Subject: Draft NPDES Permit Number NCS000425
Dear Ms. Hill: - --
Enclosed for your review and comment is the draft Phase II NPDES Stormwater Permit
for the County of Onslow .
In a letter dated May 18, 2005, the Director, in response to the great volume of concern
expressed regarding DWQ ability to adequately protect our coastal waters and resources utilizing
low density impervious surface limits, directed DWQ staff to withhold issuance of individual
Phase II permits for communities within the Coastal Counties until such time that a review of the
effectiveness of the proposed post -construction stormwater control measures in the draft Phase lI
Permits and the existing State Coastal Stormwater Program could be completed. DWQ has
decided to move forward with drafting Phase U Permits for the coastal communities.
Specifically for the coastal communities, we are purposing development activities located
with the permittee's jurisdiction that disturb 5,000 square feet or more of land shall control the
runoff from the first one and one half inch of rainfall. In addition, all impervious surfaces, except
for roads, paths, and water dependent structures, shall be located at least 30 feet landward of all
perennial and intermittent surface waters. Redevelopment activities that meet the provisions of
15A NCAC 2H .1002(14) shall not be required to comply with these specific requirements.
Purposed structural stormwater controls include the following criteria:
(1) Remove an 85% average annual amount of Total Suspended Solids.
(2) For wet detention ponds draw down the treatment volume no faster than 48 hours, but
no slower than 120 hours.
(3) Discharge the storage volume at a rate equal or less than the pre -development
discharge rate for the 1-year, 24-hour storm.
(4) Meet the General Engineering Design Criteria set forth in 15A NCAC 2H .1008(c).
We believe that this draft permit will provide your community with the flexibility vital for
your community, while at the same time safeguarding and protecting our natural environment for
future generations of North Carolinians.

PART 1 PERMIT COVERAGE
During the period beginning on the effective date of the permit and lasting until expiration, the
County of Onslow is authorized to discharge stormwater from the municipal separate storm
sewer system (MS4) to receiving waters, New River Sub Basin, within the White Oak River Basin
River Basin, Such discharge will be controlled, limited and monitored in accordance with the permittee's
Comprehensive Stormwater Management Program Report, herein referred to as the Stormwater Plan. The
Stormwater Plan includes components of the permittee's Phase lI Municipal NPDES Stormwater Permit
Application, NPDES Stormwater Permit Application Comprehensive S0mwater Management
Program Report and any approved modifications. ,41 l;

The Division may deny or revoke coverage under this permit for separate entities and require
independent permit coverage as deemed lawfully and reasonably necessary. In addition, the
permittee may petition the Division to revoke or deny coverage under this permit for specific
entities.
6. Under the authority of Section 402(p) of the Clean Water Act and implementing regulations 40
CFR Part 122, 123 and 124, North Carolina General Statutes 143-215.1 and Session Law 2004-
163 and in accordance with the approved Stormwater Plan, all provisions contained and
referenced in the Stormwater Plan are enforceable parts of this permit. The pennittee will
develop and implement its approved Stormwater Plan in accordance with Section 402(p)(3)(B) of
.the Clean Water Act, provisions outlined by the Director, and the -provisions of this permit.
The permit requires the development and proper implementation of the Stormwater Management

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.

15. Non-stormwater Discharge Categories
The following are categories of non-stormwater discharges that the permittee must address if it
identifies them as significant contributors of pollutants to the storm sewer system: water line
flushing, landscape irrigation, diverted stream flows, rising groundwater, uncontaminated
groundwater infiltration, [as defined in 40 CFR 35.2005(20)], uncontaminated pumped
groundwater, discharges from potable water sources, foundation drains, air conditioning
condensation, irrigation water, springs, water from crawl space pumps, footing drains, lawn
watering, individual residential 'car washing, flows from riparian habitats and wetlands,
dechlorinatedd-swimming pool discharges, and street wash water/)(discharges or [lows from fire
fighting activities are excluded from the definition of illicit�discharge and only need to be
s'Cr'6:r.•'S.
addressed where they are identified as significant sources of pollutants to waters of the United
States).', "„'
16. Non-structural BMP
Non-structural BMPs are preventive actions that;invol"vertu aan gement and source controls such
as: (1) Policies and ordinances that provide regUirementsia d standards to direct growth to
,f�
identified areas, protect sensitive areas su�as wetlands and riparian areas, maintain and/or

increase open space, provide buffers. al ongtsensitwe.water bodies, minimize impervious surfaces,
and/or minimize disturbance of soils nd vegetation; (2) policies or ordinances that encourage
infill development in higher density urban,areas, and areas with existing storm sewer
infrastructure; (3) education programs forridbvelopers 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 mininiize directly connected impervious areas, and source
control measures often thouglFb -was good housckeeping, preventive maintenance and spill
prevention.
17. Outfall
The point of wastewater or stormwater discharge from a discrete conveyance system. See also
point source discharge of stormwater.
18. Permittee
The owner or operator issued this permit.
19. Point Source Discharge of Stonnwater
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.
20. Redevelopment
Means any rebuilding activity unless that rebuilding activity;
1. Results in no net increase in built -upon area, and
2. Provides equal or greater stormwater control than the previous development.

21. Stormwater Runoff
The flow of water which results from precipitation and which occurs immediately following
rainfall or as a result of snowmelt.
22. 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 qualityistandards in all seasons.
The Clean Water Act, Section 303, establishes the watequality standards and TMDL programs.
23. Toxic Pollutant r.
Any pollutant listed as toxic under Section 307(a)(1) of the�Clean Water Act.
