(a) For eligible crops insured under an APH or yield-based plans and insured crops in Puerto Rico, the eligible acres for Stage 2 payment calculation will be the eligible acres as specified in the applicable insurance provisions.

(b) For eligible crops other than those covered under an APH or yield-based plan or insured in Puerto Rico, eligible acres will be determined based on the following provisions:

(1) Eligible acreage will be calculated using the lesser of the reported or determined acres shown to have been planted or prevented from being planted to a crop.

(2) Initial crop acreage will be the acreage used to calculate payments under this subpart, unless the provisions for subsequent crops in this section are met. Subsequently planted or prevented planted acreage is considered acreage under this subpart only if the provisions of this section are met. All plantings of an annual or biennial crop are considered the same as a planting of an initial crop in tropical regions as defined in part 1437, subpart F, of this title.

(3) In cases where there is double cropped acreage, each crop may be included in the acreage only if the specific crops are approved by FSA as eligible double cropping practices.

(4) Except for insured crops, participants with double cropped acreage not meeting the criteria in paragraph (b)(3) of this section may have such acreage included in the acreage for more than one crop only if the participant submits verifiable records establishing a history of carrying out a successful double cropping practice on the specific crops for which payment is requested.

(5) Participants having multiple plantings may receive payments for each planting only if the planting meets the requirements of part 1437 of this title.

(c) For prevented planting, the provisions of parts 718 and 1437 of this title specifying what is considered prevented planting and how it must be documented and reported apply. Crops located in tropical regions are not eligible for prevented planting.

(d) For SDRP Stage 2:

(1) 2023, 2024, and 2025 crop year uninsured prevented planting acres are eligible acres if they meet all requirements of this subpart; and

(2) 2023, 2024, and 2025 crop year insured and NAP-covered prevented planting acres are not eligible acres.

(e) FSA will:

(1) Use the most accurate data available when determining planted and prevented planted acres; and

(2) Disregard acreage of a crop produced on land that is not eligible for Federal crop insurance or NAP.

(f) In cases where crops were insured by an area plan, producers must provide the eligible acreage percentage to FSA for payment. This represents the percentage of eligible acreage of eligible crops compared to the total acreage insured under the respective Area Plan. It is determined by the producer based on a comparison of RMA acres provided on the FSA-504 and total acres reported for the eligible crop on the FSA-578. This percentage excludes acres of grazed crops covered by an Annual Forage policy. This percentage will also exclude acreage that was physically located in a county in Connecticut, Hawaii, Maine, or Massachusetts.
