Except as otherwise provided by Subsection
R315-264-1,
owners and operators of hazardous waste treatment, storage, or disposal
facilities that collect, store, or treat hazardous waste on drip pads shall
provide the following additional information:
(a) A list of hazardous wastes placed or to
be placed on each drip pad.
(b) If
an exemption is sought to Sections
R315-264-90
through 101, as provided by Subsection
R315-264-90,
detailed plans and an engineering report describing how the requirements of
Subsection
R315-264-90(b)(2)
shall be met.
(c) Detailed plans
and an engineering report describing how the drip pad is or will be designed,
constructed, operated and maintained to meet the requirements of Section
R315-264-573,
including the as-built drawings and specifications. This submission shall
address the following items as specified in Section
R315-264-571:
(1) The design characteristics of the drip
pad;
(2) The liner system;
(3) The leakage detection system,
including the leak detection system and how it is designed to detect the
failure of the drip pad or the presence of any releases of hazardous waste or
accumulated liquid at the earliest practicable time;
(4) Practices designed to maintain drip pads;
(5) The associated collection
system;
(6) Control of run-on to
the drip pad;
(7) Control of
run-off from the drip pad;
(8) The
interval at which drippage and other materials will be removed from the
associated collection system and a statement demonstrating that the interval
will be sufficient to prevent overflow onto the drip pad;
(9) Procedures for cleaning the drip pad at
least once every seven days to ensure the removal of any accumulated residues
of waste or other materials, including but not limited to rinsing, washing with
detergents or other appropriate solvents, or steam cleaning and provisions for
documenting the date, time, and cleaning procedure used each time the pad is
cleaned.
(10) Operating practices
and procedures that will be followed to ensure that tracking of hazardous waste
or waste constituents off the drip pad due to activities by personnel or
equipment is minimized;
(11)
Procedures for ensuring that, after removal from the treatment vessel, treated
wood from pressure and non-pressure processes is held on the drip pad until
drippage has ceased, including recordkeeping practices;
(12) Provisions for ensuring that collection
and holding units associated with the run-on and run-off control systems are
emptied or otherwise managed as soon as possible after storms to maintain
design capacity of the system;
(13)
If treatment is carried out on the drip pad, details of the process equipment
used, and the nature and quality of the residuals.
(14) A description of how each drip pad,
including appurtenances for control of run-on and run-off, will be inspected in
order to meet the requirements of Section
R315-264-573.
This information should be included in the inspection plan submitted under
Subsection
R315-270-14(b)(5).
(15) A certification signed by a qualified
Professional Engineer, stating that the drip pad design meets the requirements
of Subsection
R315-264-573(a)
through (f).
(16) A description of how hazardous waste
residues and contaminated materials will be removed from the drip pad at
closure, as required under Subsection
R315-264-575(a).
For any waste not to be removed from the drip pad upon closure, the owner or
operator shall submit detailed plans and an engineering report describing how
Subsections
R315-264-310(a) and
(b) will be complied with. This information
should be included in the closure plan and, where applicable, the post-closure
plan submitted under Subsection
R315-270-14(b)(13).
