Testing Regulations for Air Emission Sources, 56713-56734 [2018-24747]

Download as PDF Federal Register / Vol. 83, No. 220 / Wednesday, November 14, 2018 / Rules and Regulations southeast (from west to east). The area is defined as that airspace upward from 700 feet above the surface within the area bounded by a line beginning at lat. 58°27′33″ N, long. 134°37′40″ W, to lat. 58°13′13″ N, long. 134°11′51″ W, to lat. 58°05′59″ N, long. 134°21′04″ W, to lat. 58°10′51″ N, long. 134°59′18″ W, to lat. 58°23′41″ N, long. 135°31′13″ W, to lat. 58°32′22″ N, long. 135°18′32″ W, to lat. 58°27′17″ N, long. 135°01′27″ W, thence to the point of beginning. This modification reduces the airspace area to only that area necessary to contain IFR operations as they transition between the airport and en route environments. Also, Class E airspace extending upward from 1,200 feet above the surface designated for Juneau International Airport is removed since this airspace is wholly contained within the Southeast Alaska Class E en route airspace, and duplication is not necessary. This action also makes an editorial change to the Class D airspace legal description replacing Airport/Facility Directory with Chart Supplement. Regulatory Notices and Analyses The FAA has determined that this regulation only involves an established body of technical regulations for which frequent and routine amendments are necessary to keep them operationally current, is non-controversial and unlikely to result in adverse or negative comments. It, therefore: (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866; (2) is not a ‘‘significant rule’’ under DOT Regulatory Policies and Procedures (44 FR 11034; February 26, 1979); and (3) does not warrant preparation of a Regulatory Evaluation as the anticipated impact is so minimal. Since this is a routine matter that only affects air traffic procedures and air navigation, it is certified that this rule, when promulgated, will not have a significant economic impact on a substantial number of small entities under the criteria of the Regulatory Flexibility Act. PART 71 —DESIGNATION OF CLASS A, B, C, D, AND E AIRSPACE AREAS; AIR TRAFFIC SERVICE ROUTES; AND REPORTING POINTS airport 3-mile radius to 5 miles southeast of the airport, excluding that airspace below 2,000 feet MSL within the area bounded by a line beginning at lat. 58°19′35″ N, long. 134°24′31″ W, to lat. 58°19′02″ N, long. 134°25′33″ W, to lat. 58°20′16″ N, long. 134°27′28″ W, to lat. 58°20′34″ N, long. 134°26′22″ W, thence to the point of beginning. This Class E airspace area is effective during the specific dates and times established in advance by a Notice to Airmen. The effective date and time will thereafter be continuously published in the Chart Supplement. 1.

