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 part of the
life of the landfill and the actual year to year solid waste acceptance rate is 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
15

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)]

(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. [40 CFR 60.764(a)(1)(ii)(A)-(B)].

(b) Tier 1. The permittee shall compare the calculated NMOC mass emission rate to the standard
of 34 megagrams per year. [40 CFR 60.764(a)(2)]

(1) If the NMOC emission rate calculated in paragraph (a), above, is less than 34 megagrams per
year, then the permittee shall submit an NMOC emission rate report according to Reporting (a),
and shall recalculate the NMOC mass emission rate annually as required by Condition (a)(1).
[40 CFR 60.764(a)(2)(i)]

(2) If the calculated NMOC emission rate is equal to or greater than 34 megagrams per year as
calculated by paragraph (a) above, then the permittee shall either: submit a gas collection and
control system design plan within 1 year as specified in 40 CFR 60.767(c) and install and operate
a gas collection and control system within 30 months according to 40 CFR 60.762(b)(2)(ii) and
(iii), determine a site specific NMOC concentration and recalculate the NMOC emission rate
using the Tier 2 procedures provided in paragraph(c) below, or determine a site-specific methane
generation rate constant and recalculate the NMOC emission rate using the Tier 3 procedures
provided in paragraph (d) below. [40 CFR 60.764(a)(2)(ii)].

(c) Tier 2. The permittee shall determine the site-specific NMOC concentration using the
sampling procedures described in 40 CFR 60.764(a)(3). [40 CFR 60.764(a)(3)]

16

(1) Within 60 days after the date of completing each performance test (as defined in 40 CFR
60.8), the permittee must submit the results according to Reporting (i)(1).
[40 CFR 60.764(a)(3)(i)]

(2) The permittee must recalculate the NMOC mass emission rate using the equation provided in
paragraph (a)(1) or (a)(2) above and using the average site-specific NMOC concentration from
the collected samples instead of the default value provided in paragraph (a) above. [40 CFR
60.764(a)(3)(ii)]

(3) If the resulting NMOC mass emission rate is less than 34 megagrams per year, then the
permittee must submit a periodic estimate of NMOC emissions in an NMOC emission rate report
according to Reporting (a)(1), and must recalculate the NMOC mass emission rate annually as
required under Condition (a)(1)(ii). The site-specific NMOC concentration must be retested every
5 years using the methods specified in this Monitoring section. [40 CFR 60.764(a)(3)(iii)]

(4) If the NMOC mass emission rate as calculated using the Tier 2 site-specific NMOC
concentration is equal to or greater than 34 megagrams per year, the permittee must either

(i) Submit a gas collection and control system design plan within 1 year as specified in 40 CFR

(d) Tier 3. The site specific methane generation rate constant shall be determined using the
procedures provided in 40 CFR 60 Appendix A Method 2E. The permittee shall estimate the
NMOC mass emission rate using equations in paragraph (a) above and using a site specific
methane generation rate constant k, and the site specific NMOC concentration as determined in
paragraph (c) above instead of the default values provided in paragraph (a) above. The permittee
shall compare the resulting NMOC mass emission rate to the standard of 34 megagrams per year.
[40 CFR 60.764(a)(4)]

(1) If the NMOC mass emission rate as calculated using the Tier 2 site-specific NMOC
concentration and Tier 3 site-specific methane generation rate is equal to or greater than 34
megagrams per year, the permittee must either:

(i) Submit a gas collection and control system design plan within 1 year as specified in 40 CFR
60.767(c) and install and operate a gas collection and control system within 30 months according
to 40 CFR 60.762(b)(2)(ii) and (iii); or

recalculate the NMOC mass emission rate annually using the equation provided in paragraph
(a)(1) or (a)(2) above and using the site-specific Tier 2 NMOC concentration and Tier 3 methane
17

generation rate constant and submit a periodic NMOC emission rate report as provided in 40 CFR
60.767(b)(1). The calculation of the methane generation rate constant is performed only once, and
the value obtained from this test must be used in all subsequent annual NMOC emission rate
calculations. [40 CFR 60.754(a)(4)(ii)]

(e) Other methods. The permittee may use other methods to determine the NMOC concentration
or a site-specific methane generation rate constant as an alternative to the methods required in
paragraphs (c) and (d) above if the method has been approved by the Director. [40 CFR
60.764(a)(5)].

