Standards of Performance for Stationary Compression Ignition and 
Spark Ignition Internal Combustion Engines

AGENCY: The Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: The EPA is finalizing revisions to the standards of 
performance for new stationary compression ignition internal combustion 
engines under section 111(b) of the Clean Air Act. The final rule 
requires more stringent standards for stationary compression ignition 
engines with displacement greater than or equal to 10 liters per 
cylinder and less than 30 liters per cylinder, consistent with recent 
revisions to standards for similar mobile source marine engines. In 
addition, the action revises the requirements for engines with 
displacement at or above 30 liters per cylinder to align more closely 
with recent standards for similar mobile source marine engines, and for 
engines in remote portions of Alaska that are not accessible by the 
Federal Aid Highway System. The action also provides additional 
flexibility to owners and operators of affected engines, and corrects 
minor mistakes in the original standards of performance. Finally, the 
action makes minor revisions to the standards of performance for new 
stationary spark ignition internal combustion engines to correct minor 
errors and to mirror certain revisions finalized for compression 
ignition engines, which provides consistency where appropriate for the 
regulation of stationary internal combustion engines. The final 
standards will reduce nitrogen oxides by an estimated 1,100 tons per 
year, particulate matter by an estimated 38 tons per year, and 
hydrocarbons by an estimated 18 tons per year in the year 2030.

DATES: This final rule is effective on August 29, 2011.

C. Judicial Review

    Under section 307(b)(1) of the Clean Air Act (CAA), judicial review 
of this final rule is available only by filing a petition for review in 
the U.S. Court of Appeals for the District of Columbia Circuit by 
August 29, 2011. Under section 307(d)(7)(B) of the CAA, only an 
objection to this final rule that was raised with reasonable 
specificity during the period for public comment can be raised during 
judicial review. Moreover, under section 307(b)(2) of the CAA, the 
requirements established by this final rule may not be challenged 
separately in any civil or criminal proceedings brought by the EPA to 
enforce these requirements.
    Section 307(d)(7)(B) of the CAA further provides that ``[o]nly an 
objection to a rule or procedure which was raised with reasonable 
specificity during the period for public comment (including any public 
hearing) may be raised during judicial review.'' This section also 
provides a mechanism for the EPA to convene a proceeding for 
reconsideration, ``[i]f the person raising an objection can demonstrate 
to the EPA that it was impracticable to raise such objection within 
[the period for public comment] or if the grounds for such objection 
arose after the period for public comment (but within the time 
specified for judicial review) and if such objection is of central 
relevance to the outcome of the rule.'' Any person seeking to make such 
a demonstration to us should submit a Petition for Reconsideration to 
the Office of the Administrator, U.S. EPA, Room 3000, Ariel Rios 
Building, 1200 Pennsylvania Ave., NW., Washington, DC 20460, with a 
copy to both the person(s) listed in the preceding FOR FURTHER 
INFORMATION CONTACT section, and the Associate General Counsel for the 
Air and Radiation Law Office, Office of General Counsel (Mail Code 
2344A), U.S. EPA, 1200 Pennsylvania Ave., NW., Washington, DC 20460.

