Mercury and Air Toxics Standards (MATS) Completion of Electronic 
Reporting Requirements

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is proposing to 
amend the electronic reporting requirements for the National Emission 
Standards for Hazardous Air Pollutants: Coal- and Oil-Fired electric 
utility steam generating units (also known as the Mercury and Air 
Toxics Standards (MATS)). This proposed rule would revise and 
streamline the electronic data reporting requirements of MATS (both for 
owners or operators of electric utility steam generating units (EGUs) 
who use performance stack testing and EGU owners or operators who use 
continuous monitoring to demonstrate compliance) and would increase 
data transparency. EGU owners or operators would use one familiar 
electronic reporting system, instead of two separate systems, reducing 
their burden. In addition, the public and regulatory authorities would 
have enhanced access to MATS data. Finally, no new continuous 
monitoring requirements are proposed by this action. Overall, this 
proposed rule would serve to ease burden, increase MATS data flow and 
usage, make it easier for inspectors and auditors to assess compliance, 
and encourage wider use of continuous emissions monitoring systems 
(CEMS) for MATS compliance.

I. Why is the EPA issuing this proposed rule?

    The EPA is issuing this proposed rule to streamline the electronic 
data reporting requirements in MATS; to increase data transparency by 
making more of the MATS data available in Extensible Markup Language 
(XML) format; to amend the reporting and recordkeeping requirements 
associated with performance stack tests, particulate matter (PM) and 
hydrogen chloride (HCl) CEMS, and PM continuous parameter monitoring 
systems (CPMS); and to make minor clarifications and corrections to the 
mercury (Hg) and HCl monitoring provisions, which were brought to our 
attention following publication of the MATS Technical Correction Rule 
(see 81 FR 20172, April 6, 2016).
    These proposed amendments would revise the recordkeeping and 
reporting requirements of MATS, in response to concerns raised by the 
regulated community. Section 63.10031 of the original MATS required 
affected EGU owners or operators to report MATS emissions and 
compliance information electronically using two data systems (see 77 FR 
9304, February 16, 2012). Paragraph (a) of Sec.  63.10031 required 
those EGU owners or operators who demonstrate compliance by 
continuously monitoring Hg and/or HCl and/or hydrogen fluoride (HF) 
emissions to use the Emissions Collection and Monitoring Plan System 
(ECMPS) Client Tool to submit monitoring plan information, quality 
assurance test results, and hourly emissions data in accordance with 
appendices A and B to subpart UUUUU of 40 CFR part 63. Paragraph (f) of 
Sec.  63.10031 required performance stack test results, performance 
evaluations of Hg, HCl, HF, sulfur dioxide (SO2), and PM 
CEMS, 30-boiler operating day rolling average values for certain 
parameters, notifications of compliance status, and semiannual 
compliance reports to be submitted to the EPA's WebFIRE database via 
the Compliance and Emissions Data Reporting Interface (CEDRI).
    Subsequent to the publication of MATS, stakeholders suggested to 
the EPA that the electronic reporting burden of MATS could be 
significantly reduced if all of the required information were reported 
to one data system instead of two. The stakeholders also suggested that 
using one data system would benefit the EPA and the public in their 
review of MATS data, because the information would be reported in a 
consistent format. In view of these considerations, the stakeholders 
urged the EPA to consider amending the MATS rule to require all of the 
data to be reported through the ECMPS, a familiar data system that most 
EGU owners or operators have been using since 2009 to meet the 
electronic reporting requirements of the Acid Rain Program.
    After careful consideration of the stakeholders' recommendations, 
the EPA concluded that the increased transparency of the emissions data 
and the reduction in reporting burden that could be achieved through 
the use of a single data system are consistent with Agency priorities. 
As a result, late in 2014 the EPA decided to take the necessary steps 
to require all of the electronic reports required by MATS to be 
submitted through the ECMPS Client Tool. Those steps would include 
revising MATS, modifying the ECMPS Client Tool, creating a detailed set 
of reporting instructions, and beta testing the modified software. 
Recognizing that insufficient time was available to complete these 
tasks before the initial compliance date for MATS (April 16, 2015), the 
Agency embarked on a two-phased approach to complete them.
    The first phase has been completed. The EPA published a final rule 
requiring EGU owners or operators to suspend temporarily (until April 
16, 2017) the use of the CEDRI interface as the means of submitting the 
reports described in Sec.  63.10031(f) introductory text, (f)(1), 
(f)(2), and (f)(4). Instead, EGU owners or operators must use the ECMPS 
Client Tool to submit Portable Document Format (PDF) versions of these 
reports on an interim basis (see 80 FR 15510, March 24, 2015). The 
specific reports to be submitted in PDF format include: Performance 
stack test reports which must contain enough information to assess 
compliance and to demonstrate that the testing was done properly (e.g., 
such information as would be provided by the Electronic Reporting Tool 
(ERT); relative accuracy test audit (RATA) reports for SO2, 
HCl, HF, and Hg CEMS; RATA reports for Hg sorbent trap monitoring 
systems; response correlation audit (RCA) and relative response audit 
(RRA) reports for PM CEMS; 30-boiler operating day rolling average 
reports for PM CEMS, PM CPMS, and approved hazardous air pollutants 
(HAP) metals CEMS; Notifications of Compliance Status; and semiannual 
compliance reports. Section 63.10031(f)(6) of the March 24, 2015, final 
rule requires each PDF version of a submitted interim report to include 
information that identifies the facility (name and address), the EGU(s) 
to which the report applies, the applicable rule citation, and other 
information. The rule further specifies that in the event that 
implementation of the single data system initiative cannot be completed 
by April 16, 2017, the electronic reporting of MATS data will revert to 
the original two systems approach on and after that date.
    In the preamble to the March 24, 2015, final rule, the EPA outlined 
the second phase of the single data system initiative, which would be 
executed during the interim PDF reporting period. In phase two: (1) The 
Agency would publish a direct final rule, requiring MATS-affected 
sources to use the ECMPS Client Tool to submit all required reports in 
a structured XML format with specific data elements for each type of 
report; and (2) a detailed set of reporting instructions would be 
developed and ECMPS would be modified accordingly, in order to receive 
and process the data.
    The EPA has been working diligently to compile the required data 
elements, to develop reporting instructions, and to prepare program 
modifications; however, after considering the magnitude of the rule 
changes that would be required to execute phase two, coupled with the 
need to specify data elements to be reported electronically for PM 
CEMS, PM CPMS, and HCl CEMS, the EPA expects that some stakeholders 
will want to have an opportunity to review and provide comment on these 
proposed changes. Therefore, the EPA concluded that in this instance 
notice and comment rulemaking involving both a proposed rule and a 
final rule is a better approach than a direct final rulemaking.

No. EPA-HQ-OAR-2009-0234.

C. What is the scope of these proposed amendments?

    This proposed rule would extend the interim PDF reporting process 
described in Sec.  63.10031(f) from April 16, 2017, to December 31, 
2017. In addition, this proposed rule would amend the reporting 
requirements in Sec.  63.10031 of the MATS regulation, and, for 
consistency with those changes, would amend related texts in Sec. Sec.  
63.10011, 63.10021, and 63.10032, and in Tables 3, 8, and 9 to 40 CFR 
part 63, subpart UUUUU. The recordkeeping and reporting sections of 
appendix B would be amended \1\ and three new appendices would be added 
to the rule, i.e., appendices C, D, and E. The interim PDF format 
reporting period would be extended in order to finalize this proposed 
rule and to complete modifications to the ECMPS Client Tool, to develop 
reporting instructions, and to allow data acquisition and handling 
system vendors to adapt to the changes.
---------------------------------------------------------------------------

    \1\ The EPA has recently published a technology-neutral 
performance specification and associated quality assurance (QA) test 
procedures for HCl monitors (see Performance Specification 18 (PS 
18) and Quality Assurance Procedure 6 (Procedure 6) in 80 FR 38628, 
July 7, 2015). This proposed rule would add recordkeeping and 
electronic reporting requirements for sources electing to monitor 
HCl according to PS 18 and Procedure 6.
---------------------------------------------------------------------------

    While the changes in this proposed rule will take time to 
implement, no significant impact on stakeholders is expected. The set 
of data elements for performance stack tests and continuous monitoring 
system (CMS) performance evaluations would remain unchanged; only the 
reporting format and mechanism would change. Rather than requiring 
submission of these data via CEDRI, EGU owners or operators would use 
the ECMPS Client Tool to report in XML format, generated either by 
using the ERT or by other appropriate means.
    In addition to reporting the MATS data through the ECMPS Client 
Tool, EGU owners or operators would be required to use the ECMPS to 
report hourly data and quality assurance test results for PM CEMS and 
hourly response data for PM CPMS in XML format (if those compliance 
options were selected) and to provide quarterly, rather than 
semiannual, compliance reporting.
    This proposed rule would reduce the excess emissions reporting 
requirements for all instrumental monitoring except PM CPMS. Instead of 
reporting only excess emissions, EGU owners or operators would be 
required to report all of the 30- (or 90-) boiler operating day rolling 
average emission rates on a quarterly basis for EGUs that use CEMS or 
sorbent trap monitoring systems to demonstrate compliance with MATS. 
This represents a shift away from exception-only reporting to 
continuous compliance reporting.
    As previously noted, new HCl CEMS reporting and recordkeeping 
requirements would be added to appendix B for the certification and QA 
tests required by PS 18 and QA Procedure 6. These proposed requirements 
are not expected to increase the burden because multiple compliance 
options are available for demonstrating compliance with HCl emission 
limits (e.g., HCl quarterly stack testing or HCl monitoring using 
Fourier Transform Infrared (FTIR) CEMS in accordance with PS 15, and 
SO2 monitoring as a surrogate for HCl). Therefore, if EGU 
owners or operators anticipate that implementing PS 18 and Procedure 6 
as a means of demonstrating compliance determination is too burdensome, 
other existing compliance determination approaches may be used.

D. What is the purpose of these proposed amendments?

    These amendments are being proposed to revise and streamline the 
electronic reporting requirements of MATS; to increase transparency of 
MATS emissions data; to reduce the reporting burden via the use of a 
single reporting system; to amend the reporting requirements for PM 
CEMS, PM CPMS, Hg CEMS, and Hg sorbent trap monitoring systems; to 
specify the recordkeeping and reporting requirements associated with 
the use of PS 18 and Procedure 6 for HCl CEMS; and to make minor 
clarifications and corrections to the HCl and Hg monitoring provisions.

E. What specific amendments to subpart UUUUU would be made by this 
proposed rule?

    The proposed amendments are discussed in detail in the paragraphs 
below.
1. Proposed Revisions to Reporting Requirements in Sec.  63.10031
    The reporting section of MATS, i.e., Sec.  63.10031, would be 
amended as follows:
    (a) ECMPS would be designated as the exclusive data system for MATS 
reporting.
    (b) The interim PDF reporting process described in Sec.  
63.10031(f) would end on

[[Page 67065]]

