An oil field waste landfill that withdrew its application to handle radioactive waste was found earlier this year to have tons of illegal radioactive material at its site in McKenzie County.
The state Health Department ordered IHD Solids Management to remove nearly 950 tons of radioactive waste after inspections in May and June at the landfill that’s just south of the Missouri River along Highway 85.
Waste Management Division Assistant Director Steve Tillotson says a third party inspecting group has surveyed the site and that led to the removal of material in the past week.
He says his inspectors now have a new radiation detector that makes it easier to find any improper disposal sites.
Two other oil field waste companies also were found to have illegal materials on site, though in much smaller quantities.
Tillotson says all three operators have changed practices to prevent similar occurrences.