II. Background

    This action promulgates revisions to the new source performance 
standards (NSPS) for new compression ignition (CI) stationary internal 
combustion engines (ICE). The NSPS were originally promulgated on July 
11, 2006 (71 FR 39153). New source performance standards implement 
section 111(b) of the CAA, and are issued for categories of sources 
which cause, or contribute significantly to, air pollution which may 
reasonably be anticipated to endanger public health or welfare. The 
standards apply to new stationary sources of emissions, i.e., sources 
whose construction, reconstruction, or modification begins after a 
standard for those sources is proposed.
    For the first time, the NSPS put Federal restrictions on emissions 
of particulate matter (PM), oxides of nitrogen (NOX), non-
methane hydrocarbons (NMHC) and carbon monoxide (CO) from new 
stationary CI engines. The NSPS also restricted the level of sulfur 
permitted in diesel fuel used in new stationary CI engines. The levels 
in the NSPS were generally based on standards promulgated in previous 
rules for similar nonroad (i.e., mobile off-highway) engines. For 
larger engines with displacement greater than or equal to 10 liters per 
cylinder (l/cyl) and less than 30 l/cyl, the levels were based on 
standards for similar marine engines. For engines with displacement 
greater than or equal to 30 l/cyl, the standards were based on evidence 
collected for those specified engines.
    Following promulgation of the initial NSPS, the EPA received 
several comments from interested parties regarding aspects of the final 
rule. In particular, the Engine Manufacturers Association (EMA) stated 
its belief that the standards promulgated for engines with displacement 
greater than or equal to 30 l/cyl were not feasible, especially for 
those engines located in areas without requirements for low sulfur 
diesel fuel. Engine manufacturers also noted some minor errors in the 
standards as published. The American Petroleum Institute (API) 
petitioned for review of the final NSPS, and stated to the EPA that, 
among other concerns, API believed that the compliance requirements did 
not allow owner and operators enough flexibility to use operation and 
maintenance procedures that were different from those recommended by 
manufacturers, yet would still provide good emission control practice 
for minimizing emissions. API also had other comments regarding the 
final rule, including concerns regarding use of the term ``useful 
life'' in the stationary engine context, and concerns that temporary 
portable engines would be treated as subject to NSPS requirements 
beyond the requirements for nonroad engines. These amendments address 
the comments received from EMA and API.
    Additionally, on June 30, 2008, the EPA published more stringent 
standards for new locomotives and for new CI marine vessels under 40 
CFR parts 1033 and 1042, respectively, including marine vessel engines 
with displacement greater than or equal to 10 l/cyl and less than 30 l/
cyl (73 FR 37095). The rule promulgated two new tiers of standards for 
newly manufactured marine CI engines at or above 600 kilowatt (KW) (800 
horsepower (HP)), the second of which was based on the application of 
catalytic aftertreatment technology. Further, on April 30, 2010, the 
EPA promulgated final fuel requirements and standards regulating 
emissions from marine

[[Page 37956]]

engines with displacement above 30 l/cyl (75 FR 22896). These 
requirements are equivalent to the limits adopted by the International 
Maritime Organization (IMO) in October 2008 as an amendment to Annex VI 
of the International Convention for the Prevention of Pollution from 
Ships (also called MARPOL Annex VI). The EPA is revising the NSPS for 
stationary CI engines with a displacement greater than or equal to 10 
l/cyl to align them with the standards for similar marine engines.
    Also, on October 31, 2008, the State of Alaska, pursuant to the 
provision in the final NSPS for CI engines allowing it to request 
alternative provisions for remote Alaska, requested that the EPA make 
certain changes in its requirements to account for circumstances in 
remote Alaska that are different from those in the rest of the United 
States. These amendments revise the NSPS for stationary CI engines to 
address issues raised by the State of Alaska in its request.
    On January 18, 2008, the EPA published a final rule containing 
separate standards of performance for stationary spark ignition (SI) 
engines (73 FR 3567). While these regulations are distinct from the 
standards of performance for CI engines, certain aspects of these 
regulations, particularly regarding compliance and definitions, are 
intended to be consistent with the regulations promulgated for CI 
engines. Therefore, the EPA is making minor revisions to the NSPS for 
stationary SI engines to maintain consistency with the NSPS for 
stationary CI engines. In addition, the EPA received comments 
indicating minor errors in the regulations for SI engines. While the 
EPA is not making any significant changes to the SI regulations in this 
rule, except for those to maintain consistency, the EPA is correcting 
certain minor errors in the NSPS for stationary SI engines in this 
rule.

III. Summary of the Final Amendments

A. Standards for New Engines With Displacement Greater Than or Equal to 
10 l/cyl and Less Than 30 l/cyl

    The EPA is incorporating the standards for new marine engines that 
were promulgated on June 30, 2008 (73 FR 37095), into the NSPS for new 
stationary CI ICE with displacement greater than or equal to 10 l/cyl 
and less than 30 l/cyl. The standards were found to be feasible for the 
marine engines covered by those requirements. As discussed in the 
original NSPS final rule, stationary engines in this displacement range 
are similar in design to marine CI engines and are generally certified 
to marine standards. The EPA is, therefore, basing the standards for 
non-emergency stationary CI ICE with a displacement between 10 l/cyl 
and 30 l/cyl on the technologies identified in the June 30, 2008, 
rulemaking that are expected to be used to meet the emission standards 
for marine CI engines.
    The final standards would not take effect until 2013, at the 
earliest. The standards are summarized in Tables 1 and 2 in this 
preamble.

[[Page 37957]]


\c\ Interim Tier 4 PM standards for 2014 and 2015 model year engines with a displacement at or above 15 liters
  per cylinder are 0.25 g/HP-hr (0.34 g/KW-hr) for engines 2,000<=KW<3,300 and 0.20 g/HP-hr (0.27 g/KW-hr) for
  engines 3,300<=KW<3,700.

