solid waste acceptance rate is known, as specified in paragraphs (a)(1) and (2) of this
monitoring section, for part of the life of the landfill and the actual year-to-year solid waste
acceptance rate is unknown, as specified in paragraphs (a)(3) and (4) of this monitoring
section, for part of the life of the landfill. The values to be used in both Equation 1 and
Equation 2 are 0.05 per year for k, 170 cubic meters per megagram for Lo, and 4,000 parts
per million by volume as hexane for the CNMOC. For landfills located in geographical areas
with a 30-year annual average precipitation of less than 25 inches, as measured at the nearest
representative official meteorological site, the k value to be used is 0.02 per year.

(1) Equation 1 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 (Eq. 1)

Where,

MNMOC = Total NMOC emission rate from the landfill, megagrams per year.
k = Methane generation rate constant, per 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.
3.6 x 10 -9 = Conversion factor.

(2) 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.

(3) Equation 2 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 x10-9) (Eq. 2)
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, per 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 = 0 and e-kc = 1.
3.6 x10-9 = Conversion factor.

15

(4) 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.

(b) Tier 1. The permittee shall compare the calculated NMOC mass emission rate to the standard
of 34 megagrams per year.

(1) If the NMOC emission rate calculated in paragraph (a) of this monitoring section is less
than 34 megagrams per year, then the permittee shall submit an NMOC emission rate
report as provided according to paragraph (a) of reporting, and shall recalculate the
NMOC mass emission rate annually as required under paragraph (a) of this condition.

(2) If the NMOC emission rate calculated in paragraph (a) of this monitoring section is equal
to or greater than 34 megagrams per year, then the permittee shall either:

(i) Submit a gas collection and control system design plan within 1 year as specified in
40 CFR 62.16724(d) and install and operate a gas collection and control system
within 30 months according to 40 CFR 62.16714(b) and (c); or

(ii) Determine a site-specific NMOC concentration and recalculate the NMOC emission
rate using the Tier 2 procedures provided in paragraph (c) of this monitoring section,
or;

(iii) Determine a site-specific methane generation rate constant and recalculate the
NMOC emission rate using the Tier 3 procedures provided in paragraph (d) of this
monitoring section.

(c) Tier 2. The permittee shall determine the site-specific NMOC concentration using the
following sampling procedure. The permittee shall install at least two sample probes per
hectare, evenly distributed over the landfill surface that has retained waste for at least 2 years.
If the landfill is larger than 25 hectares in area, only 50 samples are required. The probes
should be evenly distributed across the sample area. The sample probes should be located to
avoid known areas of nondegradable solid waste. The permittee shall collect and analyze one
sample of landfill gas from each probe to determine the NMOC concentration using EPA
Method 25 or 25C of appendix A-7 of 40 CFR part 60. Taking composite samples from
different probes into a single cylinder is allowed; however, equal sample volumes must be
taken from each probe. For each composite, the sampling rate, collection times, beginning
and ending cylinder vacuums, or alternative volume measurements shall be recorded to verify
that composite volumes are equal. Composite sample volumes should not be less than one
liter unless evidence can be provided to substantiate the accuracy of smaller volumes.
Terminate compositing before the cylinder approaches ambient pressure where measurement
accuracy diminishes. If more than the required number of samples is taken, all samples shall
be used in the analysis. The permittee shall divide the NMOC concentration from EPA
Method 25 or 25C of appendix A-7 of 40 CFR part 60 by 6 to convert from CNMOC as
carbon to CNMOC as hexane. If the landfill has an active or passive gas removal system in
place, EPA Method 25 or 25C samples may be collected from these systems instead of
surface probes provided the removal system can be shown to provide sampling as
representative as the two sampling probes per hectare requirement. For active collection
systems, samples may be collected from the common header pipe. The sample location on the
common header pipe shall be before any gas moving, condensate removal, or treatment
16

system equipment. For active collection systems, a minimum of three samples shall be
collected from the header pipe.

(1) Within 60 days after the date of determining the NMOC concentration and corresponding
NMOC emission rate, the permittee shall submit the results according to paragraph (d) of
reporting.

