A Zachary man must pay a $5,000 fine after being sentenced for illegally dumping gasoline and diesel behind a gas station in Port Allen in 2013.

State Judge J. Robin Free also sentenced Leon Wallace, 58, of Zachary, to two years’ probation and ordered him to pay the state Department of Environmental Quality $970 for the cost of the investigation, according to a press release from DEQ.

Wallace pleaded guilty Feb. 4 in the 18th Judicial District Court.

The sentence stems from an incident on Jan. 25, 2013, when Wallace was loading fuel into his truck at a local refinery and mistakenly mixed several hundred gallons of diesel with several thousand gallons of gasoline already in the tanker truck.

In trying to hide the mistake, Wallace drove to the Super Lucky Louie Casino and dumped some of the mixture at the back of the property, according to DEQ. The contaminated property has been cleaned up.

Wallace was arrested in March 2013, according to DEQ. The case was prosecuted by District Attorney Ricky Ward and Assistant District Attorney Becky Chustz. The 18th Judicial District encompasses West Baton Rouge, Iberville and Pointe Coupee parishes.

Anyone with information about spills, releases, odors, fish kills, open burning, waste tires and any other types of environmental problems may call the department at (225) 219-3640 or toll-free at (888) 763-5424.
