Re: Consent Order Paragraph 21 Extension Request Dear Ms. Hughes,
Paragraph 21 of the Consent Order requires that Chemours sample “drinking water wells
for a distance of at least one-quarter (1/4) mile beyond the nearest well with test results showing a quantifiable level of any PFAS listed in Attachment C above 10 ng/L” and that “[s]uch testing shall be completed within eighteen (18) months of entry of this Order.” Pursuant to these requirements in paragraph 21, Chemours has been conducting its Adaptive Step Out and Infill
Sampling Program (the “Sampling Program”), which has involved sampling thousands of drinking water wells at distances of up to fourteen miles from the plant site. Chemours’ extension request letter to DEQ for the sampling of private wells noted that completion of the paragraph 21 sampling program will likely take much of 2021 even though
extension requests can only be considered in 3-month intervals. Chemours previously requested and DEQ approved, pursuant to paragraph 25 of the Consent Order, an extension of 3 months, to February 25, 2021, to complete the Sampling Program. DEQ received the request for extension of the deadline in paragraph 21 of the consent
order from Chemours on February 3, 2021. Therefore, DEQ hereby grants an extension of 3 months, until May 25, 2021 for the company to comply with the requirements of paragraph 21 of the Consent Order.
Sincerely,
Sheila Holman, Assistant Secretary for the Environment
NC DEQ
