PROCESS
DESCRIPTION:
Holcim (US) Inc. operates the Devil's Slide cement manufacturing plant near
Morgan, Utah. This plant has been in operation since 1907, with recent major
modifications made to most of the process during 1996 and 1997. At the
Devil's Slide plant, cement is made when raw materials such as limestone and
sandstone (quarried on-site), iron ore, bottom ash, and clay are proportioned,
ground, and mixed, and then fed into an inline rotating kiln. The intense heat
of the kiln alters the materials and recombines them into small stones called
cement clinker. The clinker is cooled and ground with gypsum into a fine
powdered cement. The final product is stored on site for later packaging and
shipping. The major sources of air emissions are the combustion of fuels for
the kiln operation and from the kiln and clinker cooling process. The Devil's
Slide plant is a major source for emissions of PM10, SO2, NOx, CO, VOC, and
HAPs. This source is subject to 40 CFR 60 Subpart A-General Provisions, 40
CFR 60 Subpart Y-Standards of Performance for Coal Preparation and
Processing Plants, 40 CFR 60 Subpart OOO-Standards of Performance for
Nonmetallic Mineral Processing Plants, 40 CFR 63 Subpart A-General
Provisions, 40 CFR 63 Subpart LLL-National Emission Standards for
Hazardous Air Pollutants from the Portland Cement Manufacturing Industry,
40 CFR 63 Subpart ZZZZ-National Emission Standards for Hazardous Air
Pollutants for Stationary Reciprocating Internal Combustion Engines.

According to the real time electronic tracking system the temperatures appeared
below the established temperatures at time of the inspection. The next D/F stack test
will be due in January of 2025.

Stack Test Summary:
Stacks New Established Temperatures (Degrees C)
Main Baghouse - Mill On 279.1
Main Baghouse - Mill Off 359.9
Alkali Baghouse - Mill On 271.3
Alkali Baghouse – Mill Off 353.4

II.B.6.h Condition:

Emissions of Dioxins/Furans (D/F) shall be no greater than 0.2 ng/dscm (TEQ) on a dry
basis, corrected to 7 percent oxygen during normal operation. If the average temperature at
the inlet to the first PM control device (fabric filter or electrostatic precipitator) during the

a. The permittee shall verify the calibration of the device at least once every
three months

b. Each hour, the permittee shall calculate the three-hour rolling average
activated carbon injection rate for the previous three hours of process
operation. See 40 CFR 63.1349(b)(3).

c. When the operating status of the raw mill of the in-line kiln/raw mill is
changed from off to on or from on to off, the calculation of the three-hour
rolling average activated carbon injection rate shall begin anew, without
considering previous recordings.

43
(ii) If activated carbon injection is used to comply with the D/F emissions
limitation, the permittee shall demonstrate compliance using a CMS. The
permittee shall install, operate, calibrate, and maintain a continuous monitor
to record the activated carbon injection system carrier gas parameter (either
the carrier gas flow rate or the carrier gas pressure drop) established during
the D/F performance test in accordance with 40 CFR 63.1349(b)(3). Each
hour, the permittee shall calculate the three-hour rolling average of the
selected parameter value for the previous 3 hours of process operation using
all of the one-minute data available (i.e., the CMS is not out-of-control.)

(iii) If carbon injection is employed as an emission control technique, the
permittee shall comply with the additional monitoring requirements of 40
CFR 63.1350(m)(1) through (m)(4) and (m)(9).

[DAQE-AN100070027-20]. [R307-401-8]

II.B.6.j.1 Monitoring:

The PM performance tests shall be performed using Method 5 or 5I and consist of three
test runs. (40 CFR 63.1343 Table 1 Footnote 1)

The permittee shall demonstrate compliance with the emissions standards and operating
limits by using the test methods and procedures in 40 CFR 63.1349 and 40 CFR 63.7.
(40 CFR 63.1348(a)) At least 60 days before the test, the source shall notify the Director
of the date, time, place of testing, and submit a source test protocol containing the items in
R307-165-3

(a) The permittee shall demonstrate compliance with the PM emissions standards by
using the following test methods and procedures. Initial compliance shall be
demonstrated by conducting a performance test using Method 5 or Method 5I in
40 CFR 60 Appendix A-3. The permittee shall also monitor continuous
performance through use of a PM continuous parametric monitoring system (PM
CPMS).

(i) The permittee shall establish a site-specific operating limit for the PM CPMS.
The permittee shall use the PM CPMS to demonstrate continuous compliance
with the operating limit.

a. The PM CPMS shall provide a 4-20 milliamp or digital signal output and
the establishment of its relationship to manual reference method
measurements shall be determined in units of milliamps or the monitor's
digital equivalent

b. The PM CPMS operating range shall be capable of reading PM
concentrations from zero to a level equivalent to three times the allowable
emission limit. If the PM CPMS is an auto-ranging instrument capable of
multiple scales, the primary range of the instrument shall be capable of
reading PM concentration from zero to a level equivalent to three times
the allowable emission limit

c. During the initial performance test or any such subsequent performance
test that demonstrates compliance with the PM limit, the permittee shall
record and average all milliamp or digital output values from the PM
CPMS for the periods corresponding to the compliance test runs (e.g.,
average all the PM CPMS output values for three corresponding Method
5I test runs).

