Description NOTICE-PLEASE READ! Some of the regulatory guidance found in this document is no longer current. However, the technical guidance remains valid. State solid waste regulations were last amended in 2018, prompting a need to update these guidelines. Until an update is completed, please refer to RCW 70.95.306 for details specific to composting bovine and equine carcasses under routine conditions and when compost is distributed to a third party, as these statutory requirements have not changed. General regulatory information on agricultural composting can be found in WAC 173-350-220. Please contact the Department of Ecology’s Solid Waste Management program or your local health department if you have questions.

These guidelines were initially developed in 2005 in part to provide Washington bovine and equine producers, and parties that provide technical assistance to the producers, with an understanding of how to comply with regulatory and statutory requirements. In addition to addressing regulatory matters, these guidelines provide basic “how to” information for composting bovine and equine carcasses as one of a few possible animal mortality management techniques. Proper composting of other types of livestock is allowed in Washington, but this document addresses techniques solely for bovine and equine carcasses, and only for routine, day-to-day mortalities. They are not suitable for managing mortalities due to reportable diseases listed in WAC 16-70-010 (See Appendix B) or other animal emergencies. If you suspect the presence of any of the listed diseases, you should contact the State Veterinarian’s office and your local health department. In the event of an animal emergency, the State Veterinarian and your local health department will determine appropriate disposal options.
The mission of the Department of Ecology is to protect, preserve, and enhance Washington’s environment. To help us meet that goal, please consider the environment before you print or request a copy.
