860.620 Applicability and designation of 

affected facility. 

(a) The provisions of this subpart 

are applicable to the following affected facilities located at a petroleum dry 

cleaning plant with a total manufacturers' rated dryer capacity equal to or 

greater than 38 kilograms (84 pounds): 

Petroleum solvent dry cleaning dryers, 

washers, filters, stills, and settling 

tanks. 

(1) When the affected faculty is installed ln an existing plant that is not 

expanding the manufacturers' rated 

capacity of Its petroleum solvent 

dryerts), the total manufacturers' 

rated dryer capacity is the summation 

of the manufacturers' rated capacity 

for each existing petroleum solvent 

dryer. 

(2) When the affected faculty Is installed ln a plant that is expanding the 

manufacturers' rated capacity of Its 

petroleum solvent dryers, the total 

manufacturers' rated dryer capacity is 

the summation of the manufacturers' 

rated dryer capacity for each existing 

and proposed new petroleum solvent 

dryer.

Environmental Protection Agency 

(3) When the affected facllty is inMailed in a new plant, the total manufacturers' rated dryer capacity is the 

summation of the manufacturers' 

rated dryer capacity for each proposed 

new petroleum solvent dryer. 

(4) The petroleum solvent dryers 

considered in the determination of the 

total manufacturers' rated dryer capacity are those new and existing 

dryers in the plant that will be ln service at any time after the proposed new 

source or modification commences operation. 

(b) Any facility under paragraph (a) 

of this section that commences construction or modification after December 14, 1982, is subject to the requirements of this subpart with the following exception. A dryer Installed between December 14,1982. and September 21, 1984. ln a plant with an annual 

solvent consumption level of less than 

4,700 gallons, is exempt from the requirements of this subpart.
