Ill. Admin. Code tit. 35 § 704.280
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.
