1. (a) Vent the entire dryer exhaust through a properly functioning carbon adsorption system or equally effective control device;
2. (b) Operate the device required by paragraph (a) of this subsection so that it provides a ninety percent (90%) reduction in volatile organic compound emissions or so that it emits no more than one-hundred parts per million (100 ppm) of volatile organic compound from the dryer control device before dilution;
3. (c) Immediately repair all components found to be leaking liquid volatile organic compounds;
4. (d) Cook or treat all diatomaceous earth filters so that the residue contains twenty-five (25) pounds or less of volatile organic compounds per one hundred (100) pounds of wet waste material;
5. (e) Reduce the volatile organic compounds from all solvent stills to sixty (60) pounds or less per one hundred (100) pounds of wet waste material;
6. (f) Drain all filtration cartridges, in the filter housing, for at least twenty-four (24) hours before discarding the cartridges; and
7. (g) When possible, dry all drained cartridges without emitting volatile organic compounds to the atmosphere.

707.2 The provisions of §§ 707.1(a) and (b) are not applicable to the following:

1. (a) Perchloroethylene dry cleaning facilities which are coin operated;
2. (b) Facilities where an adsorber cannot be accommodated because of inadequate space; or
3. (c) Facilities with insufficient steam capacity to desorb the adsorbers.

707.3 The Mayor may exclude other facilities if it is demonstrated that other hardships justify an exclusion.

707.4 The owner or operator of a perchloroethylene dry cleaning facility subject to § 707.1(a) or (b) which is in existence on the effective date of the District of Columbia Air Pollution Control Act of 1984 shall meet the applicable increments of progress in the following schedule:

1. (a) Submit final emission control plans to the Mayor no later than March 1, 1986;
2. (b) Award contracts, issue purchase orders, or otherwise order the emission control system and process equipment no later than June 1, 1986;
3. (c) Complete installation of the emission control and process equipment, no later than May 1, 1987; and
4. (d) Achieve final compliance, determined in accordance with this section no later than June 1, 1987.

707.5 The owner or operator of a perchloroethylene dry cleaning facility subject to this section shall comply with the operational and maintenance provisions of §§ 707.1(c) through (g) by June 1, 1986.707.6 The owner or operator of a perchloroethylene dry cleaning facility subject to this subtitle may submit to the Mayor, and the Mayor may approve, a proposed alternative compliance schedule; Provided, that the following occurs:- (a) The proposed alternative compliance schedule is submitted before January 15, 1986;

- (b) The owner or operator provides information showing the need for an alternative schedule;

- (c) The alternative compliance schedule contains increments of progress;

- (d) Sufficient documentation and certification from appropriate suppliers, contractors, manufacturers, or fabricators is submitted by the owner or operator of the subject facility to justify the dates proposed for the increments of progress; and

- (e) Final compliance is achieved as expeditiously as possible prior to December 31, 1987.707.7 Compliance with §§ 707.1(a), (f), and (g) shall be determined by means of a visual inspection.707.8 Compliance with § 707.1(c) shall be determined by means of a visual inspection of the following components:- (a) Hose connections, unions, couplings, and valves;

- (b) Machine door gaskets and seatings;

- (c) Filter head gasket and seating;

- (d) Pumps;

- (e) Base tanks and storage containers;

- (f) Water separators;

- (g) Filter sludge recovery;

- (h) Distillation unit;

- (i) Diverter valves;

- (j) Saturated lint from lint basket; and

- (k) Cartridge filters.707.9 Compliance with § 707.1(b) shall be determined by the following:- (a) A test consistent with EPA Guideline Series document, 'Measurement of Volatile Organic Compounds,' EPA-450/2-78-041; or

- (b) The proper installation, operation, and maintenance of equipment which has been

demonstrated to be adequate to meet the emission limits in § 707.1(b).

707.10 Compliance with §§ 707.1(d) and (e) shall be determined by means of the procedure in the American National Standards Institute paper, 'Standard Method of Test for Dilution of Gasoline Engine Crankcase Oils.'
