The state Department of Justice announced a settlement Monday over a former Town of Smelser gas station’s clean-up.

William Davis of Galena, the owner of the former D.T. Liquor and Convenience Store at 3019 Highway 80 North north of Cuba City, was fined $7,560 for violating the state’s spills law over contamination of the site.

Davis was also ordered to complete environmental restoration of the site by Jan. 1, 2019. Davis was ordered to pay the fines in installments by Dec. 31, 2021.

Grant County Circuit Judge Robert VanDeHey signed the judgment Nov. 25.

The case dates back to October 2000, when Davis removed four underground storage tanks from the site that contained leaded and unleaded gasoline, diesel fuel and fuel oil. Subsequent soil samples indicated a concentration of diesel fuel 870 times the concentration allowed by state regulation, and a concentration of gasoline 1,000 times what state regulation allows.

In January 2001, the state Department of Natural Resources sent Davis a letter saying he was responsible for restoring the property.

According to case documents, the DNR met with Davis in October 2006, two years after issuing him a Notice of Noncompliance. Davis hired a consultant, but the DNR said in 2007 that the consultant’s work was incomplete.

After the DNR sent Davis letters in 2008, 2011 and March 2012, the DNR then issued two more Notices of Noncompliance. Davis agreed in September 2012 to hire a consultant, but as of Nov. 24 the DNR had not received a site investigation report from Davis or his consultant.

Davis is being required to remove and dispose of contaminated soil, conduct soil and groundwater monitoring at the site, and obtain case closing from the DNR.
