Composting Program

Composting contributes to Oregon’s waste recovery goals thanks to the efforts of commercial and agricultural composting operations and citizens who compost in their back yards. On this page you will find information on permits and permit applications, recent studies on quality issues, updates on the Department’s policy work, and links to lots of useful information on how to make and use compost.


Composting Facility Rules
The amended composting rules adopted by the Environmental Quality Commission in August 2009 were filed by the Secretary of State and became effective September 14, 2009. You may read and download the rules at the Secretary of State’s Web site.
