Dear Mr. Bentley:
Reference your June 21, 1993 application for Department of the Army (DA)
authorization to remove silt which has accumulated in the reservoir basin of
Silt Pond Dam on Blue Ridge Parkway property, located in the headwaters of an
unnamed tributary to Middle Fork Creek, near Blowing Rock, in Watauga County,
Nprth Carolina. The pond has filled in and is currently populated with
rba ous hydrophytes. As a result of the proposed project, approximately
.5 a e of jurisdictional wetlands will be excavated out of the basin in
de to restore the pond to its original condition. In addition, the dam
Cwr
be e
worked on in order to. correct safety deficiencies. This project has
een coordinated with the NC Wildlife Resources Commission (WRC).
For the purposes of the U.S. Army Corps of Engineers' Regulatory Program,
Title 33, Code of Federal Regulations (CFR), Part 330.6, published in the
Federal Register on November 22, 1991, lists nationwide permits (NWP).
.Authorization was provided, pursuant to Section 404 of the Clean Water Act,
for discharges of dredged or fill material into headwaters and isolated
waters.
Your work is authorized by this NWP provided it is accomplished in strict
accordance with the enclosed conditions and provided you receive a Section 401
water quality certification from the North Carolina Division of Environmental
Management (NCDEM). You should contact Mr. John Dorney, telephone (919)
733-1786, regarding water quality certification. This NWP does not relieve
you of the responsibility to obtain other required State or local approval.
This verification will be valid for 2 years from the date of this letter
unless the nationwide authorization is modified, reissued, or revoked. Also,
this verification will remain valid for the 2 years if, during that period,
the nationwide permit authorization is reissued without modification or the
activity complies with any subsequent modification of the nationwide permit
authorization. If during the 2 years, the nationwide permit authorization

-2-
expires or is suspended or revoked, or is modified, such that the activity
would no longer comply with the terms and conditions of the nationwide permit,
activities which have commenced .(i.e., are under construction) or are under
contract to commence in reliance upon the nationwide permit will remain
authorized provided the activity is completed within 12 months of the date of
the nationwide permit's expiration, modification or revocation, unless
discretionary authority has been exercised on a case-by-case basis to modify,
suspend, or revoke the authorization.
Questions or comments may be addressed to Mr. Steve Chapin, Asheville
Field Office, Regulatory Branch, telephone [phone].
