Current through June, 2024
Except as otherwise provided by section
					 11-264-1, owners and operators of
					 hazardous waste treatment, storage, or disposal facilities that collect, store,
					 or treat 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 subchapter F
				  of chapter
				  11-264, as provided by section
				  11-264-90, detailed plans and an engineering report describing how the
				  requirements of paragraph 11-264-90(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 section 11-264-573, including the
				  as-built drawings and specifications. This submission must address the
				  following items as specified in section 11-264-571:
(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 11-264-573. This information should
				  be included in the inspection plan submitted under paragraph 11-270-14(b)
				  (5).
(15) A certification signed by
				  an independent qualified, registered professional engineer, stating that the
				  drip pad design meets the requirements of subsections 11-264-573(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 11-264-575(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 subsections
				  11-264-310(a) and (b) will be complied with. This information should be
				  included in the closure plan and, where applicable, in the post-closure plan
				  submitted under paragraph 11-270-14(b)(13).