(ii) The permittee shall determine the operating limit as specified in paragraphs
(iii) through (iv). If the PM performance test demonstrates PM emission levels
to be below 75 percent of the emission limit the permittee shall use the
average PM CPMS value recorded during the PM compliance test, the
46
milliamp or digital equivalent of zero output from the PM CPMS, and the
average PM result of the compliance test to establish the operating limit. If the
PM compliance test demonstrates PM emission levels to be at or above 75
percent of the emission limit the permittee shall use the average PM CPMS
value recorded during the PM compliance test to establish the operating limit.
The permittee shall verify an existing or establish a new operating limit after
each repeated performance test. The permittee shall repeat the performance
test at least annually and reassess and adjust the site-specific operating limit in
accordance with the results of the performance test

(iii) If the average of the three Method 5 or 5I compliance test runs is below 75
percent of the PM emission limit, the permittee shall calculate an operating
limit by establishing a relationship of PM CPMS signal to PM concentration
using the PM CPMS instrument zero, the average PM CPMS values
corresponding to the three compliance test runs, and the average PM
concentration from the Method 5 or 5I compliance test with the procedures in
(iii)(A) through (D).

a. Determine the PM CPMS instrument zero output with one of the
procedures specified in 40 CFR 63.1349(b)(1)(iii)(A).

b. Determine the PM CPMS instrument average in milliamps or digital
equivalent, and the average of the corresponding three PM compliance test
runs, as specified in 40 CFR 63.1349(b)(1)(iii)(B).

c. With the instrument zero expressed in milliamps or a digital value, the
three run average PM CPMS milliamp or digital signal value, and the
three run PM compliance test average, determine a relationship of lb/ton-
clinker per milliamp or digital signal value as specified in 40 CFR
63.1349(b)(1)(iii)(C)

d. Determine the source specific 30-day rolling average operating limit using
the lb/ton-clinker per milliamp or digital signal value as specified in 40
CFR 63.1349(b)(1)(iii)(D). This sets the operating limit at the PM CPMS
output value corresponding to 75 percent of the emission limit.

(iv) If the average of the three PM compliance test runs is at or above 75 percent
of the PM emission limit the permittee shall determine the operating limit by
averaging the PM CPMS milliamp or digital equivalent output corresponding
to the three PM performance test runs that demonstrate compliance with the
emission limit as specified in 40 CFR 63.1349(b)(1)(iv).

(v) To determine continuous operating compliance, the permittee shall record the
PM CPMS output data for all periods when the process is operating, and use
all the PM CPMS data for calculations when the source is not out-of-control.
The permittee shall demonstrate continuous compliance by using all quality-
assured hourly average data collected by the PM CPMS for all operating hours
to calculate the arithmetic average operating parameter in units of the
operating limit (milliamps or the digital equivalent) on a 30 operating day
rolling average basis, updated at the end of each new kiln operating day. The
permittee shall determine the 30 kiln operating day average as specified in 40
CFR 63.1349(b)(1)(v).
47

(vi) For each performance test, the permittee shall conduct at least three separate
test runs under the conditions that exist when the affected source is operating
at the level reasonably expected to occur. Conduct each test run to collect a
minimum sample volume of 1 dscm for determining compliance with an
existing source limit. Calculate the time weighted average of the results from
three consecutive runs, including applicable sources, to determine compliance.
Determination of the particulate matter collected in the impingers ('back half')
of the Method 5 or Method 5I particulate sampling train is not required to
demonstrate compliance with the PM standards. For kilns with inline raw
mills, testing shall be conducted while the raw mill is on and while the raw
mill is off.

As part of demonstration of compliance with the PM10 limit, all of the
filterable particulate emissions measured shall be considered PM10. Every
three years, the permittee shall use 40 CFR 51, Appendix M, Method 202 or
other EPA-approved testing method, as acceptable to the Director, to measure
condensable PM. The back-half condensables shall not be used for PM10
compliance demonstration but shall be used for inventory purposes

(vii) The permittee shall demonstrate initial compliance by conducting separate
performance tests while the raw mill is under normal operating conditions and
while the raw mill is not operating, and calculate the time weighted average
emissions. The operating limit shall then be determined using 40 CFR
63.1349(b)(1)(i).

(viii) When there is an alkali bypass and/or an inline coal mill with a separate stack
associated with a kiln, the main exhaust and alkali bypass and/or inline coal
mill shall be tested simultaneously and the combined emission rate of PM
from the kiln and alkali bypass and/or inline coal mill shall be computed for
each run as specified in 40 CFR 63.1349(b)(1)(viii)

(40 CFR 63.1348(a)(1), 40 CFR 63.1349(b)(1), DAQE-AN100070027-20)

(b) Continuous Monitoring Requirements:

The permittee shall demonstrate compliance with the emissions standards and
operating limits by using the performance test methods and procedures in 40 CFR
63.1350 and 63.8 for each affected source.

The permittee shall monitor and collect data according to 40 CFR 63.1350 and the
site-specific monitoring plan required by 40 CFR 63.1350(p).

Except for periods of startup and shutdown, monitoring system malfunctions,
repairs associated with monitoring system malfunctions, and required monitoring
system quality assurance or quality control activities (including, as applicable,
calibration checks and required zero and span adjustments), the permittee shall
operate the monitoring system and collect data at all required intervals at all times
the affected source is operating.

The permittee shall not use data recorded during monitoring system startup,
shutdown or malfunctions or repairs associated with monitoring system
48
malfunctions in calculations used to report emissions or operating levels. A
monitoring system malfunction is any sudden, infrequent, not reasonably
preventable failure of the monitoring system to provide valid data. Monitoring
system failures that are caused in part by poor maintenance or careless operation
are not malfunctions. The permittee shall use all the data collected during all other
periods in assessing the operation of the control device and associated control
system.

The permittee shall use the following monitoring methods and procedures.

(i) The permittee shall use a PM CPMS to establish a site-specific operating
limit corresponding to the results of the performance test demonstrating
compliance with the PM limit. The permittee shall conduct a performance
test using Method 5 or Method 5I at appendix A-3 to 40 CFR part 60. The
permittee shall use the PM CPMS to demonstrate continuous compliance
with this operating limit. The permittee shall repeat the performance test
annually and reassess and adjust the site-specific operating limit in
accordance with the results of the performance test using the procedures in
II.B.6.j.1(a)(i) through (vi). The test shall also be repeated if the permittee
changes the analytical range of the instrument, or replaces the instrument
itself or any principle analytical component of the instrument that would
alter the relationship of output signal to in-stack PM concentration.

