1. Will the facility slaughter cows?
- If yes: Solid waste from parts of the cow that have the potential to carry mad cow disease, known officially as bovine spongiform encephalitis, must be disposed of in a permitted landfill. This includes the brain, skull, eyes, and spinal cord from cows 30 months and older. Parts of the small intestine and the tonsils from all cows are required to be disposed of in a permitted landfill as well. This waste cannot be composted. For full details, see OAR 340-093-0030(43)(d) and OAR 340-096-0140(7).
- If no: Proceed to the next question.
2. Will all animal carcasses and other solid waste be hauled off-site to a landfill or compost facility permitted to receive the waste?
- If yes: If all waste is taken off-site to a permitted solid waste or compost facility, no solid waste permits are required at the processing or slaughter facility.
- If no: If waste will not be hauled off-site, waste may be composted or processed in an anaerobic digester. Proceed to the next question to determine if a permit is required.
3. Will more than 20 tons of Type 3 feedstocks be composted - or - will more than 100 tons of any combination of feedstocks be composted?
Type 1 feedstocks include wood, yard debris, and plant waste.
Type 2 feedstocks include manure and bedding.
Type 3 feedstocks include dead animals, meat, eggs, and dairy products.
- If yes: The facility must apply for a solid waste composting permit from DEQ unless the facility has a CAFO permit from ODA that covers the proposed composting operations. Also note that some materials must be removed from the carcasses of cattle and disposed of in accordance with OAR 603-029-0800 or OAR 603-029-0810. The materials that cannot be composted include the brain and spinal cord from cattle 30 months of age and older.
- If no: The facility does not require a DEQ solid waste composting permit, but must comply with the composting performance standards described at OAR 340-096-0070. For more information, read Composting Program overview website or contact the DEQ solid waste program in your region.