(2) The permittee shall recalculate the NMOC mass emission rate using Equation 1 or
Equation 2 provided in paragraph (a)(1) or (3) of this monitoring section using the
average site-specific NMOC concentration from the collected samples instead of the
default value provided in paragraph (a) of this monitoring section.

(3) If the resulting NMOC mass emission rate is less than 34 megagrams per year, then the
permittee shall submit a periodic estimate of NMOC emissions in an NMOC emission
rate report according to paragraph (a) of reporting and shall recalculate the NMOC mass
emission rate annually as required in paragraph (a) of this condition. The site-specific
NMOC concentration must be retested every 5 years using the methods specified in this
monitoring section.

(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 shall
either:

(i) Submit a gas collection and control system design plan within 1 year as specified in
40 CFR 62.16724(d) and install and operate a gas collection and control system
within 30 months according to 40 CFR 62.16714(b) and (c);

(ii) Determine a site-specific methane generation rate constant and recalculate the
NMOC emission rate using the site-specific methane generation rate using the Tier 3
procedures specified in paragraph (d) of this monitoring section; or

(iii) Conduct a surface emission monitoring (SEM) demonstration using the Tier 4
procedures specified in paragraph (f) of this monitoring section.

(d) Tier 3. The site specific methane generation rate constant shall be determined using the
procedures provided in Method 2E of appendix A of 40 CFR part 60. The permittee shall
estimate the NMOC mass emission rate using Equation 1 or Equation 2 in paragraph (a) of
this monitoring section and using a site specific methane generation rate constant, and the site
specific NMOC concentration as determined in paragraph (c) of this monitoring section
instead of the default values provided in paragraph (a) of this monitoring section. The
permittee shall compare the resulting NMOC mass emission rate to the standard of 34
megagrams per year.

(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 shall either:

(i) Submit a gas collection and control system design plan within 1 year as specified in
40 CFR 62.16724(d) and install and operate a gas collection and control system
within 30 months according to 40 CFR 62.16714(b) and (c); or

17

(ii) Conduct a surface emission monitoring demonstration using the Tier 4 procedures
specified in paragraph (f) of this monitoring section.

(2) If the NMOC mass emission rate is less than 34 megagrams per year, then the permittee
shall recalculate the NMOC mass emission rate annually using Equation 1 or Equation 2
in paragraph (a) of this monitoring section and using the site-specific Tier 2 NMOC
concentration and Tier 3 methane generation rate constant and submit a periodic NMOC
emission rate report as provided in paragraph (a) of reporting. The calculation of the
methane generation rate constant is performed only once, and the value obtained from
this test shall be used in all subsequent annual NMOC emission rate calculations.

(e) 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) of this monitoring section if the method has been approved by the EPA
Administrator.

(f) Tier 4. Demonstrate that surface methane emissions are below 500 parts per million. Surface
emission monitoring (SEM) shall 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 megagrams per year but less than 50 megagrams per year using
Tier 1 or Tier 2. If both Tier 1 and Tier 2 indicate NMOC emissions are 50 megagrams per
year or greater, then Tier 4 cannot be used. In addition, the landfill must meet the criteria in
paragraph (f)(6) of this monitoring section.

(1) 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 62.16720(d).

(2) The background concentration shall be determined by moving the probe inlet upwind and
downwind at least 30 meters from the waste mass boundary of the landfill.

(3) Surface emission monitoring (SEM) shall be performed in accordance with section 8.3.1
of EPA Method 21 of appendix A-7 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.

(i) The permittee shall 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 SEM monitor, and must be placed on the ground, to ensure wind
turbulence is blocked. The SEM cannot be conducted if average wind speed exceeds
25 miles per hour.

(ii) 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 shall also be monitored using a device meeting the specifications
provided in 40 CFR 62.16720(d).
18

(4) A permittee seeking to comply with the Tier 4 provisions in paragraph (a)(6) of this
monitoring section shall maintain records of surface emission monitoring as provided in
40 CFR 62.16726(g) and submit a Tier 4 surface emissions report as provided in 40 CFR

from the surface of the landfill, the permittee shall submit a gas collection and control
system design plan within 1 year of the first measured concentration of methane of 500
parts per million or greater from the surface of the landfill according to 40 CFR
62.16724(d) and install and operate a gas collection and control system according to 40
CFR 62.16714(b) and (c) within 30 months of the most recent NMOC emission rate
report in which the NMOC emission rate equals or exceeds 34 megagrams per year based
on Tier 2.