(ii) To determine continuous compliance, the permittee shall use the PM CPMS
output data for all periods when the process is operating and the PM CPMS
is not out-of-control. The permittee shall demonstrate continuous
compliance by using all quality-assured hourly average data collected by
the PM CPMS for all operating hours to calculate the arithmetic average
operating parameter in units of the operating limit (milliamps or the digital
equivalent) on a 30 operating day rolling average basis, updated at the end
of each new kiln operating day.

(iii) For any exceedance of the 30 process operating day PM CPMS average
value from the established operating parameter limit, the permittee shall:

a. Within 48 hours of the exceedance, visually inspect the APCD[;

b. If inspection of the APCD identifies the cause of the exceedance, take
corrective action as soon as possible and return the PM CPMS
measurement to within the established value; and

c. Within 30 days of the exceedance or at the time of the annual
compliance test, whichever comes first, conduct a PM emissions
compliance test to determine compliance with the PM emissions limit
and to verify or re-establish the PM CPMS operating limit within 45
days. The permittee is not required to conduct additional testing for any
exceedances that occur between the time of the original exceedance and
the PM emissions compliance test required under this paragraph.

(iv) PM CPMS exceedances leading to more than four required performance
tests in a 12-month process operating period (rolling monthly) constitute a
presumptive violation of 40 CFR 63 Subpart LLL.
49

(v) The permittee shall determine hourly clinker production by one of two
methods:

a. Install, calibrate, maintain, and operate a permanent weigh scale system
to measure and record weight rates in tons-mass per hour of the amount
of clinker produced. The system of measuring hourly clinker
production must be maintained within +/- 5 percent accuracy, or

b. Install, calibrate, maintain, and operate a permanent weigh scale system
to measure and record weight rates in tons-mass per hour of the amount
of feed to the kiln. The system of measuring feed must be maintained
within +/- 5 percent accuracy. Calculate the hourly clinker production
rate using a kiln-specific feed to clinker ratio based on reconciled
clinker production determined for accounting purposes and recorded
feed rates. Update this ratio monthly. Note that if this ratio changes at
clinker reconciliation, the permittee shall use the new ratio going
forward, but does not have to retroactively change clinker production
rates previously estimated.

(vi) During each quarter of source operation, the permittee shall determine,
record, and maintain a record of the ongoing accuracy of the system of
measuring hourly clinker production (or feed mass flow).

(vii) If clinker production is measured directly, record the daily clinker
production rates; if the kiln feed rates are measured and the clinker
production calculated, record the hourly kiln feed and clinker production
rates.

(viii) The permittee shall develop an emissions monitoring plan in accordance
with 40 CFR 63.1350(p)(1) through (4).

Performance tests for PM shall be repeated every 12 months. Performance
tests required every 12 months shall be completed no more than 13 calendar
months after the previous performance test.

(40 CFR 63.1348(b)(1), (2), 40 CFR 63.1349(c), 40 CFR 63.1350(b), (d))

The permittee may undertake a change in operations as specified in 40 CFR 63.1348(c).

The permittee shall conduct performance tests under conditions based on representative
performance of the affected source for the period being tested. The permittee shall make
available, upon request, such records as may be necessary to determine the conditions of
performance tests. (40 CFR 63.1349(e))

The permittee shall demonstrate compliance on a continuous basis by meeting the
requirements of this monitoring condition. For each existing unit that is equipped with a
CMS, the permittee shall maintain the average emissions or the operating parameter values
within the operating parameter limits established through performance tests. Any instance
where the permittee fails to comply with the continuous monitoring requirements of this
section is a violation. (40 CFR 63.1350(a)).

[Origin: 40 CFR 63 Subpart LLL]. [40 CFR 63.1343(a), 40 CFR 63.1343(b)(1)]

II.B.6.k.1 Monitoring:

The permittee shall demonstrate compliance with the emissions standards and operating
limits by using the test methods and procedures in 40 CFR 63.1349, R307-170, and 40
CFR 63.7. (40 CFR 63.1348(a))

The permittee shall demonstrate compliance with the mercury standards by using the
performance test methods and procedures in paragraph (a). The permittee shall
51
demonstrate compliance by operating a mercury CEMS or a sorbent trap based CEMS.

In calculating a 30 operating day emissions value using an integrating sorbent trap CEMS,
the permittee shall follow the procedures specified in 40 CFR 63.1348(a)(5)(i) and (ii).

(a) The permittee shall operate a mercury CEMS or a sorbent trap monitoring system
in accordance with the following requirements. If a mercury CEMS or a sorbent
trap monitoring system is used, the permittee shall install, operate, calibrate, and
maintain an instrument for continuously measuring and recording the exhaust gas
flow rate to the atmosphere according to the requirements in paragraph (vi). The
emission rate shall be calculated as specified in 40 CFR 63.1349(b)(5)(ii).

(i) The permittee shall install and operate a mercury continuous emissions
monitoring system (Hg CEMS) in accordance with Performance Specification
12A (PS 12A) of appendix B to 40 CFR part 60 or an integrated sorbent trap
monitoring system in accordance with Performance Specification 12B (PS
12B) of appendix B to 40 CFR part 60. The permittee shall monitor mercury
continuously according to paragraphs (ii) through (vi). The permittee shall
also develop an emissions monitoring plan in accordance with 40 CFR
63.1350(p)(1) through (4).

(ii) The permittee shall use a span value for any Hg CEMS that represents the
mercury concentration corresponding to approximately two times the
emissions standard and may be rounded up to the nearest multiple of 5
micrograms/m3 of total mercury or higher level if necessary to include Hg
concentrations which may occur (excluding concentrations during in-line raw
'mill off' operation). As specified in PS 12A, Section 6.1.1, the data recorder
output range must include the full range of expected Hg concentration values
which would include those expected during 'mill off' conditions. Engineering
judgments made and calculations used to determine the corresponding span
concentration from the emission standard shall be documented in the site-
specific monitoring plan and associated records.

