National Emission Standards for Hazardous Air Pollutants for the
Portland Cement Manufacturing Industry and Standards of Performance for
Portland Cement Plants

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final amendments.

-----------------------------------------------------------------------

SUMMARY: This action finalizes amendments to the National Emission
Standards for Hazardous Air Pollutants (NESHAP) for the Portland Cement
Manufacturing Industry and Standards of Performance for Portland Cement
Plants. On February 12, 2013, the Environmental Protection Agency (EPA)
finalized amendments to the NESHAP and the new source performance
standards (NSPS) for the Portland cement industry. Subsequently, the
EPA became aware of certain minor technical errors in those amendments,
and thus issued a proposal to correct these errors on November 19, 2014
(79 FR 68821). The EPA received 3 comments on the proposal. In response
to the comments received and to complete technical corrections, the EPA
is now issuing final amendments. In addition, consistent with the U.S.
Court of Appeals to the DC Circuit's vacatur of the affirmative defense
provisions in the final rule, this action removes those provisions.
These amendments do not affect the pollution reduction or costs
associated with these standards.

DATES: This final rule is effective on July 27, 2015.

II. General Information

A. Executive Summary

1. Purpose of This Regulatory Action
    The purpose of this action is to finalize amendments to the 40 CFR
part 60, and part 63, subparts F and LLL, respectively. In 2010, the
EPA established the NESHAP for the Portland Cement source category. (75
FR 54970, September 9, 2010). Specifically, the EPA established
emission standards for mercury (Hg), hydrogen chloride (HCl), total
hydrocarbons (THC) (or in the alternative, organic hazardous air
pollutants (oHAP)), and particulate matter (PM). These standards,
established pursuant to section 112(d) of the Clean Air Act (CAA),
reflected performance of maximum available control technology.
Following court remand, Portland Cement Ass'n v. EPA, 665 F. 3d 177
(D.C. Cir. 2011), the EPA amended some of these standards in 2013, and
established a new compliance date of September 9, 2015, for the

amended standards. (78 FR 10006, Feb. 12, 2013). All of these actions
were upheld by the U.S. Court of Appeals for the District of Columbia
Circuit. Natural Resources Defense Council v. EPA, 749 F. 3d 1055 (D.C.
Cir. 2014). The Court, however, vacated a provision of the rule
establishing an affirmative defense when violations of the standards
occurred because of malfunctions. 749 F. 3d at 1063-64. In light of the
Court's vacatur, the regulatory provisions establishing the affirmative
defense are null and void. Thus, the EPA is removing the affirmative
defense regulatory text (40 CFR 63.1344) as part of this final
technical corrections rule.
    The EPA also adopted standards of performance for new Portland
cement sources as part of the same regulatory action establishing the
2010 NESHAP. (75 FR 54970, Sept. 9, 2010) and amended those standards
at the same time of the NESHAP amendments (see 78 FR 10006) (see also
Portland Cement Ass'n v. EPA, 665 F. 3d at 190-92 (upholding these
standards)). The EPA is finalizing certain technical changes to these
NSPS as part of this action.

requirements established by the final rule may not be challenged
separately in any civil or criminal proceedings brought by the EPA to
enforce the requirements.
    Section 307(d)(7)(B) of the CAA further provides that ``[o]nly an
objection to a rule or procedure which was raised with reasonable
specificity during the period for public comment (including any public
hearing) may be raised during judicial review.'' This section also
provides a mechanism for the EPA to convene a proceeding for
reconsideration, ``[i]f the person raising an objection can demonstrate
to the EPA that it was impracticable to raise such objection within
[the period for public comment] or if the grounds for such objection
arose after the period for public comment (but within the time
specified for judicial review) and if such objection is of central
relevance to the outcome of the rule.'' Any person seeking to make such
a demonstration should submit a Petition for Reconsideration to the
Office of the Administrator, U.S. EPA, WJC Building, 1200 Pennsylvania
Ave. NW., Mail Code 1101A, Washington, DC 20460, with a copy to both

III. Summary of Final Amendments

A. Corrections and Clarifications

    The EPA is finalizing certain clarifying changes and corrections to
the 2013 final rule. Specifically, these amendments will: (1) Clarify
the definition of rolling average, operating day and run average; (2)
restore the table of emission limits which apply until the September 9,
2015, compliance date; (3) correct equation 8 regarding sources with an
alkali bypass or inline coal mill that include a separate stack; (4)
provide a scaling alternative for sources that have a wet scrubber,
tray tower or dry scrubber relative to the HCl compliance
demonstration; (5) add a temperature parameter to the startup and
shutdown requirements; (6) clarify language related to span values for
both Hg and HCl measurements; and (7) correct inadvertent typographical
errors. The EPA is also finalizing corrections to certain inadvertent
inconsistencies in the final rule regulatory text, such as correction
of the compliance date for new sources and correction to the compliance
date regarding monitoring and recordkeeping requirements.
    In both the NSPS and the NESHAP, we are finalizing language to
clarify the existing definitions of Operating Day, Rolling Average and
Run Average to promote consistent and clear monitoring data recording
and emissions reporting. The clarifications below are in response to
industry questions and are not intended to change the meaning of the
final rule. In the final amendments, we clarify that ``Operating Day''
is any 24-hour period where clinker is produced. This clarification is
necessary to specify that during any day with both operations and
emissions, an emissions value or an average of emissions values
representing those operations is included in the 30-day rolling average
calculation. We also clarify that ``Rolling Average'' means a weighted
average of all monitoring data collected during a specified time period
divided by all production of clinker during those same hours of
operation, and, where applicable, a 30-day rolling average is comprised
of the average of all the hourly average concentrations over the
previous 30 operating days. This clarification is necessary to specify
the

way a long-term rolling average value is calculated such that different
facilities are not using different approaches to demonstrate compliance
with the rule. In addition, we clarify that ``Run Average'' means the
average of the recorded parameter values, not the 1-minute parameter
values, for a run.
    We are amending 40 CFR 63.1349(b)(8)(vii) to include a provision
describing performance testing requirements when a source demonstrates
compliance with the emissions standard using a continuous emissions
monitoring system (CEMS) for sulfur dioxide (SO2)
measurement and reporting.
    We are adding a scaling alternative whereby if a source uses a wet
scrubber, tray tower or dry scrubber, and where the test run average of
the three HCl compliance tests demonstrates compliance below 2.25 parts
per million by volume (ppmv) (which is 75 percent of the HCl emission
limit), the source may calculate an operating limit by establishing a
relationship of the average SO2 CEMS signal to the HCl
concentration (corrected to 7 percent oxygen). The operating limit
would be established at a point where the SO2 CEMS indicates
the source would be at 2.25 ppmv. Since the 2.25 ppmv is below the
actual limit of 3.0 ppmv, the source will continue to demonstrate
compliance with the HCl standard. Given the fact that SO2
controls preferentially remove HCl, an increase in SO2
emissions would not indicate an increase in HCl emissions as long as
some SO2 emissions reductions are occurring. Adding this
compliance flexibility should not result in any increase in HCl
emissions.
    We are also amending, under 40 CFR 63.1346(g)(3), language related
to the use of air pollution control devices (APCD). We had proposed
that all hazardous APCD be operating by the time the temperature to the
APCD reaches 300 [deg]F. However, during the comment period, the EPA
received further clarification on the temperature parameter. Commenters
noted that the temperature threshold during startup need only apply to
injection systems and not all APCD, and that the temperature reading
should occur at the PM control device inlet. Commenters also noted that
as soon as fuel is shut off during shutdown, gas flows can decrease to
the point where activated carbon and hydrated lime being injected can
fall out of the stream and accumulate in the duct work due to reduced
gas flows. In addition, lime affected by water vapor condensation
present during startup and shutdown conditions will cause the lime to
harden and reduce the efficiency for dust removal.\1\ Because of the
injection system operating restrictions with startup and shutdown,
revision of the startup and shutdown work practice is amended in the
final rule to clarify that the injection system may be shut off when
kiln feed is shut off. In addition to this revision regarding injection
systems, clarification that all control devices for HAP must be
operating during startup and shutdown has been included in the
regulatory text.
---------------------------------------------------------------------------

    \1\ These issues are further discussed in the docket, via
communication with John Holmes dated September 24, 2014.
---------------------------------------------------------------------------

    We are also finalizing measurement span criteria for HCl CEMS to
include better quality assurance/quality control (QA/QC) for
measurements of elevated HCl emissions that may result from ``mill
off'' operations. This slight increase in measurement span (from 5
parts per million (ppm) to 10 ppm) provides for an improved balance
between accurately quantifying measurements at low emissions levels
(the majority of operating time) and improving QA/QC for brief periods
of elevated emissions observed during ``mill off'' operation (the
majority of HCl mass emissions).
    In these final amendments, we remove 40 CFR 60.64(c)(2), which
applied when sources did not have valid 15-minute CEMS data. This
provision allowed for inclusion of the average emission rate from the
previous hour for which data were available. This provision was
inadvertently added to the final rule, but this substitution is not an
allowable action.
    We are also revising 40 CFR 63.1350(o) (Alternative Monitoring
Requirements Approval), because language in this section, which does
not allow an operator to apply for alternative THC monitoring, is now
obsolete. There is now alternative monitoring allowed in 40 CFR
63.1350(j) due to the 2013 final rule (see 78 FR 10015). A source that
emits a high amount of THC due to methane emissions, for example, can
follow the alternative oHAP monitoring requirements. For any other
reason that an alternative THC monitoring protocol is warranted, we
allow the source to submit an application to the Administrator subject
to the provisions of 40 CFR 63.1350(o)(1) through (6).