General Information A. Does this action apply to me? The revisions promulgated in this final rule apply to industries that are subject to the current provisions of 40 Code of Federal Regulations (CFR) parts 51, 60, and 63. We did not list all of the specific affected industries or their North American Industry Classification System (NAICS) codes herein since there are many affected sources in numerous NAICS categories. If you have any questions regarding the applicability of this action to a particular entity, consult either the air permitting authority for the entity or your EPA Regional representative as listed in 40 CFR 63.13. B. What action is the agency taking? We are promulgating corrections and updates to regulations for source testing of emissions. More specifically, we are correcting typographical and technical errors, updating obsolete testing procedures, adding approved testing alternatives, and clarifying testing requirements. C. Judicial Review Under section 307(b)(1) of the Clean Air Act (CAA), judicial review of this final rule is available by filing a petition for review in the United States Court of Appeals for the District of Columbia Circuit by January 14, 2019. Under section 307(d)(7)(B) of the CAA, only an objection to this final rule that was raised with reasonable specificity during the period for public comment can be raised during judicial review. Moreover, under section 307(b)(2) of the CAA, the requirements that are the subject of this final rule may not be challenged later in civil or criminal proceedings brought by the EPA to enforce these requirements. II. Background The revisions to testing regulations for air emission sources were proposed in the Federal Register on January 26, 2018 (83 FR 3636). The public comment period ended March 27, 2018, and 83 comment letters were received from the public; 23 of the comment letters were relevant, and the other 60 comment letters were considered beyond the scope of the proposed rule. This final rule was developed based on public comments that the agency received on the proposed rule. III. Summary of Amendments A. Method 201A of Appendix M of Part 51 In Method 201A, in section 12.5, the denominator of equation 24 is corrected E:\FR\FM\14NOR1.SGM 14NOR1 Federal Register / Vol. 83, No. 220 / Wednesday, November 14, 2018 / Rules and Regulations as proposed; the proposed c′p in the denominator is changed to Cp′ to be consistent with the nomenclature in section 12.1. The cp in the numerator is changed to Cp also to be consistent with the nomenclature in section 12.1. B. Method 204 of Appendix M of Part 51 In Method 204, in section 8.2, the statement regarding equation 204–2 is corrected to ‘‘The NEAR must be ≤0.05,’’ as proposed. C. Method 205 of Appendix M of Part 51 In Method 205, section 2.1.1 is revised to allow the use of National Institute of Standards and Technology (NIST)-traceable transfer standards to calibrate the gas dilution system as proposed. The agency continues to believe that these standards are widely available and provide the accuracy necessary to perform the calibration. Section 2.1.1 is also revised as proposed to require testers to report the results of the calibration of the dilution system to enable the regulatory authority to review this information. D. General Provisions (Subpart A) of Part 60 In the General Provisions of part 60, § 60.17(h) is revised as proposed to add ASTM D6216–12 to the list of incorporations by reference and to renumber the remaining consensus standards that are incorporated by reference in alpha-numeric order. E. Fossil-Fuel-Fired Steam Generators (Subpart D) Part 60 In a change from proposal, the allowed filter temperature in § 60.46(b)(2)(i) is not revised. Based on comments we received on the proposed revisions, we are deferring finalizing the proposed revisions of the temperature tolerances of probe and filter holder heating systems as part of this rulemaking. We will continue to review supporting information and data we received on the proposed rule and may propose either revisions or similar requirements as part of future rulemakings. F. Electric Utility Steam Generating Units (Subpart Da) Part 60 In a change from proposal, the allowed filter temperature in § 60.50Da (b)(1)(ii)(A) is not revised. Based on comments we received on the proposed revisions, we are deferring finalizing the proposed revisions of the temperature tolerances of probe and filter holder heating systems as part of this rulemaking. We will continue to review VerDate Sep<11>2014 18:08 Nov 13, 2018 Jkt 247001 supporting information and data we received on the proposed rule and may propose either revisions or similar requirements as part of future rulemakings. G. Industrial-Commercial-Institutional Steam Generating Units (Subpart Db) Part 60 In a change from proposal, the allowed filter temperature in § 60.46b(d)(4) is not revised. Based on comments we received on the proposed revisions, we are deferring finalizing the proposed revisions of the temperature tolerances of probe and filter holder heating systems as part of this rulemaking. We will continue to review supporting information and data we received on the proposed rule and may propose either revisions or similar requirements as part of future rulemakings. H. Small Industrial-CommercialInstitutional Steam Generating Units (Subpart Dc) Part 60 In a change from proposal, the allowed filter temperature in § 60.45c(a)(5) is not revised. Based on comments we received on the proposed revisions, we are deferring finalizing the proposed revisions of the temperature tolerances of probe and filter holder heating systems as part of this rulemaking. We will continue to review supporting information and data we received on the proposed rule and may propose either revisions or similar requirements as part of future rulemakings. I. Municipal Waste Combustors for Which Construction is Commenced After December 20, 1989 and on or Before September 20, 1994 (Subpart Ea) Part 60 In a change from proposal, the allowed filter temperature in § 60.58a(b)(3) is not revised. Based on comments we received on the proposed revisions, we are deferring finalizing the proposed revisions of the temperature tolerances of probe and filter holder heating systems as part of this rulemaking. We will continue to review supporting information and data we received on the proposed rule and may propose either revisions or similar requirements as part of future rulemakings. J. Glass Manufacturing Plants (Subpart CC) Part 60 In a change from proposal, the allowed filter temperatures in §§ 60.293(f) and 60.296(d)(2) are not revised. Based on comments we received on the proposed revisions, we PO 00000 Frm 00017 Fmt 4700 Sfmt 4700 56715 are deferring finalizing the proposed revisions of the temperature tolerances of probe and filter holder heating systems as part of this rulemaking. We will continue to review supporting information and data we received on the proposed rule and may propose either revisions or similar requirements as part of future rulemakings. K. New Residential Wood Heaters, New Residential Hydronic Heaters and Forced-Air Furnaces (Subpart QQQQ) Part 60 In subpart QQQQ, in Method 28WHH, in section 13.5.1, equation 8 is corrected as proposed. L. Method 2B of Appendix A–1 of Part 60 In Method 2B, in section 12.1, the definition of ambient carbon dioxide concentration is revised as proposed. The agency continues to believe that the global monthly mean (CO2)a concentration varies over time. Also, a website link is added to the definition as specified at proposal. M. Method 5 of Appendix A–3 of Part 60 In a change from proposal, allowed filter temperatures in Method 5, sections 2.0, 6.1.1.2, 6.1.1.6, 6.1.1.7, and 8.5 are not revised. Based on comments we received on the proposed revisions, we are deferring finalizing the proposed revisions of the temperature tolerances of probe and filter holder heating systems as part of this rulemaking. We will continue to review supporting information and data we received on the proposed rule and may propose either revisions or similar requirements as part of future rulemakings. Section 6.1.1.9 is revised as proposed to allow the use of a single temperature sensor in lieu of two temperature sensors on the dry gas meter as allowed by Technical Information Document 19 (TID–19) and the approved broadly applicable alternative, ALT–117 (see https://www.epa.gov/emc). Consistent with our response to the comment regarding allowing flexibility for the weighing container in section 11.2.1, Method 5B, the first sentence in section 11.2.1, Method 5 is revised similarly. N. Method 5B of Appendix A–3 of Part 60 In a change from proposal, the allowed filter temperatures in Method 5B, sections 2.0, 6.1, and 8.2 are not revised. Based on comments we received on the proposed revisions, we are deferring finalizing the proposed revisions of the temperature tolerances of probe and filter holder heating E:\FR\FM\14NOR1.SGM 14NOR1 56716 Federal Register / Vol. 83, No. 220 / Wednesday, November 14, 2018 / Rules and Regulations systems as part of this rulemaking. We will continue to review supporting information and data we received on the proposed rule and may propose either revisions or similar requirements as part of future rulemakings. Section 11.0 is revised as proposed to replace the reference to Method 5, section 11.0 with specific analytical procedures and to report the results using Figure 5B–1 for complete data review. Section 17.0 is revised as proposed to delete the word ‘‘Reserved’’ from the title, and Figure 5B–1 (Analytical Data Sheet) is added. O. Method 5I of Appendix A–3 of Part 60 In a change from proposal, Method 5I, sections 2.1 and 8.5.2.2 are not revised to tighten the allowed filter temperatures. Based on comments we received on the proposed revisions, we are deferring finalizing the proposed revisions of the temperature tolerances of probe and filter holder heating systems as part of this rulemaking. We will continue to review supporting information and data we received on the proposed rule and may propose either revisions or similar requirements as part of future rulemakings. P. Method 7 of Appendix A–4 of Part 60 In Method 7, sections 10.1.2 and 11.3 reference erroneous sections; the correct section is inserted, as proposed. The proposed referenced section 10.1.1.2 is changed to 10.1.1 to include procedures in both sections 10.1.1.1 and 10.1.1.2. Q. Method 8 of Appendix A–4 of Part 60 As proposed, Method 8, sections 6.1.1.1 through 6.1.1.4 are renumbered to 6.1.1.2 through 6.1.1.5; a new section 6.1.1.1 is added to clarify the requirements that apply to the probe nozzle; and, in response to comments, Figure 8–1 (Sulfuric Acid Sampling Train) is corrected by: (1) Modifying the impinger graphics to make it consistent with the text in section 6.1.1.4 and (2) revising the proposed label S-Type Pitot Tube to Type S Pitot Tube for consistency. The proposed first sentence in section 6.1.1.1 is revised to ‘‘Borosilicate or quartz glass with a sharp, tapered leading edge and coupled to the probe liner using a polytetrafluoroethylene (PTFE) or glasslined union (e.g., fused silica, Silico, or equivalent).’’ Based on a public comment that recommended adding Silco coated stainless steel unions as an option for Teflon unions, and for consistency with other test methods, we have replaced Teflon with the generic option polytetrafluoroethylene (PTFE). VerDate Sep<11>2014 18:08 Nov 13, 2018 Jkt 247001 R. Method 18 of Appendix A–6 of Part 60 In Method 18, in section 13.1, the erroneous paragraph (c) designation is re-designated as (b), as proposed. S. Method 22 of Appendix A–7 of Part 60 In Method 22, sections 11.2.1 and 11.2.2 are revised as proposed to allow digital photography to be used for a subset of the recordkeeping requirements. As proposed, section 11.2.3 is added to specify the requirements for digital photographic records. In response to comments on the proposal, the next to the last sentence in section 11.2.3 regarding photographs that must be taken within 15 minutes of the observation period is revised from the proposal, and another sentence is added to provide clarity. The revised and new sentences read: ‘‘The photograph(s) representing the environmental conditions including the sky conditions and the position of the sun relative to the observer and the emission point must be taken within a reasonable time of the observation (i.e., 15 minutes). When observations are taken from exactly the same observation point on a routine basis (e.g., daily) and as long as there are no modifications to the units depicted, only a single photograph each day is necessary to document the observer’s location relative to the emissions source, the process unit being observed, and the location of potential and actual emission points.’’ The agency notes that ALT–109 (see https://www.epa.gov/ emc) is the associated broadly applicable alternative that allows the use of digital photographs for specific recordkeeping requirements. T. Method 26 of Appendix A–8 of Part 60 As proposed, Method 26, section 6.2.2 is revised to allow the use of glass sample storage containers as an option to allow flexibility and to be consistent with Method 26A. The proposed title of section 6.2.2, ‘‘Storage Bottles,’’ is changed to ‘‘Storage Containers’’ to be consistent with the language in section 6.2.2. U. Method 26A of Appendix A–8 of Part 60 As proposed, in Method 26A, section 6.2.1 is revised to remove the language regarding sample storage containers. In response to comments on our proposal, we have determined that high-density polyethylene is an acceptable material for sample storage containers in addition to the currently allowed glass. Therefore, in a new section 6.2.4., we PO 00000 Frm 00018 Fmt 4700 Sfmt 4700 have specified that both high-density polyethylene and glass are acceptable sample storage containers. V. Test Method 28WHH of Appendix A– 8 of Part 60 In Test Method 28WHH, equation 8 in section 13.5.1 is corrected, as proposed. W. Performance Specification 1 of Appendix B of Part 60 As proposed, in Performance Specification 1, references to ASTM D6216–98 (in sections 2.1, 3.1, 6.1, 8.1(1), 8.1(3)(ii), 8.2(1), 8.2(2), 8.2(3), 9.0, 12.1, 13.0, 13.1, 13.2, and 16.0 paragraph 8) are replaced with ASTM D6216–12. As noted at proposal, if the initial certification of the continuous opacity monitoring system (COMS) has already occurred using D6216–98, D6216–03, or D6216–07, it will not be necessary to recertify using D6216–12. In response to comments on our decision to add ASTM D6216 to the list of consensus standards, the April 1998 publication date for ASTM D6216 in paragraph 8 in section 16.0 is replaced with October 2012, the ASTM D6216–12 publication date. In response to comments, for consistency with section 2.1, and for purposes of clarification, the note at the end of section 2.1 is added to section 13.0. X. Performance Specification 2 of Appendix B of Part 60 In Performance Specification 2, section 13.2 is replaced with a table that indicates the relative accuracy performance specifications, as proposed. Given that the equals to (=) signs were erroneously omitted from several of the < and > values during publication of the table in the proposed rule, these values have been corrected. Y. Performance Specification 3 of Appendix B of Part 60 In Performance Specification 3, the two sentences in section 12.0 that read, ‘‘Calculate the arithmetic difference between the RM and the CEMS output for each run. The average difference of the nine (or more) data sets constitute the RA.’’ are deleted, as proposed; these two sentences are no longer necessary since equations 3–1 and 3–2 would be moved from section 13.2 to section 12.0. The sentence, ‘‘Calculate the RA using equations 3–1 and 3–2.’’ is added to the beginning of section 12.0. Z. Performance Specification 11 of Appendix B of Part 60 In Performance Specification 11, section 13.1, the word ‘‘average’’ erroneously exists in the second sentence and is deleted, as proposed. E:\FR\FM\14NOR1.SGM 14NOR1 Federal Register / Vol. 83, No. 220 / Wednesday, November 14, 2018 / Rules and Regulations AA. Performance Specification 15 of Appendix B of Part 60 As proposed, in Performance Specification 15, section 13.0 is added as ‘‘Method Performance [Reserved].’’ BB. Performance Specification 18 of Appendix B of Part 60 As proposed, in Performance Specification 18, in section 11.8.7, the last sentence is revised to clarify the duration of the drift check. In Table 1, the erroneous acronym ‘‘NO2’’ is replaced with ‘‘NO,’’ as proposed. In the appendix of Performance Specification 18, the inadvertently omitted reserved section 12.0 is added, as proposed. CC. Procedure 1 of Appendix F of Part 60 As proposed, in Procedure 1, in section 5.1.2 (1), the sentence immediately following the table that reads, ‘‘Challenge the CEMS three times at each audit point, and use the average of the three responses in determining accuracy.’’ is replaced with, ‘‘Introduce each of the audit gases, three times each for a total of six challenges. Introduce the gases in such a manner that the entire CEMS is challenged. Do not introduce the same gas concentration twice in succession.’’ In order to obtain six distinct readings during the cylinder gas audit (CGA), the same gas must not be introduced twice in succession, and this revised language accurately reflects this standard scientific practice. As also proposed, in section 5.1.2 (3), the reference to EPA’s traceability protocol for gaseous calibration standards is updated, and the language regarding the use of EPA Method 205 for dilution of audit gases is clarified. DD. General Provisions (Subpart A) of Part 63 Sections 63.7(g)(2), 63.7(g)(2)(v), and 63.8(e)(5)(i) of the General Provisions (subpart A) of part 63 are revised, as proposed, to require the reporting of specific test data for continuous monitoring system performance evaluation tests and ongoing quality assurance (QA) tests. These data elements are required regardless of the format of the report, i.e., electronic or paper. These modifications will ensure that performance evaluation and QA test reporting include all data necessary for the compliance authority to assess and assure the quality of the reported data and that the reported information describes and identifies the specific unit covered by the evaluation test report. In response to comment, we specified the level of reporting needed for continuous parameter monitoring systems (CPMS) versus other continuous monitoring VerDate Sep<11>2014 18:08 Nov 13, 2018 Jkt 247001 systems including continuous emission monitoring systems (CEMS), COMS, and predictive emissions monitoring systems (PEMS). EE. Wool Fiberglass Manufacturing (Subpart NNN) Part 63 In a change from proposal, the allowed filter temperature in § 63.1385(a)(5) is not revised. Based on comments we received on the proposed revisions, we are deferring finalizing proposed revisions of the temperature tolerances of probe and filter holder heating systems as part of this rulemaking. We will continue to review supporting information and data we received on the proposed rule and may propose either revisions or similar requirements as part of future rulemakings. FF. Major Sources: Industrial, Commercial, and Institutional Boilers and Process Heaters (Subpart DDDDD) Part 63 As proposed, in Table 6 of subpart DDDDD, row 1.f. is revised to allow the use of EPA SW–846–7471B (for liquid samples) in addition to EPA SW–846– 7470A for measuring mercury to allow for compliance flexibility. GG. Coal- and Oil-Fired Electric Utility Steam Generating Units (Subpart UUUUU) Part 63 In a change from proposal, the allowed filter temperature in § 63.10010(h)(7)(i)(1) is not revised. Based on comments we received on the proposed revisions, we are deferring finalizing proposed revisions of the temperature tolerances of probe and filter holder heating systems as part of this rulemaking. We will continue to review supporting information and data we received on the proposed rule and may propose either revisions or similar requirements as part of future rulemakings. As proposed, in Table 5, Method 5I is specified as a test method option because, as explained at proposal, Method 5I is designed for low particulate matter (PM) application. HH. Method 303 of Appendix A of Part 63 In Method 303, section 12.4, equation 303–3 is corrected, as proposed, by inserting ‘‘where y = ’’ in front of the equation. II. Method 308 of Appendix A of Part 63 As proposed, in Method 308, deionized distilled water replaces the aqueous n-proponal solution; the affected sections are 2.0, 7.2.2, 7.2.3.3, and 11.3.2. Section 7.2.2, which defines PO 00000 Frm 00019 Fmt 4700 Sfmt 4700 56717 the aqueous n-proponal solution, is removed, as proposed. In section 7.2.3.3, the erroneous ‘‘four’’ is replaced as proposed, with ‘‘three’’ in the sentence that reads ‘‘Pipette 5, 15, and 25 ml of this standard, respectively into four 50-ml volumetric flasks.’’ Section 8.1.2 is revised, as proposed, to require a leak check prior to the sampling run (in addition to after the sampling run) for QA purposes; as explained at proposal, requiring a leak check prior to the sampling run would potentially save time and money. In section 9.1, methanol spike recovery check is added as a quality control (QC) measure in Table 9.1, as proposed. In section 12.1, variables used in equations 308–4 and 308–5 are added and section 12.5, which includes equations 308–4 and 308–5, is added, as proposed. In section 13.0, the title ‘‘Reserved’’ is replaced with ‘‘Method Performance’’ and QA requirements would be added to be consistent with other methods, as proposed. The erroneous proposed paragraph (a) of section 13.0 is replaced, as proposed, with ‘‘Calibration standards must meet the requirements in section 10.2.1 or 10.2.2 as applicable.’’ JJ. Method 320 of Appendix A of Part 63 In section 8.2.2.4, the denominator in equation 2 is corrected from PSS to PS, as proposed. In section 9.2.3, the word ‘‘where’’ in the statement, ‘‘Calculate the dilution ratio using the tracer gas as follows: where:’’ is deleted, as proposed. Also in section 9.2.3, the inadvertently superscripted ‘‘dir’’ on the definition of spike is subscripted, as proposed. KK. Method 323 of Appendix A of Part 63 In Method 323, section 12.9, the denominator in equation 323–8 is corrected, as proposed. LL. Method 325A of Appendix A of Part 63 In Method 325A, section 8.2.1.3 is revised, as proposed, to clarify that only one extra sampling site is required near known sources of volatile organic compounds (VOCs) when the source is located both within 50 meters of the boundary and between two monitors. Based on a public comment we received on the proposed regulatory text, wording changes have been made to the language in section 8.2.1.3. As proposed, the label under Figure 8.1 is corrected from ‘‘Refinery (20% angle)’’ to ‘‘Refinery (20° angle).’’ Section 8.2.3.2 is revised, as proposed, to include facilities with a monitoring perimeter length equal to 7,315 meters (24,000 feet). Section 8.2.3.3 is added, as E:\FR\FM\14NOR1.SGM 14NOR1 56718 Federal Register / Vol. 83, No. 220 / Wednesday, November 14, 2018 / Rules and Regulations proposed, to provide clarification and an equivalent procedure in Option 2 (linear distance between sites) for site locations that parallel section 8.2.2.2.4 in Option 1 (radial distance between sites). In response to comments, section 8.4.3 is added to address worker safety during extenuating circumstances. MM. Method 325B of Appendix A of Part 63 In Method 325B, section 9.3.2 is revised, as proposed, to correct an error in the number of field blank samples required for a sampling period and to provide consistency with the sample analysis required in Method 325B. In sections 9.13 and 11.3.2.5, the erroneous reference to section 10.6.3 is corrected to 10.0, as proposed. Also in section 11.3.2.5, the erroneous reference to section 10.9.5 is corrected to 9.13, as proposed. Section 12.2.2 is revised, as proposed, to correct the calculation of target compound concentrations at standard conditions, and the erroneous reference to Ustd in the note in section 12.2.2 is revised to UNTP. Sections 12.2.3 and 12.2.4 are deleted, as proposed, because the equations for target concentrations are incorrect. Table 17– 1 is revised, as proposed, to add inadvertently omitted QC criteria from section 9.3.3. IV. Public Comments on the Proposed Rule Eighty-three (83) comment letters were received from the public; 23 of the comment letters were relevant, and the other 60 comment letters were considered as beyond the scope of the proposed rule. The public comments and the agency’s responses are summarized in the Response to Comments document located in the docket for this rule. See the ADDRESSES section of this preamble. A summary of the relevant portions of significant comments that we received on the proposal and agency responses are presented below. Comment: Three commenters provided comments on our proposed revisions to the General Provisions (Subpart A) of Part 63. One commenter stated that the proposed revisions impose new requirements on CMS performance evaluations and QA testing for types of monitors not previously subject to such requirements. Another commenter remarked that the proposed revisions to various requirements in Part 63 revisions were vague. Yet another commenter remarked that the proposed revisions to § 63.8(e)(5) would shorten the CMS performance evaluation reporting period for CMS associated with performance tests. VerDate Sep<11>2014 18:08 Nov 13, 2018 Jkt 247001 Response: We disagree with the comment that the proposed changes to § 63.8(e)(5)(i) would impose new requirements given that at proposal, the agency had explained that they were intended to clarify and codify data elements and reporting requirements that are already routinely requested by the Administrator’s delegated authorities. With regard to § 63.8(e)(5), in a change from proposal, we have retained the existing requirement that allows for the simultaneous submission of the report of a CMS performance evaluation with results of performance testing required under 40 CFR 63.7. We also edited the final rule language for 40 CFR 63.7(g)(2)(v) to improve clarity and to eliminate confusion. Comment: Fifteen commenters provided comments arguing against the proposal to tighten the filter temperature tolerance in 40 CFR 60.46(b)(2)(i); 60.50Da(b)(1)(ii)(A); 60.45c(a)(5); 60.58a(b)(3); 60.293(f); 60.296(d)(2); 63.1385(a)(5); and sections 2.0, 6.1.1.2, 6.1.1.6, 6.1.1.7 and 8.5 of Method 5, Appendix A–3 of Part 60. They cited issues that included: weather (e.g., ambient temperature fluctuations and windy conditions); costs; lack of justification and data for the revision; inconsistent language (e.g., the use of ‘‘shall’’ vs. ‘‘may’’ and proposed revisions to temperature tolerance in Methods 5, 5B, and 5I but not in Methods 5D, 5E, and 5F); and safety risks. Nine commenters remarked that ambient conditions (cold climates, wind gusts, etc.) can cause temperature fluctuations that are difficult to manage. More specifically, one commenter stated that the reduced allowable temperature range would be problematic during testing in cold, windy ambient conditions that are persistent in the winter months in northern climates because the time required for temperature recovery after a component change in these conditions could add hours and possibly days to testing programs. One commenter remarked that the proposed ±5 °C is unattainable for sources in cold or windy climates. Eight commenters stated that alteration or replacement of equipment components would likely be necessary to achieve the proposed temperature tolerances resulting in additional costs. One commenter noted potential equipment improvements, such as increased probe sheath tubing diameter to make room for added insulation around every probe heater; re-design of filter heating ovens; improved sealing and insulation of the openings at the inlet and outlet of filter heating ovens; and/or for sources with high stack temperatures, more frequent use of air- PO 00000 Frm 00020 Fmt 4700 Sfmt 4700 cooled or water-cooled probes. One commenter remarked that this revision would force cold weather stack testers to replace or retrofit equipment with higher power heating devices and possibly more refined control devices which would be costly. One commenter remarked that this revision will most likely require air sampling equipment suppliers to redesign sample probes by either increasing sheath diameter, altering the placement or increasing the number of thermocouples used to control the probe heating system, and/ or increasing the insulation around the sample liner. The commenter added that an increase in the diameter of the probe sheath would have a cascading effect either requiring test companies to purchase new sample hot boxes or retrofit existing sample hot boxes to accommodate the increased probe sheath diameter. Seven commenters stated that neither information nor data was provided to support, justify, or quantify the claimed increased precision of filterable PM measurements, and a few of these commenters noted that the Electric Power Research Institute (EPRI) paper that the EPA used as the basis for tightening the filter temperature tolerance was from a comparison of results measured at four coal-fired power plants. One commenter requested that the statement in § 60.50Da(b)(1)(ii)(A), ‘‘The probe and filter holder heating system in the sampling train may be set to provide an average gas temperature of no greater than 160 ±5 °C (320 ±9 °F),’’ be changed to, ‘‘The probe and filter holder heating system in the sampling train shall be set to provide an average gas temperature of 160 ±5 °C (320 ±9 °F),’’ because they believe that this was the agency’s intent. Similarly, another commenter requested that the statement in § 60.296(d)(2), ‘‘The probe and filter holder heating system may be set to provide a gas temperature no greater than 177 ±5 °C (320 ±9 °F),’’ be changed to, ‘‘The probe and filter holder heating system shall be set to provide an average gas temperature 160 ±5 °C (320 ±9 °F),’’ because they believe that this was the agency’s intent. One commenter also recommended changing the sentence in Method 5B to, ‘‘The collected sample is then heated in an oven at 160 °C (320 °F) for 6 hours . . . ,’’ to, ‘‘The collected sample is then heated in an oven at 160 ±5 °C (320 ±9 °F) for 6 hours . . .,’’ to be internally consistent. Three commenters noted that if the temperature tolerances are changed in Method 5, methods that reference Method 5 (namely Method 5D, section E:\FR\FM\14NOR1.SGM 14NOR1 Federal Register / Vol. 83, No. 220 / Wednesday, November 14, 2018 / Rules and Regulations 2.1; Method 5E, section 2.0; and Method 5F, section 2.0) would also need to be revised. Three commenters remarked that tightening the filter temperature tolerance conflicts with the assertion that the proposed rule will improve the quality of data but will not impose new substantive requirements. Two of the three commenters further remarked that the proposed rule does not meet the requirements of Executive Order 13771 nor the Paperwork Reduction Act (PRA). Three commenters acknowledged that an improvement in measurement precision could benefit the data quality in limited situations, such as the Mercury and Air Toxics Standards (MATS). Four commenters remarked that if the proposed revisions to the temperature tolerances lead to a measurable change in reported PM emissions, sources that were previously in compliance with their emission standards may become non-compliant; one commenter added that the opposite situation may occur. One commenter stated that the proposed revision may have the unintended consequence of redefining the filterable PM being measured leading to either higher or lower PM measurements as compared to sampling runs conducted with wider tolerances. Two commenters mentioned that this revision could result in a potential safety risk. One of the commenters remarked that the added weight and handling difficulties associated with airor water-cooled probes (if necessary to control the probe temperature) can increase safety risks to testing personnel, and the other commenter remarked that the proposed requirements may require the use of encapsulated probes which are heavy and cumbersome resulting in hazards. Response: In response to these comments and in a change from proposal, we are deferring finalizing proposed revisions of the temperature tolerances of probe and filter holder heating systems as part of this rulemaking. We will continue to review supporting information and data we received on the proposed rule and may propose either revisions or similar requirements as part of future rulemakings. V. 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. VerDate Sep<11>2014 18:08 Nov 13, 2018 Jkt 247001 A. Executive Order 12866: Regulatory Planning and Review and Executive Order 13563: Improving Regulation and Regulatory Review This action is not a significant regulatory action and was, therefore, not submitted to the Office of Management and Budget (OMB) for review. B. Executive Order 13771: Reducing Regulations and Controlling Regulatory Costs This action is considered an Executive Order 13771 deregulatory action. This final rule provides meaningful burden reduction by allowing regulated facilities the flexibility to use newly-approved alternative procedures for compliance demonstration purposes, which may result in lower labor costs for some facilities (e.g., allowing digital photography in lieu of manual documentation in EPA Method 22); lower compliance testing costs (e.g., additional sample storage container options now allowed by Method 26); reducing the likelihood of re-testing (e.g., revised QA requirements in Method 308); and expediting data processing (e.g., simplified calculations in Method 325B). C. Paperwork Reduction Act (PRA) This action does not impose an information collection burden under the PRA. The revisions do not substantively revise the existing information collection requirements but simply corrects, updates, and clarifies performance testing and continuous monitoring requirements. D. Regulatory Flexibility Act (RFA) I certify that this action will not have a significant economic impact on a substantial number of small entities under the RFA. In making this determination, the impact of concern is any significant adverse economic impact on small entities. An agency may certify that a rule will not have a significant economic impact on a substantial number of small entities if the rule relieves regulatory burden, has no net burden or otherwise has a positive economic effect on the small entities subject to the rule. This action will not impose emission measurement requirements beyond those specified in the current regulations, nor does it change any emission standard. We have, therefore, concluded that this action will have no net regulatory burden for all directly regulated small entities. PO 00000 Frm 00021 Fmt 4700 Sfmt 4700 56719 E. Unfunded Mandates Reform Act (UMRA) This action does not contain any unfunded mandate as described in UMRA, 2 U.S.C. 1531–1538, and does not significantly or uniquely affect small governments. The action imposes no enforceable duty on any state, local or tribal governments or the private sector. F. Executive Order 13132: Federalism This action does not have federalism implications. It will not have substantial direct effects on the states, on the relationship between the national government and the states, or on the distribution of power and responsibilities among the various levels of government. G. Executive Order 13175: Consultation and Coordination With Indian Tribal Governments This action does not have tribal implications, as specified in Executive Order 13175. This action simply corrects and updates existing testing regulations. Thus, Executive Order 13175 does not apply to this action. H. 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 action is not subject to Executive Order 13045 because it does not concern an environmental health risk or safety risk. I. Executive Order 13211: Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution or Use This action is not subject to Executive Order 13211, because it is not a significant regulatory action under Executive Order 12866. J. National Technology Transfer and Advancement Act (NTTAA) and 1 CFR part 51 This action involves technical standards. The EPA used ASTM D6216– 12 for continuous opacity monitors in Performance Specification 1. The ASTM D6216–12 standard covers the procedure for certifying continuous opacity monitors and includes design and performance specifications, test procedures, and QA requirements to ensure that continuous opacity monitors meet minimum design and calibration E:\FR\FM\14NOR1.SGM 14NOR1 Federal Register / Vol. 83, No. 220 / Wednesday, November 14, 2018 / Rules and Regulations requirements necessary, in part, for accurate opacity monitoring measurements in regulatory environmental opacity monitoring applications subject to 10 percent or higher opacity standards. The ASTM D6216–12 standard was developed and adopted by the American Society for Testing and Materials (ASTM). The standard may be obtained from https://www.astm.org or from the ASTM at 100 Barr Harbor Drive, P.O. Box C700, West Conshohocken, PA 19428–2959. K. Executive Order 12898: Federal Actions To Address Environmental Justice in Minority Populations and Low-Income Populations The EPA believes that this action is not subject to Executive Order 12898 (59 FR 7629, February 16, 1994) because it does not establish an environmental health or safety standard. This action is a technical correction to previously promulgated regulatory actions and does not have an impact on human health or the environment. L.