(iii) The permittee shall quality assure data measured above the span value as
specified in 40 CFR 63.1350(k)(2) or other EPA-approved alternative, as
acceptable to the Director.

(iv) The permittee shall operate and maintain each Hg CEMS or an integrated
sorbent trap monitoring system according to the quality assurance
requirements in Procedure 5 of appendix F to 40 CFR part 60. During the
RATA of integrated sorbent trap monitoring systems required under
Procedure 5, the permittee may apply the appropriate exception for sorbent
trap section 2 breakthrough in 40 CFR 63.1350(k)(3).

(v) Relative accuracy testing of mercury monitoring systems under PS 12A, PS
12B, or Procedure 5 shall be conducted at normal operating conditions. The
testing shall occur with the raw mill on.

(vi) If a Hg CEMS or an integrated sorbent trap monitoring system is used, the
permittee shall install, operate, calibrate, and maintain instruments for
continuously measuring and recording the exhaust gas flow rate to the
atmosphere according to the requirements in 40 CFR 63.1350(n)(1) through
52
(10) to allow determination of the pollutant mass emission rate from sources
subject to an emission limitation that has a pounds per ton of clinker unit and
that is required to be monitored by a CEMS.

(vii) If an integrated sorbent trap monitoring system conforming to PS 12B is
operated, the permittee may use a monitoring period at least 24 hours but no
longer than 168 hours in length. The permittee should use a monitoring period
that is a multiple of 24 hours (except during relative accuracy testing as
allowed in PS 12B).

(40 CFR 63.1348(a)(5), 40 CFR 63.1349(b)(5), 40 CFR 63.1350(k), (n))

(b) Continuous Monitoring Requirements:

The permittee shall demonstrate compliance with the emissions standards and
operating limits by using the performance test methods and procedures in 40 CFR
63.1350 and 63.8 for each affected source.

The permittee shall monitor and collect data according to 40 CFR 63.1350, R307-
170, and the site-specific monitoring plan required by 40 CFR 63.1350(p).

Except for periods of startup and shutdown, monitoring system malfunctions,
repairs associated with monitoring system malfunctions, and required monitoring
system quality assurance or quality control activities (including, as applicable,
calibration checks and required zero and span adjustments), the permittee shall
operate the monitoring system and collect data at all required intervals at all times
the affected source is operating.

The permittee shall not use data recorded during monitoring system startup,
shutdown or malfunctions, or repairs associated with monitoring system
malfunctions in calculations used to report emissions or operating levels. A
monitoring system malfunction is any sudden, infrequent, not reasonably
preventable failure of the monitoring system to provide valid data. Monitoring
system failures that are caused in part by poor maintenance or careless operation
are not malfunctions. The permittee shall use all the data collected during all other
periods in assessing the operation of the control device and associated control
system.

(i) The permittee shall demonstrate compliance using the monitoring methods
and procedures in II.B.6.k.1.(a)(i)-(vii). If an integrated sorbent trap
monitoring system is used to determine ongoing compliance, use the
procedures described in 40 CFR 63.1348(a)(5) to assign hourly mercury
concentration values and to calculate rolling 30 operating day emissions
rates. Since the permittee assigns the mercury concentration measured with
the sorbent trap to each relevant hour respectively for each operating day of
the integrated period, the permittee may schedule the sorbent trap change
periods to any time of the day (i.e., the sorbent trap replacement need not be
scheduled at 12:00 midnight nor must the sorbent trap replacements occur
only at integral 24-hour intervals).

(ii) Mercury shall be measured either upstream of the coal mill or in the coal
mill stack.
53

(iii) The permittee shall determine hourly clinker production by one of two
methods:

a. Install, calibrate, maintain, and operate a permanent weigh scale system
to measure and record weight rates in tons-mass per hour of the amount
of clinker produced. The system of measuring hourly clinker
production must be maintained within +/- 5 percent accuracy, or

b. Install, calibrate, maintain, and operate a permanent weigh scale system
to measure and record weight rates in tons-mass per hour of the amount
of feed to the kiln. The system of measuring feed must be maintained
within +/- 5 percent accuracy. Calculate the hourly clinker production
rate using a kiln-specific feed to clinker ratio based on reconciled
clinker production determined for accounting purposes and recorded
feed rates. Update this ratio monthly. Note that if this ratio changes at
clinker reconciliation, the permittee shall use the new ratio going
forward, but does not have to retroactively change clinker production
rates previously estimated.

(iv) During each quarter of source operation, the permittee shall determine,
record, and maintain a record of the ongoing accuracy of the system of
measuring hourly clinker production (or feed mass flow).

(v) If clinker production is measured directly, record the daily clinker
production rates; if the kiln feed rates are measured and the clinker
production calculated, record the hourly kiln feed and clinker production
rates

(vi) The permittee shall develop an emissions monitoring plan in accordance
with 40 CFR 63.1350(p)(1) through (4)

((40 CFR 63.1348(b)(1), (7), 40 CFR 63.1350(d), (k))

The permittee may undertake a change in operations as specified in 40 CFR
63.1348(c).

The permittee shall conduct performance tests under conditions based on
representative performance of the affected source for the period being tested. The
permittee shall make available, upon request, such records as may be necessary to
determine the conditions of performance tests. (40 CFR 63.1349(e))

The permittee shall demonstrate compliance on a continuous basis by meeting the
requirements of this monitoring condition. For each existing unit that is equipped
with a CMS, the permittee shall maintain the average emissions or the operating
parameter values within the operating parameter limits established through
performance tests. Any instance where the permittee fails to comply with the
continuous monitoring requirements of this section is a violation. (40 CFR
63.1350(a)).

II.B.6.k.2 Recordkeeping:

54
Records shall be maintained in accordance with 40 CFR 63.1355, Table 1 to 40 CFR 63
Subpart LLL-Applicability of General Provisions, R307-170, and Provision I.S.1 of this
permit.