    The first tier of standards is based on engine-based technologies 
already in use or expected to be used for other mobile and stationary 
engines (e.g., improved fuel injection, engine mapping, and calibration 
optimization), as well as the use of ultra low sulfur (i.e., 15 parts 
per million (ppm) sulfur) diesel (ULSD). The second tier of standards 
is expected to be met with the use of catalytic exhaust aftertreatment 
that has already been used for other similar mobile and stationary 
engines, like catalyzed diesel particulate filters (CDPF) and selective 
catalytic reduction (SCR).

B. Standards for Engines With Displacement Greater Than or Equal to 30 
l/cyl

    In the initial final NSPS, the EPA required owners and operators of 
stationary CI ICE with a displacement of greater than or equal to 30 l/
cyl to reduce NOX emissions by 90 percent or more, or 
alternatively they had to limit the emissions of NOX in the 
stationary CI internal combustion engine exhaust to 1.6 grams per KW-
hour (g/KW-hr) (1.2 grams per HP-hour (g/HP-hr)). Owners and operators 
were also required to reduce PM emissions by 60 percent or more, or 
alternatively they had to limit the emissions of PM in the stationary 
CI internal combustion engine exhaust to 0.15 g/KW-hr (0.11 g/HP-hr). 
These standards were applicable in all areas, including areas in the 
Pacific (e.g., Guam) and remote areas of Alaska that were exempted, at 
least temporarily, from using low sulfur fuel. The standards were also 
applicable to all engines in this displacement category, whether they 
were used for emergency or non-emergency purposes.
    Following completion of the original rule, the EPA received 
comments from engine manufacturers stating that the standards would be 
infeasible in areas where low sulfur fuel was not used. The engine 
manufacturers recommended less stringent standards for areas where low 
sulfur fuel is not required. The EPA also received later comments 
indicating that the standards were also infeasible for engines in areas 
with access to lower sulfur fuel, and that the standards should instead 
be harmonized with the IMO standards for similar engines in marine 
vessels. These comments also requested that the EPA take the same 
approach to emergency engines with displacement greater than or equal 
to 30 l/cyl as the EPA takes for smaller emergency engines. For other 
emergency engines, the EPA promulgated emission standards that do not 
require the use of aftertreatment, given the limited use of the 
engines, the ineffectiveness of the aftertreatment during startup, and 
the need for safe, reliable and immediate operation of the engine 
during emergencies. The comments stated that engines of this size have 
been used as emergency generators at nuclear power plants in order to 
assure the safe shut-down of the reactor in case of emergency due to 
their excellent performance and reliability.
    Regarding the NOX standard for these engines, the EPA 
agrees that it is appropriate to adjust the stringency of the 
NOX standard to match the worldwide NOX standard 
approved in the IMO's Annex VI and promulgated by the EPA on April 30, 
2010 (75 FR 22896), for marine engines with displacement at or above 30 
l/cyl. While the technology required by the existing NSPS has been used 
on other stationary engines, the EPA realizes the need to provide lead 
time for the technology to transfer to the largest of engines. The 
final IMO NOX standard is comparable to the existing NSPS 
NOX standard, but provides more lead time for final 
implementation. Revising the standard to match the standard for marine 
