60. Overturned a ban on the use of lead ammunition and fishing tackle on federal lands.
61. Overturned a ban on the hunting of predators in Alaskan wildlife refuges.
62. Amended fishing regulations to loosen restrictions on the harvest of a number of species.
63. Proposed revising limits on the number of endangered marine mammals and sea turtles that can be unintentionally killed or injured with sword-fishing nets on the West Coast. (The Obama-era rules were initially withdrawn by the National Oceanic and Atmospheric Administration, but were later finalized following a court order. The agency has said it plans to revise the limits.)
64. Loosened fishing restrictions intended to reduce bycatch of Atlantic Bluefin Tuna.
65. Rolled back a roughly 40-year-old interpretation of a policy aimed at protecting migratory birds, potentially running afoul of treaties with Canada and Mexico.
66. Overturned a ban on using parts of migratory birds in handicrafts made by Alaskan Natives.
In progress
67. Opened nine million acres of Western land to oil and gas drilling by weakening habitat protections for the sage grouse, an imperiled bird. An Idaho District Court injunction temporarily blocked the measure.
68. Proposed ending an Obama-era rule that barred using bait to lure and kill grizzly bears, among other sport hunting practices that many people consider extreme, on some public lands in Alaska.
Toxic substances and safety
Completed
69. Rejected a proposed ban on chlorpyrifos, a pesticide linked to developmental disabilities in children. (Several states have banned its use and the main manufacturer of the pesticide in 2020 stopped producing the product because of shrinking demand.)
70. Narrowed the scope of a 2016 law mandating safety assessments for potentially toxic chemicals like dry-cleaning solvents. The E.P.A. said it would focus on direct exposure and exclude indirect exposure such as from air or water contamination. In November, a court of appeals ruled the agency must widen its scope to consider full exposure risks.
71. Reversed an Obama-era rule that required braking system upgrades for “high hazard” trains hauling flammable liquids like oil and ethanol.
72. Removed copper filter cake, an electronics manufacturing byproduct comprised of heavy metals, from the “hazardous waste” list.
73. Ended an Occupational Safety and Health Administration program to reduce risks of workers developing the lung disease silicosis. In February released guidance to include silica in OSHA's National Emphasis Program, a worker safety program.
74. Rolled back most of the requirements of a 2017 rule aimed at improving safety at sites that use hazardous chemicals that was instituted after a chemical plant exploded in Texas.
In progress
75. Proposed changing safety rules to allow for rail transport of the highly flammable liquefied natural gas.
76. Announced a review of an Obama-era rule lowering coal dust limits in mines. The head of the Mine Safety and Health Administration said there were no immediate plans to change the dust limit but has extended a public comment period until 2022.
Water pollution
Completed
77. Scaled back pollution protections for certain tributaries and wetlands that were regulated under the Clean Water Act by the Obama administration.
78. Revoked a rule that prevented coal companies from dumping mining debris into local streams.
Congress
79. Withdrew a proposed rule aimed at reducing pollutants, including air pollution, at sewage treatment plants.
80. Withdrew a proposed rule requiring groundwater protections for certain uranium mines. Recently, the administration’s Nuclear Fuel Working Group proposed opening up 1,500 acres outside the Grand Canyon to nuclear production.
In progress
81. Attempted to weaken federal rules regulating the disposal and storage of coal ash waste from power plants, but a court determined the rules were already insufficient. Proposed a new rule to allow coal ash impoundments of a type previously deemed unsafe a pathway to proving safety.
82. Proposed a rule exempting certain types of power plants from parts of an E.P.A. rule limiting toxic discharge from power plants into public waterways.
83. Proposed weakening a portion of the Clean Water Act to make it easier for the E.P.A. to issue permits for federal projects over state objections if the projects don't meet local water quality standards, including for pipelines and other fossil fuel facilities.
84. Proposed extending the lifespan of unlined coal ash holding areas, which can spill their contents because they lack a protective underlay.
85. Proposed a regulation limiting the scope of an Obama-era rule under which companies had to prove that large deposits of recycled coal ash would not harm the environment.
86. Proposed a new rule allowing the federal government to issue permits for coal ash waste in Indian Country and some states without review if the disposal site is in compliance with federal regulations.
87. Proposed doubling the time allowed to remove lead pipes from water systems with high levels of lead.
Other
Completed
88. Repealed an Obama-era regulation that would have nearly doubled the number of light bulbs subject to energy-efficiency standards starting in January 2020. The E.P.A. also blocked the next phase of efficiency standards for general-purpose bulbs already subject to regulation.
89. Changed a 25-year-old policy to allow coastal replenishment projects to use sand from protected ecosystems.
90. Limited funding of environmental and community development projects through corporate settlements of federal lawsuits.
91. Stopped payments to the Green Climate Fund, a United Nations program to help poorer countries reduce carbon emissions.
92. Reversed restrictions on the sale of plastic water bottles in national parks designed to cut down on litter, despite a Park Service report that the effort worked.
In progress
93. Proposed a sweeping overhaul of the National Environmental Policy Act that would limit the scope of environmental concerns federal agencies need to take into account when constructing public infrastructure projects, such as roads, pipelines and telecommunications networks.
94. Proposed limiting the studies used by the E.P.A. for rulemaking to only those that make data publicly available. (Scientists widely criticized the proposal, saying it would effectively block the agency from considering landmark research that relies on confidential health data.)
95. Proposed changes to the way cost-benefit analyses are conducted under the Clean Air Act, Clean Water Act and other environmental statutes.
96. Proposed withdrawing efficiency standards for residential furnaces and commercial water heaters designed to reduce energy use.
97. Created a product category that would allow some dishwashers to be exempt from energy efficiency standards.
98. Initially withdrew, and then delayed, a proposed rule that would inform car owners about fuel-efficient replacement tires. (The Transportation Department has scheduled a new rulemaking notice for 2020.)
Some rules were rolled back, then reinstated
These rules were initially reversed by the Trump administration but were later reinstated, often following lawsuits and other challenges.
1. Stopped enforcing a 2015 rule that prohibited the use of hydrofluorocarbons, powerful greenhouse gases, in air-conditioners and refrigerators. A court later restored the prohibition.
2. Sought to repeal emissions standards for “glider” trucks — vehicles retrofitted with older, often dirtier engines — but reversed course after Andrew Wheeler took over as head of the E.P.A.
3. Sought to lift restrictions on mining in Bristol Bay, Alaska, but later suspended the effort. (A court ruled the E.P.A. could withdraw a 2014 determination that the project was a too great a threat to the Bay's salmon. The federal permit for the mine is pending with the U.S. Army Corps of Engineers.)
4. Delayed a compliance deadline for new national ozone pollution standards by one year, but later reversed course.
5. 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.
6. Initially delayed publishing efficiency standards for household appliances, but later published them after multiple states and environmental groups sued.
7. 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.)
8. 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.
9. Delayed federal building efficiency standards until Sept. 30, 2017, at which time the rules went into effect.
10. Ordered a review of water efficiency standards in bathroom fixtures, including toilets. E.P.A. determined existing standards were sufficient.