B. Affirmative Defense

    The EPA is removing a regulatory affirmative defense provision from
the rule. As explained above, removal of the affirmative defense merely
corrects the regulation to reflect that the provisions have no legal
effect in light of the court vacatur of the affirmative defense
provisions in the Portland Cement NESHAP rule. NRDC v. EPA, 749 F. 3d
at 1063-64 (D.C. Cir. 2014).

IV. Summary of Changes Since Proposal

    Section III summarized the amendments to the 2013 NSPS and NESHAP
rules that the EPA is finalizing in this rule. Due to public comments,
minor changes to the proposed regulatory text have been included in the
final rule. These minor changes are discussed in the response to
comment document that can be found in the docket. We believe that these
minor changes sufficiently address concerns expressed by commenters and
improve the clarity of the rule while improving or preserving public
health and environmental protection required under the CAA.

V. Summary of Comments and Responses

    We proposed amendments to the 2013 NSPS and NESHAP rules on
November 19, 2014 (see 79 FR 68821). We received 3 comment letters, and
consequently made some additional corrections in response to these
comments. Comments and responses on these amendments are summarized in
the response to comments document found in the docket. There were no
significant comments received on the proposed technical amendments. A
list of typographical errors we proposed to correct, and are now
finalizing, can be found in the proposed rule at 79 FR 68824. For
clarity, we are including a table of additional typographical
corrections found by the commenters on the proposed rule.

------------------------------------------------------------------------

    The EPA is also finalizing corrections and clarifications to the
2013 NESHAP and NSPS rules, including typographical and grammatical
errors, as well as incorrect dates and cross-references. Details of the
specific changes we are finalizing to the regulatory text may be found
above in the table of corrections, and also in the response to comment
document found in the docket for this action.

VI. Impacts of These Final Amendments

    The EPA has determined that owners and operators of affected
facilities would choose to install and operate the same or similar air
pollution control technologies under this action as they would have
installed to comply with the previously finalized standards. We project
that these amendments will result in no significant change in costs,
emission reductions or benefits. Even if there were changes in costs
for the affected facilities, such changes would likely be small
relative to both the overall costs of the individual projects and the
overall costs and benefits of the final rule. Since we believe that
owners and operators would put on the same controls for this revised
final rule that they would have for the 2013 rule, there should not be
any incremental costs related to this final rule.

A. What are the air impacts?

    We believe that owners and operators of affected facilities will
not revise their control technology implementation plans as a result of
these final technical corrections. Accordingly, we believe that this
final rule will not result in significant changes in emissions of any
regulated pollutants.

B. What are the energy impacts?

    This final rule is not anticipated to have an effect on the supply,
distribution or use of energy. As previously stated, we believe that
owners and operators of affected facilities would install the same or
similar control technologies as they would have installed to comply
with the previously finalized standards.

C. What are the compliance costs?

    We believe there will be no significant change in compliance costs
as a result of this final rule because owners and operators of affected
facilities would install the same or similar control technologies as
they would have installed to comply with the previously finalized
standards.

D. What are the economic and employment impacts?

    Because we expect that owners and operators of affected facilities
would install the same or similar control technologies under this
action as they would have installed to comply with the previously
finalized standards, we do not anticipate that this final rule will
result in significant changes in emissions, energy impacts, costs,
benefits or economic impacts. Likewise, we believe this rule will not
have any impacts on the price of electricity, employment or labor
markets, or the U.S. economy.

E. What are the benefits of the final standards?

    As previously stated, the EPA anticipates the Portland cement
industry will not incur significant compliance costs or savings as a
result of this action and we do not anticipate any significant emission
changes resulting from these amendments to the rule. Therefore, there
are no direct monetized benefits or disbenefits associated with this
final rule.

VII. Statutory and Executive Order Reviews

    Additional information about these statutes and Executive Orders
can be found at http://www2.epa.gov/laws-regulations/laws-and-executive-orders.

A. Executive Order 12866: Regulatory Planning and Review and Executive
Order 13563: Improving Regulation and Regulatory Review

    This action is not a significant regulatory action and was
therefore not submitted to the Office of Management and Budget (OMB)
for review.

B. Paperwork Reduction Act (PRA)

    This action does not impose any new information collection burden
under the PRA. The OMB has previously approved the information
collection activities contained in the existing regulations and has
assigned OMB control number 2060-0416 for the NESHAP; there are no
additional recordkeeping and reporting requirements for the NSPS. This
action does not change the information collection requirements
previously finalized and, as a result, does not impose any additional
information collection burden on industry. The OMB control numbers for
the EPA's regulations in 40 CFR are listed in 40 CFR part 9.

C. Regulatory Flexibility Act (RFA)

    I certify that this action will not have a significant economic
impact on a substantial number of small entities under the RFA. In
making this determination, the impact of concern is any significant
adverse economic impact on small entities. An agency may certify that a
rule will not have a significant economic impact on a substantial
number of small entities if the rule relieves regulatory burden, has no
net burden or otherwise has a positive economic effect on the small
entities subject to the rule. The EPA has determined that none of the
small entities subject to this rule will experience a significant
impact because this action imposes no additional compliance costs on
owners or operators of affected sources. We have therefore concluded
that this action will have no net regulatory burden for all directly
regulated small entities.

D. Unfunded Mandates Reform Act of 1995 (UMRA)

    This action does not contain any unfunded mandate as described in
UMRA, 2 U.S.C. 1531-1538, and does not significantly or uniquely affect
small governments. This action imposes no enforceable duty on any
state, local or tribal governments or the private sector.

E. Executive Order 13132: Federalism

    This action does not have federalism implications. It will not have
substantial direct effects on the states, on the relationship between
the national government and the states, or on the distribution of power
and responsibilities among the various levels of government.

F. Executive Order 13175: Consultation and Coordination With Indian
Tribal Governments

    This action does not have tribal implications as specified in
Executive Order 13175. It will not have substantial direct effect on
tribal governments, on the relationship between the federal government
and Indian tribes or on the distribution of power and responsibilities
between the federal government and Indian tribes, as specified in
Executive Order 13175. Thus, Executive Order 13175 does not apply to
this action.

G. Executive Order 13045: Protection of Children From Environmental
Health Risks and Safety Risks

    This action is not subject to Executive Order 13045 because it is
not economically significant as defined in Executive Order 12866, and
because the EPA does not believe the environmental health or safety
risks addressed by this action present a disproportionate risk to
children.
    This action does not add to or relieve affected sources from any
requirements, and therefore has no impacts; thus, health and risk
assessments were not conducted.

H. Executive Order 13211: Actions Concerning Regulations That
Significantly Affect Energy Supply, Distribution, or Use

    This action is not subject to Executive Order 13211 because it is
not a significant regulatory action under Executive Order 12866.

I. National Technology Transfer and Advancement Act (NTTAA)

    This rulemaking does not involve technical standards.

J. Executive Order 12898: Federal Actions To Address Environmental
Justice in Minority Populations and Low-Income Populations

    The EPA believes the human health or environmental risk addressed
by this action will not have potential disproportionately high and
adverse human health or environmental effects on minority, low-income
or indigenous populations because it does not affect the level of
protection provided to human health or the environment. The basis for
this determination is that this action is a reconsideration of existing
requirements and imposes no new impacts or costs.

K. Congressional Review Act (CRA)

    This action is subject to the CRA, and the EPA will submit a rule
report to each House of the Congress and to the Comptroller General of
the United States. This action is not a ``major rule'' as defined by 5
U.S.C. 804(2).

    For the reasons set out in the preamble, title 40, chapter I of the
Code of Federal Regulations is amended as follows:

PART 60--STANDARDS OF PERFORMANCE FOR NEW STATIONARY SOURCES

1. The authority citation for part 60 continues to read as follows:

    Authority: 42 U.S.C. 7411.

Subpart F--[Amended]

2. Section 60.61 is amended by revising paragraph (f) and adding
paragraphs (g) and (h) to read as follows:

Sec.  60.61  Definitions.

* * * * *
    (f) Operating day means a 24-hour period beginning at 12:00
midnight during which the kiln produces clinker at any time. For
calculating 30 day rolling average emissions, an operating day does not
include the hours of operation during startup or shutdown.
    (g) Rolling average means the weighted average of all data, meeting
QA/QC requirements or otherwise normalized, collected during the
applicable averaging period. The period of a rolling average stipulates
the frequency of data averaging and reporting. To demonstrate
compliance with an operating parameter a 30-day rolling average period
requires calculation of a new average value each operating day and
shall include the average of all the hourly averages of the specific
operating parameter. For demonstration of compliance with an emissions
limit based on pollutant concentration, a 30-day rolling average is
comprised of the average of all the hourly average concentrations over
the previous 30 operating days. For demonstration of compliance with an
emissions limit based on lbs-pollutant

per production unit, the 30-day rolling average is calculated by
summing the hourly mass emissions over the previous 30 operating days,
then dividing that sum by the total production during the same period.
    (h) Run average means the average of the recorded parameter values
for a run.

