II.B.2.a.1 Monitoring:

(a) NMOC emission rate. The permittee shall calculate the NMOC emission rate using either
the equation provided in paragraph (a)(1) or (a)(2) below. Both equations may be used if the
actual year to year solid waste acceptance rate is known, as specified in paragraph (a)(1) for

unknown, as specified in paragraph (a)(2), for part of the life of the landfill. The values to be
used in both equations are 0.02 per year for "k", 170 cubic meters per megagram for Lo, and
4,000 parts per million by volume as hexane for the CNMOC [40 CFR 60.764(a)(1)].

(1) The following equation shall be used if the actual year to year solid waste acceptance rate
is known.

MNMOC= Sum (2 k Lo Mi(e-kti)(CNMOC)(3.6x10-9)) of i through n where,

MNMOC=Total NMOC emission rate from the landfill, megagrams per year
k = methane generation rate constant, year-1

Lo = methane generation potential, cubic meters per megagram solid waste

Mi = mass of solid waste in the ith section, megagrams

ti = age of the ith section, years

CNMOC = concentration of NMOC, parts per million by volume as hexane

3.6x10-9 = conversion factor

The mass of nondegradable solid waste may be subtracted from the total mass of solid
waste in a particular section of the landfill when calculating the value for Mi if
documentation of the nature and amount of such wastes is maintained.

[40 CFR 60.764(a)(1)(i)(A)-(B)]
16

(2) The following equation shall be used if the actual year-to-year solid waste acceptance
rate is unknown.

MNMOC = 2Lo R (e-kc-e-kt) CNMOC (3.6 x 10-9)

Where:

MNMOC = mass emission rate of NMOC, megagrams per year

Lo = methane generation potential, cubic meters per megagram solid waste

R = average annual acceptance rate, megagrams per year

k = methane generation rate constant, year-1

t = age of landfill, years

CNMOC = concentration of NMOC, parts per million by volume as hexane

c = time since closure, years; for active landfill c = O and e-kc = 1

3.6 x 10-9 = conversion factor.

The mass of nondegradable solid waste may be subtracted from the total mass of solid
waste in a particular section of the landfill when calculating the value of R, if
documentation of the nature and amount of such wastes is maintained.

this subpart, the permittee shall calculate the NMOC emission rate for purposes of determining
when the system can be capped, removed or decommissioned as provided in 40 CFR
60.762(b)(2)(v), using Equation 3 below:

MNMOC = 1.89 x 10-3QLFG CNMOC (Eq. 3)

Where:

MNMOC = Mass emission rate of NMOC, megagrams per year.

QLFG = Flow rate of landfill gas, cubic meters per minute.

CNMOC = NMOC concentration, parts per million by volume as hexane.
20

(1) The flow rate of landfill gas, QLFG, shall be determined by measuring the total landfill gas
flow rate at the common header pipe that leads to the control system using a gas flow
measuring device calibrated according to the provisions of section 10 of Method 2E of
appendix A of 40 CFR Part 60.

(2) The average NMOC concentration, CNMOC, shall be determined by collecting and
analyzing landfill gas sampled from the common header pipe before the gas moving or
condensate removal equipment using the procedures in Method 25 or Method 25C. The
sample location on the common header pipe shall be before any condensate removal or other
gas refining units. The landfill permittee shall divide the NMOC concentration from Method
25 or Method 25C of appendix A of 40 CFR Part 60 by six to convert from CNMOC as
carbon to CNMOC as hexane.

(3) The permittee may use another method to determine landfill gas flow rate and NMOC
concentration if the method has been approved by the Administrator.

(i) Within 60 days after the date of completing each performance test (as defined in 40
CFR 60.8), the permittee shall submit the results of the performance test, including any
associated fuel analyses, according to 40 CFR 60.767(i)(1).

permittee shall estimate the NMOC emission rate for comparison to the Prevention of Significant
Deterioration major source and significance levels in 40 CFR 51.166 or 52.21 using Compilation
of Air Pollutant Emission Factors, Volume I: Stationary Point and Area Sources (AP-42) or other
approved measurement procedures.

[40 CFR 60.764(c)]

(i) Collection systems: For the performance test required in 40 CFR 60.762(b)(2)(iii)(B), Method
25 or 25C (Method 25C may be used at the inlet only) of appendix A of 40 CFR Part 60 shall be
used to determine compliance with the 98 weight-percent efficiency or the 20 parts per million by
volume outlet concentration level, unless another method to demonstrate compliance has been
approved by the Administrator as provided by 40 CFR 60.767(c)(2). Method 3, 3A, or 3C shall
be used to determine oxygen for correcting the NMOC concentration as hexane to 3 percent. In
cases where the outlet concentration is less than 50 ppm NMOC as carbon (8 ppm NMOC as
hexane), Method 25A should be used in place of Method 25. Method 18 may be used in
conjunction with Method 25A on a limited basis (compound specific, e.g., methane) or Method
3C may be used to determine methane. The methane as carbon should be subtracted from the
Method 25A total hydrocarbon value as carbon to give NMOC concentration as carbon. The
landowner or operator shall divide the NMOC concentration as carbon by 6 to convert from the
CNMOC as carbon to CNMOC as hexane. Equation 4 below shall be used to calculate efficiency:

Control Efficiency = (NMOCin – NMOCout)/(NMOCin) (Eq. 4)

Where:

NMOCin = Mass of NMOC entering control device.

