Current through all regulations passed and filed through September 16, 2024
(A) The owner or operator of landfill units
subject to paragraph (C) or (D) of rule
3745-57-03
of the Administrative Code 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 paragraph (B) of this rule.
(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 director in
writing of the exceedance within seven days
after the
determination;
(2) Submit a
preliminary written assessment to the director within fourteen 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 thirty days after the
notification that the action leakage rate has been exceeded, submit to the
director the results of the analyses specified in paragraphs (B)(3), (B)(4),
and (B)(5) of this rule, 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
director a report summarizing the results of any remedial actions taken and
actions planned.
(C) To
make the leak and/or remediation determinations in paragraphs (B)(3), (B)(4),
and (B)(5) of this rule, the owner or operator must:
(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 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.
