Clean Water Act National Pollutant Discharge Elimination System Compliance Monitoring Strategy

Provides inspection frequency goals for the core National Pollutant Discharge Elimination System program and for wet weather sources.

The strategy is implemented through the annual National Program Managers’ Guidance, which defines program priorities, implementation strategies and regional performance measures, which are in turn used in establishing yearly commitments for compliance monitoring activities with authorized states.
