regulations. Also this approval will expire when the accompanying 404 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. If you change your project, you must
notify us in writing 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 the 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). For this approval to be valid, you must follow the conditions listed in the attached certification and the additional condition listed
below:
1. Upon completion of all work approved within the 401 Water Quality Certification or applicable Buffer Rules, and any subsequent
modifications, the applicant is required to return the attached certificate of completion to the 401/Wetlands Unit, North Carolina
Division of Water Quality, 1650 Mail Service Center, Raleigh, NC, 27699-1650;
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 which conforms to Chapter 1508 of the North Carolina
General Statutes to the Office of Administrative Hearings, 6714 Mail Service Center, Raleigh, N.C. 27699-6714. This certification and its
conditions are final and binding unless you ask for a hearing.

Re: Pre-Construction Notification Application Form
Submittal for the City of Graham - Section 404 Permit and
401 Water Quality Certification Processing
for Stream Crossings at the Haw River and Back Creek
Alamance County, North Carolina
Dear Mr. Dorney:
AMEC Earth and Environmental, Inc. of North Carolina (AMEC) is pleased to submit this Pre-
Construction Notification (PCN) Application Form for the City of Graham for stream crossings at
the Haw River and Back Creek in Alamance County, North Carolina. The project is located
approximately 2.5 miles southeast of Graham.
The project consists of two stream crossings at Hwy 54 for the installation of a water supply
system for the City of Graham. The stream crossing construction will involve trenching for the
installation of a 12-inch water line to an approximate depth of 3 feet beneath the stream
channels and installation of concrete thrust ring restraints along the stream banks. Impact to the
Haw River will be 100 linear feet. Impact to Back Creek will be 50 linear feet.
Alternate design involving the use of existing bridges for pipe suspension was originally
proposed for this project but rejected by NCDOT and therefore not an option.
Seven copies of the PCN are enclosed for your review and the $475 fee is attached. Please do not
hesitate to contact me if you should have any questions or comments.
Sincerely,
AMEC Earth and Environmental, Inc. of North Carolina

VIII. Mitigation
DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on March 9, 2000, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.
If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCWRP concurrence shall be placed on hold as
incomplete. An applicant may also choose to review the current guidelines for stream restoration
in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at
http:Hh2o.enr.state.nc.us/newetlands/strm;;ide.html.
1. Provide a brief description of the proposed mitigation plan. The description should provide
as much information as possible, including, but not limited to: site location (attach directions
and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet)
of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view,
preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a
description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed.
No mitigation tier NWP12 conditions.