December 31, 2017, to allow for an orderly transition away from the 
interim process at a calendar year boundary. Compliance with the 
emissions and operating limits during the interim period would be 
assessed based on the various PDF report submittals, Notifications of 
Compliance Status, and the data from Hg, HCl, HF, or SO2 
CEMS or Hg continuous sorbent trap monitoring reported through the 
ECMPS Client Tool (see Sec.  63.10031(e)(1)).
    (c) Although the interim PDF reporting process described in Sec.  
63.10031(f) would be discontinued as of December 31, 2017, in order to 
properly close out that process, PDF submittals would still be accepted 
for reports required under paragraph (f) introductory text, (f)(1), 
(f)(2), or (f)(4) if the deadlines for submitting those reports extend 
beyond that date. As an example, the last semiannual report to use the 
interim PDF reporting process would be the report covering the period 
July 1 to December 31, 2017; such a report would be due by January 31, 
2018.
    (d) Revised paragraph (f)(2) would require quarterly reporting of 
all 30- or 90-boiler operating day rolling average emission rates for 
units monitoring Hg, HCl, HF, and/or SO2 emissions, and for 
units using emissions averaging, starting with a report covering the 
first quarter of 2018. This change would be consistent with the 
requirement in Sec.  63.10031(f)(2) of the current rule for quarterly 
reporting of 30-boiler operating day rolling averages for EGUs using PM 
CEMS, PM CPMS, and approved HAP metals CEMS.
    (e) Until the interim reporting period ends on December 31, 2017, 
the 30-boiler operating day rolling averages for PM CEMS, PM CPMS, and 
approved HAP metals CEMS would continue to be reported quarterly in PDF 
format, in accordance with Sec.  63.10031(f)(2). Then, starting with 
the first quarter of 2018, the 30- or 90-boiler operating day rolling 
averages for all parameters (including Hg, HF, HCl, and SO2) 
would be reported in XML format in quarterly compliance reports, as 
discussed in section II.E.1.j of this preamble, below.
    (f) Paragraphs (a)(1), (2), and (5) in revised Sec.  63.10031 of 
this proposed rule would clarify the electronic reporting requirements 
for the Hg, HCl, HF, SO2, and auxiliary CMS. Specifically:
    (i) Paragraph (a)(1) would require the electronic reporting 
requirements of appendix A to be met if Hg CEMS or sorbent trap 
monitoring systems are used.
    (ii) Paragraph (a)(2) would require the electronic reporting 
requirements of appendix B to be met, with one important qualification, 
if HCl or HF monitoring systems are used. Until January 1, 2018, if PS 
18 in part 60, appendix B, is used to certify an HCl monitor and 
Procedure 6 in part 60, appendix F, is used for on-going QA of the 
monitor, EGU owners or operators would report temporarily only data 
that the existing programming of ECMPS is able to accommodate, i.e., 
hourly HCl emissions data and the results of daily calibration drift 
tests and RATAs; records would be kept of all of the other required 
certification and QA tests and supporting data. The reason for this 
temporary, limited reporting is that PS 18 and Procedure 6 were not 
published until July 7, 2015; therefore, it was not possible to specify 
recordkeeping and reporting requirements for them in the original 
version of appendix B. Now that PS 18 and Procedure 6 have been 
finalized, this proposed rule would add the necessary recordkeeping and 
reporting requirements, and the interim reporting for HCl would be 
discontinued as of December 31, 2017 (for further discussion, see 
section II.E.4 of this preamble).
    (iii) Paragraph (a)(5) would clarify the electronic reporting 
requirements for the SO2 CEMS and the auxiliary monitoring 
systems.
    (iv) Paragraph (f)(3) would be removed and reserved for consistency 
with the changes described in items (i) through (iii), immediately 
above.
    (g) Paragraphs (b)(2) and (4) would be revised to remove references 
to postmark dates for submittal of semiannual compliance reports; these 
reports currently are, and would continue to be, submitted 
electronically through ECMPS in PDF format.
    (h) The provision in paragraph (b)(5) which would allow affected 
EGU owners or operators to follow alternate submission schedules for 
semiannual compliance reports would be removed. The uniform submission 
schedule described in Sec.  63.10031(b)(1)-(4) would be required for 
all affected EGUs, so that compliance with this reporting requirement 
can easily be tracked.
    (i) Revised paragraph (b)(5) would further require EGU owners or 
operators to discontinue submission of semiannual compliance reports 
when the interim PDF reporting period ends; the final semi-annual 
report would cover the period from July 1 through December 31, 2017.
    (j) EGU owners or operators would submit quarterly compliance 
reports in lieu of the semiannual reports, starting with reports 
covering the first calendar quarter of 2018 (see Sec.  63.10031(g)). 
The quarterly compliance reports plus attachments would consolidate 
other reports that were originally required to be submitted separately 
on different time tracks, i.e., performance stack test results and 
quarterly reports of 30- and 90-boiler operating day rolling averages. 
The quarterly compliance reports would be due within 60 days after the 
end of each calendar quarter; we believe that this allows sufficient 
time to receive the results of tests performed at or near the end of 
the quarter. Each quarterly compliance report submitted would include 
the applicable data elements listed in sections 2 through 13 of 
proposed appendix E to subpart UUUUU of 40 CFR part 63.
    The operator's MATS compliance strategy would determine which 
appendix E data elements would be included in each quarterly compliance 
report. If continuous emission monitoring is used to demonstrate 
compliance on a 30-boiler operating day rolling average basis, the 
quarterly compliance report would include all of the 30-day averages 
calculated during the quarter. If emissions averaging is used, EGU 
owners or operators would report all of the 30- or 90-group boiler 
operating day weighted average emission rates (WAERs) calculated during 
the quarter. If periodic stack testing for compliance is performed 
(including 30-boiler operating day Hg Low Emitting Electric Utility 
Steam Generating Unit (LEE) tests), the EGU owner or operator would 
report a summary of each test completed during the calendar quarter and 
indicate whether the test has a special purpose (i.e., if it were to be 
used to establish LEE status or for emissions averaging).
    Note that for all cases in which the EPA reference methods 
supported by the ERT are used to perform particular stack tests, the 
EGU owner or operator would be required to provide the data elements 
specific to the test method(s) used, in XML format, as an attachment to 
the compliance report. The data elements common to all tests and 
specific data elements for the various reference methods are listed in 
sections 17 through 21 of proposed appendix E. This information is 
already required by MATS, just in another format, and is essential for 
ensuring that performance tests are conducted properly; confirming the 
reported values; and developing emission factors, as well as other 
Agency purposes.
    The quarterly compliance reports would retain and incorporate the 
following features of the semiannual compliance reports: (1) The date 
of the last boiler tune-up; (2) the date of the last burner inspection; 
(3) monthly fuel usage data; (4) malfunction information;

[[Page 67066]]

(5) reporting of deviations; and (6) emergency bypass information.
    The quarterly compliance reports move away from traditional excess 
emissions reporting for those EGU owners or operators who choose to use 
Hg, SO2, HF, or HCl CEMS or sorbent trap monitoring systems 
to demonstrate compliance. Currently, those EGU owners or operators 
must provide the excess emissions and monitor downtime data described 
in Sec.  63.10(e)(3)(v) and (vi) in PDF format as part of their 
semiannual compliance reports. The information to be reported includes, 
among other things, identification of excess emissions periods, 
identification of periods when the monitoring was inoperative or out of 
control, the reasons for the excess emission and monitor downtime 
periods, the nature and cause of any malfunctions, corrective actions 
or preventative measures taken, description of repairs or adjustments 
to inoperative or out-of-control CMS, the total amount of EGU operating 
time in the reporting period, and the excess emissions and monitor 
downtime percentages. As explained above, the proposed amendments 
would, instead, require all of the 30- (or 90-) boiler operating day 
rolling averages or WAERs to be included in the quarterly reports. 
Note, however, that some excess emissions information would still be 
included in the compliance reports. Specifically, the proposed 
revisions to Sec.  63.10031(d) would require reporting of the range of 
dates and the cause (if known) of each excess emission, as defined in 
Sec.  63.10042, and any corrective actions taken. For Hg, HCl, HF, PM, 
and SO2 CEMS and for sorbent trap monitoring systems and PM 
CPMS, the percent monitor availability (PMA) at the end of the quarter 
and the lowest hourly PMA recorded during the quarter would also be 
reported. All CMS except for PM CPMS would be subject to these revised 
excess emissions reporting requirements, which would take effect in 
2018. EGU owners or operators using PM CPMS would continue to report 
the information in Sec.  63.10(e)(v) and (vi) in PDF format, as an 
attachment to the quarterly compliance report.
    Finally, if an EGU relies on paragraph (2) of the definition of 
startup given in Sec.  63.10042, the information in Sec.  63.10020(e), 
which is referenced in Sec.  63.10031(c)(5), would be reported 
quarterly in PDF format, as an attachment to the compliance report. 
Note that the EPA understands that reporting this startup data in PDF 
format is not as transparent and user-friendly as it could be; 
therefore, we solicit comment on whether this information should be 
made more transparent and user-friendly. If so, we request comment on 
possible techniques to achieve those ends, e.g., by requiring the data 
to be submitted in XML format.
    We believe that consolidating information in quarterly compliance 
reports as described above, rather than requiring separate submittals 
of stack test results, 30- (or 90-) boiler operating day rolling 
average compliance reports, and semiannual reports that come in 
separately at different times during the year, would greatly simplify 
reporting and make it easier for inspectors and auditors to assess 
compliance with the standards. Also, quarterly, as opposed to 
semiannual, reporting would be advantageous because it would shorten 
significantly the interval between the time that a deviation or excess 
emission occurs and the time that the regulatory authority is made 
aware of the deviation or excess emission. Draft reporting instructions 
for the quarterly compliance reports are provided in the rule docket 
and on the Clean Air Markets Division (CAMD) Web site, for 
consideration.
    (k) The requirements in Sec.  63.10031(f)(1) and (6) to submit PDF 
reports of Hg, HCl, HF, and SO2 RATAs, and RRAs and RCAs of 
PM CEMS would be discontinued for tests completed after December 31, 
2017. For RATAs, RRAs and RCAs completed on or after January 1, 2018, 
the ECMPS Client Tool would be used to report the test results, as 
required under appendix A and/or B and/or C and/or 40 CFR part 75. The 
ECMPS Client Tool would also be used to attach the XML and PDF files 
that contain the applicable data elements and other information from 
sections 17 through 22 of proposed appendix E, which provide details of 
the reference method(s) used for each test, along with the electronic 
test results.
    (l) Note that one additional PDF submittal would be required prior 
to January 1, 2018, and several other PDF submittals would still be 
required on and after January 1, 2018. Specifically, the following 
information would have to be provided in PDF format:
    (i) A detailed report of the PS 11 correlation test, if the EGU 
owner or operator elected to use a certified PM CEMS to monitor PM 
emissions continuously, and recording valid data from the CEMS had 
begun prior to January 1, 2018. This report is due no later than 
December 31, 2017;
    (ii) Any Notifications of Compliance Status issued on or after 
January 1, 2018;
    (iii) The excess emissions summary report described in Sec.  
63.10(e)(3)(v) and (vi), if the EGU owner or operator elected to 
demonstrate compliance using a PM CPMS. As previously noted, this 
report would be submitted as an attachment to the quarterly compliance 
report.
    (iv) For EGUs relying on paragraph (2) of the definition of startup 
given in Sec.  63.10042, the parametric data and other information in 
Sec.  63.10020(e), for startup and shutdown incidents. This information 
is currently provided in PDF format as part of the semiannual 
compliance report. As previously noted, starting with a report covering 
the first quarter of 2018, the data would be submitted as an attachment 
to the quarterly compliance report.
    (v) For each test described in sections 14.1 through 14.3 of 
proposed appendix E, section 22 of appendix E would require the EGU 
owner or operator to provide additional information that is ordinarily 
included in test reports, but is incompatible with electronic 
reporting, such as diagrams showing the location of the test site and 
the sampling points, laboratory calibrations of source sampling 
equipment, calibration gas cylinder certificates, stack testers' 
credentials, etc. For performance stack tests, this information would 
be provided as an attachment to the quarterly compliance report. For 
RATAs, RRAs, RCAs, and PM CEMS correlations, the information would be 
provided along with the electronic (XML) test summary required under 
appendix A, B, C, or part 75 for SO2 RATAs.
    (m) To accommodate the required PDF reports, the applicable data 
elements in Sec.  63.10031(f)(6)(i) through (xii) would be entered into 
the ECMPS Client Tool at the time of submission of each PDF file.
    (n) Regarding performance stack test submittals, this proposed 
rule, as explained in item (j) above, would require a summary of the 
test results to be included in the quarterly compliance report, with 
detailed information about the reference method(s) used as an 
attachment to the quarterly report, in XML format. Similarly, the QA 
test submittals described in item (k) above would require an electronic 
summary of the test results to be generated, accompanied by a separate 
XML file that includes detailed information about the reference 
method(s) used. As proposed, the ECMPS Client Tool would be used to 
submit all of this information to the EPA, although ECMPS would not 
evaluate the detailed reference method information. Instead, those data 
would be transmitted directly to the Central Data Exchange where they 
could be further processed and evaluated. ECMPS would, however, perform