    (i) 0.30 pounds per ton of feed (dry basis) to the kiln for kilns
constructed, reconstructed, or modified after August 17, 1971 but on or
before June 16, 2008.
* * * * *
    (2) Exhibit greater than 20 percent opacity for kilns constructed,
reconstructed, or modified after August 17, 1971 but on or before June
16, 2008, except that this opacity limit does not apply to any kiln
subject to a PM limit in paragraph (a)(1) of this section that uses a
PM continuous parametric monitoring system (CPMS).
* * * * *
    (b) * * *
    (1) * * *
    (iii) 0.10 lb per ton of feed (dry basis) for clinker coolers
constructed, reconstructed, or modified after August 17, 1971, but on
or before June 16, 2008.
    (iv) 10 percent opacity for clinker coolers constructed,
reconstructed, or modified after August 17, 1971, but on or before June
16, 2008, except that this opacity limit does not apply to any clinker
cooler subject to a PM limit in paragraph (b)(1) of this section that
uses a PM continuous parametric monitoring system (CPMS).
* * * * *
    (d) If you have an affected source subject to this subpart with a
different emissions limit or requirement for the same pollutant under
another regulation in title 40 of this chapter, once you are in
compliance with the most stringent emissions limit or requirement, you
are not subject to the less stringent requirement. Until you are in
compliance with the more stringent limit, the less stringent limit
continues to apply.
    (e) The compliance date for all revised monitoring and
recordkeeping requirements contained in this rule will be the same as
listed in 63.1351(c) unless you commenced construction as of June 16,
2008, at which time the compliance date is November 8, 2010 or upon
startup, whichever is later.

4. Section 60.63 is amended by revising paragraphs (c)(1), (c)(2)(i)
and (iii), (c)(3), (c)(4)(ii) through (iv), and (c)(5) through (8) to
read as follows:

Sec.  60.63  Monitoring of operations.

* * * * *
    (c) * * *
    (1) For each kiln or clinker cooler subject to a PM emissions limit
in Sec. Sec.  60.62(a)1(ii) and 60.62(a)1(iii) or 60.62(b)(1)(i) and
60.62(b)(1)(ii), you must demonstrate compliance through an initial
performance test. You will conduct your performance test using Method 5
or Method 5I at appendix A-3 to part 60 of this chapter. You must also
monitor continuous performance through use of a PM CPMS.
    (2) * * *
    (i) Your PM CPMS must provide a 4-20 milliamp or digital signal
output and the establishment of its relationship to manual reference
method measurements must be determined in units of milliamps or the
monitors digital equivalent.
    (ii) * * *
    (iii) During the initial performance test or any such subsequent
performance test that demonstrates compliance with the PM limit, 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 your PM CPMS output values for three corresponding 2-hour Method 5I
test runs).
    (3) Determine your operating limit as specified in paragraphs
(c)(4)(i) through (c)(5) of this section. If your PM performance test
demonstrates your PM emission levels to be below 75 percent of your
emission limit, you will use the average PM CPMS value recorded during
the PM compliance test, the milliamp or digital equivalent of zero
output from your PM CPMS, and the average PM result of your compliance
test to establish your operating limit. If your PM compliance test
demonstrates your PM emission levels to be at or above 75 percent of
your emission limit, you will use the average PM CPMS value recorded
during the PM compliance test to establish your operating limit. You
must verify an existing or establish a new operating limit after each
repeated performance test. You must 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.
    (4) * * *
    (ii) Determine your PM CPMS instrument average in milliamps or
digital equivalent and the average of your corresponding three PM
compliance test runs, using equation 1.
[GRAPHIC] [TIFF OMITTED] TR27JY15.006

Where:

X1 = The PM CPMS data points for the three runs
constituting the performance test,
Y1 = The PM concentration value for the three runs
constituting the performance test, and
n = The number of data points.

    (iii) With your PM CPMS instrument zero expressed in milliamps or a
digital value, your three run average PM CPMS milliamp or digital
signal value, and your three run average PM concentration from your
three PM performance test runs, determine a relationship of lb/ton-
clinker per milliamp or digital signal with equation 2.
[GRAPHIC] [TIFF OMITTED] TR27JY15.007

Where:

R = The relative lb/ton clinker per milliamp or digital equivalent
for your PM CPMS.
Y1 = The three run average PM lb/ton clinker.

X1 = The three run average milliamp or digital signal
output from your PM CPMS.
z = The milliamp or digital equivalent of your instrument zero
determined from (c)(4)(i) of this section.

    (iv) Determine your source specific 30-day rolling average
operating limit using the lb/ton-clinker per milliamp or digital signal
value from Equation 2 above in Equation 3, below. This sets your
operating limit at the PM CPMS output value corresponding to 75 percent
of your emission limit.
[GRAPHIC] [TIFF OMITTED] TR27JY15.008

Where:

Ol = The operating limit for your PM CPMS on a 30-day
rolling average, in milliamps or the digital equivalent.
L = Your source emission limit expressed in lb/ton clinker.
z = Your instrument zero in milliamps or a digital equivalent,
determined from (1)(i).
R = The relative lb/ton-clinker per milliamp or digital equivalent,
for your PM CPMS, from Equation 2.

    (5) If the average of your three PM compliance test runs is at or
above 75 percent of your PM emission limit, you must determine your
operating limit by averaging the PM CPMS milliamp or digital equivalent
output corresponding to your three PM performance test runs that
demonstrate compliance with the emission limit using Equation 4.
[GRAPHIC] [TIFF OMITTED] TR27JY15.009

Where:

X1 = The PM CPMS data points for all runs i.
n = The number of data points.
Oh = Your site specific operating limit, in milliamps or
digital equivalent.

    (6) To determine continuous compliance, you must 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. You must 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. Use Equation 5 to determine the 30 kiln
operating day average.
[GRAPHIC] [TIFF OMITTED] TR27JY15.010

Where:

Hpvi = The hourly parameter value for hour i.
n = The number of valid hourly parameter values collected over the
previous 30 kiln operating days.

    (7) Use EPA Method 5 or Method 5I of appendix A to part 60 of this
chapter to determine PM emissions. For each performance test, conduct
at least three separate 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 2 dscm for determining
compliance with a new source limit and 1 dscm for determining
compliance with an existing source limit. Calculate the time weighted
average of the results from three consecutive runs to determine
compliance. You 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 of this
subpart. This shall not preclude the permitting authority from
requiring a determination of the ``back half'' for other purposes.
    (8) For PM performance test reports used to set a PM CPMS operating
limit, the electronic submission of the test report must also include
the make and model of the PM CPMS instrument, serial number of the
instrument, analytical principle of the instrument (e.g. beta
attenuation), span of the instruments primary analytical range,
milliamp or digital signal value equivalent to the instrument zero
output, technique by which this zero value was determined, and the
average milliamp or digital equivalent signals corresponding to each PM
compliance test run.

7. Section 63.1341 is amended by revising the definitions for
``Operating day'', ``Rolling average'', and ``Run average'' to read as
follows:

Sec.  63.1341  Definitions.

* * * * *

    Operating day means any 24-hour period beginning at 12:00 midnight
during which the kiln produces any amount of clinker. For calculating
the 30-day rolling average emissions, kiln operating days do not
include the hours of operation during startup or shutdown.
* * * * *
    Rolling average means the weighted average of all data, meeting QA/
QC requirements or otherwise normalized, collected during the
applicable averaging period. The period of a rolling average stipulates
the frequency of data averaging and reporting. To demonstrate
compliance with an operating parameter a 30-day rolling average period
requires calculation of a new average value each operating day and
shall include the average of all the hourly averages of the specific
operating parameter. For demonstration of compliance with an emissions
limit based on pollutant concentration a 30-day rolling average is
comprised of the average of all the hourly average concentrations over
the previous 30 operating days. For demonstration of compliance with an
emissions limit based on lbs-pollutant per production unit the 30-day
rolling average is calculated by summing the hourly mass emissions over
the previous 30 operating days, then dividing that sum by the total
production during the same period.
    Run average means the average of the recorded parameter values for
a run.

8. Section 63.1343 is amended by revising paragraphs (a), (b)(1) and
(2), and (d) to read as follows:

Sec.  63.1343  What standards apply to my kilns, clinker coolers, raw
material dryers, and open clinker storage piles?

    (a) General. The provisions in this section apply to each kiln and
any alkali bypass associated with that kiln, clinker cooler, raw
material dryer, and open clinker storage pile. All D/F, HCl, and total
hydrocarbon (THC) emissions limit are on a dry basis. The D/F, HCl, and
THC limits for kilns are corrected to 7 percent oxygen. All THC
emissions limits are measured as propane. Standards for mercury and THC
are based on a rolling 30-day average. If using a CEMS to determine
compliance with the HCl standard, this standard is based on a rolling
30-day average. You must ensure appropriate corrections for moisture
are made when measuring flow rates used to calculate mercury emissions.
The 30-day period means all operating hours within 30 consecutive kiln
operating days excluding periods of startup and shutdown. All emissions
limits for kilns, clinker coolers, and raw material dryers currently in
effect that are superseded by the limits below continue to apply until
the compliance date of the limits below, or until the source certifies
compliance with the limits below, whichever is earlier.
    (b) Kilns, clinker coolers, raw material dryers, raw mills, and
finish mills. (1) The emissions limits for these sources are shown in
Table 1.

with the kiln exhaust and send the combined exhaust to the PM control
device as a single stream may meet an alternative PM emissions limit.
This limit is calculated using Equation 1 of this section:

[GRAPHIC] [TIFF OMITTED] TR27JY15.011

Where:

PMalt = Alternative PM emission limit for commingled
sources.
0.006 = The PM exhaust concentration (gr/dscf) equivalent to 0.070
lb per ton clinker where clinker cooler and kiln exhaust gas are not
combined.
1.65 = The conversion factor of ton feed per ton clinker.
Qk = The exhaust flow of the kiln (dscf/ton feed).
Qc = The exhaust flow of the clinker cooler (dscf/ton
feed).
Qab = The exhaust flow of the alkali bypass (dscf/ton
feed).
Qcm = The exhaust flow of the coal mill (dscf/ton feed).
7000 = The conversion factor for grains (gr) per lb.

