Oregon Administrative Rules › Chapter 340 - DEPARTMENT OF ENVIRONMENTAL QUALITY › Division 239 - LANDFILL GAS EMISSIONS › Section 340-239-0100 - Landfills with Greater Than or Equal to 200,000 Tons of Waste-in-Place

Current through Register Vol. 63, No. 7, July 1, 2024
(1) By October 1,
			 2022 the owner or operator of a landfill listed in Table 1 Part B or C of OAR
			 340-216-8010, having greater than 200,000 tons (181,000 metric tons) of
			 waste-in-place, must submit to DEQ an administratively complete permit
			 application, pursuant to OAR chapter 340, division 216, an initial
			 Waste-in-Place Report, pursuant to OAR 340-239-0700(3)(e), and a Methane
			 Generation Rate Report, pursuant to OAR 340-239-0700(3)(f).
(2) The owner or operator of an existing
			 landfill that does not yet have 200,000 tons of waste-in-place must, may not
			 accept solid waste in excess of 200,000 tons of waste-in-place without a permit
			 issued pursuant to OAR 340-216, and submission of an initial Waste-in Place
			 Report, pursuant to OAR 340-239-0700(3)(e)  and a Methane Generation Rate
			 Report, pursuant to OAR 340-239-0700(3)(f). Once the landfill reaches a size
			 greater than or equal to 200,000 tons of waste-in-place, the owner or operator
			 is subject to OAR 340-239-0100.
(3)
			 The owner or operator of a proposed new landfill that is designed to receive
			 greater than or equal to 200,000 tons of waste in the first year must submit an
			 administratively complete permit application, pursuant to OAR chapter 340,
			 division 216, prior to receiving any waste. The owner or operator of a new
			 landfill also must submit to DEQ, no later than January 30 after the first
			 calendar year in which the landfill initially accepted waste, an initial
			 Waste-in-Place Report, pursuant to OAR 340-239-0700(3)(e), and a Methane
			 Generation Rate Report, pursuant to OAR 340-239-0700(3)(f).
(4) The owner or operator of a landfill
			 having greater than or equal to 200,000 tons of waste-in-place must submit an
			 annual Waste-in-Place Report to DEQ pursuant to OAR 340-239-0700(3)(e)  and an
			 annual Methane Generation Rate Report, pursuant to OAR 340-239-0700(3)(f),
			 until the owner or operator submits a Closure Notification pursuant to OAR
			 340-239-0700(3)(a). The initial Waste-in-Place Report and Methane Generation
			 Rate Report submitted by a landfill pursuant to sections (1), (2) or (3) shall
			 satisfy this requirement for the initial year it applies to a
			 landfill.
(5) If the calculated
			 methane generation rate reported by the owner or operator of a landfill
			 according to section (1), (2) (3), or (4) of this rule is less than 664 metric
			 tons (732 tons) per year, the owner or operator must:
(a) If the landfill is active:
(A) Recalculate the methane generation rate
			 annually using the procedures specified in OAR 340-239-0800(2);
(B) Submit an annual Methane Generation Rate
			 Report to DEQ pursuant to OAR 340-239-0700(3)(f)  until either of the following
			 conditions is met:
(i) The calculated methane
			 generation rate is greater than or equal to 664 metric tons (732 tons) per
			 year, or
(ii) The owner or operator
			 submits a Closure Notification pursuant to OAR 340-239-0700(3)(a).
(C) Maintain the cover in any
			 areas of the landfill not exempt per OAR 340-239-0300  so as to minimize
			 landfill gas emissions and visually inspect the landfill surface annually for
			 signs of methane releases including distressed vegetation, cracks or
			 seeps.