[[Page 67067]]

electronic checking of the summarized RATA, RRA, and RCA results in a 
manner that is consistent with the way that QA test results are checked 
under the Acid Rain Program, and ECMPS would use the results of those 
evaluations for its assessment of the quality-assured status of the 
hourly Hg, HCl, HF, SO2, or PM emissions data. In 
addition, ECMPS would perform basic checks of the information in the 
quarterly compliance reports, e.g., checking for completeness and 
proper formatting, but would leave compliance assessment to others. The 
EPA intends for these data submissions to work together in a 
complimentary fashion to enable meaningful compliance determinations. 
It would be essential for any problems with the data that are 
identified by the reviewers to be communicated to all involved and 
resolved appropriately. For example, if, for a particular RATA, a 
review of the detailed reference method data shows that the reference 
method was not done properly, the RATA would be invalidated. This would 
necessitate invalidation of the hourly emissions data until a valid 
RATA was performed and passed, which would require resubmission of one 
or more quarterly emissions reports, recalculation of 30-day compliance 
averages, and possibly resubmission of a quarterly compliance report.
    (o) Note that the existing ERT can produce a single XML file that 
includes all of the detailed reference method information necessary for 
the stack test and QA test reports described above. Therefore, there 
are two ways that the XML file could be generated that meet the 
reference method data submission requirements in sections 17-21 of 
appendix E; either use the ERT itself or another program that provides 
the data in an appropriate XML file format. In view of this, we solicit 
comment on whether submitting the detailed reference method data to 
ECMPS will actually reduce the reporting burden on EGU owners or 
operators, or whether submitting the data directly to CEDRI would be 
preferable.
2. Proposed Revisions to Rule Texts Associated With Reporting 
Requirements in Sec.  63.10031
    The proposed revisions to Sec.  63.10031 necessitate changes to 
other sections of the rule to ensure that the rule is internally 
consistent. The affected rule sections are as follows:
    (a) Revised Sec.  63.10011(e) would require Notifications of 
Compliance Status for the initial and subsequent compliance 
demonstrations to be submitted in accordance with Sec.  63.10030(e) and 
Sec.  63.10031(f)(4) and proposed Sec.  63.10031(h). This change is 
necessary to include all initial and subsequent compliance 
demonstration submissions. Both the interim reporting process described 
in Sec.  63.10031(f)(4) and the proposed on-going reporting requirement 
in Sec.  63.10031(h) require these Notifications to be submitted in PDF 
format, through ECMPS.
    (b) Section 63.10011(g)(3), Sec.  63.10021(h)(3) and (i), and three 
sentences in Table 3 to subpart UUUUU of 40 CFR part 63 (in Items 3 and 
4) would be revised to be consistent with proposed Sec.  63.10031(i). 
For EGU owners or operators relying on paragraph (2) of the definition 
of startup in Sec.  63.10042, Sec.  63.10031(i) would retain the 
requirement for the parametric data and other information referenced in 
Sec.  63.10031(c)(5) to be included in the semiannual compliance 
reports, in PDF format, for startup and shutdown incidents that occur 
during the interim reporting period. However, in view of the proposed 
phase-out of the semiannual compliance reports, for startup and 
shutdown incidents that occur during each subsequent calendar quarter, 
starting with the first quarter of 2018, the information referenced in 
Sec.  63.10031(c)(5) would be provided as a PDF attachment to the 
quarterly compliance report, due within 60 days after the end of the 
quarter.
    (c) References to the EPA's ERT and the CEDRI interface would be 
removed from Sec.  63.10021(f) and replaced with a general statement 
requiring all applicable notifications and reports to be submitted 
through ECMPS.
    (d) The introductory text of Sec.  63.10032(a) would be amended to 
include references to the recordkeeping required under proposed 
appendices C (for PM CEMS), D (for PM CPMS), and E (for the quarterly 
compliance reports, reference method test data elements, and other 
information). Also, in view of the move away from semiannual compliance 
reporting to quarterly reporting, the term ``semiannual compliance 
report'' in paragraph (a)(1) would be replaced with the more generic 
term ``compliance report.''
    (e) Table 8 to subpart UUUUU of 40 CFR part 63 would be revised to 
be consistent with the amendments to Sec.  63.10031 and the proposed 
addition of appendices C, D, and E.
    (f) Finally, the recordkeeping requirement for excess emissions in 
the 28th row of Table 9 to subpart UUUUU of 40 CFR part 63, would be 
clarified.
3. Proposed Revisions to Appendix A
    This proposed rule would make two corrections to the Hg monitoring 
provisions of appendix A. First, in the MATS Technical Corrections rule 
package, which was published on April 6, 2016 (see 81 FR 20172, April 
6, 2016), there is language in section 4.1.1.5.2 of appendix A 
describing an alternate way to calculate and interpret RATA results 
when Hg emissions are less than 50 percent of the standard. This 
language was inadvertently carried over from the proposed rule and 
conflicts with the alternate relative accuracy specification in Table 
A-1 of the final rule. In view of this, we propose to delete that 
language. Second, at least one monitor vendor expressed confusion over 
an apparent inconsistency of the Hg RATA acceptance criteria in Table 
A-2 versus that in Table A-1. The vendor sought clarification of when 
the main 20-percent relative accuracy (RA) specification must be used 
and when the alternate specification applies. In Table A-2, it appears 
that the 20-percent RA specification only applies when the average CMS 
value (Cavg) is >=2.5 micrograms per standard cubic meter 
([micro]g/scm) while the 20-percent RA specification in Table A-1 may 
be applied at any reference method concentration level and the 
alternate specification applies only when the average reference method 
value is <2.5 [micro]g/scm. We acknowledge this inconsistency and 
propose to amend Table A-2 be consistent with Table A-1 and to clarify 
that the main RA specification may be applied at any concentration.
4. Proposed Revisions to Appendix B
    For affected sources desiring to continuously monitor HCl 
emissions, the original version of appendix B required the monitoring 
system to be certified according to PS 15 in appendix B to 40 CFR part 
60. However, PS 15 applies only to FTIR monitoring systems; therefore, 
the use of other viable HCl monitoring technologies was excluded. In 
view of this, the EPA regarded the requirement to use PS 15 exclusively 
as a temporary measure, until a technology-neutral performance 
specification for HCl monitors could be developed and published. In 
section 3.1 of appendix B, the Agency stated its intention to publish 
such a PS in the near future together with appropriate on-going QA 
requirements and to amend appendix B to accommodate their use. The 
required PS, (PS 18 in 40 CFR part 60, appendix B), and the on-going QA 
test requirements (Procedure 6 in 40 CFR part 60, appendix F) were 
published on July 7, 2015 (see 80 FR 38628, July 7, 2015).
    Now that technology-neutral certification and QA test requirements

[[Page 67068]]

for HCl monitors have been promulgated, EGU owners or operators are 
free to use any viable HCl monitoring technology that can meet the PS. 
However, in order for ECMPS to accommodate all of the required tests, 
additional time must be allotted for software development. In view of 
this, revised paragraph (a)(2) of Sec.  63.10031 would require only 
information that is compatible with the existing programming of ECMPS 
to be reported electronically through December 31, 2017; this includes 
hourly HCl emissions data and the results of daily calibration drift 
tests and RATAs. In the interim, EGU owners or operators would be 
required to keep records of all of the other certification and QA 
tests.
    This proposed rule would revise the title to section 2.3 of 
appendix B by deleting the reference to FTIR-only monitoring systems. 
In addition, this proposed rule would amend the recordkeeping and 
reporting sections of appendix B (i.e., sections 10 and 11) by 
specifying the data elements that must be recorded and reported 
electronically for each of the tests required by PS 18 and Procedure 6. 
The proposed revisions make a clear distinction between the tests 
required for FTIR monitors that are following PS 15 and the test 
requirements of PS 18 and Procedure 6. Some of the tests in PS 18 and 
Procedure 6 are similar to tests for which ECMPS programming exists. 
For example, the ``measurement error test'' required for initial 
certification of the HCl monitor is structurally the same as a 40 CFR 
part 75 linearity check. However, other tests have no counterpart in 40 
CFR part 75 CEMS requirements and will require special software 
development and reporting instructions. EGU owners or operators would 
report RATAs of the HCl CEMS that are completed on and after January 1, 
2018, and the applicable data elements in proposed appendix E in XML 
format for each test run, along with the electronic summary of results 
required under section 11 of appendix B. EGU owners or operators would 
also provide the information required in section 22 of proposed 
appendix E in PDF format for each RATA.
    Because a technology-neutral PS for HCl CEMS was not available 
prior to April 16, 2015 (which was the compliance date for many of the 
existing EGUs), EGU owners or operators interested in monitoring HCl 
either had to use an FTIR system and follow PS 15 or implement another 
compliance option (e.g., quarterly emission testing) while awaiting 
publication of PS 18 and Procedure 6. In light of this, the EPA 
proposes to revise and restructure section 11.5.1 of appendix B to 
clarify when electronic reporting of hourly HCl emissions data begins. 
There are two possibilities. In the first case, the monitor would be 
used for the initial compliance demonstration. This could either apply 
to a certified FTIR monitor following PS 15 or to a certified monitor 
following PS 18, if the owner or operator of the EGU received an 
extension for the compliance date. In this case, EGU owners or 
operators would begin reporting hourly HCl emissions through ECMPS with 
the first operating hour of the initial compliance demonstration. In 
the second case, another option, such as stack testing, would be used 
for the initial compliance demonstration and continuous monitoring 
would be implemented later on. In that case, EGU owners or operators 
would begin reporting hourly HCl emissions reporting through ECMPS with 
the first operating hour after successfully completing all required 
certification tests of the CEMS. In either case, the first required 
quarterly emissions report would be for the calendar quarter in which 
emissions reporting begins.
5. Proposed Addition of Appendix C
    A new appendix, i.e., appendix C, would be added to subpart UUUUU 
of part 63. Appendix C sets forth the continuous monitoring and 
reporting requirements for filterable PM. Appendix C is structurally 
similar to appendices A and B, but there are certain notable 
differences. Appendix C includes provisions for installation and 
certification of the PM CEMS, and for on-going QA of the data from the 
CEMS. The monitoring system would be certified according to PS 11 in 40 
CFR part 60, appendix B, and for the on-going QA tests, Procedure 2 to 
40 CFR part 60, appendix F would be required. The proposed frequencies 
for the QA tests and the rules for data validation are presented in 
Section 5 of appendix C. Note that in contrast with appendices A and B, 
the familiar QA operating quarter and grace period scheme would not 
apply to the on-going QA tests of the PM CEMS. Also, for technical 
reasons, the use of temporary like-kind replacement PM analyzers and 
the conditional data validation provisions in Sec.  75.20(b)(3) would 
not be allowed. The proposed procedures for calculating the PM emission 
rates in units of the emission standard are found in section 6. These 
calculation methods are basically the same as those used for Hg 
monitoring systems and HCl and HF CEMS in appendices A and B. The 
proposed recordkeeping and reporting requirements are found in section 
7. Proposed section 7.1 specifies that monitoring plan records and 
hourly records of operating parameters, PM concentration, diluent gas 
concentration, stack gas flow rate and moisture content, and PM 
emission rate must be kept. Sections 7.2.3 and 7.2.4, respectively, 
would require monitoring plan information and the results of 
certification, recertification, and QA tests to be reported 
electronically. Proposed section 7.2.5 requires quarterly electronic 
emissions reports to be submitted within 30 days after the end of each 
calendar quarter. All electronic reports would be submitted using the 
ECMPS Client Tool. However, electronic reporting of monitoring plan 
information, certification and on-going QA test results would not begin 
until January 1, 2018, to allow time for software development and beta 
testing. Until then, records of the required information and tests 
would be kept. For PM CEMS correlations, RRAs, and RCAs completed on 
and after January 1, 2018, the applicable reference method data 
elements in sections 17 through 21 of proposed appendix E would be 
reported in XML format for each test run, along with the electronic 
test summary required under section 7.2.4 of proposed appendix C. The 
information required in section 22 of proposed appendix E would also be 
provided in PDF format for each test. Reporting of hourly PM emissions 
data would begin either with the first operating hour after December 
31, 2017, or the first operating hour after completion of the initial 
PM CEMS correlation test, whichever is later.
6. Proposed Addition of Appendix D
    A second new appendix, i.e., appendix D, would be added to subpart 
UUUUU of 40 CFR part 63. Appendix D sets forth the monitoring and 
reporting requirements for EGU owners or operators who elect to use a 
PM CPMS to demonstrate continuous compliance. Structurally, appendix D 
is similar to appendices A, B, and C, but it is much simpler. The 
criteria for system design and performance, the procedures for 
determining operating limits, data reduction, and compliance 
assessment, and certain recordkeeping requirements are not detailed in 
the appendix; rather, the applicable sections of the MATS rule are 
cross-referenced (see proposed sections 2.1 through 2.4, 3.1 
introductory text, and section 3.1.1.1 of the appendix).
    Proposed section 3.1.1.2 requires the ECMPS Client Tool to be used 
to create and maintain an electronic monitoring plan. The PM CPMS would 
be defined as a monitoring system with a unique

