Under the Agricultural Use Exclusion, certain wastes used in agricultural operations – including growing crops, raising livestock and fowl and some other uses - are excluded from regulation as solid waste. Typical waste materials and uses are:
- waste water sludges and crop residues applied to land as soil amendments
- industrial food processing wastes and spent brewery grains fed to livestock
- wood wastes, straw and yard debris used as livestock bedding
The exclusion, which dates to the early 1970s, prevents the regulation of agricultural operations as solid waste management facilities. In the more than four decades since the exclusion was adopted, agricultural operations have found many productive uses for materials once considered waste.Sign up to receive email notifications.
