                      Subpart B--Permit Application
 
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 an independent qualified, registered 
professional engineer, stating that the drip pad design meets the 
requirements of paragraphs (a) through (f) of 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).
