"Local stormwater management program" or "local program" means the various methods employed by a locality to manage the quality and quantity of runoff resulting from land disturbing activities and shall include such items as local ordinances, permit requirements, policies and guidelines, technical materials, inspection, enforcement, and evaluation consistent with this article.
"Municipal separate storm sewer" means a conveyance or system of conveyances otherwise known as a municipal separate storm sewer system or "MS4," including roads with drainage systems, municipal streets, catch basins, curbs, gutters, ditches, man-made channels, or storm drains:

4. That is not part of a publicly owned treatment works.
"Municipal Separate Storm Sewer System Management Program" means a management program covering the duration of a permit for a municipal separate storm sewer system that includes a comprehensive planning process that involves public participation and intergovernmental coordination, to reduce the discharge of pollutants to the maximum extent practicable, using management practices, control techniques, and system, design and engineering methods, and such other provisions that are appropriate.
"Nonpoint source pollution" means pollution whose sources cannot be pinpointed but rather is washed from the land surface in a diffuse manner by stormwater runoff.
"Peak flow rate" means the maximum instantaneous flow from a given storm condition at a particular location.
"Permit" means an approval issued by the permit issuing authority for the initiation of a land-disturbing activity, or for stormwater discharges from an MS4.
"Permit issuing authority" means the Board, the Department, or a locality that is delegated authority by the Board to issue, deny, revoke, terminate, or amend stormwater permits under the provisions of this article.

"Water quality volume" means the volume equal to the first one-half inch of runoff multiplied by the impervious surface of the land development project.
"Watershed" means a defined land area drained by a river or stream or system of connecting rivers or streams such that all surface water within the area flows through a single outlet.
