Dear Ms. Karoly:

DENR - WATER Q JALITY
WETLANDS AND STORMWATER BRANCH
The Nash - Rocky Mount Board of Education is proposing to build a new high school facility on
an approximately 60.52-acre property located in the City of Rocky Mount, Nash County, North
Carolina. The development include the construction of a classroom building, athletic facilities,
and parking lots.
The attached Pre-Construction Notification (PCN) is being submitted in order to obtain
Nationwide Permit 39. The proposed construction will require impacts to 281 linear feet of
jurisdictional stream channel and 0.138 acre of jurisdictional wetland. These stream impacts
occur on an unnamed tributary to Maple Creek and an unnamed tributary to the Tar River. The
proposed construction of a sewerline easement will result in impacts to 1,000 square feet of Tar-
Pamlico Riparian Buffer associated with the unnamed tributary to the Tar River. Mitigation for
impacts to jurisdictional areas will be provided through the NCEEP In-lieu Fee program.
The proposed construction will have no effect on red-cockaded woodpecker, dwarf
wedgemussel, or Tar River spinymussel, the federally protected species known to have a range
extending into Nash County. Suitable habitat for these species does not exist within the parcel
boundaries. A Natural Heritage Program records review on June 30, 2009 indicated no
occurrences of red-cockaded woodpecker, dwarf wedgemussel, or Tar River spinymussel within
3.0 miles of the property. This project will have no effect on these species.
Please comment on the attached PCN at your earliest convenience. Please contact me if you
have any questions or need any further information.
Sincerely,
ENVIRONMENTAL SERVICES, INC.

of Uses for non-electric utility lines.
D. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
The majority of the site will be disturbed by this project, but the high school facilities have been placed to avoid as much of the
jurisdictional areas as practicable. The majority of Wetland #2, 198 feet of Stream #2, 259 linear feet of Stream #1, and all of
Wetland #4 have been avoided. The sewerline easement in the southern corner of the property has been placed so that it will
cross Stream #1 at a perpendicular angle, which will minimize stream and buffer impacts.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
A retaining wall will be placed on the south side of Wetland #2 to minimize impacts to the wetland and the north end of Stream
#2. Early designs did not include this retaining wall, which would have resulted in higher wetland impacts. Proper sediment
and erosion control measures will be implemented during and after construction.
2. Compensatory Mitigation for Impacts to Waters of the U.S. or Waters of the State

Expiration of Acceptance: August 24, 2010
County: Nash
The purpose of this letter is to notify you that the North Carolina Ecosystem Enhancement Program (NCEEP) is willing to accept
payment for impacts associated with the above referenced project. Please note that this decision does not assure that the payment will
be approved by the permit issuing agencies as mitigation for project impacts. It is the responsibility of the applicant to contact these
agencies to determine if payment to the NCEEP will be approved. You must also comply with all other state, federal or local
government permits, regulations or authorizations associated with the proposed activity including SL 2009-337: An Act to Promote
Compensatory Mitigation Private Mitigation Banks,
This acceptance is valid for nine months from the date of this letter and is not transferable. If we have not received a copy of the
issued 404 Permit/401 Certification/CAMA permit within this time frame, this acceptance will expire. It is the applicant's
responsibility to send copies of the permits to NCEEP. Once NCEEP receives a copy of the permit(s) an invoice will be issued based
on the required mitigation in that permit and payment must be made prior to conducting the authorized work. The amount of the In
Lieu Fee to be paid to NCEEP by an applicant is calculated based upon the Fee Schedule and policies listed at www.nceep.net.
Based on the information supplied by you the impacts that may require compensatory mitigation are summarized in the following
table.

Re: Rocky Mount High School, Bethlehem Road, Rocky Mount
Dear Ms. Karoly:
The City of Rocky Mount has reviewed and approved the stormwater management plan for the proposed
Rocky Mount High School. The City operates a Certified Local Stormwater Program under Phase II
NPDES Stormwater Program and is commited to requiring on-site stormwater management measures,
such as riparian buffers, bioretention cells, constructed wetlands, and level spreaders, for any new
development within our jurisdiction. All development is also required to meet stringent water quality
requirements in accordance with the City of Rocky Mount's Land Development Code, the City of Rocky
Mount's Stormwater Management Program, the Tar-Pamlico River Basin Riparian Buffer Protection
Rules, and the Tar-Pamlico Nutrient Management requirements.
If you have further questions or need additional information, please feel free to contact me at

Multiple BMP's have been utilized to reduce the nutrient loading onsite, including
15 Bioretentions and 2 Wet Dention Ponds.
The remaining 1.27 Ibs/acre/yr of Nitrogen and the 0.07 0.1lbs/acre/yr of Phosphorous
will be bought down in the amount of $50,106.44 with Nitrogen governing.
