NATIONAL EMISSION STANDARDS FOR HAZARDOUS AIR POLLUTANTS FROM PERCHLOROETHYLENE DRY CLEANING FACILITIES -- FINAL RULE -- FACT SHEET

BACKGROUND:

REQUIREMENTS OF EPA DRY CLEANERS RULE:

IMPACTS:

In 1996 about 25,000 commercial and industrial dry cleaning facilities will be in operation. Although the dry cleaning industry exhibits little growth, about 7,700 of these 25,000 facilities will be new facilities built to replace existing facilities that retire. Of these 7,700 new facilities, about 400 would likely be uncontrolled in the absence of the rule and, as a result of the rule, will be required to install process vent control. In addition, the EPA rule will require about 3,200 existing uncontrolled facilities to install controls on process vents.

The rule will result in a total maximum national emissions reduction of perchloroethylene of 6,600 megagrams (Mg) (7,300 tons) from process vent control and 25,800 Mg (28,400 tons) from leak detection and repair (LDAR) from projected 1996 emission levels.

Energy: Total maximum national increase in electricity use (needed to operate the control devices) of 0.28 gigawatt hours per year (GWh/yr) in 1996 for new facilities and 2.5 Gwh/yr for existing facilities.

Annualized Cost: Total national increase of $3.9 million/year for process vent control in 1996, if solvent savings are included. Total national increase of $9.0 million in 1996, if solvent savings are not included. Total national cost savings of $7.6 million for LDAR, if cost savings are included. Total national increase or $10.0, if solvent savings are not included.

Capital Cost: Total national increase of $3 million for new dry cleaning facilities and $32 million for existing dry cleaning facilities in 1996.

Perchloroethylene Emission Reductions: Individual reduction of 0.8 Mg/yr (0.9 tons per year) from process vent control and 0.8 Mg/yr (0.9 tons per year) from LDAR from projected 1996 emission levels.

Wastewater: Total maximum increase of 0.03 kilograms/yr (0.07 pounds per year) of PCE in wastewater in 1996.

Solid Waste: No increase for the typical facility.

Noise: No incremental impacts.

Energy: The increase in electricity use (needed to operate refrigerated condenser) of 604 kilowatt hours per year in 1996.

Annualized Cost: Increase of $1,100/year for process vent control and $460/year for LDAR, monitoring, reporting, and record keeping.

Capital Cost: Increase of $6,300/year in 1996.