II.B.6.k.3 Reporting:

In addition to the reporting requirements in Section I of this permit, the permittee shall
report the results of the performance test before the close of business on the 60th day
following the completion of the performance test. The permittee shall also comply with the
following

(a) Performance test results shall be documented in complete test reports in
accordance with 40 CFR 63.1349(a).

(b) The permittee shall comply with the reporting provisions of 40 CFR 63.1354(a)
and (b) as applicable.

(c) The permittee shall comply with the notification provisions of 40 CFR 63.1353.

Reports shall be submitted quarterly, as outlined in R307-170, Continuous Emission
Monitoring Program. The reports are considered prompt notification of permit deviation
required in Provision I.S.2.c of this permit, if all information required by Provision I.S.2.c
is included in the report.

Status: In compliance – The CEMs have been installed and operated. CEM requirements are
evaluated by DAQ’s CEM specialist. This includes reviewing Relative Accuracy Test
Audits (RATA) and quarterly State Electronic Data Reports. See memorandums in
the source file.

II.B.6.l Condition:

Emissions of total hydrocarbon (THC) shall be no greater than 24 ppmvd, on a dry basis,
measured as propane, corrected to 7 percent oxygen, based on a rolling 30-day average
during normal operation. The 30-day period means all operating hours within 30
consecutive kiln operating days excluding periods of startup and shutdown.

Any source subject to the 24 ppmvd THC limit may elect to meet an alternative limit of 12
ppmvd for total organic HAP.
[Origin: 40 CFR 63 Subpart LLL]. [40 CFR 63.1343(a), 40 CFR 63.1343(b)(1)]

II.B.6.l.1 Monitoring:

The permittee shall demonstrate compliance with the emissions standards and operating
limits by using the test methods and procedures in 40 CFR 63.1349, R307-170, and 40
CFR 63.7. (40 CFR 63.1348(a))

(a) THC Compliance: The permittee shall demonstrate compliance with the THC
emissions standards by using the following performance test methods and
procedures. The permittee shall operate a CEMS in accordance with the following
requirements. For the purposes of conducting the accuracy and quality assurance
evaluations for CEMS, the THC span value (as propane) is 50 to 60 ppmvw and
55
the reference method (RM) is Method 25A of 40 CFR 60, Appendix A. THC shall
be measured either upstream of the coal mill or the coal mill stack.

(i) The permittee shall install, operate, and maintain a THC continuous
emission monitoring system in accordance with Performance Specification 8
or Performance Specification 8A of appendix B to 40 CFR 60 and comply
with all of the requirements for continuous monitoring systems found in the
general provisions, subpart A of 40 CFR 63. The permittee shall operate and
maintain each CEMS according to the quality assurance requirements in
Procedure 1 of appendix F in 40 CFR 60. For THC continuous emission
monitoring systems certified under Performance Specification 8A, conduct
the relative accuracy test audits required under Procedure 1 in accordance
with Performance Specification 8, Sections 8 and 11 using Method 25A in
appendix A to 40 CFR part 60 as the reference method; the relative accuracy
must meet the criteria of Performance Specification 8, Section 13.2.

(ii) Performance tests on alkali bypass and coal mill stacks shall be conducted
using Method 25A in appendix A to 40 CFR part 60 and repeated every 30
months.

(b) Total Organic HAP Emission Tests: If the permittee elects to demonstrate
compliance with the total organic HAP emissions limit in lieu of the THC
emissions limit, the permittee shall demonstrate compliance with the total organic
HAP emissions standards by using the following performance test methods and
procedures, instead of conducting the compliance test specified under THC
Compliance. The time weighted average total organic HAP concentration
measured during the separate initial performance test specified by 40 CFR
63.1349(b)(7) shall be used to determine initial compliance. The time weighted
average THC concentration measured during the initial performance test specified
by paragraph (a) shall be used to determine the site-specific THC limit. Using the
fraction of time the inline kiln/raw mill is on and the fraction of time that the
inline kiln/raw mill is off, the permittee shall calculate this limit as a time
weighted average of the THC levels measured during raw mill on and raw mill off
testing using one of the two approaches in (vii) or (viii) depending on the level of
organic HAP measured during the compliance test.

(i) The permittee shall use Method 320 of 40 CFR 63 Appendix A, Method 18
of 40 CFR 60 Appendix A, ASTM D6348-03 or a combination to
determine emissions of total organic HAP. Each performance test shall
consist of three separate runs under the conditions that exist when the
affected source is operating at representative performance conditions in
accordance with 40 CFR 63.7(e). Each run shall be conducted for at least 1
hour

(ii) At the same time that the permittee is conducting the performance test for
total organic HAP, the permittee shall also determine a site-specific THC
emissions limit by operating a THC CEMS in accordance with the
requirements of paragraph (A). The duration of the performance test shall
be at least 3 hours and the average THC concentration (as calculated from
the recorded output) during the 3-hour test shall be calculated. The
permittee shall establish the THC operating limit and determine compliance
with it according to paragraphs (vii) and (viii). It is permissible to extend
56
the testing time of the organic HAP performance test if the permittee
believes extended testing is required to adequately capture organic HAP
and/or THC variability over time

a. The permittee shall continuously monitor THC according to paragraph (a)
or in accordance with Performance Specification 8 or 8A of appendix B to
40 CFR 60 and comply with all of the requirements for continuous
monitoring systems found in the general provisions, subpart A of 40 CFR
63. The permittee shall operate and maintain each CEMS according to the
quality assurance requirements in Procedure 1 of appendix F in 40 CFR
part 60.

(iii) The permittee shall use the fraction of time the raw mill is on and the
fraction of time that the raw mill is off and calculate this limit as a weighted
average of the THC levels measured during three raw mill on and three raw
mill off tests.

