“SEC. 17. LEASING OF OIL AND GAS PARCELS.
“(a) Leasing Authorized.—
“(1) In general.—Any parcel of land subject to disposition under this Act that is known or believed to contain oil or gas deposits shall be made available for leasing, subject to paragraph (2), by the Secretary of the Interior, not later than 18 months after the date of receipt by the Secretary of an expression of interest in leasing the applicable parcel of land available for disposition under this section, if the Secretary determines that the parcel of land is open to oil or gas leasing under the approved resource management plan applicable to the planning area in which the parcel of land is located that is in effect on the date on which the expression of interest was submitted to the Secretary (referred to in this subsection as the ‘approved resource management plan’).
“(2) Resource management plans.—
“(A) Lease terms and conditions.—A lease issued by the Secretary under this section with respect to an applicable parcel of land made available for leasing under paragraph (1)—
“(i) shall be subject to the terms and conditions of the approved resource management plan; and
“(ii) may not require any stipulations or mitigation requirements not included in the approved resource management plan.
“(B) Effect of amendment.—The initiation of an amendment to an approved resource management plan shall not prevent or delay the Secretary from making the applicable parcel of land available for leasing in accordance with that approved resource management plan if the other requirements of this section have been met, as determined by the Secretary.”
“(4) Term.—A permit to drill approved under this subsection shall be valid for a single, non-renewable 4-year period beginning on the date that the permit to drill is approved.”
; and
“(q) Commingling of Production.—The Secretary of the Interior shall approve applications allowing for the commingling of production from 2 or more sources (including the area of an oil and gas lease, the area included in a drilling spacing unit, a unit participating area, a communitized area, or non-Federal property) before production reaches the point of royalty measurement regardless of ownership, the royalty rates, and the number or percentage of acres for each source if the applicant agrees to install measurement devices for each source, utilize an allocation method that achieves volume measurement uncertainty levels within plus or minus 2 percent during the production phase reported on a monthly basis, or utilize an approved periodic well testing methodology. Production from multiple oil and gas leases, drilling spacing units, communitized areas, or participating areas from a single wellbore shall be considered a single source. Nothing in this subsection shall prevent the Secretary of the Interior from continuing the current practice of exercising discretion to authorize higher percentage volume measurement uncertainty levels if appropriate technical and economic justifications have been provided.”
