Topeka ? The federal biodefense lab sought by Kansas will need its own electric power and wastewater systems, presumably at state taxpayer expense, state officials said Friday.

The Department of Homeland Security has told states vying for the $451 million National Bio and Agro-Defense Facility to commit to providing dedicated utility plants to keep the lab, which will be handling extremely dangerous substances, self-contained, officials said.

Gov. Kathleen Sebelius said the decision by DHS was a new requirement. She said she would be talking next week with a key DHS leader to determine whether there will be any “additional wrinkles.”

“There was a number thrown out by the feds that we think is just wrong for Kansas,” she said. She said DHS has required that the electric power be gas-generated.

House Speaker Melvin Neufeld, R-Ingalls, said the Legislature will work on a bill to address DHS’ concerns.

Kansas is conducting an all-out press for the facility, which will focus on research related to animal and plant diseases and potential bio-threats to the nation’s food supply.

Six sites, including Kansas State University in Manhattan, are in the running for the lab. Homeland Security is scheduled to pick a location in the fall.

The other sites in contention are Athens, Ga.; San Antonio; Granville County, N.C.; Madison County, Miss.; and an existing lab at Plum Island, N.Y.

DHS spokeswoman Amy Kudwa said a utility plant, much like supporting infrastructure such as land and roads, has been a requirement of the NBAF facility from the start.