When the metering system is used in conjunction with a pitot tube, the system shall allow periodic checks of isokinetic rates. The average DGM temperature for use in the calculations of section 12.0 may be obtained by averaging the two temperature sensors located at the inlet and outlet of the DGM as shown in Figure 5–3 or alternatively from a single temperature sensor located at the immediate outlet of the DGM or the plenum of the DGM. * * * * * 11.2.1 Container No. 1.

For the purposes of this section, the term ‘‘constant weight’’ means a difference of no more than 0.5 mg or 1 percent of total weight less tare weight, whichever is greater, between two consecutive weighings, with no less than 6 hours of desiccation time between weighings. Alternatively, the sample may be oven dried at 104 °C (220 °F) for 2 to 3 hours, cooled in the desiccator, and weighed to a constant weight, unless otherwise specified by the Administrator. The sample may be oven dried at 104 °C (220 °F) for 2 to 3 hours.

Note the level of liquid in the container, and confirm on the analysis sheet whether leakage occurred during transport. If a noticeable amount of leakage has occurred, either void the sample or use methods, subject to the approval of the Administrator, to correct the final results. Measure the liquid in this container either volumetrically to ±1 ml or gravimetrically to ±0.5 g. Transfer the contents to a tared 250 ml beaker, and evaporate to dryness at ambient temperature and pressure. Then oven dry the probe sample at a temperature of 160 ±5 °C (320 ±9 °F) for 6 hours. Cool in a desiccator for 2 hours, and weigh to constant weight. Report the results to the nearest 0.1 mg. 11.2.3 Container No. 3.

Desiccate for 24 hours, and weigh to a constant weight. Report the results to the nearest 0.1 mg. Note: The contents of Container No. 2 as well as the acetone blank container may be evaporated at temperatures higher than ambient. If evaporation is done at an elevated temperature, the temperature must be below the boiling point of the solvent; also, to prevent ‘‘bumping,’’ the evaporation process must be closely supervised, and the contents of the beaker must be swirled occasionally to maintain an even temperature.

Precision in the range of 5 to 10 percent relative standard deviation (RSD) is typical for gas chromatographic techniques, but an experienced GC operator with a reliable instrument can readily achieve 5 percent RSD. For this method, the following combined GC/operator values are required. (a) Precision. Calibration standards must meet the requirements in section 10.2.1 or 10.2.2 as applicable. (b) Recovery. After developing an appropriate sampling and analytical system for the pollutants of interest, conduct the following spike recovery procedure at each sampling point where the method is being applied. i. Methanol Spike. Set up two identical sampling trains. Collocate the two sampling probes in the stack. The probes shall be placed in the same horizontal plane, where the first probe tip is 2.5 cm from the outside edge of the other. One of the sampling trains shall be designated the spiked train and the other the unspiked train. Spike methanol into the impinger, and onto the adsorbent tube in the spiked train prior to sampling. The total mass of methanol shall be 40 to 60 percent of the mass expected to be collected with the unspiked train. Sample the stack gas into the two trains simultaneously. Analyze the impingers and adsorbents from the two trains utilizing identical analytical procedures and instrumentation. Determine the fraction of spiked methanol recovered (R) by combining the amount recovered in the impinger and in the adsorbent tube, using the equations in section 12.5.

SUPPLEMENTARY INFORMATION: Throughout this document, the terms ‘‘we,’’ ‘‘us,’’ and ‘‘our’’ mean the EPA. I. Background II. Proposed Action and Public Comment III. Final Action IV. Statutory and Executive Order Reviews I. Background Lead is generally emitted in the form of particles that are deposited in water, soil, and dust. People may be exposed to lead by inhaling it or by ingesting lead-contaminated food, water, soil, or dust. Once in the body, lead is quickly absorbed into the bloodstream and can result in a broad range of adverse health effects including damage to the central nervous system, cardiovascular function, kidneys, immune system, and red blood cells. Children are particularly vulnerable to lead exposure, in part because they are more likely to ingest lead and in part because their still-developing bodies are more sensitive to the effects of lead. The harmful effects to children’s developing nervous systems (including their brains) arising from lead exposure may include IQ 1 loss, poor academic achievement, long-term learning disabilities, and an increased risk of delinquent behavior. The EPA first established a lead standard in 1978 at 1.5 micrograms per meter cubed (mg/m3) as a quarterly average.2 Based on new health and scientific data, the EPA revised the federal lead standard to 0.15 mg/m3 and 1 IQ (intelligence quotient) is a score created by dividing a person’s mental age score, obtained by administering an intelligence test, by the person’s chronological age, both expressed in terms of years and months. ‘‘Glossary of Important Assessment and Measurement Terms,’’ Philadelphia, PA: National Council on Measurement in Education. 2016. 2 43 FR 46246 (October 5, 1978). PO 00000 Frm 00036 Fmt 4700 Sfmt 4700 revised the averaging time for the standard on October 15, 2008.3 A violation of the standard occurs when ambient lead concentrations exceed 0.15 mg/m3 averaged over a 3-month rolling period. Following the promulgation of a new or revised NAAQS, the EPA is required by the CAA to designate areas throughout the United States as attaining or not attaining the NAAQS. This process is set forth in section 107(d)(1) of the Act. After initially being designated unclassifiable due to insufficient monitoring data, the Hayden area was redesignated nonattainment on September 3, 2014, effective October 3, 2014.4 5 The designation of the Hayden area as nonattainment for the 2008 lead NAAQS triggered requirements under section 191(a) of the CAA requiring Arizona to submit a SIP revision with a plan to attain the standard as expeditiously as practicable, but no later than October 3, 2019. The Arizona Department of Environmental Quality (ADEQ) is the air quality agency that develops SIP revisions for the Hayden area. The SIP revision for the Hayden Lead NAA, entitled ‘‘SIP Revision: Hayden Lead Nonattainment Area’’ (‘‘2017 Hayden Lead Plan’’ or ‘‘Plan’’) was adopted by ADEQ on March 3, 2017, and submitted to the EPA on the same day.6 The Plan includes a 2012 base year emissions inventory, a demonstration that controls required under the Plan are sufficient to bring the area into attainment of the 2008 lead NAAQS, an analysis that demonstrates reasonably available control measures/reasonably available control technology (RACM/RACT) levels of control are required to be implemented, a demonstration that the Plan provides for reasonable further progress (RFP) towards attainment, and a contingency measure that will be implemented if the area fails to make 3 73 FR 66964 (November 12, 2008) (‘‘lead NAAQS rule’’). 4 79 FR 52205. 5 For an exact description of the Hayden Lead NAA, see 40 CFR 81.303. 6 Letter dated March 3, 2017, from Timothy S. Franquist, Director, Air Quality Division, ADEQ, to Alexis Strauss, Acting Regional Administrator, EPA Region IX. E:\FR\FM\14NOR1.SGM 14NOR1

I. General Information

A. Does this action apply to me?

    The revisions promulgated in this final rule apply to industries 
that are subject to the current provisions of 40 Code of Federal 
Regulations (CFR) parts 51, 60, and 63. We did not list all of the 
specific affected industries or their North American Industry 
Classification System (NAICS) codes herein since there are many 
affected sources in numerous NAICS categories. If you have any 
questions regarding the applicability of this action to a particular 
entity, consult either the air permitting authority for the entity or 
your EPA Regional representative as listed in 40 CFR 63.13.

B. What action is the agency taking?

    We are promulgating corrections and updates to regulations for 
source testing of emissions. More specifically, we are correcting 
typographical and technical errors, updating obsolete testing 
procedures, adding approved testing alternatives, and clarifying 
testing requirements.

C. Judicial Review

    Under section 307(b)(1) of the Clean Air Act (CAA), judicial review 
of this final rule is available by filing a petition for review in the 
United States Court of Appeals for the District of Columbia Circuit by 
January 14, 2019. Under section 307(d)(7)(B) of the CAA, only an 
objection to this final rule that was raised with reasonable 
specificity during the period for public comment can be raised during 
judicial review. Moreover, under section 307(b)(2) of the CAA, the 
requirements that are the subject of this final rule may not be 
challenged later in civil or criminal proceedings brought by the EPA to 
enforce these requirements.

II. Background

    The revisions to testing regulations for air emission sources were 
proposed in the Federal Register on January 26, 2018 (83 FR 3636). The 
public comment period ended March 27, 2018, and 83 comment letters were 
received from the public; 23 of the comment letters were relevant, and 
the other 60 comment letters were considered beyond the scope of the 
proposed rule. This final rule was developed based on public comments 
that the agency received on the proposed rule.

III. Summary of Amendments

A. Method 201A of Appendix M of Part 51

    In Method 201A, in section 12.5, the denominator of equation 24 is 
corrected

[[Page 56715]]

as proposed; the proposed c'p in the denominator is changed 
to Cp' to be consistent with the nomenclature in section 
12.1. The cp in the numerator is changed to Cp 
also to be consistent with the nomenclature in section 12.1.

B. Method 204 of Appendix M of Part 51

    In Method 204, in section 8.2, the statement regarding equation 
204-2 is corrected to ``The NEAR must be <=0.05,'' as proposed.

C. Method 205 of Appendix M of Part 51

    In Method 205, section 2.1.1 is revised to allow the use of 
National Institute of Standards and Technology (NIST)-traceable 
transfer standards to calibrate the gas dilution system as proposed. 
The agency continues to believe that these standards are widely 
available and provide the accuracy necessary to perform the 
calibration. Section 2.1.1 is also revised as proposed to require 
testers to report the results of the calibration of the dilution system 
to enable the regulatory authority to review this information.

D. General Provisions (Subpart A) of Part 60

    In the General Provisions of part 60, Sec.  60.17(h) is revised as 
proposed to add ASTM D6216-12 to the list of incorporations by 
reference and to re-number the remaining consensus standards that are 
incorporated by reference in alpha-numeric order.

E. Fossil-Fuel-Fired Steam Generators (Subpart D) Part 60

    In a change from proposal, the allowed filter temperature in Sec.  
60.46(b)(2)(i) is not revised. Based on comments we received on the 
proposed revisions, we are deferring finalizing the proposed revisions 
of the temperature tolerances of probe and filter holder heating 
systems as part of this rulemaking. We will continue to review 
supporting information and data we received on the proposed rule and 
may propose either revisions or similar requirements as part of future 
rulemakings.

F. Electric Utility Steam Generating Units (Subpart Da) Part 60

    In a change from proposal, the allowed filter temperature in Sec.  
60.50Da (b)(1)(ii)(A) is not revised. Based on comments we received on 
the proposed revisions, we are deferring finalizing the proposed 
revisions of the temperature tolerances of probe and filter holder 
heating systems as part of this rulemaking. We will continue to review 
supporting information and data we received on the proposed rule and 
may propose either revisions or similar requirements as part of future 
rulemakings.

