What is the document called that authorizes the discharge of storm water under a general storm water permit?

The document that authorizes the discharge of storm water under a general storm water permit is known as a Certificate of Coverage. This certificate is issued to facilities that meet the eligibility criteria for coverage under a general permit. It signifies that the facility is allowed to discharge storm water runoff while adhering to the terms and conditions set forth in the permit. The Certificate of Coverage ensures that facilities are compliant with regulatory requirements and helps to mitigate environmental impacts associated with storm water discharges.

Understanding this document is critical for operators, as it outlines their responsibility and the environmental standards they must follow. This is part of a broader regulatory framework designed to protect water quality and adhere to environmental standards.
