RIN 2060-AO23
Standards of Performance for Stationary Combustion Turbines
AGENCY: Environmental Protection Agency (EPA).
ACTION: Direct final rule.
-----------------------------------------------------------------------
SUMMARY: EPA is taking direct final action on amendments to the sulfur
dioxide air emission standards for stationary combustion turbines that
burn biogas (landfill gas, digester gas, etc.). Without these
amendments, owners/operators of new stationary combustion turbines
burning biogas containing relatively low amounts of sulfur-containing
compounds will be required to install pretreatment facilities to remove
the sulfur compounds prior to combustion or to install post combustion
controls to lower sulfur dioxide emissions. It was not EPA's intent to
require the use of either of these approaches, and the costs associated
with either approach are substantially greater than the environmental
benefit resulting from the decrease in sulfur dioxide emissions.
DATES: This direct final rule is effective on May 19, 2009 without
further notice, unless EPA receives relevant adverse comment by April
20, 2009. If EPA receives relevant adverse comment, we will publish a
timely withdrawal in the Federal Register informing the public that the
amendments in this rule will not take effect.

K. Congressional Review Act
I. Why is EPA using a direct final rule?
We are publishing the rule without a prior proposed rule because we
view this as a non-controversial action and anticipate no adverse
comment. As explained below, this action amends the sulfur dioxide
emission limit for the stationary combustion turbine new source
performance standards, subpart KKKK of 40 CFR part 60, to account for
the lower heating value of biogas relative to distillate oil. Without
these amendments, the rule will require owners/operators of new
stationary combustion turbines burning biogas containing relatively low
concentrations of sulfur-containing compounds to either install
pretreatment facilities to remove the sulfur from the gas prior to
combustion or post combustion controls to lower sulfur dioxide
emissions. This requirement is problematic for a number of reasons.
First, we did not intend this outcome. Second, since the outcome was
not intended, it was not reflected in the proposed rule (70 FR 3814)
thereby depriving people of a meaningful opportunity to comment on the
requirement. Third, we have concluded that the costs associated with
either of these options are substantially greater than any
environmental benefit resulting from the decrease in sulfur dioxide
emissions.
If we receive relevant adverse comment on this direct final rule,
we will publish a timely withdrawal in the Federal Register informing
the public that the amendments in this rule will not take effect. Any
parties interested in commenting must do so at this time.
II. Does this action apply to me?

action will be posted on the TTN's policy and guidance page for newly
proposed or promulgated rules at the following address: http://www.epa.gov/ttn/oarpg/. The TTN provides information and technology
exchange in various areas of air pollution control.
IV. Why are we amending the rule?
The proposal for subpart KKKK (70 FR 8314) included a fuel-based
sulfur dioxide (SO2) limit of 500 parts per million by
weight (ppmw) sulfur. The rule, as adopted, (71 FR 38482) contains a
fuel-based SO2 limit of 0.060 pounds per million British
thermal units (lb/MMBtu). The adopted SO2 limit was based on
the potential SO2 emissions rate of natural gas containing
20 grains of sulfur per 100 standard cubic feet and 500 ppmw sulfur
distillate oil. The change from a fuel-based limit to a
[[Page 11860]]
potential SO2 emission rate was not intended to
substantially change the stringency of the standard. However, fuels
with low energy density, such as biogas, have a higher potential
SO2 emission rate relative to the sulfur concentration in
the fuel because of their lower heating value. As a result, this change
in format is causing difficulties for owners/operators of new
stationary combustion turbines planning to burn landfill gas. We did
not intend, in adopting the rule, to require biogas projects (landfill
gas, digester gas, etc.) burning fuel with less than 500 ppmw sulfur,
but having a potential SO2 emission rate of greater than
0.060 lb/MMBtu due to the low heating value of the gas, to install an
SO2 control device.
Much of the biogas generated in the United States has a potential
SO2 emissions rate of less than 0.060 lb/MMBtu; however,
this is not true in all cases. It was not our intent to require owners/
operators of biogas projects containing higher, but still moderate,
amounts of sulfur-containing compounds to install additional controls.
The control requirement was not supported by our impacts analysis or by
public comments received on the proposal. Furthermore, the costs
associated with installing and operating any such controls
substantially outweigh any environmental benefits resulting from lower
sulfur emissions.
Most of stationary combustion turbine projects burning biogas are
small sources of criteria pollutant emissions and produce less than 10
megawatts of power. Biogas projects that use moderate amounts of
sulfur-containing compounds would have less attractive economic returns
if required to achieve an emissions rate of 0.060 lb SO2/
MMBtu due to the substantial costs associated with installing and
operating the necessary controls and may be cancelled. Unless an
alternate use for biogas is found, it is often flared or directly
vented to the atmosphere. Stationary combustion turbines that burn
biogas have comparable emissions to landfill flares and have the added
benefit of using an opportunity fuel that would otherwise be wasted,
thereby reducing emissions. Accordingly, we are concerned that
requiring biogas burning units to comply with the 0.060 lb
SO2/MMBtu standard will result in a worse environmental
outcome and will waste energy resources and thus would not constitute
best demonstrated technology for such units.
