Subject: Section 404/40] Individual Permit Modification, Guilford County,
Greensboro Western Urban Loop, from I-85 south of Groometown to
south of I-40 interchange; Federal Aid Project No. STPNHF-NHF-124-
1(1); State Project No. 8.U492101; TIP No. U-2524 AB & AC; USACE

order 8.U492101, WBS Element 34820.1.2
Dear Sir:
As you know, the U.S. Army Corps of Engineers (USACE) issued a Section 404
Individual Permit (IP) to the North Carolina Department of Transportation (NCDOT) to
construct a portion of the Greensboro Western Urban Loop (TIP No. U-2524 AB/AC).
This IP authorizes impacts totaling 1,460 feet of stream, 4.14 acres of wetlands, and 8.62
acres of ponds along the drainages of Long Branch, Reddicks Creek and its unnamed
tributaries, unnamed tributaries of Bull Run, South Buffalo Creek, and Hickory Creek.
The purpose of this letter is to request a modification of the IP for additional stream ~?~ -o
impacts as well as the 401 Water Quality Certification (WQC) for stream and buffer ~-=
impacts from the relocation of a lift station and sewer resulting from construction of thy' ~ I ~'~
road project. The NCDOT also requests a modification of the 401 WQC involving r_.I i "
Condition l4. cJ ---i
Relocation orLift Station and Sewer Line
The proposed relocation of the lift station and sewer lines is needed due to the
construction of the proposed road project. Relocating the sewer lines will involve
temporary impacts a two stream crossings, one at Long Branch and another crossing of an
unnamed tributary of Long Branch. Buffer impacts to Zone 1 and 2 will also result. The
attached permit drawings note the stream impacts with their location section and the

corresponding buffer zone impacts with their section/location. Table 1 summarizes these
impacts.

The NCDOT does not propose any compensatory stream mitigation to
accommodate the sewer line crossings.
The NCDOT has modified the proposed sewer crossings to make the crossings
parallel to the streams. The NCDOT will install pervious brick as a minimization
measure at the lift station in the area noted as Zone 2 buffer.
The NCDOT proposes to mitigate for impacts to the Randleman Buffer by paying
into the NC Wetland Restoration Program. Table 2 summarizes impacts to buffers with
the associated required mitigation ratios.

The total amount of buffer mitigation required for the proposed project is 0.41
acres (17,860 feet2). Based on a cost of 0.96 cents per square foot, the NCDOT will pay
$17, 145.60 to the WRP to provide the necessary buffer mitigation for this project.
Condition 14 of'the 401 WQC
There are several subparts of this condition of the 401 WQC which NCDOT
requests be to modified. The NCDOT would like to modify parts of the first and fourth
notation.

SecCion 404/401 Permit Modification Page 2 of 4
TIP No. U-2524 AB/AC

• Within the first notation, the following statement is found: "The channels must be
allowed to stabilize for an entire growing season."
The NCDOT believes the intent of this statement is for the stream channels to be
stable prior to water being turned into the stream. Typically, new channels are
constructed in the "dry" with a pump around, on new location or with a diversion
channel.
If a pump around is being use, the contractor can only perform construction on the
stream which can be stabilized that day. The new channel must be stabilized, with
matting and/or other measures, by the end of the construction day prior to the contractor
being able to release water into the constructed channel.
The NCDOT believes the condition is not practicable as stated in the 401 WQC.
At the pre-construction review with the NCDOT, the road constuction contractor,
USACE (Mr. John Thomas) and DWQ (Ms. Beth Barnes), it was agreed that water would
not be turned into the relocated channels until the NCDOT had contacted the USACE and
DWQ about reviewing the stream channels instead of waiting an entire growing season to
turn the water into the relocated channels.
Furthermore, at the pre-construction meeting for TIP No. U-2524 AB/AC on
January 6, 2004, the issue of approving stream relocations was discussed. At that time,
Mr. John Thomas of the US Army Corps of Engineers and Ms. Beth Barnes of the
NCDWQ agreed that, after long channel relocations had been constructed and stabilized
with matting, NCDOT Division 7 personnel would contact them for a site visit. At that
site visit, the USACE and NCDWQ would review the stream relocations and, if deemed
stable during the site visit, allow water to be turned to the newly constructed channel.
The fourth notation under this condition involves NCDWQ requiring the NCDOT to
conduct biological monitoring on its relocated channels.
The NCDOT has reviewed the policy noted in the 401 WQC about biological
monitoring. The NCDOT asks that this condition be deleted from the 401 WQC because
all the needed biological monitoring sites have been selected and studied per the eight
eco-regions (per conversation with Mr. Dave Penrose of NCDWQ staff and Mr. Phillip
Todd on November 20, 2003). The NCDOT understands Mr. Dave Penrose of NCDWQ
has sufficient sites for the EPA grant studying biological monitoring and that he has
recently completed the EPA grant funding this review.
The NCDOT asks NCDWQ to debit electronically $475.00 to act as payment for
modifying the 401 WQC as previously noted in this application (see subject line).
In summary, the NCDOT asks the USACE to modify the existing IP for the
Western Greensboro Outer Loop to accommodate the construction of a lift station. The
NCDOT asks the NCDWQ to modify 401 WQC for impacts to streams and buffers and to

about this modification request, please contact Mr. Phillip Todd at [phone].
