HR-7849-119
Referred to the House Committee on Energy and Commerce.
Sponsored by Victoria Spartz (R-IN)
What it does
This bill would amend Section 213 of the Clean Air Act to fully exempt nonroad engines and vehicles used for agricultural purposes from federal emission standards. Currently, the EPA sets emission standards for nonroad engines — including tractors, combines, and other farm equipment — under that section. If enacted, those standards would no longer apply to any engine or vehicle used for agricultural purposes.
Who benefits
Farmers and agricultural operations of all sizes who currently must purchase or retrofit equipment to meet EPA nonroad emission standards. Farm equipment manufacturers who would face fewer regulatory compliance costs and could sell older or less expensive engine designs. Rural agricultural communities where farming is the primary economic activity. Used farm equipment dealers who sell older, non-compliant machinery. Developing-country equipment exporters who may gain market access if U.S. standards no longer apply to agricultural equipment sold domestically.
Who is hurt
Rural and agricultural communities located near farm operations who would be exposed to higher levels of diesel particulate matter, nitrogen oxides, and other pollutants from unregulated equipment. Children and elderly residents in farming regions, who are more vulnerable to air quality impacts. State and local air quality agencies that rely on federal nonroad emission standards to meet their own Clean Air Act attainment obligations. Equipment manufacturers who have already invested in compliant engine technology and would face competition from lower-cost, non-compliant alternatives. Public health systems that may bear costs associated with increased respiratory illness in affected areas.
Supporters argue
Supporters argue that farm equipment operates in open, rural environments where emissions disperse quickly and pose far less concentrated risk than on-road vehicles in urban areas, making blanket federal standards disproportionate to the actual public health impact. They contend that EPA nonroad emission rules impose significant upfront costs on farmers — compliant diesel engines can cost tens of thousands of dollars more than older designs — squeezing margins in an industry already under severe economic pressure from input costs and commodity price volatility. They further argue that farmers, as stewards of the land, have strong self-interest in maintaining healthy local environments and that state-level regulation is better suited to address localized agricultural air quality concerns.
Opponents argue
Opponents argue that nonroad agricultural equipment is a significant source of nitrogen oxide and particulate matter emissions — EPA data show nonroad diesel engines contribute roughly 20% of mobile-source NOx nationally — and that exempting this entire category would meaningfully worsen air quality in rural areas and undermine states' ability to meet federal air quality standards. They contend that the bill's title ("Farm Equipment Safety Act") does not reflect its actual mechanism, which removes pollution controls rather than adding safety measures, and that the health burden of increased emissions would fall disproportionately on the same rural communities the bill aims to help. They further argue that existing EPA programs already provide compliance flexibility and cost assistance for small agricultural operations, making a blanket exemption broader than necessary.
Constitutional context
The Clean Air Act's nonroad engine standards rest on Congress's Commerce Clause authority (Art. I, §8, cl. 3), which is well-established for regulating equipment that moves in interstate commerce or affects interstate markets. This bill does not expand agency authority — it restricts it by statute — so the major questions doctrine (West Virginia v. EPA, 2022) and post-Loper Bright heightened scrutiny are not directly implicated; Congress is acting within its own clear legislative power rather than delegating ambiguous authority to an agency.
Checks and balances
Congress would reduce EPA's regulatory authority over agricultural nonroad engines; states retain some authority to set their own standards under the Clean Air Act's savings clause, though California's waiver process and other states' ability to adopt California standards would be the primary remaining check on agricultural equipment emissions.
Historical precedent
Congress has previously created targeted exemptions from Clean Air Act requirements for specific categories, such as small spark-ignition engines and certain recreational vehicles, though a blanket exemption for all agricultural nonroad equipment of this scope has not previously been enacted.
