A can is empty when all contents have been completely sprayed out, and minimal or no product remains in the can.  Containers holding compressed gases are empty when the pressure inside the container is equal—or nearly equal—to atmospheric pressure. Aerosol cans that are not empty are not accepted from residents in large quantities (more than 10 cans) and are not accepted from businesses in any quantity. Pressurized containers from residential customers may also be taken to household hazardous waste facilities. Call the Household Hazards Line at 206-296-4692 or visit http://www.hazwastehelp.org/default.aspx for more information.

B. Individual dead animals weighing less than 15 pounds may be disposed in the general waste stream. Dead animals weighing more than 15 pounds, or dead animals disposed in quantity should be taken to a rendering plant, veterinary clinic, animal shelter, pet cemetery or buried on the property owners’ property, so long as no nuisance is created. If none of these methods are available, dead animals may be accepted at the Cedar Hills Regional Landfill or other designated facility when accompanied by a Waste Clearance Decision.

C. Animal excrement is accepted under the following conditions:
