A Plain English Guide to the EPA Part 503 Biosolids Rule
Publisher: U.S. Environmental Protection Agency, Washington, D.C., US.
The purpose of this document is to explain the intent and requirements of the Part 503 rule and to assist owner/operators in determining the extent to which their biosolids management operation is covered. To help clarify the intent of the Part 503 rule! this guidance document sometimes uses terms that do not appear in the rule itself and organizes information differently from the rule. For example, Chapter Two first describes land application of biosolids with the fewest regulatory requirements, then provides a discussion of land application of biosolids for which more regulatory requirements apply.