    For new kilns that combine kiln exhaust, clinker cooler gas and/or
coal mill and alkali bypass exhaust, the limit is calculated using
Equation 2 of this section:

lb per ton clinker where clinker cooler and kiln exhaust gas are not
combined.
1.65 = The conversion factor of ton feed per ton clinker.
Qk = The exhaust flow of the kiln (dscf/ton feed).
Qc = The exhaust flow of the clinker cooler (dscf/ton
feed).
Qab = The exhaust flow of the alkali bypass (dscf/ton
feed).
Qcm = The exhaust flow of the coal mill (dscf/ton feed).

13. Section 63.1349 is amended by revising paragraphs (b), (c), and
(d)(1)(ii) to read as follows:

Sec.  63.1349  Performance testing requirements.

* * * * *
    (b)(1) PM emissions tests. The owner or operator of a kiln and
clinker cooler subject to limitations on PM emissions shall demonstrate
initial compliance by conducting a performance test using Method 5 or
Method 5I at appendix A-3 to part 60 of this chapter. You must also
monitor continuous performance through use of a PM continuous
parametric monitoring system (PM CPMS).
    (i) For your PM CPMS, you will establish a site-specific operating
limit. If your PM performance test demonstrates your PM emission levels
to be below 75 percent of your emission limit you will use the average
PM CPMS value recorded during the PM compliance test, the milliamp or
digital equivalent of zero output from your PM CPMS, and the average PM
result of your compliance test to establish your operating limit. If
your PM compliance test demonstrates your PM emission levels to be at
or above 75 percent of your emission limit you will use the average PM
CPMS value recorded during the PM compliance test to establish your
operating limit. You will use the PM CPMS to demonstrate continuous
compliance with your operating limit. You must repeat the performance
test annually and reassess and adjust the site-specific operating limit
in accordance with the results of the performance test.
    (A) Your PM CPMS must provide a 4-20 milliamp or digital signal
output and the establishment of its relationship to manual reference
method measurements must be determined in units of milliamps or the
monitors digital equivalent.
    (B) Your PM CPMS operating range must be capable of reading PM
concentrations from zero to a level equivalent to three times your
allowable emission limit. If your PM CPMS is an auto-ranging instrument
capable of multiple scales, the primary range of the instrument must be
capable of reading PM concentration from zero to a level equivalent to
three times your allowable emission limit.
    (C) During the initial performance test or any such subsequent
performance test that demonstrates compliance with the PM limit, 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 your PM CPMS output values for three corresponding Method 5I test
runs).
    (ii) Determine your operating limit as specified in paragraphs
(b)(1)(iii) through (iv) of this section. If your PM performance test
demonstrates your PM emission levels to be below 75 percent of your
emission limit you will use the average PM CPMS value recorded during
the PM compliance test, the milliamp or digital equivalent of zero
output from your PM CPMS, and the average PM result of your compliance
test to establish your operating limit. If your PM compliance test
demonstrates your PM emission levels to be at or above 75 percent of
your emission limit you will use the average PM CPMS value recorded
during the PM compliance test to establish your operating limit. You
must verify an existing or establish a new operating limit after each
repeated performance test. You must 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 your three Method 5 or 5I compliance test
runs is below 75 percent of your PM emission limit, you must 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 (b)(1)(iii)(A) through (D) of this section.
    (A) Determine your PM CPMS instrument zero output with one of the
following procedures:
    (1) Zero point data for in-situ instruments should be obtained by
removing the instrument from the stack and monitoring ambient air on a
test bench.
    (2) Zero point data for extractive instruments should be obtained
by removing the extractive probe from the stack and drawing in clean
ambient air.
    (3) The zero point may also be established by performing manual
reference method measurements when the flue gas is free of PM emissions
or contains very low PM concentrations (e.g., when your process is not
operating, but the fans are operating or your source is combusting only
natural gas) and plotting these with the compliance data to find the
zero intercept.
    (4) If none of the steps in paragraphs (b)(1)(iii)(A)(1) through
(3) of this section are possible, you must use a zero output value
provided by the manufacturer.
    (B) Determine your PM CPMS instrument average in milliamps or
digital equivalent, and the average of your corresponding three PM
compliance test runs, using equation 3.
[GRAPHIC] [TIFF OMITTED] TR27JY15.013

Where:

X1 = The PM CPMS data points for the three runs
constituting the performance test.
Y1 = The PM concentration value for the three runs
constituting the performance test.
n = The number of data points.

    (C) With your instrument zero expressed in milliamps or a digital
value, your three run average PM CPMS milliamp or digital signal value,
and your three run PM compliance test average, determine a relationship
of lb/ton-clinker per milliamp or digital signal value with Equation 4.
[GRAPHIC] [TIFF OMITTED] TR27JY15.014

Where:

R = The relative lb/ton-clinker per milliamp or digital equivalent
for your PM CPMS.
Y1 = The three run average lb/ton-clinker PM
concentration.
X1 = The three run average milliamp or digital equivalent
output from your PM CPMS.
z = The milliamp or digital equivalent of your instrument zero
determined from (b)(1)(iii)(A).

* * * * *
    (D) Determine your source specific 30-day rolling average operating
limit using the lb/ton-clinker per milliamp or digital signal value
from Equation 4 in Equation 5, below. This sets your operating limit at
the PM CPMS output value corresponding to 75 percent of your emission
limit.
[GRAPHIC] [TIFF OMITTED] TR27JY15.015

Where:

* * * * *
Ol = The operating limit for your PM CPMS on a 30-day
rolling average, in milliamps or the digital equivalent.
L = Your source emission limit expressed in lb/ton clinker.
z = Your instrument zero in milliamps, or digital equivalent,
determined from (b)(1)(iii)(A).
R = The relative lb/ton-clinker per milliamp, or digital equivalent,
for your PM CPMS, from Equation 4.

* * * * *
    (iv) If the average of your three PM compliance test runs is at or
above 75 percent of your PM emission limit you must determine your
operating limit by averaging the PM CPMS milliamp or digital equivalent
output corresponding to your three PM performance test runs that
demonstrate compliance with the emission limit using Equation 6.
[GRAPHIC] [TIFF OMITTED] TR27JY15.016

Where:

* * * * *
X1 = The PM CPMS data points for all runs i.
n = The number of data points.
Oh = Your site specific operating limit, in milliamps or
the digital equivalent.

* * * * *

    (v) To determine continuous operating compliance, you must 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. You must 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. Use Equation 7 to determine the 30 kiln
operating day average.
[GRAPHIC] [TIFF OMITTED] TR27JY15.017

Where:

Hpvi = The hourly parameter value for hour i.
n = The number of valid hourly parameter values collected over 30
kiln operating days.

* * * * *
    (vi) For each performance test, 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 2 dscm for determining compliance with a new
source limit and 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 as required by
(b)(1)(viii), to determine compliance. You 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 of this subpart. This shall not
preclude the permitting authority from requiring a determination of the
``back half'' for other purposes.
    (vii) For PM performance test reports used to set a PM CPMS
operating limit, the electronic submission of the test report must also
include the make and model of the PM CPMS instrument, serial number of
the instrument, analytical principle of the instrument (e.g. beta
attenuation), span of the instruments primary analytical range,
milliamp value or digital equivalent to the instrument zero output,
technique by which this zero value was determined, and the average
milliamp or digital equivalent signals corresponding to each PM
compliance test run.
    (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 must be tested simultaneously and
the combined emission rate of PM from the kiln and alkali bypass and/or
inline coal mill must be computed for each run using Equation 8 of this
section.
[GRAPHIC] [TIFF OMITTED] TR27JY15.018

Where:

ECm = Combined hourly emission rate of PM from the kiln
and bypass stack and/or inline coal mill, lb/ton of kiln clinker
production.
EK = Hourly emissions of PM emissions from the kiln, lb.
EB = Hourly PM emissions from the alkali bypass stack,
lb.
EC = Hourly PM emissions from the inline coal mill stack,
lb.
P = Hourly clinker production, tons.

