A recent incident at a refinery owned by Marathon Petroleum released over 15 tons of pollutants into the air. The release occurred between August 4 and 7 and caused intense odors that forced some people to leave their homes. The pollutants included hydrocarbons and carcinogenic chemicals.

The incident has raised questions and concerns about what went wrong and how the company and environmental regulators have responded.

Further details about the incident and the response to it are available from the El Paso Matters Podcast, which discussed the issue in a recent episode recorded on August 13, 2026. A transcript of the episode is also available.
