§3834.21. How will BLM adjust the location and maintenance fees? — Inbound Citations

(c) If your partial payment for multiple mining claims is submitted in a year in which the BLM adjusts the maintenance fees under § 3834.21, the BLM will apply the partial payment in the amount based on the fee in effect immediately before the adjustment was made to each mining claim or site in serial number order until the money runs out. The BLM will then follow the procedures described in § 3834.23 with respect to each mining claim or site for which the BLM received the full amount of the fee in effect immediately before the adjustment was made. Any underpayment of fees remaining following the expiration of the notice under § 3834.23 is not subject to the partial payment process described in this paragraph.
