Standards of Performance for New Stationary Sources and Emissions 
Guidelines for Existing Sources: Hospital/Medical/Infectious Waste 
Incinerators

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule; amendments.

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

SUMMARY: On October 6, 2009, EPA promulgated its response to the remand 
of the new source performance standards and emissions guidelines for 
hospital/medical/infectious waste incinerators by the U.S. Court of 
Appeals for the District of Columbia Circuit and satisfied the Clean 
Air Act Section 129(a)(5) requirement to conduct a review of the 
standards every five years. This action proposes to amend the new 
source performance standards in order to correct inadvertent drafting 
errors in the emissions limits for nitrogen oxides and sulfur dioxide 
promulgated for large hospital/medical/infectious waste incinerators, 
which did not correspond to our description of our standard-setting 
process. This action will also correct erroneous cross-references in 
the reporting and recordkeeping requirements.

DATES: Comments. Comments must be received on or before June 28, 2010. 
Because of the need to revise the new source performance standards 
(NSPS) emissions limits and reporting and recordkeeping requirements in 
a timely manner, EPA will not grant requests for extensions beyond this 
date.
    Public Hearing. If anyone contacts EPA by May 24, 2010 requesting 
to speak at a public hearing, EPA will hold a public hearing on June 1, 
2010.

exchange in various areas of air pollution control.

II. Background

    On September 15, 1997, EPA adopted NSPS (40 CFR part 60, subpart 
Ec) and EG (40 CFR part 60, subpart Ce) for HMIWI under the authority 
of Sections 111 and 129 of the Clean Air Act (CAA). Emissions standards 
were adopted for the nine pollutants required to be regulated under CAA 
Section 129--particulate matter, lead, cadmium, mercury, chlorinated 
dibenzo-p-dioxins/dibenzofurans, carbon monoxide, nitrogen oxides, 
hydrogen chloride and sulfur dioxide. The EPA developed emissions 
limits for all nine pollutants for three HMIWI size subcategories 
(large, medium and small) for the NSPS and four HMIWI size 
subcategories (large, medium, small and small rural) for the EG.
    On November 14, 1997, the Sierra Club and the Natural Resources 
Defense Council (Sierra Club) filed suit in the U.S. Court of Appeals 
for the District of Columbia Circuit (the Court). The Sierra Club 
claimed that EPA violated CAA Section 129 by setting emissions 
standards for HMIWI that are less stringent than required by Section 
129(a)(2); that EPA violated Section 129 by not including pollution 
prevention or waste minimization requirements; and that EPA had not 
adequately considered the non-air quality health and environmental 
impacts of the standards.
    On March 2, 1999, the Court issued its opinion in Sierra Club v. 
EPA, 167 F.3d 658 (D.C. Cir. 1999). While the Court rejected the Sierra 
Club's statutory arguments under CAA Section 129, the Court remanded 
the rule to EPA for further explanation regarding how EPA derived the 
maximum achievable control technology (MACT) floors for new and 
existing HMIWI. The Court did not vacate the regulations, and the 
regulations remained in effect during the remand.
    On October 6, 2009, EPA promulgated its response to the Court's 
remand of the HMIWI regulations and also satisfied its requirement 
under CAA Section 129(a)(5) to conduct a five-year review of the HMIWI 
standards. The promulgated rule revised the NSPS and EG emissions 
limits for all nine of the CAA Section 129 pollutants.
    Following promulgation of the revised emissions limits, an industry 
representative informed EPA of an error in the published NSPS emissions 
limit for nitrogen oxides (NOX) for large HMIWI, which did 
not appear to reflect EPA's described analytical process for adopting 
the revised standards. On review, EPA staff determined that the 
published revised NOX NSPS for large HMIWI indeed did not 
reflect EPA's intent in the final rule. EPA also reviewed the other 
published NSPS and EG emissions limits for similar errors, and 
determined that the published revised sulfur dioxide (SO2) 
NSPS for large HMIWI also did not reflect EPA's intent in the final 
rule. To correct these errors, this action issues proposed amendments 
to the NSPS emissions limits for NOX and SO2 for 
large HMIWI.
    Also after promulgation, a State agency representative informed EPA 
of an error in the published NSPS reporting and recordkeeping 
requirements, which incorrectly referred to Sec.  60.56, instead of 
Sec.  60.56c, in three separate paragraphs. To correct this error, this 
action issues proposed amendments to the NSPS reporting and 
recordkeeping provisions that have this incorrect cross-reference.

