Haw. Code R. § 11-264-273 - Design and operating requirements
The director will 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) 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 11-264-272. At a minimum, the director
will specify the following in the facility permit:
(1) The rate and method of waste application
to the treatment zone;
(2) Measures
to control soil pH;
(3) Measures to
enhance microbial or chemical reactions (e.g., fertilization, tilling);
and
(4) Measures to control the
moisture content of the treatment zone.
(b) 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) 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 twenty-five year storm.
(d) 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 twenty-four hour, twenty-five year storm.
(e) 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) If the
treatment zone contains particulate matter which may be subject to wind
dispersal, the owner or operator must manage the unit to control wind
dispersal.
(g) The owner or
operator must inspect the unit weekly and after storms to detect evidence of:
(1) Deterioration, malfunctions, or improper
operation of run-on and run-off control systems; and
(2) Improper functioning of wind dispersal
control measures.
