EPA Approves Missouri's Boring Emission Fee Updates

## 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!

## Abstract

The Environmental Protection Agency (EPA) is taking final action to approve revisions to the Missouri State Implementation Plan (SIP) and the Missouri Operating Permits Program related to Reporting Emission Data, Emission Fees, and Process Information. The revisions set emission fees and a base fee for calendar years 2025-2028 and beyond, add 1-Bromopropane to the category 1 Hazardous Air Pollutant list in table 1, update two publication dates for material that is incorporated by reference and make minor administrative changes to the rule. These revisions do not impact the stringency of the SIP or have an adverse effect on air quality. The EPA's final approval of this rule revision is being done in accordance with the requirements of the Clean Air Act (CAA).

- 1‑Bromopropane added to HAP list: cost, low. 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: cost, low. 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.
