By December 1, 1999, the department and the department of health shall jointly establish a formal agreement that identifies the roles of each of the two agencies with respect to the enforcement of temporary worker housing operation standards.

The agreement shall, to the extent feasible, provide for inspection and enforcement actions by a single agency, and shall include measures to avoid multiple citations for the same violation.

For the purposes of this section, "temporary worker housing" has the same meaning as provided in RCW 70.114A.020.
