SU8PART K: PROCESS EMISSION SOURCES Section 217.301 Industrial Processes a) New Industrial Processes. No person shall cause or allow the emission of nitrogen oxides Into the atmosphere from an/ new ' process producing products of organic nitrations and/or oxidations using nitric acid to exceed the following standards and limitations: 1) 2.S kg of nitrogen oxides (expressed as nitrogen dioxide) per metric tonne of nitric acid (100 percent acid basis) used in such new process (S.O lbs/T). 2) Visible emissions In excess of S percent opacity. b) Existing Industrial Processes. No person shall cause or allow the emission of nitrogen oxides Into the atmosphere from an/ existing process producing products of organic ".nitrations and/or oxidations using.nitric . acid to exceed 5.0 kg of nitrogen oxides (expressed as nttrogen dioxide) per metric tonne of nitric acid (100 percent acid basis) used In such process (10.0 lbs/T). c) Exemption. Subsections (a) and (b) of this ' rule shall not apply to any industrial process using less than 90.7 metric tonnes (100 tons) of nitric acid (too percent acid basis) annually or which produces less than 907 kg (1 ton) of nitrogen oxides (expressed as nitrogen dioxide) per year. SU8PART 0: CHEMICAL MANUFACTURE Section 217.381 Nitric Acid Manufacturing Processes a) New Weak Nitric Acid Processes. No person Shall cause or allow the emission of nitrogen ' oxides Into the atmosphere from any new weak nitric acid manufacturing process to exceed the following standards and limitations: 1) 1.5 kg of nitrogen oxides (expressed as nitrogen dioxide) per metric tonne of acid produced (100 percent acid basts) (1.0 lbs/T); 2) Visible emissions In excess of-S percent opacity: 3) 0.05 kg of nitrogen oxides (expressed as nitrogen dioxide) per metric tonne of acid produced (loo percent acid basis) from any acid storage tank vents (0.1 lbs/T). b) Existing Weak Nitric Acid Processes.- "No person shall cause or allow the.emission of nitrogen oxides into the atmosphere from any existing weak nitric acid manufacturing process to exceed the following standards and limitations: 1) 2.75 kg of nitrogen oxides (expressed as nitrogen dioxide) per metric tonne of acid-produced (100 percent acid basis) (5.5 lbs/T): 2) Visible emissions In excess of 5 percent opacity: 3) 0.1 kg of nitrogen oxides (expressed as nitrogen dloxtde) per metric tonne'of ` acid produced (100 percent acid ba'sis) from any acid storage tank vents (0.2 lbs/T). :- c) Concentrated Nitric Acid Processes.
