A uranium company launched a concerted lobbying campaign to scale back Bears Ears National Monument, saying such action would give it easier access to the area’s uranium deposits and help it operate a nearby processing mill, according to documents obtained by The Washington Post.

Interior Secretary Ryan Zinke and top Utah Republicans have said repeatedly that questions of mining or drilling played no role in President Trump’s announcement Monday that he was cutting the site by more than 1.1 million acres, or 85 percent. Trump also signed a proclamation nearly halving the Grand Staircase-Escalante National Monument, which is also in southern Utah and has coal deposits.

“This is not about energy,” Zinke said Tuesday. “There is no mine within Bears Ears.”

But the nation’s sole uranium processing mill sits next to the boundaries that President Barack Obama designated a year ago when he established Bears Ears. The documents show that Energy Fuels Resources Inc., a subsidiary of a Canadian firm, urged the Trump administration to limit the monument to the smallest size needed to protect key objects and areas to make it easier to access the radioactive ore.

In a May 25 letter to the Interior Department, Chief Operating Officer Mark Chalmers wrote that the 1.35 million-acre expanse Obama created “could affect existing and future mill operations.” He later noted, “There are also many other known uranium and vanadium deposits located within the [original boundaries] that could provide valuable energy and mineral resources in the future.”

Trump instructed Zinke in April to assess 27 monuments designated under the 1906 Antiquities Act, which gives presidents latitude to protect federal lands and waters under threat. Conservationists, tribal officials, ranching groups and other interests sought to influence the review’s outcome, unsuccessfully in the case of the two Utah sites.
