12. Maximum Extent Practicable (MEP): MEP is defined in the Federal Register (U.S. EPA, 1999, p.
68754). This document says that “Compliance with the conditions of the general permit and the series
of steps associated with identification and implementation of the minimum control measures will
satisfy the MEP standard.” Minimum control measures are defined in the Federal Register as (1)
public education and outreach, (2) public participation/involvement, (3) illicit discharge detection and
elimination, (4) construction site runoff control, (5) post-construction runoff control, and (6) pollution
prevention/good housekeeping. MEP are the controls necessary for the reduction of pollutants
discharged from a MS4, which consist of a combination of BMPs, control techniques, system design
and such other provisions as described in the SWMP. Implementation of BMPs consistent with the
provisions of the stormwater management program required pursuant to this permit constitutes
compliance with the standard of reducing pollutants to the MEP. Stormwater management programs
must be assessed and adjusted, as part of an iterative process, to maximize their efficiency and make
reasonable progress toward as ultimate goal of reducing the discharge of pollutants to the MEP.

13. Municipal Separate Storm Sewer System (MS4): Pursuant to 40 CFR 122.26(b)(8) means a
conveyance or system of conveyances (including roads with drainage systems, municipal streets,
catch basins, curbs, gutters, ditches, manmade channels, or storm drains) owned or operated by the
United States, a State, Town, town, county, district, association, or other public body (created by or
pursuant to State law) having jurisdiction over disposal of sewage, industrial wastes, stormwater, or
other wastes, including special districts under State law such as a sewer district, flood control district
or drainage district, or similar entity, or an Indian tribe or an authorized Indian tribal organization, or
a designated and approved management agency under Section 208 of the Clean Water Act (CWA)
that discharges to waters of the United States or waters of the State that is designed or used for
collecting or conveying stormwater; that is not a combined sewer; and which is not part of a Publicly
Owned Treatment Works (POTW) as defined in 40 CFR 122.2.

14. Non-structural BMP: Non-structural BMPs are preventive actions that involve management and
source controls such as: (1) Policies and ordinances that provide requirements and standards to direct
growth to identified areas, protect sensitive areas such as wetlands and riparian areas, maintain and/or
increase open space, provide buffers along sensitive water bodies, minimize impervious surfaces,
and/or minimize disturbance of soils and vegetation; (2) policies or ordinances that encourage infill
development in higher density urban areas, and areas with existing storm sewer infrastructure; (3)
education programs for developers and the public about minimizing water quality impacts; (4) other
measures such as minimizing the percentage of impervious area after development, use of measures
to minimize directly connected impervious areas, and source control measures often thought of as
good housekeeping, preventive maintenance and spill prevention.

15. Outfall: Outfall means a point source as defined by 40 CFR 122.2 at the point where a municipal
separate storm sewer discharges to waters of the United States and does not include open
conveyances connecting two municipal separate storm sewers, or pipes, tunnels or other conveyances
which connect segments of the same stream or other waters of the United States and are used to
convey waters of the United States.

16. Permittee: The owner or operator issued this permit.

17. Point Source Discharge of Stormwater: Any discernible, confined and discrete conveyance including,
but not specifically limited to, any pipe, ditch, channel, tunnel, conduit, well, or discrete fissure from
which stormwater is or may be discharged to waters of the state.

18. Redevelopment: "Redevelopment" has the same meaning as in G.S. 143-214.7.

22 DRAFT NCS000488 01/27/2021

19. Storm Sewer System: Is a conveyance or system of conveyances which are designed or used to
collect or convey stormwater runoff that is not part of a combined sewer system or treatment works.
This can include, but is not limited to, streets, catch basins, pipes, curbs, gutters, ditches, man-made
channels or storm drains that convey stormwater runoff.

20. Stormwater Associated with Industrial Activity: The discharge from any point source which is used
for collecting and conveying stormwater and which is directly related to manufacturing, processing or
raw material storage areas at an industrial site. Facilities considered to be engaged in "industrial
activities" include those activities defined in 40 CFR 122.26(b)(14). The term does not include
discharges from facilities or activities excluded from the NPDES program.

21. Stormwater Control Measures (SCM): "Stormwater Control Measure" or "SCM," also known as a
structural "Best Management Practice" or "BMP," means a permanent device that is designed,
constructed, and maintained to remove pollutants from stormwater runoff by promoting settling or
filtration; or to mimic the natural hydrologic cycle by promoting infiltration, evapo-transpiration,
post-filtration discharge, reuse of stormwater, or a combination thereof.

22. Stormwater Management Program: The term Stormwater Management Program refers to the
comprehensive stormwater management program that is required to be developed and implemented
by MS4 permittees.

23. Stormwater Management Plan (SWMP): The Stormwater Management Plan is the written plan that is
used to describe and define the various control measures and activities the permittee will undertake to
implement the stormwater management program to meet the MEP standard.

24. Stormwater Runoff: The flow of water which results from precipitation and which occurs
immediately following rainfall or as a result of snowmelt.

25. Total Maximum Daily Load (TMDL): A TMDL is a calculation of the maximum amount of a
pollutant that a waterbody can receive and still meet water quality standards, and an allocation of that
amount to the pollutant's sources. A TMDL is a detailed water quality assessment that provides the
scientific foundation for an implementation plan. The implementation plan outlines the steps
necessary to reduce pollutant loads in a certain body of water to restore and maintain water quality
standards in all seasons. The Clean Water Act, Section 303, establishes the water quality standards
and TMDL programs.

26. Waste Load Allocation (WLA): A WLA is a TMDL pollutant reduction target allocating a specific
load reduction to specific point source discharge(s) of the pollutant. Some stormwater point source
discharges are assigned a WLA.
