Current through Register Vol. 50, No. 9, September 20, 2024

Section III-2307 - Emission Standards for the Nitric Acid Industry

A. Purpose. The purpose of this Subchapter shall be to limit the quantity of atmospheric emissions from nitric acid plants.

B. Scope. This Subchapter is applicable to all nitric acid production units not subject to NSPS in the state.

C. Reserved.

1. - 2.c. Repealed.

D. Emissions. The emission of nitrogen oxides, calculated as nitrogen dioxide, from nitric acid production units shall be limited to 6.5 pounds per ton (3.3 kilogram/metric ton) of 100 percent acid produced. This emission limitation is equivalent to a nitrogen dioxide concentration of approximately 500 ppm by volume.

E. Responsible Persons to Have Tests Made. The department may require any person responsible for emission of air contaminants to make or have made tests to determine the emission of air contaminants from any source, whenever the department has reason to believe that an emission in excess of that allowed by these regulations is occurring. The department may specify testing methods to be used in accordance with good professional practice. The department may observe the testing. All tests shall be conducted by reputable, qualified personnel. The department shall be given a copy of the test results in writing and signed by the person responsible for the tests.

F. The Department May Make Tests. The department may conduct tests of emissions of air contaminants from any source. Upon request of the department the person responsible for the source to be tested shall provide necessary sampling ports in stacks or ducts and such other safe and proper sampling and testing facilities, exclusive of instruments and sensing devices, as may be necessary for proper determination of the emission of air contaminants.

G. Degradation of Existing Emission Quality Restricted. Emissions whose quality as of the effective date of these regulations is higher than the standards set forth herein shall be maintained at the higher quality unless it can be affirmatively demonstrated to the department that a change in quality is justifiable and will not be contrary to the purpose of these regulations.

H. Measurement of Concentrations

1. The methods listed in LAC 33:III.1503.D.2, Table 4 or such equivalent method as may be approved by the department shall be utilized to determine oxide of nitrogen concentrations in stack gases.

2. Measurement equipment shall be periodically calibrated to comply with minimal American Bureau of Standards Criteria.
