Washington Air Quality Permit - Notice of Construction Permit (15-WA-a)
Air Quality Permit - Notice of Construction Permit Process
15-WA-a.1 to 15-WA-a.2 – Does the Project Require an Air Quality Construction Permit?
The developer will be required to obtain a Notice of Construction (NOC) air quality permit to construct or modify any building, structure, facility, or installation that:
- Increases, or may increase, the amount of any air contaminant emitted by such source; or
- Results in the emission of any air contaminant not previously emitted.
15-WA-a.3 – Is the Project Categorically Exempt?
Construction of a new emissions unit that has a potential to emit less than each of the levels listed in WAC 173-400-110(5) is exempt from new source review.
15-WA-a.4 to 15-WA-a.5 – Does the Project Require an Air Operating Permit?
If the project requires both an Air Operating Permit and an Air Quality Construction Permit, then the developer may enter a consolidated permitting process using the requirements for an Air Operating Permit. WAC 173-400-111(2).
An Air Operating Permit is required if a facility has the potential to emit any of the following:
- More than 100 tons per year of any pollutant;
- More than 10 tons per year of any hazardous air pollutant; or
- More than 25 tons per year of a combination of hazardous air pollutants.
15-WA-a.6 – Conduct Pre-Application Consultation, if Requested
The developer may choose to request a pre-application consultation with the WSDE to go over the application procedure and requirements.
15-WA-a.7 – Notice of Construction Application
The DECY is required to post a notice of the application on their website for a minimum of fifteen consecutive days. The internet posting must include a notice of the receipt of application, the type of proposed action, and a statement that the public may request a public comment period on the proposed action. WAC 173-400-171(2).
15-WA-a.8 – Review Application for Completeness
The DECY will examine the application materials to ensure that all necessary components are included.
15-WA-a.9 to 15-WA-a.10 – Is the Application Complete?
A complete application contains all the information necessary for processing the application. The developer, at a minimum, must provide:
- Information on the nature and amount of emissions to be emitted by the proposed new source or increased as part of a modification; and
- The location, design, construction, and operation of the new source as needed to enable the permitting authority to determine that the construction or modification meets requirements. WAC 173-400-111(1)(b).
15-WA-a.11 – Provide Notice of Completeness of Application
Within 30 days after receiving a notice of construction application, the WSDE must either notify the developer in writing that the application is complete or notify the developer in writing of all additional information necessary to complete the application. WAC 173-400-111(1)(a).
15-WA-a.12 – Is a Public Comment Period Required?
The WSDE must provide public notice and a public comment period before approving or denying the following types of applications or other actions:
- Any application, order, or proposed action for which a public comment period is requested in compliance with the internet posting requirement;
- Any notice of construction application for a new or modified source, including the initial application for operation of a portable source, if there is an increase in emissions of any air pollutant at a rate above the emission threshold rate or any increase in emissions of a toxic air pollutant above the acceptable source impact level for that toxic air pollutant as regulated under WAC 173-460;
- Any use of a modified or substituted air quality model, other than a guideline model in Appendix W of 40 CFR Part 51 as part of review under WAC 173-400-110, WAC 173-400-113, or WAC 173-400-117;
- Any order to determine reasonably available control technology, RACT;
- An order to establish a compliance schedule issued under WAC 173-400-161, or a variance issued under WAC 173-400-180;
- An order to demonstrate to creditable height of a stack which exceeds the good engineering practice, GEP, formula height and sixty-five meters, by means of a fluid model or a field study, for the purposes of establishing an emission limitation;
- An order to authorize a bubble;
- Any action to discount the value of an emission reduction credit, ERC, issued to a source per WAC 173-400-136;
- Any regulatory order to establish best available retrofit technology, BART, for existing stationary facility;
- Any notice of construction application or regulatory order used to establish a creditable emission reduction;
- Any order issued under WAC 173-400-091 that establishes limitations on a source’s potential to emit;
- The original issuance and the issuance of all revisions to a general order of approval issued under WAC 173-400-560;
- Any extension of the deadline to begin actual construction of a “major stationary source” or “major modification” in a nonattainment area; or
- Any application or other action for which the WSDE determines that there is a significant public interest.