engines allows manufacturers to design a single type of engine for both 
uses. This standard has been substantially reviewed by the EPA and 
other governments and has been found to be feasible in the time 
provided. For engines installed prior to January 1, 2012, the standard 
is 17.0 g/KW-hr (12.7 g/HP-hr) when maximum engine speed is less than 
130 revolutions per minute (rpm); 45 [middot] n-\0.2\ g/KW-
hr (34 [middot] n-\0.2\ g/HP-hr) when n (maximum engine 
speed) is 130 or more, but less than 2,000 rpm; 9.8 g/KW-hr (7.3 g/HP-
hr) when maximum engine speed is 2,000 rpm or more. For engines 
installed after January 1, 2012, the EPA is finalizing a more stringent 
standard of 14.4 g/KW-hr (10.7 g/HP-hr) when maximum engine speed is 
less than 130 rpm; 44 [middot] n-\0.23\ g/KW-hr (33 [middot] 
n-\0.23\ g/HP-hr) where n (maximum engine speed) is 130 or 
more but less than 2,000 rpm; and 7.7 g/KW-hr (5.7 g/HP-hr) where 
maximum engine speed is greater than or equal to 2,000 rpm. For engines 
installed after January 1, 2016, the EPA is finalizing a more stringent 
standard that presumes the use of aftertreatment. The levels are 3.4 g/
KW-hr (2.5 g/HP-hr) when maximum engine speed is less than 130 rpm; 9.0 
[middot] n-\0.20\ g/KW-hr (6.7 [middot] n-\0.20\ 
g/HP-hr) where n (maximum engine speed) is 130 or more but less than 
2,000 rpm; and 2.0 g/KW-hr (1.5 g/HP-hr) where maximum engine speed is 
greater than or equal to 2,000 rpm.
    For engines installed in Pacific island areas that are not required 
to use lower sulfur fuel, while the EPA believes that SCR can be 
installed on such engines even where high sulfur fuel is being used, 
the EPA agrees that the use of high sulfur fuel, and the presence of 
other impurities in this type of fuel (i.e., heavy fuel oil), as well 
as different density and viscosity, make it difficult to achieve 
similar results from SCR as would occur with lower sulfur fuel. 
Maintenance of high NOX reduction levels is also more 
difficult when using high sulfur fuel. The use of higher sulfur heavy 
fuel oil also increases engine-out NOX emissions because of 
the increased levels of contaminants in the fuel. The EPA also notes 
that the areas in question do not have any significant ozone problem. 
The EPA, therefore, is not requiring the more stringent standards that 
would otherwise apply beginning in 2016 in these areas.
    Similarly, the EPA is not requiring the more stringent, 
aftertreatment-forcing NOX standards for emergency engines 
with displacement at or above 30 l/cyl. As the commenters noted, the 
EPA did not require aftertreatment-forcing requirements for other 
emergency engines due to the limited use of the engines, the 
ineffectiveness of the aftertreatment during startup, and the need for 
safe, reliable and immediate operation of the engine during 
emergencies. The EPA agrees that similar concerns are present for 
emergency engines in this power category.
    The EPA is also modifying its fuel requirements for engines with 
displacement at or above 30 l/cyl. The final rule promulgated by the 
EPA for marine engines with displacement above 30 l/cyl required those 
engines to use fuel meeting a 1,000 ppm sulfur level beginning in 2014, 
and also made other revisions to the mobile source fuel requirements 
that will likely have the effect of making 1,000 ppm sulfur fuel the 
outlet for diesel fuel that does not meet the 15 ppm sulfur standard 
generally required for mobile source fuel. The EPA is revising the fuel 
sulfur standards for stationary CI engines with displacement at or 
above 30 l/cyl to a 1,000 ppm sulfur level beginning on June 1, 2012.

