Current through Register Vol. 50, No. 9, September 20, 2024

Section V-4512 - Design and Operating Requirements

A. The owner or operator of each new landfill unit, each lateral expansion of a landfill unit, and each replacement of an existing landfill unit, must install two or more liners and a leachate collection and removal system above and between such liners and operate the leachate collection and removal systems, in accordance with LAC 33:V.2503.L, unless exempted by Subsection C, D, or E of this Section.

B. The owner or operator of each unit referred to in Subsection A of this Section must notify the Office of Environmental Services at least 60 days prior to receiving waste. The owner or operator of each facility submitting notice must file a Part II application within six months of the receipt of such notice.

C. The owner or operator of any replacement landfill unit is exempt from LAC 33:V.4512.A if:

1. the existing unit was constructed in compliance with the design standards of Section 3004(o)(1)(A)(i) and (o)(5) of the Resource Conservation and Recovery Act; and

2. there is no reason to believe that the liner is not functioning as designed.

D. The double liner requirement set forth in Subsection A of this Section may be waived by the administrative authority for any monofill, if it meets the requirements specified in Paragraphs D.1 and 2 of this Section.

1. The monofill contains only hazardous wastes from foundry furnace emission controls or metal casting molding sand, and such wastes do not contain constituents that would render the wastes hazardous for reasons other than the toxicity characteristics in LAC 33:V.4903.E, with EPA Hazardous Waste Numbers D004-D017.

2. The monofill meets the criteria of either LAC 33:V.4512.D.2.a or b below.

a. The monofill:

i. has at least one liner for which there is no evidence that such liner is leaking;

ii. is located more than 1/4 mile from an underground source of drinking water (as that term is defined in LAC 33:V.109); and

iii. is in compliance with generally applicable groundwater monitoring requirements for facilities with permits.

b. The owner or operator demonstrates that the monofill is located, designed, and operated so as to assure that there will be no migration of any hazardous waste or hazardous waste constituents into groundwater or surface water at any future time.

E. In the case of any unit in which the liner and leachate collection system have been installed pursuant to the requirements of LAC 33:V.4512.A and in good faith compliance with LAC 33:V.4512.A and with guidance documents governing liners and leachate collection systems under LAC 33:V.4512.A, no liner or leachate collection system which is different from that which was so installed pursuant to LAC 33:V.4512.A will be required for such unit by the administrative authority when issuing the first permit to such facility, except that the administrative authority will not be precluded from requiring installation of a new liner when the administrative authority has reason to believe that any liner installed pursuant to the requirements of LAC 33:V.4512.A is leaking.

F. The owner or operator must design, construct, operate, and maintain a run-on control system capable of preventing flow onto the active portion of the landfill during peak discharge from at least a 25-year storm.

G. The owner or operator must design, construct, operate, and maintain a run-off management system to collect and control at least the water volume resulting from a 24-hour, 25-year storm.

H. Collection and holding facilities (e.g., tanks or basins) associated with run-on and run-off control systems must be emptied or otherwise managed expeditiously after storms to maintain design capacity of the system.

I. The owner or operator of a landfill containing hazardous waste which is subject to dispersal by wind must cover or otherwise manage the landfill so that wind dispersal of the hazardous waste is controlled.