    (ix) The owner or operator of a kiln with an in-line raw mill and
subject to limitations on PM emissions 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 will then be determined using 63.1349(b)(1)(i) of this
section.
    (2) Opacity tests. If you are subject to limitations on opacity
under this subpart, you must conduct opacity tests in accordance with
Method 9 of appendix A-4 to part 60 of this chapter. The duration of
the Method 9 performance test must be 3 hours (30 6-minute averages),
except that the duration of the Method 9 performance test may be
reduced to 1 hour if the conditions of paragraphs (b)(2)(i) and (ii) of
this section apply. For batch processes that are not run for 3-hour
periods or longer, compile observations totaling 3 hours when the unit
is operating.
    (i) There are no individual readings greater than 10 percent
opacity;
    (ii) There are no more than three readings of 10 percent for the
first 1-hour period.
    (3) D/F Emissions Tests. If you are subject to limitations on D/F
emissions under this subpart, you must conduct a performance test using
Method 23 of appendix A-7 to part 60 of this chapter. If your kiln or
in-line kiln/raw mill is equipped with an alkali bypass, you must
conduct simultaneous performance tests of the kiln or in-line kiln/raw
mill exhaust and the alkali bypass. You may conduct a performance test
of the alkali bypass exhaust when the raw mill of the in-line kiln/raw
mill is operating or not operating.
    (i) Each performance test must consist of three separate runs
conducted under representative conditions. The duration of each run
must be at least 3 hours, and the sample volume for each run must be at
least 2.5 dscm (90 dscf).
    (ii) The temperature at the inlet to the kiln or in-line kiln/raw
mill PMCD, and, where applicable, the temperature at the inlet to the
alkali bypass PMCD must be continuously recorded during the period of
the Method 23 test, and the continuous temperature record(s) must be
included in the performance test report.
    (iii) Average temperatures must be calculated for each run of the
performance test.
    (iv) The run average temperature must be calculated for each run,
and the average of the run average temperatures must be determined and
included in the performance test report and will determine the
applicable temperature limit in accordance with Sec.  63.1346(b),
footnote 2.
    (v)(A) If sorbent injection is used for D/F control, you must
record the rate of sorbent injection to the kiln exhaust, and where
applicable, the rate of sorbent injection to the alkali bypass exhaust,
continuously during the period of the Method 23 test in accordance with
the conditions in Sec.  63.1350(m)(9), and include the continuous
injection rate record(s) in the performance test report. Determine the
sorbent injection rate parameters in accordance with paragraph
(b)(3)(vi) of this section.
    (B) Include the brand and type of sorbent used during the
performance test in the performance test report.
    (C) Maintain a continuous record of either the carrier gas flow
rate or the carrier gas pressure drop for the duration of the
performance test. If the carrier gas flow rate is used, determine,

record, and maintain a record of the accuracy of the carrier gas flow
rate monitoring system according to the procedures in appendix A to
part 75 of this chapter. If the carrier gas pressure drop is used,
determine, record, and maintain a record of the accuracy of the carrier
gas pressure drop monitoring system according to the procedures in
Sec.  63.1350(m)(6).
    (vi) Calculate the run average sorbent injection rate for each run
and determine and include the average of the run average injection
rates in the performance test report and determine the applicable
injection rate limit in accordance with Sec.  63.1346(c)(1).
    (4) THC emissions test. (i) If you are subject to limitations on
THC emissions, you must operate a CEMS in accordance with the
requirements in Sec.  63.1350(i). For the purposes of conducting the
accuracy and quality assurance evaluations for CEMS, the THC span value
(as propane) is 50 ppmvd and the reference method (RM) is Method 25A of
appendix A to part 60 of this chapter.
    (ii) Use the THC CEMS to conduct the initial compliance test for
the first 30 kiln operating days of kiln operation after the compliance
date of the rule. See Sec.  63.1348(a).
    (iii) If kiln gases are diverted through an alkali bypass or to a
coal mill and exhausted through a separate stack, you must calculate a
kiln-specific THC limit using Equation 9:
[GRAPHIC] [TIFF OMITTED] TR27JY15.019

Where:

Cks = Kiln stack concentration (ppmvd).
Qab = Alkali bypass flow rate (volume/hr).
Cab = Alkali bypass concentration (ppmvd).
Qcm = Coal mill flow rate (volume/hr).
Ccm = Coal mill concentration (ppmvd).
Qks = Kiln stack flow rate (volume/hr).

    (iv) THC must be measured either upstream of the coal mill or the
coal mill stack.
    (v) Instead of conducting the performance test specified in
paragraph (b)(4)of this section, you may conduct a performance test to
determine emissions of total organic HAP by following the procedures in
paragraph (b)(7) of this section.
    (5) Mercury Emissions Tests. If you are subject to limitations on
mercury emissions, you must operate a mercury CEMS or a sorbent trap
monitoring system in accordance with the requirements of Sec.
63.1350(k). The initial compliance test must be based on the first 30
kiln operating days in which the affected source operates using a
mercury CEMS or a sorbent trap monitoring system after the compliance
date of the rule. See Sec.  63.1348(a).
    (i) If you are using a mercury CEMS or a sorbent trap monitoring
system, you must 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 Sec.
63.1350(k)(5).
    (ii) Calculate the emission rate using Equation 10 of this section:
    [GRAPHIC] [TIFF OMITTED] TR27JY15.020

Where:

E30D = 30-day rolling emission rate of mercury, lb/MM
tons clinker.
Ci = Concentration of mercury for operating hour i,
[micro]g/scm.
Qi = Volumetric flow rate of effluent gas for operating
hour i, where Ci and Qi are on the same basis
(either wet or dry), scm/hr.
k = Conversion factor, 1 lb/454,000,000 [micro]g.
n = Number of kiln operating hours in the previous 30 kiln operating
day period where both C and Qi qualified data are available.
P = Total runs from the previous 30 days of clinker production
during the same time period as the mercury emissions measured,
million tons.

    (6) HCl emissions tests. For a source subject to limitations on HCl
emissions you must conduct performance testing by one of the following
methods:
    (i)(A) If the source is equipped with a wet scrubber, tray tower or
dry scrubber, you must conduct performance testing using Method 321 of
appendix A to this part unless you have installed a CEMS that meets the
requirements Sec.  63.1350(l)(1). For kilns with inline raw mills,
testing should be conducted for the raw mill on and raw mill off
conditions.
    (B) You must establish site specific parameter limits by using the
CPMS required in Sec.  63.1350(l)(1). For a wet scrubber or tray tower,
measure and record the pressure drop across the scrubber and/or liquid
flow rate and pH in intervals of no more than 15 minutes during the HCl
test. Compute and record the 24-hour average pressure drop, pH, and
average scrubber water flow rate for each sampling run in which the
applicable emissions limit is met. For a dry scrubber, measure and
record the sorbent injection rate in intervals of no more than 15
minutes during the HCl test. Compute and record the 24-hour average
sorbent injection rate and average sorbent injection rate for each
sampling run in which the applicable emissions limit is met.
    (ii)(A) If the source is not controlled by a wet scrubber, tray
tower or dry sorbent injection system, you must operate a CEMS in
accordance with the requirements of Sec.  63.1350(l)(1). See Sec.
63.1348(a).
    (B) The initial compliance test must be based on the 30 kiln
operating days that occur after the compliance date of this rule in
which the affected source operates using an HCl CEMS. Hourly HCl
concentration data must be obtained according to Sec.  63.1350(l).
    (iii) As an alternative to paragraph (b)(6)(i)(B) of this section,
you may choose to monitor SO2 emissions using a CEMS in
accordance with the requirements of Sec.  63.1350(l)(3). You must
establish an SO2 operating limit equal to the average
recorded during the HCl stack test where the HCl stack test run result
demonstrates compliance with the emission limit. This operating limit
will apply only for demonstrating HCl compliance.
    (iv) If kiln gases are diverted through an alkali bypass or to a
coal mill and exhausted through a separate stack, you must calculate a
kiln-specific HCl limit using Equation 11:
[GRAPHIC] [TIFF OMITTED] TR27JY15.021

Where:

Cks = Kiln stack concentration (ppmvd).
Qab = Alkali bypass flow rate (volume/hr).

Cab = Alkali bypass concentration (ppmvd).
Qcm = Coal mill flow rate (volume/hr).
Ccm = Coal mill concentration (ppmvd).
Qks = Kiln stack flow rate (volume/hr).

