The Environmental Protection Agency has granted DuPont a reissuance of exemption to land disposal restrictions for three Class I hazardous injection wells on their Pontchartrain site in Laplace, Louisiana. DuPont has shown, with a reasonable degree of certainty, there will be no migration of hazardous constituents from the injection zone. The exemption will be valid until December 31, 2050 unless the EPA finds reason to terminate ahead of the expiration date.
Prior to the final decision being made, EPA announced a comment period that was open until October 5. No comments were received and there is no Administrative Appeal.
