If leachate or run-off from a pile is a hazardous waste, then control of the leachate or run-off must be accomplished by either of the following means:
a) Control by Pile Design, Construction, and Operation
1) The
pile must be placed on an impermeable base that is compatible with the waste
under the conditions of treatment or storage;
2) The owner or operator must design,
construct, operate and maintain a run-on control system capable of preventing
flow onto the active portion of the pile during peak discharge from at least a
25-year storm;
3) The owner or
operator must design, construct, operate and maintain a run-off management
system to collect and control at least the water volume resulting from a
24-hour, 25-year storm; and
4)
Collection and holding facilities (e.g., tanks or basins) associated with
run-on and run-off control systems must be emptied or otherwise managed
expeditiously to maintain design capacity of the system; or
b) Alternative Control
1) The pile must be protected from
precipitation and run-on by some other means; and
2) No liquids or wastes containing free
liquids may be placed in the pile.
BOARD NOTE: If collected leachate or run-off is discharged through a point source to waters of the United States, it is subject to the requirements of Section 12 of the Act.