(f) Tier 4. The permittee must demonstrate that surface methane emissions are below 500 parts
per million. Surface emission monitoring must be conducted on a quarterly basis using the
following procedures. Tier 4 is allowed only if the permittee can demonstrate that NMOC
emissions are greater than or equal to 34 Mg/yr but less than 50 Mg/yr using Tier 1 or Tier 2. If
both Tier 1 and Tier 2 indicate NMOC emissions are 50 Mg/yr or greater, then Tier 4 cannot be
used. In addition, the landfill must meet the criteria in paragraph (f)(viii) below. [40 CFR
60.764(a)(6)]

(i) The permittee must measure surface concentrations of methane along the entire perimeter of
the landfill and along a pattern that traverses the landfill at no more than 30-meter intervals using
an organic vapor analyzer, flame ionization detector, or other portable monitor meeting the
specifications provided in 40 CFR 60.765(d). [40 CFR 60.764(a)(6)(i)]

(ii) The background concentration must be determined by moving the probe inlet upwind and
downwind at least 30 meters from the waste mass boundary of the landfill [40 CFR
60.764(a)(6)(ii)]

(iii) Surface emission monitoring must be performed in accordance with section 8.3.1 of Method
21 of appendix A of 40 CFR Part 60, except that the probe inlet must be placed no more than 5
centimeters above the landfill surface; the constant measurement of distance above the surface
should be based on a mechanical device such as with a wheel on a pole, except as described in
paragraph (A) below. [40 CFR 60.764(a)(6)(iii)]

(A) The permittee must use a wind barrier, similar to a funnel, when onsite average wind speed
exceeds 4 miles per hour or 2 meters per second or gust exceeding 10 miles per hour. Average
on-site wind speed must also be determined in an open area at 5-minute intervals using an on-site
anemometer with a continuous recorder and data logger for the entire duration of the monitoring
event. The wind barrier must surround the surface emissions monitor (SEM), and must be placed
on the ground, to ensure wind turbulence is blocked. SEM cannot be conducted if average wind
speed exceeds 25 miles per hour. [40 CFR 60.764(a)(6)(iii)(A)]

(B) Landfill surface areas where visual observations indicate elevated concentrations of landfill
gas, such as distressed vegetation and cracks or seeps in the cover, and all cover penetrations
must also be monitored using a device meeting the specifications provided in 40 CFR 60.765(d).
[40 CFR 60.764(a)(6)(iii)(B)]

(iv) Permittee seeking to comply with the Tier 4 provisions in paragraph (f) of this Monitoring
section must maintain records of surface emission monitoring as provided in 40 CFR 60.768(g)
and submit a Tier 4 surface emissions report as provided in Reporting (c)(4)(iii). [40 CFR
60.764(a)(6)(iv)]

18

(g) NMOC emission rate for capping, removing, or decommissioning collection and control
system. After the installation and startup of a collection and control system in compliance with
this subpart, the permittee must 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.

(1) The flow rate of landfill gas, QLFG, must 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, must 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 must be before any condensate removal or other gas refining units. The
permittee must 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 Director.

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

(ii) [Reserved] [40 CFR 60.764(b)(1)-(3)]

(h) PSD. When calculating emissions for Prevention of Significant Deterioration purposes, the
permittee must 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 must 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 Director as provided by 40 CFR 60.767(c)(2). Method 3, 3A, or 3C must 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
19

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 permittee must divide
the NMOC concentration as carbon by 6 to convert from the CNMOC as carbon to CNMOC as
hexane. Equation 4 below must 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)]

(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 must 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)].

II.B.2.a.2 Recordkeeping:

(a) The permittee shall maintain records required under 40 CFR Part 60.768(a)-(f), as they apply.

(b) Site-specific surface methane emissions demonstration. Permittee seeking to demonstrate that
site-specific surface methane emissions are below 500 parts per million by conducting surface
emission monitoring under the Tier 4 procedures above must keep for at least 5 years up-to-date,
readily accessible records of all surface emissions monitoring and information related to
monitoring instrument calibrations conducted according to sections 8 and 10 of Method 21 of
appendix A of 40 CFR Part 60, including all of the following items:

monitoring demonstration.

(3) Timestamp of each surface scan reading:

(i) Timestamp should be detailed to the nearest second, based on when the sample collection
begins.

(ii) A log for the length of time each sample was taken using a stopwatch (e.g., the time the probe
was held over the area).

(4) Location of each surface scan reading. The permittee must determine the coordinates using an
instrument with an accuracy of at least 4 meters. Coordinates must be in decimal degrees with at
least five decimal places.

(5) Monitored methane concentration (parts per million) of each reading.

(6) Background methane concentration (parts per million) after each instrument calibration test.

(7) Adjusted methane concentration using most recent calibration (parts per million).

(c) Collection and control system monitoring data. Except as provided in 40 CFR 60.767(c)(2),
the permittee must keep for at least 5 years up-to-date, readily accessible records of all collection
and control system monitoring data for parameters measured in 40 CFR 60.766(a)(1), (2), and
(3), as applies. [40 CFR 60.768(h)]

(d) Electronic records. Any records required to be maintained by 40 CFR Part 60, Subpart XXX
that are submitted electronically via the EPA's CDX may be maintained in electronic format. [40
CFR 60.768(i)]

(e) Leachate or liquids addition. Permittee reporting leachate or other liquids addition under
Reporting (k) must keep records of any engineering calculations or company records used to
estimate the quantities of leachate or liquids added, the surface areas for which the leachate or
liquids were applied, and the estimates of annual waste acceptance or total waste in place in the
areas where leachate or liquids were applied. [40 CFR 60.768(j)]

(f) Results of monitoring shall also be maintained in accordance with provision I.S.1 of this
permit.

