(a)
The owner or operator of surface impoundment units subject to section
66265.221(a)
shall submit a response action plan to the Department when submitting the
proposed action leakage rate under section
66265.222. The response action
plan shall set forth the actions to be taken if the action leakage rate has
been exceeded. At a minimum, the response action plan shall describe the
actions specified in subsection (b) of this section.
(b) If the flow rate into the leak detection
system exceeds the action leakage rate for any sump, the owner or operator
shall:
(1) Notify the Department in writing
of the exceedence within 7 days of the determination;
(2) Submit a preliminary written assessment
to the Department within 14 days of the determination, as to the amount of
liquids, likely sources of liquids, possible location, size, and cause of any
leaks, and short-term actions taken and planned;
(3) Determine to the extent practicable the
location, size, and cause of any leak;
(4) Determine whether waste receipt should
cease or be curtailed, whether any waste should be removed from the unit for
inspection, repairs, or controls, and whether or not the unit should be
closed;
(5) Determine any other
short-term and longer-term actions to be taken to mitigate or stop any leaks;
and
(6) Within 30 days after the
notification that the action leakage rate has been exceeded, submit to the
Department the results of the analyses specified in subsections (b)(3), (4),
and (5) of this section, the results of actions taken, and actions planned.
Monthly thereafter, as long as the flow rate in the leak detection system
exceeds the action leakage rate, the owner or operator shall submit to the
Department a report summarizing the results of any remedial actions taken and
actions planned.
(c) To
make the leak and/or remediation determinations in subsections (b)(3), (4), and
(5) of this section, the owner or operator shall:
(1)
(A)
Assess the source of liquids and amounts of liquids by source,
(B) Conduct a fingerprint, hazardous
constituent, or other analyses of the liquids in the leak detection system to
identify the source of liquids and possible locations of any leaks, and the
hazard and mobility of the liquid; and
(C) Assess the seriousness of any leaks in
terms of potential for escaping into the environment; or
(2) Document why such assessments are not
needed.
