SUPPLEMENTARY INFORMATION: This document corrects certain preamble and regulatory text. It is proper to issue this final rule correction without notice and comment. Section 553 of the Administrative Procedure Act (APA), 5 U.S.C. 553(b)(B), provides that, when an agency for good cause finds that notice and public procedure are impracticable, unnecessary, or contrary to the public interest, the agency may issue a rule without providing notice and an opportunity for public comment. We have determined that there is good cause for making this action final without prior proposal and opportunity for comment because the changes to the rule are minor technical corrections, are noncontroversial, and do not substantively change the agency actions taken in the final rule. Notice and comment is unnecessary, because these changes do not affect the rights or obligations of outside parties, and do not alter the substantive requirements of the code of federal regulations (CFR), except to the extent that one regulatory provision included an inadvertent typographical error that EPA must amend to align with the plain text of the Clean Air Act (CAA). We find that this constitutes good cause under 5 U.S.C. 553(b)(B).The corrections can be categorized generally as follows: Correction of typographical errors (e.g., cross-reference errors) and correction of certain preamble text that does not conform to the final regulatory text. Below, we identify each technical correction to the preamble and regulatory text. 1.

 The output-format values for the antimony and beryllium emission limits for existing solid oil-derived fuel-fired units were incorrect as published in the preamble to the final rule (i.e., the incorrect “8.0E-3 lb/GWh” instead of the correct “7.0E-3 lb/GWh” for antimony and the incorrect “6.0E-4 lb/GWh” instead of the correct “5.0E-4 lb/GWh” for beryllium). In addition, the format of the input- and output-based lead emissions limits for existing IGCC EGUs was incorrect as published in the preamble to the final rule (i.e., the incorrect “1.9E+2 lb/MMBtu or 1.8E0 lb/MWh” instead of the correct “1.9E+2 lb/TBtu or 1.8E0 lb/GWh”). In each case, the correct values are indicated in the spreadsheets found in docket entry EPA-HQ-OAR-2009-0234-20132 and the published values were transcription errors. This same correction is made to the regulatory text later in this document. 2. On page 9401, column 1, first full paragraph, the fourth sentence is corrected to read as follows: “This subcategory applies only to oil-fired EGUs that act as peaking units, as they generally address reliability issues.” We are revising this sentence because the original sentence in the preamble to the final rule stated: “This subcategory applies only to oil-fired EGUs 
                    *that operate on oil alone*
                     and act as peaking units, as they generally address reliability issues.” (emphasis added). The italicized language is not consistent with the regulatory definition of “oil-fired EGU” or the definition of “limited-use liquid oil-fired subcategory” because it incorrectly indicates that the subcategory applies only to oil-fired EGUs that operate on oil alone. See 40 CFR 63.10042. 3. The definition of “Boiler operating day” in § 60.41Da Definitions, the date “February 29, 2005” is corrected to read “March 1, 2005” because there was no February 29 in 2005. 4. Section 60.49Da(a)(4)(i) is revised to correct the typographical error related to the incorrect cross reference to section 60.51a(d) which does not exist. The correct cross reference is to section 60.51Da(d). 5. Sections 63.9982(a)(1) and (a)(2) are revised to include the “§” symbol which was inadvertently left off of the references to section 63.10042 (i.e., “63.10042” vs. the correct “§ 63.10042”. 6. Section 63.9982(d) is revised to correct the typographical error which left out the word “in” from the phrase “* * * change in process * * *” 7. Section 63.9985(a)(2) is revised to remove the words “or modification.” We erroneously included this language in the final rule definition of a new source for purposes of the NESHAP. The language included in the final rule comes from the CAA section 111 statutory definition for “new source,” instead of the CAA section 112 definition of “new source.” CAA section 112 does not include “modified” sources in the definition of new sources, and, thus, the inclusion of such sources in the definition was an inadvertent drafting error. 8. Section 63.9991(c) is revised to remove the term “coal-fired” from the phrase “coal-fired EGU.” This section expressly references Tables 1 and 2 of this subpart and those tables include alterative sulfur dioxide (SO2) limits for all EGUs meeting the requirements of section 63.9991(c), not just coal-fired EGUs. Thus, the provision as written in the final rule was incorrectly limited to coal-fired EGUs. 9. Section 63.10000(c)(1) is revised to include integrated gasification combined cycle (IGCC) EGUs among the subcategories listed. Section 63.10000(c) addresses initial performance testing. IGCC EGUs are included in the requirements of section 63.10000(c)(1)(i) (which deals with initial performance testing for purposes of determining low emitting EGU (LEE) status) and, thus, the omission of IGCC EGUs from the introductory language in section 63.10000(c)(1) was an inadvertent error. 