GLOSSARY

Best Management Practices (BMPs)

Scheduling of activities, prohibitions of practices, maintenance procedures, and other
management practices to prevent or reduce the discharge of pollutants. BMPs also
include treatment requirements, operating procedures, and practices to control site
runoff, spillage or leaks, sludge or waste disposal, or drainage from raw material
storage.

Chain of Custody

Form used to track sample handling as samples progress from sample collection to the
laboratory. The chain of custody is also used to track the resulting analytical data from
the laboratory to the client. Chain of custody forms can be obtained from an analytical
laboratory upon request.

Debris

Litter, rubble, discarded refuse, and remains of destroyed inorganic anthropogenic
waste.

Detected Not Quantifiable

A sample result that is between the Method Detection Limit (MDL) and the Minimum
Level (ML).

Discharger

A person, company, agency, or other entity that is the operator of the industrial facility
covered by this General Permit.

Drainage Area

The area of land that drains water, sediment, pollutants, and dissolved materials to a
common discharge location.

Effective Date

The date, set by the State Water Resources Control Board (State Water Board), when
at least one or more of the General Permit requirements take effect and the previous
permit expires. This General Permit requires most of the requirements (such as
SMARTs submittals, minimum BMPs, sampling and analysis requirements) to take
effect on July 15, 2015.

Effluent

Any discharge of water either to the receiving water or beyond the property boundary
controlled by the Discharger.

Effluent Limitation

Any numeric or narrative restriction imposed on quantities, discharge rates, and
concentrations of pollutants that are discharged from point sources into waters of the
United States, waters of the contiguous zone, or the ocean.
