4h. Explain the purpose of the proposed project:*
As part of the February 25, 2019 Consent Order between North Carolina DEQ and Cape Fear River Watch, Chemours has agreed to treat surface water(s) for PFAS (Per- and
polyfluoroalkyl substances). To assess the base flow conditions, Parsons, working for The Chemours Company, will install temporary flumes in -stream at eight locations. The streams
receive stormwater runoff and groundwater discharge from the adjacent uplands to the west. This study is primary aimed at measuring the groundwater base flow.
41. Describe the overall project in detail, including indirect impacts and the type of equipment to be used:*
Parsons will install eight (8) flumes in the small perennial streams listed below. The flumes will be monitored in 2020 and water flow readings will be acquired. After December 31, 2020
the flumes will be removed, and the area will be restored to preexisting conditions. There Will be no additional fill material placed in wetlands or belowthe ordinary high water mark
(OHWM).
4j. Please upload project drawings for the proposed project.
5. Jurisdictional Determinations
5a. Have the wetlands or streams been delineated on the property or proposed impact areas?*
r Yes
r No
Comments:

of Water Quality stream sheets were prepared. Supplemental information wa attached in the
previous submittal including photographs, maps, and stream sheets.
5b. If the Corps made a jurisdictional determination, what type of determination was made?*
r Preliminary r Approved r Not Verified r Unknown r N/A
Corps AID Number:
5c. If Sa is yes, who delineated the jurisdictional areas?
Name (if known): Luke F. Eggering, SPWS
Agency/Consultant Company: Parsons
Other:
5d1. Jurisdictional determination upload
O Unknown

6. Future Project Plans
6a. Is this a phased project?*
r Yes n No
7b. If yes, explain.
The first phase of this project is to determine the volume of the base flowfrom Chemours (via the eight streams listed) to the Cape Fear River. Subsequent phases will consist of
additional base flow analyses and eventually developing water treatment facilities to remove PFAS as described in the Consent Order (February 25, 2019).
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?
No other NWPs are anticipated.

The flumes will be installed in -stream belowthe OHWM, and they will be monitored during the 2020 sampling period. Thereafter, the flumes will be
removed and all substrate will be graded and restored.
E. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing the project:
There are many seeps emerging from the uplands above the Cape Fear River. The eight identified seep/stream areas were identified to measure
surface water flowto the Cape Fear River. This would minimize the number of potential weirs or flumes necessary to collect the data.
1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques:
Construction will be minimal and will primarily consist of hand tools to ensure that the stream's surface waters flow over and through the flumes to
gather accurate base flow information.
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?
r Yes r No

2b. If this project DOES NOT require Compensatory Mitigation, explain why:
Mitigation will be required during subsequent phases of the Chemours Consent Order development.
NC Stream Temperature Classification Maps can be found under the Mitigation Concepts tab on the Wilmington District's RIBffS website.
F. Stormwater Management and Diffuse Flow Plan (required by DWR)
1. Diffuse Flow Plan
1a. Does the project include or is it adjacent to protected riparian buffers identified within one of the NC Riparian Buffer Protection Rules?
r Yes r No
If no, explain why:
Impacts will be very minimal and temporary.
2. Stormwater Management Plan
