PHMSas Closes Hazmat Case Against North Texas Air Supply Co.

The Pipeline and Hazardous Materials Safety Administration posted a compromise order on October 22, 2026, closing an enforcement matter against Quality Air Products Inc., doing business as Air Supply of North Texas, based in Richardson, Texas. The order, filed under PHMSA Case No. 25-0136-SH-CE, resolves a hazardous materials enforcement action brought under the federal hazardous materials transportation law, 49 U.S.C. § 5101 et seq., and the Hazardous Materials Regulations in 49 CFR Parts 171-180.

The posted document is the agency's standard compromise-order template plus a certificate of service showing PHMSA served the order on the company's president, Michael Wallis, on October 21, 2026. The template fields for the number of violations found and the total civil penalty due were left blank in the version posted to the docket, so the specific penalty amount is not yet confirmed from this filing. The order also lays out standard payment, interest and Treasury offset terms that apply once a penalty is finalized.

PHMSA regularly closes hazmat cases this way, agreeing to a negotiated penalty instead of litigating contested violations.
