4h. Explain the purpose of the proposed project:*
The purpose of the project is to allow the Town of Wingate (Town) to decommission and remove the existing Diane Street Pump Station and to decommission and abandon in-place the
existing force main that conveys flow from the Diane Street Pump Station to a gravity sewer along May Street that flows to the East Side Pump Station. The pump station and force main
are in need of repairs such that the Town can continue providing reliable sewer service to its customers and protect water quality in the adjacent waterways. The extent and expense of
the necessary repairs are large, and installation of the proposed gravity sewer is a more efficient alternative to replacing or repairing the pump station and force main and will minimize
the service interruption to the existing sewer customers that are currently served by the Diane Street Pump Station and force main.
41. Describe the overall project in detail, including indirect impacts and the type of equipment to be used:*
The project involves the installation of approximately 1,465 feet of 12 -inch sanitary sewer pipe. The proposed pipe will extend from the existing Diane Street Pump Station to a 12 -inch
sanitary sewer line south of the Union County Sheriffs Office. The receiving sewer line is Rays Forks Interceptor. The Diane Street gravity sewer pipe is proposed to be PVC except at
two stream crossings, where the material used will be ductile iron. The Diane Street Pump Station will be decommissioned and removed. A permanent gravel access road will be
constructed to provide future access for maintenance and repair work along the proposed sewer and access to the manhole at Station 1+00 Mich will house an Area -Velocity Meter for
flow monitoring by Union County Public Works Department. To maintain existing drainage patterns within the two streams that cross the proposed sewer corridor, two 30 -inch, reinforced
concrete culverts and a group of three 30 -inch, reinforced concrete culverts will be installed under the proposed access road. Sewage will ultimately be conveyed via the existing East
Side Pump Station to the Monroe Wastewater Treatment Plant for treatment.
No new service connections or service areas will be provided by or supported by the new gravity sewer. No new development will be triggered or supported by the project. Indirect
impacts will therefore be negligible. Equipment anticipated to be used during installation of the gravity sewer include backhoes, front-end loaders, bulldozers, dump trucks, compaction
rollers, flatbed haul trucks, and a pump -around system.

and a larger installation trench. Impacts at S3 and S4 (UT2 to Rays Fork) are associated with a 98 -degree angle crossing of the stream.
E. Impact Justification and Mitigation Q
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing the project:

Avoidance of all impacts is possible with a no -build alternative. The no -build alternative does not meet the need of the project and may result in future
water quality impacts due to the potential for failure of the Diane Street Pump Station and associated force main. A minimum grade in the proposed
pipe is required to maintain gravity flow. In order to connect to the epsting infrastructure at each end of the project while achieving the minimum grade
for gravity flow, the length of the proposed pipe is limited, which narrows the routing options. There is no route that allows for the full avoidance of
stream and wetland impacts while meeting the constraints of the eAsting infrastructure. Prior to and during the design phase of the project, watland
and stream determinations were performed to assess the presence of jurisdictional waters within the proposed pipe corridor. As many components of
the project as is feasible have been sited away from jurisdictional areas. The pipe has been sited to minimize impacts to streams and to be protective
of streams by minimizing the risk of erosion in and around waterways. The permanent access road alignment has been designed to minimize the direct
and indirect impacts to the streams and to the water quality thereof while ensuring access for future repair or maintenance. The culvert length for the
access road crossings of the streams was selected to allow for the road to be adjacent to the pipe alignment and to provide a long enough culvert to
avoid a new aerial sewer crossing.
1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques:
Construction of the transmission line will require traversing two streams. No wetlands will be impacted by the project. Impacts to the streams will be
limited to the extent feasible by performing as much work as is possible from upland areas along the banks of the streams. Installation of the proposed
culverts and coir matting will be performed during dry stream conditions. A temporary pump -around system, including a sediment trap, dewatering
basin, and/or silt bag to minimize introduction of sediment into the downstream reach of the streams, will be utilized to achieve and maintain dry stream
conditions during in -stream work.
A permanent access road is proposed to be installed along the pipe corridor to provide future maintenance and emergency access to the line. The
access road will connect to epsting roadways at each end of the proposed pipeline. The access road crossings of streams will be achieved by the
installation of culverts with bank stabilization measures along the fill slopes and at the inlet and outlet of the culverts. These measures will protect the
stream from future erosion as well as from future impacts from fording the stream to gain access. Best management practices in addition to
sedimentation and erosion control measures will be implemented during all phases of construction. No equipment refueling or maintenance activities
Wil occur adjacent to jurisdictional areas.
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?
C Yes O No

as a result of his operations.
B. For each blast round, Contractor shall monitor and record noise and air blast
overpressures at the site perimeter nearest the blast location and at the on-site or off-
site structure located nearest to the round. Peak air blast overpressure shall not exceed
0.018 psi, measured at the site perimeter.
C. The site of every blast round shall be sufficiently covered with blasting mats or other
devices to prevent any flying debris. The number and type of blasting mats must be
satisfactory to the Engineer. The Contractor will be fully responsible for any damage
caused by flying debris, both to on-site and off-site properties.
D. Whenever blasting is to be performed within 2500 feet of any structure, the Contractor
shall measure the peak particle velocities of ground vibration resulting from each blast at
the structure. Vibrations shall be monitored utilizing a seismograph capable of providing
a record of particle velocity and frequency along three mutually perpendicular axes
utilizing internal calibration. Measured peak particle velocity of ground motion at the
monitored structure shall not exceed the values shown in the following graph:

2. Work Type: ❑Private ❑ Institutional ❑✓ Government ❑ Commercial
3. Project Description / Purpose [PCN Form B3d and B3e]:
The project involves the installation of approximately 1,465 feet of 12 -inch sanitary sewer pipe. The proposed pipe will extend from the existing Diane
Street Pump Station to a 12 -inch sanitary sewer line south of the Union County Sheriffs Office. The receiving sewer line is Rays Forks Interceptor. The
Diane Street gravity sewer pipe is proposed to be PVC except at two stream crossings, where the material used will be ductile iron. The Diane Street
Pump Station will be decommissioned and removed. A permanent gravel access road will be constructed to provide future access for maintenance and
repair work along the proposed sewer. To maintain existing drainage patterns across the proposed sewer corridor, one 18 -inch, reinforced concrete culver
and a arouo of three 30 -inch. reinforced concrete culverts will be installed under the or000sed access road. Sewaae will be conveved via the existina East
