codes, the most conservative SBA definition (i.e., the NAICS code with
the highest employee or revenue size standard) was used.
    As mentioned earlier in this preamble, facilities across several
industries use affected RICE, so therefore a number of size standards
are utilized in this analysis. For the 9 industries identified at the
6-digit NAICS code represented in this analysis, the employment size
standard varies from 500 to 1,000 employees. The annual sales standard
is as low as 0.75 million dollars and as high as 34 million dollars. In
addition, for the electric power generation industry, the small
business size standard is an ultimate parent entity defined as having a
total electric output of 4 million megawatt-hours (MW-hr) in the
previous fiscal year. The specific SBA size standard is identified for
each affected industry within the industry profile to support this
economic analysis.
    After considering the economic impacts of this final rule on small
entities, we have concluded that this action will not have a
significant economic impact on a substantial number of small entities
(or SISNOSE). This certification is based on the economic impact of
this proposed action to all affected small entities across all
industries affected. We estimate that all small entities will have
annualized costs of less than 1 percent of their sales in all
industries except NAICS 2211 (electric power generation, transmission,
and distribution). In this case, however, the number of small entities
having annualized costs of greater than 1 percent of their sales is
less than 10 percent. Hence, we conclude that there is no SISNOSE for
this proposal.
    Although the proposed rule will not have a significant economic
impact on a substantial number of small entities, we nonetheless tried
to reduce the impact of the proposed rule on small entities. We held
meetings with industry trade associations and company representatives
to discuss the proposed rule and included provisions to limit
monitoring and recordkeeping requirements to the extent possible. We
continue to be interested in the potential impacts of the proposed
action on small entities and welcome comments on issues related to such
impacts.

D. Unfunded Mandates Reform Act of 1995

    Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), 2
U.S.C. 1531-1538, requires Federal agencies, unless otherwise
prohibited by law, to assess the effects of their regulatory actions on
State, local, and tribal governments and the private sector. This rule
contains a Federal mandate that may result in expenditures of $100
million or more for State, local, and tribal governments, in the
aggregate, or the private sector in any one year. Accordingly, EPA has
prepared under section 202 of the UMRA a written statement which is
summarized below.
    As discussed previously in this preamble, the statutory authority
for the proposed rule is section 112 of the CAA. Section 112(b) lists
the 189 chemicals, compounds, or groups of chemicals deemed by Congress
to be HAP. These toxic air pollutants are to be regulated by NESHAP.
Section 112(d) of the CAA directs us to develop NESHAP based on MACT,
which require existing and new major sources to control emissions of
HAP. EPA is required to address HAP emissions from stationary RICE
located at area sources under section 112(k) of the CAA, based on
criteria set forth by EPA in the Urban Air Toxics Strategy previously
discussed in this preamble. These NESHAP apply to existing stationary
RICE less than or equal to 500 HP located at major sources of HAP
emissions, existing non-emergency stationary CI RICE greater than 300
HP, and existing stationary RICE located at area sources of HAP
emissions.
    In compliance with section 205(a), we identified and considered a
reasonable number of regulatory alternatives. The regulatory
alternative upon which the rule is based is the least costly, most
cost-effective alternative to achieve the statutory requirements of
Clean Air Act section 112.
1. Social Costs and Benefits
    The RIA prepared for the proposed rule, including the Agency's
assessment of costs and benefits, is detailed in the ``Regulatory
Impact Analysis for the Proposed RICE NESHAP'' in the docket. Based on
estimated compliance costs on all sources associated with the proposed
rule and the predicted change in prices and production in the affected
industries, the estimated social costs of the proposed rule are $345
million (2007 dollars). It is estimated that by 2013, HAP will be
reduced by 13,000 tpy due to reductions in formaldehyde, acetaldehyde,
acrolein, methanol and other HAP from existing stationary RICE.
Formaldehyde and acetaldehyde have been classified as ``probable human
carcinogens.'' Acrolein, methanol and the other HAP are not considered
carcinogenic, but produce several other toxic effects. The proposed
rule will also achieve reductions in 511,000 tons of CO, approximately
79,000 tons of NOX per year, about 90,000 tons of VOC per
year, and approximately 2,600 tons of PM per year, in the year 2013.
Exposure to CO can affect the cardiovascular system and the central
nervous system. Emissions of NOX can transform into PM,
which can result in fatalities and many respiratory problems (such as
asthma or bronchitis); and NOX can also transform into ozone
causing several respiratory problems to affected populations.
    The total monetized benefits of the proposed rule range from $0.9
to $2.0 billion. (2007 dollars).
2. Future and Disproportionate Costs
    The UMRA requires that we estimate, where accurate estimation is
reasonably feasible, future compliance costs imposed by the rule and
any disproportionate budgetary effects. Our

