Creates new provisions related to the construction of data centers

HB 3390 establishes new regulations for hyperscale data centers in Missouri, defined as facilities using at least 25 megawatts of energy. It prohibits these centers on agricultural, conservation, and residential land categories after August 28, 2026, and requires a 500-foot setback using native plants. The bill mandates noise control measures during construction, compliance with federal noise standards, and a public hearing process for local approvals. A new state Siting Board must review projects after local government approval, and developers cannot charge residential or commercial customers impact fees tied to the data center's energy use.