[[Page 67069]]

system ID number. The monitoring plan would also include the current 
operating limit (with units of measure), the make, model, and serial 
number of the PM CPMS, the analytical principle of the monitoring 
system and monitor span and range information.
    Operating parameter records would be required for each hour of 
operation of the affected EGUs, including the date and hour, the EGU or 
stack operating time, and a flag to identify exempt startup and 
shutdown hours. Hourly average PM CPMS output values would be reported 
for each hour in which a valid value of the output parameter is 
obtained, in units of milliamps, PM concentration, or other units of 
measure, including the instrument's digital signal output equivalent. A 
special code would be required to indicate operating hours in which 
valid data are not obtained. The percent monitor data availability 
would also be calculated according to Sec.  75.32.
    Proposed sections 3.2.2 and 3.2.3, respectively, require 
notifications (to be provided in accordance with Sec.  63.10030) and 
electronic monitoring plan submittals at specified times. Proposed 
section 3.2.4 requires electronic quarterly reports to be submitted 
within 30 days after the end of each calendar quarter. Reporting of 
hourly responses from the PM CPMS would begin either with the first 
operating hour in the first calendar quarter of 2018 or the first 
operating hour after completion of the initial stack test that 
establishes the operating limit, whichever is later. Each quarterly 
report would include a compliance certification with a statement by a 
responsible official that to the best of his or her knowledge, the 
report is true, accurate, and complete. In addition to the electronic 
quarterly reports, proposed section 3.2.5 requires the results of each 
performance stack test for PM that is used to establish an operating 
limit to be reported electronically in the relevant quarterly 
compliance report, in accordance with Sec.  63.10031(g). For PM tests 
completed on and after January 1, 2018, the data elements common to all 
tests in section 17 of proposed appendix E and the applicable reference 
method data elements (in sections 18-20) would be provided for each 
test run, in an XML report. This report would be submitted along with 
the quarterly compliance report. The additional information required in 
section 22 of proposed appendix E would also be reported for each test 
in PDF format as an attachment to the compliance report.
7. Proposed Addition of Appendix E
    A third new appendix, i.e., appendix E, would be added to subpart 
UUUUU of 40 CFR part 63. Sections 2 through 13 of proposed appendix E 
list the data elements that must be reported in XML format in the 
quarterly compliance reports that cover the period beginning January 1, 
2018, and are required under proposed Sec.  63.10031(g).
    The MATS compliance strategy (e.g., whether the EGU owner or 
operator elects to perform periodic stack testing, continuous 
monitoring, or to use emissions averaging) would determine which data 
elements must be reported. As previously noted, draft reporting 
instructions for the quarterly compliance reports are found in the rule 
docket and on the CAMD Web site.
    For each performance stack test that is completed on or after 
January 1, 2018 (including 30- or 90-boiler operating day Hg LEE 
tests), the data elements common to all tests in section 17 of proposed 
appendix E and the applicable reference method data elements (in 
sections 18-21) would be provided for each test run in an XML format. 
This report would be submitted along with the compliance report for the 
calendar quarter in which the test was completed.
    For RATAs, PM CEMS correlations, RRAs, and RCAs that are completed 
on or after January 1, 2018, the data elements common to all tests in 
section 17 of proposed appendix E and the applicable reference method 
data elements (in sections 17-21) would be provided for each test run 
in an XML report. This report would be submitted along with the 
electronic test results reported under appendix A (for Hg system 
RATAs), appendix B (for HCl and HF system RATAs), appendix C (for 
correlation tests, RRAs, and RCAs of a PM CEMS), and/or 40 CFR part 75 
(for SO2 system RATAs).
    The information in section 22 of proposed appendix E would also be 
provided for each performance stack test, RATA, RRA, RCA, and PM CEMS 
correlation, in PDF format.

F. What are the incremental costs and benefits of this proposed action?

    As mentioned below, while this proposed rulemaking would increase 
the frequency of compliance reports from semiannual to quarterly, the 
implementation of a single reporting system and consolidation of 
reporting would reduce the overall burden by at least 43,194 hours (per 
year) relative to the original rule. The estimated burden reduction 
would result in savings to regulated entities of $4,229,162 in 
annualized capital or operation and maintenance costs.

III. 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 Office of Management and Budget (OMB) for 
review.

B. Paperwork Reduction Act (PRA)

    The information collection activities in this proposed rule have 
been submitted for approval to the OMB under the PRA. The Information 
Collection Request (ICR) document that the EPA prepared has been 
assigned EPA ICR number 2137.06. You can find a copy of the ICR in the 
docket for this proposed rule, and it is briefly summarized here.
    This action would not impose any additional information collection 
burden. Rather, it would reduce burden by requiring all of the 
essential data to be submitted to a single data system, rather than two 
systems, as was originally required. As previously discussed in this 
preamble, this proposed rule represents the second phase of a two-
phased approach to achieve that objective. This action would streamline 
MATS reporting by consolidating a number of separate reports that are 
currently submitted on different time tracks into a single, quarterly 
compliance submittal. It would also increase data transparency and 
provide the public and regulatory authorities with access to more of 
the MATS data in XML format. No new continuous monitoring requirements 
would be imposed by this proposed action. Coal-fired EGUs that do not 
qualify for LEE status would still be required to continuous monitor Hg 
emissions. The use of continuous monitoring would remain optional for 
all other parameters. The following is an example of how this proposed 
rule would streamline MATS reporting and reduce burden. Under the 
original rule, an owner or operator of a coal-fired EGU that elected: 
(1) To monitor PM and Hg continuously via CEMS; and (2) to perform 
quarterly HCl stack tests would have been required, for a typical 
calendar year, to submit four separate quarterly reports that include 
the 30-boiler operating day rolling averages for

[[Page 67070]]

PM, four more quarterly stack test reports for HCl, two separate RATA 
reports for Hg and HCl, and two semiannual compliance reports, for a 
total of 12 reports. These reports would all have been submitted on 
different time tracks. In contrast, this proposed rule would require 
only six reports for the same compliance strategy, i.e., four quarterly 
compliance report submittals and two RATA reports; data giving details 
of the reference methods used for the stack tests and RATAs would be 
provided along with each of these reports. The 30-boiler operating day 
rolling PM averages would be included in the quarterly compliance 
reports, together with the summarized HCl stack test results.
    Confidentiality: Any information submitted to the Agency for which 
a claim of confidentiality is made will be safeguarded according to the 
Agency policies set forth in title 40, chapter 1, part 2, subpart B--
Confidentiality of Business Information (see 40 CFR part 2; 41 FR 
36902, September 1, 1976; amended by 43 FR 40000, December 8, 1978; 43 
FR 42251, September 20, 1978; 44 FR 17674, March 23, 1979).
    Respondents/affected entities: The respondents are owners or 
operators of fossil fuel-fired EGUs. The United States Standard 
Industrial Classification code for respondents affected by the rule is 
4911 (Electric Services). The corresponding North American Industry 
Classification System (NAICS) code is 221100 (Electric Power 
Generation, Transmission, and Distribution).
    Respondent's obligation to respond: The respondents are obliged to 
respond to the applicable recordkeeping and reporting requirements of 
the MATS.
    Estimated number of respondents: On average, over the next 3 years, 
approximately 1,252 existing respondents will be subject to the MATS 
emissions standards. It is estimated that an additional two respondents 
per year will also become subject. Therefore, the overall number of 
respondents expected in each of the next 3 years is 1,254.
    Frequency of response: Respondents would be required to submit 
quarterly compliance reports using a single electronic data system 
(i.e., ECMPS). This represents a change from the requirement to report 
semiannual compliance reports. The total annual response associated 
with this change would increase from 2,648 to 5,186. However, as 
illustrated in the example above, this increase in the number of annual 
responses would be offset to a great degree by requiring other reports 
that were originally required to be submitted separately to be 
incorporated into, or submitted together with, the quarterly compliance 
reports.
    Total estimated burden: Although this proposed rulemaking increases 
the frequency of compliance reports from semiannual to quarterly, the 
implementation of a single reporting system and consolidation of 
reporting is estimated to reduce the overall burden by at least 43,194 
hours (per year) relative to the original rule which required regulated 
entities to submit compliance data through 2 separate electronic 
systems in a piecemeal fashion. The estimated reduction in burden is 
based principally on the assumption that each quarterly compliance 
submittal required approximately 30 hours to prepare, which is 45 hours 
less than the original estimate for preparing a semiannual compliance 
report. Burden is defined at 5 CFR 1320.3(b).
    Total estimated cost: The reduction in burden associated with this 
proposed rulemaking would result in savings to regulated entities of 
$4,229,162 in annualized capital or operation and maintenance costs.
    An agency may not conduct or sponsor, and a person is not required 
to respond to a collection of information unless it displays a 
currently valid OMB control number. The OMB control numbers for the 
EPA's regulations in 40 CFR are listed in 40 CFR part 9.
    Submit your comments on the Agency's need for this information, the 
accuracy of the provided burden estimates, and any suggested methods 
for minimizing respondent burden to the EPA using the docket identified 
at the beginning of this proposed rule. You may also send your ICR-
related comments to OMB's Office of Information and Regulatory Affairs 
via email to [email protected], Attention: Desk Officer for 
the EPA. Since OMB is required to make a decision concerning the ICR 
between 30 and 60 days after receipt, OMB must receive comments no 
later than October 31, 2016. The EPA will respond to any ICR-related 
comments in the final rule.

C. Regulatory Flexibility Act (RFA)

    I certify that this proposed action will not have a significant 
economic impact on a substantial number of small entities under the 
RFA. This action will not impose any requirements on small entities.
    The RFA generally requires an agency to prepare a regulatory 
flexibility analysis of any rule subject to notice and comment 
rulemaking requirements under the Administrative Procedure Act or any 
other statute unless the agency certifies that the rule will not have a 
significant economic impact on a substantial number of small entities. 
Small entities include small businesses, small organizations, and small 
governmental jurisdictions. For purposes of assessing the impact of 
this final action on small entities, small entity is defined as: (1) A 
small business that is an electric utility producing 4 billion 
kilowatt-hours or less as defined by NAICS codes 221122 (fossil fuel-
fired electric utility steam generating units) and 921150 (fossil fuel-
fired electric utility steam generating units in Indian country); (2) a 
small governmental jurisdiction that is a government of a city, county, 
town, school district, or special district with a population of less 
than 50,000; and (3) a small organization that is any not-for-profit 
enterprise which is independently owned and operated and is not 
dominant in its field. In determining whether a rule has a significant 
economic impact on a substantial number of small entities, the impact 
of concern is any significant adverse economic impact on small 
entities, since the primary purpose of the regulatory flexibility 
analyses is to identify and address regulatory alternatives ``which 
minimize any significant economic impact of the rule on small 
entities.'' 5 U.S.C. 603 and 604. Thus, 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, or 
otherwise has a positive economic effect on all of the small entities 
subject to the rule. This proposed rule will not impose any 
requirements on small entities, and no small entities are expected to 
incur annualized costs as a result of the amendments. We have 
determined that the amendments will not result in any ``significant'' 
adverse economic impact for small entities. These proposed amendments 
would not create any new requirements or burdens, and no costs to small 
entities would be associated with these proposed amendments.

D. Unfunded Mandates Reform Act (UMRA)

    This action does not contain an unfunded mandate of $100 million or 
more as described in UMRA, 2 U.S.C. 1531-1538, and does not 
significantly or uniquely affect small governments. The action imposes 
no enforceable duty on any state, local or tribal governments or the 
private sector.

E. Executive Order 13132: Federalism

    This proposed action does not have federalism implications. It will 
not have substantial direct effects on the states,

[[Page 67071]]

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 proposed action does not have tribal implications as specified 
in Executive Order 13175. The proposed amendments would impose no 
requirements on tribal governments. Thus, Executive Order 13175 does 
not apply to this proposed action.

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

    The EPA interprets Executive Order 13045 as applying only to those 
regulatory actions that concern environmental health or safety risks 
that the EPA has reason to believe may disproportionately affect 
children, per the definition of ``covered regulatory action'' in 
section 2-202 of the Executive Order. This proposed action is not 
subject to Executive Order 13045 because it does not concern an 
environmental health risk or safety risk.

