Hanes Mill Road, Suite 300 Winston-Salem, NC 27105 Re: Erwin 230kV-Buies Creek Switch Harnett County, NC Ms. Homewood: ESI is serving as the environmental consultant for this Duke Energy project. I am submitting the enclosed information in response to your email to Mr. Thomas Williams on June 4, 2019. The project engineering team has reviewed your request and is proposing to use a pump around method to be able to work in the dry while the road crossing culvert is installed. A schematic and sequence of this process is included herein. Additionally, the pump around method is not anticipated to result in any additional permanent or temporary impacts. The engineer states that the upstream dam location for the pump around will coincide with the upstream inlet protection location for the culvert. I have included a copy from the erosion control plan prepared by the engineer. I trust that this additional information will provide you with the necessary information to continue your review of the 401 WQC request. Please let me know if you have any further questions or if I can be of any assistance.

The contractor should stay wnthin the limits of the disturbance as shown on the plane and minimise disturbance within the work area whenever possible. 2 IIpon installation of all sediment control measures and approval by the sediment contra] Inspector, the contractor should begin work at the upstream section and proceed downstreem beginning with the establishment of stabilized construction eatrenom.

York should not be conducted in the channel during rem event.. 3 Sandhog dikes should be situated at the upstream and downstream ends of the work area as shown on the plans, and stream flow should be pumped around the work Area. The pump should discharge onto a stable velocity dissipater made of riprap. 4 Excavated topseD and subsoil should be kept separate, placed on the upland side of the excavation, and replaced in their natural order. 5 All construction should take place during stream low flows. The length of construction time should be limited to a maximum of 2 days for each erossing. 8 Water from the work area should be pumped to a dewatering bag as shown in detail 3.25. The measure should be located such that the water drains hack into the channel below the downstream sandbag dike. 7 Traversing a channel reach with equipment within the work area where no work is proposed should be avoided.
