Wash. Rev. Code § 70A.200.090
The department shall design and the director shall adopt by rule or regulation one or more types of litter receptacles which are reasonably uniform as to size, shape, capacity and color, for wide and extensive distribution throughout the public places of this state. Each such litter receptacle shall bear an anti-litter symbol as designed and adopted by the department. In addition, all litter receptacles shall be designed to attract attention and to encourage the depositing of litter.
Litter receptacles of the uniform design shall be placed along the public highways of this state and at all parks, campgrounds, trailer parks, drive-in restaurants, gasoline service stations, tavern parking lots, shopping centers, grocery store parking lots, parking lots of major industrial firms, marinas, boat launching areas, boat moorage and fueling stations, public and private piers, beaches and bathing areas, and such other public places within this state as specified by rule or regulation of the director adopted pursuant to chapter 34.05 RCW. The number of such receptacles required to be placed as specified herein shall be determined by a formula related to the need for such receptacles.
It shall be the responsibility of any person owning or operating any establishment or public place in which litter receptacles of the uniform design are required by this section to procure and place such receptacles at their own expense on the premises in accord with rules and regulations adopted by the department.
Any person, other than a political subdivision, government agency, or municipality, who fails to place such litter receptacles on the premises in the numbers required by rule or regulation of the department, violating the provisions of this section or rules or regulations adopted thereunder shall be subject to a fine of ten dollars for each day of violation.
