Bridge & Ferry Terminal Maintenance Permit
Washington’s bridge and ferry terminals need regular upkeep, including inspections, washing, painting, and surface repairs to keep them safe. When workers clean or perform maintenance on these structures, wastewater is created and can flow directly into surrounding water. The Bridge and Ferry Terminal Maintenance General Permit directs how that wastewater is managed to protect water quality while supporting the inspection and maintenance of bridges — and protecting the safety of Washington commuters.
About 10 entities are covered under this permit, ranging from single-site operations to large, multi-bridge programs, with WSDOT as our largest with more than 500 bridge and ferry terminal sites. The permit can also apply to local government and municipalities, as well as contractors who are working on their behalf.
The current permit went into effect July 17, 2026, and will expire July 16, 2031.

2026 permit reissuance
The previous permit was issued June 29, 2022, and was revoked when the new permit took effect: July 17, 2026. The official draft was released Dec. 3, 2025, which marked the beginning of a formal public comment period through Feb. 6, 2026. We held two online public meetings and formal hearings on Jan. 6 and 7, 2026, to explain the proposed changes to the permit, answer questions, and provide opportunity for formal spoken testimony on the draft permit. Appendix E of the fact sheet shows our response to comments received. You can read more about the reissuance in Ecology's December 2026 blog: Bridges over clean water: updating Ecology’s permit for bridge maintenance.
