Current through June, 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
					 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 § 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 §
					 264.573 of this chapter.
(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 post-closure plan submitted under §
					 270.14(b)(13).