[[Page 37958]]

    The EPA agrees that the numerical standards for PM promulgated in 
the original final rule would be very difficult, if not impossible, to 
achieve using high sulfur fuel. The EPA therefore agrees that it is 
appropriate to revise the concentration limit for PM for stationary CI 
ICE with a displacement of greater than or equal to 30 l/cyl in areas 
where low sulfur fuel is not required. The EPA is finalizing a standard 
of 0.40 g/KW-hr (0.30 g/HP-hr). Given the substantial health concerns 
associated with diesel PM emissions, the EPA believes it is appropriate 
to require this level for all engines where low sulfur fuel is not 
required. Similarly, the EPA is revising the PM standard for emergency 
engines to 0.40 g/kW-hr (0.30 g/HP-hr), for the reasons provided above 
regarding NOX standards for such engines.
    The EPA is not changing the PM standard for non-emergency engines 
in areas where the lower sulfur fuel is available. As the EPA explained 
in the original NSPS, the EPA believes this standard is achievable for 
engines using existing technology and low sulfur fuel. The substantial 
health risks associated with diesel PM require that these stringent 
standards remain in place.

C. Compliance Requirements for Owners and Operators

    In the original final NSPS for stationary CI ICE, the EPA required 
all engines to be installed, configured, operated, and maintained 
according to the specifications and instructions provided by the engine 
manufacturer. The EPA also allowed the option for owners and operators 
to follow procedures developed by the owner or operator that have been 
approved by the engine manufacturer for cases where site-specific 
conditions may require changes to the manufacturer's typical 
guidelines.
    Several parties objected to this requirement. According to the 
parties, this requirement restricts owners and operators from using the 
most appropriate methods for installing, operating and maintaining 
engines in the field. The parties claim that owners and operators are 
in the best position to determine the most appropriate method of 
installing, operating and maintaining engines in the field and have 
more experience in doing so than engine manufacturers, and that 
operation and maintenance provisions in manufacturer manuals are often 
too stringent and inflexible to be required in binding regulations.
    Based on the comments and information received during and after the 
rulemakings for NSPS for both CI and SI ICE, the EPA believes in this 
circumstance and with certain safeguards, it is appropriate to provide 
flexibility to owners and operators to follow alternative operation and 
maintenance procedures. Therefore, the EPA is revising the regulations 
to allow owners and operators to develop their own operation and 
maintenance plans as an alternative to following manufacturer operation 
and maintenance procedures. However, if an owner/operator decides to 
take this approach, the EPA will need greater assurance that the engine 
is meeting emission requirements because the owner/operator will not be 
operating according to the operation and maintenance instructions 
included in the engine manufacturer's certification. Thus, owner/
operators using this approach will generally be subject to further 
testing of their engines and will be required to keep maintenance plans 
and records. Engines greater than 500 HP are required to conduct a 
performance test within 1 year of startup (or within 1 year after an 
engine and control device is no longer installed, configured, operated, 
and maintained in accordance with the manufacturer's emission-related 
written instructions) to demonstrate compliance with the emission 
standards, and also have to conduct subsequent performance testing 
every 8,760 hours or 3 years (whichever comes first) thereafter. These 
engines are also required to keep a maintenance plan and records of 
conducted maintenance.
    Engines greater than or equal to 100 HP and less than or equal to 
500 HP are required to conduct a performance test within 1 year of 
startup (or within 1 year after an engine and control device is no 
longer installed, configured, operated, and maintained in accordance 
with the manufacturer's emission-related written instructions) to 
demonstrate compliance with the emission standards and in addition are 
required to keep a maintenance plan and records of conducted 
maintenance. Engines below 100 HP operating in a non-certified manner 
do not have to conduct further performance testing, but are required to 
keep a maintenance plan and records, and if the owner/operator does not 
install and configure the engine and control device according to the 
manufacturer's emission-related written instructions, then the owner/
operator must conduct a performance test to demonstrate compliance with 
the applicable emission standards within 1 year of such action.
    Owners and operators have the ability to adjust engine settings 
outside of manufacturer settings as long as they demonstrate the 
engines comply with the standards at those settings with a performance 
test. Parties also noted that the operation and maintenance 
requirements extended beyond emission-related operation and maintenance 
and extended to operation and maintenance of all aspects of the engine, 
which the parties believed should be beyond the scope of the 
regulation. The EPA agrees that the operation and maintenance 
requirements of the NSPS should be restricted to emission-related 
operation and maintenance, and is revising the regulations accordingly.
    The EPA notes that if the engine settings are adjusted outside of 
the manufacturer's specifications, the engine is no longer considered 
to be a certified engine. The engine manufacturer is no longer 
considered responsible for the engine being in compliance with the 
applicable emission standards, and the emissions warranty for the 
engine becomes void.

D. Temporary Replacement Engines

    The EPA received comments during and after the initial CI NSPS 
rulemaking and during the SI NSPS rulemaking indicating that there was 
some confusion regarding the status of temporary engines (i.e., 
generally engines in one location for less than 1 year) under the EPA's 
regulations. Further, there was concern that for those temporary 
engines that were considered stationary under the definitions of 
stationary and nonroad engine, because they replaced other stationary 
engines during periods when the main engines were off-line (e.g., for 
maintenance work), owners and operators of major sources would have 
little or no ability to oversee the operations of these temporary 
engines, as they were generally owned and maintained by other entities.
    The EPA notes that except for certain instances (e.g., engines at 
seasonal sources or engines that replace stationary engines at a 
location), engines in one location for less than 1 year are generally 
considered to be mobile nonroad engines under the EPA's regulatory 
definitions of nonroad engine and stationary engine, and, therefore, 
the NSPS and other regulations applicable to stationary engines are not 
applicable to such engines. Examples of such nonroad engines are 
engines that are brought to a stationary major source for less than 1 
year for purposes of general maintenance or construction.
    Portable engines that replace existing stationary engines at the 
same location on a temporary basis and that are intended to perform the 
same or similar

