UTILITIES AND TRANSPORTATION

COMMISSION

[Filed January 28, 2026, 2:06 p.m.]

Subject of Possible Rule Making: Amending chapter 480-108 WAC to standardize processes for utilities to test and approve meter socket adapters (MSA).

Statutes Authorizing the Agency to Adopt Rules on this Subject: RCW 80.01.040 and 80.04.160.

Reasons Why Rules on this Subject may be Needed and What They Might Accomplish: The utilities and transportation commission (UTC) received a petition from ConnectDER, an MSA manufacturer, requesting UTC adopt an MSA approval process for investor-owned utilities that establishes clear timelines, clear and consistent minimum safety standards, and defined roles and responsibilities for MSA manufacturers and utilities.

Other Federal and State Agencies that Regulate this Subject and the Process Coordinating the Rule with These Agencies: Not applicable.

Process for Developing New Rule: UTC will request public comment on the CR-101, may issue additional notices for comment, and/or hold public workshops. If UTC determines amended rules are necessary and in the public interest, additional comments on the proposed draft rules will be requested prior to finalizing the proposed rule in the CR-102 phase.

Interested parties can participate in the decision to adopt the new rule and formulation of the proposed rule before publication by contacting Jeff Killip, Executive Director and Secretary, 621 Woodland Square Loop, Lacey, WA 98503, phone 360-664-1173, fax 360-586-1150, TTY 1-800-833-6384 or 711, email records@utc.wa.gov, website www.utc.wa.gov/e-filing.
