surrounding area as well as a construction laydown/staging area located in a maintained upland area within the water treatment plant property. The reach of the Tar River in which the
project is located is highly susceptible to sand deposition. The vicinity of the project site is currently developed for residential and commercial uses as well as undeveloped areas and
agricultural lands. Additionally, the Pitt -Greenville Airport is located east of the project site.
4b. Have Corps permits or DWR certifications been obtained for this project (including all prior phases) in the past?
Yes No Unknown
If yes, please give the DWR Certification number or the Corps Action ID (exp. SAW-0000-00000).

4f. List the total estimated acreage of all existing wetlands on the property:
0.87 acre
4g. List the total estimated linear feet of all existing streams on the property:
1,850feet
4h. Explain the purpose of the proposed project:*
The purpose of the proposed project is to restore the original, designed capacity to the GUC Water Treatment Plant (WTP) raw water intake screens, which are being severely
compromised by ongoing sand deposition. These intake screens constitute the sole source of raw water to the City of Greenville. Sediments have collected around the intake screens and
will be removed to restore full operational capacity of the intake while significantly reducing the risk of severe damage to the raw water pumps due to sand being drawn into the pump
station. Maintenance dredging will ensure that the flow of water in the river to the screens provides adequate volume. Recent assessments of the sediment deposition around the screens
indicate that accumulated sand covers up to 50 percent of the intake openings of the upstream screens and two of the four downstream screens. The other two downstream screens are
covered from 65 to 100 percent, resulting in a reduction in overall capacity by approximately 50 percent. Additionally, sand is accumulating in the wetwells of the pump station, with up to
30 cubic yards of sand in one wetwell, which poses a danger of further damaging the pump internals. Maintenance dredging for this purpose is an ongoing need and a routine operation.
4i. Describe the overall project in detail, including indirect impacts and the type of equipment to be used: *
The maintenance dredging involves removal of accumulated sediments and debris within the area surrounding the upstream and downstream intake structures. The area identified for
maintenance dredging around the upstream intake structure is anticipated to extend 135 feet upstream and 65 feet downstream from the structure and 80 feet across the river, at a
maximum. The downstream extent of dredging is needed to prevent against movement of the sediments in the near future to a position in which the downstream intake screens will be
similarly blocked. The area identified for maintenance dredging around the downstream intake structure is anticipated to extend 170 feet upstream and 30 feet downstream from the
structure and 75 feet across the river.
The maintenance dredging extents are the minimum area needed at a given time to maintain adequate flows to the intake screens. The depth of the dredging will not be deeper than the
approximate channel depth that existed when the intake screen clusters were originally constructed, as documented on record drawings for the intake screen clusters, attached. Dredging
around the intake structures will be performed using a hydraulic dredge operated by a diver in the river to ensure that the existing infrastructure and aquatic life are not damaged or harmed
by the work. Dredging beyond the area immediately surrounding the intake structure will be performed via mechanical dredge.
Dredged materials will be temporarily stockpiled onsite in an upland area. Dewatering will occur via passive methods, including evaporation and infiltration. Silt fence will be installed
around the perimeter of the temporary stockpile area to protect against erosion and unintended transport of dredged materials beyond the limits of the stockpile area. The dredge spoils will
be hauled offsite for disposal at an approved landfill.
Land -based site access will be accomplished across existing onsite access roads and maintained lawn areas. No disturbance of existing wetlands, streams, floodplain, floodway, or
riparian buffer vegetation is anticipated to occur to accommodate site access. Sediment control within the river will be in the river for the duration of the dredging operation. The specific
measure to do so will be selected by the contractor and shall require approval by the engineer and GUC. The measure must contain suspended sediments within the work area, preventing
downstream water quality degradation.
5. Jurisdictional Determinations
5a. Have the wetlands or streams been delineated on the property or proposed impact areas? *
Yes
No
Comments:
Waters of the US were delineated and verified in 2016. Re -delineation was performed but not verified

6. Future Project Plans
6a. Is this a phased project?*
Yes 0 No
O Unknown

6b. If yes, explain.
In 2022, dredging of the downstream screen area was submitted for authorization under the Clean Water Act. The issued 401 certification authorized the entire proposed activity (0.28 acre
of dredging). The issued 404 permit was reduced due to delays with interagency coordination. The issued 404 permit authorized the minimum dredging effort needed to ensure adequate
water supply be available to the City of Greenville through the 2023 Atlantic sturgeon moratorium period.
Via this PCN, GUC requests a slightly larger area adjacent to the downstream screens and the area around the upstream screens be authorized to be dredged as maintenance activities to
support future operation of the raw water intake.
Are any other NWP(s), regional general permit(s), or individual permits(s) used, or intended to be used, to authorize any part of the proposed project or related activity?
0.28 acre of impact associated with the downstream screen dredging was previously authorized under DWR 20090266 v9 in October 2022. This work has not been completed in its
entirety and will be relied upon for impact OW-1 shown herein.

NOTE - OW-1 was previously authorized by DWR under 20090266 v9 and is not requested for reauthorization from DWR. OW-1 was authorized in part
by USACE under SAW-2018-01462; the USACE-authorized portion of the dredging was completed in early 2023 and will be repeated due to
redeposition of sand from abutting areas.
E. Impact Justification and Mitigation O
1. Avoidance and Minimization
la. Specifically describe measures taken to avoid or minimize the proposed impacts in designing the project:
Avoidance of impacts to waters of the US is only possible with a no -action alternative, which does not address GUC's responsibility to continue providing
adequate drinking water to their customers. The nature and extent of the proposed impacts are the minimum necessary to ensure that GUC is able to
fulfill their responsibility to their customers for the near future. The proposed impacts are in the area of previous impacts associated with establishing and
maintaining the intake screens, avoiding areas that have not been previously disturbed. Laydown and site access footprints utilize existing
maintained/disturbed areas, avoiding impacts to wetlands, riparian buffers, and undisturbed natural areas.
1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques:
All equipment used for in -water work will be mounted on a barge in the river, eliminating potential damage to the riverbank and temporary impacts to
adjacent wetlands. The laydown area will be established in an upland area away from the riparian buffer. Vehicle and equipment maintenance will be
performed away from sensitive resources in order to protect these areas from spills or leaks of fluids. In -river sediment control measures will be used to
contain sediments that are disturbed during construction. A vac truck or other temporary pump method will be used to remove the suspended sediments
and dredged materials from the river. The work will be performed using divers in order to protect the river and its inhabitants from avoidable effects. The
time -of -year restriction that is applicable to in -water work in the Tar River at Greenville will be complied with in order to provide protection to aquatic
species.
2. Compensatory Mitigation for Impacts to Waters of the U.S. or Waters of the State
2a. Does the project require Compensatory Mitigation for impacts to Waters of the U.S. or Waters of the State?
