La. Admin. Code tit. 33 § III-5109

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

Section III-5109 - Emission Control and Reduction Requirements and Standards

A. Maximum Achievable Control Technology (MACT) Requirements

1. The owner or operator of any major source that emits or is permitted to emit a Class I or Class II toxic air pollutant at a rate equal to or greater than the minimum emission rate listed for that pollutant in LAC 33:III.5112, Table 51.1, shall control emissions of that toxic air pollutant to a degree that constitutes Maximum Achievable Control Technology (MACT) as approved by the administrative authority.

2. MACT determinations for sources not regulated by a federal MACT standard shall be determined by the administrative authority through the permitting process using the existing state MACT determination method or protocol.

B. Ambient Air Standard Requirements. The owner or operator of any major source that emits, or is permitted to emit, any toxic air pollutant at a rate equal to or greater than the minimum emission rate listed for that toxic air pollutant shall determine the status of compliance, beyond the source's property line, with applicable ambient air standards listed in LAC 33:III.5112, Table 51.2 (see LAC 33:III.5105.A.2).

1. Ambient air standards shall not apply to roads, railroads, water bodies, or other areas where activities are transient in nature and long-term exposure to emissions is not reasonably anticipated.

2. Ambient air standards shall not apply to industrial properties adjacent to or impacted by emissions from a major source, provided the owner or operator of the major source demonstrates that worker protection standards enacted pursuant to the federal Occupational Safety and Health Act as permissible exposure limits will not be exceeded on the impacted property due to toxic air pollutant emissions from the major source.

3. New major sources shall demonstrate compliance with an ambient air standard in an application for a permit in accordance with LAC 33:III.5111.

4. The owner or operator shall achieve compliance with the ambient air standard unless the owner or operator demonstrates to the satisfaction of the administrative authority:

a. that compliance with an ambient air standard would be economically infeasible;

b. that the source's emissions could not reasonably be expected to pose a threat to public health or the environment; and

c. that the source's emissions would be controlled to a level that is maximum achievable control technology.

5. The administrative authority shall publish a public notice of and hold a public hearing on any preliminary determination to allow a source to exceed the ambient air standard for any toxic air pollutant listed in LAC 33:III.5112, Table 51.2. Within 90 days after the close of the public hearing on the preliminary determination, the administrative authority shall make a final determination, which is subject to review on a five-year basis or at any other time deemed appropriate by the administrative authority.

6. The administrative authority shall periodically, at least every 36 months, review and update the ambient air standards listed for each toxic air pollutant in LAC 33:III.5112, Table 51.2.

C. Standard Operating Procedure Requirements

1. The requirements of this Subsection do not apply to emissions of any of those pollutants listed in LAC 33:III.5112, Table 51.3.

2. The owner or operator of any new or existing source required to report emissions in accordance with LAC 33:III.5107.A shall develop a standard operating procedure (SOP) within 120 days after achieving or demonstrating compliance with the standards specified in this Chapter. The SOP shall detail all operating procedures or parameters established by the owner or operator to ensure that compliance with the applicable standards is maintained, and shall address, but not be limited to, operating procedures for any monitoring system in place, specifying procedures to ensure compliance with LAC 33:III.5113.C.5. A written copy of the SOP must be available on site or at an alternate approved location for inspection by the administrative authority. A copy of the SOP must be provided within 30 days upon request by the department.

D. Compliance Timing

1. The department may take appropriate enforcement action to address the failure by an existing major source to submit a Compliance Plan or Certification of Compliance, which submittal was required by Paragraph A.1 or 2, and Paragraph B.1 or 2, of this Section as promulgated in the Louisiana Register on December 20, 1991, at LR 17:1204, until December 20, 2007.

2. A new source shall be in compliance with the MACT regulations upon initial start-up of the source.
