| Final water quality permit – City of Spokane Wastewater Treatment Ecology has finalized the permit for City of Spokane Wastewater Treatment Facility (WA0024473). This is the final of five permits we have issued to ensure the wastewater treatment facilities that discharge into the Spokane River continue to meet clean water requirements. Previously, we held a public comment period on the draft permit from Dec. 29, 2021 – Feb. 1, 2022 and May 11 – June 11, 2022. We’ve included a response to comments we received as an appendix to the permit.

Public comment period
Draft Spokane Water Quality Permit
We previously held a public comment period from Dec. 29, 2021 to Feb. 1 2022, on the City of Spokane proposed draft permit and fact sheet. After reviewing the comments, we made several changes to the permit and fact sheet in response to comments. As a result, we are providing an additional opportunity to review and comment on the proposed permit before we make a final decision. Please review and comment on the draft permit until 11:59 p.m. June 10, 2022.
In addition to correcting technical and typographical errors, we also changed the permit and explanatory language in the fact sheet for the following topics:
• Effluent limits; Section S1
• Mixing Zone for PCBs; Section S1.A, Table 2
• Mixing Zone flows; Section S1.B, Table 5
• Effluent monitoring for PCBs and other parameters; Section S2; Table 7
• Design limits for Next Level Treatment; Section S4
• Exfiltration testing; Section S5.H
• CSO Post Construction Monitoring Plan; Section S14.C.c
• Spokane River Regional Toxics Task Force; Section S17.B
• Compliance schedules for pH and PCBs: Section S18
• Reopener clause; Section G3

Next Steps
After reviewing the feedback we receive, we respond to comments and will make decisions on permit reissuance for the facility. We plan to complete this work by Summer 2022.