    (7) Total Organic HAP Emissions Tests. Instead of conducting the
performance test specified in paragraph (b)(4) of this section, you may
conduct a performance test to determine emissions of total organic HAP
by following the procedures in paragraphs (b)(7)(i) through (v) of this
section.
    (i) Use Method 320 of appendix A to this part, Method 18 of
Appendix A of part 60, ASTM D6348-03 or a combination to determine
emissions of total organic HAP. Each performance test must consist of
three separate runs under the conditions that exist when the affected
source is operating at the representative performance conditions in
accordance with Sec.  63.7(e). Each run must be conducted for at least
1 hour.
    (ii) At the same time that you are conducting the performance test
for total organic HAP, you must also determine a site-specific THC
emissions limit by operating a THC CEMS in accordance with the
requirements of Sec.  63.1350(j). The duration of the performance test
must be at least 3 hours and the average THC concentration (as
calculated from the recorded output) during the 3-hour test must be
calculated. You must establish your THC operating limit and determine
compliance with it according to paragraphs (b)(7)(vii) and (viii) of
this section. It is permissible to extend the testing time of the
organic HAP performance test if you believe extended testing is
required to adequately capture organic HAP and/or THC variability over
time.
    (iii) If your source has an in-line kiln/raw mill you must 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 your organic HAP emissions are below 75 percent of the
organic HAP standard and you determine your operating limit with
paragraph (b)(7)(vii) of this section your THC CEMS must be calibrated
and operated on a measurement scale no greater than 180 ppmvw, as
carbon, or 60 ppmvw as propane.
    (v) If your kiln has an inline coal mill and/or an alkali bypass
with separate stacks, you are required to measure and account for oHAP
emissions from their separate stacks. You are required to measure oHAP
at the coal mill inlet, and you must also measure oHAP at the alkali
bypass outlet. You must then calculate a flow weighted average oHAP
concentration for all emission sources including the inline coal mill
and the alkali bypass.
    (vi) Your THC CEMS measurement scale must be capable of reading THC
concentrations from zero to a level equivalent to two times your
highest THC emissions average determined during your 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
(b)(7)(iv) of this section.
    (vii) Determine your operating limit as specified in paragraphs
(b)(7)(viii) and (ix) of this section. If your organic HAP performance
test demonstrates your average organic HAP emission levels are below 75
percent of your emission limit (9 ppmv) you will use the average THC
value recorded during the organic HAP performance test, and the average
total organic HAP result of your performance test to establish your
operating limit. If your organic HAP compliance test results
demonstrate that your average organic HAP emission levels are at or
above 75 percent of your emission limit, your operating limit is
established as the average THC value recorded during the organic HAP
performance test. You must establish a new operating limit after each
performance test. You must repeat the performance test no later than 30
months following your last performance test and reassess and adjust the
site-specific operating limit in accordance with the results of the
performance test.
    (viii) If the average organic HAP results for your three Method 18
and/or Method 320 performance test runs are below 75 percent of your
organic HAP emission limit, you must 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 (b)(7)(viii)(A) and (B) of this
section.
    (A) Determine the THC CEMS average values in ppmvw, and the average
of your corresponding three total organic HAP compliance test runs,
using Equation 12.
[GRAPHIC] [TIFF OMITTED] TR27JY15.022

Where:

x = The THC CEMS average values in ppmvw.
Xi = The THC CEMS data points for all three runs i.
Yi = The sum of organic HAP concentrations for test runs
i. and
n = The number of data points.

    (B) You must use your three run average THC CEMS value and your
three run average organic HAP concentration from your three Method 18
and/or Method 320 compliance tests to determine the operating limit.
Use equation 13 to determine your operating limit in units of ppmvw
THC, as propane.
[GRAPHIC] [TIFF OMITTED] TR27JY15.023

Where:

Tl = The 30-day operating limit for your THC CEMS, ppmvw.
Y1 = The average organic HAP concentration from Eq. 12,
ppmvd.
X1 = The average THC CEMS concentration from Eq. 12,
ppmvw.

    (ix) If the average of your three organic HAP performance test runs
is at or above 75 percent of your organic HAP emission limit, you must
determine your operating limit using Equation 14 by averaging the THC
CEMS output values corresponding to your three organic HAP performance
test runs that demonstrate compliance with the emission limit. If your
new THC CEMS value is below your current operating limit, you may opt
to retain your current operating limit, but you must still submit all
performance test and THC CEMS data according to the reporting
requirements in paragraph (d)(1) of this section.

[GRAPHIC] [TIFF OMITTED] TR27JY15.024

Where:

X1 = The THC CEMS data points for all runs i.
n = The number of data points.
Th = Your site specific operating limit, in ppmvw THC.

    (x) If your kiln has an inline kiln/raw mill, you must 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
with Equation 15.
[GRAPHIC] [TIFF OMITTED] TR27JY15.025

Where:

R = Operating limit as THC, ppmvw.
y = Average THC CEMS value during mill on operations, ppmvw.
t = Percentage of operating time with mill on.
x = Average THC CEMS value during mill off operations, ppmvw.
(1-t) = Percentage of operating time with mill off.

    (xi) To determine continuous compliance with the THC operating
limit, you must record the THC CEMS output data for all periods when
the process is operating and the THC CEMS is not out-of-control. You
must 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. Use Equation 16 to
determine the 30 kiln operating day average.
[GRAPHIC] [TIFF OMITTED] TR27JY15.026

Where:

Hpvi = The hourly parameter value for hour i, ppmvw.
n = The number of valid hourly parameter values collected over 30
kiln operating days.

    (xii) Use EPA Method 18 or Method 320 of appendix A to part 60 of
this chapter 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. If your source has an in-line kiln/raw mill you must
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.
    (xiii) If the THC level exceeds by 10 percent or more your site-
specific THC emissions limit, you must
    (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 your site-specific THC emissions limit.
    (8) HCl Emissions Tests with SO2 Monitoring. If you
choose to monitor SO2 emissions using a CEMS to demonstrate
HCl compliance, follow the procedures in (b)(8)(i) through (ix) of this
section and in accordance with the requirements of Sec.  63.1350(l)(3).
You must establish an SO2 operating limit equal to the
average recorded during the HCl stack test. This operating limit will
apply only for demonstrating HCl compliance.
    (i) Use Method 321 of appendix A to this part to determine
emissions of HCl. Each performance test must consist of three separate
runs under the conditions that exist when the affected source is
operating at the representative performance conditions in accordance
with Sec.  63.7(e). Each run must be conducted for at least one hour.
    (ii) At the same time that you are conducting the performance test
for HCl, you must also determine a site-specific SO2
emissions limit by operating an SO2 CEMS in accordance with
the requirements of Sec.  63.1350(l). The duration of the performance
test must be three hours and the average SO2 concentration
(as calculated from the average output) during the 3-hour test must be
calculated. You must establish your SO2 operating limit and
determine compliance with it according to paragraphs (b)(8)(vii) and
(viii) of this section.
    (iii) If your source has an in-line kiln/raw mill you must 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
SO2 levels measured during raw mill on and raw mill off
testing.
    (iv) Your SO2 CEMS must be calibrated and operated
according to the requirements of Sec.  60.63(f).
    (v) Your SO2 CEMS measurement scale must be capable of
reading SO2 concentrations consistent with the requirements
of Sec.  60.63(f), including mill on or mill off operation.
    (vi) If your kiln has an inline kiln/raw mill, you must 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 HCl
levels measured during raw mill on and raw mill off compliance testing
with Equation 17.

[GRAPHIC] [TIFF OMITTED] TR27JY15.027

Where:

R = Operating limit as SO2, ppmvw.
y = Average SO2 CEMS value during mill on operations,
ppmvw.
t = Percentage of operating time with mill on, expressed as a
decimal.
x = Average SO2 CEMS value during mill off operations,
ppmvw.
t-1 = Percentage of operating time with mill off, expressed as a
decimal.

    (vii) If the average of your three HCl compliance test runs is
below 75 percent of your HCl emission limit, you may as a compliance
alternative, calculate an operating limit by establishing a
relationship of SO2 CEMS signal to your HCl concentration
corrected to 7 percent O2 by using the SO2 CEMS
instrument zero, the average SO2 CEMS values corresponding
to the three compliance test runs, and the average HCl concentration
from the HCl compliance test with the procedures in (b)(8)(vii)(A)
through (D) of this section.
    (A) Determine your SO2 CEMS instrument zero output with
one of the following procedures:
    (1) Zero point data for in-situ instruments should be obtained by
removing the instrument from the stack and monitoring ambient air on a
test bench.
    (2) Zero point data for extractive instruments may be obtained by
removing the extractive probe from the stack and drawing in clean
ambient air.
    (3) The zero point may also be established by performing probe-
flood introduction of high purity nitrogen or certified zero air free
of SO2.
    (4) If none of the steps in paragraphs (b)(8)(vii)(A)(1) through
(3) of this section are possible, you must use a zero output value
provided by the manufacturer.
    (B) Determine your SO2 CEMS instrument average ppm, and
the average of your corresponding three HCl compliance test runs, using
equation 18.
[GRAPHIC] [TIFF OMITTED] TR27JY15.028

Where:

X1 = The SO2 CEMS data points for the three
runs constituting the performance test.
Y1 = The HCl emission concentration expressed as ppmv
corrected to 7 percent O2 for the three runs constituting
the performance test.
n = The number of data points.

    (C) With your instrument zero expressed in ppmv, your three run
average SO2 CEMS expressed in ppmv, and your three run HCl
compliance test average in ppm corrected to 7 percent O2,
determine a relationship of ppm HCl corrected to 7 percent
O2 per ppm SO2 with Equation 19.
[GRAPHIC] [TIFF OMITTED] TR27JY15.029

Where:

R = The relative HCl ppmv corrected to 7 percent O2 per
ppm SO2 for your SO2 CEMS.
Y1 = The three run average HCl concentration corrected to
7 percent O2.
X1 = The three run average ppm recorded by your
SO2 CEMS.
z = The instrument zero output ppm value.

    (D) Determine your source specific 30-day rolling average operating
limit using ppm HCl corrected to 7 percent O2 per ppm
SO2 value from Equation 19 in Equation 20, below. This sets
your operating limit at the SO2 CEMS ppm value corresponding
to 75 percent of your emission limit.
[GRAPHIC] [TIFF OMITTED] TR27JY15.030

Where:

Ol = The operating limit for your SO2 CEMS on
a 30-day rolling average, in ppmv.
L = Your source HCl emission limit expressed in ppmv corrected to 7
percent O2.
z = Your instrument zero in ppmv, determined from (1)(i).
R = The relative oxygen corrected ppmv HCl per ppmv SO2,
for your SO2 CEMS, from Equation 19.