[[Page 37959]]

functions are considered stationary engines. This provision allows the 
permitting authority to count the emissions of the temporary unit in 
the emissions from the stationary source, as it would for the permanent 
unit. This prevents sources from avoiding the counting of such units in 
its projected or actual emissions. The EPA agrees with comments that 
with regard to temporary replacement engines, which are generally 
portable and moved from place to place, it is most appropriate that 
these engines, though considered stationary, should be allowed under 
the NSPS to meet requirements for mobile nonroad engines. These sources 
are not under the long-term control (or in many cases the short-term 
control) of the local source, and, therefore, it is appropriate to hold 
them to the requirements for similar sources that are mobile in 
character. The EPA also notes that under the pre-existing general 
provisions for 40 CFR part 60, the fact that an engine moves from place 
to place does not, by the sole basis of that movement, make the engine 
a ``new'' engine for the purposes of the NSPS.

E. Requirements for Engines Located in Remote Areas of Alaska

    In the original final NSPS, the EPA agreed to delay the sulfur 
requirements for diesel fuel intended for stationary ICE in remote 
areas of Alaska not accessible by the Federal Aid Highway System (FAHS) 
(``remote Alaska'') until December 1, 2010, except that any 2011 model 
year and later stationary CI engines operating in remote Alaska prior 
to December 1, 2010, would be required to meet the 15 ppm sulfur 
requirement for diesel fuel. This approach was consistent with the 
approach that was used for nonroad and highway engines in remote 
Alaska. The EPA also included a special section in the final rule that 
specified that until December 1, 2010, owners and operators of 
stationary CI engines located in Alaska should refer to 40 CFR part 69 
to determine the diesel fuel requirements applicable to such engines.
    In addition, the original final regulations included language that 
allowed Alaska to submit for the EPA approval through rulemaking 
process an alternative plan for implementing the requirements of this 
regulation for public-sector electrical utilities located in remote 
areas of Alaska not accessible by the FAHS. The alternative plan needed 
to be based on the requirements of section 111 of the CAA including any 
increased risks to human health and the environment, and also needed to 
be based on the unique circumstances related to remote power 
generation, climatic conditions, and serious economic impacts resulting 
from implementation of the final NSPS.
    The EPA also included an option in the original final NSPS for 
stationary CI engines that allowed owners and operators of pre-2011 
model year engines located in remote areas of Alaska to petition the 
Administrator to use any fuels mixed with used oil that do not meet the 
fuel requirements in Sec.  60.4207 of the final rule beyond the 
required fuel deadlines. The owner or operator was required to show 
that there is no other place to burn the used oil. Each petition, if 
approved, was valid for a period of up to 6 months.
    The EPA communicated with officials from the State of Alaska on 
several occasions following the promulgation of the final rule, and 
gave the State of Alaska an extension from the original deadline of 
January 11, 2008, to provide its alternative plan for remote Alaska to 
the EPA. On October 31, 2008, the EPA received Alaska's request for 
several revisions to the NSPS as it pertains to engines located in the 
remote part of Alaska not served by the FAHS.
    In particular, the State of Alaska requested the following:
     Allow NSPS owner/operator requirements to apply only to 
model year 2011 and later engines.
     Maintain a December 1, 2010, deadline for transition of 
regulated engines to ULSD.
     Authorize continued use of single circuit jacketwater 
marine diesel engines for prime power applications.
     Remove limitations on using fuels mixed with used 
lubricating oil that do not meet the fuel requirements of 40 CFR part 
60, subpart IIII.
     Review emission control design requirements needed to meet 
new NSPS emission standards, including the possibility of removing or 
delaying emissions standards requiring advanced exhaust gas emissions 
aftertreatment technologies until the technology is proven for remote 
and arctic applications.
    The EPA notes the following information provided by the State of 
Alaska in its request. In general, the State noted that over 180 remote 
communities in Alaska that are not accessible by the FAHS rely on 
diesel engines and fuel for electricity. These communities are 
scattered over long distances in remote areas and are not connected to 
population centers by road or power grid. These communities are located 
in the most severe arctic environments in the United States.
    Regarding the request that owners and operator requirements apply 
only to model year 2011 and later engines, the State of Alaska focused 
on two particular requirements for pre-2011 engines: The requirement 
that pre-2011 engines that are manufactured after April 1, 2006, use 
ULSD beginning on December 1, 2010; and the requirement that after 
December 31, 2008, owners and operators may not install engines that do 
not meet the applicable requirements for 2007 model year engines.
    The State of Alaska noted that Alaska village power plants are 
typically operated by a single part-time operator with an alternate, 
that there is a high rate of turnover among plant operators, and that 
operators have limited training, expertise or resources. The State of 
Alaska notes that pre-2011 engines will all be fueled, prior to 
December 1, 2011, with the same fuel. The State of Alaska stated that 
it would greatly simplify operations to coordinate the fuel 
requirements with the introduction of 2011 model year engines, rather 
than retroactively requiring some, but not all, earlier engines to meet 
the fuel requirements. It would also facilitate the smoother transition 
to ULSD fuel, rather than requiring numerous engines to all meet the 
requirements at the same time. The State of Alaska noted that there is 
no technological requirement for pre-model year 2011 engines to use 
aftertreatment, and thus no technological need to use ULSD. The EPA 
agrees that the requested revision will reduce the complexity of the 
regulations and that ULSD is not technologically necessary for engines 
that are not required to meet the Tier 4 emission standards for PM. As 
discussed in section V.C., in response to comments during this 
rulemaking requesting relief from the requirement to meet Tier 4-
equivalent PM standards, the EPA is requiring new engines in remote 
areas of Alaska to meet the more stringent PM standards and use ULSD 
beginning with 2014 model year engines. Therefore, the EPA is 
finalizing a requirement that 2014 model year and later engines use 
ULSD, rather than 2011 model year and later that was proposed. The EPA 
also notes that the requirement to use ULSD for 2014 and later model 
year engines will eventually lead to a complete turnover of the fuel 
used in the remote villages.
    The State of Alaska notes that the planning, construction and 
operation of engines in remote Alaska is complex. The timeframe for 
these projects, which are coordinated among several governmental 
entities, typically exceeds 3 years. The State of Alaska notes that 
several projects that were designed and funded based on pre-2007 model 
year

