Sec.  270.26  Special part B information requirements for drip pads.



    Except as otherwise provided by Sec.  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 Sec.  264.90 of this chapter, detailed plans and 

an engineering report

describing how the requirements of Sec.  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 Sec.  264.573 of this chapter, including the as-

built drawings and specifications. This submission must address the 

following items as specified in Sec.  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 Sec.  264.573 of this chapter. This information should 

be included in the inspection plan submitted under Sec.  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) Sec.  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 Sec.  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 Sec.  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 Sec.  270.14(b)(13).
