ACTION: Proposed rule. AGENCY: The Environmental Protection Agency (EPA) is proposing to amend the electronic reporting requirements for the National Emission Standards for Hazardous Air Pollutants: Coal- and OilFired 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.

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 § 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 § 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 NAICS code 1 Category Industry ..................................................... Federal government .................................. State/local/Tribal government ................... VerDate Sep<11>2014 19:22 Sep 28, 2016 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 twophased 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 § 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 Jkt 238001 221112 2 221122 2 221122 PO 00000 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. II.

Alexander Drive, Research Triangle Park, North Carolina 27711, and Attention Docket ID 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 § 63.10031(f) from April 16, 2017, to December 31, 2017. In addition, this proposed rule would amend the reporting requirements in § 63.10031 of VerDate Sep<11>2014 19:22 Sep 28, 2016 Jkt 238001 the MATS regulation, and, for consistency with those changes, would amend related texts in §§ 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. 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. 1 The EPA has recently published a technologyneutral 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. PO 00000 Frm 00004 Fmt 4701 Sfmt 4702 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 § 63.10031 The reporting section of MATS, i.e., § 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 § 63.10031(f) would end on E:\FR\FM\29SEP2.SGM 29SEP2 mstockstill on DSK3G9T082PROD with PROPOSALS2 Federal Register / Vol. 81, No. 189 / Thursday, September 29, 2016 / Proposed Rules 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 § 63.10031(e)(1)). (c) Although the interim PDF reporting process described in § 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 § 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 30boiler 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 § 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 § 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 VerDate Sep<11>2014 19:22 Sep 28, 2016 Jkt 238001 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 § 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 § 63.10031(g)). The quarterly compliance reports plus attachments would consolidate other PO 00000 Frm 00005 Fmt 4701 Sfmt 4702 67065 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; E:\FR\FM\29SEP2.SGM 29SEP2 mstockstill on DSK3G9T082PROD with PROPOSALS2 67066 Federal Register / Vol. 81, No. 189 / Thursday, September 29, 2016 / Proposed Rules (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 § 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 § 63.10031(d) would require reporting of the range of dates and the cause (if known) of each excess emission, as defined in § 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 § 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 § 63.10042, the information in § 63.10020(e), which is referenced in § 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 VerDate Sep<11>2014 19:22 Sep 28, 2016 Jkt 238001 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 § 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 § 63.10(e)(3)(v) and (vi), if the EGU owner or operator PO 00000 Frm 00006 Fmt 4701 Sfmt 4702 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 § 63.10042, the parametric data and other information in § 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 § 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 E:\FR\FM\29SEP2.SGM 29SEP2 Federal Register / Vol. 81, No. 189 / Thursday, September 29, 2016 / Proposed Rules mstockstill on DSK3G9T082PROD with PROPOSALS2 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 30day 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 § 63.10031 The proposed revisions to § 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 § 63.10011(e) would require Notifications of Compliance Status for the initial and subsequent compliance demonstrations to be submitted in accordance with VerDate Sep<11>2014 19:22 Sep 28, 2016 Jkt 238001 § 63.10030(e) and § 63.10031(f)(4) and proposed § 63.10031(h). This change is necessary to include all initial and subsequent compliance demonstration submissions. Both the interim reporting process described in § 63.10031(f)(4) and the proposed on-going reporting requirement in § 63.10031(h) require these Notifications to be submitted in PDF format, through ECMPS. (b) Section 63.10011(g)(3), § 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 § 63.10031(i). For EGU owners or operators relying on paragraph (2) of the definition of startup in § 63.10042, § 63.10031(i) would retain the requirement for the parametric data and other information referenced in § 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 § 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 § 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 § 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 § 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 PO 00000 Frm 00007 Fmt 4701 Sfmt 4702 67067 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 20percent relative accuracy (RA) specification must be used and when the alternate specification applies. In Table A–2, it appears that the 20percent RA specification only applies when the average CMS value (Cavg) is ≥2.5 micrograms per standard cubic meter (mg/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 mg/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 ongoing 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 E:\FR\FM\29SEP2.SGM 29SEP2 mstockstill on DSK3G9T082PROD with PROPOSALS2 67068 Federal Register / Vol. 81, No. 189 / Thursday, September 29, 2016 / Proposed Rules 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 § 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 VerDate Sep<11>2014 19:22 Sep 28, 2016 Jkt 238001 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 ongoing 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 § 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. PO 00000 Frm 00008 Fmt 4701 Sfmt 4702 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 E:\FR\FM\29SEP2.SGM 29SEP2 mstockstill on DSK3G9T082PROD with PROPOSALS2 Federal Register / Vol. 81, No. 189 / Thursday, September 29, 2016 / Proposed Rules 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 § 75.32. Proposed sections 3.2.2 and 3.2.3, respectively, require notifications (to be provided in accordance with § 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 § 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. VerDate Sep<11>2014 19:22 Sep 28, 2016 Jkt 238001 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 § 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 PO 00000 Frm 00009 Fmt 4701 Sfmt 4702 67069 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 https://www2.epa.gov/lawsregulations/laws-and-executive-orders. A. Executive Order 12866: Regulatory Planning and Review and Executive Order 13563: Improving Regulation and Regulatory Review This action is not a significant regulatory action and was, therefore, not submitted to 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 30boiler operating day rolling averages for E:\FR\FM\29SEP2.SGM 29SEP2 mstockstill on DSK3G9T082PROD with PROPOSALS2 67070 Federal Register / Vol. 81, No. 189 / Thursday, September 29, 2016 / Proposed Rules 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 VerDate Sep<11>2014 19:22 Sep 28, 2016 Jkt 238001 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 ORIA_submissions@ omb.eop.gov, 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 PO 00000 Frm 00010 Fmt 4701 Sfmt 4702 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.

