EPA Partially Agrees on Objections to TPC Group Permit

## Summary

The EPA reviewed complaints about the air pollution permit for TPC Group’s Houston plant and decided to agree with some concerns but not all. This means some changes to the permit might happen, affecting the company and local community air quality. Anyone unhappy with the decision has until August 21, 2026, to ask a court to review it.

## Abstract

The Environmental Protection Agency (EPA) Administrator signed an Order dated May 6, 2026, granting in part and denying in part a petition dated February 17, 2025, from Air Alliance Houston and petition dated February 17, 2025, from Harris County Attorney's Office (the Petitioners). The petitions requested that the EPA object to a Clean Air Act (CAA) title V operating permit issued by the Texas Commission on Environmental Quality (TCEQ) to TPC Group, LLC, for its Houston Plant located in Harris County, Texas.
