# 18.104 How the FWS will evaluate a request for an LOA.

(a) The FWS will evaluate each request for an LOA to determine if the specified activity is consistent with the analysis and findings we made during the rulemaking process for this subpart.

(1) We will determine whether the level of activity identified in the request exceeds the level that we analyzed in estimating the number of animals to be taken and evaluating whether there will be a negligible impact on the species or stock and an unmitigable adverse impact on the availability of the species or stock for subsistence uses.

(2) If the level of activity is greater, we will evaluate the potential impact of this greater level of activity to determine if the potential impact is consistent with our findings. Depending on the results of the evaluation, we may grant the requested authorization, add further conditions, or deny the request for an LOA. An LOA will be limited to a 1-year period or less within the period set forth in § 18.102.

(b) The FWS will make decisions concerning withdrawal or suspension of an LOA (see § 18.27(f)(5) and (6)).