III. Summary of Proposed Amendments

    The NSPS emissions limits for new and reconstructed HMIWI were 
developed in accordance with the criteria specified in CAA Section 
129(a)(2), which provides that the ``degree of reduction in emissions 
that is deemed achievable [* * *] shall not be less stringent than the 
emissions control that is achieved in practice by the best controlled 
similar unit, as determined by the Administrator.''
    In order to properly account for variability in the data, we 
calculated upper limits associated with the data for the best 
controlled similar unit (best performer), prior to setting the 
emissions limits. We would typically take into account the distribution 
of the emissions data (i.e., determine whether the data are distributed 
normally or lognormally) prior to calculating the upper limit value. 
Where there were a sufficient number of datapoints for the best 
performer, we used the skewness of the data to determine the 
distribution. Because normal distributions typically have a skewness of 
zero, we concluded that those datasets with a skewness less than 0.5 
were normally distributed, while those with a skewness of 0.5 or 
greater were lognormally distributed. Where there were only a few 
datapoints for the best performer, we decided to assume a normal 
distribution in calculating the upper limit value, which provides a 
more stringent limit, rather than a lognormal distribution. (See 2009 
memorandum entitled ``Revised MACT Floors, Data Variability Analysis, 
and Emission Limits for Existing and New HMIWI,'' which is included in 
the docket.) (A lognormal distribution would tend to provide less 
stringent emissions limits than a normal distribution.)
    We used the 99th percentile to calculate the upper limits, because 
we found it provided a more reasonable compensation for variability 
than the other percentiles we considered (i.e., 90, 95 and 99.9 
percent). We determined the emissions limits by rounding up the upper 
limit values to two significant figures, in accordance with standard 
engineering practices.

    Note: In the preamble to the October 6, 2009, final rule, we 
erroneously referred to these calculated values as ``upper 
confidence limits'' or ``UCLs.'' In today's notice, we are using the 
more accurate term ``upper limits.''

    The following two sections discuss the proposed amendments to the 
NOX and SO2 NSPS emissions limits for new large 
HMIWI, which have been revised to correspond to the aforementioned 
standard-setting process. The third section discusses the proposed 
amendments to the reporting and recordkeeping requirements for new 
HMIWI, which have been revised to correct the cross-reference to Sec.  
60.56c.

A. Nitrogen Oxides Emissions Limit

    For the large HMIWI size subcategory, the NOX emissions 
estimate associated with the best controlled similar unit is 66.9 parts 
per million by volume (ppmv). (See 2009 memorandum entitled ``Revised 
MACT Floors, Data Variability Analysis and Emission Limits for Existing 
and New HMIWI,'' which is included in the docket.) Because there were 
only a few datapoints for NOX for the best performer, we 
assumed a normal distribution in calculating the NOX upper 
limit value. The 99 percent upper limit for NOX for new 
large HMIWI (assuming a normal distribution) is 144 ppmv. (See 2009 
memorandum entitled ``Revised MACT Floors, Data Variability Analysis, 
and Emission Limits for Existing and New HMIWI,'' which is included in 
the docket.) Rounding up to two significant figures, we estimated the 
NOX emissions limit for new large HMIWI would be 150 ppmv, 
which would be less stringent than the corresponding NOX EG 
limit for existing HMIWI (140 ppmv).
    This unusual situation occurred due to a difference in the size of 
the datasets used to determine the NOX upper limit values 
for existing and new HMIWI. The NOX dataset for the best 
performer (used to determine the MACT floor for NOX for new 
sources) was smaller than the NOX dataset for the best-
performing 12 percent of sources (used to determine the MACT floor for 
existing sources) and had a higher standard deviation.

