Current through Register Vol. 50, No. 9, September 20, 2024
A. The
owner or operator of surface impoundment units subject to LAC 33:V.2903.J or K
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.2906.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 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
Office of Environmental Services the results of the analyses specified in
Paragraphs B.3-5 of this Section, the results of actions taken, and remedial
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 Office of Environmental Services a report summarizing the results
of any remedial actions taken and actions planned.
C. To make the leak and/or remediation
determinations in LAC 33:V.2906.B.3-5, the owner or operator must:
1. assess the sources of liquids and amounts
of liquids by source; and
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.
