We held a public comment period for the facility’s renewal of their AOP, along with the addition of an Acid Rain permit. The comment period was held from October 6 to November 5, 2025, and received three comments, all of which were in opposition to the renewal. The AOP is subject to a 45-day review by the Environmental Protection Agency prior to being approved by the Council.

We held a public comment period for the facility’s renewal of their NPDES permit. The comment period was held from September 29 to October 28, 2025, and received no comments. The Council approved the NPDES permit at the November 2025 Council meeting.

Prior permitting action included, Council approval and issuance of a five-year Title V Air Operating Permit effective July 17, 2024 and issuance of a fifth amendment to the Prevention of Significant Deterioration (PSD) permit on January 28, 2021.

The Council has operational and monitoring oversight of the stormwater and wastewater treatment systems under the National Pollutant Discharge Elimination System (NPDES), the Title V Air Operating Permit (AOP), and the Prevention of Significant Deterioration (PSD) permit.

State regulations require monitoring the operation of the facilities to determine compliance with the terms of the SCA. For regulatory details, please see Chapters 463-70 WAC, 463-72 WAC, 463-76 WAC, and 463-78 WAC.  

The Site Certification Agreement (SCA) requires the certificate holder to create site restoration plans and have them on file. The holder will need to submit a final site restoration plan when they plan to decommission the facility.

State regulations set deadlines for submitting both an initial and a detailed site restoration plan. The regulations also list the required elements that must be included in those plans to secure Council approval. For regulatory details, please see Chapter 463-72 WAC.
