Current through Register Vol. 48, No. 6, June 28, 2024
Except as otherwise provided by 264.1 of this chapter,
					 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 subpart F of part 264 of this chapter, as provided by
				  264.90 of this chapter, detailed plans and an engineering report describing how
				  the requirements of 264.90(b)(2) of this chapter 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 264.573 of this chapter, including the
				  as-built drawings and specifications. This submission must address the
				  following items as specified in 264.571 of this chapter:
(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 runoff
				  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 nonpressure 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 runoff 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 runoff, will be inspected in
				  order to meet the requirements of 264.573 of this chapter. This information
				  should be included in the inspection plan submitted under 270.14(b)(5) of this
				  part.
(15) A certification signed
				  by a qualified Professional Engineer, stating that the drip pad design meets
				  the requirements of paragraphs (a) through (f) of section 264.573.
(16) A description of how hazardous waste
				  residues and contaminated materials will be removed from the drip pad at
				  closure, as required under 264.575(a) of this chapter. 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 264.310 (a) and (b) of
				  this chapter will be complied with. This information should be included in the
				  closure plan and, where applicable, the postclosure plan submitted under
				  270.14(b)(13).