(iv) If the organic HAP emissions are below 75 percent of the organic HAP
standard and the permittee determines the operating limit with paragraph
(vi) the THC CEMS shall be calibrated and operated on a measurement
scale no greater than 180 ppmvw, as carbon, or 60 ppmvw as propane.

(v) The THC CEMS measurement scale shall be capable of reading THC
concentrations from zero to a level equivalent to two times the highest THC
emissions average determined during the performance test, including mill
on or mill off operation. Note: This may require the use of a dual range
instrument to meet this requirement and paragraph (iv).

(vi) The operating limit shall be determined as specified in paragraphs (vii) and
(viii). If the organic HAP performance test demonstrates average organic
HAP emission levels are below 75 percent of the emission limit (9 ppmv)
the permittee shall use the average THC value recorded during the organic
HAP performance test, and the average total organic HAP result of the
performance test to establish the operating limit. If the organic HAP
compliance test results demonstrate that average organic HAP emission
levels are at or above 75 percent of the emission limit, the operating limit is
established as the average THC value recorded during the organic HAP
performance test. The permittee shall establish a new operating limit after
each performance test. The permittee shall repeat the performance test no
later than 30 months following the last performance test and reassess and
adjust the site-specific operating limit in accordance with the results of the
performance test.

(vii) If the average organic HAP results for the three Method 18 and/or Method
320 performance test runs are below 75 percent of the organic HAP
emission limit, the permittee shall calculate an operating limit by
establishing a relationship of THC CEMS signal to the organic HAP
concentration using the average THC CEMS value corresponding to the
three organic HAP compliance test runs and the average organic HAP total
concentration from the Method 18 and/or Method 320 performance test
runs with the procedures in (A) and (B).

57
a. Determine the THC CEMS average values in ppmvw, and the average of
the corresponding three total organic HAP compliance test runs, as
specified in 40 CFR 63.1349(b)(7)(viii)(A)

b. Use the three run average THC CEMS value, and the three run average
organic HAP concentration from the three Method 18 and/or Method 320
compliance tests to determine the operating limit in units of ppmvw THC,
as propane, as specified in 40 CFR 63.1349(b)(7)(viii)(B).

(viii) If the average of the three organic HAP performance test runs is at or above
75 percent of the organic HAP emission limit, the permittee shall determine
the operating limit as specified in 40 CFR 63.1349(b)(7)(ix) by averaging
the THC CEMS output values corresponding to the three organic HAP
performance test runs that demonstrate compliance with the emission limit.
If the new THC CEMS value is below the current operating limit, the
permittee may opt to retain the current operating limit, but must still submit
all performance test and THC CEMS data according to the reporting
requirements

(ix) The permittee shall conduct separate performance tests while the raw mill is
operating ('mill on') and while the raw mill is not operating ('mill off').
Using the fraction of time the raw mill is on and the fraction of time that the
raw mill is off, calculate this limit as a weighted average of the THC levels
measured during raw mill on and raw mill off compliance testing as
specified in 40 CFR 63.1349(b)(7)(x).

(x) To determine continuous compliance with the THC operating limit, the
permittee shall record the THC CEMS output data for all periods when the
process is operating and the THC CEMS is not out-of-control. The
permittee shall demonstrate continuous compliance by using all quality-
assured hourly average data collected by the THC CEMS for all operating
hours to calculate the arithmetic average operating parameter in units of the
operating limit (ppmvw) on a 30 operating day rolling average basis,
updated at the end of each new kiln operating day. The permittee shall
determine the 30 kiln operating day average as specified in 40 CFR
63.1349(b)(7)(xi)

(xi) Use EPA Method 18 or Method 320 of appendix A to 40 CFR part 60 to
determine organic HAP emissions. For each performance test, conduct at
least three separate runs under the conditions that exist when the affected
source is operating at the level reasonably expected to occur. The permittee
shall conduct three separate test runs with the raw mill on, and three
separate runs under the conditions that exist when the affected source is
operating at the level reasonably expected to occur with the mill off.
Conduct each Method 18 test run to collect a minimum target sample
equivalent to three times the method detection limit. Calculate the average
of the results from three runs to determine compliance

(xii) If the THC level exceeds the site-specific THC emissions limit by 10
percent or more, the permittee shall

58
a. As soon as possible but no later than 30 days after the exceedance,
conduct an inspection and take corrective action to return the THC CEMS
measurements to within the established value; and

b. Within 90 days of the exceedance or at the time of the 30 month
compliance test, whichever comes first, conduct another performance test
to determine compliance with the organic HAP limit and to verify or re-
establish the site-specific THC emissions limit.

(c) The permittee shall develop an emission monitoring plan and comply with the
monitoring requirements as specified in 40 CFR 63.1350(m)(1) through (4) and 40
CFR 63.1350(p)(1) through (4).

associated with monitoring system malfunctions, and required monitoring system quality
assurance or quality control activities (including, as applicable, calibration checks and
required zero and span adjustments), the permittee shall operate the monitoring system and
collect data at all required intervals at all times the affected source is operating.

The permittee shall not use data recorded during monitoring system startup, shutdown or
malfunctions, or repairs associated with monitoring system malfunctions in calculations
used to report emissions or operating levels. A monitoring system malfunction is any
sudden, infrequent, not reasonably preventable failure of the monitoring system to provide
valid data. Monitoring system failures that are caused in part by poor maintenance or
careless operation are not malfunctions. The permittee shall use all the data collected
during all other periods in assessing the operation of the control device and associated
control system.

The permittee shall demonstrate compliance using the monitoring methods and procedures
in paragraphs (a)(i) and (ii), (b)(ii)(A), and (c). THC shall be measured either upstream of

II.B.7.c.1 Monitoring:

The permittee shall demonstrate compliance with the emissions standards and operating
limits by using the test methods and procedures in 40 CFR 63.1349 and 40 CFR 63.7.
(40 CFR 63.1348(a))

(a) The permittee shall demonstrate compliance with the PM emissions standards by
using the following test methods and procedures. Initial compliance shall be
demonstrated by conducting a performance test using Method 5 or Method 5I in
40 CFR 60 Appendix A-3. The permittee shall also monitor continuous
performance through use of a PM continuous parametric monitoring system (PM
CPMS).

