Current through Register Vol. 48, No. 28, July 12, 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).
