State Government - As introduced, creates the "Tennessee Critical Infrastructure Act." - Amends TCA Title 4.

SB 378, the "Tennessee Critical Infrastructure Protection Act," prohibits foreign adversaries from accessing or controlling Tennessee's critical infrastructure - including power grids, water systems, telecommunications, and transportation networks - by banning agreements that would allow such access. It directly affects companies and government entities managing these systems, requiring them to certify their access, conduct background checks on employees with infrastructure access, and ban foreign nationals from adversary nations. Exceptions are permitted only if no alternative exists, the contract is pre-approved by the state, and the risk of non-approval outweighs the security threat. The bill establishes new registration requirements, fees, and security protocols to prevent foreign interference in essential state infrastructure.
