Compliance and Enforcement

Local municipalities generally have the lead responsibility for ensuring that industry and businesses comply with pretreatment requirements. This responsibility is well-placed because local agencies can detect and respond quickly to compliance issues. The Clean Water Act also provides for pretreatment enforcement by states, tribes, U.S. EPA, and citizens.
