EPA’s long-promised rules for reducing CO2 emissions from fossil fuel-fired power plants have now been published. In the proposal, EPA lays out “performance standards” for new natural gas-fired power plants and “emission guidelines” for states to use in developing standards for existing gas- and coal-fired power plants.Continue Reading EPA’s New Carbon Standards for Power Plants Require Quick Decisions

In response to the transformational Inflation Reduction Act, Troutman Pepper has launched Taking Charge: Inside the U.S. Battery Boom, an in-depth report examining the accelerated growth in the U.S. battery storage sector.

EPA’s standards for hazardous air pollutant (HAP) emissions from industrial boilers have been controversial for nearly two decades. Ever since EPA first proposed “maximum achievable control technology” (MACT) standards for boilers in 2003, which were then entirely vacated by the D.C. Circuit, each new iteration of the rule has raised new legal issues and often foundered in court.

On the last day of what was already an historic term, the Supreme Court issued another significant decision impacting EPA’s authority under the Clean Air Act to regulate greenhouse gas emissions and address climate change. As EPA embarks on a third attempt at a rule targeting CO2 emissions from existing power plants that will pass legal muster, the question now is how the Court’s decision will affect that new rule.

In a proposed rule signed on February 28, but not yet published in the Federal Register, EPA proposed to significantly expand its current approach to regulating the interstate transport of ozone. Under the so-called “good neighbor” provision of the Clean Air Act, states are required to submit State Implementation Plans (SIPs) to EPA containing rules sufficient to prohibit emissions from their state that would either significantly contribute to another state’s nonattainment of national ambient air quality standards or interfere with another state’s maintenance of those standards. If a state submits a SIP that is insufficient to satisfy its good neighbor obligation, EPA must issue a Federal Implementation Plan (FIP) to fully address the problem.

On February 17, the Federal Energy Regulatory Commission (FERC or Commission) announced two new, significant policies that may have a profound impact on both natural gas pipeline projects before the Commission and the industry in general. Headlining these policies is FERC’s new interim greenhouse gas (GHG) policy statement (Interim GHG Policy Statement), pursuant to which FERC will presume any gas project with 100,000 metric tons per year of carbon dioxide equivalents (CO2e) emissions to have a significant impact on climate change and will trigger the preparation of an Environmental Impact Statement (EIS). Notwithstanding the interim nature of FERC’s new Interim GHG Policy Statement – where FERC is accepting comments by April 4, 2022 – FERC clarified that it will apply both policies to all pending and new project applications, effective immediately.

In a final rule published in the Federal Register on November 24, the Environmental Protection Agency (EPA) quietly finalized a hotly contested proposed rule, adding natural gas processing facilities to the list of industry sectors required to report their releases of certain chemicals under Section 313 of the Emergency Planning and Community Right-to-Know Act (EPCRA), also known as the Toxic Release Inventory (TRI). Facilities must report releases and waste management of specifically listed chemicals to the TRI if they: (1) have 10 or more full-time employees, (2) have a primary Standard Industrial Classification (SIC) or North American Industry Classification System (NAICS) code listed in the regulations, and (3) manufacture, process, or otherwise use certain listed chemicals in the course of a calendar year in quantities exceeding identified thresholds.

Earlier this week, EPA published its proposed new methane regulations for the oil and gas sector. These new rules will have significant practical implications for the industry and have the potential to set new precedent for EPA’s authority under the Clean Air Act to address climate change for other industries as well. While the proposal is over 150 pages long, it does not include the actual text of the proposed rules, promising instead to provide proposed text in a supplemental notice early next year.

The U.S. Supreme Court has elected to hear a legal dispute over the scope of the authority granted to the Environmental Protection Agency (EPA) under the Clean Air Act to regulate greenhouse gas (GHG) emissions from existing power plants. In orders issued October 29, the Court granted certiorari to four petitioners — West Virginia, North Dakota, the North American Coal Corporation, and Westmoreland Mining Holdings LLC — seeking reversal of a September 2020 D.C. Circuit Court of Appeals decision striking down the Affordable Clean Energy (ACE) rule.
