Rule Making

Chapter 173-441 WAC
Reporting of Emissions of Greenhouse Gases Rule

Overview of Rulemaking

Ecology adopted amendments to Chapter 173-441 WAC (Reporting of Emissions of Greenhouse Gases). As required by Washington law, this rule must remain consistent with EPA's Greenhouse Gas Reporting Program. The adopted amendments included:

  • Revising the Global Warming Potentials or GWPs (GWP is a relative measure of how much heat a greenhouse gas traps in the atmosphere)
  • Updating calculation and monitoring methods
  • Streamlining revisions to reporting requirements
  • Correcting minor errors and improving readability

Ecology did not change existing requirements for:

  • Transportation fuel suppliers
  • Facilities
    • Reporting threshold
    • Confidential business information
    • Fees

Process

Ecology’s process for developing a rule includes gathering input from affected stakeholders (person or business that has an interest or investment) and the public, and following the steps for rule adoption.
