What is the basic time limit for responding to a request?

(a) Ordinarily, the bureau has 20 workdays (including the date of receipt) to determine whether to comply with a request, but unusual circumstances may allow the bureau to take longer than 20 workdays (see § 2.19 of this subpart). (b) A consultation or referral under § 2.13 of this part does not restart the statutory time limit for responding to a request. [77 FR 76902, Dec. 31, 2012, as amended at 81 FR 11128, Mar. 3, 2016]
