of a new major stationary source or
major modification to a major stationary
source which is subject to preview
under the prevention of significant
deterioration program. 2. The addition of the boiler or water heater to an existing source does not make the source subject to the air operating permit program or require a modification in an existing air operating permit. |

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.
Requesting Copies of the Order: You can request copies of the proposed order and fact sheet by contacting Tom Todd, Department of Ecology, P.O. Box 47600, Olympia, WA 98504-7600, phone (360) 407-7528, fax (360) 407-7534, e-mail ttod461@ecy.wa.gov.
The proposed order and fact sheet are also available online at http://www.ecy.wa.gov/programs/air/AOP_Permits/Boiler/GeneralOrders.htm under the concrete batch plant heading.
Submitting Written Comments: Ecology will accept written comments on the draft concrete batch plant general order and fact sheet. Comments should reference specific text when possible. Comments may address the following:
Technical issues,
Accuracy and completeness of information,
The scope of facilities proposed for coverage,
Adequacy of environmental protection and order conditions, or
Any other concern that would result from issuance of the revised order.
Please submit written comments to Tom Todd, Department of Ecology, P.O. Box 47600, Olympia, WA 98504-7600, phone (360) 407-7528, fax (360) 407-7534, e-mail ttod461@ecy.wa.gov.
Written, e-mailed and faxed comments must be received no later than 5 p.m., August 1, 2008.
Issuing the Final General Order of Approval for Small Water Heaters and Steam Generating Boilers: 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 concrete batch plants 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.
If you have special accommodation needs or require a copy of the order and fact sheet in an alternative format, please contact Tami Dahlgren, (360) 407-6830. If you are a person with a speech or hearing impairment, call 711 or 800-833-6388 for TTY.
