Current through Register Vol. 50, No. 6, June 20, 2024

Section III-5105 - Prohibited Activities and Special Provisions

A. Prohibited Activities shall include the following.

1. After the effective date of any standard set forth in this Subchapter, no owner or operator shall construct or modify any stationary source subject to such standard without first obtaining written authorization from the administrative authority in accordance with this Subchapter.

2. After December 20, 1991, no owner or operator of any major source shall cause a violation of any ambient air standard listed in LAC 33:III.5112, Table 51.2, unless operating in accordance with LAC 33:III.5109.B.

3. No owner or operator subject to the provisions of this Subchapter shall build, erect, install, or use any article, machine, equipment, process, or method, the use of which conceals an emission that would otherwise constitute a violation of an applicable standard. Such concealment includes, but is not limited to, the use of diluents to achieve compliance with an emissions standard, and the piecemeal carrying out of an operation to avoid coverage by a standard that applies only to operations larger than a specified size.

4. No owner or operator subject to this Chapter shall fail to keep records, notify, report or revise reports as required under this Subchapter.

B. Special Provisions

1. The administrative authority may allow a certain complex within a facility to be considered as a separate source with regard to the requirements of this Subchapter, provided that the complex is used solely for research and development of new processes and/or products, and is not engaged in the manufacture of products for commercial sale.

2. Electric utility steam-generating units are exempt from the requirements of this Subchapter.

3. Each of the following emissions are exempt from the requirements of this Subchapter:

a. emissions from the combustion of Group 1 virgin fossil fuels;

b. emissions from the combustion of Group 2 virgin fossil fuels vented from a stack that has downwash minimization stack height or a height approved by the department; and

c. emissions from the combustion of gas streams with a Btu value of greater than 7,000 Btu/lb that are generated by onsite operations, collected by a fuel gas system as defined in 40 CFR Part 63, Subpart G, and used as fuel.

4. Any source, as defined in accordance with rules promulgated by the United States Environmental Protection Agency under provisions in Section 112(i)(5) of the federal Clean Air Act, that is in compliance with an enforceable commitment approved by the administrative authority* to achieve early reductions of 90 percent or more (95 percent for particulates), or that has demonstrated early reductions of 90 percent or more (95 percent for particulates), in accordance with such rules, shall be exempt from MACT requirements under LAC 33:III.5109.A. The term of exemption shall extend until such time as the compliance extension granted by the administrative authority or the U.S. Environmental Protection Agency has expired, or until nine years from the anticipated date of promulgation of applicable federal MACT standards according to the schedule published by the U.S. Environmental Protection Agency in accordance with Section 112(e)(3) of the federal Clean Air Act, whichever date is earlier. Under no circumstances shall this provision be used to grant an exemption to a source under conditions that do not result in a net air quality benefit for the state of Louisiana, as determined by the administrative authority. Under no circumstances shall the granting of such an exemption to a source relieve any source of other obligations under state or federal law.

5. In accordance with R.S. 30:2060, except under circumstances that may reasonably be expected to pose a threat to human health, whether or not such units are in a contiguous area or under common control, in determining the applicability of emission standards or technical control standards the administrative authority shall not aggregate:

a. emissions from any oil or gas exploration or production well and its associated equipment;

b. emissions from any pipeline compressor or pump station; or

c. emissions from other similar units.

6. The emissions from the remediation of a RCRA, CERCLA, or any nonregulated inactive or abandoned waste site cleanup shall be exempt from the ambient air standards of LAC 33:III.5112, Table 51.2, upon approval of the cleanup plan by the administrative authority.

7. Emissions from the combustion of wood residue fuel from pulp and paper mills are exempt from the provisions of LAC 33:III.5109.