(i) The permittee shall establish a site-specific operating limit for the PM CPMS.
The permittee shall use the PM CPMS to demonstrate continuous compliance
with the operating limit.

a. The PM CPMS shall provide a 4-20 milliamp or digital signal output and
the establishment of its relationship to manual reference method
measurements shall be determined in units of milliamps or the monitor's
digital equivalent.

b. The PM CPMS operating range shall be capable of reading PM
concentrations from zero to a level equivalent to three times the allowable
emission limit. If the PM CPMS is an auto-ranging instrument capable of
multiple scales, the primary range of the instrument shall be capable of
reading PM concentration from zero to a level equivalent to three times
the allowable emission limit.

c. During the initial performance test or any such subsequent performance
test that demonstrates compliance with the PM limit, the permittee shall
record and average all milliamp or digital output values from the PM
CPMS for the periods corresponding to the compliance test runs (e.g.,
average all the PM CPMS output values for three corresponding Method
5I test runs).

(ii) The permittee shall determine the operating limit as specified in paragraphs
(iii) through (iv). If the PM performance test demonstrates PM emission
levels to be below 75 percent of the emission limit the permittee shall use the
average PM CPMS value recorded during the PM compliance test, the
milliamp or digital equivalent of zero output from the PM CPMS, and the
average PM result of the compliance test to establish the operating limit. If
the PM compliance test demonstrates PM emission levels to be at or above 75
percent of the emission limit the permittee shall use the average PM CPMS
value recorded during the PM compliance test to establish the operating limit.
The permittee shall verify an existing or establish a new operating limit after
each repeated performance test. The permittee shall repeat the performance
test at least annually and reassess and adjust the site-specific operating limit
in accordance with the results of the performance test

(iii) If the average of the three Method 5 or 5I compliance test runs is below 75
percent of the PM emission limit, the permittee shall calculate an operating
66
limit by establishing a relationship of PM CPMS signal to PM concentration
using the PM CPMS instrument zero, the average PM CPMS values
corresponding to the three compliance test runs, and the average PM
concentration from the Method 5 or 5I compliance test with the procedures in
(iii)(A) through (D).

a. Determine the PM CPMS instrument zero output with one of the
procedures specified in 40 CFR 63.1349(b)(1)(iii)(A)

b. Determine the PM CPMS instrument average in milliamps or digital
equivalent, and the average of the corresponding three PM compliance test
runs, as specified in 40 CFR 63.1349(b)(1)(iii)(B).

c. With the instrument zero expressed in milliamps or a digital value, the
three run average PM CPMS milliamp or digital signal value, and the
three run PM compliance test average, determine a relationship of lb/ton-
clinker per milliamp or digital signal value as specified in 40 CFR
63.1349(b)(1)(iii)(C).

d. Determine the source specific 30-day rolling average operating limit using
the lb/ton-clinker per milliamp or digital signal value as specified in 40
CFR 63.1349(b)(1)(iii)(D). This sets the operating limit at the PM CPMS
output value corresponding to 75 percent of the emission limit

(iv) If the average of the three PM compliance test runs is at or above 75 percent
of the PM emission limit the permittee shall determine the operating limit by
averaging the PM CPMS milliamp or digital equivalent output corresponding
to the three PM performance test runs that demonstrate compliance with the
emission limit as specified in 40 CFR 63.1349(b)(1)(iv).

(v) To determine continuous operating compliance, the permittee shall record the
PM CPMS output data for all periods when the process is operating, and use
all the PM CPMS data for calculations when the source is not out-of-control.
The permittee shall demonstrate continuous compliance by using all quality-
assured hourly average data collected by the PM CPMS for all operating
hours to calculate the arithmetic average operating parameter in units of the
operating limit (milliamps or the digital equivalent) on a 30 operating day
rolling average basis, updated at the end of each new kiln operating day. The
permittee shall determine the 30 kiln operating day average as specified in 40
CFR 63.1349(b)(1)(v).

(vi) For each performance test, the permittee shall conduct at least three separate
test runs each while the mill is on and the mill is off under the conditions that
exist when the affected source is operating at the level reasonably expected to
occur. Conduct each test run to collect a minimum sample volume of 1 dscm
for determining compliance with an existing source limit. Calculate the time
weighted average of the results from three consecutive runs, including
applicable sources, to determine compliance. The permittee need not
determine the particulate matter collected in the impingers ('back half') of the
Method 5 or Method 5I particulate sampling train to demonstrate compliance
with the PM standards

67
(vii) The permittee shall demonstrate initial compliance by conducting separate
performance tests while the raw mill is under normal operating conditions
and while the raw mill is not operating, and calculate the time weighted
average emissions. The operating limit shall then be determined using 40
CFR 63.1349(b)(1)(i)

(40 CFR 63.1348(a)(1), 40 CFR 63.1349(b)(1))

(b) Continuous Monitoring Requirements
The permittee shall demonstrate compliance with the emissions standards and
operating limits by using the performance test methods and procedures in 40 CFR
63.1350 and 63.8 for each affected source.

The permittee shall monitor and collect data according to 40 CFR 63.1350 and the
site-specific monitoring plan required by 40 CFR 63.1350(p).

Except for periods of startup and shutdown, monitoring system malfunctions,
repairs associated with monitoring system malfunctions, and required monitoring
system quality assurance or quality control activities (including, as applicable,
calibration checks and required zero and span adjustments), the permittee shall
operate the monitoring system and collect data at all required intervals at all times
the affected source is operating.

