Montana is considering setting statewide regulations covering the disposal of radioactive oilfield waste. Currently rules are addressed on a case-by-case basis when landfills are licensed.
The radioactive material is released during fracking for oil and gas. It accumulates in filters used to strain liquids during oil production or in sludge. The proposed rules would increase the amount of radiation allowed per load brought to a landfill. They’re meant to discourage illegal dumping, which has happened in Montana and North Dakota.
