EXPEDITED RULES
TRANSPORTATION COMMISSION
[Filed March 18, 2025, 3:08 p.m.]
Title of Rule and Other Identifying Information: SR 99 Tunnel planned three percent toll rate increase (WAC 468-270-073).
Purpose of the Proposal and Its Anticipated Effects, Including Any Changes in Existing Rules: This proposal implements the planned three percent toll rate increase for the SR 99 Tunnel that will take effect on July 1, 2025, as established in WAC 468-270-073 and as described in WAC 468-270-040 in October 2018.
Reasons Supporting Proposal: When toll rates were initially set on the SR 99 Tunnel in October 2018, the Washington state transportation commission (WSTC) established a plan for three percent toll rate increases to take effect every three years, subject to review and approval by WSTC. The purpose of these planned toll rate increases is to manage ongoing cost inflation and support financial sufficiency for the facility. As such, this rule provides transparency and further clarification for the public regarding toll rate amounts currently established in chapter 468-270 WAC for the SR 99 Tunnel.
Statutory Authority for Adoption: RCW 47.56.030, 47.56.850, and 47.56.862.
Statute Being Implemented: RCW 47.56.830 and 47.56.862.
Rule is not necessitated by federal law, federal or state court decision.
Name of Proponent: WSTC, governmental.
Name of Agency Personnel Responsible for Drafting: Carl See, WSTC, 2404 Chandler Court S.W., Olympia, WA 98504, 360-705-7070; Implementation and Enforcement: Ed Barry, Washington state department of transportation, 2901 Third Avenue, Suite 500, Seattle, WA 98121, 206-464-1217.
This notice meets the following criteria to use the expedited adoption process for these rules:
Have been the subject of negotiated rule making, pilot rule making, or some other process that involved substantial participation by interested parties before the development of the proposed rule.
Explanation of the Reason the Agency Believes the Expedited Rule-Making Process is Appropriate: This rule making will change toll rates on the SR 99 Tunnel consistent with the intent of WAC 468-270-040 (3)(b), and as such expedited rule making is appropriate. The plan for a three percent toll rate increase for the SR 99 Tunnel on July 1, 2025, was established in WAC 468-270-073 and described in WAC 468-270-040 (3)(b), as adopted by WSTC in October 2018 with public notice and comments taken at that time.
NOTICE
THIS RULE IS BEING PROPOSED UNDER AN EXPEDITED RULE-MAKING PROCESS THAT WILL ELIMINATE THE NEED FOR THE AGENCY TO HOLD PUBLIC HEARINGS, PREPARE A SMALL BUSINESS ECONOMIC IMPACT STATEMENT, OR PROVIDE RESPONSES TO THE CRITERIA FOR A SIGNIFICANT LEGISLATIVE RULE. IF YOU OBJECT TO THIS USE OF THE EXPEDITED RULE-MAKING PROCESS, YOU MUST EXPRESS YOUR OBJECTIONS IN WRITING AND THEY MUST BE SENT TO Carl See, WSTC, P.O. Box 47308, Olympia, WA 98504-7308, phone 360-705-7070, fax 360-705-6802, BEGINNING April 2, 2025, 12:00 a.m., AND RECEIVED BY May 19, 2025, 11:59 p.m.
