Document Description
SCAQMD staff is proposing amendments to Rule 1146 - Emissions of Oxides of Nitrogen from Industrial, Insitutional and Commercial Boilers, Steam Generators, and Process Heaters to reduce the allowable NOx emission limits from 30 parts per million (ppm) to 12 ppm, nine, or five ppm, depending on equipment size, operational characteristics, and energy efficiency. The proposed amendments to Rule 1146 will also propose NOx compliance limits for units burning landfill or digester gasses at 25 ppm and 15 ppm, respectively. Other changes are proposed that include: 1) establishing annual tune-up procedures and monthly maintenance procedures; 2) limiting timeframe for derating equipment; and 3) allowing a 30 ppm NOx compliance limit for low fuel usage equipment by January 1, 2015, or until burner replacement, which ever occurs later. Other minor changes are proposed for clarity and consistency throughout the rule. The initial study identified "air quality" and "hazardous materials" as the only areas that may be adversely affected by the proposed project. Impacts to these environmental areas will be further analyzed in the Draft EA.