    (viii) To determine continuous compliance with the SO2
operating limit, you must record the SO2 CEMS output data
for all periods when the process is operating and the SO2
CEMS is not out-of-control. You must demonstrate continuous compliance
by using all quality-assured hourly average data collected by the
SO2 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. Use Equation 21 to determine the 30 kiln
operating day average.
[GRAPHIC] [TIFF OMITTED] TR27JY15.031

Where:

Hpvi = The hourly parameter value for hour i, ppmvw.
n = The number of valid hourly parameter values collected over 30
kiln operating days.

    (ix) Use EPA Method 321 of appendix A to part 60 of this chapter to
determine HCl 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. If your
source has an in-line kiln/raw mill you must 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.
    (x) If the SO2 level exceeds by 10 percent or more your
site-specific SO2 emissions limit, you must:
    (A) As soon as possible but no later than 30 days after the
exceedance, conduct an inspection and take corrective action to return
the SO2 CEMS measurements to within the established value;
    (B) Within 90 days of the exceedance or at the time of the periodic
compliance test, whichever comes first, conduct another performance
test to determine compliance with the HCl limit and to verify or re-
establish your site-specific SO2 emissions limit.
    (c) Performance test frequency. Except as provided in Sec.
63.1348(b), performance tests are required at regular intervals for
affected sources that are subject to a dioxin, organic HAP or HCl
emissions limit. Performance tests required every 30 months must be
completed between 29 and 31 calendar months after the previous
performance test except where that specific pollutant is monitored
using CEMS; performance tests required every 12 months must be
completed within 11 to 13 calendar months after the previous
performance test.

Sec.  63.1350  Monitoring requirements.

* * * * *
    (i) * * *
    (1) You must install, operate, and maintain a THC continuous
emission monitoring system in accordance with Performance Specification
8 or Performance Specification 8A of appendix B to part 60 of this
chapter and comply with all of the requirements for continuous
monitoring systems found in the general provisions, subpart A of this
part. The owner or operator must operate and maintain each CEMS
according to the quality assurance requirements in Procedure 1 of
appendix F in part 60 of this chapter. 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.
    (2) Performance tests on alkali bypass and coal mill stacks must be
conducted using Method 25A in appendix A to 40 CFR part 60 and repeated
every 30 months.
    (j) Total organic HAP monitoring requirements. If you are complying
with the total organic HAP emissions limits, you must continuously
monitor THC according to paragraph (i)(1) and (2) of this section or in
accordance with Performance Specification 8 or Performance
Specification 8A of appendix B to part 60 of this chapter and comply
with all of the requirements for continuous monitoring systems found in
the general provisions, subpart A of this part. You must operate and
maintain each CEMS according to the quality assurance requirements in
Procedure 1 of appendix F in part 60 of this chapter. In addition, your
must follow the monitoring requirements in paragraphs (m)(1) through
(4) of this section. You must also develop an emissions monitoring plan
in accordance with paragraphs (p)(1) through (4) of this section.
    (k) * * *
    (2) In order to quality assure data measured above the span value,
you must use one of the three options in paragraphs (k)(2)(i) through
(iii) of this section. Where the options in paragraphs (k)(2)(i)
through (iii) are employed while the kiln is operating in a mill-off
mode, the ``above span'' described in paragraph (k)(2)(iii) may
substitute for the daily upscale calibration provided the data
normalization process in paragraph (k)(2)(iii) are not required. If
data normalization is required, the normal daily upscale calibration
check must be performed to quality assure the operation of the CEMS for
that day. In this particular case, adjustments to CEMS normally
required by Procedure 5 when a daily upscale does not meet the 5
percent criterion are not required, unless paragraph (k)(2)(iii) of
this section data normalization is necessary and a subsequent normal
daily calibration check demonstrates the need for such adjustment.
* * * * *
    (ii) Quality assure any data above the span value by proving
instrument linearity beyond the span value established in paragraph
(k)(1) of this section using the following procedure. Conduct a weekly
``above span linearity'' calibration challenge of the monitoring system
using a reference gas with a certified value greater than your highest
expected hourly concentration or greater than 75 percent of the highest
measured hourly concentration. The ``above span'' reference gas must
meet the requirements of PS 12A, Section 7.1 and must be introduced to
the measurement system at the probe. Record and report the results of
this procedure as you would for a daily calibration. The ``above span
linearity'' challenge is successful if the value measured by the Hg
CEMS falls within 10 percent of the certified value of the reference
gas. If the value measured by the Hg CEMS during the above span
linearity challenge exceeds +/-10 percent of the certified value of the
reference gas, the monitoring system must be evaluated and repaired and
a new ``above span linearity'' challenge met before returning the Hg
CEMS to service, or data above span from the Hg CEMS must be subject to
the quality assurance procedures established in paragraph (k)(2)(iii)
of this section. In this manner values measured by the Hg CEMS during
the above span linearity challenge exceeding +/-20 percent of the
certified value of the reference gas must be normalized using Equation
22.
    (iii) Quality assure any data above the span value established in
paragraph (k)(1) of this section using the following procedure. Any
time two consecutive one-hour average measured concentrations of Hg
exceeds the span

value you must, within 24 hours before or after, introduce a higher,
``above span'' Hg reference gas standard to the Hg CEMS. The ``above
span'' reference gas must meet the requirements of PS 12A, Section 7.1,
must target a concentration level between 50 and 150 percent of the
highest expected hourly concentration measured during the period of
measurements above span, and must be introduced at the probe. While
this target represents a desired concentration range that is not always
achievable in practice, it is expected that the intent to meet this
range is demonstrated by the value of the reference gas. Expected
values may include ``above span'' calibrations done before or after the
above span measurement period. Record and report the results of this
procedure as you would for a daily calibration. The ``above span''
calibration is successful if the value measured by the Hg CEMS is
within 20 percent of the certified value of the reference gas. If the
value measured by the Hg CEMS exceeds 20 percent of the certified value
of the reference gas, then you must normalize the one-hour average
stack gas values measured above the span during the 24-hour period
preceding or following the ``above span'' calibration for reporting
based on the Hg CEMS response to the reference gas as shown in equation
22:
[GRAPHIC] [TIFF OMITTED] TR27JY15.032

Only one ``above span'' calibration is needed per 24 hour period. If
the ``above span'' calibration is conducted during the period when
measured emissions are above span and there is a failure to collect at
least one valid data point in an hour due to the calibration duration,
then you must determine the emissions average for that missed hour as
the average of hourly averages for the hour preceding the missed hour
and the hour following the missed hour. In an hour where an ``above
span'' calibration is being conducted and one or more data points are
collected, the emissions average is represented by the average of all
valid data points collected in that hour.
* * * * *
    (5) * * *
    (i) Develop a mercury hourly mass emissions rate by conducting
performance tests annually, within 11 to 13 calendar months after the
previous performance test, using Method 29, or Method 30B, to measure
the concentration of mercury in the gases exhausted from the alkali
bypass and coal mill.
* * * * *
    (iv) If mercury emissions from the coal mill and alkali bypass are
below the method detection limit for two consecutive annual performance
tests, you may reduce the frequency of the performance tests of coal
mills and alkali bypasses to once every 30 months. If the measured
mercury concentration exceeds the method detection limit, you must
revert to testing annually until two consecutive annual tests are below
the method detection limit.

    (l) HCl Monitoring Requirements. If you are subject to an emissions
limitation on HCl emissions in Sec.  63.1343, you must monitor HCl
emissions continuously according to paragraph (l)(1) or (2) and
paragraphs (m)(1) through (4) of this section or, if your kiln is
controlled using a wet or dry scrubber or tray tower, you alternatively
may parametrically monitor SO2 emissions continuously
according to paragraph (l)(3) of this section. You must also develop an
emissions monitoring plan in accordance with paragraphs (p)(1) through
(4) of this section.
    (1) If you monitor compliance with the HCl emissions limit by
operating an HCl CEMS, you must do so in accordance with Performance
Specification 15 (PS 15) of appendix B to part 60 of this chapter, or,
upon promulgation, in accordance with any other performance
specification for HCl CEMS in appendix B to part 60 of this chapter.
You must operate, maintain, and quality assure a HCl CEMS installed and
certified under PS 15 according to the quality assurance requirements
in Procedure 1 of appendix F to part 60 of this chapter except that the
Relative Accuracy Test Audit requirements of Procedure 1 must be
replaced with the validation requirements and criteria of sections
11.1.1 and 12.0 of PS 15. When promulgated, if you choose to install
and operate an HCl CEMS in accordance with PS 18 of appendix B to part
60 of this chapter, you must operate, maintain and quality assure the
HCl CEMS using the associated Procedure 6 of appendix F to part 60 of
this chapter. For any performance specification that you use, you must
use Method 321 of appendix A to part 63 of this chapter as the
reference test method for conducting relative accuracy testing. The
span value and calibration requirements in paragraphs (l)(1)(i) and
(ii) of this section apply to all HCl CEMS used under this subpart.
    (i) You must use a measurement span value for any HCl CEMS of 0-10
ppmvw unless the monitor is installed on a kiln without an inline raw
mill. Kilns without an inline raw mill may use a higher span value
sufficient to quantify all expected emissions concentrations. The HCl
CEMS data recorder output range must include the full range of expected
HCl concentration values which would include those expected during
``mill off'' conditions. The corresponding data recorder range shall be
documented in the site-specific monitoring plan and associated records.
    (ii) In order to quality assure data measured above the span value,
you must use one of the three options in paragraphs (l)(1)(ii)(A)
through (C) of this section.
    (A) Include a second span that encompasses the HCl emission
concentrations expected to be encountered during ``mill off''
conditions. This second span may be rounded to a multiple of 5 ppm of
total HCl. The requirements of the appropriate HCl monitor performance
specification shall be followed for this second span with the exception
that a RATA with the mill off is not required.
    (B) Quality assure any data above the span value by proving
instrument linearity beyond the span value established in paragraph
(l)(1)(i) of this section using the following procedure. Conduct a
weekly ``above span linearity'' calibration challenge of the monitoring
system using a reference gas with a certified value greater than your
highest expected hourly concentration or greater than 75 percent of the
highest measured hourly concentration. The ``above span'' reference gas
must meet the requirements of the applicable performance specification
and must be introduced to the measurement system at the probe. Record
and report the results of this procedure as you would for a daily
calibration. The ``above span

