TECHNICAL CONSIDERATIONS

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 (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.