(6) If after four consecutive quarterly monitoring periods at a landfill, other than a closed
landfill, there is no measured concentration of methane of 500 parts per million or greater
from the surface of the landfill, the permittee shall continue quarterly surface emission
monitoring using the methods specified in this monitoring section.

(7) If after four consecutive quarterly monitoring periods at a closed landfill there is no
measured concentration of methane of 500 parts per million or greater from the surface of
the landfill, the permittee shall conduct annual surface emission monitoring using the
methods specified in this monitoring section.

(8) If a landfill has installed and operates a collection and control system that is not required
by this subpart, then the collection and control system must meet the following criteria:

(i) The gas collection and control system must have operated for at least 6,570 out of
8,760 hours preceding the Tier 4 SEM demonstration.

(ii) During the Tier 4 SEM demonstration, the gas collection and control system must
operate as it normally would to collect and control as much landfill gas as possible

(g) When calculating emissions for Prevention of Significant Deterioration purposes, the
permittee of each MSW landfill subject to the provisions of this subpart 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 of this chapter using Compilation
of Air Pollutant Emission Factors, Volume I: Stationary Point and Area Sources (AP-42) or
other approved measurement procedures.

equal to or greater than 2.5 million megagrams and 2.5 million cubic meters, the permittee
shall submit a NMOC emission rate report following the procedure specified in paragraph (d)
of this reporting section no later than 90 days after the effective date of this subpart. The
permittee shall submit the NMOC emission rate report to the Director annually following the
procedure specified in paragraph (d) of this reporting section, except as provided for in
paragraph (a)(3) of this reporting section. The Director may request such additional
information as may be necessary to verify the reported NMOC emission rate.

(1) The NMOC emission rate report shall contain an annual or 5-year estimate of the NMOC
emission rate calculated using the formula and procedures provided in paragraphs (a)
through (f) of monitoring, as applicable.

(2) The NMOC emission rate report shall include all the data, calculations, sample reports
and measurements used to estimate the annual or 5-year emissions.

(3) 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 (d) of this reporting
section, an estimate of the NMOC emission rate for the next 5-year period in lieu of the
annual report. This estimate shall 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
shall be provided to the Director. This estimate shall 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 shall be submitted to
the Director. The revised estimate shall cover the 5-year period beginning with the year
in which the actual waste acceptance rate exceeded the estimated waste acceptance rate.

(4) The permittee subject to the requirements of 40 CFR 62 Subpart OOO is exempted from
the requirements to submit an NMOC emission rate report, after installing a collection
and control system that complies with 40 CFR 62.16714(b) and (c), during such time as
the collection and control system is in operation and in compliance with 40 CFR
62.16716 and 40 CFR 62.16720.

21

(b) The permittee of an MSW landfill with a design capacity equal to or greater than 2.5 million
megagrams and 2.5 million cubic meters shall submit a copy of the collection and control
system design plan cover page that contains the engineer’s seal to the Director 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:

(1) If the permittee elects to recalculate the NMOC emission rate after Tier 2 NMOC
sampling and analysis as provided in paragraph (c) of monitoring 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 NMOC
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 NMOC emission rate
based on NMOC sampling and analysis, shall be submitted, following the procedure in
paragraph (d) of this reporting section, within 180 days of the first calculated exceedance
of 34 megagrams per year.

(2) 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 in paragraph (d) of
monitoring, and the resulting NMOC emission rate is less than 34 megagrams per year,
annual periodic reporting shall be resumed. The resulting site-specific methane
generation rate constant k shall be used in the NMOC 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 paragraph (d) of monitoring and the
resulting site-specific methane generation rate constant k shall be submitted, following
the procedure specified in paragraph (d) of this reporting section, to the Director within 1
year of the first calculated NMOC emission rate equaling or exceeding 34 megagrams per
year.

