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?
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.
