Dear Mr. Greback:
Enclosed for your review and comment is the draft Phase 2 NPDES Stormwater Permit for the
Town of Lewisville. Following an appropriate public notice and comment period, we anticipate
this permit will become effective in the 4th quarter of 2005.
After a review of your permit application materials, I found that it was well written and sufficient
to issue the permit. Please carefully inspect the draft permit and update your Stormwater
Management Program Plan to reflect any changes that may be necessary to comply with the
permit. In particular, update Section 7.5 of your plan to address the requirements for post -
construction stormwater management in new development and redevelopment. Please be sure to
address how your community will address the long-term maintenance of BMPs that are
constructed in your jurisdiction.
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.
We look forward to receiving your comments on this draft permit and continuing to work
together for the benefit of your community and North Carolina. I anticipate this permit will go
out for a 30-day public notice period on September 6, 2005. Please submit any comments you
may have to 1ne by the end of the public notice period on October 7, 2005. If you have any

JOHN A. WHITSON, TOWN MANAGER
P.O. BOX 547
LEWISVILLE, NC 27023-0547
Subject: NPDES Phase II Stormwater Program
2000 U.S. Census - Notification of Coverage
John A. Whitson:
[n 1990 the U.S. Environmental Protection Agency's (EPA) Phase I stormwater program was promulgated under the
Clean Water Act. Phase I relies on National Pollutant discharge Elimination System (NPDES) permit coverage to
address stormwater runoff from: ( l) "medium" and "large" municipal separate storm sewer systems (MS4s) generally
serving populations of 100,000 or greater, (2) construction activity disturbing 5 acres of land or greater, and (3) ten
categories of industrial activity. The NPDES Stormwater Phase 11 Final Rule was promulgated in December 1999 and is
the next step in EPA's effort to preserve, protect, and improve the Nation's water resources from polluted slormwater
runoff. The Phase II program expands the Phase I program by requiring additional operators of MS4s in urbanized areas
and operators of small construction sites, through the use of NPDES permits, to implement programs and practices to
control stormwater runoff. Phase 11 is intended to further reduce adverse impacts to water quality and aquatic habitat by
instituting the use of controls on the unregulated sources of storm water discharges that have the greatest likelihood of
causing continued environmental degradation.
The NPDES Stormwater Phase II Final Rule requires nationwide coverage of all operators of small MS4s that are
located within the boundaries of a Bureau of the Census defined "urbanized area" based on the latest decennial Census.
The Bureau of Census has recently released data detailing the 2000 Census urbanized areas and using G1S data files
produced by the Bureau of Census, North Carolina Department of Environment and Natural Resources staff has
compiled a list of municipalities and counties that we believe fall in whole or in part within one or more of the seventeen
census -designated urbanized areas in North Carolina.
We are writing to you to notify you that the Town of Lewisville has been identified as being located within a census
designated urbanized area. As a regulated community, you are required to develop a stormwater management program
and apply for stormwater permit coverage, if you own and operate a small MS4 or file a certification that the Town of
Lewisville does not own or operate a small MS4. The deadline for submitting your application package or
non -ownership certification is 18 months from the date of this letter. Application and certification documents, as well as
additional information on the NPDES stormwater program, are available for download at our web site . Our web address
is http:1/h2o.enr.state.nc.us/su/stormwater.htm1. if you have any questions about this letter, please feel free to contact me
