Section 37.5 - Collection of information(a) The collections of information contained in this part have been approved by the Office of Management and Budget under 44 U.S.C. 3501 et seq. and assigned clearance numbers 1004-0165 (cave nominations) and 1004-0166 (confidential information). The information provided for the cave nominations will be used to determine which caves will be listed as "significant" and the information in the requests to obtain confidential cave information will be used to decide whether to grant access to this information. Response to the call for cave nominations is voluntary. No action may be taken against a person for refusing to supply the information requested. Response to the information requirements for obtaining confidential cave information is required to obtain a benefit in accordance with Section 5 of the Federal Cave Resources Protection Act of 1988 (102 Stat. 4546; 16 U.S.C. 4301 ).(b) The public reporting burden is estimated to average 3 hours per response for the cave nomination and one-half hour per response for the confidential cave information request. The estimated response time for both of the information burdens includes time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection of information. Send comments regarding this burden estimate or any other aspect of this collection of information, including suggestions for reducing the burden, to Bureau of Land Management Clearance Officer, WO-873, Mail Stop 401 LS, 1849 C Street NW., Washington, DC 20240; and the Office of Management and Budget, Paperwork Reduction Project 1004-0165/6, Washington, D.C. 20503.
