Public Records - As enacted, designates records of the office of homeland security related to critical infrastructure as confidential and exempts such records from public records requests; makes related changes. - Amends TCA Title 10, Chapter 7, Part 5.

HB 1640 would amend Tennessee's public records law to make specific records held by the Office of Homeland Security confidential. It directly affects public access to records related to critical infrastructure security, including threat analyses, infrastructure protection plans, and responses to security threats. The bill exempts three categories of records from disclosure: those describing protected critical infrastructure, records about preventing or responding to threats against infrastructure, and records designated confidential by the commissioner. This change would prevent public requests for these specific homeland security documents under Tennessee's open records law. The bill is currently pending review by the State & Local Government Committee.
