10 rules that were reinstated

(often following lawsuits and other challenges)


     *Weakened federal rules regulating the disposal and storage of coal ash waste from power plants. A court later ruled the administration was attempting to weaken rules that were not stringent enough.


     *Reversed course on repealing emissions standards for “glider” trucks -- vehicles retrofitted with older, often dirtier engines -- after Andrew Wheeler took over as head of the E.P.A.


     *Delayed a compliance deadline for new national ozone pollution standards by one year, but later reversed course.


     *Suspended an effort to lift restrictions on mining in Bristol Bay, Alaska. But the Army Corps of Engineers is performing an environmental review of an application for mining in the area.


     *Delayed implementation of a rule regulating the certification and training of pesticide applicators, but a judge ruled that the E.P.A. had done so illegally and declared the rule still in effect.


     *Initially delayed publishing efficiency standards for household appliances, but later published them after multiple states and environmental groups sued.


     *Delayed federal building efficiency standards until Sept. 30, 2017, at which time the rules went into effect.


     *Reissued a rule limiting the discharge of mercury by dental offices into municipal sewers after a lawsuit by the Natural Resources Defense Council, an advocacy group.


     *Re-posted a proposed rule limiting greenhouse gas emissions from aircraft, after initially changing its status to “inactive” on the E.P.A. website. In May 2019, the agency confirmed it would issue the rule.


     *Removed the Yellowstone grizzly bear from the Endangered Species List, but the protections were later reinstated by a federal judge. (The Trump administration appealed the ruling in May 2019.)
