Class V Injection Wells Regulated by the TCEQ

Process for obtaining a permit for Class V injection wells, which apply to a wide variety of activities that release water or another liquid into the ground. Links to relevant forms and rules.

 

If you are interested in applying for a new or modifying an existing Class V authorization regulated by the TCEQ, you are encouraged to contact the TCEQ’s Underground Injection Control Program before you submit an authorization form. In such communications, TCEQ personnel will supply any information relevant to your application, including the following:

After the application is received, technical review will be conducted, including some of the following tasks, depending on the type of well:

  • Our staff will review the geohydrologic and engineering aspects of the proposed well facility;
  • you, as the applicant, may receive a request for additional information;
  • if your application is complete and compliant with applicable rules and statutes, a letter of approval will be sent to you;
  • if your application is incomplete or not compliant with the applicable rules, you will receive a letter outlining the deficiencies and you may contact TCEQ staff to discuss the application and your possible alternatives; and
  • the executive director may require the owner or operator of an injection well authorized by rule to apply for and obtain an injection well permit. The owner or operator shall submit a complete application within 90 days after the receipt of a letter from the executive director requesting that the owner or operator of an injection well submit an application for permit. Cases for which a permit may be required include, but are not limited to, wells not in compliance with the standards required by 30 TAC 331.9.

Please feel free to contact us if you have questions.

Class IV Injection Wells

Information about restrictions for Class IV injection wells, which are allowed only in special circumstances involving environmental cleanups.

Class IV injection wells are generally banned by state and federal statutes and rules. However, under TCEQ and EPA rules, a Class IV well may be authorized for use in certain environmental cleanup operations. If you think you qualify for use of a Class IV well for authorized cleanup, you should schedule a meeting with TCEQ to discuss the situation. Applications for Class IV wells will be made by using the Class V injection well authorization forms

Please feel free to contact us if you have questions.

Injection Wells: Am I Regulated?

Information about injection wells and regulations for them in Texas. Links to more guidance and forms for specific regulatory programs.

Chapter 27Exit TCEQ of the Texas Water Code (the Injection Well Act) defines an “injection well” as “an artificial excavation or opening in the ground made by digging, boring, drilling, jetting, driving, or some other method, and used to inject, transmit, or dispose of industrial and municipal waste or oil and gas waste into a subsurface stratum; or a well initially drilled to produce oil and gas which is used to transmit, inject, or dispose of industrial and municipal waste or oil and gas waste into a subsurface stratum; or a well used for the injection of any other fluid; but the term does not include any surface pit, surface excavation, or natural depression used to dispose of industrial and municipal waste or oil and gas waste.” All injection wells are regulated by either TCEQ (the commission in the Act) or the Railroad Commission of TexasExit TCEQ (RRC). Injection wells are classified into five different types:

  • Class I wells, which are used for deep injection, are regulated by the TCEQ. (The RRC reviews and comments on these applications.)
  • Class II wells, which are related to energy byproducts, are regulated by the RRC.
  • Class III wells, which are used to extract minerals other than oil and gas, are regulated by the TCEQ or the RRC, depending on the type of well.
  • Class IV wells are generally banned, but may be authorized by the TCEQ or the EPA in certain environmental cleanup operations.
  • Class V wells, which are used for many different activities, are regulated by either the TCEQ or the RRC, depending on the type of well.

A few examples of injection wells regulated by the TCEQ are:

  • Wells that inject municipal, industrial, or hazardous wastes into a layer that is below the lowermost underground source of drinking water
  • Wells that inject fluids to extract uranium or sulfur and to get rid of waste byproducts from the mining operation
  • Wells that inject hazardous waste above an underground source of drinking water
  • Any well or similar apparatus that releases a liquid or liquids into or above an underground source of drinking water

If you are still not sure whether you are regulated, read the EPA’s UIC Pocket Guide #2Exit TCEQ or contact us.

The Permit Process for Class I Injection Well Applications:

After the application is received, it will be reviewed for administrative completeness. If the application is declared administratively complete, a technical review will be conducted including the following tasks:

  • Staff will review the geohydrologic and engineering aspects of the proposed well facility;
  • You may receive a request for additional information called a Notice of Deficiency;
  • A proposed draft permit will be prepared for technically complete applications and sent to you as the applicant;
  • A technical summary, a compliance history and a notice of draft permit will be prepared;
  • If the application is deemed complete and compliant with the appropriate rules and statutes, notice will be given. To encourage public participation in the permit process, TCEQ's Executive Director will prepare and the Chief Clerk will mail a Notice of Application and Intent to Obtain a Permit and a Notice of Application and Preliminary Decision;
  • You as the applicant are responsible for publishing the notice in the appropriate news media (please check to see if you also need to publish notice in an alternate language);
  • After each notice, the executive director receives comments and responds to all significant comments. A public meeting may be held;
  • Certain persons which could potentially be affected by the injection well may request a public meeting and hearing prior to a decision being made on an injection well permit application;
  • The executive director will decide if the permit should be issued if the application is complete and compliant with applicable rules and statutes, and is uncontested;
  • If the application is contested, the Commission will issue the permit or deny the application after any legal appeals are complete;
  • The executive director's decision can be appealed to the Commission; and
  • You will receive your permit after the executive director's decision, and, on those occasions in which a hearing process is required, any appeals are exhausted.
  • Well owners are resposible for proper closure and post closure care for their well(s). Financial assurance shall be submitted at least 60 days prior to commencement of drilling operations for new wells and for salt cavern disposal wells.
  • Within 90 days after the completion or conversion of the well, the permittee shall submit a Completion Report to the executive director. The report must include a surveyor's plat showing the exact location and giving the latitude and longitude of the well. The report must also include a certification that a notation on the deed to the facility property or on some other instrument which is normally examined during title search has been made stating the surveyed location of the well, the well permit number, and its permitted waste streams

The Class I UIC General Permit:

The Class I UIC General Permit WDWG010000 provides authorization for use of a Class I injection well to inject nonhazardous brine from a desalination operation or nonhazardous drinking water treatment residuals. To obtain authorization to construct and operate a Class I well under the General Permit you must submit a Notice of Intent.

Notice of Intent
Class I UIC General Permit WDWG010000

The Permit Process for Wells to be Authorized under the UIC General Permit WDWG010000:

  • After a Notice of Intent (NOI) is received, staff will conduct an administrative review of the NOI to check it for completeness.
  • Staff will review the financial assurance amount in the NOI and the financial assurance mechanism.
  • If you, as the applicant, are an existing facility, staff will check your compliance history.
  • You may receive a request for additional information called a Notice of Deficiency.
