Wichita, Kan. (AP) -- State regulators have approved a massive expansion at Seaboard Foods' hog feeding operation in western Kansas.
The state is permitting up to 396,000 animals despite concerns from the Sierra Club and others about whether the depleted Ogallala Aquifer underlying it has enough water to treat the waste from that many hogs.
The Kansas Department of Health and Environment signed off on a wastewater permit for the facility on Feb. 26. Its approval was not made public until Tuesday, when the Sierra Club issued a news release criticizing approval of a 50 percent expansion at Seaboard's Ladder Creek facility in Greeley County.
KDHE officials were drafting a response Tuesday afternoon.
Sierra Club cites a recent Kansas Geological Survey report that the aquifer at the site is "effectively exhausted."
