Current through Register Vol. 50, No. 9, September 20, 2024
A. The
owner or operator of landfill units subject to LAC 33:V.2503.L or M 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 LAC 33:V.2508.B.
B. If
the flow rate into the leak detection system exceeds the action leakage rate
for any sump, the owner or operator must:
1.
notify the Office of Environmental Services in writing of the exceedance within
seven days of the determination;
2.
submit a preliminary written assessment to the Office of Environmental
Services, 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 long-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
Office of Environmental Services the results of the analyses specified in LAC
33:V.2508.B.3-5, 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 must submit to the administrative
authority a report summarizing the results of any remedial actions taken and
remedial actions planned.
C. To make the leak and/or remediation
determinations in LAC 33:V.2508.B.3-5, the owner or operator must:
1. assess the sources of liquids and amounts
of liquids by source;
2. conduct a
fingerprint, hazardous constituent, or other analyses of the liquids in the
leak detection system to identify the sources of liquids and possible location
of any leaks, and the hazard and mobility of the liquid; and
3. assess the seriousness of any leaks in
terms of potential for escaping into the environment; or
4. document why such assessments are not
needed.
