The project will be constructed at a previously undeveloped portion of the property (approximately 3-acres) just west of Bill Hall Road (SR 1304), Adjacent to the William O. Huske Lock and Dam recreational area managed by the U.S. Army Corps of Engineers. Project Contact Information On behalf of Chemours Company FC, LLC: Susan L. Bupp Parsons 2102 Wilson Boulevard Suite 900 Arlington, VA 22201 571 842-6368 (office) 703 598-8492 (cell) Susan.bupp@parsons.com Project Description On February 25, 2019, the North Carolina Superior Court for Bladen County entered a Consent Order (CO) among The Chemours Company FC, LLC (Chemours) and the State of NC and Cape Fear River Watch to address discharges of perfluoroalkyl and polyfluoroalkyl substances (PFAS) at the Chemours Fayetteville Works (the Site). Among other things, the CO required Chemours to develop a remedial plan for reducing PFAS loading from Old Outfall 002 at the Site to the Cape Fear River. Pursuant to paragraph 12.e of the CO, Chemours is required to capture the base or normal stream flow at Location B (as shown in Attachment A of the CO) of Old Outfall 002 (see following site and project location maps) and treat the water prior to discharge into the Cape Fear River. The treatment system for water collected at Location B is required to meet discharge standards set by DEQ and in addition be at least 99% effective in controlling the indicator parameters (i.e., GenX (hexafluoropropylene oxide dimer acid [HFPO-DA]) and perfluoro-2-methoxyacetic acid (PFMOAA)). In order to collect the base flow while allowing stormwater to bypass the system, a concrete weir and overflow structure along with an instream sump will be constructed to capture the base flow from the channel at Location B. Submersible pumps will be installed in the sump to transfer the Sensitive / Proprietary water from Location B to a treatment plant constructed in the upland area to the north (see following detailed site plan). A new road that will provide access to the treatment facility and to the weir will be constructed. In order to allow for variations in the base flow, the capture system will be designed to capture and pump up to the base flow (500 to 1,000 gallons per minute [gpm]). The dam will be equipped with a spillway to allow flows greater than base flow (i.e., stormwater) to bypass the system and continue downstream. Parsons’ preliminary evaluation indicates that the treatment system for captured groundwater would consist of the following unit processes: Equalization (EQ); Chemical precipitation and settling; Filtration; PFAS adsorption (Granular Activated Carbon); Clear well; and Sludge holding and dewatering. An individual Section 404/401 permit is required for the Chemours Fayetteville Works project. Since a U.S. Army Corps of Engineers (USACE) permit under Section 404 of the Clean Waters Act will be obtained, Section 106 consultation is required. The proposed project area is 5 acres. Previous Investigations No cultural resources investigations have been conducted on the Chemours Fayetteville Works property in Bladen County, North Carolina. A Phase I archaeological survey and an architectural study were conducted on several federally owned parcels associated with the Cape Fear locks and dams, including the U.S. Army Corps of Engineers (USACE) recreational area (William O. Huske Lock and Dam) located east of the central portion of the Chemours Fayetteville Works boundary along Glengerry Road (Reed and Botwick 2002; Reed et al. 2003). The Phase I archaeological survey consisted of systematic shovel testing on a 11.7 acre area characterized as upland bluff and river terrace landforms. A low density prehistoric archaeological site (31BL149) was identified on the upland bluff south of the lock keeper’s residence (Reed and Botwick 2002). The site contained 33 artifacts; none were temporally diagnostic. As a result of previous construction and ground disturbance, a low artifact count, and lack of temporal diagnostics, the site was recommended as not eligible for the National Register of Historic Places (NRHP) and no further work was recommended (Reed and Botwick 2002: 44). The William O. Huske Lock and Dam (Cape Fear Lock and Dam 3) was constructed between 1934 and 1935. The lock and dam are made of concrete (Reed et al. 2003). Associated buildings and structures, also constructed in 1935, include the lockmaster residence, the pump house, tool house, hydrant house, garage, tide gage, and tower pedestals (Reed et al. 2003). Modern structures include a 1960s comfort station, picnic shelter, pre-fabricated hazardous materials building, a fuel storage tank, and a corrugated metal storage building. The William O. Huske Lock and Dam was recommended as eligible for listing on the NRHP under Criteria A and C (Reed et al. 2003). The North Carolina State Historic Preservation Office (SHPO) concurred with this recommendation on May 22, 2003 and further stated that the vista of the Cape Fear River from the lock and dam is a vital component of the site setting. Prehistoric Site Probability The proposed project area is located within and north of an intermittent drainage (lower reaches of Old Outfall No. 2) and west of Bill Hall Road. The potential work area is located on a south trending bluff slope above the Cape Fear River (approximately a 15- 20 percent slope) with elevations ranging from 40 feet to 100 feet above mean sea level. Sensitive / Proprietary Limited archaeological investigations have been