All three have been stalled by successful legal challenges by environmental groups alleging the administration failed to apply the regulatory scrutiny required under the law.
The Republican administration tried to accelerate permits for two multi-billion-dollar natural gas lines and jumpstart the long-stalled Keystone XL crude oil pipeline that would start in Canada. Judges halted construction on all three over the past two years, ruling that the administration granted permits without conducting adequate studies or providing enough alternatives to protect endangered species or national forests.
