maintenance building.
Permit Application #2093-RN1-M1 is for the significant permit modification of Title V Operating Permit #2093-RN1. PNM has requested to incorporate one combined New Source Review and Prevention of Significant Deterioration (NSR/PSD) permit into the Title V Operating permit. The NSR/PSD permit, which has already been approved, was issued September 7, 2017 (PSD/CP Permit #0694-M3). The NSR/PSD permit has previously been presented to the public during a public comment period which ran from June 22, 2017 to July 22, 2017. The COA EHD’s decision to grant or disapprove the Title V Permit modification will be based on review of the application received on August 30, 2018, which was deemed complete on October 28, 2018, and Air Quality Control Regulations for Albuquerque/Bernalillo County, as amended.
Changes made in the PSD/CP Permit #0694-M3 and requested for incorporation in the Title V permit in Permit Application #2093-RN1-M1 include:
- Add one (1) 75- horsepower, diesel-fired, emergency power generator. The emergency generator is currently restricted to 500 hours per year including 100 hours per year limit on maintenance operation.
The Permit Application #2093-RN1-M1 also requests to revise some of the conditions, specifically:
- Change the frequency of visible emissions monitoring requirements for a fire pump engine and the emergency power generation engine from quarterly to annually.
Anticipated date to make a decision: April 30, 2021
