EPA Approves Missouri's Boring Emission Fee Updates
Published Date: 2/26/2026
Rule
Summary
The EPA just gave a thumbs-up to Missouri’s updated rules about reporting pollution data and paying emission fees from 2025 through 2028 and beyond. This update adds a new chemical to the hazardous list and tweaks some paperwork dates but won’t make the air dirtier or rules tougher. If you’re a Missouri business dealing with emissions, get ready for these changes starting March 30, 2026!
Analyzed Economic Effects
3 provisions identified: 0 benefits, 3 costs, 0 mixed.
Missouri per‑ton emission fees set
Missouri updated its emission fees and a base fee that apply per ton of air pollution for calendar years 2025-2028 and beyond. The revised emissions fee section (subsection (3)(A)) is effective January 1, 2026 and is approved into Missouri’s Title V Operating Permits Program (but that subsection is not approved into the SIP).
1‑Bromopropane added to HAP list
Missouri added 1‑Bromopropane to its category 1 Hazardous Air Pollutant list in table 1 as part of the revisions the EPA approved. This listing is part of the state rule revision that the EPA is incorporating by reference.
State rule incorporated and federally enforceable
EPA incorporated Missouri rule 10 CSR 10-6.110 by reference into the SIP so the materials are federally enforceable under sections 110 and 113 of the Clean Air Act as of the rule's effective date. The EPA states this approval does not impose requirements beyond State law.

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.

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.

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!

This change helps protect people and the environment while keeping mercury waste management efficient and cost-effective.
