(1) The department is responsible for requiring joint large-scale, multiple plan equipment deployment drills of covered vessels to determine the adequacy of the owner's or operator's compliance with the contingency plan requirements of this chapter. The department must order at least one drill as outlined in this section every three years, which must address situations where oils, depending on their qualities, weathering, environmental factors, and method of discharge, may submerge or sink in water.

(2) Drills required under this section must focus on, at a minimum, the following:

(a) The functional ability for multiple contingency plans to be simultaneously activated with the purpose of testing the ability for dedicated equipment and trained personnel cited in multiple contingency plans to be activated in a large scale spill; and

(b) The operational readiness during both the first six hours of a spill and, at the department's discretion, over multiple operational periods of response.

(3) Drills required under this section may be incorporated into other drill requirements under this chapter to avoid increasing the number of drills and equipment deployments otherwise required.

(4) Each successful drill conducted under this section may be considered by the department as a drill of the underlying contingency plan and credit may be awarded to the plan holder accordingly.

(5) The department shall, when practicable, coordinate with applicable federal agencies, the state of Oregon, and the province of British Columbia to establish a drill incident command and to help ensure that lessons learned from the drills are evaluated with the goal of improving the underlying contingency plans.
