                        execution of a written statement of need and a

Output: Fracturing Responsibility and Awareness of Chemicals Act or the FRAC Act - Amends the Safe Drinking Water Act to repeal the exemption from restrictions on underground injection of fluids or propping agents granted to hydraulic fracturing operations relating to oil and gas production activities under such Act.

Requires: (1) state underground injection programs to direct a person conducting hydraulic fracturing operations to disclose to the state (or the Administrator if the Administrator has primary enforcement responsibility in such state) the chemicals intended for use in underground injections before the commencement of such operations and the chemicals actually used after the end of such operations; and (2) a state or the Administrator to make such disclosure available to the public.

Requires the applicable person using hydraulic fracturing, when a medical emergency exists and the proprietary chemical formula of a chemical used in such hydraulic fracturing is necessary for medical treatment, to disclose such formula or the specific chemical identity of a trade secret chemical to the state, the Administrator, or the treating physician or nurse upon request, regardless of the existence of a written statement of need or a confidentiality agreement. Authorizes such person to require the execution of such statement and agreement as soon as practicable.
