NOTICE TO OIL AND GAS OPERATORS

New Mechanical Integrity Test (MIT) Schedule Notification System

April 15, 2026

As part of the State Tracking and Reporting (LoneSTAR) project, a new Mechanical Integrity Test (Form H-5) notification system was developed to prevent delays in relaying the H-5 test schedule and to provide a comprehensive list of H-5 violations and delinquencies. The notification system will impact UIC wells permitted under Statewide Rules 9, 46, 81, 82, 95, 96, 97 and 16 TAC §5.202 (a)(2).

Effective June 1, 2026, the Railroad Commission of Texas (RRC) will no longer mail H-5 notifications to the address listed on your Organization Report (Form P-5). All H-5 notifications will be sent to the primary email address designated on your Form P-5, which will be shared in a Microsoft Excel spreadsheet. The Microsoft Excel spreadsheet will include the following tabs:

  • Well Test and Survey Schedule – A list of all UIC wells with an MIT due within the next six months.
  • Delinquency Notice – A list of all overdue H-5.
  • H-5 Violation Notice – A list of all outstanding inconclusive and failed violations generated from an H-5 test filing.

In addition to transitioning away from the paper-based H-5 notifications, the frequency of notification letters will change from quarterly to monthly. All H-5 notifications will be sent online on the first working business day of each month.

The H-5 notification system update does not affect the process for submitting an H-5 filing or the current H-15 system. All H-5 tests must be filed online using the RRC Online System. (https://webapps.rrc.texas.gov/security/login.do). The results of any submitted H-5 filing will continue to be emailed to the H-5 filer; however, the mailed paper letter for each failed MIT and inconclusive MIT will no longer be sent. Instead, it will be listed in the H-5 Violation Notice tab on the Excel spreadsheet.

Please note that a primary email must be defined on your Form P-5, but a LoneSTAR account is not required to receive the H-5 notification. If you do not have an email registered on Form P-5, you will not receive any of the aforementioned notices. If you need to update your organization’s primary email address, you can do so in one of the following two ways:

Commission staff will host a presentation at the 2026 RRC Regulatory Conference outlining the new H-5 notification system and any related updates. In addition, a cover letter explaining the new notification process will accompany the Excel spreadsheet.
