North Carolina Division of Environmental Management Regulations in 15A NCAC 2H,

waters and wetland areas as described in 33 CFR 330 Appendix A (B} X12} and
General Permit No. 198100049 of the Corps of Engineers regulations (i.e., include any
fill activity for utility line backfill and bedding. This certification replaces Water Quality
Certification Number 2664 issued on January 21, 1992 and is rescinded when the
Corps of Engineers reauthorize Nationwide 12 or Regional Permit 049.
The State of North Carolina certifies that the specified category of activity will
not violate Sections 301, 302, 303, 306 and 307 of the Public Laws 92-500 and 95-
217 if conducted in accordance with the conditions hereinafter set forth.
Conditions of Certification:
1. Activities covered by this General Certification do not require written
concurrence from the Division of Environmental Management DEM} as
long as they comply with all conditions of this General Certification and
the conditions of Nationwide 12 or Regional Permit 049;
2. Written concurrence from DEM is required if the utility line is installed
parallel to and closer than 10 feet ~3 meters} to a stream or if the utility
line crosses a stream channel at less than 75 degrees or more than 105
degrees ~i.e., not perpendicular stream crossing} of the stream bank;
3. Construction corridors parallel to streams shall be placed at the furthest
distance from the stream to the maximum extent practicable;
4. That established sediment and erosion control practices are utilized to
prevent violations of the appropriate turbidity water quality standard X50
NTUs in streams and rivers not designated as trout waters by DEM; 25
NTUs in all salt water classes, and all lakes and reservoirs; and 10 NTUs
in trout waters}. All sediment and erosion control measures placed in
wetlands shall be removed and the natural grade restored after the
Division of Land Resources has released the project;
5. Annual species suitable for wet locations shall be planted within
jurisdictional wetlands for soil and erosion control. Perennials such as
fescue are prohibited;
6. No fertilizer shall be applied within 10 feet ~3 meters} of streams;

7. The construction corridor (including access roads and stockpiling of
materials} is limited to 40 feet (12.2 meters} in width and must be
minimized to the maximum extent practicable.
8. Measures shall be taken to prevent live or fresh concrete from coming
into contact with waters of the state until the concrete has hardened;
9. Permanent, maintained access corridors shall be restricted to the
minimum width practicable and shall not exceed 10 feet (3 meters} in
width except at manhole locations. A 10 feet (3 meters} by 10 feet (3
meters} perpendicular vehicle turnaround must be spaced at least 500
feet (152.4 meters} apart.
10. An anti-seep collar shall be placed at the downstream (utility line
gradient} wetland boundary and every 150 feet (45.7 meters} up the
gradient until the utility exits the wetland for buried utility lines. Anti-seep
collars may be constructed with class B concrete or compacted clay.
Perpendicular wetland crossings less than 150 feet {45.7 meters} long do
not require anti-seep collars.
The com acted clay shall have a specific discharge of 1 X 10"~ cm/sec or
p
less. A section and plan view diagram is attached for compacted clay
and concrete anti-seep collars.
The following specifications shall apply to class B concrete:
a) Minimum cement content, sacks
per cubic yard with rounded
course aggregate 5.0
b) Minimum cement content, sacks
per cubic yard with angular
course aggregate 5.5
c} Maximum water-cement ratio
gallons per sack 6.8
d) Slump range 2" to 4'°
e) Minimum strength - 28 day psi 2,500
11. Placement of rip rap is restricted to stream bottom and banks directly
impacted by the placement of the utility line. The stream berm must be
restored to the original contour after construction;
12. This general certification does not authorize any permanent changes in
preconstruction elevation contours in waters or wetlands. The permittee
will have a specific plan for restoring wetland contours. Any excess
material will be removed to a high ground disposal area;
13. If an environmental document is required, this Certification is not valid

until a FONSI or ROD is issued by the State Clearinghouse;
14. Stormwater management shall not be required for this Certification;
15. Compensatory mitigation (i.e., restoration, creation or preservation} for
wetland losses will not be required far this Certification;
16. This Certification does not relieve the applicant of the responsibility to
obtain all other required or local approval.
Non-campl'rance with or violation of the conditions herein set forth by a specific
fill project shall result in revocation of this Certification for the project.
The Director of the North Carolina Division of Environmental Management may
require submission of a formal application for individual certification for any project in
this category of activity, if it is determined that the project is likely to have a significant
adverse effect upon water quality or degrade the waters so that existing uses of the
wetland or downstream waters are precluded.
Public hearings may be held for specific applications or group of applications
prior to a certification decision if deemed in the public's best interest by the Director of
the North Carolina Division of Environmental Management.
