Subject: Draft NPDES Permit Number NCS000445
Dear Mr. Pagley:
Enclosed for your review and comment is the draft Phase II NPDES Stormwater Permit
for the Town of Wrightsville Beach.
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 H 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 11
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.