[[Page 27252]]

Since the upper limit calculation depends on both the average and 
standard deviation, the higher standard deviation resulted in the 
NOX upper limit value for the best performer being less 
stringent. (See 2009 memorandum entitled ``Revised MACT Floors, Data 
Variability Analysis, and Emission Limits for Existing and New HMIWI,'' 
which is included in the docket.)
    In this and other similar cases, we decided to use existing source 
limits for new sources where they are more stringent than new source 
limits, in order to prevent a situation where a new source would have a 
less stringent emissions limit than an existing source. We estimated 
the NOX EG limit for existing large HMIWI to be 140 ppmv. 
(See 2009 memorandum entitled ``Revised MACT Floors, Data Variability 
Analysis, and Emission Limits for Existing and New HMIWI,'' which is 
included in the docket.) Therefore, the NSPS NOX emissions 
limit for new large HMIWI should have also been 140 ppmv. However, a 
NOX NSPS limit of 130 ppmv was erroneously published, which 
does not correspond to our analytical process.
    The source of this error lies in the previous draft of the 
NOX EG limit for existing large HMIWI (130 ppmv), which was 
incorrectly determined assuming a normal distribution of the 
NOX emissions dataset for the best-performing 12 percent of 
the large HMIWI size subcategory. The distribution of the 
NOX emissions dataset for the best-performing 12 percent of 
large HMIWI was actually lognormal (based on a skewness of 1.44). 
Assuming a normal distribution would result in a NOX upper 
limit value of 121 ppmv, which would be rounded up to 130 ppmv to 
establish the NOX EG limit. Assuming a lognormal 
distribution, the NOX upper limit would actually be 131 
ppmv, which would be rounded up to 140 ppmv to establish the 
NOX EG limit. The correct NOX EG limit (140 ppmv) 
was included in the final rule for existing large HMIWI, but the 
incorrect, previous draft of the NOX NSPS limit (130 ppmv) 
was erroneously included in the final rule for new large HMIWI. Today's 
action proposes to correct this error and amend the HMIWI NSPS to 
include the correct NOX NSPS limit of 140 ppmv for new large 
HMIWI, which matches the final NOX EG limit and reflects 
EPA's intent in the October 6, 2009 final rule.

B. Sulfur Dioxide Emissions Limit

    For the large HMIWI size subcategory, the SO2 emissions 
estimate associated with the best controlled similar unit is 0.462 
ppmv. (See 2009 memorandum entitled ``Revised MACT Floors, Data 
Variability Analysis, and Emission Limits for Existing and New HMIWI,'' 
which is included in the docket.) In our analysis for the October 6, 
2009, final rule, we indicated that the SO2 data for the 
best performer were normally distributed, but a closer examination of 
the skewness of the data (0.54) indicates that the SO2 data 
are actually lognormally distributed. For the October 6, 2009, final 
rule, we erroneously estimated a 99 percent upper limit of 1.59 ppmv 
and an emissions limit of 1.6 ppmv for new large HMIWI, based on our 
incorrect estimation that the SO2 data were normally 
distributed. (See 2009 memorandum entitled ``Revised MACT Floors, Data 
Variability Analysis, and Emission Limits for Existing and New HMIWI,'' 
which is included in the docket.) The 99 percent upper limit for 
SO2 for new large HMIWI based on a lognormal distribution is 
8.04 ppmv. Rounding up to two significant figures, the SO2 
NSPS emissions limit should be 8.1 ppmv, if our standard-setting 
process is to be correctly followed. (See 2009 memorandum entitled 
``Revised Sulfur Dioxide MACT Floor, Data Variability Analysis, and 
Emission Limit for New Large HMIWI,'' which is included in the docket.) 
This action proposes to amend the HMIWI NSPS to include the correct 
SO2 limit of 8.1 ppmv for new large HMIWI, which reflects 
EPA's intent in the October 6, 2009, final rule.

C. Reporting and Recordkeeping Requirements

    The NSPS reporting and recordkeeping requirements of the October 6, 
2009, final rule include three separate cross-references to ``Sec.  
60.56(d), (h), or (j).'' The correct cross-reference in each case 
should have been ``Sec.  60.56c(d), (h), or (j),'' consistent with the 
section numbering format for NSPS subpart Ec. This action proposes to 
amend the HMIWI NSPS to correct this error.

IV. Impacts of the Proposed Action

    Based on the stringency of the HMIWI standards promulgated on 
October 6, 2009, sources would likely respond to the HMIWI rule by 
choosing not to construct new HMIWI and would use alternative waste 
disposal options rather than incur the costs of compliance. Considering 
this information, we do not anticipate any new HMIWI, and, therefore, 
no costs or impacts are associated with the proposed NSPS amendments 
for NOX and SO2 for new large units.
    However, in the unlikely event that a new unit is constructed, we 
estimated costs and impacts expected for each of three HMIWI model 
plants (large, medium and small), which we entered into the docket for 
the October 6, 2009, promulgation. (See 2009 memoranda entitled 
``Revised Compliance Costs and Economic Inputs for New HMIWI'' and 
``Revised Baseline Emissions and Emissions Reductions for Existing and 
New HMIWI,'' which are included in the docket.) We estimated baseline 
NOX emissions of 80 ppmv and baseline SO2 
emissions of 0.84 ppmv for the large HMIWI model plant, based on the 
average NOX and SO2 emissions measured at the 
latest large HMIWI to be installed since the 1997 rule. Consequently, 
the NOX and SO2 emissions associated with the 
large HMIWI model plant are already below both the incorrect 
NOX and SO2 emissions limits of 130 ppmv and 1.6 
ppmv, respectively, promulgated in the October 6, 2009, Federal 
Register notice and the correct NOX and SO2 
emissions limits of 140 ppmv and 8.1 ppmv, respectively, being proposed 
in today's action. Therefore, even if a new large unit were 
constructed, we would estimate no cost savings or negative impacts 
associated with today's proposed amendments to the NOX and 
SO2 emissions limits for new large HMIWI.

V. Statutory and Executive Order Reviews

A. Executive Order (EO) 12866: Regulatory Planning and Review

    This proposed action is not a ``significant regulatory action'' 
under the terms of EO 12866 (58 FR 51735, October 4, 1993) and is, 
therefore, not subject to review under the EO.

B. Paperwork Reduction Act

    This proposed action does not impose an information collection 
burden under the provisions of the Paperwork Reduction Act, 44 U.S.C. 
3501 et seq. Burden is defined at 5 CFR 1320.3(b). Today's proposed 
rule only includes revised NOX and SO2 emissions 
limits for new large HMIWI, and, as noted previously, no new HMIWI are 
anticipated. Consequently, today's proposed action will not impose any 
additional information collection burden for new sources.

C. Regulatory Flexibility Act

    The Regulatory Flexibility Act generally requires an agency to 
prepare a regulatory flexibility analysis of any rule subject to notice 
and comment rulemaking requirements under the Administrative Procedures 
Act or any other statute unless the agency certifies that the rule will 
not have a significant

[[Page 27253]]

economic impact on a substantial number of small entities. Small 
entities include small businesses, small organizations and small 
governmental jurisdictions.
    For purposes of assessing the impacts of this proposed action on 
small entities, small entity is defined as follows: (1) A small 
business as defined by the Small Business Administration's regulations 
at 13 CFR 121.201; (2) a small governmental jurisdiction that is a 
government of a city, county, town, school district or special district 
with a population of less than 50,000; or (3) a small organization that 
is any not-for-profit enterprise that is independently owned and 
operated and is not dominant in its field.
    After considering the economic impacts of this proposed rule on 
small entities, I certify that this proposed action will not have a 
significant economic impact on a substantial number of small entities. 
This proposed rule will not impose any requirements on small entities. 
Today's proposed action only includes revised NOX and 
SO2 emissions limits for new large HMIWI, and no new HMIWI 
are anticipated.

