Current through Register Vol. 48, No. 5, May 24, 2024

Section 61-79.265.N.301 - 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 system, in accordance with 264.301(c), unless exempted under 264.301(d), (e), or (f) of this chapter.

(b) The owner or operator of each unit referred to in paragraph (a) of this section must notify the Department at least sixty days prior to receiving waste. The owner or operator of each facility submitting notice must file a Part B application within six months of the receipt of such notice.

(c) The owner or operator of any replacement landfill unit is exempt from paragraph (a) of this section if:

(1) The existing unit was constructed in compliance with the design standards of section3004(o)(1)(A)(i) and (o)(5)(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 paragraph (a) of this section may be waived by the Department for any monofill, if:

(1) The monofill contains only hazardous wastes from foundry furnace emission controls or metal casting molding sand, and such wastes do not contain constituents which would render the wastes hazardous for reasons other than the Toxicity Characteristic in R.61-79.261.24 of this chapter, 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 such 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 Department regulation R.61-68); and

(C) The monofill is in compliance with generally applicable groundwater monitoring requirements for facilities with permits under R.61-79.270 and 44-56-60 or RCRA section3005(c)(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 groundwater or surface water at any future time.

(e) In the case of any unit in which the liner and leachate collection system has been installed pursuant to the requirements of paragraph (a) of this section and in good faith compliance with paragraph (a) of this section and with guidance documents governing liners and leachate collection systems under paragraph (a) of this section, no liner or leachate collection system which is different from that which was so installed pursuant to paragraph (a) of this section will be required for such unit by the Department when issuing the first permit to such facility, except that the Department will not be precluded from requiring installation of a new liner when the Department has reason to believe that any liner installed pursuant to the requirements of paragraph (a) of this section is leaking. (revised 12/92)

(f) The owner or operator must design, construct, operate, and maintain a runon 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 runoff 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 runon and runoff 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.

(j) The owner or operator of a landfill which is not exempt from the requirements of R.61-79.265 Subpart F pursuant to R.61-79.265.90(c)(c)shall maintain at least ten feet of naturally occurring material with an average permeability of no more than 1 E-06 centimeter per second directly beneath and in contact with the bottom of the constructed liner system as required under R.61-79.265.301(a)(a).

[Comment: As required by 265.13, the waste analysis plan must include analyses needed to comply with 265.312, 265.313, and 265.314. As required by 265.73, the owner or operator must place the results of these analyses in the operating record of the facility.] (revised 12/92; moved 12/93; moved 5/96)
