Current through June 24, 2024
Except as otherwise provided by s.
					 NR
					 664.0001, owners and operators of hazardous waste
					 treatment, storage or disposal facilities that collect, store or treat
					 hazardous waste on drip pads shall provide all of the following additional
					 information:
(1) A list of hazardous
				  wastes placed or to be placed on each drip pad.
(2) If an exemption is sought to subch. F of
				  ch. NR 664, as provided by s.
				  NR
				  664.0090, detailed plans and an engineering report
				  describing how s.
				  NR
				  664.0090(2) (b) will be
				  met.
(3) Detailed plans and an
				  engineering report describing how the drip pad is or will be designed,
				  constructed, operated and maintained to meet s.
				  NR
				  664.0573, including the as-built drawings and
				  specifications. This submission shall address all of the following items as
				  specified in s.
				  NR
				  664.0571:
(a) The
				  design characteristics of the drip pad.
(b) The liner system.
(c) 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.
(d) Practices designed to maintain drip
				  pads.
(e) The associated collection
				  system.
(f) Control of run-on to
				  the drip pad.
(g) Control of
				  run-off from the drip pad.
(h) 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.
(i) Procedures for cleaning the drip pad at
				  least once every 7 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.
(j) 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.
(k)
				  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.
(l) 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.
(m)
				  If treatment is carried out on the drip pad, details of the process equipment
				  used, and the nature and quality of the residuals.
(n) A description of how each drip pad,
				  including appurtenances for control of run-on and run-off, will be inspected in
				  order to meet s.
				  NR
				  664.0573. This information shall be included in the
				  inspection plan submitted under s.
				  NR
				  670.014(2) (e).
(o) A certification signed by a qualified
				  professional engineer, stating that the drip pad design meets s.
				  NR 664.0573(1)
				  to (6).
(p) A description of how hazardous waste
				  residues and contaminated materials will be removed from the drip pad at
				  closure, as required under s.
				  NR
				  664.0575(1). 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 s.
				  NR 664.0310(1) and
				  (2) will be complied with. This information
				  shall be included in the closure plan and, where applicable, the long-term care
				  plan submitted under s.
				  NR
				  670.014(2) (m).
