EPA Unveils New Long Island Sound Plan, Proposes MATS Rollback for Power Plants

Big news from the Environmental Protection Agency this week: The EPA, alongside officials from New York, Connecticut, and other partners, marked the 40th anniversary of the Long Island Sound Partnership—formerly known as the Long Island Sound Study—unveiling an ambitious new 10-year roadmap to revitalize one of the Northeast’s most critical ecological and recreational resources. Administrator Lee Zeldin spoke at the ceremony, emphasizing the agency’s “unwavering commitment to restoring the Sound for future generations” and highlighting strengthened goals for water quality, habitat restoration, and community resilience.

In other major headlines, the EPA has announced a proposal to repeal the Biden-Harris era Mercury and Air Toxics Standards, or MATS Amendments, which were designed to limit toxic air emissions from power plants. This move aims to roll back regulations the agency says have imposed significant costs on the power sector, with the EPA estimating a regulatory savings of $1.2 billion over the next decade. Administrator Zeldin stated that this marks “the greatest day of deregulation in the history of the United States,” asserting that the agency remains dedicated to its mission of protecting health and the environment, while fulfilling the current administration’s promise to reduce energy costs and empower states to make more decisions locally.

For American citizens, these actions signal both new optimism for local environmental recovery—like cleaner waters and more recreational opportunities in Long Island Sound—and potential shifts in air quality protections, particularly near coal- and oil-fired power plants. For businesses, particularly in the energy sector, the promised regulatory relief could mean reduced compliance costs and more flexibility, while environmental groups have voiced concerns about the long-term impacts on public health and climate efforts.

State and local governments are taking center stage in these initiatives. The new Long Island Sound plan was developed in close collaboration with state leaders, who hailed the partnership as a model for regional cooperation. Meanwhile, the EPA’s deregulatory moves on power plant emissions are shifting more responsibility and authority to state agencies, especially on enforcement and permitting.

Internationally, the changes in emissions regulation may draw scrutiny from global partners, especially as climate action remains a key diplomatic issue. However, administration officials have argued that their approach strengthens energy independence and economic competitiveness.

Looking ahead, the EPA recently opened a public comment period on its proposed changes to power plant regulations, giving citizens and stakeholders a direct chance to weigh in. Deadlines for input will be posted on the EPA’s official website. The agency also announced extended deadlines for greenhouse gas reporting and several other rulemaking initiatives, reflecting its evolving priorities and ongoing response to court decisions such as the Supreme Court’s recent ruling on Clean Air Act judicial review.
