Yes. Sodium leases authorize you to mine potassium compounds as related products, and potassium leases authorize mining associated sodium compounds and related products. A phosphate lease allows you to use deposits of silica, limestone or other rock on the lease for use in the processing or refining of phosphate, phosphate rock, and associated minerals mined from the leased lands. You must pay royalty on these materials as specified in your lease.

Yes. If you are producing calcium chloride in paying quantities from an existing mine which you control, you may apply to BLM for a noncompetitive lease to produce the commingled sodium chloride. You must already have authorization, under part 3800 of this chapter, for the locatable minerals. You must also meet the other requirements of this part for the commingled leasable minerals.

Yes. BLM will issue your lease on a standard form which will contain several terms and conditions. We will add your rental rate, royalty obligations and any special stipulations to this lease form.

(a) If your lease is issued subject to readjustment, BLM will notify you of the readjusted terms before the end of each 20-year period. If we do not timely notify you of readjusted terms, those leases continue for another 20-year period under the same terms and conditions.

(b) If you have a lease that requires renewal, we will issue the lease for an initial term as specified in § 3510.15 of this part. You must apply for a renewal of the lease at least 90 days before the initial term ends in order to extend the lease for an additional term. If you do not renew the lease, it expires and the lands become available for re-leasing. BLM may change some of your lease terms when we renew a lease.

(a) You have 60 days after receiving the proposed readjusted terms to object. If we do not receive your objection within 60 days, the proposed readjusted terms will be in effect. If you file an objection, BLM will issue a decision in response. If you disagree with the decision, you may appeal under parts 4 and 1840 of this title.

(b) The readjusted lease terms and conditions will be effective pending the outcome of any appeal, unless BLM provides otherwise.

File an application at least 90 days before the lease term expires. No specific form is required. Send us 3 copies of your application together with the processing fee for lease renewal found in the fee schedule in § 3000.12 of this chapter and an advance rental payment of $1 per acre or fraction of an acre.

Yes. Continue to pay royalties and rentals at the original rate. Your obligation to pay any increased readjusted royalties, minimum royalties and rentals will be suspended while your appeal is considered. However, any increased charges accrue beginning with the effective date of the readjustment or renewal, while final action on your appeal is pending. If the increased charges are sustained on appeal, you must pay the accrued balance, plus interest at the rate MMS specifies for late payment in 30 CFR part 218.
