PART 63_NATIONAL EMISSION STANDARDS FOR HAZARDOUS AIR POLLUTANTS
 
  Subpart M_National Perchloroethylene Air Emission Standards for Dry 
                           Cleaning Facilities
 
Sec.  63.325  Determination of equivalent emission control technology.

    (a) Any person requesting that the use of certain equipment or 
procedures be considered equivalent to the requirements under Sec.  
63.322 shall collect, verify, and submit to the Administrator the 
following information to show that the alternative achieves equivalent 
emission reductions:
    (1) Diagrams, as appropriate, illustrating the emission control 
technology, its operation and integration into or function with dry-to-
dry machine(s) or transfer machine system(s) and their ancillary 
equipment during each portion of the normal dry cleaning cycle;
    (2) Information quantifying vented perchloroethylene emissions from 
the dry-to-dry machine(s) or transfer machine system(s) during each 
portion of the dry cleaning cycle with and without the use of the 
candidate emission control technology;
    (3) Information on solvent mileage achieved with and without the 
candidate emission control technology. Solvent mileage is the average 
weight of articles cleaned per volume of perchloroethylene used. Solvent 
mileage data must be of continuous duration for at least 1 year under 
the conditions of a typical dry cleaning operation. This information on 
solvent mileage must be accompanied by information on the design, 
configuration, operation, and maintenance of the specific dry cleaning 
system from which the solvent mileage information was obtained;
    (4) Identification of maintenance requirements and parameters to 
monitor to ensure proper operation and maintenance of the candidate 
emission control technology;
    (5) Explanation of why this information is considered accurate and 
representative of both the short-term and the long-term performance of 
the candidate emission control technology on the specific dry cleaning 
system examined;
    (6) Explanation of why this information can or cannot be 
extrapolated to dry cleaning systems other than the specific system(s) 
examined; and
    (7) Information on the cross-media impacts (to water and solid 
waste) of

the candidate emission control technology and demonstration that the 
cross-media impacts are less than or equal to the cross-media impacts of 
a refrigerated condenser.
    (b) For the purpose of determining equivalency to control equipment 
required under Sec.  63.322, the Administrator will evaluate the 
petition to determine whether equivalent control of perchloroethylene 
emissions has been adequately demonstrated.
    (c) Where the Administrator determines that certain equipment and 
procedures may be equivalent, the Administrator will publish a notice in 
the Federal Register proposing to consider this equipment or these 
procedures as equivalent. After notice and opportunity for public 
hearing, the Administrator will publish the final determination of 
equivalency in the Federal Register.
