(1) The owner or operator of a vessel required to document financial responsibility under this chapter must:

(a) Obtain a Washington COFR; or

(b) Be verified by ecology to be a current member of a P&I club.

(2) The owner or operator of a facility required to demonstrate financial responsibility under this chapter must obtain a Washington COFR.

(3) An owner or operator of more than one vessel or facility that is required to obtain a Washington COFR under this chapter may obtain a single Washington COFR that applies to all of the owner's or operator's vessels and facilities. Ecology will base the terms of such Washington COFR upon the vessel or facility that represents the greatest financial risk in the event of a spill. Alternatively, the owner or operator may obtain separate Washington COFRs that each apply to a subset of the owner's or operator's vessels or facilities, provided that each vessel or facility of the owner or operator is covered by at least one valid Washington COFR.