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

    This proposed 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

    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 that this proposed action does not have 
disproportionately high and adverse human health or environmental 
effects on minority populations, low-income populations, and/or 
indigenous peoples, as specified in Executive Order 12898 (59 FR 7629, 
February 16, 1994).

    The revisions and additions read as follows:


Sec.  63.10031  What reports must I submit and when?

    (a) You must submit each report in this section that applies to 
you.
    (1) If you are required to (or elect to) monitor Hg emissions 
continuously, you must meet the electronic reporting requirements of 
appendix A to this subpart.
    (2) If you elect to monitor HCl and/or HF emissions continuously, 
you must meet the electronic reporting requirements of appendix B to 
this subpart. Notwithstanding this requirement, if you opt to certify 
your

[[Page 67072]]

HCl monitor according to Performance Specification 18 in appendix B to 
part 60 of this chapter and to use Procedure 6 in appendix F to part 60 
of this chapter for on-going QA of the monitor, then, on and prior to 
December 31, 2017, report only hourly HCl emissions data and the 
results of daily calibration drift tests and RATAs performed prior to 
that date; keep records of all of the other required certification and 
QA tests.
    (3) If you elect to monitor filterable PM emissions continuously, 
you must meet the electronic reporting requirements of appendix C to 
this subpart. Electronic reporting of hourly PM emissions data shall 
begin with the later of: The first operating hour on or after January 
1, 2018; or the first operating hour after completion of the initial PM 
CEMS correlation test.
    (4) If you elect to demonstrate continuous compliance using a PM 
CPMS, you must meet the electronic reporting requirements of appendix D 
to this subpart. Electronic reporting of the hourly PM CPMS output 
shall begin with the later of: The first operating hour on or after 
January 1, 2018; or the first operating hour after completion of the 
initial performance stack test that establishes the operating limit for 
the PM CPMS.
    (5) If you elect to monitor SO2 emission rate 
continuously as a surrogate for HCl, you must use the ECMPS Client Tool 
to submit the following information to EPA (except where it is already 
required to be reported or has been previously provided under the Acid 
Rain Program or another emissions reduction program that requires the 
use of part 75 of this chapter):
    (i) Monitoring plan information for the SO2 CEMS and for 
any additional monitoring systems that are required to convert 
SO2 concentrations to units of the emission standard, in 
accordance with Sec. Sec.  75.62 and 75.64(a)(4) of this chapter;
    (ii) Certification, recertification, quality-assurance, and 
diagnostic test results for the SO2 CEMS and for any 
additional monitoring systems that are required to convert 
SO2 concentrations to units of the emission standard, in 
accordance with Sec.  75.64(a)(5) of this chapter; and
    (iii) Quarterly electronic emissions reports. You must submit an 
electronic quarterly report within 30 days after the end of each 
calendar quarter, starting with a report for the calendar quarter in 
which the initial 30 boiler operating day performance test begins. Each 
report must include the following information:
    (A) The applicable operating data specified in Sec.  75.57(b) of 
this chapter;
    (B) An hourly data stream for the unadjusted SO2 
concentration (in ppm), and separate unadjusted hourly data streams for 
the other parameters needed to convert the SO2 
concentrations to units of the standard. (Note: If a default moisture 
value is used in the emission rate calculations, an hourly data stream 
is not required for moisture; rather, the default value must be 
reported in the electronic monitoring plan);
    (C) An hourly SO2 emission rate data stream, in units of 
the standard (i.e., lb/mmBtu or lb/MWh, as applicable), calculated 
according to Sec.  63.10007(e) and (f)(1), rounded to 3 significant 
figures, and expressed in scientific notation;
    (D) The results of all required daily quality-assurance tests of 
the SO2 monitor and the additional monitors used to convert 
SO2 concentration to units of the standard, as specified in 
appendix B to part 75 of this chapter;
    (E) A compliance certification, which includes a statement, based 
on reasonable inquiry of those persons with primary responsibility for 
ensuring that all SO2 emissions from the affected EGUs under 
this subpart have been correctly and fully monitored, by a responsible 
official with that official's name, title, and signature, certifying 
that, to the best of his or her knowledge, the report is true, 
accurate, and complete. You must submit such a compliance certification 
statement in support of each quarterly report.
    (b) You must submit semiannual compliance reports according to the 
requirements in paragraphs (b)(1) through (5) of this section.
    (1) The first compliance report must cover the period beginning on 
the compliance date that is specified for your affected source in Sec.  
63.9984 or, if applicable, the extended compliance date approved under 
Sec.  63.6(i)(4), and ending on June 30 or December 31, whichever date 
is the first date that occurs at least 180 days after the compliance 
date that is specified for your affected source in Sec.  63.9984.
    (2) The first compliance report must be submitted electronically no 
later than July 31 or January 31, whichever date is the first date 
following the end of the first calendar half after the compliance date 
that is specified for your source in Sec.  63.9984 or, if applicable, 
the extended compliance date approved under Sec.  63.6(i)(4).
    (3) Each subsequent compliance report must cover the semiannual 
reporting period from January 1 through June 30 or the semiannual 
reporting period from July 1 through December 31.
    (4) Each subsequent compliance report must be submitted 
electronically no later than July 31 or January 31, whichever date is 
the first date following the end of the semiannual reporting period.
    (5) The final semiannual compliance report shall cover the 
reporting period from July 1, 2017 through December 31, 2017. Quarterly 
compliance reports shall be submitted thereafter, in accordance with 
paragraph (g) of this section, starting with a report covering the 
first calendar quarter of 2018.
    (c) * * *
    (5) * * *
    (iii) If you choose to use CEMS for compliance purposes, include 
hourly average CEMS values and hourly average flow rates. Use units of 
milligrams per cubic meter for PM CEMS, micrograms per cubic meter for 
Hg CEMS, and ppmv for HCl, HF, or SO2 CEMS. Use units of 
standard or actual cubic feet per hour on a wet basis for flow rates.
* * * * *
    (d)(1) Prior to January 1, 2018, in the semiannual compliance 
reports described in paragraph (c) of this section, you must include in 
the report the excess emissions and monitor downtime information 
required in Sec.  63.10(e)(3)(v) and (vi) for EGUs whose owners or 
operators rely on a CMS to comply with an emissions or operating limit.
    (2) Beginning on January 1, 2018, if you own or operate an EGU that 
relies on a CMS to demonstrate compliance, except as otherwise provided 
in paragraph (d)(3) of this section, you must include in your quarterly 
compliance report the following information for any excess emission(s) 
that occurred during the calendar quarter; if there were no excess 
emissions, you must include a statement to that effect in the 
compliance report:
    (i) The date (or, if applicable, the range of dates) on which each 
excess emission (as defined in Sec.  63.10042) occurred;
    (ii) The cause of the excess emission (if known);
    (iii) A description of any corrective actions taken; and
    (iv) If there were any malfunctions or emergency bypass incidents 
during the reporting period, include the number, duration, and a brief 
description of each type of malfunction or bypass event that occurred 
and that caused (or may have caused) any applicable emissions 
limitation to be exceeded.
    (3) If you rely on a PM CPMS to demonstrate compliance with an

[[Page 67073]]

operating limit, you must continue to provide the information in 
paragraph (d)(1) of this section as a quarterly PDF submittal, in 
accordance with paragraph (k) of this section.
    (e) Each affected source that has obtained a Title V operating 
permit pursuant to part 70 or part 71 of this chapter must report all 
deviations as defined in this subpart in the semiannual monitoring 
report required by 40 CFR 70.6(a)(3)(iii)(A) or 40 CFR 
71.6(a)(3)(iii)(A). If an affected source submits a semiannual 
compliance report pursuant paragraphs (c) and (d) of this section, or 
two quarterly compliance reports covering the appropriate calendar half 
pursuant to paragraph (g) of this section, along with, or as part of, 
the semiannual monitoring report required by 40 CFR 70.6(a)(3)(iii)(A) 
or 40 CFR 71.6(a)(3)(iii)(A), and the compliance report(s) includes all 
required information concerning deviations from any emission limit, 
operating limit, or work practice requirement in this subpart, 
submission of the compliance report(s) satisfies any obligation to 
report the same deviations in the semiannual monitoring report. 
Submission of the compliance report(s) does not otherwise affect any 
obligation the affected source may have to report deviations from 
permit requirements to the permit authority.
    (1) Prior to January 1, 2018, compliance with the emission limits 
and/or operating limits in this subpart shall be assessed based on 
information provided in the applicable reports and notifications 
described in paragraphs (a), (f), and (j) of this section.
    (2) On and after January 1, 2018, the interim PDF reporting period 
described in paragraph (f)(6) of this section shall be discontinued and 
compliance with the emissions and operating limits of this subpart 
shall be assessed based on information provided in:
    (i) The information described in paragraphs (g), (i), and (k) of 
this section;
    (ii) The applicable electronic reports required under paragraphs 
(a)(1) through (5) of this section; and
    (iii) Notifications of Compliance Status, in accordance with 
paragraph (h) of this section.
    (f) For each performance stack test completed prior to January 1, 
2018 (including 30-boiler operating day Hg LEE demonstration tests), 
you must submit a PDF test report in accordance with paragraph (f)(6) 
of this section, no later than 60 days after the date on which the 
testing is completed.
    (1) For each relative accuracy test audit (RATA) of an Hg, HCl, HF, 
or SO2 monitoring system completed prior to January 1, 2018, 
and for each relative response audit (RRA) and each response 
correlation audit (RCA) of a PM CEMS completed prior to that date, you 
must submit a PDF test report in accordance with paragraph (f)(6) of 
this section, no later than 60 days after the date on which the test is 
completed.
    (2) If, for a particular EGU or a group of EGUs serving a common 
stack, you have elected to demonstrate compliance using a PM CEMS, an 
approved HAP metals CEMS, or a PM CPMS, you must submit quarterly PDF 
reports in accordance with paragraph (f)(6) of this section, which 
include all of the 30-boiler operating day rolling average emission 
rates derived from the CEMS data or the 30-boiler operating day rolling 
average responses derived from the PM CPMS data (as applicable). Each 
quarterly report is due within 60 days after the reporting periods 
ending on March 31st, June 30th, September 30th, and December 31st. 
Submission of these quarterly reports in PDF format shall end with the 
report that covers the fourth calendar quarter of 2017. Beginning with 
the first calendar quarter of 2018, the compliance averages shall no 
longer be reported separately, but shall be incorporated into the 
quarterly compliance reports described in paragraph (g) of this 
section. In addition to the compliance averages for PM CEMS, PM CPMS, 
and/or HAP metals CEMS, the quarterly compliance reports described in 
paragraph (g) of this section must also include the rolling average 
emission rates for Hg, HCl, HF, and/or SO2, if you have 
elected to (or are required to) continuously monitor these pollutants. 
Further, if your EGU or common stack is in an averaging plan, your 
quarterly compliance reports must identify all of the EGUs or common 
stacks in the plan and must document the 30- or 90-group boiler 
operating day rolling weighted average emission rates (WAERs) for the 
averaging group.
    (3) [Reserved]
    (4) You must submit semiannual compliance reports as required under 
paragraphs (b) through (d) of this section, ending with a report 
covering the semiannual period from July 1 through December 31, 2017, 
and Notifications of Compliance Status as required under Sec.  
63.10030(e), in PDF format. Quarterly compliance reports shall be 
submitted in XML format thereafter, in accordance with paragraph (g) of 
this section, starting with a report covering the first calendar 
quarter of 2018.
* * * * *
    (6) All reports and notifications described in paragraphs (f) 
introductory text, (f)(1), (f)(2), and (f)(4) of this section shall be 
submitted to the EPA in the specified format and at the specified 
frequency using the ECMPS Client Tool. Each PDF version of a 
performance stack test report, CEMS RATA report, RRA report, and RCA 
report must include sufficient information to assess compliance and to 
demonstrate that the reference method testing was done properly. The 
following data elements must be entered into the ECMPS Client Tool at 
the time of submission of each PDF file:
* * * * *
    (vii) An indication of the type of PDF report or notification being 
submitted;
* * * * *
    (xi) The date the performance test was conducted (if applicable) 
and the test number (if applicable);
* * * * *
    (g) Starting with a report for the first calendar quarter of 2018, 
you must use the ECMPS Client Tool to submit quarterly electronic 
compliance reports. The compliance reports are due no later than 60 
days after the end of each calendar quarter. Each compliance report 
shall include the applicable data elements in sections 2 through 13 of 
appendix E to this subpart. For each performance stack test in the 
compliance report, provided that the testing was conducted using a 
method (or methods) supported by the ERT and identified on the ERT Web 
site, you must submit an XML file that includes the applicable data 
elements in sections 17 through 21 of appendix B to this subpart and a 
PDF attachment that includes the information in section 22 of appendix 
E to this subpart (see https://www3.epa.gov/ttn/chief/ert/ertinfo.pdf).
    (h) On and after January 1, 2018, all required Notifications of 
Compliance Status shall be submitted in accordance with Sec.  
63.9(h)(2)(ii), in PDF format, using the ECMPS Client Tool. The 
applicable data elements in paragraphs (f)(6)(i) through (xii) of this 
section must be entered into ECMPS with each Notification.
    (i) For startup and shutdown incidents that occur on or prior to 
December 31, 2017, you must include the information in Sec.  
63.10031(c)(5) in PDF format, in the semiannual compliance report. For 
startup and shutdown event(s) that occur on or after January 1, 2018, 
you must use the ECMPS Client Tool to submit this information in PDF 
format, as an attachment to each quarterly compliance report starting 
with the report for the first calendar quarter of 2018. The applicable 
data elements in