10. Section 63.10000(c)(1)(i)(B) is revised to correct a typographical error (“* * * solid oil-derived fuel-fired * * *” rather than the incorrect “* * * solid oil-fired fuel-fired * * *”). 11. Section 63.10000(c)(2)(iv) is revised to correct a typographical error and include “you” in the phrase “* * * but you must * * *” 12. Section 63.10000(d)(5)(i) is revised to correct the typographical error of including the incorrect term “CEMS” rather than the correct term “CMS.” The text of sections 63.10000(d)(2)(i), (3), and (4) all refer to the broader “CMS” (which includes both continuous parameter monitoring system (CPMS) and continuous emission monitoring system (CEMS)). Thus, use of the narrower CEMS in section 63.10000(d)(5)(i) was an inadvertent error. Further, the term “CPMS” in the last sentence of the section is corrected to read “PM CPMS” consistent with section 63.10010(h), which section is referenced in section 63.10000(d)(5)(i) and specifically addresses PM CPMS. 13. Section 63.10000(d)(5)(iv) is revised to use language consistent with section 63.8(d) (changing “ongoing data quality assurance procedures” to “quality control program”), as section 63.8 is cited in this section. The title of section 63.8(d) is “quality control program” and the phrase “ongoing data quality assurance procedures” does not appear in that provision. 14. Section 63.10000(f) is revised to correct a typographical error by replacing “distributions system” with the correct “distribution system.” 15. Section 63.10005(b)(2) is revised to correct a typographical error by changing “* * * valid data CMS data * * *” to “valid CMS data”. 16. Section 63.10005(d)(1) is revised to correct a typographical error (the correct “* * * Table 1 or 2 to this * * *” rather than the incorrect “* * * Table 1 or 2 of this * * *” in two places).
                    ( print page 23401) 17. Section 63.10005(d)(4)(ii) is revised to correct the typographical error associated with the use of “corresponding” rather than the correct word “corresponds.” 18. Sections 63.10005(h)(3)(iii)(C)(
                    *1*) and (
                    *2*
                    ) are revised to correct the typographical errors associated with the conversion factors from million British thermal units per hour (MMBtu/hr) to trillion Btu/hr (TBtu/hr) (i.e., the correct 10−6
                     rather than the incorrect 106
                    ) and from megawatts (MW) to gigawatts (GW) (i.e., the correct 10−3
                     rather than the incorrect 103
                    ). The exponents as published are technically incorrect and the conversions would not work as published. 19. Section 63.10006(a) is revised to correct a typographical error. Specifically, we inadvertently omitted the word “fired” from the phrase “* * * solid oil-derived fuel- and * * *” The phrase should read “* * * solid oil-derived fuel-fired and * * *” 20. Section 63.10007(c) is revised to correct the typographical error associated with the incorrect cross reference to the non-existent section 63.10011(b)(5). The correct cross reference is to section 63.10011(b). 21. Section 63.10009(g) is revised to correct the typographical error related to the incorrect cross reference to sections 63.10009(f)(1) through (3). Section 63.10009(g) deals with determining weighted average emission rates, but section 63.10009(f) deals with demonstrating eligibility for an emissions averaging group and is, thus, an incorrect cross reference. The correct cross reference is to sections 63.10009(g)(1) through (2), which sections provide specific direction on the manner in which sources establish weighted average emission rates. 22. Section 63.10009(j)(2)(i)(A) is revised to correct the typographical error related to the incorrect cross reference to section 63.10009(h)(1), which does not exist. The correct cross reference is to section 63.10009(j)(1). 23. Sections 63.10010(a)(6)(iii) and (iv) are revised to correct the typographical errors related to the incorrect cross references to sections 63.10010(a)(5)(iii)(B) and (a)(5)(iii)(C), which do not exist. The correct cross references are to sections 63.10010(a)(6)(ii) and (iii), respectively. 24. Sections 63.10010(g), 63.10011(c)(1), 63.10021(b), and 63.10022(a)(1) are revised to correct the inadvertent omission of the alternate 90-day averaging period. The provisions as included in the final rule only referred to the 30-day averaging periods that are generally utilized for determining compliance with the final standards; however, as indicated in section 63.10009(a)(2), sources are also authorized to use the alternate 90-day averaging period for certain standards when emissions averaging is employed at a facility. 