The Department of Energy and Environmental Protection (DEEP) regulates the discharge of industrial wastewater to the ground water, surface water, and to sewage treatment plants through permitting programs. Discharge limits and requirements for treatment, monitoring and reporting, designed to protect the waters of the state from pollution, are specified in all permits.