The permittee shall not use data recorded during monitoring system startup,
shutdown or malfunctions, or repairs associated with monitoring system
malfunctions in calculations used to report emissions or operating levels. A
monitoring system malfunction is any sudden, infrequent, not reasonably
preventable failure of the monitoring system to provide valid data. Monitoring
system failures that are caused in part by poor maintenance or careless operation
are not malfunctions. The permittee shall use all the data collected during all other
periods in assessing the operation of the control device and associated control
system.

The permittee shall use the following monitoring methods and procedures.

(i) The permittee shall use a PM CPMS to establish a site-specific operating
limit corresponding to the results of the performance test demonstrating
compliance with the PM limit. The permittee shall conduct a performance
test using Method 5 or Method 5I at appendix A-3 to 40 CFR part 60. The
permittee shall use the PM CPMS to demonstrate continuous compliance
with this operating limit. The permittee shall repeat the performance test
annually and reassess and adjust the site-specific operating limit in
accordance with the results of the performance test using the procedures in
II.B.7.c.1(a)(i) through (vi). The test shall also be repeated if the permittee
changes the analytical range of the instrument, or replaces the instrument
itself or any principle analytical component of the instrument that would
alter the relationship of output signal to in-stack PM concentration.

(ii) To determine continuous compliance, the permittee shall use the PM CPMS
output data for all periods when the process is operating and the PM CPMS
is not out-of-control. The permittee shall demonstrate continuous
68
compliance by using all quality-assured hourly average data collected by the
PM CPMS for all operating hours to calculate the arithmetic average
operating parameter in units of the operating limit (milliamps) on a 30
operating day rolling average basis, updated at the end of each new kiln
operating day.

(iii) For any exceedance of the 30 process operating day PM CPMS average
value from the established operating parameter limit, the permittee shall:

a. Within 48 hours of the exceedance, visually inspect the APCD;

b. If inspection of the APCD identifies the cause of the exceedance, take
corrective action as soon as possible and return the PM CPMS
measurement to within the established value; and

c. Within 30 days of the exceedance or at the time of the annual
compliance test, whichever comes first, conduct a PM emissions
compliance test to determine compliance with the PM emissions limit
and to verify or re-establish the PM CPMS operating limit within 45
days. The permittee is not required to conduct additional testing for any
exceedances that occur between the time of the original exceedance and
the PM emissions compliance test required under this paragraph.
(iv) PM CPMS exceedances leading to more than four required performance
tests in a 12-month process operating period (rolling monthly) constitute a
presumptive violation of 40 CFR 63 Subpart LLL

(v) The permittee shall determine hourly clinker production by one of two
methods:

a. Install, calibrate, maintain, and operate a permanent weigh scale system
to measure and record weight rates in tons-mass per hour of the amount
of clinker produced. The system of measuring hourly clinker production
must be maintained within +/- 5 percent accuracy, or

b. Install, calibrate, maintain, and operate a permanent weigh scale system
to measure and record weight rates in tons-mass per hour of the amount
of feed to the kiln. The system of measuring feed must be maintained
within +/- 5 percent accuracy. Calculate the hourly clinker production
rate using a kiln-specific feed to clinker ratio based on reconciled
clinker production determined for accounting purposes and recorded
feed rates. Update this ratio monthly. Note that if this ratio changes at
clinker reconciliation, the permittee shall use the new ratio going
forward, but does not have to retroactively change clinker production
rates previously estimated.

(vi) During each quarter of source operation, the permittee shall determine,
record, and maintain a record of the ongoing accuracy of the system of
measuring hourly clinker production (or feed mass flow).

(vii) If clinker production is measured directly, record the daily clinker
production rates; if the kiln feed rates are measured and the clinker
69
production calculated, record the hourly kiln feed and clinker production
rates.

(viii) The permittee shall develop an emissions monitoring plan in accordance
with 40 CFR 63.1350(p)(1) through (4)

Performance tests for PM shall be repeated every 12 months. Performance tests required
every 12 months shall be completed no more than 13 calendar months after the previous
performance test

(40 CFR 63.1348(b)(1), (2), 40 CFR 63.1349(c), 40 CFR 63.1350(b), (d))

The permittee may undertake a change in operations as specified in 40 CFR 63.1348(c).

performance of the affected source for the period being tested. The permittee shall make
available, upon request, such records as may be necessary to determine the conditions of
performance tests. (40 CFR 63.1349(e))

The permittee shall demonstrate compliance on a continuous basis by meeting the
requirements of this monitoring condition. For each existing unit that is equipped with a
CMS, the permittee shall maintain the average emissions or the operating parameter values
within the operating parameter limits established through performance tests. Any instance
where the permittee fails to comply with the continuous monitoring requirements of this
section is a violation. (40 CFR 63.1350(a)).

II.B.7.c.2 Recordkeeping:

Records and results of monitoring shall be maintained in accordance with 40 CFR
63.1355, Table 1 to 40 CFR 63 Subpart LLL-Applicability of General Provisions, and

I wanted to update you on the status of the SNCR at the Holcim Devil's Slide Cement Plant. We have not yet started
construction on the SNCR project for devil's slide as laid out in our Title V permit II.B.6.o, I realize this A.O. is invalid.
We are awaiting a new plant manager in order to move forward with this project (plant manager position is currently
vacant), by the time we decide on the direction we will have to go through a separate approval process.
We have had some previous quotes that we will be having updated as well as looking at other alternatives and technology
that could provide the same benefit by different means.

Joe,
Just catching up from some time off, sorry I missed you.
I walked them all in on Friday 1 DEC, gave them to the DAQ Desk after being buzzed in (I made sure it was DAQ office).
Have you received them yet? They were all contained in a manilla envelope I believe.
I can forward you some scanned versions if needed.

Joe,
For A/C and recycling we utilize MSS as needed, PO 4501752183, MSS 4/112023 is the most recent one I can find
(attached).
In the past e have used Robert Brierly (onsite employee) but I am trying to ascertain his certifications and recency.
