H.B. No. 4341 establishes a new subchapter in the Government Code focused on emergency response maps for critical infrastructure facilities and creates a grant program to support the development of these maps. The bill defines key terms such as "Division," "Fund," and "Grant program," and specifies that the subchapter applies to public or private airports and military installations. Facilities that receive grants are required to provide accurate emergency response maps to the Texas Division of Emergency Management and relevant public safety agencies, ensuring these maps meet specific standards and are not made available to the public.

The legislation also creates the Critical Infrastructure Emergency Response Map Fund, which will be used to administer the grant program and support the mapping services necessary for compliance with the new requirements. The fund will consist of legislative appropriations, dedicated revenues, and other contributions. The Texas Division of Emergency Management is tasked with establishing the grant program by September 1, 2025, to facilitate the development of these essential emergency response resources.