NMOCout = Mass of NMOC exiting control device.
[40 CFR 60.764(d)]
21

(j) Control systems: For the performance test required in 40 CFR 60.762(b)(2)(iii)(A), the net
heating value of the combusted landfill gas as determined in 40 CFR 60.18(f)(3) is calculated
from the concentration of methane in the landfill gas as measured by Method 3C. A minimum of
three 30-minute Method 3C samples are determined. The measurement of other organic
components, hydrogen, and carbon monoxide is not applicable. Method 3C may be used to
determine the landfill gas molecular weight for calculating the flare gas exit velocity under 40
CFR 60.18(f)(4).

(1) Within 60 days after the date of completing each performance test (as defined in 40 CFR
60.8), the permittee shall submit the results of the performance tests, including any associated
fuel analyses, required by 40 CFR 60.764(b) or (d) according to 40 CFR 60.767(i)(1).

(2) Reserved

[40 CFR 60.764(e)(1)-(2)].

(4) Each permittee of an MSW landfill having a design capacity equal to or greater than 2.5
million megagrams and 2.5 million cubic meters shall submit a collection and control
system design plan to the Administrator for approval within 1 year of the first NMOC
emission rate report in which the NMOC emission rate equals or exceeds 34 megagrams
per year, except as follows:

(i) If the permittee elects to recalculate the NMOC emission rate after Tier 2 NMOC
sampling and analysis as provided in Monitoring (c) above, and the resulting rate is
less than 34 megagrams per year, annual periodic reporting shall be resumed, using
the Tier 2 determined site-specific NMOC concentration, until the calculated
emission rate is equal to or greater than 34 megagrams per year or the landfill is
closed. The revised NMOC emission rate report, with the recalculated emission rate
based on NMOC sampling and analysis, shall be submitted, following the procedures
in paragraph (i)(2) below, within 180 days of the first calculated exceedance of 34
megagrams per year.

(ii) If the permittee elects to recalculate the NMOC emission rate after determining a
site-specific methane generation rate constant k, as provided in Tier 3 of Monitoring
(d), and the resulting NMOC emission rate is less than 34 Mg/yr, annual periodic
25

reporting shall be resumed. The resulting site-specific methane generation rate
constant k shall be used in the emission rate calculation until such time as the
emissions rate calculation results in an exceedance. The revised NMOC emission rate
report based on the provisions of Tier 3 of Monitoring (d) and the resulting site-
specific methane generation rate constant k shall be submitted, following the
procedure specified in paragraph (i)(2) below, to the Administrator within 1 year of
the first calculated emission rate equaling or exceeding 34 megagrams per year.

(iii) If the permittee elects to demonstrate that site-specific surface methane emissions are
below 500 parts per million methane, based on the provisions of Tier 4 of
Monitoring (f), then the permittee shall submit annually a Tier 4 surface emissions
report as specified in this paragraph following the procedure specified in paragraph
(i)(2) below until 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 landfill permittee may reduce Tier 4 monitoring from a
quarterly to an annual frequency. The Administrator may request such 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 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 permittee
shall determine the latitude and longitude coordinates using an instrument with an
accuracy of at least 4 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 that the landfill
does not exceed 50 Mg/yr of NMOC.

(A) 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 that site-specific surface methane emissions are
below 500 parts per million methane, and following the procedure specified in
paragraph (i)(2) below.

(B) The Tier 4 surface emissions report shall be submitted within 1 year of the first
measured surface exceedance of 500 parts per million methane, following the
procedure specified in paragraph (i)(2) below.

[40 CFR 60.767(c)(4)]

(5) The landfill permittee shall notify the Administrator that the design plan is completed and
submit a copy of the plan's signature page. The Administrator has 90 days to decide
whether the design plan should be submitted for review. If the Administrator chooses to
review the plan, the approval process continues as described in paragraph (c)(6) below.
However, if the Administrator indicates that submission is not required or does not
respond within 90 days, the landfill permittee can continue to implement the plan with
the recognition that the permittee is proceeding at their own risk. In the event that the
design plan is required to be modified to obtain approval, the permittee 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.

[40 CFR 60.767(c)(5)]
26

(6) Upon receipt of an initial or revised design plan, the Administrator shall review the
information submitted under paragraphs (c)(1) through (3) above and either approve it,
disapprove it, or request that additional information be submitted. Because of the many
site-specific factors involved with landfill gas system design, alternative systems may be
necessary. A wide variety of system designs are possible, such as vertical wells,
combination horizontal and vertical collection systems, or horizontal trenches only,
leachate collection components, and passive systems. If the Administrator does not
approve or disapprove the design plan, or does not request that additional information be
submitted within 90 days of receipt, then the permittee may continue with
implementation of the design plan, recognizing they would be proceeding at their own
risk.

[40 CFR 60.767(c)(6)]

(7) If the permittee chooses to demonstrate compliance with the emission control
requirements using a treatment system as defined in 40 CFR Part 60, Subpart XXX, then
the permittee shall prepare a site-specific treatment system monitoring plan as specified
in 40 CFR 60.768(b)(5).

[40 CFR 60.767(c)(7)]

(d) Revised design plan. The permittee who has already been required to submit a design plan
under paragraph (c) above shall submit a revised design plan to the Administrator for
approval as follows:

(1) At least 90 days before expanding operations to an area not covered by the previously
approved design plan.

(2) Prior to installing or expanding the gas collection system in a way that is not consistent
with the design plan that was submitted to the Administrator according to paragraph (c)
above.

[40 CFR 60.767(d)]

(e) Closure report. Each permittee of a controlled landfill shall submit a closure report to the
Administrator within 30 days of waste acceptance cessation. The Administrator may request
additional information as may be necessary to verify that permanent closure has taken place
in accordance with the requirements of 40 CFR 258.60. If a closure report has been submitted
to the Administrator, no additional wastes may be placed into the landfill without filing a
notification of modification as described under 40 CFR 60.7(a)(4).

[40 CFR 60.767(e)]
