Current through Register Vol. 48, No. 38, September 20, 2024
Except as otherwise provided by 35 Ill. Adm. Code
724.101,
the owner or operator of a hazardous waste treatment, storage, or disposal
facility that collects, stores, or treats hazardous waste on drip pads must
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 Subpart F of 35 Ill. Adm. Code 724, as provided by 35
Ill. Adm. Code
724.190,
detailed plans and an engineering report describing how the requirements of 35
Ill. Adm. Code
724.190(b)(2)
will 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 35 Ill. Adm. Code
724.673,
including the as-built drawings and specifications. This submission must
address the following items, as specified in 35 Ill. Adm. Code
724.671:
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) Cleaning procedures and documentation:
A) 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
B) 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 35 Ill. Adm. Code 724.673. This information
must be included in the inspection plan submitted under Section
703.183(e);
15) A certification signed by a qualified
Professional Engineer, stating that the drip pad design meets the requirements
of 35 Ill. Adm. Code
724.673(a)
through (f); and
16) A description of how hazardous waste
residues and contaminated materials will be removed from the drip pad at
closure, as required under 35 Ill. Adm. Code
724.675(a).
For any waste not to be removed from the drip pad upon closure, the owner or
operator must submit detailed plans and an engineering report describing how 35
Ill. Adm. Code
724.410(a) and
(b) will be complied with. This information
must be included in the closure plan and, where applicable, the post-closure
plan submitted under Section
703.183(m).
