Under existing statutory or regulatory authority or through the establishment of new authority by executive or legislative action, for all existing chemical manufacturing and storage facilities that:
(1) Are located in a hurricane-prone region as defined by the International Building Code, and
(2) Manufacture or store or can inadvertently or otherwise produce (e.g., by chemical reaction) regulated substances inside equipment or building(s) built before more current wind design requirements came into effect
Require the facility operators to evaluate the hazards to their facilities from hurricanes and accompanying wind, rainwater, floodwater, or storm surge forces. Require the facility operators to implement processes and safeguards for protection against those hazards, such as through:
a. Ensuring that buildings and structures (both new and existing) can withstand hurricane winds and flooding, with a particular focus on buildings and structures containing hazardous materials;
b. Implementing safeguards and processes to ensure that hazardous chemicals are not compromised and released during extreme weather events; and/or
c. Following the guidance presented in the Center for Chemical Process Safety Monograph Assessment of and Planning for Natural Hazards.
