# §124.211. What types of changes may I make to my standardized permit?


You may make both routine changes, routine changes with prior Agency approval, and significant changes. For the purposes of this section:

- (a) “Routine changes” are any changes to the standardized permit that qualify as a class 1 permit modification (without prior Agency approval) under [40 CFR 270.42](/cfr/40/270.42.md), appendix I, and
- (b) “Routine changes with prior Agency approval” are for those changes to the standardized permit that would qualify as a class 1 modification with prior agency approval, or a class 2 permit modification under [40 CFR 270.42](/cfr/40/270.42.md), appendix I; and
- (c) “Significant changes” are any changes to the standardized permit that:
  - (1) Qualify as a class 3 permit modification under [40 CFR 270.42](/cfr/40/270.42.md), appendix I;
  - (2) Are not explicitly identified in [40 CFR 270.42](/cfr/40/270.42.md), appendix I; or
  - (3) **Amend any terms or conditions in the supplemental portion of your standardized permit.**
