GLOSSARY

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.

Construction Storm Water Program

Dischargers whose projects disturb one or more acres of soil or whose projects disturb less than one acre but are part of a larger common plan of development that in total disturbs one or more acres, are required to obtain coverage under the General Permit for Discharges of Storm Water Associated with Construction Activity. Construction activity subject to this permit includes clearing, grading and disturbances to the ground such as stockpiling, or excavation, but does not include regular maintenance activities performed to restore the original line, grade, or capacity of the facility. For more information, see the Construction Storm Water Program.

Municipal Storm Water Program

The Municipal Storm Water Permitting Program regulates storm water discharges from municipal separate storm sewer systems (MS4s). Storm water is runoff from rain or snow melt that runs off surfaces such as rooftops, paved streets, highways or parking lots and can carry with it pollutants such as: oil, pesticides, herbicides, sediment, trash, bacteria and metals. The runoff can then drain directly into a local stream, lake or bay. Often, the runoff drains into storm drains which eventually drain untreated into a local waterbody. For more information, see the Municipal Storm Water Program.

Industrial Storm Water Program

The Industrial General Permit is an NPDES permit that regulates discharges associated with 10 broad categories of industrial activities. The Industrial General Permit requires the implementation of Best Available Technology Economically Achievable (BAT) and Best Conventional Pollutant Control Technology (BCT) to achieve performance standards. For more information, see the Industrial Storm Water Program.

Compliance Actions

Compliance actions are formal enforcement actions that impose sanctions and/or require compliance. Compliance Actions include Notices to Comply (NTC), Notices of Noncompliance (NNC), Time Schedule Orders (TSO), Cease and Desist Orders (CDO) and Clean Up and Abatement Orders (CAO).

Formal Enforcement

Formal enforcement actions are statutorily based actions to address a violation or threatened violation of water quality laws, regulations, policies, plans, or orders.

Informal Enforcement Actions

Informal enforcement actions are enforcement actions taken by Water Board staff that are not defined in statute or regulation. Informal enforcement action can include any form of communication (oral, written, or electronic) between Water Board staff and a discharger concerning an actual, threatened, or potential violation. Informal enforcement actions cannot be petitioned to the State Water Board.

The purpose of an informal enforcement action is to quickly bring an actual, threatened, or potential violation to the discharger's attention and to give the discharger an opportunity to return to compliance as soon as possible. The Water Board may take formal enforcement action in place of, or in addition to, informal enforcement actions.

Penalty Actions

Penalty Actions are formal enforcement actions where administrative or judicial actions impose a penalty or require the completion of a project associated to a monetary amount. Penalty actions include liabilities imposed with an Administrative Civil Liability (ACL) and settlement agreements pursuant to Government Code section 11415.60.
