GLOSSARY
- Industrial Stormwater Program
- Discharges associated with 10 broad categories of industrial activities are regulated under the Industrial Storm Water General
(Permit Order 97-03-DWQ, General Industrial Permit),
which is an NPDES permit.
- General Permit
- An NPDES permit issued under 40 CFR 122.28 that authorizes a category of discharges within a geographical area. A general permit is not specifically tailored for an individual discharger.
- National Pollutant Discharge Elimination System (NPDES)
- The NPDES permit program (Section 402 of the Clean Water Act ) controls water pollution by regulating point sources that discharge pollutants into waters of the United States. Point sources are discrete conveyances such as pipes or man-made ditches. Individual homes that are connected to a municipal system, use a septic system, or do not have a surface discharge do not need an NPDES permit; however, industrial, municipal, and other facilities must obtain permits if their discharges go directly to surface waters. US EPA has approved the Water Board’s program to issue NPDES permits.
