Application Fee and Other Clarifying Updates Rulemaking Proposal - Chapters 173-455, 173-400, 173-50 WAC

Ecology is proposing amendments for the following air quality rules: WAC 173-455-120 WAC, New source review and other air permitting fees and WAC 173-400-111 WAC, Processing notice of construction applications for sources, stationary sources, and portable sources. These amendments relate to two air quality permits and six air quality general orders.


The proposed rule amendments make technical changes to the rules that will allow us to proceed with requirements under the EO; specific proposed amendments include: 

  • Clarifying the definition of "application fee.” 
  • Clarifying that any fee refunds cannot exceed the amount of the application fee that was originally paid. 
  • Clarifying that Ecology will not charge additional fees to recover the costs of a refund. 
  • Removing outdated fee language in WAC 173-455-120. 
  • Removing language about the rescinded general order of approval for dairy anaerobic digesters in WAC 173-455-120. 

 

Ecology is also proposing an amendment to WAC 173-50-190, Fee structure, which provides the fee structure for environmental laboratory accreditation program. This amendment removes language prohibiting refunds for application fees. 


This is the first filing for this rule, as it is exempt from filing a CR-101 rule announcement under RCW 34.05.310. We expect to adopt the rule amendments on August 11, 2026.
