Subject: NPDES Permit Number NCS000406
Enclosed for your review and comment is the draft Phase II NPDES Stormwater Permit
for the City of Wilmington.
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 11 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 II
Permits and the existing State Coastal Stormwater Program could be completed. DWQ has
decided to move forward with drafting Phase lI 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 211.1002(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.

completed in one or more of the following ways:
• In separate stages
• In separate phases
• In combination with other construction activities
It is identified by the documentation (including but not limited to a sign, public notice or hearing,
sales pitch, advertisement, loan application, drawing, plats, blueprints, marketing plans,
contracts, permit application, zoning request, or computer design) or physical demarcation
(including but not limited to boundary signs, lot stakes, or surveyor markings) indicating that
construction activities may occur on a specific plot. .
It can include one operator or many operators.

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.

15. Non-stormwater Discharge Cate ories
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,
dechlorinated swimming pool discharges, and street wash water (discharges or flows from fire
fighting activities are excluded from the definition of illicitdis hl gee and only need to be
J�raddressed where they are identified as significant sources of pollutants. to waters of the United
States).

17. Outfall
The point of wastewater or stormwater discharge from a discrete conveyance system. See also
point source discharge of storinwater.
18. Permittee
The owner or operator issued. this permit.
19. Point Source Discharge of Stor nwater
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 n essary to reduce pollutant
loads in a certain body of water to restore and maintain water quali y standards in all seasons.
The Clean Water Act; Section 303, establishes the water. quality standards and TMDL programs.
23. Toxic Pollutant
Any pollutant listed as toxic under Section 307(a)(I) of 'tile'@lean Water Act.
