Proposed Air Quality Permit 6866-SC – Dry Cleaner Source Category Permit

PUBLIC NOTICE

Proposed Air Quality Permit 6866-SC – Dry Cleaner Source Category Permit for all Area Source Perchloroethylene Dry Cleaners

Notice is hereby given that, pursuant to 40 C.F.R. Part 51.161, D.C. Official Code §2-505, and Title 20, §§ 200 and 210 of the District of Columbia Municipal Regulations (DCMR) the Air Quality Division (AQD) of the District Department of the Environment (DDOE), located at 1200 First Street NE, 5th Floor, Washington, DC, intends to issue a source category permit covering a subset of dry cleaning facilities in the District of Columbia.  This source category permit will be designated Permit No. 6866-SC.

This permit will cover only dry cleaners considered to be area sources of perchlorothylene (also known as tetrachloroethylene or perc) in the District of Columbia.  This means that the covered sources will each emit less than 10 tons per year of perchloroethylene.  This equates to usage of less than 2,100 gallons per year of this solvent in the permissible types of dry cleaning machines.

This source category permit does not cover major source dry cleaning establishments emitting more than 10 tons per year of perchloroethylene (those purchasing greater than 2,100 gallons of perchloroethylene yearly). Additionally, this source category permit covers only the equipment at the facility using perchloroethylene as a dry cleaning solvent.  It does not cover other equipment regulated under 20 DCMR including boilers, generators and any other equipment at the facility capable of emitting air pollutants.  If any entity owns, operates, or plans to install any equipment of this sort, they should consult with AQD to determine the applicability of any other permitting requirements pursuant to 20 DCMR 200.

The proposed emission limits are as follows:

a.   Visible emissions shall not be emitted into the outdoor atmosphere from this equipment. [20 DCMR 201 and 606.1]

b.   An emission into the atmosphere of odorous or other air pollutants from any source in any quantity and of any characteristic, and duration which is, or is likely to be injurious to the public health or welfare, or which interferes with the reasonable enjoyment of life or property is prohibited. [20 DCMR 903.1]

c.   Emissions of perchloroethylene shall not exceed 10 tons in any given 12 month rolling period from any facility covered by this permit.

The draft permit and supporting documentation are available for public inspection at AQD and copies may be made available between the hours of 8:15 A.M. and 4:45 P.M. Monday through Friday.  Interested parties wishing to view these documents should provide their names, addresses, telephone numbers and affiliation, if any, to Stephen S. Ours at (202) 535-1747.

Interested persons may submit written comments or may request a public hearing on this subject within 30 days of publication of this notice.  The written comments must also include the person’s name, telephone number, affiliation, if any, mailing address and a statement outlining the air quality issues in dispute and any facts underscoring those air quality issues.  All relevant comments will be considered in issuing the final permit.

Comments on the proposed permit and any request for a public hearing should be addressed to:
