AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule; correction.

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

SUMMARY: This document corrects certain preamble and regulatory text. 
This action corrects typographical errors, such as cross-reference 
errors and certain preamble text that is not consistent with the final 
regulatory text, which published in the Federal Register on Thursday, 
February 16, 2012 (77 FR 9304).

DATES: Effective date: April 19, 2012.

FOR FURTHER INFORMATION CONTACT: For the NESHAP action: Mr. William 
Maxwell, Energy Strategies Group, Sector Policies and Programs 
Division, (D243-01), Office of Air Quality Planning and Standards, U.S. 
Environmental Protection Agency, Research Triangle Park, North Carolina 
27711; Telephone number: (919) 541-5430; Fax number (919) 541-5450; 
email address: maxwell.bill@epa.gov. For the new source performance 
standard (NSPS) action: Mr. Christian Fellner, Energy Strategies Group, 
Sector Policies and Programs Division, (D243-01), Office of Air Quality 
Planning and Standards, U.S. Environmental Protection Agency, Research

Fax number (919) 541-5450; email address: fellner.christian@epa.gov.

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. Table 5 on page 9368 is corrected to read as follows:

\a\ Includes Hg.

    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 Sec.  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 
``Sec. '' symbol which was inadvertently left off of the references to 
section 63.10042 (i.e., ``63.10042'' vs. the correct ``Sec.  
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).

[[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 10\6\) and from megawatts (MW) to gigawatts (GW) (i.e., the 
correct 10-3 rather than the incorrect 10\3\). 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).

[[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, Federal Register 
document containing ``National Emission Standards for Hazardous Air 
Pollutants from Coal- and Oil-fired Electric Utility Steam Generating 
Units and Standards of Performance for Fossil-Fuel-Fired Electric 
Utility, Industrial-Commercial-Institutional, and Small Industrial-
Commercial-Institutional Steam Generating Units.''

    (g) If you use a Hg CEMS or a sorbent trap monitoring system, you 
must install, certify, operate, maintain and quality-assure the data 
from the monitoring system in accordance with appendix A to this 
subpart. You must calculate and record a 30- (or, if alternate 
emissions averaging is used, 90-) boiler operating day rolling average 
Hg emission rate, in units of the standard, updated after each new 
boiler operating day. Each 30- (or, if alternate emissions averaging is 
used, 90-) boiler operating day rolling average emission rate, 
calculated according to section 6.2 of appendix A to the subpart, is 
the average of all of the valid hourly Hg emission rates in the 
preceding 30- (or, if alternate emissions averaging is used, a 90-) 
boiler operating days. Section 7.1.4.3 of appendix A to this subpart

demonstrate continuous compliance by using all quality-assured hourly 
data recorded by the CEMS (or sorbent trap monitoring system) and the 
other required monitoring systems (e.g., flow rate, CO2, 
O2, or moisture systems) to calculate the arithmetic average 
emissions rate in units of the standard on a continuous 30-boiler 
operating day (or, if alternate emissions averaging is used for Hg, 90-

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 Sec.  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 
Sec.  63.10009(a)(2). Use Equation A-5 of this section to calculate 
the Hg emission rate for each averaging period.

Where:

Eo = 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: Do not include non-operating hours with zero emission rates 
in the average).
* * * * *
    7.2.4 Certification, Recertification, and Quality-Assurance Test 
Reporting. Except for daily QA tests of the required monitoring systems 
(i.e., calibration error tests and flow monitor interference checks), 
the results of all required certification, recertification, and 
quality-assurance tests described in paragraphs 7.1.9.1 through 7.1.9.7 
of this section (except for test results previously submitted, e.g., 
under the ARP) shall be submitted electronically, using the ECMPS 
Client Tool, either prior to or concurrent with the relevant quarterly 
electronic emissions report.
* * * * *
    7.2.5.3.4 The results of all daily calibration error tests of the 
Hg CEMS, as described in paragraph 7.1.9.1 of this section and (if 
applicable) the results of all daily flow monitor interference checks.
