This bill would prohibit federal agencies from providing financial assistance to data center projects built on prime farmland or other protected agricultural land. The legislation applies to construction, expansion, or substantial rehabilitation of data centers that begins after the bill's enactment and covers various forms of federal support including grants, loans, tax credits, tax deductions, and accelerated depreciation allowances. The restriction targets land classified as prime or unique farmland under the Farmland Protection Policy Act. The bill would affect technology companies and data center developers seeking federal incentives for projects on agricultural land, as well as states and localities that might have offered such incentives in coordination with federal programs. No specific funding is allocated in the bill, as it is a prohibition rather than an appropriation measure.