estimates of the future compliance costs of the proposed rule are
discussed previously in this preamble. We do not believe that there
will be any disproportionate budgetary effects of the proposed rule on
any particular areas of the country, State or local governments, types
of communities (e.g., urban, rural), or particular industry segments.
3. Effects on the National Economy
    The UMRA requires that we estimate the effect of the proposed rule
on the national economy. To the extent feasible, we must estimate the
effect on productivity, economic growth, full employment, creation of
productive jobs, and international competitiveness of the U.S. goods
and services if we determine that accurate estimates are reasonably
feasible and that such effect is relevant and material. The nationwide
economic impact of the proposed rule is presented in the ``Regulatory
Impact Analysis for RICE NESHAP'' in the docket. This analysis provides
estimates of the effect of the proposed rule on most of the categories
mentioned above. The results of the economic impact analysis were
summarized previously in this preamble. In addition, we have determined
that the proposed rule contains no regulatory requirements that might
significantly or uniquely affect small governments. Therefore, this
rule is not subject to the requirements of section 203 of the UMRA.

E. Executive Order 13132: Federalism

    Executive Order 13132, entitled ``Federalism'' (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
Executive Order 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 Executive Order 13132. This proposed rule primarily
affects private industry, and does not impose significant economic
costs on State or local governments. Thus, Executive Order 13132 does
not apply to this proposed rule.
    In the spirit of Executive Order 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 proposed rule does not have tribal implications as specified
in Executive Order 13175 (65 FR 67249, November 9, 2000). It will not
have substantial direct effects on tribal governments, on the
relationship between the Federal government and Indian tribes, or on
the distribution of power and responsibilities between the Federal
government and Indian tribes, as specified in Executive Order 13175.
Thus, Executive Order 13175 does not apply to this proposed rule.

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

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

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

    This action is not a ``significant energy action'' as defined in
Executive Order 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. EPA has prepared an analysis of energy
impacts that explains this conclusion as follows below.
    With respect to energy supply and prices, EPA's analysis suggests
that at the industry level, the annualized costs represent a very small
fraction of revenue (less than 0.7 percent). As a result, EPA can
conclude supply and price impacts on affected energy producers and
consumers should be small.
    To enhance understanding regarding the regulation's influence on
energy consumption, EPA examined publicly available data describing
energy consumption for the electric power sector. The electric power
sector is expected to incur more than 40 percent of the $345 million in
compliance costs associated with the proposed rule, and the industry is
expected to incur the greatest share of the costs relative to other
affected industries. The Annual Energy Outlook 2009 (EIA, 2008)
provides energy consumption data. Since this rule only affects diesel
and natural gas-fired RICE, EPA's analysis focuses on impacts of
consumption of these fuels. As shown in Table 6 of this preamble, the
electric power sector accounts for less than 0.5 percent of the U.S.
total liquid fuels (which includes diesel fuel) and less than 6.5
percent of U.S. natural gas consumption. As a result, any energy
consumption changes attributable to the proposed rule should not
significantly influence the supply, distribution, or use of energy
nationwide.

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 OMB, 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.
    Under Sec.  63.7(f) and Sec.  63.8(f) of subpart A of the General
Provisions, a source may apply to EPA for permission to use alternative
test methods or alternative monitoring requirements in place of any
required or referenced testing methods, performance specifications, or
procedures.

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

    Executive Order 12898 (59 FR 7629 (Feb. 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 increases the
level of environmental protection for all affected populations without
having any disproportionately high and adverse human health or
environmental effects on any population, including any minority or low-
income population. This proposed rule is expected to reduce HAP
emissions from stationary RICE and thus decrease the amount of such
emissions to which all affected populations are exposed.

* * * * *
    13. Section 63.6625 is amended by adding paragraphs (e), (f) and
(g) to read as follows:

Sec.  63.6625   What are my monitoring, installation, operation, and
maintenance requirements?

