Comparison: State vs. Federal

Rules. Maryland has developed effluent standards and limitations in compliance with the federal Clean Water Act and has specific chemical limitations for chlorine and toxic substances that are more stringent than the federal requirements. In addition, Maryland has protected surface waters where discharges are not allowed and has established water quality standards to protect waters of the state.

Each discharge permit, unless inappropriate, must specify average and maximum daily quantitative limits, in terms of weight, for the discharge of pollutants in the authorized discharge. For more information on discharge permits, see the state section NPDES PERMIT.

Administration and enforcement. The MDE is responsible for most of the administration and enforcement of the state's effluent limitations related to water pollution control. However, the MDA is responsible for some discharge limits for certain agricultural operations.