V. What amendments are we making to the rule?
As currently written, Sec. 60.4330(a)(2) requires owners/operators
of stationary combustion turbines burning biogas containing more than
approximately 180 ppm hydrogen sulfide (H2S) to install SO2
controls, which was neither proposed nor intented. To remedy this, we
are establishing a new subcategory for owners/operators of stationary
combustion turbines burning over fifty percent biogas. The new
subcategory will have an SO2 limit of 0.15 lb/MMBtu (closer
to the original fuel-based 500 ppm sulfur limit) for new units, i.e.,
those for which construction, reconstruction, or modification is
commenced after the effective date of this rule, and units presently
subject to subpart KKKK. We are also adding a definition for biogas.
VI. Statutory and Executive Order Reviews
A. Executive Order 12866: Regulatory Planning and Review
This action is not a ``significant regulatory action'' under the
terms of Executive Order 12866 (58 FR 51735, October 4, 1993) and is,
therefore, not subject to review under the Executive Order.
B. Paperwork Reduction Act
This action does not impose any new information collection burden.
The proposed amendments result in no changes to the information
collection requirements of the existing standards of performance and
will have little or no impact on the information collection estimate of
projected cost and hour burden made and approved by the Office of
Management and Budget (OMB) during the development of the existing
standards of performance. Therefore, the information collection
requests have not been amended. However, OMB has previously approved
the information collection requirements contained in the existing
regulations (subpart KKKK, 40 CFR part 60) under the provisions of the
Paperwork Reduction Act, 44 U.S.C. 3501 et seq., and has assigned OMB
control number 2060-0582 (ICR 2177.02). The OMB control numbers for
EPA's regulations in 40 CFR are listed in 40 CFR part 9.
C. Regulatory Flexibility Act
The Regulatory Flexibility Act (RFA) generally requires an agency
to prepare a regulatory flexibility analysis of any rule subject to
notice and comment rulemaking requirements under the Administrative
Procedure Act or any other statute unless the agency certifies that the
rule will not have a significant 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 the proposed amendments on
small entities, small entity is defined as: (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; and (3) a small organization that is
any not-for-profit enterprise which is independently owned and operated
and is not dominant in its field.
After considering the economic impacts of this direct final rule on
small entities, I certify that this action will not have a significant
economic impact on a substantial number of small entities. In
determining whether a rule has a significant economic impact on a
substantial number of small entities, the impact of concern is any
significant adverse economic impact on small entities, since the
primary purpose of the regulatory flexibility analyses is to identify
and address regulatory alternatives ``which minimize any significant
economic impact of the rule on small entities.'' 5 U.S.C. 603 and 604.
Thus, 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, or otherwise has a positive economic effect
on all of the small entities subject to the rule.
Although this direct final rule will not have a significant
economic impact on a substantial number of small entities, EPA
nonetheless has tried to reduce the impact of this rule on small
entities. If adopted, the amended sulfur dioxide limit for owners and
operators of turbines burning biogas will reduce the compliance burden
of the rule.
Therefore, EPA has concluded that this direct final rule will
relieve regulatory burden for all affected small entities.
D. Unfunded Mandates Reform Act
This direct final rule reduces burden and does not contain 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 1 year. Thus, this direct final rule is not
subject to the requirements of sections 202 and 205 of UMRA.
This direct final rule 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. If adopted,
the amended
[[Page 11861]]
sulfur dioxide limit for owners and operators of turbines burning
biogas will reduce the regulatory burden for small governments that own
or operate stationary combustion turbines burning biogas.
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'' is 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 direct final 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 direct final
rule will not impose substantial direct compliance costs on State or
local governments; it will not preempt State law. Thus, Executive Order
13132 does not apply to this rule.
F. Executive Order 13175: Consultation and Coordination With Indian
Tribal Governments
This action does not have tribal implications, as specified in
Executive Order 13175 (65 FR 67249, November 9, 2000). EPA is not aware
of any stationary combustion turbine owned by an Indian tribe. In the
event that an Indian tribe does own a stationary combustion turbine
burning biogas, the amendments will benefit the tribe to the same
extent as any other owner/operator. Thus, Executive Order 13175 does
not apply to this action.
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 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
action is not subject to Executive Order 13045 because it is based
solely on technology performance.
H. Executive Order 13211: Actions Concerning Regulations That
Significantly Affect Energy Supply, Distribution, or Use
This action is not subject to Executive Order 13211, (66 FR 28355,
May 22, 2001) because it is not a significant regulatory action under
Executive Order 12866.
I. National Technology Transfer 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 (VCS) 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 VCS bodies. The NTTAA directs EPA to provide Congress,
through OMB, explanations when the Agency does not use available and
applicable VCS.
These direct final rule amendments do not involve technical
standards as defined in the NTTAA. Therefore, this direct final rule is
not subject to NTTAA.
J. Executive Order 12898: Federal Actions To Address Environmental
Justice in Minority Populations and Low-Income Populations.
Executive Order 12898 (59 FR 7629, February 16, 1994) establishes
Federal executive policy on environmental justice. Its main provision
directs Federal agencies, to the greatest extent practical 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 direct final rule will not have
disproportionately high 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. In the absence of the proposed amendments, the biogas would
likely either be flared or combusted in reciprocating internal
combustion engines. Emissions from either of these options would be
similar or higher than the proposed amended limits for stationary
combustion turbines burning biogas.
K. Congressional Review Act
The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the
Small Business Regulatory Enforcement Fairness Act of 1996, 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
United States. EPA will submit a report containing this rule and other
required information to the U.S. Senate, the U.S. House of
Representatives, and the Comptroller General of the United States prior
to publication of the direct final rule in the Federal Register. The
direct final rule is not a ``major rule'' as defined by 5 U.S.C.
804(2). The direct final rule is effective May 19, 2009.
