**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


### 44773 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Rules and Regulations

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.

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


### 44774 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Rules and Regulations

1 These issues are further discussed in the docket, via communication with John Holmes dated September 24, 2014. 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 (SO 2 ) 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 SO 2 CEMS signal to the HCl concentration (corrected to 7 percent oxygen). The operating limit would be established at a point where the SO 2 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 SO 2 controls preferentially remove HCl, an increase

in SO 2 emissions would not indicate an increase in HCl emissions as long as

some SO 2 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 ° 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.

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.

as well as incorrect dates and crossreferences. 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/lawsregulations/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.


### 44776 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Rules and Regulations

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). List of Subjects

(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.

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.

■ 3. Section 60.62 is amended by adding paragraphs (a)(1)(i), (a)(2), (b)(1)(iii) and (iv), revising paragraph (d), and adding paragraph (e) to read as follows:

**§ 60.62 Standards.**

(a) * * * (1) * * * (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:

**§ 60.63 Monitoring of operations.**

* * * * *

(c) * * * (1) For each kiln or clinker cooler subject to a PM emissions limit in §§ 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.

Where:

X 1 = The PM CPMS data points for the three runs constituting the performance test,

Y 1 = 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.

Where: R = The relative lb/ton clinker per milliamp or digital equivalent for your PM CPMS. Y 1 = The three run average PM lb/ton clinker.


### 44778 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Rules and Regulations

X 1 = 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.

Where:

O l = 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.

Where:

X 1 = The PM CPMS data points for all runs

i. n = The number of data points.

O h = 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.

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.

**§ 63.1341 Definitions.**

* * * * *


### 44779 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Rules and Regulations

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:

**§ 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.

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

**§ 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


### 44782 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Rules and Regulations

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.

Where:

X 1 = The PM CPMS data points for the three runs constituting the performance test.

Y 1 = 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.

Where: R = The relative lb/ton-clinker per milliamp or digital equivalent for your PM CPMS.

Y 1 = The three run average lb/ton-clinker PM

concentration.

X 1 = 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.

Where:

(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.

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.

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.

Where:

E Cm = Combined hourly emission rate of PM from the kiln and bypass stack and/or inline coal mill, lb/ton of kiln clinker production.

E K = Hourly emissions of PM emissions from the kiln, lb.

(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.

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.

(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 § 63.1346(b),

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 § 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 § 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 § 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 § 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:

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 § 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 § 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 § 63.1350(k)(5).

C i = Concentration of mercury for operating hour i, mg/scm. Q

i = Volumetric flow rate of effluent gas for operating hour i, where C i and Q i are on the same basis (either wet or dry), scm/
hr. k = Conversion factor, 1 lb/454,000,000 mg. 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 § 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 § 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 § 63.1350(l)(1). See § 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 § 63.1350(l).

(iii) As an alternative to paragraph (b)(6)(i)(B) of this section, you may
choose to monitor SO 2 emissions using
a CEMS in accordance with the requirements of § 63.1350(l)(3). You
must establish an SO 2 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:

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


### 44785 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Rules and Regulations

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 § 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 § 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.

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.

Where:

T l = The 30-day operating limit for your THC CEMS, ppmvw.

Y 1 = The average organic HAP concentration from Eq. 12, ppmvd.

X 1 = 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.

T h = 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.

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

Use Equation 16 to determine the 30 kiln operating day

average.

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

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 SO 2 Monitoring. If you choose to monitor

SO 2 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 § 63.1350(l)(3). You
must establish an SO 2 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 § 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 forHCl, you must also determine a sitespecific SO 2 emissions limit by operating an SO 2 CEMS in accordance with the requirements of § 63.1350(l). The duration of the performance test must be three hours and the average SO 2 concentration (as calculated from the average output) during the 3-hour test
must be calculated. You must establish your SO 2 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 SO 2 levels measured during raw mill on and raw mill off testing.

(iv) Your SO 2 CEMS must be calibrated and operated according to the requirements of § 60.63(f).

(v) Your SO 2 CEMS measurement scale must be capable of reading SO 2 concentrations consistent with the requirements of § 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.

¥ 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 SO 2 CEMS signal to your HCl concentration corrected to 7 percent O 2 by using the

SO 2 CEMS instrument zero, the average

SO 2 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.

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


### 44789 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Rules and Regulations

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:

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 § 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 SO 2 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


### 44790 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Rules and Regulations

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:

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 SO 2 emissions,

monitor SO 2 emissions continuously according to the requirements of § 60.63(e) and (f) of part 60 subpart F of this chapter. If SO 2 levels increase above the 30-day rolling average SO 2 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 SO 2 value conduct an inspection and take corrective action to
return the SO 2 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 reestablish the SO 2 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:

* * * * *

### 44791 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Rules and Regulations

(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 § 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 § 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 § 63.1346(a) and (b);

(ii) Notification of any failure to calibrate thermocouples and other temperature sensors as required under § 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 § 63.1346(c)(2).

(iv) Notification of failure to conduct any combustion system component inspections conducted within the reporting period as required under § 63.1347(a)(3).

(v) Any and all failures to comply with any provision of the operation and maintenance plan developed in accordance with § 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 § 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 § 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 § 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.
