Re: Consent Order Paragraph 19 Extension Request

Dear Ms. Hughes,

Paragraph 19 of the Consent Order states that “Chemours shall establish and properly
maintain permanent replacement drinking water supplies in the form of public water or whole
building filtration system for any party (household, business, school, or public building) with a
private drinking water well that has been found through testing validated by the North Carolina
Department of Environmental Quality (DEQ) to be contaminated with concentrations of GenX
compounds in excess of 140 ng/L, or any applicable health advisory, whichever is lower.”

DEQ issued a response letter to Chemours regarding the feasibility of municipal water in
Bladen County west of the Cape Fear River while areas in Cumberland County west of the river
continue to be evaluated. Paragraph 25 of the Consent Order states, “For good cause shown,
Chemours may submit to DEQ one or more requests for extensions of up to three months each
for any deadline specified in paragraphs 19-24.

By a letter dated December 14, 2021, DEQ granted such an extension to March 15, 2022,
for Chemours to meet the paragraph 19 requirements in Bladen and Cumberland Counties west
of the Cape Fear River. On March 7, 2022, Chemours requested, pursuant to paragraph 25 of the
Consent Order, a further extension of 3 months to meet the paragraph 19 requirements. DEQ
hereby grants an extension of ninety days, until June 15, 2022 for the company to comply with
the requirements of paragraph 19 of the Consent Order.

Sincerely,

Sushma Masemore, PE
Assistant Secretary, NC DEQ
