Section 1302-122-B-122.21 - Specific Part B information requirements for landfills

Except as otherwise provided in Section 264.300, owners and operators of facilities that dispose of hazardous waste in landfills must provide the following additional information:

(a) A list of the hazardous wastes placed or to be placed in each landfill or landfill cell;

(b) Detailed plans and an engineering report describing how the landfill is designed and is or will be constructed, operated and maintained to meet the requirements of Section Section 264.19, 264.301, 264.302, and 264.303 of these regulations, addressing the following items:

(1)

(i) The liner system (except for an existing portion of a landfill), if the landfill must meet the requirements of Section 264.301 (a) of these regulations. If an exemption from the requirement for a liner is sought as provided by Section 264.301 (b) of these regulations, submit detailed plans, and engineering and hydrogeologic 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 landfill must meet the requirements of Section 264.301 (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 264.301 (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 264.302 of these regulations, and response action plan, if required under Section 264.303 of these regulations.

(2) Control of run-on;

(3) Control of run-off;

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

(5) Control of wind dispersal of particulate matter, where applicable;

(c) A description of how each landfill, 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 264.303(a), (b), and (c) of these regulations. This information must be included in the inspection plan submitted under Section 122.14 (b)(5);

(d) Detailed plans and an engineering report describing the final cover which will be applied to each landfill or landfill cell at closure in accordance with Section 264.310 (a), and a description of how each landfill will be maintained and monitored after closure in accordance with Section 264.310 (b). This information should be included in the closure and post-closure plans submitted under Section 122.14 (b)(13);

(e) If ignitable or reactive wastes will be landfilled, an explanation of how Section 264.312 will be complied with;

(f) If incompatible wastes, or incompatible wastes and materials will be landfilled, an explanation of how Section 264.313 will be complied with;

(g) If bulk or non-containerized liquid waste or wastes containing free liquids is to be landfilled prior to May 8, 1985, an explanation of how the requirements of Section 264.314 (a) will be complied with;

(h) If containers of hazardous waste are to be landfilled, an explanation of how the requirements of Section 264.315 or Section 264.326, as applicable, will be complied with;

(i) A waste management plan for EPA Hazardous Wastes Nos. F020, F021, F022, F023, F026, and F027 describing how a landfill is or will be designed, constructed, operated, and maintained to meet the requirements of Section 264.317. This submission must address the following items as specified in Section 264.317:

(1) The volume, physical, and chemical characteristics of the wastes, 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.

(Amended November 21, 1985; May 8, 1986; August 29, 1988; August 10, 1990, August 1, 1995, August 21, 1997, January 1, 1999)
