Four years after President Obama ordered new regulatory safeguards to keep politics out of the science behind federal policy, the Environmental Protection Agency still isn’t training its employees on the rules or evaluating their effectiveness.

The agency, which has vast power to reshape the U.S. economy through its environmental regulations, released its proposed version of the safeguards in February 2012, but has since done none of the training required to implement them and hasn’t issued a mandatory annual report on how they are working, according to EPA’s inspector general.
