                   TITLE 40--PROTECTION OF ENVIRONMENT
 
         CHAPTER I--ENVIRONMENTAL PROTECTION AGENCY (CONTINUED)
 
PART 63--NATIONAL EMISSION STANDARDS FOR HAZARDOUS AIR POLLUTANTS FOR SOURCE CATEGORIES--Table of Contents
 
    Subpart D--Regulations Governing Compliance Extensions for Early 
                 Reductions of Hazardous Air Pollutants
 
Sec. 63.79  Approval of applications.

    (a) If an early reduction demonstration is approved and other 
requirements for a complete permit application are met, the permitting 
authority shall establish by a permit issued pursuant to title V of the 
Act enforceable alternative emissions limitations for the source 
reflecting the reduction which qualified the source for the extension. 
However, if it is not feasible to prescribe a numerical emissions 
limitation for one or more emission points in the source, the permitting 
authority shall establish such other requirements, reflecting the 
reduction which qualified the source for an extension, in order to 
assure the source achieves the 90 percent or 95 percent reduction, as 
applicable.
    (b) An alternative emissions limitation or other requirement 
prescribed pursuant to paragraph (a) of this section shall be effective 
and enforceable immediately upon issuance of the permit for the source 
and shall expire exactly six years after the compliance date of an 
otherwise applicable standard issued pursuant to section 112(d) of the 
Act.
