BLM determines the rate for each lease before we offer it. If BLM offered the lease competitively, the rates are in the notice of lease sale. If you applied for a noncompetitive lease, BLM will send you a royalty rate schedule for your concurrence and signature before we issue you the lease. BLM attaches royalty rates to, and makes them a part of, all leases.