linearity'' challenge is successful if the value measured by the HCl
CEMS falls within 10 percent of the certified value of the reference
gas. If the value measured by the HCl CEMS during the above span
linearity challenge exceeds 10 percent of the certified value of the
reference gas, the monitoring system must be evaluated and repaired and
a new ``above span linearity'' challenge met before returning the HCl
CEMS to service, or data above span from the HCl CEMS must be subject
to the quality assurance procedures established in paragraph
(l)(1)(ii)(D) of this section. Any HCl CEMS above span linearity
challenge exceeding +/-20 percent of the certified value of the
reference gas requires that all above span data must be normalized
using Equation 23.
    (C) Quality assure any data above the span value established in
paragraph (l)(1)(i) of this section using the following procedure. Any
time two consecutive one-hour average measured concentration of HCl
exceeds the span value you must, within 24 hours before or after,
introduce a higher, ``above span'' HCl reference gas standard to the
HCl CEMS. The ``above span'' reference gas must meet the requirements
of the applicable performance specification and target a concentration
level between 50 and 150 percent of the highest expected hourly
concentration measured during the period of measurements above span,
and must be introduced at the probe. While this target represents a
desired concentration range that is not always achievable in practice,
it is expected that the intent to meet this range is demonstrated by
the value of the reference gas. Expected values may include above span
calibrations done before or after the above-span measurement period.
Record and report the results of this procedure as you would for a
daily calibration. The ``above span'' calibration is successful if the
value measured by the HCl CEMS is within 20 percent of the certified
value of the reference gas. If the value measured by the HCl CEMS is
not within 20 percent of the certified value of the reference gas, then
you must normalize the stack gas values measured above span as
described in paragraph (l)(1)(ii)(D) of this section. If the ``above
span'' calibration is conducted during the period when measured
emissions are above span and there is a failure to collect at least one
valid data point in an hour due to the calibration duration, then you
must determine the emissions average for that missed hour as the
average of hourly averages for the hour preceding the missed hour and
the hour following the missed hour. In an hour where an ``above span''
calibration is being conducted and one or more data points are
collected, the emissions average is represented by the average of all
valid data points collected in that hour.
    (D) In the event that the ``above span'' calibration is not
successful (i.e., the HCl CEMS measured value is not within 20 percent
of the certified value of the reference gas), then you must normalize
the one-hour average stack gas values measured above the span during
the 24-hour period preceding or following the `above span' calibration
for reporting based on the HCl CEMS response to the reference gas as
shown in Equation 23:
[GRAPHIC] [TIFF OMITTED] TR27JY15.033

Only one ``above span'' calibration is needed per 24-hour period.
    (2) Install, operate, and maintain a CMS to monitor wet scrubber or
tray tower parameters, as specified in paragraphs (m)(5) and (7) of
this section, and dry scrubber, as specified in paragraph (m)(9) of
this section.
    (3) If the source is equipped with a wet or dry scrubber or tray
tower, and you choose to monitor SO2 emissions, monitor
SO2 emissions continuously according to the requirements of
Sec.  60.63(e) and (f) of part 60 subpart F of this chapter. If
SO2 levels increase above the 30-day rolling average
SO2 operating limit established during your performance
test, you must:
    (i) As soon as possible but no later than 48 hours after you exceed
the established SO2 value conduct an inspection and take
corrective action to return the SO2 emissions to within the
operating limit; and
    (ii) Within 60 days of the exceedance or at the time of the next
compliance test, whichever comes first, conduct an HCl emissions
compliance test to determine compliance with the HCl emissions limit
and to verify or re-establish the SO2 CEMS operating limit.
* * * * *
    (n) Continuous Flow Rate Monitoring System. You must install,
operate, calibrate, and maintain instruments, according to the
requirements in paragraphs (n)(1) through (10) of this section, for
continuously measuring and recording the stack gas flow rate to allow
determination of the pollutant mass emissions rate to the atmosphere
from sources subject to an emissions limitation that has a pounds per
ton of clinker unit and that is required to be monitored by a CEMS.
    (1) You must install each sensor of the flow rate monitoring system
in a location that provides representative measurement of the exhaust
gas flow rate at the sampling location of the mercury CEMS, taking into
account the manufacturer's recommendations. The flow rate sensor is
that portion of the system that senses the volumetric flow rate and
generates an output proportional to that flow rate.
* * * * *
    (4) The flow rate monitoring system must be equipped with a data
acquisition and recording system that is capable of recording values
over the entire range specified in paragraph (n)(2) of this section.
* * * * *
    (o) Alternate monitoring requirements approval. You may submit an
application to the Administrator for approval of alternate monitoring
requirements to demonstrate compliance with the emission standards of
this subpart subject to the provisions of paragraphs (o)(1) through (6)
of this section.
* * * * *
    (3) You must submit the application for approval of alternate
monitoring requirements no later than the notification of performance
test. The application must contain the information specified in
paragraphs (o)(3)(i) through (iii) of this section:

Sec.  63.1354  Reporting requirements.

* * * * *
    (b) * * *

    (9) The owner or operator shall submit a summary report
semiannually to the EPA via the Compliance and Emissions Data Reporting
Interface (CEDRI). (CEDRI can be accessed through the EPA's Central
Data Exchange (CDX) (www.epa.gov/cdx).) You must use the appropriate
electronic report in CEDRI for this subpart. Instead of using the
electronic report in CEDRI for this subpart, you may submit an
alternate electronic file consistent with the extensible markup
language (XML) schema listed on the CEDRI Web site (http://www.epa.gov/ttn/chief/cedri/index.html), once the XML schema is available. If the
reporting form specific to this subpart is not available in CEDRI at
the time that the report is due, you must submit the report the
Administrator at the appropriate address listed in Sec.  63.13. You
must begin submitting reports via CEDRI no later than 90 days after the
form becomes available in CEDRI. The reports must be submitted by the
deadline specified in this subpart, regardless of the method in which
the reports are submitted. The report must contain the information
specified in Sec.  63.10(e)(3)(vi). In addition, the summary report
shall include:
    (i) All exceedances of maximum control device inlet gas temperature
limits specified in Sec.  63.1346(a) and (b);
    (ii) Notification of any failure to calibrate thermocouples and
other temperature sensors as required under Sec.  63.1350(g)(1)(iii) of
this subpart; and
    (iii) Notification of any failure to maintain the activated carbon
injection rate, and the activated carbon injection carrier gas flow
rate or pressure drop, as applicable, as required under Sec.
63.1346(c)(2).
    (iv) Notification of failure to conduct any combustion system
component inspections conducted within the reporting period as required
under Sec.  63.1347(a)(3).
    (v) Any and all failures to comply with any provision of the
operation and maintenance plan developed in accordance with Sec.
63.1347(a).
    (vi) For each PM CPMS, HCl, Hg, and THC CEMS, D/F temperature
monitoring system, or Hg sorbent trap monitoring system, within 60 days
after the reporting periods, you must report all of the calculated 30-
operating day rolling average values derived from the CPMS, CEMS, CMS,
or Hg sorbent trap monitoring systems.
* * * * *
    (viii) Within 60 days after the date of completing each CEMS
performance evaluation test as defined in Sec.  63.2, you must submit
relative accuracy test audit (RATA) data to the EPA's CDX by using
CEDRI in accordance with paragraph (b)(9) of this section. Only RATA
pollutants that can be documented with the ERT (as listed on the ERT
Web site) are subject to this requirement. For any performance
evaluations with no corresponding RATA pollutants listed on the ERT Web
site, you must submit the results of the performance evaluation to the
Administrator at the appropriate address listed in Sec.  63.13.
    (ix) For PM performance test reports used to set a PM CPMS
operating limit, the electronic submission of the test report must also
include the make and model of the PM CPMS instrument, serial number of
the instrument, analytical principle of the instrument (e.g. beta
attenuation), span of the instruments primary analytical range,
milliamp value equivalent to the instrument zero output, technique by
which this zero value was determined, and the average milliamp signals
corresponding to each PM compliance test run.
    (x) All reports required by this subpart not subject to the
requirements in paragraphs (b)(9) introductory text and (b)(9)(viii) of
this section must be sent to the Administrator at the appropriate
address listed in Sec.  63.13. The Administrator or the delegated
authority may request a report in any form suitable for the specific
case (e.g., by commonly used electronic media such as Excel
spreadsheet, on CD or hard copy). The Administrator retains the right
to require submittal of reports subject to paragraph (b)(9)
introductory text and (b)(9)(viii) of this section in paper format.