G. Industrial-Commercial-Institutional Steam Generating Units (Subpart 
Db) Part 60

    In a change from proposal, the allowed filter temperature in Sec.  
60.46b(d)(4) is not revised. Based on comments we received on the 
proposed revisions, we are deferring finalizing the proposed revisions 
of the temperature tolerances of probe and filter holder heating 
systems as part of this rulemaking. We will continue to review 
supporting information and data we received on the proposed rule and 
may propose either revisions or similar requirements as part of future 
rulemakings.

H. Small Industrial-Commercial-Institutional Steam Generating Units 
(Subpart Dc) Part 60

    In a change from proposal, the allowed filter temperature in Sec.  
60.45c(a)(5) is not revised. Based on comments we received on the 
proposed revisions, we are deferring finalizing the proposed revisions 
of the temperature tolerances of probe and filter holder heating 
systems as part of this rulemaking. We will continue to review 
supporting information and data we received on the proposed rule and 
may propose either revisions or similar requirements as part of future 
rulemakings.

I. Municipal Waste Combustors for Which Construction is Commenced After 
December 20, 1989 and on or Before September 20, 1994 (Subpart Ea) Part 
60

    In a change from proposal, the allowed filter temperature in Sec.  
60.58a(b)(3) is not revised. Based on comments we received on the 
proposed revisions, we are deferring finalizing the proposed revisions 
of the temperature tolerances of probe and filter holder heating 
systems as part of this rulemaking. We will continue to review 
supporting information and data we received on the proposed rule and 
may propose either revisions or similar requirements as part of future 
rulemakings.

J. Glass Manufacturing Plants (Subpart CC) Part 60

    In a change from proposal, the allowed filter temperatures in 
Sec. Sec.  60.293(f) and 60.296(d)(2) are not revised. Based on 
comments we received on the proposed revisions, we are deferring 
finalizing the proposed revisions of the temperature tolerances of 
probe and filter holder heating systems as part of this rulemaking. We 
will continue to review supporting information and data we received on 
the proposed rule and may propose either revisions or similar 
requirements as part of future rulemakings.

K. New Residential Wood Heaters, New Residential Hydronic Heaters and 
Forced-Air Furnaces (Subpart QQQQ) Part 60

    In subpart QQQQ, in Method 28WHH, in section 13.5.1, equation 8 is 
corrected as proposed.

L. Method 2B of Appendix A-1 of Part 60

    In Method 2B, in section 12.1, the definition of ambient carbon 
dioxide concentration is revised as proposed. The agency continues to 
believe that the global monthly mean (CO2)a 
concentration varies over time. Also, a website link is added to the 
definition as specified at proposal.

M. Method 5 of Appendix A-3 of Part 60

    In a change from proposal, allowed filter temperatures in Method 5, 
sections 2.0, 6.1.1.2, 6.1.1.6, 6.1.1.7, and 8.5 are not revised. Based 
on comments we received on the proposed revisions, we are deferring 
finalizing the proposed revisions of the temperature tolerances of 
probe and filter holder heating systems as part of this rulemaking. We 
will continue to review supporting information and data we received on 
the proposed rule and may propose either revisions or similar 
requirements as part of future rulemakings.
    Section 6.1.1.9 is revised as proposed to allow the use of a single 
temperature sensor in lieu of two temperature sensors on the dry gas 
meter as allowed by Technical Information Document 19 (TID-19) and the 
approved broadly applicable alternative, ALT-117 (see https://www.epa.gov/emc). Consistent with our response to the comment regarding 
allowing flexibility for the weighing container in section 11.2.1, 
Method 5B, the first sentence in section 11.2.1, Method 5 is revised 
similarly.

N. Method 5B of Appendix A-3 of Part 60

    In a change from proposal, the allowed filter temperatures in 
Method 5B, sections 2.0, 6.1, and 8.2 are not revised. Based on 
comments we received on the proposed revisions, we are deferring 
finalizing the proposed revisions of the temperature tolerances of 
probe and filter holder heating

[[Page 56716]]

systems as part of this rulemaking. We will continue to review 
supporting information and data we received on the proposed rule and 
may propose either revisions or similar requirements as part of future 
rulemakings.
    Section 11.0 is revised as proposed to replace the reference to 
Method 5, section 11.0 with specific analytical procedures and to 
report the results using Figure 5B-1 for complete data review. Section 
17.0 is revised as proposed to delete the word ``Reserved'' from the 
title, and Figure 5B-1 (Analytical Data Sheet) is added.

O. Method 5I of Appendix A-3 of Part 60

    In a change from proposal, Method 5I, sections 2.1 and 8.5.2.2 are 
not revised to tighten the allowed filter temperatures. Based on 
comments we received on the proposed revisions, we are deferring 
finalizing the proposed revisions of the temperature tolerances of 
probe and filter holder heating systems as part of this rulemaking. We 
will continue to review supporting information and data we received on 
the proposed rule and may propose either revisions or similar 
requirements as part of future rulemakings.

P. Method 7 of Appendix A-4 of Part 60

    In Method 7, sections 10.1.2 and 11.3 reference erroneous sections; 
the correct section is inserted, as proposed. The proposed referenced 
section 10.1.1.2 is changed to 10.1.1 to include procedures in both 
sections 10.1.1.1 and 10.1.1.2.

Q. Method 8 of Appendix A-4 of Part 60

    As proposed, Method 8, sections 6.1.1.1 through 6.1.1.4 are 
renumbered to 6.1.1.2 through 6.1.1.5; a new section 6.1.1.1 is added 
to clarify the requirements that apply to the probe nozzle; and, in 
response to comments, Figure 8-1 (Sulfuric Acid Sampling Train) is 
corrected by: (1) Modifying the impinger graphics to make it consistent 
with the text in section 6.1.1.4 and (2) revising the proposed label S-
Type Pitot Tube to Type S Pitot Tube for consistency. The proposed 
first sentence in section 6.1.1.1 is revised to ``Borosilicate or 
quartz glass with a sharp, tapered leading edge and coupled to the 
probe liner using a polytetrafluoroethylene (PTFE) or glass-lined union 
(e.g., fused silica, Silico, or equivalent).'' Based on a public 
comment that recommended adding Silco coated stainless steel unions as 
an option for Teflon unions, and for consistency with other test 
methods, we have replaced Teflon with the generic option 
polytetrafluoroethylene (PTFE).

R. Method 18 of Appendix A-6 of Part 60

    In Method 18, in section 13.1, the erroneous paragraph (c) 
designation is re-designated as (b), as proposed.

S. Method 22 of Appendix A-7 of Part 60

    In Method 22, sections 11.2.1 and 11.2.2 are revised as proposed to 
allow digital photography to be used for a subset of the recordkeeping 
requirements. As proposed, section 11.2.3 is added to specify the 
requirements for digital photographic records. In response to comments 
on the proposal, the next to the last sentence in section 11.2.3 
regarding photographs that must be taken within 15 minutes of the 
observation period is revised from the proposal, and another sentence 
is added to provide clarity. The revised and new sentences read: ``The 
photograph(s) representing the environmental conditions including the 
sky conditions and the position of the sun relative to the observer and 
the emission point must be taken within a reasonable time of the 
observation (i.e., 15 minutes). When observations are taken from 
exactly the same observation point on a routine basis (e.g., daily) and 
as long as there are no modifications to the units depicted, only a 
single photograph each day is necessary to document the observer's 
location relative to the emissions source, the process unit being 
observed, and the location of potential and actual emission points.'' 
The agency notes that ALT-109 (see https://www.epa.gov/emc) is the 
associated broadly applicable alternative that allows the use of 
digital photographs for specific recordkeeping requirements.

T. Method 26 of Appendix A-8 of Part 60

    As proposed, Method 26, section 6.2.2 is revised to allow the use 
of glass sample storage containers as an option to allow flexibility 
and to be consistent with Method 26A. The proposed title of section 
6.2.2, ``Storage Bottles,'' is changed to ``Storage Containers'' to be 
consistent with the language in section 6.2.2.

U. Method 26A of Appendix A-8 of Part 60

    As proposed, in Method 26A, section 6.2.1 is revised to remove the 
language regarding sample storage containers. In response to comments 
on our proposal, we have determined that high-density polyethylene is 
an acceptable material for sample storage containers in addition to the 
currently allowed glass. Therefore, in a new section 6.2.4., we have 
specified that both high-density polyethylene and glass are acceptable 
sample storage containers.

V. Test Method 28WHH of Appendix A-8 of Part 60

    In Test Method 28WHH, equation 8 in section 13.5.1 is corrected, as 
proposed.

W. Performance Specification 1 of Appendix B of Part 60

    As proposed, in Performance Specification 1, references to ASTM 
D6216-98 (in sections 2.1, 3.1, 6.1, 8.1(1), 8.1(3)(ii), 8.2(1), 
8.2(2), 8.2(3), 9.0, 12.1, 13.0, 13.1, 13.2, and 16.0 paragraph 8) are 
replaced with ASTM D6216-12. As noted at proposal, if the initial 
certification of the continuous opacity monitoring system (COMS) has 
already occurred using D6216-98, D6216-03, or D6216-07, it will not be 
necessary to recertify using D6216-12. In response to comments on our 
decision to add ASTM D6216 to the list of consensus standards, the 
April 1998 publication date for ASTM D6216 in paragraph 8 in section 
16.0 is replaced with October 2012, the ASTM D6216-12 publication date. 
In response to comments, for consistency with section 2.1, and for 
purposes of clarification, the note at the end of section 2.1 is added 
to section 13.0.

X. Performance Specification 2 of Appendix B of Part 60

    In Performance Specification 2, section 13.2 is replaced with a 
table that indicates the relative accuracy performance specifications, 
as proposed. Given that the equals to (=) signs were erroneously 
omitted from several of the < and > values during publication of the 
table in the proposed rule, these values have been corrected.

Y. Performance Specification 3 of Appendix B of Part 60

    In Performance Specification 3, the two sentences in section 12.0 
that read, ``Calculate the arithmetic difference between the RM and the 
CEMS output for each run. The average difference of the nine (or more) 
data sets constitute the RA.'' are deleted, as proposed; these two 
sentences are no longer necessary since equations 3-1 and 3-2 would be 
moved from section 13.2 to section 12.0. The sentence, ``Calculate the 
RA using equations 3-1 and 3-2.'' is added to the beginning of section 
12.0.

Z. Performance Specification 11 of Appendix B of Part 60

    In Performance Specification 11, section 13.1, the word ``average'' 
erroneously exists in the second sentence and is deleted, as proposed.

[[Page 56717]]

AA. Performance Specification 15 of Appendix B of Part 60

    As proposed, in Performance Specification 15, section 13.0 is added 
as ``Method Performance [Reserved].''

BB. Performance Specification 18 of Appendix B of Part 60

    As proposed, in Performance Specification 18, in section 11.8.7, 
the last sentence is revised to clarify the duration of the drift 
check. In Table 1, the erroneous acronym ``NO2'' is replaced 
with ``NO,'' as proposed. In the appendix of Performance Specification 
18, the inadvertently omitted reserved section 12.0 is added, as 
proposed.

CC. Procedure 1 of Appendix F of Part 60

    As proposed, in Procedure 1, in section 5.1.2 (1), the sentence 
immediately following the table that reads, ``Challenge the CEMS three 
times at each audit point, and use the average of the three responses 
in determining accuracy.'' is replaced with, ``Introduce each of the 
audit gases, three times each for a total of six challenges. Introduce 
the gases in such a manner that the entire CEMS is challenged. Do not 
introduce the same gas concentration twice in succession.'' In order to 
obtain six distinct readings during the cylinder gas audit (CGA), the 
same gas must not be introduced twice in succession, and this revised 
language accurately reflects this standard scientific practice. As also 
proposed, in section 5.1.2 (3), the reference to EPA's traceability 
protocol for gaseous calibration standards is updated, and the language 
regarding the use of EPA Method 205 for dilution of audit gases is 
clarified.

