Definition of a Class V Injection Well

Section 704 Section 704.280  Definition of a Class V Injection Well Section 704.106 defines the six classes of injection wells, including a Class V injection well, as regulated under this Subpart I.  Typically, Class V injection wells are shallow wells used to place a variety of fluids directly below the land surface.  However, if the fluids placed in the ground qualify as a hazardous waste under RCRA, the well is either a Class I or Class IV injection well, not a Class V injection well.  Similarly, a carbon sequestration well is a Class VI injection well (or a Class II injection well under specified circumstances), not a Class V injection well.  Examples of Class V injection wells are described in Section 704.281.
