(2) Use another option determined by the implementing agency to be no less protective of human health and the environment than the options listed in paragraph (b)(1) of this section.

(c) Owners and operators must maintain records in accordance with § 280.34(b) documenting compliance with paragraph (b) of this section for as long as the UST system is used to store the regulated substance.