conducted in Bladen and southern Cumberland counties (Environmental Resources Management [ERM] 2018; Knick 1990). Prehistoric archaeological sites recorded during these two investigations include small lithic and ceramic scatters associated with Archaic (Knick 1990) and Early, Middle, and Late Woodland (ERM 2018; Knick 1990) period occupations. These sites are located on several different types of landforms including along the bluff edges of the Cape Fear River (e.g., sites 31CD2093 and 31CD2096: ERM 2018), near drainage divides (e.g., sites 31CD2097, 31CD2098, and 31CD2119: ERM 2018) and upland areas which may or may not be associated with Carolina Bays (e.g., sites 31CD2094, 31CD2104 and 31CD2105: ERM 2018; site 31BL117: Knick 1990). Most of these sites represent limited occupations with little research potential (only sites 31CD2093 and 31CD2094 require additional evaluation); none have been determined to be eligible for listing on the National Register of Historic Places (NRHP) (ERM 2018; Knick 1990). To date, no prehistoric archaeological sites have been identified on the floodplain or bluff slopes along the Cape Fear River. Although the proposed project area is located adjacent to the Cape Fear River and north of a perennial stream, the area exhibits approximately a 15-20 percent slope and the probability for intact prehistoric archaeological sites with research potential to address NRHP eligibility criteria in the proposed project area is considered low to none. Historic Site Probability Review of historic cartographic maps and archival research was conducted to identify previous land use and provide an assessment of the types of historic archaeological sites that may be anticipated in the proposed project area. In 1938, five occupied residences, one vacant residence, and a business were located along Highway 87; no buildings or structures were identified between the residences along Highway 87 and the Cape Fear River with the exception of the U.S. Lock No. 3 at Tolar Landing (North Carolina State Highway and Public Works Commission 1938). The 1951 aerial photograph depicts the access road to U.S. Lock No. 3 at Tolar Landing and the lockkeeper’s residences and associated structures. An agricultural field or cleared area is located north of Tolar Landing on the floodplain of the Cape Fear River (Nationwide Environmental Title Research [NETR] 1951). The 1961 United States Geological Survey (USGS) Duart quadrangle depicts occupied residences along Highway 87, the access road and lockkeeper’s residences at Tolar Landing (USGS 1961). Dupont purchased the property parcels from several families in 1970 and the first manufacturing area was constructed in the early 1970s. The 1993 aerial photograph depicts the new access road (Glengerry and Bill Hall Roads) to the William O. Huske lock and dam (formerly called U.S. Lock No. 3 at Tolar Landing) (Google Earth 1993). The former access road is still evident but now located with the Fayetteville Works property boundary. Limited archaeological investigations have been conducted in Bladen and southern Cumberland counties (Environmental Resources Management [ERM] 2018; Knick 1990). Historic archaeological sites recorded during these two investigations include late 19th and early 20th century historic debris scatters. Historic artifacts observed included architectural (brick, nails) and domestic debris (glass, whiteware, ceramics, animal bone) (e.g., sites 31CD2097 and 31CD2115: ERM 2018; 31BL117: Knick 1990). These sites represent dispersed scatters with little research Sensitive / Proprietary potential; none have been determined to be eligible for listing on the National Register of Historic Places (NRHP) (ERM 2018; Knick 1990). During the site visit in February 2019, a short segment of a rusted and partially downed fence line was observed. The fence line extended between two trees on bluff edge on the south side of the perennial stream. The fence line segment was constructed of woven wire on the lower portion with a one-strand two-prong barbed wire line above. Based on the archival research and archaeological observation, no historic buildings or structures were located in potential work area the proposed project area; the area south of the perennial stream was fenced by local landowners, prior to the acquisition of the land for the Fayetteville Works. The probability for intact historic archaeological sites with research potential to address NRHP eligibility criteria in the proposed project area is considered low to none. Past Ground Disturbance Although historic aerial photography shows past ground disturbance related to agriculture and timber clearing in some areas of the Chemours Fayetteville Works property, no previous ground disturbance in the proposed project area is evident. Proposed Ground Disturbance Proposed ground disturbance will consist of removing trees and other vegetation, and surface grading/leveling in the following areas: • The entire 3-acre temporary water treatment facility area (including the construction staging area) • Along the access driveway from Bill Hall Road (SR 1304) • Along the maintenance and construction haul road east of the 1-acre temporary water treatment facility area • Along the north bank of Old Outfall No. 2 where the concrete parking pad and pump station will be installed Placement of the effluent pipelines will be on the slope surface and any minimal vegetation removal will be needed to accommodate the pipeline alignment.
