Recent Projects

In May 2023, the Environmental Protection Agency (EPA) proposed a package of regulations to limit greenhouse gas emissions from fossil fuel-fired power plants under Section 111 of the Clean Air Act. EPA subsequently issued a supplemental notice of proposed rulemaking, re-opening its comment period and soliciting comment on whether to include additional mechanisms to address potential reliability issues. In these comments, we explain why EPA has engaged in reasoned rulemaking and developed a robust administrative record comporting with its mandate to reduce power sector pollution. It remains the Federal Energy Regulatory Commission’s (FERC’s) responsibility to ensure reliable bulk-power system (BPS) operations and to use its corresponding tools to address the wider reliability challenges of the clean energy transition, in coordination with other reliability-related entities.

In October, EPA issued proposed restrictions on the manufacture, processing, and distribution of a chemical called trichloroethylene (TCE). We argue in comments that aspects of the agency’s Economic Analysis of the proposed restrictions could be clarified or expanded upon to better inform policymakers and the broader public about the benefits of ending TCE use.

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.
