To amend the Homeland Security Act of 2002 to exclude certain propane storage facilities from certain chemical security standards under the Department of Homeland Security, and for other purposes.

HR 1623 amends the Homeland Security Act to exclude specific propane storage facilities from certain Department of Homeland Security chemical security standards. It directly affects facilities storing propane for residential use (as defined in the Fair Housing Act), agricultural production (per CFR), or small rural businesses (per the Small Business Act). The bill adds a new exclusion criterion for these facilities and requires the DHS Secretary to report to Congress and notify owners if a facility doesn't qualify for the exclusion. This changes the current security requirements for these specific propane storage locations without altering broader DHS chemical security rules.