[[Page 67074]]

General Operation. The following provisions apply:
* * * * *

10. Recordkeeping Requirements

* * * * *
    10.1.8.1.1 For each required 7-day and daily calibration drift 
test or daily calibration error test (including daily calibration 
transfer standard tests) of the HCl or HF CEMS, record the test 
date(s) and time(s), reference gas value(s), monitor response(s), 
and calculated calibration drift or calibration error value(s). If 
you use the dynamic spiking option for the mid-level calibration 
drift check under PS-18, you must also record the measured 
concentration of the native HCl in the flue gas before and after the 
spike and the spiked gas dilution factor. When using an IP-CEMS 
under PS 18, you must also record the measured concentrations of the 
native HCl before and after introduction of each reference gas, the 
path lengths of the calibration cell and the stack optical path, the 
stack and calibration cell temperatures, the instrument line 
strength factor, and the calculated equivalent concentration of 
reference gas.
    10.1.8.1.2 For the required gas audits of an FTIR HCl or HF CEMS 
that is following PS 15, record the date and time of each spiked and 
unspiked sample, the audit gas reference values and uncertainties. 
Keep records of all calculations and data analyses required under 
sections 9.1 and 12.1 of Performance Specification 15, and the 
results of those calculations and analyses.
    10.1.8.1.3 For each required RATA of an HCl or HF CEMS, record 
the beginning and ending date and time of each test run, the 
reference method(s) used, and the reference method and HCl or HF 
CEMS run values. Keep records of stratification tests performed (if 
any), all the raw field data, relevant process operating data, and 
the all calculations used to determine the relative accuracy.
    10.1.8.1.4 For each required beam intensity test of an HCl IP-
CEMS under PS 18, record the test date and time, the known 
attenuation value (%) used for the test, the concentration of the 
high-level reference gas used, the full-beam and attenuated beam 
intensity levels, the measured HCl concentrations at full-beam 
intensity and attenuated intensity and the percent difference 
between them, and the results of the test. For each required daily 
beam intensity check of an IP-CEMS under Procedure 6, record the 
beam intensity measured including the units of measure and the 
results of the check.
    10.1.8.1.5 For each required measurement error test of an HCl 
monitor, record the date and time of each gas injection, the 
reference gas concentration (low, mid, or high) and the monitor 
response for each of the three injections at each of the three 
levels. Also record the average monitor response and the measurement 
error (ME) at each gas level and the related calculations. For 
measurement error tests conducted on IP-CEMS, also record the 
measured concentrations of the native HCl before and after 
introduction of each reference gas, the path lengths of the 
calibration cell and the stack optical path, the stack and 
calibration cell temperatures, the stack and calibration cell 
pressures, the instrument line strength factor, and the calculated 
equivalent concentration of reference gas.
    10.1.8.1.6 For each required level of detection (LOD) test of an 
HCl monitor performed in a controlled environment, record the test 
date, the concentrations of the reference gas and interference 
gases, the results of the seven (or more) consecutive measurements 
of HCl, the standard deviation, and the LOD value. For each required 
LOD test performed in the field, record the test date, the three 
measurements of the native source HCl concentration, the results of 
the three independent standard addition (SA) measurements known as 
standard addition response (SAR), the effective spike addition gas 
concentration (for IP-CEMS, the equivalent concentration of the 
reference gas), the resulting standard addition detection level 
(SADL) value and all related calculations. For extractive CEMS 
performing the SA using dynamic spiking, you must record the spiked 
gas dilution factor.
    10.1.8.1.7 For each required measurement error/level of 
detection response time test of an HCl monitor, record the test 
date, the native HCl concentration of the flue gas, the reference 
gas value, the stable reference gas readings, the upscale/downscale 
start and end times, and the results of the upscale and downscale 
stages of the test.
    10.1.8.1.8 For each required temperature or pressure measurement 
verification or audit of an IP-CEMS, keep records of the test date, 
the temperatures or pressures (as applicable) measured by the 
calibrated temperature or pressure reference device and the IP-CEMS, 
and the results of the test.
    10.1.8.1.9 For each required interference test of an HCl 
monitor, record the date of the test, the HCl concentration of the 
reference gas used, the concentrations of the interference test 
gases, the baseline HCl and HCl responses for each interferent 
combination spiked, and the total percent interference as a function 
of span or HCl concentration. Also keep records to document the 
quantity and quality of gases, gas volume/rate, temperature, and 
pressure used to conduct the test.
    10.1.8.1.10 For each quarterly relative accuracy audit (RAA) of 
an HCl monitor, record the beginning and ending date and time of

measured by the reference method and CEMS for each test run, the 
average concentrations measured by the reference method and the 
CEMS, and the calculated relative accuracy (RA). Keep records of the 
raw field data, relevant process operating data, and the 
calculations used to determine the RA.

HCl monitor, record the date and time of each injection, and the 
reference gas concentration (zero, mid, or high) and the monitor 
response for each injection. Also record the average monitor 
response and the calculated measurement error (ME) at each gas 
level. For IP-CEMS, you must also record the measured concentrations 
of the native HCl before and after introduction of each reference 
gas, the path lengths of the calibration cell and the stack optical 
path, the stack and calibration cell temperatures, the stack and 
calibration cell pressures, the instrument line strength factor, and 
the calculated equivalent concentration of reference gas.
    10.1.8.1.12 For each quarterly dynamic spiking audit (DSA) of an 
HCl monitor, record the date and time of the zero gas injection and 
each spike injection, the results of the zero gas injection, the gas 
concentrations (mid and high) and the dilution factors and the 
monitor response for each of the six upscale injections as well as 
the corresponding native HCl concentrations measured before and 
after each injection. Also record the average dynamic spiking error 
for each of the upscale gases, the calculated average DSA Accuracy 
at each upscale gas concentration, and all calculations leading to 
the DSA Accuracy.

11. Add appendix C to subpart UUUUU to read as follows:

Appendix C to Subpart UUUUU of Part 63--PM Monitoring Provisions

1. General Provisions

    1.1 Applicability. These monitoring provisions apply to the 
continuous measurement of filterable particulate matter (PM) 
emissions from affected EGUs under this subpart. A particulate 
matter continuous emission monitoring system (PM CEMS) is used 
together with other continuous monitoring systems and (as 
applicable) parametric measurement devices to quantify PM emissions 
in units of the applicable standard (i.e., lb/mmBtu or lb/MWh).
    1.2 Initial Certification and Recertification Procedures. You, 
as the owner or operator of an affected EGU that uses a PM CEMS to 
demonstrate compliance with a filterable PM emissions limit in Table 
1 or 2 to this subpart must comply with the initial certification 
and recertification procedures of Performance Specification 11 (PS 
11) in appendix B to part 60 of this chapter.
    1.3 Quality Assurance and Quality Control Requirements. You must 
meet the applicable quality assurance requirements of Procedure 2 in 
appendix F to part 60 of this chapter.
    1.4 Missing Data Procedures. You must not substitute data for 
missing data from the PM CEMS. Any process operating hour for which 
quality-assured PM concentration data are not obtained is counted as 
an hour of monitoring system downtime.
    1.5 Adjustments for Flow System Bias. When the PM emission rate 
is reported on a gross output basis, you must not adjust the data 
recorded by a stack gas flow rate monitor for bias, which may 
otherwise be required under Sec.  75.24 of this chapter.

2. Monitoring of PM Emissions

    2.1 Monitoring System Installation Requirements. Flue gases from 
the affected EGUs under this subpart vent to the atmosphere through 
a variety of exhaust configurations including single stacks, common 
stack configurations, and multiple stack configurations. For each of 
these configurations, Sec.  63.10010(a) specifies the appropriate 
location(s) at which to install continuous monitoring systems (CMS). 
These CMS installation provisions apply to the PM CEMS and to the 
other continuous monitoring systems and parametric monitoring 
devices that provide data for the PM emissions calculations in 
section 6 of this appendix.
    2.2 Primary and Backup Monitoring Systems. In the electronic 
monitoring plan described in section 7 of this appendix, you must 
create and designate a primary monitoring system for PM and for each 
additional parameter (i.e., stack gas flow rate, CO2 or 
O2 concentration, stack gas moisture content, as 
applicable). The primary system must be used to report hourly PM 
concentration values when the system is able to provide quality-
assured data, i.e., when the system is ``in control.'' However, to 
increase data availability in the event of a primary monitoring 
system outage, you may install, operate, maintain, and calibrate a 
redundant backup monitoring system. A redundant backup system is one 
that is permanently installed at the unit or stack location, and is 
kept on ``hot standby'' in case the primary monitoring system is 
unable to provide quality-assured data. You must represent each 
redundant backup system as a unique monitoring system in the 
electronic monitoring plan. You must certify each redundant backup 
monitoring system according to the applicable provisions in section 
4 of this appendix. In addition, each redundant monitoring system 
must meet the applicable on-going QA requirements in section 5 of 
this appendix.

3. PM Emissions Measurement Methods

    The following definitions, equipment specifications, procedures, 
and performance criteria are applicable
    3.1 Definitions. All definitions specified in section 3 of PS 11 
in appendix B to part 60 of this chapter and section 3 of Procedure 
2 in appendix F to part 60 of this chapter are applicable to the 
measurement of filterable PM emissions from electric utility steam 
generating units under this subpart.
    3.2 Continuous Monitoring Methods.
    3.2.1 Installation and Measurement Location. You must install 
the PM CEMS according to Sec.  63.10010 and section 2.4 of PS 11.
    3.2.2 Units of Measure. For the purposes of this subpart, you 
shall report hourly PM concentrations in the following units of 
measure:
    3.2.2.1 In both milligrams per actual cubic meter (mg/acm) and 
milligrams per wet standard cubic meter (mg/wscm) If the PM CEMS 
measures in units of mg/acm; or
    3.2.2.2 Milligrams per wet standard cubic meter (mg/wscm), if 
the PM CEMS measures in mg/wscm; or
    3.2.2.3 In both milligrams per dry standard cubic meter (mg/
dscm) and milligrams per wet standard cubic meter (mg/wscm), if the 
PM CEMS measures in units of mg/dscm.
    3.2.3 Other Necessary Data Collection. To convert hourly PM 
concentrations to the units of the applicable emissions standard 
(i.e., lb/mmBtu or lb/MWh), you must collect additional data as 
described in sections 3.2.3.1 and 3.2.3.2 of this appendix. You must 
install, certify, operate, maintain, and quality-assure any stack 
gas flow rate, CO2, O2, or moisture monitoring 
systems needed for this purpose according to sections 4 and 5 of 
this appendix. The calculation methods for the emission limits 
described in sections 3.2.3.1 and 3.2.3.2 of this appendix are 
presented in section 6 of this appendix.
    3.2.3.1 Heat Input-Based Emission Limits. To demonstrate 
compliance with a heat input-based PM emission limit in Table 2 to 
this subpart, you must provide the hourly stack gas CO2 
or O2 concentration, along with a fuel-specific 
Fc factor or dry-basis F-factor and (if applicable) the 
stack gas moisture content, in order to convert measured PM 
concentrations values to the units of the standard.
    3.2.3.2 Gross Output-Based Emission Limits. To demonstrate 
compliance with a gross output-based PM emission limit in Table 1 or 
Table 2 to this subpart, you must provide the hourly gross output, 
along with data from a certified stack gas flow rate monitor in 
order to convert measured PM concentrations values to units of the 
standard.

