# §351.302. Extension of time limits; return of untimely filed or unsolicited material.

- (a) **Introduction.** This section sets forth the procedures for requesting an extension of a time limit. In addition, this section explains that certain untimely filed or unsolicited material will be rejected together with an explanation of the reasons for the rejection of such material.
- (b) **Extension of time limits.** Unless expressly precluded by statute, the Secretary may, for good cause, extend any time limit established by this part.
- (c) **Requests for extension of specific time limit.** Before the applicable time limit established under this part expires, a party may request an extension pursuant to [paragraph (b)](#b) of this section. An untimely filed extension request will not be considered unless the party demonstrates that an extraordinary circumstance exists. The request must be in writing, in a separate, stand-alone submission, filed consistent with [§ 351.303](/cfr/19/351.303.md), and state the reasons for the request. An extension granted to a party must be approved in writing.
  - (1) An extension request will be considered untimely if it is received after the applicable time limit expires or as otherwise specified by the Secretary.
  - (2) **An extraordinary circumstance is an unexpected event that—**
    - (i) Could not have been prevented if reasonable measures had been taken, and
    - (ii) Precludes a party or its representative from timely filing an extension request through all reasonable means.
- (d) **Rejection of untimely filed or unsolicited material.**
  - (1) Unless the Secretary extends a time limit under [paragraph (b)](#b) of this section, the Secretary will not consider or retain in the official record of the proceeding:
    - (i) Untimely filed factual information, written argument, or other material that the Secretary rejects, except as provided under [§ 351.104(a)(2)](/cfr/19/351.104.md?p=a-2); or
    - (ii) Unsolicited questionnaire responses, except as provided for voluntary respondents under [§ 351.109(h)(2)](/cfr/19/351.109.md?p=h-2).
  - (2) The Secretary will reject such information, argument, or other material, or unsolicited questionnaire response with, to the extent practicable, written notice stating the reasons for rejection.
