Produced Water Management: Texas's New Pit Rules 2026
If you operate a well site in Texas, the rules governing how you handle and manage produced water changed in a significant way this month. On July 1, 2026, the Railroad Commission of Texas’s (RRC) overhauled Chapter 4 waste regulations hit their first hard compliance deadline. Basic sediment pits and flare pits are no longer authorized. Produced water recycling pits that manage your well’s byproduct water now carry new financial security obligations. And the RRC’s new online registration portal launched on July 13, 2026. Here’s what changed, and why this is also a good moment to check the containment on the equipment surrounding your produced water site.

What Changed in the RRC's Waste Pit Rules?
On December 17, 2024, the RRC adopted comprehensive new regulations governing the handling, storage, treatment, and disposal of oil and gas waste, the first meaningful update to these rules since the 1980s. Published in the Texas Register on January 3, 2025, the rules took effect July 1, 2025, and introduced, for the first time, a registration requirement for the earthen pits used throughout drilling and production operations. For a detailed legal breakdown, Troutman Pepper Locke’s analysis of the new RRC rules covers the compliance framework in depth.
Which Pits Are No Longer Authorized?
The rules sort pits into categories, and not every pit qualifies for registration. Basic sediment pits and flare pits are no longer authorized under Chapter 4; operators using them must close the pit or replace it with a permitted system. Schedule A pits (reserve, mud circulation, completion/workover, makeup water, and others) had a one-year grace period after the July 2025 effective date, but existing qualifying pits must now be registered or closed by July 1, 2026, a deadline that just passed.
New Requirements for Produced Water Recycling Pits
If you operate a produced water recycling pit, a system designed to handle, treat, or recycle the water produced during drilling and production, your compliance checklist has expanded:
- Financial security required: performance bonds, letters of credit, or cash deposits, to secure closure obligations
- Engineered liner required only if: groundwater is within 50 feet of the pit, groundwater contains more than 3,000 mg/L of total dissolved solids, or the pit treats produced water
- Soil sampling and release reporting required at closure
While you’re reviewing the site for this registration, it’s also worth walking the transfer pumps, hose connections, and tank batteries nearby to confirm they’re properly contained. Systems like SiteGuard and MobileGuard are built for that kind of equipment.
The July 2026 Registration Deadline and Portal
As of July 13, 2026, the RRC’s new LoneSTAR portal is live for registering Schedule A-authorized pits, according to the RRC’s official notice published on July 9, 2026. The system does not require RRC approval; a pit is registered once the information is complete and correct. Operators without existing LoneSTAR access must first set up an RRC Access Management Process account.
What If Your Produced Water System Isn't Registered?
If your site still relies on an unregistered earthen pit or a basic sediment pit for produced water management, you are now out of compliance. Waiting on this only narrows your options as the RRC gains visibility into which sites have registered and which haven’t.
Next Steps
- Check your pit category against the RRC’s Schedule A list to confirm whether it needs registration.
- If yes, log into LoneSTAR or file Form EP-1 before September 1, 2026.
- While you’re on site, check that the transfer pumps, hose connections, and tank batteries near your produced water pit are properly contained, and contact AssetGuard if anything needs attention.
Questions About Produced Water Management Compliance
Does my produced water pit require an engineered liner?
Only if groundwater is within 50 feet of the pit, groundwater contains more than 3,000 mg/L of total dissolved solids, or the pit treats produced water. Lining a full pit is possible but isn’t the most common or cost-effective option for most sites.
What is the deadline for registering my produced water pit?
July 1, 2026, was the hard deadline. Email filings through September 1, 2026, are accepted but may face delays. Unregistered pits are out of compliance.
Do I need a performance bond for my produced water recycling pit?
Yes. All produced water recycling pits must carry financial security (performance bonds, letters of credit, or cash deposits) to secure closure obligations.
What else should I check while registering my produced water site?
The transfer pumps, hose and pipe connections, and tank batteries around your produced water pit are worth a look during this process too.
Who enforces these rules?
The Railroad Commission of Texas (RRC) adopted and enforces these rules under its Chapter 4 waste management regulations, which took effect July 1, 2025.
AssetGuard has engineered secondary containment for oil and gas operations for over 20 years. If your registration review turns up gaps anywhere on site, reach out to AssetGuard to talk through the right containment solution.
