On December 30, 2025, EPA Region 6 issued an Administrative Order (AO) under its authority pursuant to Section 309 of the Clean Water Act to the City of Stephenville Wastewater Treatment Facility, in Stephenville, TX. The AO was issued in response to effluent violations of the Unit's TPDES permit limits. The AOs requires the facility to 1) immediately comply with the permit, 2) submit a list of specific actions taken to correct the violations with a certification that the violations have been corrected, or 3) submit a compliance plan if the violations cannot be corrected within 30 days. The Respondent must also reply to EPA within 30 days of the effective dated of the AO. The AO was issued because of a TCEQ referral for enforcement to EPA to expedite addressing the Significant Non-Compliance status under the Texas TPDES delegated program.
