"WASHINGTON - The U.S. Environmental Protection Agency said on Friday it has withdrawn a regulation proposed in the last days of the Obama administration that aimed to tighten health and safety compliance rules for uranium miners.
On Jan. 19, 2017 - a day before Donald Trump took office as president - the EPA had proposed standards to regulate byproduct materials produced by uranium in-situ recovery (ISR) activities, with a primary focus on groundwater protection and restoration.
On Friday, the EPA said existing rules were enough for the protection of public health and safety from radiological and non-radiological hazards associated with uranium and thorium ore processing."
