Utah Admin. Code R315-265-301 - Landfills - 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 shall install two or more liners and a leachate collection and removal system above and between the liners, and operate the leachate collection and removal system, in accordance with Subsection R315-264-301(c), unless exempted under Subsection R315-264.301(d), R315-264-301(e), or R315-264-301(f).

(b) The owner or operator of each unit referred to in Subsection R315-265-301(a) shall notify the director at least 60 days before receiving waste. The owner or operator of each facility submitting notice shall file a part B application within six months of the receipt of the notice.

(c) The owner or operator of any replacement landfill unit is exempt from Subsection R315-265-301(a) if:

(1) the existing unit was constructed in compliance with the design standards of Sections 3004(o)(1)(A)(i) and 3004(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 R315-265-301(a) may be waived by the director for any monofill, if:

(1) the monofill contains only hazardous wastes from foundry furnace emission controls or metal casting molding sand, and the wastes do not contain constituents that would make the wastes hazardous for reasons other than the Toxicity Characteristic in Section R315-261-24, with EPA Hazardous Waste Numbers D004 through D017; and

(2)

(i)

(A) the monofill has at least one liner for which there is no evidence that the liner is leaking;

(B) the monofill is located more than one-quarter mile from an "underground source of drinking water", as that term is defined in Section R315-270-2; and

(C) the monofill is in compliance with generally applicable ground-water monitoring requirements for facilities with permits under RCRA Section 3005(c); or

(ii) 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 constituent into ground water or surface water at any future time.

(e) In the case of any unit that has a liner and leachate collection system that has been installed pursuant to the requirements of Subsection R315-265-301(a) and in good faith compliance with Subsection R315-265-301(a) and with guidance documents governing liners and leachate collection systems under Subsection R315-265-301(a), no liner or leachate collection system that is different from the liner or leachate collection system that was installed pursuant to Subsection R315-265-301(a) will be required for the unit by the director when issuing the first permit to the facility, except that the director will not be precluded from requiring installation of a new liner if the director has reason to believe that any liner installed pursuant to the requirements of Subsection R315-265-301(a) is leaking.

(f) The owner or operator shall 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 shall 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 such as tanks or basins associated with run-on and run-off control systems shall 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 that is subject to dispersal by wind shall cover or otherwise manage the landfill so that wind dispersal of the hazardous waste is controlled.

(j) As required by Section R315-265-13, the waste analysis plan shall include analyses needed to comply with Sections R315-265-312, R315-265-313, and R315-265-314. As required by Section R315-265-73, the owner or operator shall place the results of these analyses in the operating record of the facility.
