How an NPDES Stormwater General Permit Works
A stormwater general permit is both a permit and a handbook for compliance. Each general permit has a preamble (or fact sheet) that summarizes the factual, legal, methodological, and policy questions considered in drafting the permit. The information in the fact sheet often helps the reader better understand the intent of the provisions in the permit.
