Section 20.2.72.306 - SOURCE CLASS REQUIREMENTS

A. In addition to the general conditions of 20.2.72.305 NMAC, each permitted source listed in 20.2.72.501 NMAC (Table 2) shall also comply with the applicable source class requirements below:

(1) Requirements for source class category 1 - reciprocating internal combustion (IC) engines:

(a) Gas fuel shall be produced natural gas, sweet natural gas, liquid petroleum gas, or fuel gas. No gas fuel shall contain more than 0.1 grain of total sulfur per dry standard cubic foot. Liquid fuel shall be first run refinery grade diesel or No. 2 fuel oil that is not a blend containing waste oils or solvents and contains less than 0.3% by weight sulfur;

(b) Within ninety (90) days after initial start-up of the source, the owner or operator shall conduct NOx and carbon monoxide (CO) performance tests on one or more engines (turbines) at the facility to ensure the facility is in compliance with 20.2.72.300 NMAC - 20.2.72.399 NMAC and permit requirements, including emission limits and any applicable pollution control device reduction efficiency requirements for NOx. The Department shall specifically identify in the permit each engine or turbine subject to initial performance testing requirements. Tests shall be conducted in accordance with the requirements of Subsection C of 20.2.72.305 NMAC;

(c) Any engine which operates with a non-selective catalytic converter shall comply with the following requirements:

i. Any spark ignited gas-fired or any compression ignited dual fuel-fired engine shall be equipped and operated with an automatic air-fuel ratio (AFR) controller which maintains AFR in the range required to minimize NOx emissions, as recommended by the manufacturer; and

ii. The owner or operator shall make and maintain records to demonstrate that the manufacturer's or supplier's recommended maintenance is performed, including replacement of the oxygen sensor as necessary for oxygen-based AFR controllers, and cleaning, regeneration, and/or replacement of catalyst(s) as necessary to maintain at least the NOx reduction efficiencies across the catalyst bed that are specified in the permit.

B. Requirements for source class category 2 - turbines: The source must comply with Paragraphs 1 and 2 of Subsection A of 20.2.72.306 NMAC.
