				  profile;
(2) Detailed drawings of
				  the structure which is or will be provided to immediately stop flow into the
				  impoundment to comply with COMAR

(6) Liner installation instructions to comply
				  with the requirements of COMAR
				  26.13.05.11F(1),
				  and for existing facilities if owner or operator proposes to rely on existing
				  liners, a description of the installation procedures used;
(7) Design details of the leachate removal
				  system, the basis of design, and a description of the operating procedures to
				  be used to ensure free flow from the collection system in accordance with COMAR
				  26.13.05.11C(4);
(8) Design plans and specifications and basis
				  of design of any structures needed to comply with COMAR
				  26.13.05.11C(5);
(9) A description of the maintenance and
				  repair procedures proposed to comply with COMAR
				  26.13.05.11C(4)

(10) A description of the operating
				  procedures that will ensure compliance with COMAR
				  26.13.05.11I and

(11) A certification by a
				  qualified engineer which complies with COMAR
				  26.13.05.11F(3)
				  or, for a new facility, a statement by a qualified engineer that the engineer
				  will provide this certification upon completion of construction in accordance
				  with the plans and specifications;
(12) A description of the procedure to be
				  used for removing a surface impoundment from service, as required under COMAR
				  26.13.05.11H(2) and
				  (3), as part of the contingency plan
				  submitted under Regulation .02D(21) of this chapter;
(13) As part of the closure plan, and, if
				  applicable, the post-closure plan submitted under Regulation .02D(29) of this
				  chapter:
(a) A description of how hazardous
				  waste residues and contaminated materials will be removed from the unit at
				  closure, as required under COMAR
				  26.13.05.11G(1)(a);
				  and
(b) For any wastes not to be
				  removed from the unit upon closure, detailed plans and an engineering report
				  describing how COMAR
				  26.13.05.11G(1)(b)-(d) and
				  (2) will be complied
				  with;
(14) If ignitable
				  or reactive wastes are to be placed in a surface impoundment, an explanation of
				  how COMAR 26.13.05.11I will
				  be complied with;
(15) If
				  incompatible wastes and materials will be placed in a surface impoundment, an
				  explanation of how COMAR
				  26.13.05.11J will
				  be complied with;

				  description of the liner system or, if an exemption from the requirement for a
				  liner is sought as provided by COMAR
				  26.13.05.11B(6),
				  detailed plans and engineering and hydrogeologic reports, as appropriate,
				  describing alternate design and operating practices that will, in conjunction
				  with location aspects, prevent the migration of any hazardous constituents into
				  the ground water or surface water at any future time;
