Design and Operating Requirements
Section 724
Section 724.373Â Design and
Operating Requirements
The Agency must specify in the
facility permit how the owner or operator will design, construct, operate, and
maintain the land treatment unit in compliance with this Section.
a)Â Â Â Â Â Â Â Â The owner or operator must design, construct, operate, and
maintain the unit to maximize the degradation, transformation, and
immobilization of hazardous constituents in the treatment zone. The owner or
operator must design, construct, operate, and maintain the unit in accord with
all design and operating conditions that were used in the treatment
demonstration under Section 724.372. At a minimum, the Agency must specify the
following in the facility permit:
1)Â Â Â Â Â Â Â Â The rate and method of waste application to the treatment
zone;
2)Â Â Â Â Â Â Â Â Measures to control soil pH;
3)Â Â Â Â Â Â Â Â Measures to enhance microbial or chemical reactions (e.g.,
fertilization, tilling, etc.); and
4)Â Â Â Â Â Â Â Â Measures to control the moisture content of the treatment
zone.
b)Â Â Â Â Â Â Â Â The owner or operator must design, construct, operate, and
maintain the treatment zone to minimize run-off of hazardous constituents
during the active life of the land treatment unit.
c)Â Â Â Â Â Â Â Â The owner or operator must design, construct, operate, and
maintain a run-on control system capable of preventing flow onto the treatment
zone during peak discharge from at least a 25-year storm.
d)Â Â Â Â Â Â Â Â 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.
e)Â Â Â Â Â Â Â Â 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 after storms to maintain the design capacity of the
system.
f)Â Â Â Â Â Â Â Â If the treatment zone contains particulate matter that may be
subject to wind dispersal, the owner or operator must manage the unit to
control wind dispersal.
g)Â Â Â Â Â Â Â Â The owner or operator must inspect the unit weekly and after
storms to detect evidence of the following:
1)Â Â Â Â Â Â Â Â Deterioration, malfunctions, or improper operation of run-on
and run-off control systems; and
2)Â Â Â Â Â Â Â Â Improper functioning of wind dispersal control measures.
