(B) The director of each agency that is the custodian of information, the unrestricted release of which could increase the risk of acts of terrorism, may identify the information or compilations of information by notifying the Attorney General in writing, and shall promulgate regulations in accordance with the Administrative Procedures Act, §§ 1-23-110 through 1-23-120(a) and § 1-23-130, to regulate access to the information in accordance with the provisions of this section.
(C) Regulations to govern access to information subject to subsections (A) and (B) must at a minimum provide for:
(1) disclosure of information to state, federal, and local authorities as required to carry out governmental functions; and
(2) disclosure of information to persons who live or work within a vulnerable zone.
For purposes of this section, "vulnerable zone" is defined as a circle, the center of which is within the boundaries of a facility possessing hazardous, toxic, flammable, radioactive, or infectious materials subject to this section, and the radius of which is that distance a hazardous, toxic, flammable, radioactive, or infectious cloud, overpressure, radiation, or radiant heat would travel before dissipating to the point it no longer threatens serious short-term harm to people or the environment.
Disclosure of information pursuant to this subsection must be by means that will prevent its removal or mechanical reproduction. Disclosure of information pursuant to this subsection must be made only after the custodian has ascertained the person’s identity by viewing photo identification issued by a federal, state, or local government agency to the person and after the person has signed a register kept for the purpose.
