   C.  Exceptions

       1.  Start-up Provision

§2307.C.1.a SIP effective to February 28, 2016.
OS065   §2307.C.1.a;LAd34;LA021.11;OS065;LR31:2442(10/20/2005)
          a. A four-hour start-up exemption from emission 
regulations may be authorized by the administrative 
authority for plants not subject to 40 CFR Part 60, Subpart 
G, as incorporated by reference in LAC 33:III.Chapter 30, 
which have been shut down. It is recognized that existing 
nitrogen oxide abatement equipment is effective only at 
normal operating temperatures. This provision allows the 
necessary time to bring up a facility from a cold start to near 
steady state condition. A report, in writing, explaining the 
conditions and duration of the start-up and listing the steps 
necessary to remedy, prevent, and limit the excess emissions, 
shall be submitted to the Office of Environmental 
Compliance, Emergency and Radiological Services 
Division, SPOC, within seven calendar days of the 
occurrence using the procedures provided in LAC 33:I.3925.

§2307.C.1.a SIP effective to February 28, 2016.
§2307.C.1.a as submitted to EPA August 14, 2009 [LA039.03] and resubmitted 
to EPA October 2015 [LA039.05], MM002 LR 33:2088 (October 20, 2007).

         a. A four-hour start-up exemption from emission
regulations may be authorized by the administrative
authority for plants not subject to 40 CFR Part 60, Subpart

shall be submitted to SPOC within seven calendar days of
the occurrence using the procedures provided in LAC 33:I.3925.

           b.  This provision is applicable to infrequent start ups only. Before the exemption can be granted the administrative authority must determine the excess emissions were not the result of failure to maintain or repair equipment. In addition, the duration of excess emission must be minimized and no ambient air quality standard may be jeopardized.

       2.  On-line Operating Adjustments.

§2307.C.2.a SIP effective to February 28, 2016.
OS065   §2307.C.2.a;LAd34;LA021.11;OS065;LR31:2442(10/20/2005)
         a. A four-hour exemption from emission regulations 
may be extended by the administrative authority to plants 
not subject to 40 CFR Part 60, Subpart G, as incorporated by 
reference in LAC 33:III.Chapter 30, where upsets have 
caused excessive emissions and on-line operating changes 
will eliminate a temporary condition. A report, in writing, 
explaining the conditions and duration of the upset and 
listing the steps necessary to remedy, prevent, and limit the 
excess emissions shall be submitted to the Office of 
Environmental Compliance, Emergency and Radiological 
Services Division, SPOC, within seven calendar days of the 
occurrence using the procedures provided in LAC 33:I.3925.

§2307.C.2.a as submitted to EPA August 14, 2009 [LA039.03] and resubmitted 
to EPA October 2015 [LA039.05], MM002 LR 33:2088 (October 20, 2007).

         a. A four-hour exemption from emission regulations
may be extended by the administrative authority to plants
not subject to 40 CFR Part 60, Subpart G, as incorporated by
reference in LAC 33:III.Chapter 30, where upsets have

excess emissions, shall be submitted to SPOC within seven
calendar days of the occurrence using the procedures
provided in LAC 33:I.3925.

           b.  This provision is applicable to infrequent on-line adjustments only. Before the exemption can be granted, the administrative authority must determine the excess emissions were not the result of failure to maintain or repair equipment.

           c.  In addition, the duration of excess emissions must be minimized and no ambient air quality standard may be jeopardized.

   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 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.
