Air Quality Program Amends a General Order of Approval

In 2005, ecology created the legal framework for general orders of approval. Ecology's air quality program is now amending the automobile body repair and refinishing shops general order. The amended general order incorporates the new federal MACT Standard (Paint Stripping and Miscellaneous Surface Coating Operations at Area Sources (40 C.F.R. Part 63 Subpart HHHHHH)) as it applies to automobile body repair and refinishing shops. If a business wishes to install the equipment needed to run a body repair and refinishing shop, an application can be made for coverage under the general order, or the business can choose to go through the older more site specific notice of construction order of approval. The choice is made by the applicant.

Applicability Criteria for this General Order of Approval

Criterion Limitation
Location in Washington Any jurisdiction within which new source review requirements are regulated by the department of ecology's air quality program. At the time of issuance of this general order, this includes: Adams, Asotin, Chelan, Columbia, Douglas, Ferry, Franklin, Garfield, Grant, Kittitas, Klickitat, Lincoln, Okanogan, Pend Oreille, San Juan, Stevens, Walla Walla, and Whitman counties.
Facility description Repair and refinish the passenger and cargo enclosure (i.e., the "body") sections of automobiles, trucks, and other mobile equipment.
The spray booth is not part of a new major stationary source or major modification to a major stationary source (i.e., the spray booth is not subject to review under the prevention of significant deterioration program). The addition of the spray booth to an existing source does not make the source subject to the air operating permit (AOP) program or require a modification in an existing AOP permit.
Size Shall not use more than 950 gallons in any consecutive twelve months of refinishing materials of all types. This includes reducers and cleaning solvents.
Design Spray booth with at least an exhaust fan, filter (arrestor), and unrestricted exhaust stack. Exhaust fan, filter (arrestor), and exhaust stack sizes shall comply with the relationship described in this order.
If the spray booth or booths are combustion-heated independently from general shop heating:

(1) Only natural gas, propane, liquefied petroleum gas (LPG), or on-road quality diesel fuel may be used.

(2) The total heating capacity of the related combustion device(s) must be smaller than the following:

(a) four million Btu/hr for natural gas, propane, and LPG; and

(b) 1,000,000 Btu/hr for on-road quality diesel.

Refinishing materials Low-VOC: Compliant with 40 C.F.R. Part 59, Subpart B.

None may contain cadmium.

Equipment Spray gun transfer efficiency rating not less than typical of high volume, low pressure (HVLP) equipment.
Spray gun cleanup in closed system.

The draft order and fact sheet are available for review and public comment from March 19, 2008, to April 18, 2008. The public is encouraged to give written comments during the public comment period.

A general order is used instead of a series of individual notice of construction orders of approval when the permitted facilities are similar. Individual facilities that receive coverage under the general order are required to comply with the terms and conditions of the order.

This order will be available to applicants in the counties that are regulated directly by ecology's air quality program. These counties are: San Juan, Okanogan, Chelan, Douglas, Ferry, Stevens, Pend Oreille, Kittitas, Walla Walla, Columbia, Garfield, Asotin, Grant, Lincoln, Adams, Whitman, Franklin, and Klickitat counties. Applicants in other areas are regulated by a local air agency and are subject to their notice of construction rules and procedures. This order is also available to those sources of statewide importance that are directly regulated by ecology.

Issuing the Final Automobile Body Repair and Refinishing Shops General Order: Ecology will issue the final order after it considers all public comments. Ecology expects to issue the general order soon after the end of the public comment period. It will be effective thirty days later. When ecology issues the order, it will send a response to everyone who commented.

Who would be covered by the order? The order covers all new automobile body repair and refinishing shops who propose to emit air pollutants to [the] environment. The choice of whether to be covered by a more traditional individual notice of approval or this general order remains with the applicant.