[[Page 37960]]

engines were not installed prior to December 31, 2008. Therefore, the 
State of Alaska requested that the deadline be moved to December 2010. 
While the EPA understands that some extra time may be needed to allow 
for these pre-existing projects to go forward with pre-2007 engines, 
the EPA does not believe the State of Alaska has justified a 2-year 
extension, beyond the 2 years already provided in the regulations. 
However, the EPA believes that a 1-year extension would be appropriate. 
The EPA is, therefore, finalizing a 1-year extension for owners and 
operators in remote Alaska to install pre-2007 model year engines.
    Regarding its request for continued use of single circuit 
jacketwater marine diesel engines for prime power applications, the 
State of Alaska notes that remote villages in Alaska use combined heat 
and power cogeneration plants, which are vital to their economy, given 
the high cost of fuel and the substantial need for heat in that 
climate. Heat recovery systems are used with diesel engines in remote 
communities to provide heat to community facilities and schools. 
Marine-jacketed diesel engines are used wherever possible because of 
their superior heat recovery and thermal efficiency. The State of 
Alaska has noticed great reductions in heat recovery when using Tier 3 
non-marine engines. The State notes that reductions in fuel efficiency 
will lead to greater fuel use and greater emissions from burning extra 
heating oil. The EPA agrees with the State that there are significant 
benefits from using marine engines, and is finalizing a revision that 
will allow engines in remote Alaska to use marine-certified engines. 
However, as the State of Alaska notes, marine-certified engines, 
particularly those below 800 HP, are not required to meet more 
stringent requirements for reduction of PM emissions, which is the most 
significant pollutant of concern in these areas. Therefore, the EPA is 
requiring that owners and operators of 2014 model year and later 
engines must either be certified to Tier 4 standards (whether land-
based nonroad or marine) or must install PM reduction technologies on 
their engines to achieve at least 85 percent reduction in PM.
    Regarding the issue of using aftertreatment technologies that the 
State of Alaska says have not been tested in remote arctic climates, 
the EPA notes that the original request from the State of Alaska was 
particularly concerned with NOX standards that would likely 
entail the use of SCR in remote Alaska. NOX reductions are 
particularly important in areas where ozone is a concern, because 
NOX is a precursor to ozone. However, the State of Alaska, 
and remote Alaska in particular, does not have any significant ozone 
problems. Moreover, the use of SCR entails the supply, storage and use 
of a chemical reductant, usually urea, that needs to be used properly 
in order to achieve the expected emissions reductions, and that may 
have additional operational problems in remote arctic climates. As 
noted above, these villages are not accessible by the FAHS and are 
scattered over long distances in remote areas and are not connected to 
population centers by road or power grid. The villages are located in 
the most severe arctic environments in the United States and they rely 
on stationary diesel engines and fuel for electricity and heating, and 
these engines need to be in working condition, particularly in the 
winter. While the availability of reductant is not a problem in the 
areas on the highway system, its availability in remote villages, 
particularly in the early years of the Tier 4 program, may be an issue, 
which is notable given the importance of the stationary engines in 
these villages. Furthermore, the costs for the acquisition, storage and 
handling of the chemical reductant would be greater than for engines 
located elsewhere in the United States due to the remote location and 
severe arctic climate of the villages. In order to maintain proper 
availability of the chemical reductant during the harsh winter months, 
new heated storage vessels may be needed at each engine facility, 
further increasing the compliance costs for these remote villages. 
Given the issues that would need to be addressed if SCR were required, 
and the associated costs of this technology when analyzed under NSPS 
guidelines, the EPA understands the State of Alaska's argument that it 
is inappropriate to require such standards for stationary engines in 
remote Alaska.\1\ Therefore, the EPA is not requiring owners and 
operators of new stationary engines to meet the Tier 4 standards for 
NOX in these areas. However, owners and operators of model 
year 2014 and later engines that do not meet the Tier 4 PM standards 
would be required to use PM aftertreatment, as discussed above. The use 
of PM aftertreatment will also achieve reductions in CO and 
hydrocarbons (HC).
---------------------------------------------------------------------------

