Terms not defined in this section have the meaning given by the appropriate Act. When a defined term appears in a definition, the defined term is sometimes placed within quotation marks as an aid to readers.
means the Administrator of the United States Environmental Protection Agency, or an authorized representative.
means the EPA standard national forms for applying for a permit, including any additions, revisions or modifications to the forms; or forms approved by EPA for use in approved States, including any approved modifications or revisions.
Appropriate Act and regulations
means the Solid Waste Disposal Act, as amended by the Resource Conservation and Recovery Act (RCRA); or Safe Drinking Water Act (SDWA), whichever is applicable; and applicable regulations promulgated under those statutes.
Approved State Program
means a UIC program administered by the State or Indian Tribe that has been approved by EPA according to SDWA sections 1422 and/or 1425.
means a geological "formation," group of formations, or part of a formation that is capable of yielding a significant amount of water to a well or spring.
Area of review
means the area surrounding an injection well described according to the criteria set forth in §146.06 or in the case of an area permit, the project area plus a circumscribing area the width of which is either 1/4 of a mile or a number calculated according to the criteria set forth in §146.06.
means a "drywell" that receives untreated sanitary waste containing human excreta, and which sometimes has an open bottom and/or perforated sides.
means any physical, chemical, biological, or radiological substance or matter in water.
means the Regional Administrator, the State director or the Tribal director as the context requires, or an authorized representative. When there is no approved State or Tribal program, and there is an EPA administered program, Director means the Regional Administrator. When there is an approved State or Tribal program, "Director" normally means the State or Tribal director. In some circumstances, however, EPA retains the authority to take certain actions even when there is an approved State or Tribal program. In such cases, the term Director means the Regional Administrator and not the State or Tribal director.
means a document prepared under §124.6 indicating the Director's tentative decision to issue or deny, modify, revoke and reissue, terminate, or reissue a "permit." A notice of intent to terminate a permit, and a notice of intent to deny a permit, as discussed in §124.5 are types of "draft permits." A denial of a request for modification, revocation and reissuance, or termination, as discussed in §124.5 is not a "draft permit."

means an "injection well" other than a "new injection well."
Facility or activity
means any UIC "injection well," or an other facility or activity that is subject to regulation under the UIC program.
means any material or substance which flows or moves whether in a semisolid, liquid, sludge, gas, or any other form or state.
means a body of consolidated or unconsolidated rock characterized by a degree of lithologic homogeneity which is prevailingly, but not necessarily, tabular and is mappable on the earth's surface or traceable in the subsurface.
means "fluid" present in a "formation" under natural conditions as opposed to introduced fluids, such as "drilling mud."
means any person, by site location, whose act or process produces hazardous waste identified or listed in 40 CFR Part 261.
Geologic sequestration means the long-term containment of a gaseous, liquid, or supercritical carbon dioxide stream in subsurface geologic formations. This term does not apply to carbon dioxide capture or transport.

means a naturally occurring karst depression or other natural crevice found in volcanic terrain and other geologic settings which have been modified by man for the purpose of directing and emplacing fluids into the subsurface.
means "Indian country" as defined in 18 U.S.C. 1151. That section defines Indian country as:
(a) All land within the limits of any Indian reservation under the jurisdiction of the United States government, notwithstanding the issuance of any patent, and, including rights-of-way running through the reservation;
(b) All dependent Indian communities within the borders of the United States whether within the original or subsequently acquired territory thereof, and whether within or without the limits of a State; and
(c) All Indian allotments, the Indian titles to which have not been extinguished, including rights-of-way running through the same.
means any Indian Tribe having a Federally recognized governing body carrying out substantial governmental duties and powers over a defined area.
means a "well" into which "fluids" are being injected.
means a geological "formation" group of formations, or part of a formation receiving fluids through a "well."
means an agency of two or more States established by or under an agreement or compact approved by the Congress, or any other agency of two or more States or Indian Tribes having substantial powers or duties pertaining to the control of pollution as determined and approved by the Administrator under the "appropriate Act and regulations."
means any UIC "facility or activity" classified as such by the Regional Administrator, or, in the case of approved State programs, the Regional Administrator in conjunction with the State Director.
means the shipping document originated and signed by the "generator" which contains the information required by Subpart B of 40 CFR Part 262.

Owner or operator
means the owner or operator of any "facility or activity" subject to regulation under the UIC program.
means an authorization, license, or equivalent control document issued by EPA or an approved State to implement the requirements of this part, Parts 145, 146 and 124.

means the last accessible sampling point prior to waste fluids being released into the subsurface environment through a Class V injection well. For example, the point of injection of a Class V septic system might be the distribution box—the last accessible sampling point before the waste fluids drain into the underlying soils. For a dry well, it is likely to be the well bore itself.
means the act or process of stopping the flow of water, oil or gas into or out of a formation through a borehole or well penetrating that formation.