DD. General Provisions (Subpart A) of Part 63

    Sections 63.7(g)(2), 63.7(g)(2)(v), and 63.8(e)(5)(i) of the 
General Provisions (subpart A) of part 63 are revised, as proposed, to 
require the reporting of specific test data for continuous monitoring 
system performance evaluation tests and ongoing quality assurance (QA) 
tests. These data elements are required regardless of the format of the 
report, i.e., electronic or paper. These modifications will ensure that 
performance evaluation and QA test reporting include all data necessary 
for the compliance authority to assess and assure the quality of the 
reported data and that the reported information describes and 
identifies the specific unit covered by the evaluation test report. In 
response to comment, we specified the level of reporting needed for 
continuous parameter monitoring systems (CPMS) versus other continuous 
monitoring systems including continuous emission monitoring systems 
(CEMS), COMS, and predictive emissions monitoring systems (PEMS).

EE. Wool Fiberglass Manufacturing (Subpart NNN) Part 63

    In a change from proposal, the allowed filter temperature in Sec.  
63.1385(a)(5) is not revised. Based on comments we received on the 
proposed revisions, we are deferring finalizing proposed revisions of 
the temperature tolerances of probe and filter holder heating systems 
as part of this rulemaking. We will continue to review supporting 
information and data we received on the proposed rule and may propose 
either revisions or similar requirements as part of future rulemakings.

FF. Major Sources: Industrial, Commercial, and Institutional Boilers 
and Process Heaters (Subpart DDDDD) Part 63

    As proposed, in Table 6 of subpart DDDDD, row 1.f. is revised to 
allow the use of EPA SW-846-7471B (for liquid samples) in addition to 
EPA SW-846-7470A for measuring mercury to allow for compliance 
flexibility.

GG. Coal- and Oil-Fired Electric Utility Steam Generating Units 
(Subpart UUUUU) Part 63

    In a change from proposal, the allowed filter temperature in Sec.  
63.10010(h)(7)(i)(1) is not revised. Based on comments we received on 
the proposed revisions, we are deferring finalizing proposed revisions 
of the temperature tolerances of probe and filter holder heating 
systems as part of this rulemaking. We will continue to review 
supporting information and data we received on the proposed rule and 
may propose either revisions or similar requirements as part of future 
rulemakings.
    As proposed, in Table 5, Method 5I is specified as a test method 
option because, as explained at proposal, Method 5I is designed for low 
particulate matter (PM) application.

HH. Method 303 of Appendix A of Part 63

    In Method 303, section 12.4, equation 303-3 is corrected, as 
proposed, by inserting ``where y = '' in front of the equation.

II. Method 308 of Appendix A of Part 63

    As proposed, in Method 308, deionized distilled water replaces the 
aqueous n-proponal solution; the affected sections are 2.0, 7.2.2, 
7.2.3.3, and 11.3.2. Section 7.2.2, which defines the aqueous n-
proponal solution, is removed, as proposed. In section 7.2.3.3, the 
erroneous ``four'' is replaced as proposed, with ``three'' in the 
sentence that reads ``Pipette 5, 15, and 25 ml of this standard, 
respectively into four 50-ml volumetric flasks.'' Section 8.1.2 is 
revised, as proposed, to require a leak check prior to the sampling run 
(in addition to after the sampling run) for QA purposes; as explained 
at proposal, requiring a leak check prior to the sampling run would 
potentially save time and money. In section 9.1, methanol spike 
recovery check is added as a quality control (QC) measure in Table 9.1, 
as proposed. In section 12.1, variables used in equations 308-4 and 
308-5 are added and section 12.5, which includes equations 308-4 and 
308-5, is added, as proposed. In section 13.0, the title ``Reserved'' 
is replaced with ``Method Performance'' and QA requirements would be 
added to be consistent with other methods, as proposed. The erroneous 
proposed paragraph (a) of section 13.0 is replaced, as proposed, with 
``Calibration standards must meet the requirements in section 10.2.1 or 
10.2.2 as applicable.''

JJ. Method 320 of Appendix A of Part 63

    In section 8.2.2.4, the denominator in equation 2 is corrected from 
PSS to PS, as proposed. In section 9.2.3, the 
word ``where'' in the statement, ``Calculate the dilution ratio using 
the tracer gas as follows: where:'' is deleted, as proposed. Also in 
section 9.2.3, the inadvertently superscripted ``dir'' on the 
definition of spike is subscripted, as proposed.

KK. Method 323 of Appendix A of Part 63

    In Method 323, section 12.9, the denominator in equation 323-8 is 
corrected, as proposed.

LL. Method 325A of Appendix A of Part 63

    In Method 325A, section 8.2.1.3 is revised, as proposed, to clarify 
that only one extra sampling site is required near known sources of 
volatile organic compounds (VOCs) when the source is located both 
within 50 meters of the boundary and between two monitors. Based on a 
public comment we received on the proposed regulatory text, wording 
changes have been made to the language in section 8.2.1.3. As proposed, 
the label under Figure 8.1 is corrected from ``Refinery (20% angle)'' 
to ``Refinery (20[deg] angle).'' Section 8.2.3.2 is revised, as 
proposed, to include facilities with a monitoring perimeter length 
equal to 7,315 meters (24,000 feet). Section 8.2.3.3 is added, as

[[Page 56718]]

proposed, to provide clarification and an equivalent procedure in 
Option 2 (linear distance between sites) for site locations that 
parallel section 8.2.2.2.4 in Option 1 (radial distance between sites). 
In response to comments, section 8.4.3 is added to address worker 
safety during extenuating circumstances.

MM. Method 325B of Appendix A of Part 63

    In Method 325B, section 9.3.2 is revised, as proposed, to correct 
an error in the number of field blank samples required for a sampling 
period and to provide consistency with the sample analysis required in 
Method 325B. In sections 9.13 and 11.3.2.5, the erroneous reference to 
section 10.6.3 is corrected to 10.0, as proposed. Also in section 
11.3.2.5, the erroneous reference to section 10.9.5 is corrected to 
9.13, as proposed. Section 12.2.2 is revised, as proposed, to correct 
the calculation of target compound concentrations at standard 
conditions, and the erroneous reference to Ustd in the note 
in section 12.2.2 is revised to UNTP. Sections 12.2.3 and 
12.2.4 are deleted, as proposed, because the equations for target 
concentrations are incorrect. Table 17-1 is revised, as proposed, to 
add inadvertently omitted QC criteria from section 9.3.3.

IV. Public Comments on the Proposed Rule

    Eighty-three (83) comment letters were received from the public; 23 
of the comment letters were relevant, and the other 60 comment letters 
were considered as beyond the scope of the proposed rule. The public 
comments and the agency's responses are summarized in the Response to 
Comments document located in the docket for this rule. See the 
ADDRESSES section of this preamble.
    A summary of the relevant portions of significant comments that we 
received on the proposal and agency responses are presented below.
    Comment: Three commenters provided comments on our proposed 
revisions to the General Provisions (Subpart A) of Part 63. One 
commenter stated that the proposed revisions impose new requirements on 
CMS performance evaluations and QA testing for types of monitors not 
previously subject to such requirements. Another commenter remarked 
that the proposed revisions to various requirements in Part 63 
revisions were vague. Yet another commenter remarked that the proposed 
revisions to Sec.  63.8(e)(5) would shorten the CMS performance 
evaluation reporting period for CMS associated with performance tests.
    Response: We disagree with the comment that the proposed changes to 
Sec.  63.8(e)(5)(i) would impose new requirements given that at 
proposal, the agency had explained that they were intended to clarify 
and codify data elements and reporting requirements that are already 
routinely requested by the Administrator's delegated authorities. With 
regard to Sec.  63.8(e)(5), in a change from proposal, we have retained 
the existing requirement that allows for the simultaneous submission of 
the report of a CMS performance evaluation with results of performance 
testing required under 40 CFR 63.7. We also edited the final rule 
language for 40 CFR 63.7(g)(2)(v) to improve clarity and to eliminate 
confusion.
    Comment: Fifteen commenters provided comments arguing against the 
proposal to tighten the filter temperature tolerance in 40 CFR 
60.46(b)(2)(i); 60.50Da(b)(1)(ii)(A); 60.45c(a)(5); 60.58a(b)(3); 
60.293(f); 60.296(d)(2); 63.1385(a)(5); and sections 2.0, 6.1.1.2, 
6.1.1.6, 6.1.1.7 and 8.5 of Method 5, Appendix A-3 of Part 60. They 
cited issues that included: weather (e.g., ambient temperature 
fluctuations and windy conditions); costs; lack of justification and 
data for the revision; inconsistent language (e.g., the use of 
``shall'' vs. ``may'' and proposed revisions to temperature tolerance 
in Methods 5, 5B, and 5I but not in Methods 5D, 5E, and 5F); and safety 
risks. Nine commenters remarked that ambient conditions (cold climates, 
wind gusts, etc.) can cause temperature fluctuations that are difficult 
to manage. More specifically, one commenter stated that the reduced 
allowable temperature range would be problematic during testing in 
cold, windy ambient conditions that are persistent in the winter months 
in northern climates because the time required for temperature recovery 
after a component change in these conditions could add hours and 
possibly days to testing programs. One commenter remarked that the 
proposed 5 [deg]C is unattainable for sources in cold or 
windy climates.
    Eight commenters stated that alteration or replacement of equipment 
components would likely be necessary to achieve the proposed 
temperature tolerances resulting in additional costs. One commenter 
noted potential equipment improvements, such as increased probe sheath 
tubing diameter to make room for added insulation around every probe 
heater; re-design of filter heating ovens; improved sealing and 
insulation of the openings at the inlet and outlet of filter heating 
ovens; and/or for sources with high stack temperatures, more frequent 
use of air-cooled or water-cooled probes. One commenter remarked that 
this revision would force cold weather stack testers to replace or 
retrofit equipment with higher power heating devices and possibly more 
refined control devices which would be costly. One commenter remarked 
that this revision will most likely require air sampling equipment 
suppliers to redesign sample probes by either increasing sheath 
diameter, altering the placement or increasing the number of 
thermocouples used to control the probe heating system, and/or 
increasing the insulation around the sample liner. The commenter added 
that an increase in the diameter of the probe sheath would have a 
cascading effect either requiring test companies to purchase new sample 
hot boxes or retrofit existing sample hot boxes to accommodate the 
increased probe sheath diameter.
    Seven commenters stated that neither information nor data was 
provided to support, justify, or quantify the claimed increased 
precision of filterable PM measurements, and a few of these commenters 
noted that the Electric Power Research Institute (EPRI) paper that the 
EPA used as the basis for tightening the filter temperature tolerance 
was from a comparison of results measured at four coal-fired power 
plants.
    One commenter requested that the statement in Sec.  
60.50Da(b)(1)(ii)(A), ``The probe and filter holder heating system in 
the sampling train may be set to provide an average gas temperature of 
no greater than 160 5 [deg]C (320 9 [deg]F),'' 
be changed to, ``The probe and filter holder heating system in the 
sampling train shall be set to provide an average gas temperature of 
160 5 [deg]C (320 9 [deg]F),'' because they 
believe that this was the agency's intent. Similarly, another commenter 
requested that the statement in Sec.  60.296(d)(2), ``The probe and 
filter holder heating system may be set to provide a gas temperature no 
greater than 177 5 [deg]C (320 9 [deg]F),'' be 
changed to, ``The probe and filter holder heating system shall be set 
to provide an average gas temperature 160 5 [deg]C (320 
9 [deg]F),'' because they believe that this was the 
agency's intent. One commenter also recommended changing the sentence 
in Method 5B to, ``The collected sample is then heated in an oven at 
160 [deg]C (320 [deg]F) for 6 hours . . . ,'' to, ``The collected 
sample is then heated in an oven at 160 5 [deg]C (320 
9 [deg]F) for 6 hours . . .,'' to be internally consistent.
    Three commenters noted that if the temperature tolerances are 
changed in Method 5, methods that reference Method 5 (namely Method 5D, 
section