25. Section 63.10020(d) is revised to correct a typographical error by replacing “of” with “from” in the phrase “* * * deviation from the * * *” 26. Section 63.10030(e)(7)(i) is revised to correct the typographical error related to the incorrect cross reference to section 63.10006(i). Section 63.10006(i) addresses the tune-up requirement, but section 63.10030(e)(7)(i) concerns LEE requirements, not tune-up requirements. The correct cross reference is to section 63.10006(b), which addresses the reduced performance (i.e., stack) testing for LEE, which allows a source to test every 3 years as discussed in section 63.10030(e)(7)(i). 27. Section 63.10031(c)(4) is revised to correct an incorrect statement. The final rule does not require annual inspections; thus, the “annual” has been replaced with “every 36 (or 48) months” to be consistent with other rule text. 28. The definitions of “Non-mercury (Hg) HAP metals” and “Oil” in section 63.10042 are revised to correct the typographical error that did not separate the two definitions in the published rule. 29. Table 2 to Subpart UUUUU of Part 63 is revised to correct the typographical errors related to the lack of a superscript for footnotes (“2
                    ”) denoting “gross electric output” for filterable particulate matter emissions from “2. Coal-fired unit low rank virgin coal,” “3. IGCC,” “4. Liquid oil-fired unit—continental (excluding limited-use liquid oil-fired subcategory units),” “Liquid oil-fired unit—non-continental (excluding limited-use liquid oil-fired subcategory units),” and “6. Solid oil-derived fuel-fired unit.” In addition, the format of the input- and output-based lead emissions limits for “3. IGCC unit” was incorrect as published (i.e., the incorrect “1.9E+2 lb/MMBtu or 1.8E0 lb/MWh” instead of the correct “1.9E+2 lb/TBtu or 1.8E0 lb/GWh”). Further, the output-format values for the antimony and beryllium emission limits for “6. Solid oil-derived fuel-fired unit” were incorrect as published (i.e., the incorrect “8.0E-3 lb/GWh” instead of the correct “7.0E-3 lb/GWh” for antimony and the incorrect “6.0E-4 lb/GWh” instead of the correct “5.0E-4 lb/GWh” for beryllium). In each case, the correct values are indicated in the spreadsheets found in docket entry EPA-HQ-OAR-2009-0234-20132 and the published values are transcription errors. 30. For the reasons described in Paragraph 24 above, Table 7 to Subpart UUUUU of Part 63 is revised to address the inadvertent omission of the alternate 90-day averaging period that is available. 31. For the reasons described in Paragraph 24 above, Paragraphs 6.2.1.4 and 6.2.2.3 to Appendix A to Subpart UUUUU of Part 63 are revised to address the inadvertent omission of the alternate 90-day averaging period that is available. 32. Paragraph 7.2.4 to Appendix A to Subpart UUUUU of Part 63 is revised to correct the typographical error related to the incorrect cross reference to paragraphs 7.1.10.1 through 7.1.10.7; these paragraphs do not exist, however. The correct cross reference is paragraphs 7.1.9.1 through 7.1.9.7. 33. Paragraph 7.2.5.3.4 to Appendix A to Subpart UUUUU of Part 63 is revised to correct the typographical error related to the incorrect cross reference to paragraph 7.1.90.1; this paragraph does not exist, however. The correct cross reference is paragraph 7.1.9.1. Statutory and Executive Order Reviews Under Executive Order (EO) 12866, Regulatory Planning and Review (58 FR 51735, October 4, 1993), this action is not a “significant regulatory action” and is therefore not subject to review by the Office of Management and Budget (OMB). This action is not a “major rule” as defined by 5 U.S.C. 804(2). The technical corrections do not impose an information collection burden under the provisions of the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 
                    *et seq.*). Because EPA has made a “good cause” finding that this action is not subject to notice and comment requirements under the APA or any other statute, it is not subject to the regulatory flexibility provisions of the Regulatory Flexibility Act (5 U.S.C. 601 
                    *et seq.*), or to sections 202 and 205 of the Unfunded Mandates Reform Act of 1995 (UMRA) (Pub. L. 104-4). In addition, this action does not significantly or uniquely affect small governments or impose a significant intergovernmental mandate, as described in sections 203 and 204 of the UMRA. The corrections do not have substantial direct effects on the states, or on the relationship between the national government and the states, or on the distribution of power and responsibilities among the various levels of government, as specified in EO 13132, Federalism (64 FR 43255, August 10, 1999).
