Waste Placement
Section 811
Section 811.321 Waste
Placement
a) Phasing of Operations
1) Waste disposal operations must move from the lowest portions
of the unit to the highest portions. Except as provided in subsection (a)(2),
the placement of waste must begin in the lowest part of the active face of the
unit, located in the part of the facility most downgradient, with respect to
groundwater flow.
2) The operator may dispose of wastes in areas other than those
specified in subsection (a)(1) only under any of the following conditions:
A) Climatic conditions, such as wind and precipitation, are such
that the placement of waste in the bottom of the unit would cause water
pollution, litter or damage to any part of the liner;
B) The topography of the land surrounding the unit makes the
procedure of subsection (a)(1) environmentally unsound, for example, because
steep slopes surround the unit; or
C) When groundwater monitoring wells, constructed in accordance
with the requirements of Section 811.319, are placed 50 feet, or less,
downgradient from the filled portions of the unit.
b) Initial Waste Placement
1) Construction, compaction and earth moving equipment must be
prohibited from operating directly on the leachate collection piping system
until a minimum of five feet of waste has been mounded over the system.
2) Construction, compaction and earth moving equipment must be
prohibited from operating directly on the leachate drainage blanket. Waste
disposal operations must begin at the edge of the drainage layer by carefully
pushing waste out over the drainage layer.
3) An initial layer of waste, a minimum of five feet thick, or,
alternatively, a temporary protective layer of other material suitable to
prevent the compacted earth liner from freezing, must be placed over the entire
drainage blanket prior to the onset of weather conditions that may cause the
compacted earth liner to freeze, except as provided in subsection (b)(4).
4) Waste must not be placed over areas that are subject to
freezing conditions until the liner has been certified or recertified by the
CQA officer designated pursuant to Section 811.502 and reconstructed (if
necessary) to meet the requirements of Section 811.306.
