Last November, the Environmental Protection Agency said it would rescind a rule that banned companies from fitting outdated, older, and dirtier diesel engines into brand-new "glider" chassis-cab trucks. Among the many regulations to limit emissions and other forms of pollution that EPA administrator Scott Pruitt has axed, this one was particularly...
