Dear Mr. Swain:
You have our approval, in accordance with the attached conditions and those listed below, for the following impacts in
an unnamed tributary to the Catawba River, for the purpose of constructing a turn lane at Catawba Meadows Park on US
Highway 64 (Sanford Road) in Burke County:
Stream Impacts in the Catawba River Basin
Site Permanent Temporary Fill in Permanent Fill in Temporary Total Stream Stream
Fill in Intermittent Stream Perennial Stream Dewatering in Impact Impacts
Intermittent (linear ft) (linear ft) Perennial Stream (linear ft) Requiring
Stream (linear (linear ft) Mitigation
ft linear ft
Site 1 Sta. 0 0 20 30 50 0
2+50
Total 0 0 20 30 50 0
Total Stream Permanent Impact for Project: 20 linear feet. Temporary Impact for Project: 30 linear feet.
The project should be constructed in accordance with your application dated June 2, 2008 (received June 6, 2008),
including the environmental commitments made in the application letter. After reviewing your application, we have
decided that these impacts are covered by General Water Quality Certification No. 3704, corresponding to the U.S. Army
Corps of Engineers Nationwide Permit Number 14. In addition, you should acquire any other federal, state or local
permits before you proceed with your project including (but not limited to) Sediment and Erosion Control, Non-
Discharge and Water Supply Watershed regulations.
This approval is valid solely for the purpose and design described in your application (unless modified below). Should
your project change, you must notify the DWQ and submit a new application. 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, or if total impacts to streams (now
or in the future) exceed 150 linear feet, 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 and any
additional conditions listed below.

1. There shall be no excavation from or waste disposal into, jurisdictional wetlands or waters associated with this
permit without appropriate modification. Should waste or borrow sites, or access roads to waste or borrow sites, be
located in wetlands or streams, compensatory mitigation will be required since that is a direct impact from road
construction activities.
2. Sediment and erosion control measures shall not be placed in wetlands or waters unless otherwise approved by this
Certification. If placement of sediment and erosion control devices in wetlands and waters is unavoidable, they shall
be removed and the natural grade restored upon completion of the project.
3. Adequate sedimentation and erosion control measures must be installed and maintained on the project site to
minimize sediment transport to downstream aquatic resources. Temporary cover (wheat, millet or similar annual
grain) or permanent herbaceous cover shall be planted on all bare soil within 15 working days of ground disturbing
activities. Erosion control mating shall be used in conjunction with appropriate seeding on disturbed soils in steep
slope and riparian areas. Steep slopes are defined as those slopes graded at an angle, which cannot retain vegetative
cover. Matting shall be secured in place with staples or wherever possible. Matting should be secured in place with
staples or wherever possible, live stakes of native trees. Straw mulch and tall fescue shall not be used in riparian
areas.
4. If multiple pipes or barrels are required, they shall be designed to mimic the natural stream cross section as closely as
possible including pipes or barrels at flood plain elevation and/or sills-where appropriate. Widening the stream shall
be avoided. Stream channel widening at the inlet or outlet end of structures typically decreases water velocity
causing sediment deposition that requires increased maintenance and disrupts aquatic life passage.
5. For projects impacting waters classified by the NC Environmental Management Commission as Trout Jr), High
Quality Waters (HQW) or Water Supply I or II (WS-1, WS-II), stormwater shall be directed to vegetated buffer
areas, grass-lined ditches or other means appropriate to the site for the purpose of pre-treating stormwater runoff
prior to discharging directly into streams. Mowing of existing vegetated buffer areas is strongly discouraged.
6. Native riparian vegetation (e.g. rhododendron, dog hobble, willows, alders, sycamores, dogwoods, black walnut and
red maple) must be reestablished within the construction limits of the project by the end of the growing season
following completion of construction.
7. The use of riprap above the Normal High Water Mark shall be minimized. Any riprap placed for stream stabilization
shall be placed in stream channels in such a manner that it does not impede aquatic life passage.
8. Riprap shall not be placed in the active thalweg channel or placed in the streambed in a manner that precludes
aquatic life passage. Bioengineering boulders or structures should be properly designed, sized and installed.
9. Heavy equipment shall be operated from the banks rather than in the stream channels in order to minimize
sedimentation and reduce the introduction of other pollutants into the stream.
10. All mechanized equipment operated near surface waters must be regularly inspected and maintained to prevent
contamination of stream waters from fuels, lubricants, hydraulic fluids, or other toxic materials.
11. The Permittee shall ensure that the final design drawings adhere to the permit and to the permit drawings submitted
for approval.
12. Discharging hydroseed mixtures and washing out hydroseeders and other equipment in or adjacent to surface waters
is prohibited.
13. No rock, sand or other materials shall be dredged from the stream channel, except where authorized by this
certification.
14. All fill slopes located in jurisdictional wetlands shall be placed at slopes no flatter than 3:1, unless otherwise
authorized by this certification.
15. The outside buffer, wetland or water boundary located within the construction corridor approved by this
authorization shall be clearly marked by highly visible fencing prior to any land disturbing activities. Impacts to
areas within the fencing are prohibited unless otherwise authorized by this certification.
16. A copy of this Water Quality Certification shall be maintained on the construction site at all times. In addition, the
Water Quality Certification and all subsequent modifications, if any, shall be maintained with the Division Engineer
and the on-site project manager.

17. The issuance of this certification does not exempt the Permittee form complying with any and all statutes, rules,
regulations or ordinances that may be imposed by other government agencies (i.e. local, state, and federal) having
jurisdiction, including but not limited to applicable buffer rules, stormwater management rules, soil erosion and
sedimentation control requirements, etc.
18. The permittee and its authorized agents shall conduct its activities in a manner consistent with State water quality
standards (including any requirements resulting from compliance with §303(d) of the Clean Water Act) and any
other appropriate requirements of State or Federal law. If DWQ determines that such standards or laws are not being
met (including failure to sustain a designated or achieved use) or that State of Federal law if being violated, or that
further conditions are necessary to assure compliance, DWQ may reevaluate and modify this certification.
19. The Permittee shall report any violations of this certification to the Division of Water Quality within 24-hours of
discovery.
20. Upon completion of the project, the NCDOT Division Engineer shall complete and return the enclosed "Certificate of
Completion Form" to notify NCDWQ when all work included in the §401 Certification has been completed. This
form shall be returned to the Transportation Permitting Unit of the NC Division of Water Quality, 2321 Crabtree
Blvd., Suite 250, Raleigh, North Carolina 27604.
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 150B 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.
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 Mr. Mike Parker of the Asheville Regional Office at 828.296.4500.
