If the owner of a farm fails to make the election under this subsection, or fails to timely notify the Secretary of the election as required by subparagraph (B)(iii), the owner shall be deemed to have elected to retain base acres, including generic base acres, as provided in paragraph (2).

(2) Retention of base acres

(A) Election to retain

For the purpose of applying this subchapter to a covered commodity, the Secretary shall give an owner of a farm an opportunity to elect to retain all of the base acres for each covered commodity on the farm.

(B) Treatment of generic base acres

Generic base acres are automatically retained.

(3) Reallocation of base acres

(A) Election to reallocate

For the purpose of applying this subchapter to covered commodities, the Secretary shall give an owner of a farm an opportunity to elect to reallocate all of the base acres for covered commodities on the farm, as in effect on September 30, 2013, among those covered commodities planted on the farm at any time during the 2009 through 2012 crop years.

(B) Reallocation formula

The reallocation of base acres among covered commodities on a farm shall be in proportion to the ratio of—

(i) the 4-year average of—

(I) the acreage planted on the farm to each covered commodity for harvest, grazing, haying, silage, or other similar purposes for the 2009 through 2012 crop years; and

(II) any acreage on the farm that the producers were prevented from planting during the 2009 through 2012 crop years to that covered commodity because of drought, flood, or other natural disaster, or other condition beyond the control of the producers, as determined by the Secretary; to

(ii) the 4-year average of—

(I) the acreage planted on the farm to all covered commodities for harvest, grazing, haying, silage, or other similar purposes for such crop years; and

(II) any acreage on the farm that the producers were prevented from planting during such crop years to covered commodities because of drought, flood, or other natural disaster, or other condition beyond the control of the producers, as determined by the Secretary.

(C) Treatment of generic base acres

Generic base acres are retained and may not be reallocated under this paragraph.

(D) Inclusion of all 4 years in average

For the purpose of determining a 4-year acreage average under subparagraph (B) for a farm, the Secretary shall not exclude any crop year in which a covered commodity was not planted.

(E) Treatment of multiple planting or prevented planting

For the purpose of determining under subparagraph (B) the acreage on a farm that producers planted or were prevented from planting during the 2009 through 2012 crop years to covered commodities, if the acreage that was planted or prevented from being planted was devoted to another covered commodity in the same crop year (other than a covered commodity produced under an established practice of double cropping), the owner may elect the commodity to be used for that crop year in determining the 4-year average, but may not include both the initial commodity and the subsequent commodity.

(F) Limitation

The reallocation of base acres among covered commodities on a farm under this paragraph may not result in a total number of base acres (including generic base acres) for the farm in excess of the number of base acres in effect for the farm on September 30, 2013.

(4) Application of election to all covered commodities

The election made under this subsection, or deemed to be made under paragraph (1)(C), with respect to a farm shall apply to all of the covered commodities on the farm.

(b) Adjustment of base acres

(1) In general

Notwithstanding the election made under subsection (a), the Secretary shall provide for an adjustment, as appropriate, in the base acres for covered commodities for a farm and any generic base acres for the farm whenever any of the following circumstances occur:

(A) A conservation reserve contract entered into under section 1231 of the Food Security Act of 1985 (16 U.S.C. 3831) with respect to the farm expires or is voluntarily terminated.

(B) Cropland is released from coverage under a conservation reserve contract by the Secretary.

(C) The producer has eligible oilseed acreage as the result of the Secretary designating additional oilseeds, which shall be determined in the same manner as eligible oilseed acreage under section 8711(a)(1)(D) of this title.

(2) Special conservation reserve acreage payment rules

For the crop year in which a base acres adjustment under subparagraph (A) or (B) of paragraph (1) is first made, the owner of the farm shall elect to receive price loss coverage or agriculture risk coverage with respect to the acreage added to the farm under this subsection or a prorated payment under the conservation reserve contract, but not both.

(c) Prevention of excess base acres

(1) Required reduction

Notwithstanding the election made under subsection (a), if the sum of the base acres for a farm, including generic base acres, and the acreage described in paragraph (2) exceeds the actual cropland acreage of the farm, the Secretary shall reduce the base acres for 1 or more covered commodities or generic base acres for the farm so that the sum of the base acres, including generic base acres, and the acreage described in paragraph (2) does not exceed the actual cropland acreage of the farm.

(2) Other acreage

For purposes of paragraph (1), the Secretary shall include the following:

(A) Any acreage on the farm enrolled in—

(i) the conservation reserve program established under subchapter B of chapter 1 of subtitle D of title XII of the Food Security Act of 1985 (16 U.S.C. 3831 et seq.); or

(ii) a wetland reserve easement under section 1265C of the Food Security Act of 1985 (16 U.S.C. 3865c).

(3) Selection of acres

The Secretary shall give the owner of the farm the opportunity to select the base acres for a covered commodity or generic base acres for the farm against which the reduction required by paragraph (1) will be made.

(4) Exception for double-cropped acreage

In applying paragraph (1), the Secretary shall make an exception in the case of double cropping, as determined by the Secretary.

(d) Reduction in base acres

(1) Reduction at option of owner

(A) In general

The owner of a farm may reduce, at any time, the base acres for any covered commodity or generic base acres for the farm.

(B) Effect of reduction

A reduction under subparagraph (A) shall be permanent and made in a manner prescribed by the Secretary.

(2) Required action by Secretary

(A) In general

The Secretary shall proportionately reduce base acres, including any generic base acres, on a farm for land that has been subdivided and developed for multiple residential units or other nonfarming uses if the size of the tracts and the density of the subdivision is such that the land is unlikely to return to the previous agricultural use, unless the producers on the farm demonstrate that the land—

(i) remains devoted to commercial agricultural production; or

(ii) is likely to be returned to the previous agricultural use.

(B) Requirement

The Secretary shall establish procedures to identify land described in subparagraph (A).

(3) Treatment of base acres on farms entirely planted to grass or pasture

(A) In general

In the case of a farm on which all of the cropland was planted to grass or pasture (including cropland that was idle or fallow), as determined by the Secretary, during the period beginning on January 1, 2009, and ending on December 31, 2017, the Secretary shall maintain all base acres and payment yields for the covered commodities on the farm, except that no payment shall be made with respect to those base acres under section 9016 or 9017 of this title for the 2019 through 2023 crop years.

The producers on a farm for which all of the base acres are maintained under subparagraph (A) shall be ineligible for the option to change the election applicable to the producers on the farm under section 9015(h) of this title.

(4) Prohibition on reconstitution of farm

The Secretary shall ensure that producers on a farm do not reconstitute the farm to void or change the treatment of base acres under this section.
