Congressional Budget Office Cost Estimate: H.R. 3053: Nuclear Waste Policy Amendments Act of 2017 [open pdf - 113KB]
"Under the Nuclear Waste Policy Act (NWPA), the federal government, through the Department of Energy (DOE), is responsible for permanently disposing of the nation's nuclear waste in a geologic repository at Yucca Mountain, Nevada. H.R. 3053 would not change that fundamental requirement, but would temporarily limit DOE's authority to collect certain fees charged to utilities with nuclear plants to cover the costs of disposing of the waste they generate and would authorize DOE to enter into agreements to provide benefits to state, local, and tribal governments that might host or be affected by facilities related to the waste management program."
