Notice of Intent Permits

Notice of Intent (NOI) permits are required for portable stationary sources installed and operated at a specific site temporarily (not to exceed 12-consecutive months) and then expected to be relocated to another site temporarily. Common portable stationary sources include rock crushers, asphalt plants, and concrete batch plants. The first time a portable source operates in Spokane County, a Notice of Construction (NOC) permit is required. If a portable source has operated in Spokane County previously, an NOI permit is required prior to operation.

Spokane Clean Air maintains lists of NOC and NOI applications received for public review and comment.

Applying for an NOI Permit

Permit application forms are available for specific types of operations and for others, a generic application should be used. The completed form and accompanying information, along with the base fee, and the SEPA Checklist (if required) must to mailed or hand-delivered to Spokane Clean Air. What is SEPA?

Application Review

Once Spokane Clean Air receives an NOI application and accompanying information, a 15-day public notice is posted on the agency’s webpage, and staff reviews the project to ensure that all applicable local, state and federal air pollution regulations are addressed. A final NOI permit with approval conditions is issued along with an invoice for additional review fees. The entire process typically takes 15-30 days after receipt of a complete application package.

Ways to keep costs down on NOC/NOI reviews:

Submit a complete NOC/NOI application with all of the requested information, including manufacturer information and SDS sheets, if required
Submit a site plan that shows the location of the proposed equipment in relation to the building(s) on the property and the distance from the stack(s) to the nearest property line
Finalize the project and/or equipment design prior to submitting the NOC/NOI application to minimize changes during the permit review process
Check with other government agencies (e.g., fire dept) prior to submitting NOC/NOI application to ensure all other requirements have been met
Ensure requirements of SEPA have already been met for the project location or submit an Environmental Checklist to SRCAA as part of the NOC / NOI application
As a general rule, NOC / NOI applications submitted for used equipment and/or equipment that has already been installed takes significantly more time to review and process than applications submitted for new equipment that has not yet been installed.

SRCAA offers free business assistance services and is available to review a project or draft NOC/NOI application prior to submittal. Contact SRCAA prior to the submittal of an NOC/NOI application to schedule a meeting to review your project.
