Virginia Administrative Code
Title 9. Environment
Agency 5. State Air Pollution Control Board
Chapter 80. Permits for Stationary Sources
12/22/2024

9VAC5-80-1590. Requirements for constructed or reconstructed major sources subject to a subsequently promulgated MACT standard or MACT requirements.

A. If the administrator promulgates a MACT standard under § 112(d) or § 112(h) of the federal Clean Air Act that is applicable to a stationary source, group of stationary sources, or portion of a stationary source which would be deemed to be a constructed or reconstructed major source under this article before the date the owner has obtained a final and legally effective permit pursuant to this article, the owner shall comply with the promulgated standard by the compliance date in the promulgated standard.

B. If the administrator promulgates a MACT standard under § 112(d) or § 112(h) of the federal Clean Air Act that is applicable to a stationary source, group of stationary sources, or portion of a stationary source which was deemed to be a constructed or reconstructed major source under this article and has been subject to a prior case-by-case MACT determination pursuant to this article, and the owner obtained a final and legally effective case-by-case MACT determination prior to the promulgation date of the MACT standard, the department shall (if the initial federal operating permit has not yet been issued) amend the permit issued pursuant to this article in accordance with the reopening procedures of 9VAC5-80-1580 to incorporate the emission standard, or shall (if the initial federal operating permit has been issued) revise the federal operating permit according to the reopening procedures in 9VAC5-80-240 to incorporate the MACT standard.

1. The MACT standard established pursuant to § 112(d) or § 112(h) of the federal Clean Air Act may specify a compliance date for those sources which have obtained a final and legally effective case-by-case MACT determination under this article. In that event, the department shall reopen the source's federal operating permit in accordance with the procedures in 9VAC5-80-240 to incorporate the applicable compliance date.

2. If no compliance date is specified in the MACT standard established pursuant to § 112(d) or § 112(h) of the federal Clean Air Act for those sources which have obtained a final and legally effective case-by-case MACT determination under this article, the department shall establish a compliance date that assures the owner will comply with a promulgated MACT standard as expeditiously as practicable, but no longer than eight years after the standard is promulgated, and shall reopen the source's federal operating permit in accordance with procedures in 9VAC5-80-240 to incorporate that compliance date.

C. Notwithstanding the requirements of subsections A and B of this section, if the administrator promulgates a MACT standard under § 112(d) or § 112(h) of the federal Clean Air Act that is applicable to a stationary source, group of stationary sources, or portion of a stationary source which was deemed to be a constructed or reconstructed major source under this article and which is the subject of a prior case-by-case MACT determination pursuant to this article, and the level of control required by the MACT standard issued under § 112(d) or § 112(h) is less stringent than the level of control required by any emission limitation or standard in the prior case-by-case MACT determination, the department is not required to incorporate any less stringent terms of the promulgated standard in the source's federal operating permit and may, in its discretion, consider any more stringent provisions of the prior case-by-case MACT determination to be applicable legal requirements when issuing or revising the federal operating permit.
