(1) When a RFGPTS crosses state lines and is operating in Washington and a bordering state, the department will comply with the requirements set forth in 49 C.F.R. Part 674.15 for the designation of an oversight agency for a multistate system. The department will coordinate with the neighboring state SSOA and either ensure that both Washington's SSOA and the bordering state's SSOA are implementing uniform safety standards and requirements upon the RFGPTS (674.15a) or that a single SSOA is designated as the SSOA (674.15b).

(2) Where a bordering state agency is serving as the single entity SSOA, the bordering state's program standard and other safety standards and procedures will be used for oversight of the RFGPTS, unless otherwise stated through agreement or law. The Washington state rail safety oversight program standard will continue to apply to all other RFGPTS within Washington not subject to the special provisions of this section.

(3) An agreement will be established with the bordering state to set coordination of oversight duties and reporting for the RFGPTS subject to the program standard of a bordering state. The agreement must address the allocation of costs between the two states.
