“When finalized, this action will protect two species of endangered sturgeon and prove to be a boon for commercial and local fishing by also protecting American shad, striped bass and yellow perch,” Zeldin said in a statement.
In order to meet the oxygen levels outlined in the new standards, wastewater facilities would be forced to treat ammonia before discharging into the estuary.
The EPA’s announcement comes as welcome news to the Delaware Riverkeeper Network. The environmental group and scientists have for years urged the Delaware River Basin Commission, which oversees the region’s water quality, to increase its 1967 criteria for dissolved oxygen levels.
In 2022, the riverkeepers petitioned the federal government to step in and take action, which resulted in the EPA’s 2023 proposed standards. However, when the agency did not meet a deadline to finalize those standards, the riverkeepers filed suit in the U.S. District Court for the Eastern District of Pennsylvania.
On Tuesday, the EPA notified the court of its intent to finalize the proposed water quality standards. The Delaware Riverkeeper Network’s Maya van Rossum said the move indicates the EPA is committed to issuing regulations that are “protective of the Delaware River and its aquatic life,” and that “protect sturgeon from extinction.”
Some water providers aren’t as thrilled with the announcement. In a statement on Wednesday, the Philadelphia Water Department said though it agrees water quality standards must be updated, the EPA’s proposal is “overly stringent, not developed with sound science, and could significantly increase PWD customer bills.”
The department said it hopes to work with the EPA on a rule that would improve water quality while also ensuring affordable water rates for customers.
