EPA Approves Carboxin Pesticide Limits on Crops
Published Date: 8/21/2026
Rule
Summary
This regulation establishes tolerances for residues of carboxin in or on multiple crops that are discussed later in this document. Under the Federal Food, Drug, and Cosmetic Act (FFDCA), UPL Delaware Inc. submitted a petition to EPA requesting that EPA establish a maximum permissible level for residues of this pesticide in or on the identified commodities.
Analyzed Economic Effects
5 provisions identified: 2 benefits, 3 costs, 0 mixed.
Infants Use 87% of Safety Limit
EPA's chronic exposure estimate shows that all infants under 1 year old use 87% of the chronic population-adjusted dose (cPAD) for carboxin under the assessed food and drinking water scenarios. EPA concluded that chronic exposures at this level are "not of concern" and determined the tolerances are safe.
FQPA Safety Factor Set to 1X
For dietary exposure scenarios, EPA set the Food Quality Protection Act (FQPA) safety factor for infants and children to 1X. EPA states this applies to current uses and would also apply to any future non-occupational/residential uses except inhalation scenarios.
New Carboxin Residue Limits
If you are an agricultural producer, food manufacturer, or pesticide maker, EPA established legal residue limits for carboxin on three crop subgroups effective August 21, 2026: Vegetable, legume, forage and hay, except soybean, subgroup 7-22A at 2 parts per million (ppm); Vegetable, legume, pulse, bean, dried shelled, except soybean, subgroup 6-22E at 0.2 ppm; and Vegetable, legume, pulse, pea, dried shelled, subgroup 6-22F at 0.2 ppm. These are the maximum permissible residue levels you must meet when selling or processing those commodities.
Removal of Bean, Dry Seed Tolerance
EPA removed the existing tolerance for "Bean, dry, seed" at 0.2 ppm because that commodity is now covered by the new tolerance for Vegetable, legume, pulse, bean, dried shelled, except soybean, subgroup 6-22E at 0.2 ppm. This change is effective August 21, 2026 and consolidates the tolerance entries.
Analytical Methods and LOQ Limits
EPA states that enforcement methods exist for measuring carboxin and metabolites, including colorimetric, gas-liquid chromatography (GLC), and GLC/mass selective detector methods. The residue data method limit of quantitation (LOQ) was 0.025 ppm while the enforcement analytical methods LOQ was 0.2 ppm, which EPA notes affects several tolerances set at 0.2 ppm.

2026-13667, Minor New Source Review Program Air Permitting Public Participation Requirements for State Implementation Plans
The EPA wants to give states more freedom to decide how much public input is needed when approving small air pollution sources or changes. This means local air agencies can tailor public participation to fit their community’s needs while still protecting air quality. If you’re involved in air permits, watch for comment deadlines and possible virtual hearings this summer!
2026-13263, Revisions To Establish the Sixth Unregulated Contaminant Monitoring Rule (UCMR 6) for Public Water Systems
The EPA is rolling out the sixth Unregulated Contaminant Monitoring Rule (UCMR 6) to check for new, sneaky chemicals in public drinking water. Big water systems serving 3,300+ people and some smaller ones will test for 30 different contaminants, including certain PFAS and pesticides, to keep our water safe. Comments and feedback are open until late August 2026, and the EPA will host fun online meetings to chat about the plan!

The EPA is giving U.S. Ecology Nevada a special green light to handle and dispose of high-mercury waste a bit differently than usual. This means mercury waste treated in Pennsylvania can now be safely sent to U.S. Ecology’s Nevada site for disposal under new rules starting July 27, 2026. This change helps protect people and the environment while keeping mercury waste management efficient and cost-effective.

The EPA is updating rules to phase down hydrofluorocarbons (HFCs), chemicals used in cooling systems like refrigerators and air conditioners. These changes affect businesses in refrigeration, supermarkets, semiconductor manufacturing, and more, allowing some older equipment made before 2025 to keep running. The new rules kick in on July 27, 2026, helping industries transition smoothly while cutting harmful emissions.
