(a) If you pay only part of the service charges due for any document filings or only part of the annual maintenance fees, or oil shale fees, for previously-recorded mining claims or sites, or any combination of these fees and charges, absent other instructions from you, BLM will apply the partial payment in serial number order until the money runs out.

(b) For any claims or sites for which there are no funds in your partial payment to pay the maintenance fees, oil shale fees, or location fees, you will forfeit the mining claims or sites not covered by your partial payment unless you submit the additional funds necessary to complete the full payment by the due date.

(c) For any claims or sites for which there are no funds in your partial payment to pay the service charges, BLM will send a notice to you that you must pay the outstanding service charges as described in § 3830.94.
