NPDES Stormwater Permit Application
Dear Ms. Georgoulias:
Progress Energy received your letter dated May 17, 2011, indicating that storm water discharges
specified in the submitted NPDES Permit Renewal Application (submitted to the Division of Water
Quality on December 7, 2010, not on May 4, 2011, as indicated in your letter) will be permitted
separately under an individual NPDES Stormwater Permit. Progress Energy will endeavor to correct
any misunderstanding about the storm water outfalls located at the Cape Fear Plant based on the
additional information requested.
Storm water from various drains and sumps in the power block area contributes flow to several
wastewater streams within the Cape Fear Plant system. These contributions are described in Form
2C and in the attachments to Form 2C. All wastewater streams combine and discharge to a tributary
of the Cape Fear River via Outfall 007. These storm water flows are included in the wastewater
permit and are not subject to the individual storm water permit. The four storm water outfalls
described in Form 2F are the outfalls where storm water from industrial activity areas discharge to a
surface water without combining with wastewater. As requested, revised Site Drainage Maps
(Attachment 5 of the original submittal) with more detail are enclosed.
As described in Form 2F, following an exceptional rainfall event, Outfalls SW -001 and SW -008
could potentially release storm water to surface water from inactive ash ponds which store coal ash.
No coal ash has been sluiced to these ponds for more than 35 years. These are perched ponds
meaning that the drainage areas contain only the precipitation that falls directly on the ash pond
surface area. Since these ponds have been inactive, there have been no releases from these two storm
water outfalls.
In Form 2F IV B, the descriptions of the other two storm water outfalls are provided. Along the
western perimeter of the drainage area for Outfall SW -2, there is a railroad spur that is used to
deliver coal to the plant. The small contribution of runoff (< 1 acre) from along the railroad track
(the industrial activity) flows through a pipe under the access road, then sheet flows over an
employee parking lot and across a field to Shaddox Creek. The runoff is collected in a low area in
the fKg pgjgq ,�%peath a berm to a discharge pipe to the creek. There have never been storage

areas or disposal areas, no loading or access areas, and,no pesticides, fertilizers, etc. applied within
this drainage. Impervious areas located within this drainage area include an access road that
parallels the railroad, a ,gravel parking lot, and a small employee picnic shelter.
The small drainage area for Outfall SW -3 (— 2. acres) is along the swale between the plant access
road and the north-west dike of the 1985 ash pond. Except for heavy rainfall events, storm water
rarely flows from this outfall to drainages that eventually go to Shaddox Creek. Apart from an ash
sluice pipeline, this area is away from industrial activities at the power plant area. There have never
been,storage areas or disposal areas, no loading or access, areas, and no pesticides, fertilizers, etc.
applied within this drainage.
Also enclosed is a check ($860.00) for the NPDES Storm Water Permit fee. Please contact Ms.
Robin Bryson, Environmental Specialist in our corporate office, at [phone] or email to
