On March 31, 2020, the U.S. Environmental Protection Agency (“EPA”) and the National Highway Traffic Safety Administration (“NHTSA” and, collectively, the “Agencies”) released the pre-publication version of the final part to their joint Safer Affordable Fuel-Efficient (“SAFE”) Vehicles Rule. The new rule amends EPA’s greenhouse gas emission standards for passenger vehicles, light-duty trucks, and medium-duty passenger vehicles in model years 2021 and onward, and it simultaneously amends or creates NHTSA’s corporate average fuel economy standards for similar vehicles in model years (MY) 2021-2026. Under these harmonized regulations, each new model year will bring a 1.5% increase in stringency through MY 2026. Though a significant lessening of requirements from joint standards last set in 2012, this “steady ramp rate” is a notable change from the proposed version of the SAFE Vehicles Rule, which sought to maintain requirements as they applied in MY 2020. The new rule will take effect sixty days from its publication in the Federal Register.

Last week, EPA fulfilled a promise to reverse the expansion of its refrigerant management program during the Obama Administration. That expansion, which was finalized in 2016 and became effective in 2019, EPA extended the regulations for ozone depleting substances (ODS) to non-ODS “substitute” refrigerants, with the intent of reducing emissions of substitutes that consist of greenhouse gases (GHGs), including some with very high global warming potentials. Last week’s final rule returns the refrigerant management program to its original focus, at least with respect to appliance leak repair requirements, although some regulatory requirements for non-ODS substitute refrigerants will remain in place.

On June 21, 2019, the White House Council on Environmental Quality (CEQ) released a new draft guidance redefining the process federal agencies will use to evaluate greenhouse gas (GHG) emissions under the National Environmental Policy Act (NEPA). In marked contrast to GHG guidance issued by CEQ under the Obama Administration in 2016, the draft guidance encourages federal agencies undertaking NEPA review to follow the “rule of reason” and use their “expertise and experience” to decide whether and to what degree the agency will analyze particular effects of GHG emissions. Therefore, the draft guidance moves to a more deferential approach to agency review under NEPA than the Obama Administration’s prescriptive guidance. The draft guidance will be published in the Federal Register for public review and comment. If finalized, it will replace the Obama Administration’s 2016 guidance, which was withdrawn effective April 5, 2017, after President Trump issued Executive Order (EO) 13783, “Promoting Energy Independence and Economic Growth.” …

On June 13, 2019, EPA published a final rule that revises its release notification requirements under the Emergency Planning and Community Right-to-Know Act (EPCRA).  Specifically, the revision exempts from EPCRA reporting air emissions from animal waste at farms.  While these air emissions are now exempt from reporting requirements, releases from animal waste to other water and land must still be reported.…

EPA has reset the public hearing date on its proposed revisions to the New Source Performance Standards governing CO2 emissions from new, modified and reconstructed Electric Generating Units (EGUs).  The hearing, originally scheduled for January 8th and then postponed until January 30th, is now scheduled for February 14th in Washington, D.C.  Under the Clean Air…

In the last month of 2018, EPA released two proposals that it claims will have no immediate effect—revised CO2 standards for new coal-fired power plants that EPA does not expect anyone to build, and a determination that it is not “appropriate and necessary” to have a mercury rule that it nevertheless plans to keep on the books.  The question many may be asking is why EPA would issue two highly controversial rules if they won’t have any practical effect?  The answer may lie in the precedent they will set.

This afternoon, EPA announced proposed revisions to performance standards governing CO2 emissions from new, reconstructed and modified coal-fired electric generating units. The proposal would drop carbon capture and storage (CCS) as the best system of emission reduction (BSER) for new units in favor of efficient supercritical steam design for large units and subcritical design…

The comment period has now begun on EPA’s proposal for replacing the Clean Power Plan, named the “Affordable Clean Energy”—or “ACE”—rule.  The rule was published in the Federal Register on August 31. And there is plenty to keep commenters busy over the next 60 days, given that EPA expressly identified 75 distinct requests for comment,…

This morning, the Environmental Protection Agency (EPA) released its proposed replacement for the Clean Power Plan (CPP) titled the “Affordable Clean Energy Rule,” which would regulate greenhouse gas emissions at existing coal-fired power plants.   The proposed rule gives discretion to states for determining the greenhouse gas performance standards achievable for existing coal-fired power plants within their state.  Specifically, the proposed rule would require states to evaluate a menu of heat rate improvement options and, taking into account the unit’s remaining useful life and other factors, determine the lb/MWh CO2 emission rate achievable at each affected unit. While the rule proposes to allow for emissions averaging among affected units at an individual source, it does not provide for broader averaging or emissions trading.  To facilitate the heat rate improvement projects, EPA also has proposed an option for states to adopt a new emissions test under the New Source Review program for EGUs that is based on both hourly and annual emissions.

On July 25, California Governor Jerry Brown signed into law Assembly Bill 398, an extension of California’s greenhouse gas (GHG) cap-and-trade program through 2030.  Eight days after being introduced, AB 398 passed the California Legislature with a two-thirds majority vote of 55-22 in the Assembly and 28-12 in the Senate.  AB 398 implements California’s goal of reducing GHG emissions to 40 percent below 1990 levels by 2030, which was codified in SB 32, a bill signed by Governor Brown last year.
