Current through Register Vol. 51, page 10, July 15, 2024
The owner or operator of an existing municipal solid waste landfill
	 that meets the requirements of §
									74:36:07:105 shall submit a
	 collection and control system design plan prepared and approved by a
	 professional engineer. The collection and control system design plan
	 shall:
1. The design requirements in
  §§
									74:36:07:106 and §
									74:36:07:109;
2. Include any alternatives to the
  operational standards, test methods, procedures, compliance measures,
  monitoring, recordkeeping, or reporting provisions proposed by the owner or
  operator;
3. Conform to
  specifications for active collection systems in §
									74:36:07:108 or include a
  demonstration to the Secretary's satisfaction of the sufficiency of the
  alternative provisions;
4. Cover
  page that contains the engineer's seal to the Secretary within 1 year of the
  first nonmethane organic compound emission rate report in which the nonmethane
  organic compound emission rate equals or exceeds 34 megagrams per year, except
  as follows;
(a) If the owner or operator
  elects to recalculate the nonmethane organic compound emission rate after Tier
  2 nonmethane organic compound sampling and analysis and the resulting rate is
  less than 34 megagrams per year, annual periodic reporting must be resumed,
  using the Tier 2 determined site-specific nonmethane organic compound
  concentration, until the calculated nonmethane organic compound emission rate
  is equal to or greater than 34 megagrams per year or the landfill is closed.
  The revised nonmethane organic compound emission rate report, with the
  recalculated nonmethane organic compound emission rate based on nonmethane
  organic compound sampling and analysis, shall be submitted, following the
  procedures in §
										74:36:07:138, within 180 days of
  the first calculated exceedance of 34 megagrams per year;
(b) If the owner or operator elects to
  recalculate the nonmethane organic compound emission rate after determining a
  site-specific methane generation rate constant as provided in Tier 3, and the
  resulting nonmethane organic compound emission rate is less than 34 megagrams
  per year, annual periodic reporting shall be resumed. The resulting
  site-specific methane generation rate constant shall be used in the nonmethane
  organic compound emission rate calculation until such time as the emissions
  rate calculation results in an exceedance. The revised nonmethane organic
  compound emission rate report based on the provisions of §
										74:36:07:102 and the resulting
  site-specific methane generation rate constant shall be submitted to the
  Secretary within one year of the first calculated nonmethane organic compound
  emission rate equaling or exceeding 34 megagrams per year;
(c) If the owner or operator elects to
  demonstrate site-specific surface methane emissions are below 500 parts per
  million methane, the owner or operator shall submit annually a Tier 4 surface
  emissions report until a surface emissions readings of 500 parts per million
  methane or greater is found. If the Tier 4 surface emissions report shows no
  surface emissions readings of 500 parts per million methane or greater for four
  consecutive quarters at a closed landfill, then the owner or operator may
  reduce Tier 4 monitoring from a quarterly to an annual frequency. The Secretary
  may request additional information as may be necessary to verify the reported
  instantaneous surface emission readings. The Tier 4 surface emissions report
  shall clearly identify the location, date and time to the nearest second,
  average wind speeds including wind gusts, and reading, in parts per million, of
  any value 500 parts per million methane or greater, other than non-repeatable,
  momentary readings. For location, the owner or operator shall determine the
  latitude and longitude coordinates using an instrument with an accuracy of at
  least four meters. The coordinates shall be in decimal degrees with at least
  five decimal places. The Tier 4 surface emission report shall also include the
  results of the most recent Tier 1 and Tier 2 results in order to verify the
  landfill does not exceed 50 megagrams per year of nonmethane organic compounds.
  The annual Tier 4 surface emissions report shall be submitted as follows:
(i) The initial Tier 4 surface emissions
  report shall be submitted annually, starting within 30 days of completing the
  fourth quarter of Tier 4 surface emissions monitoring that demonstrates
  site-specific surface methane emissions are below 500 parts per million
  methane; and
(ii) The Tier 4
  surface emissions rate report shall be submitted within 1 year of the first
  measured surface exceedance of 500 parts per million methane;
(d) If the landfill is in the
  closed landfill subcategory, the owner or operator shall submit a collection
  and control system design plan to the Secretary within one year of the first
  nonmethane organic compound emission rate report in which the nonmethane
  organic compound emission rate equals or exceeds 50 megagrams per year, except
  as follows:
(i) If the owner or operator
  elects to recalculate the nonmethane organic compound emission rate after Tier
  2 nonmethane organic compound sampling and analysis and the resulting rate is
  less than 50 megagrams per year, annual periodic reporting shall be resumed,
  using the Tier 2 determined site-specific nonmethane organic compound
  concentration, until the calculated nonmethane organic compound emission rate
  is equal to or greater than 50 megagrams per year or the landfill is closed.
  The revised nonmethane organic compound emission rate report, with the
  recalculated nonmethane organic compound emission rate based on nonmethane
  organic compound sampling and analysis, shall be submitted within 180 days of
  the first calculated exceedance of 50 megagrams per year;
(ii) If the owner or operator elects to
  recalculate the nonmethane organic compound emission rate after determining a
  site-specific methane generation rate constant, as provided in Tier 3, and the
  resulting nonmethane organic compound emission rate is less than 50 megagrams
  per year, annual periodic reporting shall be resumed. The resulting
  site-specific methane generation rate constant shall be used in the nonmethane
  organic compound emission rate calculation until such time as the emissions
  rate calculation results in an exceedance. The revised nonmethane organic
  compound emission rate report and the resulting site-specific methane
  generation rate constant must be submitted to the Secretary within one year of
  the first calculated nonmethane organic compound emission rate equaling or
  exceeding 50 megagrams per year;
(iii) The owner or operator elects to
  demonstrate surface emissions are low, consistent with the provisions in
  subdivision (4)(c) of this section.
(iv) The landfill has already submitted a gas
  collection and control system design plan consistent with the provisions of 40
  C.F.R. Part 60, Subpart WWW (July 1, 2018); 40 C.F.R. Part 62, Subpart GGG
  (July 1, 2018); or §
											74:36:07:35;
(e) The owner or operator shall notify the
  Secretary that the design plan is completed and submit a copy of the plan's
  signature page. The Secretary has 90 days to decide whether the design plan
  should be submitted for review. If the Secretary chooses to review the plan,
  the approval process continues as described in subdivision (4)(f) of this
  section. However, if the Secretary indicates that submission is not required or
  does not respond within 90 days, the owner or operator can continue to
  implement the plan with the recognition that the owner or operator is
  proceeding at their own risk. In the event the design plan is required to be
  modified to obtain approval, the owner or operator shall take any steps
  necessary to conform any prior actions to the approved design plan and any
  failure to do so could result in an enforcement action;
(f) Upon receipt of an initial or revised
  design plan, the Secretary shall review the information submitted under
  subdivision (1) to (3), inclusive, of this section and approve it, disapprove
  it, or request additional information be submitted. Because of the many
  site-specific factors involved with landfill gas system design, alternative
  systems may be proposed. If the Secretary does not approve or disapprove the
  design plan, or does not request additional information be submitted within 90
  days of receipt, the owner or operator may continue with implementation of the
  design plan, recognizing they would be proceeding at their own risk;
  and
(g) If the owner or operator
  chooses to demonstrate compliance with the emission control requirements using
  a treatment system, the owner or operator must prepare a site-specific
  treatment system monitoring plan as specified in subdivision
  74:36:07:131(5)(a).
