Colorado, along with 15 other states, is poised to sue the federal government for ignoring endangered species regulations in a wide range of infrastructure projects on public lands. One of those projects, a controversial proposal to expand an oil shipping facility in Utah, would significantly increase hazardous rail shipments through Colorado.
Phil Weiser, Colorados attorney general, and the attorneys general of the other states provided in a July 18 letter to Trump administration officials a 60-day notice of their intent to sue. The notice expired last week.
The letter cites violations of the Endangered Species Act it says have occurred in pursuit of an executive order, called Declaring a National Energy Emergency, which President Donald Trump signed on his first day in office in January.
The ESA and implementing regulations do not allow agencies to routinely avoid and delay implementation of the ESAs protections of endangered species and their critical habitats in the manner you have directed and which your agencies are carrying out, the letter says.