[[Page 56719]]

2.1; Method 5E, section 2.0; and Method 5F, section 2.0) would also 
need to be revised.
    Three commenters remarked that tightening the filter temperature 
tolerance conflicts with the assertion that the proposed rule will 
improve the quality of data but will not impose new substantive 
requirements. Two of the three commenters further remarked that the 
proposed rule does not meet the requirements of Executive Order 13771 
nor the Paperwork Reduction Act (PRA).
    Three commenters acknowledged that an improvement in measurement 
precision could benefit the data quality in limited situations, such as 
the Mercury and Air Toxics Standards (MATS).
    Four commenters remarked that if the proposed revisions to the 
temperature tolerances lead to a measurable change in reported PM 
emissions, sources that were previously in compliance with their 
emission standards may become non-compliant; one commenter added that 
the opposite situation may occur. One commenter stated that the 
proposed revision may have the unintended consequence of redefining the 
filterable PM being measured leading to either higher or lower PM 
measurements as compared to sampling runs conducted with wider 
tolerances.
    Two commenters mentioned that this revision could result in a 
potential safety risk. One of the commenters remarked that the added 
weight and handling difficulties associated with air- or water-cooled 
probes (if necessary to control the probe temperature) can increase 
safety risks to testing personnel, and the other commenter remarked 
that the proposed requirements may require the use of encapsulated 
probes which are heavy and cumbersome resulting in hazards.
    Response: In response to these comments and in a change from 
proposal, we are deferring finalizing proposed revisions of the 
temperature tolerances of probe and filter holder heating systems as 
part of this rulemaking. We will continue to review supporting 
information and data we received on the proposed rule and may propose 
either revisions or similar requirements as part of future rulemakings.

V. Statutory and Executive Order Reviews

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

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

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

B. Executive Order 13771: Reducing Regulations and Controlling 
Regulatory Costs

    This action is considered an Executive Order 13771 deregulatory 
action. This final rule provides meaningful burden reduction by 
allowing regulated facilities the flexibility to use newly-approved 
alternative procedures for compliance demonstration purposes, which may 
result in lower labor costs for some facilities (e.g., allowing digital 
photography in lieu of manual documentation in EPA Method 22); lower 
compliance testing costs (e.g., additional sample storage container 
options now allowed by Method 26); reducing the likelihood of re-
testing (e.g., revised QA requirements in Method 308); and expediting 
data processing (e.g., simplified calculations in Method 325B).

C. Paperwork Reduction Act (PRA)

    This action does not impose an information collection burden under 
the PRA. The revisions do not substantively revise the existing 
information collection requirements but simply corrects, updates, and 
clarifies performance testing and continuous monitoring requirements.

D. Regulatory Flexibility Act (RFA)

    I certify that this action will not have a significant economic 
impact on a substantial number of small entities under the RFA. In 
making this determination, the impact of concern is any significant 
adverse economic impact on small entities. An agency may certify that a 
rule will not have a significant economic impact on a substantial 
number of small entities if the rule relieves regulatory burden, has no 
net burden or otherwise has a positive economic effect on the small 
entities subject to the rule. This action will not impose emission 
measurement requirements beyond those specified in the current 
regulations, nor does it change any emission standard. We have, 
therefore, concluded that this action will have no net regulatory 
burden for all directly regulated small entities.

E. Unfunded Mandates Reform Act (UMRA)

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

F. Executive Order 13132: Federalism

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

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

    This action does not have tribal implications, as specified in 
Executive Order 13175. This action simply corrects and updates existing 
testing regulations. Thus, Executive Order 13175 does not apply to this 
action.

H. 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 action is not subject to 
Executive Order 13045 because it does not concern an environmental 
health risk or safety risk.

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

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

J. National Technology Transfer and Advancement Act (NTTAA) and 1 CFR 
part 51

    This action involves technical standards. The EPA used ASTM D6216-
12 for continuous opacity monitors in Performance Specification 1. The 
ASTM D6216-12 standard covers the procedure for certifying continuous 
opacity monitors and includes design and performance specifications, 
test procedures, and QA requirements to ensure that continuous opacity 
monitors meet minimum design and calibration

[[Page 56720]]

requirements necessary, in part, for accurate opacity monitoring 
measurements in regulatory environmental opacity monitoring 
applications subject to 10 percent or higher opacity standards.
    The ASTM D6216-12 standard was developed and adopted by the 
American Society for Testing and Materials (ASTM). The standard may be 
obtained from https://www.astm.org or from the ASTM at 100 Barr Harbor 
Drive, P.O. Box C700, West Conshohocken, PA 19428-2959.

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

    The EPA believes that this action is not subject to Executive Order 
12898 (59 FR 7629, February 16, 1994) because it does not establish an 
environmental health or safety standard. This action is a technical 
correction to previously promulgated regulatory actions and does not 
have an impact on human health or the environment.

L. Congressional Review Act (CRA)

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

measuring volume to within 2 percent, and related equipment, as 
shown in Figure 5-1. Other metering systems capable of maintaining 
sampling rates within 10 percent of isokinetic and of determining 
sample volumes to within 2 percent may be used, subject to the 
approval of the Administrator. When the metering system is used in 
conjunction with a pitot tube, the system shall allow periodic 
checks of isokinetic rates. The average DGM temperature for use in 
the calculations of section 12.0 may be obtained by averaging the 
two temperature sensors located at the inlet and outlet of the DGM 
as shown in Figure 5-3 or alternatively from a single temperature 
sensor located at the immediate outlet of the DGM or the plenum of 
the DGM.

container to a tared weighing container. Desiccate for 24 hours in a 
desiccator containing anhydrous calcium sulfate. Weigh to a constant 
weight, and report the results to the nearest 0.1 mg. For the 
purposes of this section, the term ``constant weight'' means a 
difference of no more than 0.5 mg or 1 percent of total weight less 
tare weight, whichever is greater, between two consecutive 
weighings, with no less than 6 hours of desiccation time between 
weighings. Alternatively, the sample may be oven dried at 104 [deg]C 
(220 [deg]F) for 2 to 3 hours, cooled in the desiccator, and weighed 
to a constant weight, unless otherwise specified by the 
Administrator. The sample may be oven dried at 104 [deg]C (220 
[deg]F) for 2 to 3 hours. Once the sample has cooled, weigh the 
sample, and use this weight as a final weight.

Method 5B-Determination of Nonsulfuric Acid Particulate Matter 
Emissions From Stationary Sources

* * * * *

11.0 Analytical Procedure

    11.1 Record and report the data required on a sheet such as the 
one shown in Figure 5B-1.
    11.2 Handle each sample container as follows:
    11.2.1 Container No. 1. Leave the contents in the shipping 
container or transfer the filter and any loose PM from the sample 
container to a tared non-reactive oven-proof container. Oven dry the 
filter sample at a temperature of 160 5 [deg]C (320 
9 [deg]F) for 6 hours. Cool in a desiccator for 2 hours, 
and weigh to constant weight. Report the results to the nearest 0.1 
mg. For the purposes of this section, the term ``constant weight'' 
means a difference of no more than 0.5 mg or 1 percent of total 
weight less tare weight, whichever is greater, between two 
consecutive weighings, with no less than 6 hours of desiccation time 
between weighings.
    11.2.2 Container No. 2. Note the level of liquid in the 
container, and confirm on the analysis sheet whether leakage 
occurred during transport. If a noticeable amount of leakage has 
occurred, either void the sample or use methods, subject to the 
approval of the Administrator, to correct the final results. Measure 
the liquid in this container either volumetrically to 1 
ml or gravimetrically to 0.5 g. Transfer the contents to 
a tared 250 ml beaker, and evaporate to dryness at ambient 
temperature and pressure. Then oven dry the probe sample at a 
temperature of 160 5 [deg]C (320 9 [deg]F) 
for 6 hours. Cool in a desiccator for 2 hours, and weigh to constant 
weight. Report the results to the nearest 0.1 mg.
    11.2.3 Container No. 3. Weigh the spent silica gel (or silica 
gel plus impinger) to the nearest 0.5 g using a balance. This step

    11.2.4 Acetone Blank Container. Measure the acetone in this 
container either volumetrically or gravimetrically. Transfer the 
acetone to a tared 250 ml beaker, and evaporate to dryness at 
ambient temperature and pressure. Desiccate for 24 hours, and weigh 
to a constant weight. Report the results to the nearest 0.1 mg.
    Note: The contents of Container No. 2 as well as the acetone 
blank container may be evaporated at temperatures higher than 
ambient. If evaporation is done at an elevated temperature, the 
temperature must be below the boiling point of the solvent; also, to 
prevent ``bumping,'' the evaporation process must be closely 
supervised, and the contents of the beaker must be swirled 
occasionally to maintain an even temperature. Use extreme care, as 
acetone is highly flammable and has a low flash point.

    10.1.2 Determination of Spectrophotometer Calibration Factor 
Kc. Add 0 ml, 2.0 ml, 4.0 ml, 6.0 ml, and 8.0 ml of the 
KNO3 working standard solution (1 ml = 100 [micro]g 
NO2) to a series of five 50-ml volumetric flasks. To each 
flask, add 25 ml of absorbing solution and 10 ml water. Add 1 N NaOH 
to each flask until the pH is between 9 and 12 (about 25 to 35 
drops). Dilute to the mark with water. Mix thoroughly, and pipette a 
25-ml aliquot of each solution into a separate porcelain evaporating 
dish. Beginning with the evaporation step, follow the analysis 
procedure of section 11.2 until the solution has been transferred to 
the 100-ml volumetric flask and diluted to the mark. Measure the 
absorbance of each solution at the optimum wavelength as determined 
in section 10.1.1. This calibration procedure must be repeated on 
each day that samples are analyzed. Calculate the spectrophotometer 
calibration factor as shown in section 12.2.
* * * * *
    11.3 Sample Analysis. Mix the contents of the flask thoroughly, 
and measure the absorbance at the optimum wavelength used for the 
standards (section 10.1.1), using the blank solution as a zero 
reference. Dilute the sample and the blank with equal volumes of 
water if the absorbance exceeds A4, the absorbance of the 
400-[micro]g NO2 standard (see section 10.1.3).

    6.1.1.1 Probe Nozzle. Borosilicate or quartz glass with a sharp, 
tapered leading edge and coupled to the probe liner using a 
polytetrafluoroethylene (PTFE) or glass-lined union (e.g., fused 
silica, Slico, or equivalent). When the stack temperature exceeds 
210 [deg]C (410 [deg]F), a leak-free ground glass fitting or other 
leak free, non-contaminating fitting must be used to couple the 
nozzle to the probe liner. It is also acceptable to use a one-piece 
glass nozzle/liner assembly. The angle of the taper shall be 
<=30[deg], and the taper shall be on the outside to preserve a 
constant internal diameter. The probe nozzle shall be of the button-
hook or elbow design, unless otherwise specified by the 
Administrator. Other materials of construction may be used, subject 
to the approval of the Administrator. A range of nozzle sizes 
suitable for isokinetic sampling should be available. Typical nozzle 
sizes range from 0.32 to 1.27 cm (\1/8\ to \1/2\ in) inside diameter 
(ID) in increments of 0.16 cm (\1/16\ in). Larger nozzles sizes are 
also available if higher volume sampling trains are used.

