Robb,
Attached is our response to your email requesting additional information specific to how the soils within the wetland
crossings would be handled during construction of the proposed gravity sewer. Please let me know if you have any
questions, or if you require any additional information to complete your review.
Have a great weekend.

Hey Troy,
1

Hope all is well. I am reviewing this application for the 401 Cert. and was checking to see if you could provide a typical
cross-section for the proposed sewer line in relation to the existing wetlands. Also, can you include how the soils will be
handled and separated during the excavation and the replacement process. Attached is an example of what we'll need.
Thanks and hope you have a good weekend,
RM

Dear Mr. Mairs
This letter is in response to your email, dated 09/29/17, requesting additional information for the
NWP 12 PCN for the Beau Coast - Gravity Sewer project in the Beau Coast subdivision (formerly
Beaufort East Village) in Beaufort, Carteret County.
In your email you requested:
• Please provide a typical cross-section for the proposed sewer line in relation to the existing
wetland. Also, please include how the soils will be handled and separated during the excavation
and replacement process in order to address GC 4086 Activity Specific Conditions #7.
As shown in the "Typical Buried Gravity Sewer Main Wetland Crossing Detail", the topsoil and
subsoil will be separated into separate stockpiles, which will be placed on fabric where possible.
The trench will be backfilled with subsoils, and the subsoils will be compacted prior to placing
the topsoil back in the trench.
Please feel free to call if you have questions or require additional information.
Sincerely
WithersRavenel
Troy Beasley
Senior Environmental Scientist

1. THE MIXING OF TOPSOIL AND SUBSOILS ALONG HEADER LANES AND GRAVITY SEWER
MAINS WITHIN WETLAND AREAS SHALL BE MINIMIZED TO THE GREATEST EXTENT
PRACTICAL. TOPSOIL EXCAVATED FROM PIPE TRENCHES WILL BE PILED SEPARATELY
FROM SUBSOILS AND WILL BE BACKFILLED INTO THE PIPE TRENCH ONLY AFTER ALL
SUBSOILS HAVE BEEN PLACED AND COMPACTED.
2. GENERAL STRIPPING OF TOPSOIL ALONG THE GRAVITY SEWER EASEMENT IS NOT
PERMITTED.
3. ALL PERISHABLE MATERIALS INCLUDING TREES, STUMPS AND LARGE ROOTS SHALL BE
REMOVED WITHIN THE CLEARED AND GRUBBED AREA. NO STUMPS OR OTHER WOODY
GROWTH WILL REMAIN IN THE CLEARED AREA FINE LITTER SUCH AS PINE NEEDLES,
SMALL TWIGS, ETC. SHOULD BE LEFT WHERE POSSIBLE AS A MULCH TO PROTECT THE
SOIL.
4. DISTURBED WETLANDS WITHIN SEWER CORRIDOR WILL BE PLANTED WITH A WETLAND
SEED MIX AS SPECIFIED IN PLANTING DETAILS IN CONSTRUCTION PLANS.
