Climate Commitment Act Program, Chapter 173-446 WAC

Proposed rulemaking – Public comment period EXTENDED

May 16, 2022 - July 15, 2022, 11:59 p.m.

Public comment period is EXTENDED through July 15, 2022 (originally June 30, 2022).

Ecology is proposing a new rule, Chapter 173-446 WAC, Climate Commitment Act Program.  The Climate Commitment Act requires Ecology to adopt rules to implement the cap-and-invest program to achieve Washington's goal of net zero greenhouse gas emissions by 2050.

This rulemaking establishes a structure for the cap-and-invest program including, but not limited to:

  • Program coverage, registration, and account requirements
  • Methods and procedures for allocating allowances
  • Allowance budgets for the first compliance period (2023–2026) and distribution of allowances
  • Auction registration requirements
  • Auction floor price
  • Auction floor and ceiling prices, and Tier I and Tier II prices for allowance price containment reserve auctions
  • Emissions containment reserve
  • Procedures and protocols for offset projects
  • Enforcement provisions
  • Transfer and sale of allowances and recognition of compliance instruments
  • Other elements to support the operation and function of the cap-and-invest program
     

Background

We write rules to implement and enforce state and federal environmental laws and rules.  Ecology follows a 3-phase process for rulemaking:

  1. Announcement and development
  2. Proposal
  3. Adoption

For each phase of the process, we update the rulemaking web page and notify interested parties. We also file notice in the Washington State Register. To learn more about Ecology’s rulemaking process, read the Frequently Asked Questions.
