# §147.3003. Aquifer exemptions.

- (a) **Aquifer exemptions in connection with Class II wells.** In accordance with [§ 144.7(b)](/cfr/40/144.7.md?p=b) and [§ 146.4](/cfr/40/146.4.md) of this chapter, the portions of authorized injection zones into which existing Class II wells are currently injecting which are described in appendix A are hereby exempted. The exempted aquifers are defined by a one-quarter mile radius from the existing injection well. The exemption includes the intended injection zone only and is solely for the purpose of Class II injection.
- (b) **Class III wells.** In addition to the requirements of [§ 144.7(c)(1)](/cfr/40/144.7.md?p=c-1) of this chapter, an applicant for a uranium mining permit which necessitates an aquifer exemption shall submit a plugging and abandonment plan containing an aquifer cleanup plan, acceptable to the Director, describing the methods or techniques that will be used to meet the standards of [§ 147.3011](/cfr/40/147.3011.md). The cleanup plan shall include an analysis of pre-injection water quality for the constituents required by the Director. The Director shall consider the cleanup plan in addition to the other information required for permit applications under §§ [144.31(e)](/cfr/40/144.31.md?p=e) and [146.34](/cfr/40/146.34.md) of this chapter.
