MATS

Former EPA employees at the Environmental Protection Network (EPN) strongly oppose the Environmental Protection Agency’s (EPA) proposal to repeal all federal limits on greenhouse gas (GHG) emissions from fossil fuel-fired power plants and to rescind the most recent update to the Mercury and Air Toxics Standards (MATS). These proposals represent a sweeping dismantling of critical […]

In an unprecedented move, the U.S. Environmental Protection Agency (EPA) on April 25 simultaneously finalized four major environmental rules covering greenhouse gases (GHG), air toxics, wastewater discharges, and coal combustion residuals from fossil fuel-fired power plants. Among the rules is the EPA’s final Carbon Pollution Standards, which marks the agency’s third attempt to broadly curb […]

A proposed rule unveiled by the Environmental Protection Agency (EPA) on April 5 could considerably tighten the Mercury and Air Toxics Standards (MATS) for power plants, with specific repercussions for coal- and oil-fired generation. The proposed rule seeks to significantly update the 2012–finalized National Emission Standards for Hazardous Air Pollutants (NESHAP) for Coal- and Oil-Fired […]

The Environmental Protection Agency (EPA) is readying a regulatory sweep targeting more stringent limits on traditional pollutants that could accelerate coal power plant closures. A coal trade group estimates that even without new rules, 86 GW of coal generation is slated to retire by 2030. While the U.S. Supreme Court in June curtailed the EPA’s […]

Over its 50-year history, several rules issued by the U.S. Environmental Protection Agency (EPA) have reshaped the power sector. But for at least a few modern rules, the road has been full of turns. Notes: CAA = Clean Air Act; BSER = best system of emission reduction; CO2 = carbon dioxide; GHG = greenhouse gases; […]

The Environmental Protection Agency (EPA) on April 16 withdrew the legal justification for an Obama-era rule that required coal-fired power plants to reduce their emissions of mercury. The Mercury and Air Toxic Standards (MATS) remains in place, but Thursday’s action by the Trump administration could prevent similar regulations from being implemented in the future. EPA […]

The U.S. Environmental Protection Agency (EPA) will act on a spate of power plant rules over the next year, its newly released agenda of regulatory and deregulatory actions shows. The May 23-released “Spring 2019 Agenda of Regulatory and Deregulatory Actions” lists 35 new actions, along with 57 actions that it considers “deregulatory.” The list includes new […]

A bipartisan group of U.S. senators are urging the Environmental Protection Agency (EPA) to withdraw a proposed rule that they said could “lead to the undoing” of the Obama administration’s Mercury and Air Toxics Standards (MATS).  In a March 18 letter to newly appointed EPA administrator Andrew Wheeler, the group led by Sens. Lamar Alexander […]

The Senate on February 28 officially confirmed Andrew Wheeler to be administrator at the Environmental Protection Agency (EPA) on a 52–47 vote, mostly along party lines. The nomination of Wheeler, a former coal lobbyist, was controversial, with many lawmakers and environmentalists criticizing his ties to the coal industry.  Wheeler has held the role in an acting […]

While the Republican-led U.S. House and Senate in the 115th Congress was mainly focused on reviewing, for modification or repeal, several environmental rules issued under the Clean Air Act (CAA), the new Democrat majority in the House could focus on a slew of different measures, a new report from the Congressional Research Service (CRS) suggests.  […]
