Current through Register Vol. 50, No. 6, June 20, 2024

Section V-525 - Specific Part II Information Requirements for Surface Impoundments

Except as otherwise provided in LAC 33:V.1501, owners and operators of facilities that treat, store, or dispose of hazardous waste in surface impoundments must provide the following additional information:

A. a list of the hazardous wastes placed or to be placed in each surface impoundment;

B. detailed plans and an engineering report describing how the surface impoundment is designed and is or will be constructed, operated and maintained to meet the requirements of LAC 33:V.1504, 2903, 2904, and 2906. This submission must address the following items:

1. the liner system (except for an existing portion of a surface impoundment). If an exemption from the requirement for a liner is sought as provided by LAC 33:V.2903.B, submit 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 groundwater or surface water at any future time;

2. the double liner and leak (leachate) detection, collection and removal system, if the surface impoundment must meet the requirements of LAC 33:V.2903.J. If an exemption from the requirements for double liners and leak detection, collection and removal system or alternative design is sought as provided by LAC 33:V.2903.C, K, or L, submit appropriate information;

3. 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;

4. the construction quality assurance (CQA) plan, if required under LAC 33:V.1504;

5. proposed action leakage rate, with rationale, if required under LAC 33:V.2904 and response action plan, if required under LAC 33:V.2906;

6. prevention of overtopping; and

7. structural integrity of dikes;

C. a description of how each surface impoundment, including the double liner system, leak detection system, cover system, and appurtenances for control of overtopping, will be inspected in order to meet the requirements of LAC 33:V.2907.B, C, and E. This information must be included in the inspection plan submitted under LAC 33:V.517.G;

D. a description of how each surface impoundment, including the liner and cover systems and appurtenances for control of overtopping, will be inspected in order to meet the requirements of LAC 33:V.2907.B and C;

E. a certification by a qualified engineer which attests to the structure integrity of each dike, as required under LAC 33:V.2907.D. For new units, the owner or operator must submit a statement by a qualified engineer that he will provide such a certification upon completion of construction in accordance with the plans and specifications;

F. a description of the procedure to be used for removing a surface impoundment from service, as required under LAC 33:V.2909.B and C;

G. a description of how hazardous waste residues and contaminated materials will be removed from the unit at closure, as required under LAC 33:V.2911.A. For any wastes not to be removed from the unit upon closure, the owner or operator must submit detailed plans and an engineering report describing how LAC 33:V.2911.B and C will be complied with. This information should be included in the closure plan and, where applicable, the post-closure plan;

H. if ignitable or reactive wastes are to be placed in a surface impoundment an explanation of how LAC 33:V.2913 will be complied with;

I. if incompatible wastes, or incompatible wastes and materials will be placed in a surface impoundment, an explanation of how LAC 33:V.2915 will be complied with;

J. a waste management plan for EPA Hazardous Waste Numbers F020, F021, F022, F023, F026 and F027 describing how the surface impoundment is or will be designed, constructed, operated, and maintained to meet the requirements of LAC 33:V.2917. This submission must address the following items:

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 codisposed with these wastes; and

4. the effectiveness of additional treatment, design, or monitoring techniques; and

K. information on air emission control equipment as required in LAC 33:V.526.
