a) The owner or operator of surface impoundment units subject to Section 724.321(c) or (d) must have an approved response action plan before receipt of waste. The response action plan must set forth the actions to be taken if the action leakage rate has been exceeded. At a minimum, the response action plan must describe the actions specified in subsection (b).
b) If the flow rate into the LDS exceeds the action leakage rate for any sump, the owner or operator must do the following:
1) Notify the Agency in
writing of the exceedance within seven days after the determination;
2) Submit a preliminary written assessment to
the Agency within 14 days after 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
Agency the results of the determinations specified in subsections (b)(3),
(b)(4), and (b)(5), the results of actions taken, and actions planned. Monthly
thereafter, as long as the flow rate in the LDS exceeds the action leakage
rate, the owner or operator must submit to the Agency a report summarizing the
results of any remedial actions taken and actions planned.
c) To make the leak or remediation determinations in subsections (b)(3), (b)(4), and (b)(5), the owner or operator must do either of the following:
1) Perform
the following assessments:
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 LDS to identify the source
of liquids and possible location 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.
