H.B. No. 4341 establishes a new framework for emergency response maps related to critical infrastructure facilities in Texas, specifically focusing on public or private airports and military installations. The bill introduces Subchapter D to Chapter 424 of the Government Code, which includes definitions for key terms such as "Division," "Fund," and "Grant program." It mandates that applicable critical infrastructure facilities must provide accurate emergency response maps to the Texas Division of Emergency Management and relevant public safety agencies. These maps must adhere to specific standards, including detailed floor plans and the identification of hazards and critical utilities, while ensuring accessibility for emergency responders.

Additionally, the bill creates a critical infrastructure emergency response map grant program, which will be administered by the Texas Division of Emergency Management. This program will provide funding for mapping services to develop the required emergency response maps. The newly established critical infrastructure emergency response map fund will consist of legislative appropriations, dedicated revenues, and other contributions, and will be used exclusively for administering the grant program. The act is set to take effect on September 1, 2025, and aims to enhance emergency preparedness and response capabilities for critical infrastructure in Texas.