* * * * *
    (e) If you own or operate an existing stationary RICE with a site
rating of less than 100 brake HP located at a major source of HAP
emissions, an existing stationary emergency RICE, or an existing
stationary RICE located at an area source of HAP emissions not subject
to any numerical emission standards shown in Table 2d to this subpart,
you must operate and maintain the stationary RICE and aftertreatment
control device (if any) according to the manufacturer's emission-
related written instructions or develop your own maintenance plan which
must provide to the extent practicable for the maintenance and
operation of the engine in a manner consistent with good

air pollution control practice for minimizing emissions.
    (f) If you own or operate an existing emergency stationary RICE
with a site rating of less than or equal to 500 brake HP located at a
major source of HAP emissions or an existing emergency stationary RICE
located at an area source of HAP emissions, you must install a non-
resettable hour meter if one is not already installed.

site rating of less than or equal to 500 brake HP located at a major
source of HAP emissions or an existing stationary 4SRB RICE located at
an area source of HAP emissions, air-to-fuel ratio controllers (AFRC)
are required to be used with the operation of three-way catalysts/non-
selective catalytic reduction. The AFRC must be maintained and operated
appropriately in order to ensure proper operation of the engine and
control device to minimize emissions at all times.
    14. Section 63.6640 is amended as follows:
    a. By revising paragraph (a);
    b. By revising paragraph (b);
    c. By revising paragraph (e); and
    d. By adding paragraph (f).

Sec.  63.6640   How do I demonstrate continuous compliance with the
emission limitations and operating limitations?

    (a) You must demonstrate continuous compliance with each emission
limitation and operating limitation in Tables 1a and 1b, Tables 2a and
2b, Table 2c, and Table 2d to this subpart that apply to you according
to methods specified in Table 6 to this subpart.
    (b) You must report each instance in which you did not meet each
emission limitation or operating limitation in Tables 1a and 1b, Tables
2a and 2b, Table 2c, and Table 2d to this subpart that apply to you.
These instances are deviations from the emission and operating
limitations in this subpart. These deviations must be reported
according to the requirements in Sec.  63.6650. If you change your
catalyst, you must reestablish the values of the operating parameters
measured during the initial performance test. When you reestablish the
values of your operating parameters, you must also conduct a
performance test to demonstrate that you are meeting the required
emission limitation applicable to your stationary RICE.
* * * * *
    (e) You must also report each instance in which you did not meet
the requirements in Table 8 to this subpart that apply to you. If you
own or operate a new or reconstructed stationary RICE with a site
rating of less than or equal to 500 brake HP located at a major source
of HAP emissions (except new or reconstructed 4SLB engines greater than
or equal to 250 and less than or equal to 500 brake HP), a new or
reconstructed stationary RICE located at an area source of HAP
emissions, or any of the following RICE with a site rating of more than
500 brake HP located at a major source of HAP emissions, you do not
need to comply with the requirements in Table 8 to this subpart: An
existing 2SLB stationary RICE, an existing 4SLB stationary RICE, an
existing emergency stationary RICE, an existing limited use emergency
stationary RICE, or an existing stationary RICE which fires landfill
gas or digester gas equivalent to 10 percent or more of the gross heat
input on an annual basis. If you own or operate any of the following
RICE with a site rating of more than 500 brake HP located at a major
source of HAP emissions, you do not need to comply with the
requirements in Table 8 to this subpart, except for the initial
notification requirements: a new or reconstructed stationary RICE that
combusts landfill gas or digester gas equivalent to 10 percent or more
of the gross heat input on an annual basis, a new or reconstructed
emergency stationary RICE, or a new or reconstructed limited use
stationary RICE.
    (f) If you own or operate an existing emergency stationary RICE
with a site rating of less than or equal to 500 brake HP located at a
major source of HAP emissions or an existing emergency stationary RICE
located at an area source of HAP emissions, you may operate your
emergency stationary RICE for the purpose of maintenance checks and
readiness testing, provided that the tests are recommended by Federal,
State or local government, the manufacturer, the vendor, or the
insurance company associated with the engine. Maintenance checks and
readiness testing of such units is limited to 100 hours per year. There
is no time limit on the use of emergency stationary ICE in emergency
situations. The owner or operator may petition the Administrator for
approval of additional hours to be used for maintenance checks and
readiness testing, but a petition is not required if the owner or
operator maintains records indicating that Federal, State, or local
standards require maintenance and testing of emergency RICE beyond 100
hours per year. Emergency stationary RICE may operate up to 50 hours
per year in non-emergency situations, but those 50 hours are counted
towards the 100 hours per year provided for maintenance and testing.
The 50 hours per year for non-emergency situations cannot be used for
peak shaving or to generate income for a facility to supply power to an
electric grid or otherwise supply power as part of a financial
arrangement with another entity. For owners and operators of emergency
engines, any operation other than emergency operation, maintenance and
testing, and operation in non-emergency situations for 50 hours per
year, as permitted in this section, is prohibited.
