If any garbage and refuse collection company certified by the utilities and transportation commission which operates in any solid waste collection district fails to collect any fees due and payable to it for garbage and refuse collection services, such company may request the county to collect such fees. Upon the collection of such fees, the county shall pay one-half of the fees actually collected to the garbage and refuse collection company entitled to receive such and shall deposit the remaining one-half in the county general fund.

When the county undertakes to collect such fees as requested by the garbage and refuse collection companies, the county shall be subrogated to all of the rights of such companies. Any such fees which the county fails to collect shall become liens on the real or personal property of the persons owing such fees and the county may take all appropriate legal action to enforce such liens.

Certain provisions not to detract from commission powers, duties, and functions: RCW 80.01.300.
