In August, the National Highway Traffic Safety Administration (NHTSA) proposed to strengthen vehicle fuel-economy standards. Since then, the Environmental Protection Agency has finalized its update to the social cost of greenhouse gases and the Office of Management and Budget has finalized its revisions to Circular A-4. In light of these updates, we submitted a supplemental comment letter reasserting our call for NHTSA to assess regulatory impacts using the best available economics.

Earlier this year, the Council of Environmental Quality (CEQ) published interim guidance on analyzing climate change effects under the National Environmental Policy Act in which it endorsed using the social cost of carbon in environmental analysis. In this supplemental comment letter, we suggest that CEQ specifically endorse the Environmental Protection Agency’s newly-updated climate-damage values when it finalizes the interim guidance.

On December 2nd, EPA released a new methane regulation that includes final updated values for the social cost of greenhouse gas metrics. The updated metrics align with many of the recommendations Policy Integrity made in our comments on the draft values, and our scholarship and analysis were cited heavily in the associated federal documentation.

In November 2020, EPA finalized a rule withdrawing the “Once-in, Always-in” Policy, under which facilities that are “major sources” of emissions at the first compliance date for the applicable standard must comply permanently with the requirements for a major source. This 2020 Rule allows major sources of toxic air pollution to reclassify as area sources, which are subject to less stringent or no emission control requirements. The 2020 Rule therefore creates the potential for very large increases in toxic air pollution. In September 2023, EPA proposed new safeguards to prevent increased emissions from sources that reclassify and restores federal enforceability requirements for potential to emit limits. We submitted comments on the analysis underlying the proposed new safeguards.

On November 9th, the White House finalized its revision of Circular A-4, the primary guidance on how federal agencies should assess the costs and benefits of regulations. This document plays a critical role in federal policymaking, and it had not been updated in two decades. The new guidance represents a major improvement over current practice and incorporates numerous changes that Policy Integrity has long recommended.

In September 2023, the Pipeline and Hazardous Materials Safety Administration (PHMSA) proposed a regulation to improve the safety of certain gas pipelines. The standards include a suite of reforms to help prevent incidents like the catastrophic 2018 gas pipeline explosions in Merrimack Valley, Massachusetts. In a comment letter, we explain that, while the Proposed Rule and its accompanying regulatory impact analysis are well grounded in applicable statutes and guidance, PHMSA should take further steps to bolster its analysis.

The 2017 Tax Act directed Bureau of Land Management (BLM) to conduct two sales in the Arctic National Wildlife Refuge (ANWR) area known as Coastal Plain totaling at least 400,000 acres by 2024. BLM released a final environmental impact statement (EIS) in September 2019 considering the over 1.5 million-acre area in the ANWR and held the first lease sale in January 2021. Later in 2021, the agency placed a moratorium on all activities relating to BLM’s Coastal Plain leasing program, announced that the analysis conducted in 2019 was legally deficient, and began to prepare a supplemental environmental impact statement. We filed comments on this new EIS and arged that the presentation of climate costs and benefits in the analysis could be made more complete and balanced.
