Chapter 173-455 WAC

Ecology proposes to update Chapter 173-455 WAC, Air Quality Fee Rule which combines most of the air quality-related fees.  This rulemaking will update sections -038, -050, -100, -120, -130, and -140.  Other sections of this chapter may be added, to support these revisions, if necessary.

Ecology is proposing to update the permitting fee structure to:

  • Achieve full cost recovery for issuing permits.
  • Establish a process to revise future new source review (NSR) fees.

Specifically, this rulemaking will consider the following changes:

  • Update the hourly fee rate to reflect the new rate
    • Section -050 – Carbon dioxide mitigation fee
    • Section -100 – Fee related to reasonably available control technology (RACT)
    • Section -120 – New source review fee
    • Section -130 – Air pollution standards variance fee
    • Section -140 – Nonroad engine permit fee
  • Section -038 – Add greenhouse gas reporting fee, found in Chapter 173-441 WAC, Reporting of Emissions of Greenhouse Gases.
  • Section -100
    • Relocate fee established by RCW 70A.15.2220 for replacement or substantial alteration of control technology to the permit fee section to improve usability.
    • Evaluate whether a flat fee or an updated hourly rate is the appropriate fee for these reviews.
  • Update rule language to improve readability and clarity.
  • Update outdated references from Chapter 70.94 RCW to Chapter 70A.15 RCW.
