# §725.56. Extension of the review period.

- (a) At any time during the review period, EPA may unilaterally determine that good cause exists to extend the review period specified for MCANs, or the exemption requests.
- (b) If EPA makes such a determination, EPA:
  - (1) Will notify the submitter that EPA is extending the review period for a specified length of time and state the reasons for the extension.
  - (2) For MCANs, EPA may issue a notice for publication in the Federal Register which states that EPA is extending the review period and gives the reasons for the extension.
- (c) The total period of the extension may be for a period of up to the same length of time as specified for each type of submission in [§ 725.50](/cfr/40/725.50.md). If the initial extension is for less than the total time allowed, EPA may make additional extensions. However, the sum of the extensions may not exceed the total allowed.
- (d) The following are examples of situations in which EPA may find that good cause exists for extending the review period:
  - (1) **EPA has reviewed the submission and is seeking additional information.**
  - (2) **EPA has received significant additional information during the review period.**
  - (3) The submitter has failed to correct a submission after receiving EPA's request under [§ 725.32](/cfr/40/725.32.md).
  - (4) EPA has reviewed the submission and determined that there is a significant possibility that the microorganism will be regulated under [section 5(e)](/cfr/40/5.md?p=e) or section 5(f) of the Act, but EPA is unable to initiate regulatory action within the initial review period.