Add appendix C to subpart UUUUU to read as follows: ■ mstockstill on DSK3G9T082PROD with PROPOSALS2 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. VerDate Sep<11>2014 19:22 Sep 28, 2016 Jkt 238001 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 § 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, § 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 § 63.10010 and section 2.4 of PS 11. PO 00000 Frm 00018 Fmt 4701 Sfmt 4702 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.

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 PO 00000 Frm 00022 Fmt 4701 Sfmt 4702 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.

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 inputbased 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 E:\FR\FM\29SEP2.SGM 29SEP2 mstockstill on DSK3G9T082PROD with PROPOSALS2 Federal Register / Vol. 81, No. 189 / Thursday, September 29, 2016 / Proposed Rules 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).

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.

one complete version of the comments that includes information claimed
as CBI, you must submit a copy of the comments that does not contain
the information claimed as CBI for inclusion in the public docket. If
you submit a CD-ROM or disk that does not contain CBI, mark the outside
of the disk or CD-ROM clearly that it does not contain CBI. Information
not marked as CBI will be included in the public docket and the EPA's
electronic public docket without prior notice. Information marked as
CBI will not be disclosed except in accordance with procedures set
forth in 40 CFR part 2. Send or deliver information identified as CBI
only to the following address: OAQPS Document Control Officer (C404-

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.

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 ORIA_submissions@omb.eop.gov, 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]]

paragraphs (f)(6)(i) through (xii) of this section must be entered into
ECMPS with each startup and shutdown report.
(j) If you elect to use a certified PM CEMS to monitor PM emissions
continuously to demonstrate compliance with this subpart and have begun
recording valid data from the PM CEMS prior to January 1, 2018, you
must use the ECMPS Client Tool to submit a detailed report of your PS
11 correlation test in PDF format no later than December 31, 2017. The
applicable data elements in paragraphs (f)(6)(i) through (xii) of this
section must be entered into ECMPS with the PDF report.
(k) If you elect to demonstrate compliance using a PM CPMS, you

Provisions

* * * * *

2. Monitoring of HCl and/or HF Emissions

* * * * *
2.3 Monitoring System Equipment, Supplies, Definitions, and
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

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.

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
each test run, the reference method used, the HCl concentrations
measured by the reference method and CEMS for each test run, 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.
10.1.8.1.11 For each quarterly cylinder gas audit (CGA) of an
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

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.
5.3.1 General Requirements.
5.3.1.1 Preventive Maintenance. You must keep a written record
of the procedures needed to maintain the PM CEMS and other equipment

Rate, and Moisture Monitoring Systems. The QA/QC program
requirements for the stack gas flow rate, diluent gas, and moisture
monitoring systems described in section 3.2.3 of this appendix are
specified in section 1 of appendix B to part 75 of this chapter.
5.3.4 Requirements for Other Monitoring Equipment. If any other
equipment is required to convert readings from the PM CEMS to
standard conditions (e.g., devices to measure temperature and
pressure), you must keep a written record of the calibrations and/or
other procedures used to ensure that the devices provide accurate
data.
5.3.5 You may store your QA/QC plan electronically, provided
that you can make the information available expeditiously in hard
copy to auditors or inspectors.

6. Data Reduction and Calculations

6.1 Data Reduction and Validation.
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

7.1 Recordkeeping Provisions. For the PM CEMS and the other
necessary continuous monitoring systems and parameter measurement
devices installed at each affected unit or common stack, you must
maintain a file of all measurements, data, reports, and other

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

assured PM concentration is obtained for the hour; and
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

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).

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).
