A plant in Eastern Carolina is part of a record EPA settlement, for environmental violations.
Invista used to own the now-closed Unifi plant in Kinston, which is part of the DuPont facility on Highway 11.
Invista will pay an estimated $500 million to correct environmental violations at 12 former DuPont facilities in seven states, including in North Carolina. The cleanup is part of a settlement with the Environmental Protection Agency.
Invista will also pay a $1.7 million civil penalty.
Invista self-reported more than 680 pollution violations to EPA after auditing 12 facilities it acquired from DuPont in 2004.
The settlement is the largest in the 14-year history of EPA's audit policy, which provides incentives to companies that voluntarily disclose and correct environmental violations
Invista will reduce harmful air pollution "by nearly 10,000 tons per year," said Catherine R. McCabe, acting assistant administrator of EPA's Office of Enforcement and Compliance Assurance.
Invista manufactures products including Lycra, Stainmaster and Coolmax.