    11.2.1 Outdoor Location. Record the following information on the 
field data sheet (Figure 22-1): Company name, industry, process 
unit, observer's name, observer's affiliation, and date. Record also 
the estimated wind speed, wind direction, and sky condition. Sketch 
the process unit being observed, and note the observer location 
relative to the source and the sun. Indicate the potential and 
actual emission points on the sketch. Alternatively, digital 
photography as described in section 11.2.3 may be used for a subset 
of the recordkeeping requirements of this section.
    11.2.2 Indoor Location. Record the following information on the 
field data sheet (Figure 22-2): Company name, industry, process 
unit, observer's name, observer's affiliation, and date. Record as 
appropriate the type, location, and intensity of lighting on the 
data sheet. Sketch the process unit being observed, and note the 
observer location relative to the source. Indicate the potential and 
actual fugitive emission points on the sketch. Alternatively, 
digital photography as described in section 11.2.3 may be used for a 
subset of the recordkeeping requirements of this section.
    11.2.3 Digital Photographic Records. Digital photographs, 
annotated or unaltered, may be used to record and report sky 
conditions, observer's location relative to the source, observer's 
location relative to the sun, process unit being observed, potential 
emission points and actual emission points for the requirements in 
sections 11.2.1 and 11.2.2. The image must have the proper lighting, 
field of view and depth of field to properly distinguish the sky 
condition (if applicable), process unit, potential emission point 
and actual emission point. At least one digital photograph must be 
from the point of the view of the observer. The photograph(s) 
representing the environmental conditions including the sky 
conditions and the position of the sun relative to the observer and 
the emission point must be taken within a reasonable time of the 
observation (i.e., 15 minutes). When observations are taken from 
exactly the same observation point on a routine basis (i.e., daily) 
and as long as there are no modifications to the units depicted, 
only a single photograph each is necessary to document the 
observer's location relative to the emissions source, the process 
unit being observed, and the location of potential and actual 
emission points. Any photographs altered or annotated must be 
retained in an unaltered format for recordkeeping purposes.

Your daily PM CEMS internal drift checks must demonstrate that the 
daily drift of your PM CEMS does not deviate from the value of the 
reference light, optical filter, Beta attenuation signal, or other 
technology-suitable reference standard by more than 2 percent of the 
response range. If your CEMS includes diluent and/or auxiliary 
monitors (for temperature, pressure, and/or moisture) that are 
employed as a necessary part of this performance specification, you 
must determine the calibration drift separately for each ancillary 
monitor in terms of its respective output (see the appropriate 
performance specification for the diluent CEMS specification). None 
of the calibration drifts may exceed their individual specification.

    Introduce each of the audit gases, three times each for a total 
of six challenges. Introduce the gases in such a manner that the 
entire CEMS is challenged. Do not introduce the same gas 
concentration twice in succession.
    Use of separate audit gas cylinder for audit points 1 and 2. Do 
not dilute gas from audit cylinder when challenging the CEMS.
    The monitor should be challenged at each audit point for a 
sufficient period of time to assure adsorption-desorption of the 
CEMS sample transport surfaces has stabilized.
* * * * *
    (3) Use Certified Reference Materials (CRM's) (See Citation 1) 
audit gases that have been certified by comparison to National 
Institute of Standards and Technology (NIST) Standard Reference 
Materials (SRM's) or EPA Protocol Gases following the most recent 
edition of the EPA Traceability Protocol for Assay and Certification 
of Gaseous Calibration Standards (See Citation 2). Procedures for 
preparation of CRM's are described in Citation 1. Procedures for 
preparation of EPA Protocol Gases are described in Citation 2. In 
the case that a suitable audit gas level is not commercially 
available, Method 205 (See Citation 3) may be used to dilute CRM's 
or EPA Protocol Gases to the needed level. The difference between 
the actual concentration of the audit gas and the concentration 
indicated by the monitor is used to assess the accuracy of the CEMS.

Method 308--Procedure for Determination of Methanol Emission From 
Stationary Sources

* * * * *
    2.0 Summary of Method
    A gas sample is extracted from the sampling point in the stack. 
The methanol is collected in deionized distilled water and adsorbed 
on silica gel. The sample is returned to the laboratory where the 
methanol in the water fraction is separated from other organic 
compounds with a gas chromatograph (GC) and is then measured by a 
flame ionization detector (FID). The fraction adsorbed on silica gel 
is extracted with deionized distilled water and is then separated 
and measured by GC/FID.

    7.2.3.3 Methanol Standards for Adsorbent Tube Samples. Prepare a 
series of methanol standards by first pipetting 10 ml of the 
methanol working standard into a 100-ml volumetric flask and 
diluting the contents to exactly 100 ml with deionized distilled 
water. This standard will contain 10 [micro]g/ml of methanol. 
Pipette 5, 15, and 25 ml of this

[[Page 56731]]

standard, respectively, into three 50-ml volumetric flasks. Dilute 
each solution to 50 ml with deionized distilled water. These 
standards will have 1, 3, and 5 [micro]g/ml of methanol, 
respectively. Transfer all four standards into 40-ml glass vials 
capped with Teflon[supreg]-lined septa and store under 
refrigeration. Discard any excess solution.
* * * * *
    8.1.2 Leak Check. A leak check before and after the sampling run 
is mandatory. The leak-check procedure is as follows:
    Temporarily attach a suitable (e.g., 0- to 40-ml/min) rotameter 
to the outlet of the DGM, and place a vacuum gauge at or near the 
probe inlet. Plug the probe inlet, pull a vacuum of at least 250 mm 
(10 inch) Hg or the highest vacuum experienced during the sampling 
run, and note the flow rate as indicated by the rotameter. A leakage 
rate in excess of 2 percent of the average sampling rate is 
acceptable.

    Note: Carefully release the probe inlet plug before turning off 
the pump.

    13.0 Method Performance
    Since a potential sample may contain a variety of compounds from 
various sources, a specific precision limit for the analysis of 
field samples is impractical. Precision in the range of 5 to 10 
percent relative standard deviation (RSD) is typical for gas 
chromatographic techniques, but an experienced GC operator with a 
reliable instrument can readily achieve 5 percent RSD. For this 
method, the following combined GC/operator values are required.
    (a) Precision. Calibration standards must meet the requirements 
in section 10.2.1 or 10.2.2 as applicable.
    (b) Recovery. After developing an appropriate sampling and 
analytical system for the pollutants of interest, conduct the 
following spike recovery procedure at each sampling point where the 
method is being applied.
    i. Methanol Spike. Set up two identical sampling trains. 
Collocate the two sampling probes in the stack. The probes shall be 
placed in the same horizontal plane, where the first probe tip is 
2.5 cm from the outside edge of the other. One of the sampling 
trains shall be designated the spiked train and the other the 
unspiked train. Spike methanol into the impinger, and onto the 
adsorbent tube in the spiked train prior to sampling. The total mass 
of methanol shall be 40 to 60 percent of the mass expected to be 
collected with the unspiked train. Sample the stack gas into the two 
trains simultaneously. Analyze the impingers and adsorbents from the 
two trains utilizing identical analytical procedures and 
instrumentation. Determine the fraction of spiked methanol recovered 
(R) by combining the amount recovered in the impinger and in the 
adsorbent tube, using the equations in section 12.5. Recovery values 
must fall in the range: 0.70 <= R <= 1.30. Report the R value in the 
test report.

Method 325A--Volatile Organic Compounds From Fugitive and Area Sources: 
Sampler Deployment and VOC Sample Collection

* * * * *
    8.2.1.3 An extra sampler must be placed near known sources of 
VOCs if potential emission sources are within 50 meters (162 feet) 
of the boundary and the source or sources are located between two 
monitors. Measure the distance (x) between the two monitors and 
place another monitor approximately halfway between (x/2 10 percent) the two monitors. Only one extra sampler is 
required between two monitors to account for known sources of VOCs. 
For example, in Figure 8.1, the facility added three additional 
monitors (i.e., light shaded sampler locations), and in Figure 8.2, 
the facility added two additional monitors to provide sufficient 
coverage of all area sources.

    8.2.3.2 For facilities with a monitoring perimeter length 
greater than or equal to 7,315 meters (24,000 feet), sampling 
locations are spaced 610  76 meters (2,000  
250 feet) apart.
    8.2.3.3 Unless otherwise specified in an applicable regulation, 
permit or other requirement, for small disconnected subareas with 
known sources within 50 meters (162 feet) of the monitoring 
perimeter, sampling points need not be placed closer than 152 meters 
(500 feet) apart as long as a minimum of 3 monitoring locations are 
used for each subarea.
* * * * *
    8.4.3 When extenuating circumstances do not permit safe 
deployment or retrieval of passive samplers (e.g., extreme weather, 
power failure), sampler placement or retrieval earlier or later than 
the prescribed schedule is allowed but must occur as soon as safe 
access to sampling sites is possible.

Method 325B--Volatile Organic Compounds From Fugitive and Area Sources: 
Sampler Preparation and Analysis

* * * * *
    9.3.2 Field blanks must be shipped to the monitoring site with 
the sampling tubes and must be stored at the sampling location 
throughout the monitoring exercise. The field blanks must be 
installed under a protective hood/cover at the sampling location, 
but the long-term storage caps must remain in place throughout the 
monitoring period (see Method 325A). The field blanks are then 
shipped back to the laboratory in the same container as the sampled 
tubes. Collect at least two field blank samples per sampling period 
to ensure sample integrity associated with shipment, collection, and 
storage.
* * * * *
    9.13 Routine CCV at the Start of a Sequence. Run CCV before each 
sequence of analyses and after every tenth sample to ensure that the 
previous multi-level calibration (see section 10.0) is still valid.
* * * * *
    11.3.2.5 Whenever the thermal desorption--GC/MS analytical 
method is changed or major equipment maintenance is performed, you 
must conduct a new five-level calibration (see section 10.0). System 
calibration remains valid as long as results from subsequent CCV are 
within 30 percent of the most recent 5-point calibration (see 
section 9.13). Include relevant CCV data in the supporting 
information in the data report for each set of samples.
* * * * *
    12.2.2 Determine the equivalent concentrations of compounds in 
atmospheres as follows. Correct target compound concentrations 
determined at the sampling site temperature and atmospheric pressure 
to standard conditions (25 [deg]C and 760 mm mercury) using Equation 
12.5.
[GRAPHIC] [TIFF OMITTED] TR14NO18.071

Where:

mmeas = The mass of the compound as measured in the sorbent 
tube ([micro]g).
t = The exposure time (minutes).
tss = The average temperature during the collection period 
at the sampling site (K).
UNTP = The method defined diffusive uptake rate (sampling 
rate) (mL/min).

    Note: Diffusive uptake rates (UNTP) for common VOCs, 
using carbon sorbents packed into sorbent tubes of the dimensions 
specified in section 6.1, are listed in Table 12.1. Adjust analytical 
conditions to keep expected sampled masses within range (see sections 
11.3.1.3 to 11.3.1.5). Best possible method detection limits are 
typically in the order of 0.1 ppb for 1,3-butadiene and 0.05 ppb for 
volatile aromatics such as benzene for 14-day monitoring. However, 
actual detection limits will depend upon the analytical conditions 
selected.
