9 Va. Admin. Code § 5-60-180

Current through Register Vol. 41, No. 4, October 8, 2024

Section 9VAC5-60-180 - Requirements for case-by-case determination of equivalent emission limitations after promulgation of a subsequent MACT standard

A. If the administrator promulgates a MACT standard that is applicable to one or more affected source within a major source before the date a federal operating permit application under this subsection is approved, the permit will contain the promulgated standard rather than the emission limitation determined under 9VAC5-60-140, and 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 source after the date a federal operating permit is issued pursuant to 9VAC5-60-140 or 9VAC5-60-160, the board will incorporate requirements of that standard in the permit upon its next renewal. The board will establish a compliance date in the revised federal operating permit that assures that the owner shall comply with the promulgated standard within a reasonable time, but not longer than eight years after such standard is promulgated or eight years after the date by which the owner was first required to comply with the emission limitation established by the federal operating permit, whichever is earlier. However, in no event will the period for compliance for existing sources be shorter than that provided for existing sources in the promulgated standard.

C. Notwithstanding the requirements of subsections A and B of this section, the requirements of subdivisions 1 and 2 of this subsection apply.

1. If the administrator promulgates a MACT standard under § 112(d) or (h) of the federal Clean Air Act that is applicable to an affected source after the date a federal operating permit application is approved under 9VAC5-60-140 or 9VAC5-60-160, the board is not required to change the emission limitation in the federal operating permit to reflect the promulgated standard if the board determines that the level of control required by the emission limitation in the federal operating permit is substantially as effective as that required by the promulgated standard pursuant to 40 CFR 63.1(e).

2. If the administrator promulgates an emission standard under § 112(d) or (h) of the federal Clean Air Act that is applicable to an affected source after the date a permit application is approved under 9VAC5-60-140 or 9VAC5-60-160, and the level of control required by the promulgated standard is less stringent than the level of control required by any emission limitation in the prior MACT determination, the board is not required to incorporate any less stringent emission limitation of the promulgated standard in the federal operating permit and may in its discretion consider any more stringent provisions of the MACT determination to be applicable legal requirements when issuing or revising such a federal operating permit.
