EPA Greenlights Tree Sap Goo in Your Pesticides
Published Date: 6/18/2026
Rule
Summary
The EPA just made it official: resin acids mixed with glycerol can be used in pesticides on crops without worrying about residue limits. This means farmers, food makers, and pesticide companies get a smoother ride—no more setting max residue levels for this ingredient. The rule kicks in June 18, 2026, and if anyone wants to object, they have until August 17, 2026 to speak up.
Analyzed Economic Effects
3 provisions identified: 2 benefits, 0 costs, 1 mixed.
Tolerance Exemption for Surfactant Use
Effective June 18, 2026, EPA exempts residues of resin acids, esters with glycerol (CAS No. 8050-31-5) from the requirement of a tolerance when used as an inert surfactant on growing crops and raw agricultural commodities pre- and post-harvest. EPA says no numerical residue limit or analytical enforcement method is required for food commodities when the ingredient is used under this exemption, removing the need to establish a maximum permissible residue level.
50% Cap Enforced in Registrations
EPA will not register any pesticide formulation for food use that exceeds 50% resin acids, esters with glycerol in the finished pesticide formulation. The 50% maximum concentration will be enforced through the pesticide registration process, so manufacturers must keep this ingredient at or below 50% for food-use products.
EPA Finds No Safety Concern
EPA concluded there is a reasonable certainty that no harm will result to the general population, including infants and children, from aggregate exposure to residues of resin acids, esters with glycerol when used as allowed by this rule. You can expect EPA determined available toxicity data show low toxicity and therefore did not identify toxicological endpoints of concern for this use.

2026-19072, Rescission of the Greenhouse Gas Findings for Fossil Fuel-Fired Power Plants and Repeal of Regulations for Power Plant Greenhouse Gas Emissions Under Clean Air Act Section 111
The EPA is proposing to cancel all greenhouse gas rules for fossil fuel power plants, saying the law doesn’t let them regulate these emissions for climate reasons. This change affects power plants across the U.S. and could impact future pollution limits and costs. Comments on this proposal are open until November 2, 2026, so now’s the time to speak up!
2026-19071, Partial Repeal of the Carbon Pollution Standards for Fossil Fuel-Fired Electric Generating Units
The EPA is rolling back most of the 2024 rules that limited carbon pollution from fossil fuel power plants. This change affects coal and gas plants by easing some strict limits on emissions and carbon capture technology. The new rules kick in on November 16, 2026, potentially saving money for power plants but raising questions about pollution control.
2026-18317, Updated Definition of “Waters of the United States”
The purpose of this supplemental notice of proposed rulemaking is for the U.S. Environmental Protection Agency (EPA) and the Department of the Army ("the agencies") to supplement and seek additional comment on certain aspects of an earlier proposal, published on November 20, 2025, to revise the regulations defining the scope of waters federally covered under the Clean Water Act in light of the U.S. Supreme Court's 2023 decision in Sackett v. Environmental Protection Agency. As stated in the agencies' November 20, 2025 Notice of Proposed Rulemaking (NPRM), the agencies intend for this rulemaking to provide greater regulatory certainty and increase Clean Water Act program predictability and consistency by clarifying the definition of "waters of the United States." After consideration of the public comments received on the NPRM, the agencies are issuing this notice to supplement the NPRM with additional regulatory options on certain aspects of the proposed rule.
2026-14112, Amendments and Nonconformance Penalties for Model Year 2027 and Later Heavy-Duty Highway Engines and Amendments to Inducement Provisions for SCR-Equipped Diesel Engines
Starting with model year 2027, the EPA is updating rules for big truck engines to make sure they last longer and pollute less. They’re also letting engine makers pay penalties if their engines don’t meet standards, and tightening rules for special pollution-control systems on diesel engines. These changes affect truck and engine makers and kick in soon, with public feedback due by August 29, 2026.
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!

On June 27, 2026, the Coast Guard will set up a temporary safety zone on the Allegheny, Ohio, and Monongahela Rivers near Pittsburgh from 9:30 to 10:30 p.m. This zone keeps boats and people out during a cool drone show to keep everyone safe from falling debris and low-flying drones. If you’re on the water, you’ll need special permission to enter, but no fees or long delays are expected.
