“I am disappointed that the seven Basin States could not reach a consensus agreement on the future management of the Colorado River by the U.S. Department of the Interior’s Feb. 14 deadline. In the spirit of compromise, the Upper Basin States, including Colorado, recently offered a revised proposal that closely followed a plan recommended by the Interior Department. The Lower Basin rejected that plan, did not offer an alternate proposal, and walked away from the table before the deadline. “Colorado will continue to work with our fellow Upper Division States to provide comments on the federal government’s draft environmental impact statement, which sets forth a range of possible solutions. The Upper Division States will have to cut back their usage of water from the Colorado River—by 40 percent or more—in the face of an historic drought. Colorado is prepared for any litigation, and we will work tirelessly to protect our state’s rights and interests under the Law of the Colorado River.”

Attorney General Phil Weiser statement on U.S. EPA revoking a key policy to combat climate change: “In the action announced today, EPA has finalized its misguided proposal to rescind the endangerment finding. As I explained in my testimony to EPA on the proposal, there is no legal or scientific justification to roll back decades of progress in fighting climate change by undoing a finding rooted in well-established research and common sense: greenhouse gas emissions from motor vehicles endanger public health and welfare. We live that reality every day in Colorado, with record drought, catastrophic wildfires, and ever-increasing heatwaves that threaten our residents, economy, and infrastructure. The Supreme Court held nearly 20 years ago that the federal Clean Air Act authorizes EPA to regulate greenhouse gas emissions. I will challenge this illegal action in court.”

Colorado did not receive advance warning or time to prepare, the timeline would have been impossible to meet, and the state faced removal from the SNAP program if it did not comply. “This was not a real pilot project. It was punishment from the Trump administration and Agriculture Secretary Rollins who disagree with our mail in ballot elections and how we carry out our state criminal justice system. The administration cannot punish Colorado into submission, and I’ll continue to fight back when the federal government harms Colorado and acts like it’s above the law." coag.gov