(3) If the permittee elects to demonstrate that site-specific surface methane emissions are
below 500 parts-per-million methane, based on the provisions in paragraph (f) of
monitoring, then the permittee shall submit annually a Tier 4 surface emissions report as
specified in this paragraph following the procedure specified in paragraph (d) of this
reporting section until a surface emissions reading 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 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 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

II.B.2.b Condition:

The permittee shall meet one of the following requirements for all asbestos disposal operations at the
landfill:

(1) There shall be no visible emissions to the outside air from any active waste disposal site where
asbestos-containing waste material has been deposited,

(2) At the end of each operating day, or at least once every 24-hour period while the site is in continuous
operation, the asbestos-containing waste material that has been deposited at the site during the operating
day or previous 24-hour period shall:

(a) Be covered with at least 15 centimeters (6 inches) of compacted nonasbestos-containing material, or

(b) Be covered with a resinous or petroleum-based dust suppression agent that effectively binds dust and
controls wind erosion. Such an agent shall be used in the manner and frequency recommended for the
particular dust by the dust suppression agent manufacturer to achieve and maintain dust control. Other
equally effective dust suppression agents may be used upon prior approval by the Director. For purposes
of this paragraph, any used, spent, or other waste oil is not considered a dust suppression agent.

(3) Use an alternative emissions control method that has received prior written approval by the U.S.
Environmental Protection Agency (USEPA) according to the procedures described in 40 CFR
61.149(c)(2). [Origin: 40 CFR 61.154]. [40 CFR 61 Subpart M]

II.B.2.b.1 Monitoring:

If the permittee chooses to comply with the no visible emissions provisions of this condition, a
visual opacity observation of each active asbestos disposal site shall be performed on a daily basis
in accordance with 58 FR 61640 Method 203C.
23

If the permittee chooses to comply with the daily cover provisions of this condition, a visual
inspection of the site(s) where asbestos containing waste material is deposited shall be conducted
daily to verify compliance with this condition.

II.B.2.b.2 Recordkeeping:

If the permittee chooses to comply with the no visible emissions provisions of this condition, a
log of the visual opacity observations shall be maintained as described in Provision S.1 in Section
I of this permit. All data required by 40 CFR 60, Appendix A, Method 9 or 58 FR 61640,
Method 203C shall also be maintained as described in Provision S.1 in Section I of this permit.

If the permittee chooses to comply with the daily cover provisions of this condition, results of
daily visual inspections shall be recorded in a log and maintained as described in Provision S.1 in
Section I of this permit.

II.B.2.b.3 Reporting:

There are no reporting requirements for this provision except those specified in Section I of this
permit.

Status: In Compliance. Asbestos shipment manifest records have been kept. A log sheet is filled out for
each shipment and records controls taken. Waste is covered immediately with at least six inches of
non-asbestos containing material (usually 24 inches of dirt). No visible emissions were observed at
the asbestos cell. A sign is posted at the entrance to the active asbestos cell, and a hill surrounding
the cell deters public access. There are no closed asbestos-containing cells.

II.B.2.c Condition:

Upon closure of an asbestos-containing waste disposal site, the permittee shall submit a copy of records
of asbestos waste disposal locations and quantities and shall:

disposal site or

(b) Cover the asbestos-containing waste material with at least 15 centimeters (6 inches) of compacted
nonasbestos-containing material, and grow and maintain a cover of vegetation on the area adequate to
prevent exposure of the asbestos-containing waste material. In desert areas where vegetation would be
difficult to maintain, at least 8 additional centimeters (3 inches) of well-graded, nonasbestos crushed rock
may be placed on top of the final cover instead of vegetation and maintained to prevent emissions; or

(c) Cover the asbestos-containing waste material with at least 60 centimeters (2 feet) of compacted
nonasbestos-containing material, and maintain it to prevent exposure of the asbestos-containing waste; or

(d) For inactive waste disposal sites for asbestos tailings, a resinous or petroleum-based dust suppression
agent that effectively binds dust to control surface air emissions may be used instead of the methods in
paragraphs (a) (1), (2), and (3) of this section. Use the agent in the manner and frequency recommended
for the particular asbestos tailings by the manufacturer of the dust suppression agent to achieve and
maintain dust control. Obtain prior written approval of USEPA to use other equally effective dust
suppression agents. For purposes of this paragraph, any used, spent, or other waste oil is not considered a
24

dust suppression agent.

(2) Unless a natural barrier adequately deters access by the general public, install and maintain warning
signs and fencing as follows, or comply with paragraph (a)(2) or (a)(3) of this condition:
