Subject: Draft NPDES Permit Number NCS000398
Dear Mr. Weaver:
Enclosed for your review and comment is the draft Phase lI NPDES Stormwater Permit
for the County of New Hanover.
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 11 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.

16, Non-structural BMP
Non-structural BMPs are preventive actions that involve,management and source controls such
as: (1) Policies and ordinances that provide requirernentJand standards to direct growth to
identified areas, protect sensitive areas such(a wetlands` and riparian areas, maintain and/or
increase open space, provide buffers,along'sensiti`ve.water bodies minimize impervious surfaces,
and/or minimize disturbance of oils nd vge ation; (2) policies or ordinances that encourage
�a-
sity�urr3 -�
infill development in higher den ban,areas, and areas with existing storm sewer
infrastructure; (3) education programs f8fa&velopers 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 thoughtH'as-good housekeeping, 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 pernut.
19. 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.
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 stonnwater control than the previous development.

PET NO. NCS000398
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 th�eientific 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 w er,,q al ty,standards in all seasons.
The Clean Water Act, Section 303, establishes the wate quality st ndards and TMDL programs.

RE: Amendment to the New Hanover County NPDES Phase 11 Application
Dear Mr. Lau,

DENR _ WATER QUALITY
POINT SOURCE BRANCH
Attached are section modifications to the County's NPDES Phase lI Application in
response to your June 21, 2004 letter. Changes are in bold face.
Thank you for your assistance. Please feel free to contact me if you have any questions
or comments.
Sincerely,
David F. Weaver
Assistant County Manager
New Hanover County
DFWlpdm

Neal Lewis, NHC Parks Director

on the need to eliminate all illicit discharge and to be sensitive to
their presence. Signs will be posted on County MS4 properties to
notify the public against illicit discharges. Recycling programs are
in place in the County for such materials as used oil and household
hazardous waste. Other outreach programs will occur as
previously discussed. Signs and other outreach programs will
provide appropriate phone numbers for Engineers and Parks
for public contact.
7.3.9 Decision Process
The decision process for the illicit discharge detection and
elimination program was initiated by both the County's continuous
commitment to improving estuarine water quality and by the
requirements of the NPDES Phase II program. The rationale for
the County's program for illicit discharge detection and
elimination, individual BMPs, measurable goals, and designation of
responsible persons has been to recognize the importance of
estuarine water quality for the County's quality of life and to
reverse the general process of water quality deterioration in the
County. The County has been at least partially successful as
indicated by improved water quality in Futch's Creek, and
anticipated improvements in Pages, Howe, and Hewletts Creek.
The County's support of the estuarine creek monitoring programs
(see Attachment Eight) and its implementation of programs far
beyond the minimum required attest to the County's emphasis on
an environmentally committed decision process and rationale. It is
critical to note that the County has implemented ordinances and
programs that far exceed the minimum needed for the elimination
of illicit discharge on County MS4 properties.
7.3.10 Evaluation
The success of this measure will be accomplished through the
estuarine creek monitoring program, the existence of described
programs, and the lack of illicit discharges on County MS4
properties.
7.4 Construction Site Stormwater Runoff Control
The County relies on State Stormwater regulatory programs and the
County's State -delegated programs for Erosion and Sediment Control to
meet this requirement. This program, which has been in place for well
over ten years and is annually evaluated by the State, is well -respected.
Public complaints about sediment run-off have traditionally been
directed to the County Engineering Department. This information
will be listed in appropriate outreach materials.

7.5 Post -construction Stormwater Management in New Development and
Redevelopment
7.5.1 through 7.5.7
The County's existing ordinances will be reviewed as outlined on
the following BMP Summary Table for compliance with this
section.
7.5.8 BMP Summary Table (see following page)
7.5.9 Non --structural BMPs
7.5.9.1 Please see the discussion in Section 3.
7.5.9.2 The CAMA Land -Use Plan encourages in -fill
development. The County Zoning Ordinance allows for
density development, if performance controls are
installed, in appropriate urban transition areas.
7.5.9.3 Please see earlier sections and attachments concerning
education programs for developers and the public.
7.5.9.4 The County Zoning Ordinance and drainage ordinance
have measures affecting the amount of and connectivity of
impervious surface.
7.5.10 Structural BMPs
Structural BMPs are required under ordinance as necessary for new
development. Structural BMPs, such as retention ponds, are
located on County MS4 properties as required.
7.5.11 Regulatory Mechanism
The County already has regulatory mechanisms in place (see
Attachments Two and Three). Development and re -development
is not allowed to impact septic field or system operations as
controlled under the building permit review procedure.
7.5.12 Operation and Maintenance
Operations and maintenance of structural BMPs are addressed in
County ordinances (see Attachments Three). The County is
directly responsible for structural BMPs on County MS4
properties, as enforced by State DWQ regulations.

Additional Information Request
New Hanover County County
Dear Mr. Weaver:
After a review of your permit application materials I found that there were a couple of pieces of
information that were not fully addressed. Please provide a letter detailing how the following pieces of
information will be addressed in New Hanover County's Stormwater Management Program.
1) Section 7.3 Illicit Discharge Detection and Elimination didn't mention a means for the public to report illicit
discharges. How will the county receive feedback from county residents regarding illicit discharges?
16 Section 7.4 Construction Site Stormwater Runoff doesn't offer a means for the public to notify the
appropriate authorities when erosion and sedimentation problems are observed. How does the county
receive sedimentation attd erosion control complaints?
3) Section 7.5 Post -Construction Storm Water Management in New Development and Redevelopment didn't
mention coordinating with the local health department to make sure that septic systems are not contributing
fecal contamination to the stormwater system. How will New Hanover County address this issue?
Please provide the requested information by Friday, July 23. If you have any questions about this
request don't hesitate to contact me at [phone], ext. 578.
