EPA revised the National Ambient Air Quality Standards (NAAQS) for Particulate Matter (PM) in March. The state of Kentucky and others filed a lawsuit in the D.C. Circuit arguing that EPA should have considered costs when setting its 2024 NAAQS for PM. We filed an amicus brief explaining that EPA appropriately assessed costs in its separate regulatory impact analysis, that considering regulatory costs would not lead to a less stringent standard, and that there is no history of EPA considering costs when revising the NAAQS.

The State of Utah and others filed a lawsuit over EPA’s new Good Neighbor Rule in the U.S. Court of Appeals for the D.C. Circuit. The rule is the latest in a long line of EPA regulations effectuating the requirement that upwind States eliminate emissions that “significantly contribute” to downwind States’ inability to meet certain ambient air quality standards. We filed an amicus brief rebutting multiple arguments against the rule. Our brief explains that addressing the serious and complex spillover effects caused by air pollution was a central justification for the Clean Air Act and EPA’s regulatory impact analysis demonstrates that the rule is economically justified.  

In April 2024, EPA proposed retaining the secondary national ambient air quality standards (NAAQS) for nitrogen oxides (NOx) and particulate matter (PM) and setting a new annual average standard for sulfur oxides (SOx). Policy Integrity submitted comments arguing that although the Proposed Rule begins to assess the various adverse welfare effects of SOx, NOx, and PM emissions and depositions that different populations may face, EPA should assess, consider, and present more information regarding both distributional impacts and future risks. 

In January 2024, the Environmental Protection Agency (EPA) proposed a regulation under the Clean Water Act that would impose new effluent limitations guidelines and standards for the meat and poultry products point source category. As EPA documents, the proposed standards would help improve health and water quality near these slaughterhouse facilities. It would also carry benefits stemming from better-protected habitats for a variety of wild animals. In our comment letter, we explain that, while the Proposed Rule and its accompanying regulatory impact analysis reasonably explain many of these benefits, EPA should take further steps to ensure the complete presentation of regulatory benefits and costs, along with their distribution, and to present its decisionmaking factors transparently.

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 May, the Pipeline and Hazardous Materials Safety Administration released a draft regulation to prevent methane leaks from gas pipelines. The agency monetized the climate benefits of the regulation using the social cost of methane, finding that monetized benefits exceeded monetized costs by at least $340 million per year. In our comment letter, we support the agency for applying the social cost of greenhouse gases to estimate the climate benefits of the proposed rule. We also suggest that PHMSA apply additional analysis to each rule using draft updated climate-damage valuations that the Environmental Protection Agency released in November 2022.

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.

In March, the Environmental Protection Agency (EPA) proposed to strengthen its power plant effluent guidelines by tightening discharge requirements for flue gas desulfurization wastewater, bottom ash transport water, and combustion residual leachate resulting from steam electricity generation. In our comment letter, we offer several recommendations for EPA to strengthen its consideration of regulatory benefits. 

In March 2023, the Consumer Product Safety Commission (CPSC) published a Request for Information on Chronic Hazards Associated with Gas Ranges and Proposed Solutions. We submitted comments which highlighted the major findings from our report. We explained how the CPSC could regulate gas ranges and recommened possible futher actions.
