Chapter 173-446 WAC – Allowance Price Containment Reserve

On February 21, 2024, Ecology adopted a rule: Chapter 173‑446 WAC, Climate Commitment Act Program Rule. The purpose of this rule is to clarify two aspects of the Allowance Price Containment Reserve (APCR) auctions under the cap-and-invest program.

The rule clarifies that:

  • Existing holding limits specified in WAC 173-446-150(2)(a), that apply to allowances with a “vintage,” also apply to the “vintage less” allowances that are acquired through APCR auctions. "Vintage year" means the annual allowance allocation budget year to which an individual Washington greenhouse gas (GHG) allowance is assigned. Holding limits ensure that one entity can hold only a certain number of allowances in its account at a time.
  • Any allowances purchased in an APCR auction must be deposited directly into the entity’s compliance account. This change to WAC 173-446-370 prevents APCR allowances from being sold or traded on the secondary market, thereby ensuring that the allowances will be used to meet compliance obligations and not for trading purposes.

Ecology adopted three consecutive emergency rules while we were working on the permanent rule.

The APCR is a tool designed to assist in containing compliance costs for covered and opt-in entities (RCW 70A.65.150(2)). If, during a quarterly auction, the settlement price reaches a certain threshold (the APCR Tier I price, which is $51.90 for 2023), we hold a separate APCR auction. Only covered and opt-in entities can participate in an APCR auction. Adding the APCR allowances into the market helps make sure that covered and opt-in entities can obtain enough allowances at a reasonable price to meet their compliance obligations. Unlike other allowances, the allowances sold in an APCR auction do not have a “vintage,” so they can be used for compliance in any year or any compliance period.

Rule adoption documents:

Emergency rulemaking is a modified rulemaking process that allows us to immediately amend a rule if there is a statutory basis for doing so. In this case, we have identified that making the above changes to the APCR auction mechanism meets the statutory basis of being “necessary… for the general welfare” because the changes are needed in order to protect against manipulation of the allowance market, which could result in price distortions that would harm the public interest in the efficient operation of Washington’s carbon markets. An APCR auction can be triggered after any regular quarterly auction and these rule amendments are needed in advance of an APCR auction taking place.

Once filed, this emergency rule change goes into effect immediately. It stays in effect for up to 120 days and may be renewed. We have also announced a permanent rulemaking process with these changes.
