Subject: Additional Information Request
NPDES Stormwater Permit Application
Permit Number NCS000465.
Wake County
The Division of Water Quality (DWQ), Stormwater Permitting Unit has reviewed your Phase II
Stormwater Permit Application and Stormwater Management Program Report, received May 4,
2004. We are requesting additional information and revisions to the submittal. The following
items pertain to your proposed Public Involvement program, Illicit Discharge Detection and
Elimination program, and Post -Construction Runoff Control requirements.
Post -Construction Runoff Control
a) Your submittal states that Morrisville already adheres to Neuse Riparian Buffer Rule
(15A 2B .0233) requirements and will adopt an ordinance that "will incorporate NSW
requirements, at a minimum in the Neuse River Basin within the Town's jurisdiction"
(Section 7.5.11). If the Town chooses to implement Neuse Nutrient Sensitive Water
(NSW) requirements as outlined in the Neuse Stormwater Rule (15A NCAC 2B .0235)
throughout its jurisdiction, this action will fulfill the Post -Construction Requirements as
established in Session Law 2004-163 and the Stormwater Management Rule (SMR)
Section 10. However, if the Town retains current criteria for New Development and
Redevelopment (as outlined in Section 7.5.1.1 in the Town's report) in the Cape Fear
portion of its jurisdiction, the Town will not meet Phase II requirements.
Current regulations for development projects in Morrisville do not address High and Low
Density development in accordance with SMR Section 10(e), and therefore would not
fulfill Post -Construction requirements in the Cape Fear portion of the Town's
jurisdiction. Please revise your submittal to clarify whether (1) an ordinance
implementing Neuse NSW requirements will be adopted throughout the Town's
jurisdiction, or (2) in lieu of adopting Neuse NSW requirements in the Cape Fear portion
of the Town's jurisdiction, what ordinances will be adopted to meet Phase II
requirements as outlined in the SMR Section (10)?
Please note that DWQ has developed a Model Stormwater Program for Nitrogen Control
in the Neuse River Basin.

b) Section 7.5.3: Please elaborate on how the Town will coordinate with Wake County and
the N.C. Department of Environmental Health (DEH) on controlling sources of fecal
coliform. How will the Town exchange information with the County and/or NC DEH to
evaluate potential impacts to its Stormwater Management Program?
Illicit Discharge Detection and Elimination
c) The Town of Morrisville's submittal did not include plans to cross -train employees on
illicit discharge detection (Section 7.3). How does the Town plan to train municipal staff
on detecting and reporting illicit discharges? Also, please describe how that training will
be coordinated with the Town's training program for the `Pollution Prevention and Good
Housekeeping for Municipal Operations' minimum measure.
Public Involvement and Participation
d) The Town's application indicates plans to create a Solid Waste Advisory Committee
(SWAG) to advise the Town Board of Commissioners on matters concerning the disposal
of solid waste (Section 7.2.3.1). While the SWAC's duties could be relevant to
stormwater issues, the focus of this committee is on solid waste. The Town could
consider expanding the duties of SWAC to include more specific input on the Stormwater
Program and stormwater issues that affect the community, or the Town could establish a
citizens' group focused on stormwater issues. Please provide additional information to
address the Town's plans.
e) The Town plans to conduct public hearings for new ordinances to allow the public to
comment on the development of the Stormwater Program and to "facilitate public
meetings as needed on specific stormwater-related topics" (Section 7.2.3.2). The Town
should conduct at least one public meeting to allow citizens to review and comment on its
Stormwater Management Program Report (i.e., Stormwater Plan), prior to the public
hearing and adoption process for new ordinances. Please provide information about
plans for the Stormwater Plan public review process.
We cannot continue processing your application for a stormwater permit until we resolve the first
deficiency associated with Post -Construction Runoff Control (item (a)). The other points are
considered minor but should be addressed as timely as possible. Please provide the requested
information and changes by January 18, 2005. If you have any questions, please feel free to call
me at [phone] ext. 529.
Sincerely,
Bethany A. Georgoulias
