Attn.: Mr. Dempsey E. Benton

Dear Mr. Benton:
JAN -- 719W
Reference the application of October 29, 1992, submitted on your behalf by
Hazen and Sawyer, for Department of the Army authorization to discharge fill
material within waters of the United States, in association with the
construction of the Neuse River Wastewater Treatment Plant, Expansion and
Upgrade, Phase 3, east of Raleigh, Wake County, North Carolina. You propose
to construct a spill containment area causing the loss of less than 1/3 acre
of an unnamed tributary to the Neuse River, and to construct a structural
terra-gator bridge crossing of the Neuse River requiring bank stabilization.
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
provided:
a. The discharge does not cause the loss of more than 10 acres of waters
of the United States;
b. The permittee notifies the District Engineer if the discharge would
cause the loss of waters of the United States greater than one acre in
accordance with the "Notification" general condition. For discharges in
special aquatic sites, including wetlands, the notification must also include
a delineation of affected specific aquatic sites, including wetlands; and
c. The discharge, including all attendant features, both temporary and
permanent, is part of a single and complete project.
Authorization, pursuant to Section 10 of the Rivers and Harbors Act of 1899
and Section 404 of the Clean Water Act, was also provided for bank
stabilization activities provided:
AF')?
-2-
a. No material is placed in excess of the minimum needed for erosion
protection;
b. The bank stabilization activity is less than 500 feet in length;
c. The activity will not exceed an average of one cubic yard per running
foot placed along the bank below the plane of the ordinary high water mark or
the high tide line;
d. No material is placed in any special aquatic site, including wetlands;
e. No material is of the type or is placed in any location or in any
manner so as to impair surface water flow into or out of any wetlands area;
f. No material is placed in a manner that will be eroded by normal or
expected high flows; and
g. The activity is part of a single and complete project.
Your work is authorized by these NWP provided it is accomplished in strict
accordance with the enclosed conditions. These NWP do not relieve you of the
responsibility to obtain any required State or local approval.
This verification will be valid for 2 years from the date of this letter
unless the NWP authorization is modified, reissued, or revoked. Also, this
verification will remain valid for the 2 years if, during that period, the NWP
authorization is reissued without modification or the activity complies with
any subsequent modification of the NWP authorization. If during the 2 years,
the NWP authorization expires or is suspended or revoked, or is modified, such
that the activity would no longer comply with the terms and conditions of the
NWP, activities which have commenced (i.e., are under construction) or are
under contract to commence in reliance upon the NWP will remain authorized
provided the activity is completed within 12 months of the date of the NWP'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. Eric Alsmeyer, Raleigh
Regulatory Field office, at telephone [phone], extension 23.
Sincerely,
G. Wayne Wright

Subject: Proposed Fill in Wetlands or Waters
Spill containment facility
Wake County
DEM Project #92652
Upon review of your request for Water Quality Certification
to place fill material in less than one-third acre of wetlands or
waters for spill containment facility located at Raleigh
wastewater treatment plant in Wake County, we have determined
that the proposed fill can be covered by General Water Quality
Certification No. 2671 and 2745 issued January 21, 1992. A copy
of the General Certification is attached. This Certification may
be used in qualifying for coverage under Corps of Engineers'
Nationwide Permit No. 25 and 26.
If you have any questions, please contact John Dorney at
919/733-1786 or 919/733-1787.

Re: Neuse River Wastewater Treatment Plant
Proposed Spill Containment Area and
Proposed Terra-Gator Bridge
Over Neuse River
H&S No. 3971
Dear Mr. Alsmeyer:
Attached for your review are preliminary Drawings and construction
procedures for the above referenced projects. We request construction approval of
these projects based on satisfaction of the permit requirements of Section 404 of
the Clean Water Act. As you discussed with Mr. Chris Phillips and Mr. Alan Stone
of Hazen and Sawyer on Wednesday, October 21, 1992 at the job site, we request
approval under nationwide permit No. 26 for the proposed spill containment area
and nationwide permit No. 25 for the proposed Terra-Gator bridge to satisfy the
Section 404 permit requirements.
The spill containment area is being built to help prevent any harmful waste
from being discharged into the Neuse River. If any kind of waste or chemical were
spilled into the plant's storm drainage system, the waste could be captured in the
spill containment area. A preliminary construction plan of the spill containment
area is included as Attachment No. 1. The total area disturbed is less than 1 /3
acre.
The Terra-Gator bridge is proposed to gain access to sludge application fields
located across the Neuse River from the wastewater treatment plant without using
public roads. The proposed bridge is as a low-water bridge designed to be
inundated during a 10-year plus storm event. Recent HEC-2 analyses by Hazen
and Sawyer indicate that the bridge will not cause a rise in flood elevation at the
bridge for the 100-year event. A preliminary General Drawing of the bridge is
included as Attachment No. 2 and the construction sequence for the bridge is
included as Attachment No. 3. The proposed construction sequence is based on a
New York, NY - Armonk, NY - Upper Saddle River, NJ - Raleigh, NC - Charlotte, NC - Richmond, VA - Hollywood, FL - Boca Raton, FL - Fort Pierce, FL - Jupiter, FL - Miami, FL - Bogota, D.E. Colombia

substructure using HP12X53 piles encased in concrete to a depth of 18" below the
river bed. A subsurface investigation is currently in progress to determine if
bedrock is at a sufficient depth below the riverbed to allow sufficient penetration
of the HP12X53 piles to develop adequate lateral stability. If bedrock is too
shallow, the interior support piers will be supported on concrete piles battered as
necessary to resist the lateral loads. This alternative will not require construction
of a pile encasement. Therefore, a coffercell will not be constructed, and
nationwide permit No. 25 will probably not be applicable. We will advise when
this decision is reached.
By copy of this letter I am transmitting the referenced attachments to Mr.
John Dorney of DEM requesting a 401 Water Quality Certification. We understand
that the general 401 certification to be issued by DEM is for work required under
nationwide permits 26, 25 and 13. The total length of stream bank stabilization is
less than 500 linear feet. We further understand that written application to DEM is
not required but we are providing them this information for their records.
Please advise if further information is needed or if additional permits are
required.
Very truly yours,
HAZEN AND SAWYER, P.C.
