A. In addition to complying with the requirements of Regulation .02 of this chapter, a person seeking a CHS facility permit to collect, store, or treat hazardous waste on a drip pad shall provide the Secretary with the following specific information in a permit application:

(1) A list of hazardous wastes placed or to be placed on each drip pad;

(2) If an exemption is sought to the requirements of COMAR 26.13.05.06 s -.06-7, as provided by COMAR 26.13.05.06 s A, the detailed plans and an engineering report describing how the requirements of COMAR 26.13.05.06 s A(3)(b) will be met; and

(3) Detailed plans and an engineering report that:

(a) Describe how the drip pad has been or will be designed, constructed, operated, and maintained to meet the requirements of COMAR 26.13.05.17 s -2;

(b) Include as-built drawings and specifications; and

(c) Include information specified in §B of this regulation.

B. The owner or operator shall ensure that the detailed plans and the engineering report required to be submitted by §A(3) of this regulation include the following items:

(1) Information on the:

(a) Design characteristics of the drip pad;

(b) Liner system;

(c) Leakage detection system, including how the system 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; and

(d) Associated collection system;

(2) A description of the practices that the owner or operator will use to maintain the drip pad;

(3) A description of how the owner or operator will control:

(a) Run-on to the drip pad; and

(b) Run-off from the drip pad;

(4) The interval at which the owner or operator will remove drippage and other materials from the associated collection system and a statement demonstrating that the interval will be sufficient to prevent overflow onto the drip pad;

(5) The procedures that the owner or operator will use to satisfy the cleaning requirements of COMAR 26.13.05.17 s -2F, including documentation requirements;

(6) The operating practices and procedures that the owner or operator will follow to minimize the tracking of hazardous waste or waste constituents off the drip pad due to activities by personnel or equipment;

(7) The procedures the owner or operator will follow to ensure that, after removal from the treatment vessel, treated wood from pressure and nonpressure processes is held on the drip pad until drippage has ceased, and the associated record-keeping practices;

(8) The provisions the owner or operator has made to ensure that, as soon as possible after a storm, each collection and holding unit associated with a run-on or run-off control system is emptied or otherwise managed to maintain the design capacity of the system;

(9) If treatment is carried out on the drip pad, the details of the process equipment used, and the nature and quality of the residuals;

(10) As part of the inspection plan required by Regulation .02D(19) of this chapter, a description of how the owner or operator will inspect each drip pad, including appurtenances for control of run-on and run-off, in order to meet the requirements of COMAR 27.13.05.17 s -2;

(11) A certification signed by an independent qualified registered professional engineer, stating that the drip pad design meets the requirements of COMAR 26.13.05.17 s -2A;

(12) A description of how hazardous waste residues and contaminated materials will be removed from the drip pad at closure, as required under COMAR 26.13.05.17 s -4A-D; and

(13) As part of the closure plan or the post-closure plan submitted under Regulation .02D(29) of this chapter, detailed plans and an engineering report describing how the requirements of COMAR 26.13.05.14 s J will be met for any waste that will not be removed from the drip pad at closure.
