米環境保護庁（EPA）は、トランプ政権下において、有害な石炭灰貯留池の監視権限を各州の規制当局へ移管する方針を固めた。この変更により、すでに5州が有している権限が拡大される一方、2015年に定められた連邦レベルの保護基準が弱まる可能性がある。専門家らは、州の予算削減が地下水汚染に対する地域住民の脆弱性を高める恐れがあると指摘している。
ジョージア州をはじめとする各州の河川沿いには、石炭灰が堆積した巨大なライナー（遮水シート）のない貯留池が点在しており、ヒ素や水銀といった重金属が地下水へ流出している。オバマ政権下の規則では監視と浄化が義務付けられていたが、抜け穴が多く、休止中の多くの拠点が規制対象外となっていた。今年4月、EPAは古い処分場を規制対象から除外することや、監視計画において各州により大きな裁量を与える案を提案した。

The Environmental Protection Agency has finalized a rule rescinding its 2009 finding that greenhouse gases from new motor vehicles endanger public health and welfare, a step the agency says eliminates its authority under the Clean Air Act to set greenhouse-gas standards for cars and trucks. The action—grounded in a new legal interpretation and the Supreme Court’s “major questions” doctrine—has drawn sharp criticism from Democrats and legal and scientific experts and is expected to face court challenges.
One year into Donald Trump's second term, the U.S. Environmental Protection Agency has undergone significant changes, including staff reductions and program cuts, prompting resistance from current and former employees. Workers like Montana Krukowski and Missy Haniewicz, who signed a public dissent letter, faced firings but are now appealing through legal channels. Advocacy groups are supporting efforts to preserve scientific integrity and rebuild the agency.

On February 12, 2026, the Trump administration repealed the Environmental Protection Agency's 2009 Endangerment Finding, which had established greenhouse gases as threats to public health and welfare. President Trump and EPA Administrator Lee Zeldin announced the move at the White House, describing it as the largest deregulatory action in U.S. history. The repeal undermines the legal foundation for numerous federal climate regulations.
Almost all liming of watercourses in Dalarna, aimed at protecting sensitive species, could end under a proposal from the Swedish Agency for Marine and Water Management. The County Administrative Board of Dalarna sharply criticizes the plan, warning that species could be wiped out permanently. The new assessment method would reduce the number of acidified watercourses from 43 percent to one percent.

Across the United States, Republican and Democratic lawmakers are aligning to regulate artificial intelligence and the energy-intensive data centers that power it, driven by concerns over electricity costs and resource use. President Trump has joined the push by urging tech companies to build their own power plants. This unusual cooperation contrasts with federal gridlock and reflects voter frustrations ahead of midterms.
