PART 63--NATIONAL EMISSION STANDARDS FOR HAZARDOUS AIR POLLUTANTS FOR SOURCE CATEGORIES--Table of Contents
 
Subpart B--Requirements for Control Technology Determinations for Major 
 Sources in Accordance With Clean Air Act Sections, Sections 112(g) and 
                                 112(j)
 
Sec. 63.56  Requirements for case-by-case determination of equivalent emission limitations after promulgation of subsequent MACT standard.

    (a) If the Administrator promulgates a relevant emission standard 
that is applicable to one or more affected sources within a major source 
before the date a permit application under this paragraph (a) is 
approved, the title V permit must contain the promulgated standard 
rather than the emission limitation determined under Sec. 63.52, and the 
owner or operator must comply with the promulgated standard by the 
compliance date in the promulgated standard.
    (b) If the Administrator promulgates a relevant emission standard 
under section 112(d) or (h) of the Act that is applicable to a source 
after the date a permit is issued pursuant to Sec. 63.52 or Sec. 63.54, 
the permitting authority must incorporate requirements of that standard 
in the title V permit upon its next renewal. The permitting authority 
must establish a compliance date in the revised permit that assures that 
the owner or operator must comply with the promulgated standard within

[[Page 87]]

a reasonable time, but not longer than 8 years after such standard is 
promulgated or 8 years after the date by which the owner or operator was 
first required to comply with the emission limitation established by the 
permit, whichever is earlier. However, in no event shall the period for 
compliance for existing sources be shorter than that provided for 
existing sources in the promulgated standard.
    (c) Notwithstanding the requirements of paragraph (a) or (b) of this 
section, the requirements of paragraphs (c)(1) and (2) of this section 
shall apply.
    (1) If the Administrator promulgates an emission standard under 
section 112(d) or (h) that is applicable to an affected source after the 
date a permit application under this paragraph is approved under 
Sec. 63.52 or Sec. 63.54, the permitting authority is not required to 
change the emission limitation in the permit to reflect the promulgated 
standard if the permitting authority determines that the level of 
control required by the emission limitation in the permit is 
substantially as effective as that required by the promulgated standard 
pursuant to Sec. 63.1(e).
    (2) If the Administrator promulgates an emission standard under 
section 112(d) or (h) of the Act that is applicable to an affected 
source after the date a permit application is approved under Sec. 63.52 
or Sec. 63.54, 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 permitting 
authority is not required to incorporate any less stringent emission 
limitation of the promulgated standard in the title V 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 title V permit.