21

II.B.2.a.3 Reporting:

(a) NMOC emission rate report. The permittee must submit an NMOC emission rate report
following the procedure specified in paragraph (i)(2) below to the Director initially and annually
thereafter, except as provided for in paragraph (a)(1)(ii) below. The Director may request such
additional information as may be necessary to verify the reported NMOC emission rate. [40 CFR
60.767(b)]

(1) The NMOC emission rate report must contain an annual or 5-year estimate of the NMOC
emission rate calculated using the formula and procedures provided in Monitoring (a)-(f) or (g),
as applicable. [40 CFR 60.767(b)(1)]

(i) The initial NMOC emission rate report must be submitted no later than indicated in paragraphs
(A) and (B) below. Subsequent NMOC emission rate reports must be submitted annually
thereafter, except as provided for in paragraph (a)(1)(ii) below. [40 CFR 60.767(b)(1)(i)]

(A) November 28, 2016, for landfills that commenced construction, modification, or
reconstruction after July 17, 2014, but before August 29, 2016, or [40 CFR 60.767(b)(1)(i)(A)]

(B) Ninety days after the date of commenced construction, modification, or reconstruction for
landfills that commence construction, modification, or reconstruction after August 29, 2016. [40
CFR 60.767(b)(1)(i)(B)]

(ii) If the estimated NMOC emission rate as reported in the annual report to the Director is less
than 34 megagrams per year in each of the next 5 consecutive years, the permittee may elect to
submit, following the procedure specified in paragraph (i)(2) below, an estimate of the NMOC
emission rate for the next 5-year period in lieu of the annual report. This estimate must include
the current amount of solid waste-in-place and the estimated waste acceptance rate for each year
of the 5 years for which an NMOC emission rate is estimated. All data and calculations upon
which this estimate is based must be provided to the Director. This estimate must be revised at
least once every 5 years. If the actual waste acceptance rate exceeds the estimated waste
acceptance rate in any year reported in the 5-year estimate, a revised 5-year estimate must be
submitted to the Director. The revised estimate must cover the 5-year period beginning with the
year in which the actual waste acceptance rate exceeded the estimated waste acceptance rate. [40
CFR 60.767(b)(1)(ii)]

(2) The NMOC emission rate report must include all the data, calculations, sample reports and
measurements used to estimate the annual or 5-year emissions. [40 CFR 60.767(b)(2)]

(3) Permittee subject to the requirements of this subpart is exempted from the requirements to
submit an NMOC emission rate report, after installing a collection and control system that
complies with 40 CFR 60.762(b)(2), during such time as the collection and control system is in
operation and in compliance with 40 CFR 60.763 and 40 CFR 60.765. [40 CFR 60.767(b)(3)]

(b) Reserved. [40 CFR 60]

(c) Collection and control system design plan. The permittee subject to Condition (a)(2) must
submit a collection and control system design plan to the Director for approval according to the
schedule in paragraph (c)(4) below. The collection and control system design plan must be
prepared and approved by a professional engineer and must meet the following requirements:
22

(1) The collection and control system as described in the design plan must meet the design
requirements in 40 CFR 60.762(b)(2). [40 CFR 60.767(c)(1)]

(2) The collection and control system design plan must include any alternatives to the operational
standards, test methods, procedures, compliance measures, monitoring, recordkeeping or
reporting provisions of 40 CFR 60.763 through 60.768 proposed by the permittee. [40 CFR
60.767(c)(2)]

(3) The collection and control system design plan must either conform with specifications for
active collection systems in 40 CFR 60.769 or include a demonstration to the Director's
satisfaction of the sufficiency of the alternative provisions to 40 CFR 60.769. [40 CFR
60.767(c)(3)]

(4) The permittee must submit a collection and control system design plan to the Director 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 must 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, must 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 reporting must be resumed. The
resulting site-specific methane generation rate constant k must 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 must be submitted, following the procedure
specified in paragraph (i)(2) below, to the Director 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 must 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 permittee may reduce Tier 4 monitoring from a quarterly to
an annual frequency. The Director may request such additional information as may be necessary
to verify the reported instantaneous surface emission readings. The Tier 4 surface emissions
report must 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, you must
determine the latitude and longitude coordinates using an instrument with an accuracy of at least
4 meters. The coordinates must be in decimal degrees with at least five decimal places. The Tier 4
23

surface emission report must 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 must 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 must 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 permittee must notify the Director that the design plan is completed and submit a copy of
the plan's signature page. The Director has 90 days to decide whether the design plan should be
submitted for review. If the Director chooses to review the plan, the approval process continues
as described in paragraph (c)(6) below. However, if the Director indicates that submission is not
required or does not respond within 90 days, the 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 must 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)].

(6) Upon receipt of an initial or revised design plan, the Director must 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
Director 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
