GLOSSARY

Industrial Storm Water Program

Discharges associated with 10 broad categories of industrial activities are regulated under the Industrial Storm Water General Permit Order 2014-0057-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 under the Clean Water Act (CWA) 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.

Facilities

Include any construction facility enrolled under the storm water construction program that was active at least one day during the fiscal year.

Inspection

Inspections conducted by Regional or State Water Board staff, or US EPA. Inspection types include A Type and B Type Compliance, Complaint, Enforcement Follow-up, Inspection from Vehicle, No-Exposure Certification (NEC), Notice of Termination (NOT), NonFiler/Notice of Non-Applicability (NONA), and Non-compliance Follow-up.