4. Certification and Recertification Requirements

    4.1 Certification Requirements. You must certify your PM CEMS 
and the other continuous monitoring systems used to determine 
compliance with the applicable emissions standard before the PM CEMS 
can be used to provide data under this subpart. Redundant backup 
monitoring systems (if used) are subject to the same certification 
requirements as the primary systems.
    4.1.1 PM CEMS. You must certify your PM CEMS according to PS 11 
in appendix B to part 60 of this chapter. PM CEMS that have been 
installed and certified according to PS 11 as a result of another 
state or federal regulatory requirement or consent decree prior to 
the effective date of this subpart shall be considered certified for 
this subpart if you can demonstrate that your PM CEMS meets the PS 
11 acceptance criteria based on the applicable emission standard in 
this subpart.
    4.1.2 Flow Rate, Diluent Gas, and Moisture Monitoring Systems. 
You must certify your continuous monitoring systems that are used to 
convert PM concentrations to units of the standard (i.e., stack gas 
flow rate,

[[Page 67079]]

diluent gas (CO2 or O2) concentration, or 
moisture monitoring systems) in accordance with the applicable 
provisions in Sec.  75.20 of this chapter and appendix A to part 75 
of this chapter.
    4.1.3 Other Parametric Measurement Devices. If data from 
temperature or pressure measurement devices are required to convert 
hourly PM concentrations to standard conditions, you must install, 
calibrate, maintain, and operate these devices according to the 
manufacturers' instructions.
    4.2 Recertification.
    4.2.1 You must recertify your PM CEMS if it is either: moved to 
a different stack or duct; moved to a new location within the same 
stack or duct; modified or repaired in such a way that the existing 
correlation is altered or impacted; or replaced.
    4.2.2 The flow rate, diluent gas, and moisture monitoring 
systems that are used to convert PM concentration to units of the 
emission standard are subject to the recertification provisions in 
Sec.  75.20(b) of this chapter.
    4.3 Development of a New or Revised Correlation Curve. You must 
develop a new or revised correlation curve if:
    4.3.1 A response correlation audit (RCA) is failed and the new 
or revised correlation is developed according to section 10.6 in 
Procedure 2 of appendix F to part 60 of this chapter; or
    4.3.2 The events described in paragraph (1) or (2) in section 
8.8 of PS 11 occur while the EGU is operating under normal 
conditions.

5. Ongoing Quality Assurance (QA) and Data Validation

    5.1 PM CEMS.
    5.1.1 Required QA Tests. Following initial certification, you 
must conduct periodic QA testing of each primary and (if applicable) 
redundant backup PM CEMS. The required QA tests and the performance 
specifications that must be met are found in Procedure 2 of appendix 
F to part 60 of this chapter.
    5.1.2 Out-of-Control Periods. Your PM CEMS is considered to be 
out-of-control, and you may not report data from it as quality-
assured, when the monitoring system malfunctions or when any 
acceptance criterion in PS 11 in appendix B to part 60 of this 
chapter or Procedure 2 in appendix F to part 60 of this chapter for 
the required QA tests is not met. Your PM CEMS is also considered to 
be out-of-control when a required QA test is not performed on 
schedule. When an out-of-control period occurs, you must take 
corrective actions (if necessary) and perform the appropriate 
follow-up calibrations and adjustments to bring the monitoring 
system back in-control. If the out-of-control period is triggered by 
a required QA test that is failed or not done on time, you must 
conduct the failed or late test and your PM CEMS must pass the test 
in order to end the out-of-control period. You must count out-of-
control periods of the PM CEMS as hours of monitoring system 
downtime.
    5.1.3 RCA and RRA Acceptability. The results of your RRA or RCA 
are considered acceptable provided that the criteria in section 
10.4(5) of Procedure 2 in appendix F to part 60 of this chapter are 
met for an RCA or section 10.4(6) of Procedure 2 in appendix F to 
part 60 of this chapter are met for an RRA.
    5.2 Stack Gas Flow Rate, Diluent Gas, and Moisture Monitoring 
Systems. The on-going QA test requirements and data validation 
criteria for the primary and (if applicable) redundant backup stack 
gas flow rate, diluent gas, and moisture monitoring systems are 
specified in appendix B to part 75 of this chapter.
    5.3 QA/QC Program Requirements. You must develop and implement a 
quality assurance/quality control (QA/QC) program for the PM CEMS 
and the other equipment that is used to provide data under this 
subpart. You may store your QA/QC plan electronically, provided that 
the information can be made available expeditiously in hard copy to 
auditors and inspectors.

maintenance log for this purpose. You must maintain the following 
records for each system or device: the date, time, and description 
of any testing, adjustment, repair, replacement, or preventive 
maintenance action performed, and records of any corrective actions 
taken. Additionally, you must record any adjustment that may 
significantly affect the ability of a monitoring system or 
measurement device to make accurate measurements, and you must keep 
a written explanation of the procedures used to make the 
adjustment(s).

    6.1.1 You must reduce the data from PM CEMS to hourly averages, 
in accordance with Sec.  60.13(h)(2) of this chapter.
    6.1.2 You must reduce all CEMS data from stack gas flow rate, 
CO2, O2, and moisture monitoring systems to 
hourly averages according to Sec.  75.10(d)(1) of this chapter.
    6.1.3 You must reduce all other data from devices used to 
convert readings from the PM CEMS to standard conditions to hourly 
averages according to Sec.  63.8(g)(2) or Sec.  75.10(d)(1) of this 
chapter. This includes, but is not limited to, data from devices 
used to measure temperature and pressure, or, for cogeneration units 
that calculate gross output based on steam characteristics, devices 
to measure steam flow rate, steam pressure, and steam temperature.
    6.1.4 Do not calculate the PM emission rate for any unit or 
stack operating hour in which valid data are not obtained for PM 
concentration or for a parameter used in the emissions calculations 
(i.e., gross output, stack gas flow rate, stack temperature, stack 
pressure, stack gas moisture content, or diluent gas concentration, 
as applicable).
    6.1.5 For the purposes of this appendix, part 75 substitute data 
values for stack gas flow rate, CO2 concentration, 
O2 concentration, and moisture content are not considered 
to be valid data.
    6.1.6 Operating hours in which PM concentration is missing or 
invalid are hours of monitoring system downtime. The use of 
substitute data for PM concentration is not allowed.
    6.1.7 You must exclude all data obtained during a boiler startup 
or shutdown operating hour (as defined in Sec.  63.10042) from the 
determination of the 30 boiler operating day rolling average PM 
emission rates.
    6.2 Calculation of PM Emission Rates. You must use the 
calculation methods in sections 6.2.1 through 6.2.3 of this appendix 
to convert measured PM concentration values to the units of the 
applicable emission standard.
    6.2.1 For each unit or stack operating hour, prior to converting 
the PM CEMS concentration to units of the emission

[[Page 67080]]

standard, if your PM CEMS measures the PM concentration in units of 
mg/acm, you must convert the PM CEMS concentration value to units of 
mg/wscm, using one of the following equations:
[GRAPHIC] [TIFF OMITTED] TP29SE16.021

Or
[GRAPHIC] [TIFF OMITTED] TP29SE16.002

Where:

Ch = PM concentration (mg/wscm)
Ca = PM concentration (mg/acm)
Ts = Stack Temperature ([deg]F)
TCEMS = CEMS Measurement Temperature ([deg]F)
PCEMS = CEMS Measurement Pressure (in. Hg)
Ps = Stack Pressure (in. Hg)
Tstd = Standard Temperature (68 [deg]F)
Pstd = Standard Pressure (29.92 in. Hg)

(Note: The hourly PM concentrations reported in ECMPS must be in 
units of mg/wscm. If your PM CEMS measures PM concentration in units 
of mg/m\3\ on a dry basis at standard conditions, you must apply a 
correction for the stack gas moisture content to convert it from mg/
dscm to mg/wscm. Determine the moisture content according to section 
6.2.2.4 of this appendix. To convert the dry basis concentration to 
wet basis, multiply it by
[GRAPHIC] [TIFF OMITTED] TP29SE16.003

).
    6.2.2 Heat Input-Based PM Emission Rates (Existing EGUs, Only). 
You must calculate hourly heat input-based PM emission rates, in 
units of lb/mmBtu, according to sections 6.2.2.1 and 6.2.2.2 of this 
appendix.
    6.2.2.1 You must select an appropriate emission rate equation 
from among Equations 19-1 through 19-9 in appendix A-7 to part 60 of 
this chapter to convert the reported hourly PM concentration value 
to units of lb/mmBtu. Note that the Method 19 equations require the 
pollutant concentration to be expressed in units of lb/scf; 
therefore, you must first multiply the PM concentration by 6.24 x 10 
-8 to convert it from mg/wscm to lb/scf.
    6.2.2.2 You must use the appropriate carbon-based or dry-basis 
F-factor listed in Table 19-2 of Method 19 in the emission rate 
equation that you have selected. However, if the appropriate F-
factor is not in Table 19-2, you may use F-factors from section 
3.3.5 or section 3.3.6 of appendix F to part 75 of this chapter.
    6.2.2.3 If the hourly average O2 concentration is 
above 14.0% O2 (19.0% for an IGCC) or the hourly average 
CO2 concentration is below 5.0% CO2 (1.0% for 
an IGCC), you may calculate the PM emission rate using the 
applicable diluent cap value (as defined in Sec.  63.10042 and 
specified in Sec.  63.10007(f)(1), provided that the diluent gas 
monitor is not out-of-control).
    6.2.2.4 If your selected Method 19 equation requires a 
correction for the stack gas moisture content, you may either use 
quality-assured hourly data from a certified part 75 moisture 
monitoring system, a fuel-specific default moisture value from Sec.  
75.11(b) of this chapter, or a site-specific default moisture value 
approved by the Administrator under Sec.  75.66 of this chapter.
    6.2.2.5 You must calculate the 30-boiler operating day rolling 
average PM emission rates according to Sec.  63.10021(b).
    6.2.3 Gross Output-Based PM Emission Rates.
    6.2.3.1 For each unit or stack operating hour, you must use the 
following equation to calculate the gross output-based PM emission 
rate, in units of lb/MWh.
[GRAPHIC] [TIFF OMITTED] TP29SE16.004

Where:

Eheo = Hourly gross output-based PM emission rate (lb/
MWh)
Ch = PM concentration (mg/wscm)
Qs = Unadjusted stack gas volumetric flow rate (scfh, wet 
basis)
MW = Gross output (megawatts)
6.24 x 10 -8 = Conversion factor
    6.2.3.2 You must calculate the 30-boiler operating day rolling 
average PM emission rates according to Sec.  63.10021(b).

