APPROVAL of 401 Water Quality Certification
Mr. Bill Gilmore
NC DOT
PO Box 25201
Raleigh, NC 27611-5201
Dear Mr. Gilmore:
You have our approval, in accordance with the attached conditions and those listed below, to impact 0.01
acres of wetlands or waters for the purpose of bridge maintenance and replacement, as you described in your
application dated July 24, 1998. After reviewing your application, we have decided that this impact is covered
by General Water Quality Certification Number 3100. This Certification is also covered by CAMA. This
Certification allows you to use Nationwide Permit Number 031 and 3112 when it is issued by the Corps of
Engineers. In addition, you should get any other federal, state or local permits before you go ahead with your
project including (but not limited to) Sediment and Erosion Control, Coastal Stormwater, Non-Discharge and
Water Supply Watershed regulations. This approval will expire when the accompanying 404 or CAMA permit
expires unless otherwise specified in the General Certification.
This approval is only valid for the purpose and design that you described in your application except as
modified below. If you change your project, you must notify us and you may be required to send us a new
application for a new certification. If the property is sold, the new owner must be given a copy of this
Certification and approval letter and is thereby responsible for complying with all conditions. If total wetland
fills for this project (now or in the future) exceed one acre, compensatory mitigation may be required as
described in 15A NCAC 2H.0506 (h) (6) and (7). For this approval to be valid, you must follow the
conditions listed in the attached certification.
If you do not accept any of the conditions of this certification, you may ask for an adjudicatory hearing.
You must act within 60 days of the date that you receive this letter. To ask for a hearing, send a written
petition conforming to Chapter 150B of the North Carolina General Statutes to the Office of Administrative
Hearings, P.O. Box 27447, Raleigh, N.C. 27611-7447. This certification and its conditions are final and
binding unless you ask for a hearing.
This letter completes the review of the Division of Water Quality under Section 401 of the Clean Water
Act. If you have any questions, please telephone John Domey at 919-733-1786.
Sincerely, :L?

Dear Sir:
SUBJECT

CAMA GENERAL PERMIT REQUEST FOR BRIDGE NO. 8 SOUTH
PRONG BAY RIVER, PAMLICO COUNTY.
The North Carolina Department of Transportation (NCDOT) proposes to replace
the referenced structure, located on SR 1343 in Bayboro, on existing location with
associated approach improvements. The existing structure, a cored slab bridge with 3
9' and 5 @ 8' spans, will be replaced with a cored slab bridge with 3 @ 30' spans.
Navigational clearance will average approximately 0.7 foot lower on the new structure,
however the passageway for the river will be widened from 67 feet to 90 feet. The
average daily flow of South Prong Bay River is 13.5 c.f.s. Your otfice advised us by
letter dated May 15, 1998, that a CAMA permit will be required for this project.
NCDOT planned to replace this bridge in 1993, however the project was
postponed due to the need to construct a temporary detour in wetlands as well as
uncertainty as to whether a CAMA permit would ever be required since less than 50% of
the physical value of the existing bridge would be replaced. The current design will not
require a temporary detour. Instead, construction will be done one lane at a time so one
will always be open for traffic. In addition, the entire structure will be replaced, thereby
ekceeding 50% of the value of the existing structure.
The area within the footprint of the project is salt marsh consisting primarily of
black needlerush (Juncus roemarianus), smooth cordgrass (Spartina alterniflora), and
marsh-elder (Iva frutescence). The proposed construction will involve fill with rip rap in

0.0 I acre of wetlands and 0.0 l acre of surface waters. In order to minimize these
impacts, 0.01 acre of existing bridge till will be excavated to natural ground elevation.
The proposed work is detailed in the attached drawings and permit application.
Application is hereby made for a General CAMA Permit and State Dredge and
Fill Permit as required for such activities. A check in the amount of $50.00 has been
transmitted to the DCM office in Raleigh to cover the CAMA processing fee. A copy of
the check is included herein. The adjacent property owners have been notified of this
permit request. Copies of the letters sent to the property owners and the certified mail
receipts are attached. The signed return receipts from these property owners will be
forwarded to you as soon as possible.
By p -9 f this letter, requests are also made for a Section 401 Water Quality
Cerfi.rication ronl,the North Carolina Division of Water Quality and a Section 404 Permit
fr.,c?r, WcJJ y Corps of Engineers. Please note, a Nationwide Permit No. 3, action
ID # 199303241as previously issued for this project.
+hWyou for your assistance. If you have any questions, please contact Michael
Wood at [phone], Extension 306.
