001 Sulfur Compound Emissions; Existing Sources Emissions Standards. No person will allow sulfur oxides to be emitted from any existing fossil fuel burning equipment in excess of two and one half (2.5) pounds per million BTU input, maximum 2-hour average. For purposes of these regulations, “existing fossil fuel burning equipment” means equipment, machines, devices, articles, contrivances, or installations in operation prior to February 26, 1974; and, the heat input will be the aggregate heat content of all fuels whose products of combustion pass through a stack, or the equipment manufacturer's or designer's guaranteed maximum input, whichever is greater.
002 Nitrogen Oxides (Calculated as Nitrogen Dioxide) Emissions Standards for Stationary Sources. No owner or operator of an installation producing nitric acid, either as an end product or for use in intermediate steps in production of other products, will allow emissions of oxides of nitrogen (calculated as nitrogen dioxide) to exceed 5.5 pounds per ton of 100 percent nitric acid produced, or a concentration equivalent to 400 parts per million (ppm) by volume, whichever is more stringent. Compliance with the nitrogen oxides emission limit is determined using the arithmetic average of three contiguous one-hour periods. This will apply unless:
002.01 the installation is subject to 40 CFR § 60, Subpart Ga;
002.02 a more stringent oxides of nitrogen standard for nitric acid production is specified in the underlying requirements of an applicable federal rule; or
002.03 a more stringent oxides of nitrogen standard for nitric acid production is specified within a construction permit issued pursuant to this Title.