7. Recordkeeping and Reporting

these data are needed to convert PM concentration data to the units 
of the emission standard. For non-operating hours, you must record 
only the items in sections 7.1.2.1 and 7.1.2.2 of this appendix. If 
you elect to or are required to comply with a gross output-based PM 
standard, for any hour in which there is gross output greater than 
zero, you must record the items in sections 7.1.2.1 through 7.1.2.3 
and (if applicable) 7.1.2.5 of this appendix; however, if there is 
heat input to the unit(s) but no gross output (e.g., at unit 
startup), you must record the items in sections 7.1.2.1, 7.1.2.2, 
and, if applicable, section 7.1.2.5 of this appendix. If you elect 
to comply with a heat input-based PM standard, you must record only

mg/wscm.
    7.1.3.3.2 If your PM CEMS measures in units of mg/acm, also 
record the hourly PM concentration in units of mg/acm, and record 
the temperature and pressure values used in Equation C-1 or C-2 of 
this appendix to convert from mg/acm to mg/wscm.
    7.1.3.3.3 If your PM CEMS measures in units of mg/dscm, also 
record the hourly PM concentration in units of mg/dscm, and record 
the moisture value used to convert from mg/dscm to mg/wscm (see

    7.1.3.6 Monitor data availability for PM concentration, as a 
percentage of unit or stack operating hours calculated according to 
Sec.  75.32 of this chapter.
    7.1.4 Stack Gas Volumetric Flow Rate Records.
    7.1.4.1 When a gross output-based PM emissions limit must be 
met, in units of lb/MWh, you must obtain hourly measurements of 
stack gas volumetric flow rate during EGU operation, in order to 
convert PM concentrations to units of the standard.
    7.1.4.2 When hourly measurements of stack gas flow rate are 
needed, you must keep hourly records of the flow rates and related 
information, as specified in Sec.  75.57(c)(2) of this chapter.
    7.1.5 Records of Diluent Gas (CO2 or O2) Concentration.
    7.1.5.1 When a heat input-based PM emission limit must be met, 
in units of lb/mmBtu, you must obtain hourly measurements of

chapter.
    7.1.6 Records of Stack Gas Moisture Content.
    7.1.6.1 When corrections for stack gas moisture content are 
needed to demonstrate compliance with the applicable PM emissions 
limit or to convert dry basis PM concentration measurements to wet 
basis:
    7.1.6.1.1 If you use a continuous moisture monitoring system, 
you must keep hourly records of the stack gas moisture content and 
related information, as specified in Sec.  75.57(c)(3) of this 
chapter.
    7.1.6.1.2 If you use a fuel-specific or approved site-specific 
default moisture value, you must represent it in the electronic 
monitoring plan required under section 7.1.1.2.1 of this appendix.
    7.1.7 PM Emission Rate Records. For applicable PM emission 
limits in units of lb/mmBtu or lb/MWh, you must record the following 
information for each affected EGU or common stack:
    7.1.7.1 The date and hour;
    7.1.7.2 The hourly PM emissions rate (lb/mmBtu or lb/MWh, as 
applicable), calculated according to section 6.2.2 or 6.2.3 of this 
appendix, rounded to three significant figures, and expressed in 
scientific notation. You must calculate the PM emission rate only 
when valid values of PM concentration and all other required 
parameters required to convert PM concentration to the units of the 
standard are obtained for the hour;
    7.1.7.3 An identification code for the formula used to derive 
the hourly PM emission rate from measurements of the PM

rate equation. For the purposes of this appendix, substitute data 
values for stack gas flow rate, CO2 concentration, 
O2 concentration, and moisture content reported under 
part 75 of this chapter are not considered to be valid data. 
However, when the gross output (as defined in Sec.  63.10042) is 
reported for an operating hour with zero output, the default value 
is treated as quality-assured data.
    7.1.8 Other Parametric Data. You must keep records of the 
parametric data (e.g., PM CEMS measurement temperature and pressure) 
used to convert the hourly PM concentrations to standard conditions.

and the calculated results for all PM CEMS correlation tests, RRAs 
and RCAs. For the correlation tests, you must indicate which model 
is used (i.e., linear, logarithmic, exponential, polynomial, or 
power) and record the correlation equation. For the RRAs and RCAs, 
the reference method readings and PM CEMS responses must be reported 
in the same units of measure as the PM CEMS correlation (i.e., 
either in mg/acm, mg/wscm, or mg/dcsm, as applicable);
    7.1.9.6 The cycle time and sample delay time for PM CEMS that 
operate in batch sampling mode; and

12. Add appendix D to subpart UUUUU to read as follows:

Appendix D to Subpart UUUUU of Part 63--PM CPMS Monitoring Provisions

1. General Provisions

    1.1 Applicability. These monitoring provisions apply to the 
continuous monitoring of the output from a particulate matter 
continuous parametric monitoring system (PM CPMS), for the purpose 
of assessing continuous compliance with an applicable emissions 
limit in Table 1 or Table 2 to this subpart.
    1.2 Summary of the Method. The output from an instrument capable 
of continuously measuring PM concentration is continuously recorded, 
either in milliamps, PM concentration, or other units of measure. An 
operating limit for the PM CPMS is established initially, based on 
data recorded by the monitoring system during a performance stack 
test. The performance test is repeated annually and the operating 
limit is reassessed. In-between successive performance tests, the 
output from the PM CPMS serves as an indicator of continuous 
compliance with the applicable emissions limit.

2. Continuous Monitoring of the PM CPMS Output

    2.1 System Design and Performance Criteria. The PM CPMS must 
meet the design and performance criteria specified in Sec. Sec.  
63.10010(h)(1)(i) through (iii) and 63.10023(b)(2)(iii) and (iv). In 
addition, an automated data acquisition and handling system (DAHS) 
is required to record the output from the PM CPMS and to generate 
the quarterly electronic data reports required under section 3.2.4 
of this appendix.
    2.2 Installation Requirements. Install the PM CPMS at an 
appropriate location in the stack or duct, in accordance with Sec.  
63.10010(a).
    2.3 Determination of Operating Limits.
    2.3.1 In accordance with Sec.  63.10007(a)(3), Sec.  
63.10011(b), Sec.  63.10023(a), and Table 6 to this subpart, you 
must determine an initial site-specific operating limit for your PM 
CPMS, using data recorded by the monitoring system during a 
performance stack test that demonstrates compliance with one of the 
following emissions limits in Table 1 or Table 2 to this subpart: 
filterable PM; total non-Hg HAP metals; total HAP metals including 
Hg (liquid oil-fired units, only); individual non-Hg HAP metals; or 
individual HAP metals including Hg (liquid oil-fired units, only).
    2.3.2 In accordance with Sec.  63.10005(d)(2)(i), you must 
perform the initial stack test no later than the applicable date in 
Sec.  63.9984(f), and according to Sec. Sec.  63.10005(d)(2)(iii) 
and 63.10006(a), the performance test must be repeated annually to 
document compliance with the emissions limit and to reassess the 
operating limit.
    2.3.3 Calculate the operating limits according to Sec.  
63.10023(b)(1) for existing units, and Sec.  63.10023(b)(2) for new 
units.
    2.4 Data Reduction and Compliance Assessment.
    2.4.1 Reduce the output from the PM CPMS to hourly averages, in 
accordance with Sec.  63.8(g)(2) and (5).
    2.4.2 To determine continuous compliance with the operating 
limit, you must calculate 30-boiler operating day rolling average 
values of the output from the PM CPMS, in accordance with Sec.  
63.10010(h)(3) through (6), Sec.  63.10021(c), and Table 7 to this 
subpart.
    2.4.3 In accordance with Sec.  63.10005(d)(2)(ii), Sec.  
63.10022(a)(2), and Table 4 to this subpart, the 30-boiler operating 
day rolling average PM CPMS output must be maintained at or below 
the operating limit. However, if exceedances of the operating limit 
should occur, you must follow the applicable procedures in Sec.  
63.10021(c)(1) and (2).

[[Page 67083]]

3. Recordkeeping and Reporting

    3.1 Recordkeeping Provisions. You must keep the applicable 
records required under Sec.  63.10032(b) and (c) for your PM CPMS. 
In addition, you must maintain a file of all measurements, data, 
reports, and other information required by this appendix in a form 
suitable for inspection, for 5 years from the date of each record, 
in accordance with Sec.  63.10033.

compliance report, the data elements in section 17 of this appendix 
(which are common to all tests) and the data elements in sections 18 
through 21 of this appendix that are associated with the reference

    15.2 For each RATA, PM CEMS correlation, RRA, or RCA, when you 
use the ECMPS Client Tool to report the test results as required 
under appendix A, B, or C to this subpart or, for SO2 
RATAs under part 75 of this chapter, you must submit along with the 
test results, the data elements in section 17 of this appendix and, 
for each test run, the data elements in sections 18 through 21 of 
this appendix that are associated with the reference method(s) used.
    15.3 For each performance stack test, RATA, PM CEMS correlation, 
RRA, and RCA, you must also provide the information described in 
section 22 of this appendix in PDF format, either along with the 
quarterly compliance report (for performance stack tests) or 
together with the test results reported under appendix A, B, or C to 
this subpart or part 75 of this chapter (for RATAs, RRAs, RCAs, or 
PM CEMS correlations).
    16.0 Applicable Reference Methods. One or more of the following 
EPA reference methods is needed for the tests described in sections 
14.1 through 14.3 of this appendix: Method 1, Method 2, Method 3A, 
Method 4, Method 5, Method 5D, Method 6C, Method 26, Method 26A, 
Method 29, and/or Method 30B.
    16.1 Application of Methods 1 and 2. If you use periodic stack 
testing to comply with an output-based emissions limit, you must 
determine the stack gas flow rate during each performance test run 
in which Reference Method 5, 5D, 26, 26A, 29, or 30B is used, in 
order to convert the measured pollutant concentration to units of 
the standard. For Methods 5, 5D, 26A and 29, which require 
isokinetic sampling, the delta-P readings made with the pitot tube 
and manometer at the Method 1 traverse points, taken together with 
measurements of stack gas temperature, pressure, diluent gas 
concentration and moisture, provide the necessary data for the 
Method 2 flow rate calculations. Note that even if you elect to 
comply with a heat input-based standard, when Method 5, 5D, 26A, or 
29 is used, you must still use Method 2 to determine the average 
stack gas velocity (vs), which is needed for the percent 
isokinetic calculation. Methods 26 and 30B do not require isokinetic 
sampling; therefore, when either of these methods is used, if the 
stack gas flow rate is needed to comply with the applicable output-
based emissions limit, you must make a separate Method 2 
determination during each test run.
    16.2 Application of Method 3A. If you elect to perform periodic 
stack testing to

[[Page 67085]]

comply with a heat input-based emissions limit, measurement of the 
diluent gas (CO2 or O2) concentration is 
required for each test run in which Method 5, 5D, 26, 26A, 29, or 
30B is used, in order to convert the measured pollutant 
concentration to units of the standard. Method 3A is the preferred 
CO2 or O2 test method, although Method 3B may 
be used instead. Diluent gas measurements are also needed for stack 
gas molecular weight determinations when using Method 2.
    16.3 Application of Method 4. For performance stack tests, 
depending on which equation is used to convert pollutant 
concentration to units of the standard, measurement of the stack gas 
moisture content, using Method 4, may also be required for each test 
run. Method 4 moisture data are also needed for Method 2 
calculations (to convert the measured flow rate from wet basis to 
dry basis) and for the RATA of an Hg CEMS that measures on a wet 
basis, when RM 30B is used. Other applications that may require 
Method 4 moisture determinations include RATAs of an SO2 
monitor (depending on the moisture basis (wet or dry) of the 
reference method and CEMS), and conversion of wet-basis pollutant 
concentrations to the units of a heat input-based emissions limit 
when certain Method 19 equations are used (e.g., Eq. 19-3, 19-4, or 
19.8). When Reference Method 5, 5D, 26A, or 29 is used for the 
performance test, the Method 4 moisture determination may be made by 
using the water collected in the impingers together with data from 
the dry gas meter; alternatively, a separate Method 4 determination 
may be made. However, when Method 26 or 30B is used, Method 4 must 
be performed separately.
    16.4 Applications of Methods 5 and 5D. Method 5 (or, if 
applicable 5D) must be used for the following applications: To 
demonstrate compliance with a filterable PM emissions limit or for 
the initial correlations, RRAs and RCAs of a PM CEMS.
    16.5 Applications of Method 6C. If you elect to monitor 
SO2 emissions from your coal-fired EGU as a surrogate for 
HCl, the SO2 CEMS must be installed, certified, operated, 
and maintained according to 40 CFR part 75. Part 75 allows the use 
of Reference Methods 6, 6A, 6B, and 6C for the required RATAs of the 
SO2 monitor. However, in practice, only the instrumental 
method (6C) is used.
    16.6 Applications of Methods 26 and 26A. Method 26A may be used 
for quarterly HCl or HF stack testing, or for the RATA of an HCl or 
HF CEMS. Method 26 may be used for quarterly HCl or HF stack 
testing; however, for the RATAs of an HCl monitor that is following 
Performance Specification 18 and Procedure 6 in appendices B and F 
to part 60 of this chapter, Method 26 may only be used if approved 
upon request.
    16.7 Applications of Method 29. Method 29 may be used for 
periodic performance stack tests to determine compliance with 
individual or total HAP metals emissions limits. For coal-fired 
EGUs, the total HAP emissions limits exclude Hg.
    16.8 Applications of Method 30B. Method 30B is used for 30-
boiler operating day Hg LEE tests and RATAs of Hg CEMS and sorbent 
trap monitoring systems, and may be used for quarterly Hg stack 
testing (oil-fired EGUs, only).
