As you know, the purpose of the site visit was to determine the applicability of NPDES industrial stormwater permitting for the Fayetteville Works/industrial park located in Bladen County. I appreciate your time and assistance. As follow-up to the site visit, it was determined that stormwater permit coverage is not applicable based on the following observations. Stormwater flows from industrial activity areas associated with Chemours, DuPont and Kuraray enter surface trenches/culverts and buried pipes (as indicated on the site map that was provided and as observed during the site visit), which convey the stormwater flow to the relocated/current outfall 002 where it is commingled with allowable treated wastewater flows prior to discharge. Outfall 002 is covered under an NPDES wastewater discharge permit and is monitored accordingly. Stormwater flows from the Chemours WX facility and associated access road located in the southwest corner of the industrial park would likely infiltrate into the surrounding vegetated areas. A stormwater ditch that could receive flow from an employee parking area and the access road was observed, however any overflows from this ditch would apparently enter a relatively flat wooded/vegetated area on the property as sheet flow. Regarding the location of the outfall previously identified as outfall 002, which conveys flow to the Cape Fear River. This outfall appears to only receive stormwater flow from the surrounding vegetated area where there is no industrial activity. No other stormwater discharge outfalls were observed. Please note that the determination that NPDES stormwater permit coverage is not required for the subject facility is based on the observations made during the site visit. Should site conditions change such that a point source discharge of stormwater associated with industrial activity is created or discovered, applicable stormwater permit coverage shall be obtained. Please contact me with any questions or concerns.
