  7. 5.5.4.7 The dates and monitoring results for carbon adsorbers, as specified in 5.4 of this regulation, if a carbon adsorber is used to comply with 5.3.1.1, 5.3.1.2, 5.3.2.1, 5.3.2.3, 5.3.8, or 5.3.15.5 of this regulation.
5. 5.5.5 Each owner or operator of a dry cleaning facility shall retain onsite a copy of the design specifications and the operating manuals for each dry cleaning system and each emission control device located at the dry cleaning facility.
6. 5.5.6 Each owner or operator of a dry cleaning facility shall submit to the Department by registered mail not later than July 28, 2008 or within 30 days of startup, whichever is later, a notification of compliance status providing the following information and signed by a responsible official who shall certify its accuracy:
  1. 5.5.6.1 The name and address of the owner or operator;
  2. 5.5.6.2 The address (that is, physical location) of the dry cleaning facility;
  3. 5.5.6.3 Whether or not the dry cleaning facility is located in a building with a residence, even if the residence is vacant at the time of this notification;
  4. 5.5.6.4 Whether or not the dry cleaning facility is located in a building with no other tenants, leased space, or owner occupants;
  5. 5.5.6.5 Whether or not the refrigeration system on each dry cleaning system located at the dry cleaning facility is equipped with high and low pressure gauges;
  6. 5.5.6.6 Whether or not a dry cleaning system has been newly installed, constructed or added at the dry cleaning facility since December 21, 2005;
  7. 5.5.6.7 All information necessary to demonstrate to the Department’s satisfaction that each vapor barrier enclosure used to meet the requirements in 5.3.15.5.2.1 of this regulation meets the requirements in 5.2 of this regulation;
  8. 5.5.6.8 Whether the dry cleaning facility is a major or area source;
  9. 5.5.6.9 The yearly perchloroethylene solvent consumption based upon the yearly solvent consumption calculated according to 5.4.4 of this regulation;
  10. 5.5.6.10 Whether or not the dry cleaning facility is in compliance with each applicable requirement in 5.3 of this regulation; and
  11. 5.5.6.11 All information contained in the statement is accurate and true.
5.6 Determination of equivalent emission control technology.
1. 5.6.1 Any person requesting that the use of certain equipment or procedures be considered equivalent to the requirements in 5.3 of this regulation shall collect, verify, and submit to the Administrator (with copy to the Department) the following information to show that the alternative achieves equivalent emission reductions:
  1. 5.6.1.1 Diagrams, as appropriate, illustrating the emission control technology, its operation, and integration into or function with dry-to-dry machines or transfer machine systems and their ancillary equipment during each portion of the normal dry cleaning cycle;
  2. 5.6.1.2 Information quantifying vented perchloroethylene emissions from the dry-to-dry machines or transfer machine systems during each portion of the dry cleaning cycle with and without the use of the candidate emission control technology;
  3. 5.6.1.3 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 one 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. 5.6.1.4 Identification of maintenance requirements and parameters to monitor to ensure proper operation and maintenance of the candidate emission control technology;
  5. 5.6.1.5 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. 5.6.1.6 Explanation of why this information can or cannot be extrapolated to dry cleaning systems other than the specific systems examined; and
  7. 5.6.1.7 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.
2. 5.6.2 For the purpose of determining equivalency to control equipment required in 5.3 of this regulation, the Administrator will evaluate the petition to determine whether equivalent control of perchloroethylene emissions has been adequately demonstrated.
3. 5.6.3 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.
