Recent Projects

In February 2024, EPA finalized amendments to its Risk Management Program (RMP), under Section 112(r) of the Clean Air Act, to better protect vulnerable communities from chemical disasters that release toxic air pollution. In line with Policy Integrity’s recommendations, the final rule has been strengthened relative to the proposal and includes considerably more attention to the issues of underreporting, unquantified benefits, and the risks of catastrophic incidents. EPA has further improved the final rule to include consideration of climate change-related hazards in line with Policy Integrity’s recommendation to cover climate change-exacerbated hazards in addition to climate change-caused hazards. This will be increasingly important as the risks and magnitude of future chemical incident damages will likely only grow as climate change exacerbates severe weather that can spur power outages and chemical disasters.

On February 23rd, Policy Integrity submitted comments to EPA on its draft Scientific Integrity Policy. The draft Policy appropriately clarifies that economic analyses are protected by the same integrity policies as other scientific assessments, but it currently cites EPA's 2010 Guidelines for Performing Economic Analyses as the only example of a best-practice document that "should be followed" when assessing benefits, costs, and economic impacts. Several key elements of those 2010 guidelines are out of date, notably the recommendations on discount rates. Our comments offer a simple redline to ensure that other documents that meet the standards for objectivity--like the updated Circular A-4, or the pending ecosystem service guidance--could also fall under the Policy's proposed protections. 

EPA seeks comments on the it's Draft Revised EJ Technical Guidance, which highlights technical approaches that analysts can use to evaluate environmental justice concerns in regulatory actions. The Institute for Policy Integrity's comments to the agency advocate for enhanced documentation and transparency in environmental justice assessments.

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.

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.

In May 2023, 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. This proposal included revisions to strengthen the limits for new gas fired-plants and to establish limits for existing coal-fired plants and some of the largest, existing gas-fired plants. To determine the stringency of these limits, EPA identified “best systems of emission reduction” (BSERs). In our comments we explain how EPA’s has selected BSERs that are traditional in scope and consistent with the legal pathway left intact by the Supreme Court’s decision in West Virginia v. EPA. We also recommend that EPA strengthen the design of the rule to ensure it best fulfills its goal to reduce GHG emissions, which endanger public health and welfare, in a manner that avoids creating perverse incentives.

In May 2023, EPA proposed to strengthen tailpipe emissions standards for greenhouse gas and criteria pollutants for both light-duty and medium-duty vehicles. The standards apply to vehicle model years beginning in 2027 and would increase in stringency through model year 2032. In our comment letter, we explain that the Proposed Rule represents a sensible approach to cost-effectively reducing motor vehicle pollution that contributes to climate change and harms public health. We suggest that EPA take some additional steps to robustly support the regulation and ensure a complete presentation of benefits and costs.
