Section 3745-535-650 - Surface water and leachate management
Universal Citation: OH Admin Code 3745-535-650
Current through all regulations passed and filed through March 18, 2024
(A) Surface water management. The owner or operator shall manage surface water at a minimum as follows:
(1)
Employ surface
water control structures designed and constructed in accordance with rule
3745-27-08 of the Administrative
Code such that the following are achieved:
(a)
Run-on and runoff
of surface water are controlled.
(b)
Erosion is
minimized.
(c)
Infiltration of water through the cover material and
cap system is minimized.
(2)
Maintain surface
water control structures and ensure surface water is managed in accordance with
the following:
(a)
Diverted from areas where solid waste is being or has
been deposited.
(b)
If ponding or erosion occurs on areas of the facility
where waste is being or has been deposited, complete actions as necessary to
correct the conditions causing the ponding or erosion.
(B) Leachate management. The owner or operator shall manage leachate as follows:
(1)
Except as specified in paragraphs (B)(2) and (B)(3) of
this rule, excluding leachate sumps, ensure the depth of leachate on the liner
is not more than one foot.
(2)
For a phase that
drains to a sump where select waste is currently being placed, if the depth of
leachate on the liner, excluding leachate sumps, exceeds one foot as a result
of a precipitation event that generates 0.1 inches or more of rainfall in
twenty-four hours as measured by an onsite rain gauge, ensure the depth of
leachate no longer exceeds one foot not later than seven days after the most
recent precipitation event that generates 0.1 inches or more of rainfall and
record the date of such occurrence and corrective action in the daily log of
operations.
(3)
Maintain the integrity of the engineered components of
the leachate collection system, including but not limited to pumps, and repair
any damage to or failure of the components. Upon discovery of a malfunctioning
component that results in the depth of leachate exceeding one foot on the
liner, the owner or operator shall do the following:
(a)
Record the
location and component malfunctioning in the daily log.
(b)
Notify the
appropriate Ohio EPA district office and the approved health district in
writing not later than twenty-four hours after discovery of the malfunctioning
component and exceedance of one foot of depth if the engineered component is
still malfunctioning.
(c)
Ensure the depth of leachate no longer exceeds one foot
not later than seven days after discovery of the malfunction.
(4)
If a
leachate outbreak occurs at the facility, repair the outbreak and do the
following:
(a)
Contain and properly manage the leachate at the
facility.
(b)
Collect and dispose of the leachate as necessary in
accordance with paragraphs (B)(6) and (B)(9) of this rule.
(c)
Take action to
minimize, control, or eliminate the conditions that contribute to the
production of leachate.
(5)
Visually or
physically inspect the newly constructed segments of the leachate management
system that are accessible not later than sixty days after placement of the
initial lift of waste to ensure that crushing has not occurred and inspect the
accessible segments annually thereafter to ensure that clogging has not
occurred.
(6)
Treat and dispose of collected leachate in accordance
with Chapter 6111. of the Revised Code and one of the following methods:
(a)
On site at the
facility.
(b)
By pretreating collected leachate on-site and disposing
of the treated leachate off-site of the facility.
(c)
Off-site of the
facility.
(7)
If leakage into the leak detection system of a leachate
pond exceeds the action leakage rate established in the approved permit to
install or five hundred gallons per acre per day, whichever is less, repair the
leachate pond containment system such that the leakage is reduced to less than
the established action leakage rate or five hundred gallons per acre per day,
whichever is less.
(8)
Prepare a contingency plan for the storage and disposal
of leachate that describes the immediate and long term steps, including the
setting aside of land for the construction and operation of an on-site
treatment facility, to be taken for leachate management in the event that
collected leachate cannot be managed in accordance with the management option
selected in paragraph (B)(6) of this rule.
(9)
In the event that
collected leachate cannot be managed in accordance with the management option
selected in paragraph (B)(6) of this rule, implement the contingency plan for
the storage and disposal of leachate.
(C) The owner or operator shall place in the operating record copies of the following:
(1)
The design of the
surface water control structures specified in paragraph (A) of this
rule.
(2)
The contingency plan for the storage and disposal of
leachate in accordance with paragraph (B)(8) of this rule.
(D) If a substantial threat to surface water exists, the director or approved health district may require the owner or operator to monitor the surface water.
