EPA OKs Tongue-Twisting Sugar-Stearate Frankenstein for Bug-Killing Sprays
Published Date: 8/28/2026
Rule
Summary
The EPA just said it’s okay to use alpha-d-glucopyranoside, beta-d-fructofuranosyl, mixed palmitates and stearates as a safe ingredient in pesticides on crops, without worrying about residue limits. This helps farmers and pesticide makers by cutting red tape and starts right away on August 28, 2026. If anyone has concerns, they have until October 27, 2026, to speak up.
Analyzed Economic Effects
4 provisions identified: 3 benefits, 1 costs, 0 mixed.
12% Pre‑Harvest Surfactant Exemption
The EPA exempted residues of alpha-d-glucopyranoside, beta-d-fructofuranosyl, mixed palmitates and stearates (CAS No. 84066-95-5) from the requirement of a tolerance when used as an inert surfactant on growing crops pre-harvest at no more than 12% of the final pesticide formulation. This exemption is effective August 28, 2026 and means EPA will not set a numeric maximum permissible residue level for these uses.
Registration Limit: No Formulations Over 12%
EPA will enforce the 12% concentration limit through the pesticide registration process under FIFRA and will not register any pesticide formulation for food use that exceeds 12% of this surfactant in the final formulation. This enforcement posture takes effect with the rule on August 28, 2026.
No Analytical Tolerance or Test Required
Because EPA is establishing an exemption rather than a numeric tolerance, the Agency says an analytical enforcement method is not required for residues of this ingredient in or on food commodities. Instead, compliance with the 12% limit will be checked through pesticide registration under FIFRA.
EPA Finds No Health Risk to Public
EPA reviewed toxicity data and concluded alpha-d-glucopyranoside, beta-d-fructofuranosyl, mixed palmitates and stearates have low toxicity, no toxicological endpoints of concern were identified, and there is a reasonable certainty of no harm to the general population or to infants and children from aggregate exposure. EPA therefore did not apply an extra tenfold safety factor for children and finalized the exemption effective August 28, 2026.

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.
2026-19072, 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!
2026-18317, 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!

If you own or fly Leonardo helicopters like the A109 or AW119, listen up! The FAA found a problem with a key part called the swashplate bearing that might be installed wrong. Starting October 2, 2026, you’ll need to check this part once and fix it if needed to keep flying safe—no sneaky installs allowed. This keeps your chopper safe without breaking the bank or your schedule.
