7 C.F.R. § 1980.405
The business financed with a B&I loan must be located in a rural area. Loans to borrowers with facilities located in both rural and non-rural areas will be limited to the amount necessary to finance the facility located in the eligible rural area. Cooperatives that are headquartered in a non-rural area may be eligible for a B&I loan if the loan is used for a project or venture that is located in a rural area. Rural areas are any areas other than a city or town that has a population of greater than 50,000 inhabitants, the urbanized area contiguous and adjacent to such a city or town, as defined by the U.S. Bureau of the Census, and which exclude certain populations pursuant to 7 U.S.C. 1991(a)(13)(H) and (I). For the purpose of this section:
