Re: Section 401 Water Quality Certification application
Dear Mr. Landseidel:
On August 27, 2009, the North Carolina Division of Water Quality (Division) received your application for a 401 General
Water Quality Certification to impact 0.133 acres of wetlands to construct the Dan River Combined Cycle Turbine Project
in Eden NC in Rockingham County. Additional information is required in order that we may determine your project's
compliance with 15A NCAC 2H.0500. The Division will require this information in order to process your application to
impact protected wetlands and/or streams on the subject property. Therefore, we will place this project on hold as
incomplete until we receive this additional information, and if we do not receive the additional information requested
below, we will have to move toward denial of your application as required by 15A NCAC 2H.0506. Please provide the
following information so that we may continue to review your project.
1. Please provide complete site plans on full plan sheets at a scale of no smaller than 1"=50' with existing
and proposed topographic contours shown.
2. Please provide an inventory of imperviousness surfaces in each drainage area. The inventory should
include all proposed building footprints, roads, driveways, sidewalks, gravel-surfaced areas, amenity
areas, etc. A Stormwater Management Plan (SMP) must be provided for any drainage areas that exceed
24 percent imperviousness. For each BMP, provide a completed BMP Supplement Form with all the
required items (see http://h2o.enr.state.nc.us/su/bmp forms htm). Per NCAC 213 15A: 02H.1000, a
"drainage area" is defined as "the entire area contributing surface runoff to a single point."
3. The Division is aware that the US Army Corps of Engineers has requested additional information for this
project in a notification dated September 3, 2009. Please provide us with a copy of your response to
these items.
Please respond in writing within 30 calendar days of the date of this letter by submitting two copies of this information;
one copy should be submitted to Sue Homewood at the address on this letterhead, and one copy to Ian McMillan N. C.
Division of Water Quality, Wetlands/401 Certification Unit, 1650 Mail Service Center, Raleigh, NC 27699-1650. If you
will not be able to provide the requested information within that timeframe, please provide written confirmation that you
intend to provide the requested information, and include a specific timetable delineating when the requested materials will
be provided. If we do not hear from you in 30 calendar days, we will assume that you no longer want to pursue this
project and we will consider the project as returned.
