Jennifer,
I would suggest you contact Jonathan McDaniel from Parker and Associates and ask for a detail drawing of the outlet
pipe structure and area. The drawing shows no riprap pad. They do not have in their notes a method of installing the
pipe (i.e. pump around) nor do they mention any temporary impacts for the installation of the pipe (I have found in
working with DOT folks that there is usually a temporary impact due to the fact that they have to over dig to get the pipe
in and down the 12 inches they need for burial.)
You mayjust want to call Jonathan and ask him these questions and just ask him to e -mail you (and me) the drawings
and such.
My suggestion of permit conditions are the following:
1. Wetland Boundary Identification
All wetlands, streams, surface waters, and riparian buffers located within 50 feet of the construction area on the
project site shall be clearly marked (example- orange fabric fencing) prior to any land disturbing activities and must
be maintained on the property until the project phase is completed. [15A NCAC 02H.
2. Any final construction plans for this project must include or reference the application and plans approved
by the Division under this authorization letter and certification. The applicant will also be required to
evaluate all acquired permits to assure that they are consistent and all relative impacts are accounted for
and shown on the construction plans. [15A NCAC 02H .0502 (b) and 15A NCAC 02H .0506 (4)]
Culvert Installation
All work in or adjacent to stream waters shall be conducted in a dry work area. Approved BMP measures from the
most current version of NCDOT Construction and Maintenance Activities manual
(http: / /www.ncdot.org /doh /operations /BMP manual /download /BMP Manual.pdf) such as sandbags, rock berms,
cofferdams and other diversion structures shall be used to prevent excavation in flowing water.
4. Design and placement of the culvert and other structures shall be installed in such a manner that the
original stream profiles are not altered (i.e., the depth of the channel must not be reduced by a widening
of the streambed). Existing stream dimensions (including pattern and profile) are to be maintained above
and below locations of each culvert. The structures shall be designed and installed to allow for fish and
other wildlife movement as well as prevent headcutting of the stream. The applicant may be required to
provide evidence that the equilibrium has been maintained if requested in writing by the NCDWR. [15A
NCAC 02H.0506(b)(2)]
Unless otherwise approved in this certification, placement of culverts and other structures in open waters
and streams, shall be placed below the elevation of the streambed by one foot for all culverts with a
diameter greater than 48 inches, and 20 percent of the culvert diameter for culverts having a diameter
less than 48 inches, to allow low flow passage of water and aquatic life. Design and placement of culverts
and other structures including temporary erosion control measures shall not be conducted in a manner
that may result in dis- equilibrium of wetlands or streambeds or banks, adjacent to or upstream and down
stream of the above structures. The applicant is required to provide evidence that the equilibrium is being
maintained if requested in writing by the NCDWR. If this condition is unable to be met due to bedrock or

other limiting features encountered during construction, please contact the NCDWR for guidance on how
to proceed and to determine whether or not a permit modification will be required. [15A NCAC
02H.0506(b)(2)]
6. If multiple pipes or barrels are required, they shall be designed to mimic natural stream cross section as
closely as possible including pipes or barrels at flood plain elevation and /or sills where appropriate.
Widening the stream channel should 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. [15A NCAC 02H.0506(b)(2)]
7. 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. . All approved rip -rap shall be appropriately keyed in and only placed in wetland and
stream areas that have permitted impacts. [15A NCAC 02H.0506(b)(2)]
8. Natural fiber matting is recommended for streambank stabilization over plastic matting that can entrap
small animals. [15A NCAC 02H .0506(b)(2)]
9. All temporary impacted areas will be restored to pre- construction natural conditions upon completion of
the project. Native vegetation shall be used for wetland and stream bank stabilization. [15A NCAC 02H
.0506 (b)(2) and (c)(2)]
10. All mechanized equipment operated near surface waters or wetlands will be regularly inspected and
maintained to prevent contamination of waters and wetlands from fuels, lubricants, hydraulic fluids or
other potential toxic chemicals. In the event of a hydrocarbon or chemical spill, the permitee /contractor
shall immediately contact the Division of Water Quality, between the hours of 8 am to 5 pm at the
Wilmington Regional Office at 910.796.7315 and after hours and on weekends call (800) 858 -0368.
Management of such spills shall comply with provisions of the North Carolina Oil Pollution and Hazardous
Substances Control Act. [15A NCAC 02H .0506 (b)(3) and (c)(3), 15A NCAC 02B .0200 (3)(f), and GS 143
Article 21A]
11. Fueling, lubrication and general equipment maintenance should not take place within 50 feet of a waterbody or
wetlands to prevent contamination by fuel and oils. [15A NCAC 02H .0506 (b)(3) and (c)(3) and 15A NCAC 02B
.0200 (3)(f)]
12. The permitee shall require its contractors and /or agents to comply with the terms and conditions of this permit in
the construction and maintenance of this project, and shall provide each of its contractors and /or agents associated
with the construction or maintenance of this project with a copy of this Certification. A copy of this Certification,
including all conditions shall be available at the project site during the construction and maintenance of this
project. [15A NCAC 02H .0507 (c) and 15A NCAC 02H .0506 (b)(2) and (c)(2)]
13. Any additional impacts to streams and /or wetlands as a result of future roads, buildings, driveways, utility lines or
other development related activities within this subdivision will require a modification of this 401 Water Quality
Certification approval. [15A NCAC 02H .0506(4) and 15A NCAC 02H .0501 and .0502]
14. Within 60 days of completion of construction, as -built drawings shall be submitted to both the Division of Water
Quality, 401 & Buffer Permitting Unit, 1617 Mail Service Center, Raleigh NC 27699 -1617 and to the Wilmington

Regional Office Division of Water Resources, 127 Cardinal Drive Extension, Wilmington, NC 28405. [15A NCAC 02H
.0507 (c)]
Let me know if you have any questions. So, if you don't have any issues with where they started their stream impacts,
once you get the extra info go ahead and permit it. I am also changing the BIMS permitter to you. Thanks!