                    ( print page 23402) This action also does not significantly or uniquely affect the communities of tribal governments, as specified by EO 13175, Consultation and Coordination with Indian Tribal Governments (65 FR 67249, November 9, 2000). The technical corrections also are not subject to EO 13045, Protection of Children from Environmental Health and Safety Risks (62 FR 19885, April 23, 1997) because this action is not economically significant. The corrections are not subject to EO 13211, Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use (66 FR 28355, May 22, 2001) because this action is not a significant regulatory action under EO 12866. The corrections do not involve changes to the technical standards related to test methods or monitoring methods; thus, the requirements of section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272) do not apply. The corrections also do not involve special consideration of environmental justice-related issues as required by EO 12898, Federal Actions to Address Environmental Justice in Minority Populations and Low-Income Populations (59 FR 7629, February 16, 1994). The Congressional Review Act, 5 U.S.C. 801 
                    *et seq.,*
                     as added by the Small Business Regulatory Enforcement Fairness Act of 1996 (SBREFA), generally provides that before a rule may take effect, the agency promulgating the rule must submit a rule report, which includes a copy of the rule, to each House of the Congress and to the Comptroller General of the U.S. The EPA submitted a report containing the final action and other required information to the U.S. Senate, the U.S. House of Representatives, and the Comptroller General of the U.S. This action is not a “major rule” as defined by 5 U.S.C. 804(2). The final rule will be effective on April 16, 2012. The EPA's compliance with the above statutes and EOs for the underlying rule is discussed in the February 16, 2012,

 Accordingly, title 40, chapter I, of the Code of the Federal Regulations is amended by making the following correcting amendments: PART 60—[AMENDED]
 1.The authority citation for part 60 continues to read as follows: Authority:
                        42 U.S.C. 7401 et seq. 2.In § 60.41Da, revise the definition of “Boiler operating day” to read as follows: § 60.41Da
  
 *Boiler operating day*
                             for units constructed, reconstructed, or modified before March 1, 2005, means a 24-hour period during which fossil fuel is combusted in a steam-generating unit for the entire 24 hours. For units constructed, reconstructed, or modified after February 28, 2005, 
                            *boiler operating day*
                             means a 24-hour period between 12 midnight and the following midnight during which any fuel is combusted at any time in the steam-generating unit. It is not necessary for fuel to be combusted the entire 24-hour period.

 23.In Appendix A to Subpart UUUUU of Part 63, revise paragraphs 6.2.1.4, 6.2.2.3, 7.2.4, 7.2.5.3.4, to read as follows: Appendix A to Subpart UUUUU—Hg Monitoring Provisions 
 6.2.1.4 The heat input-based Hg emission rate limit in Table 2 to this subpart must be met on a 30 boiler operating day rolling average basis, except as otherwise provided in § 63.10009(a)(2). Use Equation 19-19 in EPA Method 19 to calculate the Hg emission rate for each averaging period. The term Ehj
                             in Equation 19-19 must be in the units of the applicable emission limit. Do not include non-operating hours with zero emissions in the average. 
 6.2.2.3 The applicable electrical output-based Hg emission rate limit in Table 1 or 2 to this subpart must be met on a 30-boiler operating day rolling average basis, except as otherwise provided in § 63.10009(a)(2). Use Equation A-5 of this section to calculate the Hg emission rate for each averaging period.
 Where: *E*̄o
                             = Hg emission rate for the averaging period (lb/GWh). Echo
                             = Electrical output-based hourly Hg emission rate for unit or stack operating hour “h” in the averaging period, from Equation A-4 of this section (lb/GWh). n = Number of unit or stack operating hours in the averaging period in which valid data were obtained for all parameters. (
                            *Note:*
