Section 1302-122-B-122.18 - Specific Part B requirements for waste piles

Except as otherwise provided in Section 264.250, owners and operators of facilities that store or treat hazardous waste in waste piles must provide the following additional information:

(a) A list of hazardous wastes placed or to be placed in each waste pile;

(b) If an exemption is sought to Section 264.251 and Subpart F of Part 264 as provided by Section 264.250 (c) or Section 264.90 (b)(2), an explanation of how the standards of Section 264.250 (c) will be complied with or detailed plans and an engineering report describing how the requirements of Section 264.90(b)(2) will be met;

(c) Detailed plans and an engineering report describing how the waste pile is designed and is or will be constructed, operated and maintained to meet the requirements of Section Section 264.19, 264.251, 264.252, and 264.53 of these regulations, addressing the following items:

(1)

(i) The liner system (except for an existing portion of a waste pile), if the waste pile must meet the requirements of Section 264.251 (a) of these regulations. If an exemption from the requirement for a liner is sought as provided by Section 264.251 (b) of these regulations, submit detailed plans, and engineering and hydrogeological reports, as appropriate, describing alternate designs 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;

(ii) The double liner and leak (leachate) detection, collection, and removal system, if the waste pile must meet the requirements of Section 264.251 (c) of these regulations. If an exemption from the requirements for double liners and a leak detection, collection, and removal system or alternative design is sought as provided by Section 264.251 (d), (e), or (f) of these regulations, submit appropriate information;

(iii) If the leak detection system is located in a saturated zone, submit detailed plans and an engineering report explaining the leak detection system design and operation, and the location of the saturated zone in relation to the leak detection system;

(iv) The construction quality assurance (CQA) plan if required under Section 264.19 of these regulations;

(v) Proposed action leakage rate, with rationale, if required under Section 264.252 of these regulations, and response action plan, if required under Section 264.253 of these regulations;

(1) Control of run-on;

(2) Control of run-off;

(3) Management of collection and holding units associated with run-on and run-off control systems; and

(4) Control of wind dispersal of particulate matter, where applicable.

(d) A description of how each waste pile, including the double liner system, leachate collection and removal system, leak detection system, cover system, and appurtenances for control of run-on and run-off, will be inspected in order to meet the requirements of Section 264.254 (a), (b) and (c) of these regulations. This information must be included in the inspection plan submitted under Section 122.14 (b)(5);

(e) If treatment is carried out on or in the pile, details of the process and equipment used, and the nature and quality of the residuals;

(f) If ignitable or reactive wastes are to be placed in a waste pile, an explanation of how the requirements of Section 264.256 will be complied with;

(g) If incompatible wastes, or incompatible wastes and materials will be placed in a waste pile, an explanation of how Section 264.257 will be complied with;

(h) A description of how hazardous waste residues and contaminated materials will be removed from the waste pile at closure, as required under Section 264.258 (a). For any waste not to be removed from the waste pile upon closure, the owner or operator must submit detailed plans and an engineering report describing how 264.310(a) and (b) will be complied with. This information should be included in the closure plan and, where applicable, the post-closure plan submitted under Section 122.14(b)(13);

(i) A waste management plan for EPA Hazardous Wastes Nos. F020, F021, F022, F023, F026, and F027 describing how a waste pile that is not enclosed (as defined in Section 264.250(c)) is or will be designed, constructed, operated, and maintained to meet the requirements of Section 264.259. This submission must address the following items as specified in Section 264.259:

(1) The volume, physical, and chemical characteristics of the wastes to be disposed in the waste pile, including their potential to migrate through soil or to volatilize or escape into the atmosphere;

(2) The attenuative properties of underlying and surrounding soils or other materials;

(3) The mobilizing properties of other materials co-disposed with these wastes; and

(4) The effectiveness of additional treatment, design, or monitoring techniques.
