Reasons Why Rules on this Subject may be Needed and What They Might Accomplish: Per RCW 47.56.870, the Washington state transportation commission (WSTC) as the state tolling authority must consider toll rates that will help maintain travel time, speed, and reliability on the SR 520 corridor, and must set and adjust toll rates and policies to generate revenue sufficient and necessary to cover costs and obligations described in RCW 47.56.830 and 47.56.850. Toll rates must also be set to meet requirements contained in the SR 520 master bond resolution. Per RCW 47.56.795, the WSTC is also authorized to assess system-wide administrative fees as appropriate for toll collection processes.

Other Federal and State Agencies that Regulate this Subject and the Process Coordinating the Rule with These Agencies: Other agencies that regulate this subject are the Washington state department of transportation as the operator of the tolled facilities, and the office of the state treasurer who oversees the financing of tolled facilities. The WSTC works closely, and coordinates with both agencies in developing toll setting proposals and carrying out the rule-making process for making toll adjustments.