D. Unfunded Mandates Reform Act

    This action contains no Federal mandates under the provisions of 
Title II of the Unfunded Mandates Reform Act (UMRA), 2 U.S.C. 1531-1538 
for State, local or tribal governments or the private sector. This 
proposed action imposes no enforceable duty on any State, local or 
tribal governments or the private sector. Therefore, this proposed 
action is not subject to the requirements of sections 202 or 205 of the 
UMRA.
    This proposed action is also not subject to the requirements of 
section 203 of UMRA because it contains no regulatory requirements that 
might significantly or uniquely affect small governments.

E. Executive Order 13132: Federalism

    EO 13132 (64 FR 43255; August 10, 1999) requires EPA to develop an 
accountable process to ensure ``meaningful and timely input by State 
and local officials in the development of regulatory policies that have 
federalism implications.'' ``Policies that have federalism 
implications'' are defined in the EO to include regulations that 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.''
    This proposed rule 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, 
as specified in EO 13132. This proposed action will not impose 
substantial direct compliance costs on State or local governments, and 
will not preempt State law. Thus, EO 13132 does not apply to this rule.
    In the spirit of EO 13132 and consistent with EPA policy to promote 
communications between EPA and State and local governments, EPA 
specifically solicits comment on this proposed rule from State and 
local officials.

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

    This action does not have tribal implications, as specified in EO 
13175 (65 FR 67249; November 9, 2000). EPA is not aware of any HMIWI 
owned or operated by Indian tribal governments. Thus, EO 13175 does not 
apply to this action.
    EPA specifically solicits additional comment on this proposed 
action from tribal officials.

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

    EPA interprets EO 13045 (62 FR 19885; April 23, 1997) as applying 
to those regulatory actions that concern health or safety risks, such 
that the analysis required under section 5-501 of the Order has the 
potential to influence the regulation. This proposed action is not 
subject to EO 13045 because it is based solely on technology 
performance.

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

    This action is not a ``significant energy action'' as defined in EO 
13211 (66 FR 28355; May 22, 2001) because it is not likely to have a 
significant adverse effect on the supply, distribution or use of 
energy.

I. National Technology Transfer and Advancement Act

    Section 12(d) of the National Technology Transfer and Advancement 
Act of 1995 (``NTTAA''), Public Law No. 104-113, 12(d) (15 U.S.C. 272 
note) directs EPA to use voluntary consensus standards in its 
regulatory activities unless to do so would be inconsistent with 
applicable law or otherwise impractical. Voluntary consensus standards 
are technical standards (e.g., materials specifications, test methods, 
sampling procedures and business practices) that are developed or 
adopted by voluntary consensus standards bodies. NTTAA directs EPA to 
provide Congress, through the Office of Management and Budget, 
explanations when the Agency decides not to use available and 
applicable voluntary consensus standards.
    This proposed rulemaking does not involve technical standards. 
Therefore, EPA is not considering the use of any voluntary consensus 
standards.

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

    EO 12898 (59 FR 7629)(February 16, 1994) establishes Federal 
executive policy on environmental justice. Its main provision directs 
Federal agencies, to the greatest extent practicable and permitted by 
law, to make environmental justice part of their mission by identifying 
and addressing, as appropriate, disproportionately high and adverse 
human health or environmental effects of their programs, policies and 
activities on minority populations and low-income populations in the 
United States.
    EPA has determined that this proposed rule will not have 
disproportionately high and adverse human health or environmental 
effects on minority or low-income populations because it affects only 
new large units and no new units are anticipated to be constructed.
