GLOSSARY

Construction Storm Water Program

Dischargers whose projects disturb 1 or more acres of soil or are part of a larger common plan of development that in total disturbs 1 or more acres, are required to obtain coverage under the General Permit for Discharges of Storm Water Associated with Construction Activity (Construction General Permit, 2009-0009-DWQ).

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 (CWA Section 402) 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.

Inspection (Compliance and Non Compliance)

The Regional Board or State Board may inspect the facilities of any discharger at any time pursuant to Water Code, Section 13267. Compliance activities include all activities necessary to determine if discharges are in compliance with waste discharge requirements, NPDES permits, and related enforcement orders. Compliance inspections are classified as either Level A or Level B, with Level A being more thorough.
