monitored monthly for releases in accordance with a method specified in Section
16(b) through (k); or
(C) Another

compliance with the requirements of this section.
(b) All owners and/or operators of repaired UST
systems shall ensure the modifications meet the performance standards for
design and repair, as set forth in Section 6.
(c) Costs associated with remediation of any release
