# §148.1. Purpose, scope and applicability.

- (a) This part identifies wastes that are restricted from disposal into Class I wells and defines those circumstances under which a waste, otherwise prohibited from injection, may be injected.
- (b) The requirements of this part apply to owners or operators of Class I hazardous waste injection wells used to inject hazardous waste.
- (c) Wastes otherwise prohibited from injection may continue to be injected:
  - (1) If an extension from the effective date of a prohibition has been granted pursuant to [§ 148.4](/cfr/40/148.4.md) with respect to such wastes; or
  - (2) If an exemption from a prohibition has been granted in response to a petition filed under [§ 148.20](/cfr/40/148.20.md) to allow injection of restricted wastes with respect to those wastes and wells covered by the exemption; or
  - (3) If the waste is generated by a conditionally exempt small quantity generator, as defined in [§ 261.5](/cfr/40/261.5.md); or
- (d) Wastes that are hazardous only because they exhibit a hazardous characteristic, and which are otherwise prohibited under this part, or [part 268](/cfr/40/part268.md) of this chapter, are not prohibited if the wastes:
  - (1) Are disposed into a nonhazardous or hazardous injection well as defined under [40 CFR § 146.6(a)](/cfr/40/146.6.md?p=a); and
  - (2) Do not exhibit any prohibited characteristic of hazardous waste identified in [40 CFR part 261](/cfr/40/part261.md), [subpart C](/cfr/40/subpartC.md) at the point of injection.
