Three executives charged in a chemical spill last January in West Virginia have pleaded not guilty.
Former Freedom Industries officials Dennis Farrell, William Tis and Gary Southern entered pleas Thursday in front of U.S. Magistrate Judge Dwane Tinsley in Charleston.
Farrell and Tis were released on $10,000 bonds.
Southern posted a $100,000 bond in a Fort Myers, Florida, federal court Dec. 9. He was arrested Dec. 8 on a criminal complaint from an FBI affidavit.
Their trials are scheduled for March 10 in Charleston.
Tinsley also ordered Southern to surrender his private pilot's license.
Six former Freedom officials and Freedom itself face pollution charges. Southern also faces fraud charges related to Freedom's bankruptcy case.
The spill spurred a tap-water ban for 300,000 people for days.
