For a Texas oil and gas operator, environmental compliance is not one regulator, it is a stack of them. The EPA sets the federal floor, the Railroad Commission of Texas (RRC) runs much of the day-to-day enforcement, and OSHA governs the worker-safety side of the same materials. The most expensive mistakes happen not inside any one agency's rules but in the seams between them. This primer lays out what the EPA regulates, what the RRC handles, and where the overlap creates risk.
What does the EPA regulate for oil and gas?
The Environmental Protection Agency protects the environment through federal statute, and for operators that authority translates into three programs that set the compliance baseline nationwide, including in Texas.
- Resource Conservation and Recovery Act (RCRA): RCRA gives the EPA cradle-to-grave authority over hazardous waste. Subtitle C subjects any identified hazardous waste, from on-site generation through transport, treatment, storage, and disposal, to strict federal tracking. Many oilfield wastes are exempt, but mischaracterizing a waste stream on the assumption that an exemption applies, without testing, can lead to severe federal violations.
- Clean Air Act (CAA) and NSPS Quad O: The EPA regulates air emissions under the Clean Air Act, which for oil and gas appears most visibly as 40 CFR Part 60, Subparts OOOOa, OOOOb, and OOOOc (Quad O). These rules mandate emission controls and work practices for new and modified sources, and compliance depends on a well-documented Leak Detection and Repair (LDAR) program.
- Clean Water Act (CWA) and SPCC plans: The Clean Water Act governs discharges of pollutants into United States waters. Any facility that could discharge oil into navigable waters must develop and implement a Spill Prevention, Control, and Countermeasure (SPCC) plan, a proactive engineering and procedural control rather than an after-the-fact penalty.
What does the Railroad Commission of Texas do?
The RRC is the primary energy regulator in Texas, overseeing the exploration, production, and transportation of oil and gas. It frequently gains authority to carry out federal EPA programs at the state level through a process called primacy, which is a key dynamic for operators to understand.
The RRC's implementation of primacy for Class VI injection wells, used for carbon capture and sequestration, is a clear example. The EPA and RRC entered a Memorandum of Agreement transferring primary permitting and enforcement authority to the state, so Texas operators seeking Class VI permits now work directly with the RRC. The EPA retains oversight and sets the minimum criteria the state program must meet, which means an operator must satisfy the RRC's specific requirements while staying aware of the underlying federal standards. For a fuller look at the state rules, see our guide to the RRC Statewide Rules.
Where do EPA and RRC rules overlap and create risk?
The greatest compliance risk sits at the intersection of federal and state jurisdiction. An operator who focuses only on RRC rules can still invite federal enforcement from the EPA. Waste characterization is the classic trap: an operator may manage produced water and drilling muds under the RRC's oil and gas waste rules (16 TAC Chapter 4, which replaced Statewide Rule 8 in July 2025) and believe the operation is fully compliant, but if a waste stream meets the technical definition of hazardous waste under RCRA, because of chemical additives or contaminants, it must be managed under the far more stringent federal system. Relying on the RRC's oilfield-waste exemption without testing and classifying the stream creates real financial and legal exposure.
| Aspect | RRC oil and gas waste rules (16 TAC Ch. 4, formerly Rule 8) | EPA RCRA Subtitle C |
|---|---|---|
| Primary focus | Oil and gas exploration and production (E&P) waste management to protect natural resources. | Cradle-to-grave management of hazardous waste from all industries to protect human health and the environment. |
| "Hazardous" definition | Regulates E&P wastes, many of which are exempt from federal hazardous waste classification. | Defines hazardous waste by specific lists (F, K, P, U) or characteristics (ignitability, corrosivity, reactivity, toxicity). |
| Management requirements | Prescribes methods for storage, transport, and disposal (pits, land farming, injection). | Requires manifests, licensed transporters, permitted treatment/storage/disposal facilities (TSDFs), and extensive record-keeping. |
| Key operator risk | Improper disposal or misapplication of rules leading to state-level violations and remediation costs. | Incorrectly assuming an RRC exemption applies to a stream that meets the EPA's hazardous definition, leading to severe federal fines. |
OSHA complicates the matrix further. It focuses on worker safety, but its Process Safety Management (PSM) and Hazard Communication requirements overlap directly with the EPA's Risk Management Program and RCRA's hazardous-material rules. A failure in one of these areas often signals a failure in all three, which is why a siloed approach to compliance is dangerous.
What are the key steps to an SPCC plan?
Because the SPCC plan is where the Clean Water Act becomes concrete for most operators, it is worth seeing the sequence in one place.
| Step | Action required by operator | Compliance objective |
|---|---|---|
| 1. Facility assessment | Calculate total aboveground oil storage capacity, identify potential spill pathways to navigable waters, and document existing containment. | Determine whether the facility is subject to the SPCC rule (40 CFR Part 112) and establish a baseline. |
| 2. Plan development and certification | Prepare a written plan detailing operating procedures, control measures, and countermeasures. A licensed Professional Engineer must certify the plan if aggregate storage exceeds 10,000 gallons. | Create a defensible, site-specific document that meets federal requirements. |
| 3. Implementation and training | Implement the physical containment and procedural requirements, and conduct annual training for oil-handling personnel. | Keep the plan a living document integrated into daily operations. |
| 4. Review and amendment | Review the plan at least every five years, and amend it within six months of any facility change that materially affects discharge potential. | Maintain plan accuracy as operational conditions change. |
How Tektite helps
The path through this is not memorizing thousands of pages of regulation; it is treating compliance as one integrated function instead of separate silos for air, water, waste, and safety. A fragmented approach, with different vendors handling each area, is exactly how gaps form and how the overlaps between the EPA and RRC get missed. Tektite provides environmental compliance for Texas operators as a single program across EPA, RRC, and OSHA obligations, so an audit by any one agency becomes a check on a process that already works. If you want a clear read on where your operation stands across all three, a focused review is the place to start.

Frequently Asked Questions
What is the difference between the EPA's and the RRC's authority in Texas?
The EPA sets the federal floor for environmental protection through statutes like RCRA, the Clean Air Act, and the Clean Water Act. The Railroad Commission of Texas (RRC) is the state's primary energy regulator and often carries out federal programs at the state level through a process called primacy. In practice an operator answers to both, and the highest risk sits where their jurisdictions overlap.
What are the EPA's main programs for oil and gas operators?
Three federal statutes drive most obligations: RCRA governs hazardous waste from generation to disposal; the Clean Air Act, through NSPS Quad O, controls methane and VOC emissions and drives LDAR programs; and the Clean Water Act requires an SPCC plan for facilities that could discharge oil to navigable waters.
What is regulatory primacy, and how does it work for Class VI wells?
Primacy is the transfer of authority to run a federal program at the state level. Texas operators seeking Class VI carbon-capture injection permits now work directly with the RRC under a Memorandum of Agreement with the EPA. The EPA retains oversight and sets the minimum criteria the state program must meet, so an operator satisfies RRC requirements while staying aware of the underlying federal standards.
When must an SPCC plan be certified by a Professional Engineer?
Under the EPA's SPCC rule (40 CFR Part 112), a facility with more than 10,000 gallons of aggregate aboveground oil storage generally needs a plan certified by a licensed Professional Engineer. Smaller qualified facilities may be able to self-certify a Tier I or Tier II plan. The plan must be reviewed at least every five years and amended within six months of a material facility change.