    \1\ Note that this action applies to stationary engines only; it 
is unlikely that such an approach would be appropriate for mobile 
engines, given that they are less permanent in a village and can 
move in and out of areas as work requires, and because the EPA has 
less ability to enforce such an approach for mobile sources, where 
the EPA does not regulate the owner or operator directly.
---------------------------------------------------------------------------

    Finally, regarding allowing owners and operators to blend up to 
1.75 percent used oil into the fuel system, the State notes that there 
are no permitted used oil disposal facilities in remote Alaskan 
communities. The State has developed a cost-effective and reliable 
used-oil blending system that is currently being used in many remote 
Alaskan communities, disposing of the oil in an environmentally 
beneficial manner and capturing the energy content of the used oil. The 
absence of allowable blending would necessitate the shipping out of the 
used oil and would risk improper disposal and storage, as well as 
spills.
    According to the State, blending waste oil at 1.75 percent or less 
will keep the fuel within American Society for Testing and Materials 
(ASTM) specifications if the sulfur content of the waste oil is below 
200 ppm. The State acknowledges the need for engines equipped with 
aftertreatment devices to use fuel meeting the sulfur requirements. The 
EPA agrees that the limited blending of used oil into the diesel fuel 
used by stationary engines in remote Alaska is an environmentally 
beneficial manner of disposing of such oil and is of little to no 
concern when kept within appropriate limits. Therefore, the EPA is 
finalizing amendments that permit the blending of fuel oil at such 
levels for engines in remote Alaska. The used oil must be ``on-spec,'' 
i.e., it must meet the on-specification levels and properties in 40 CFR 
279.11.
    The EPA agrees that the circumstances in remote Alaska require 
special rules. The EPA is, therefore, promulgating several amendments 
for engines used in remote Alaska:
     Exempting all pre-2014 model year engines from diesel fuel 
sulfur requirements;
     Allowing owners and operators of stationary CI engines 
located in remote areas of Alaska to use engines certified to marine 
engine standards, rather than land-based nonroad engine standards; and
     Removing requirements to use aftertreatment devices for 
NOX, in particular, SCR, for engines used in remote Alaska;
     Removing requirements to use aftertreatment devices for PM 
until the 2014 model year; and
     Allowing the blending of used lubricating oil, in volumes 
of up to 1.75 percent of the total fuel, if the sulfur content of the 
used lubricating oil is less than 200 ppm and the used lubricating oil 
is ``on-spec,'' i.e., it meets the on-specification levels and 
properties of 40 CFR 279.11.

[[Page 37961]]

F. Reconstruction

    The EPA is also finalizing amendments to the NSPS that require 
reconstructed engines to meet the emission standards for the model year 
in which the reconstruction occurs if the reconstructed engine meets 
either of the following criteria:
     The fixed capital cost of the new and refurbished 
components exceeds 75 percent of the fixed capital cost of a comparable 
new engine; or
     The reconstructed engine consists of a previously used 
engine block with all new components.
    The final rule also clarifies that the provisions for modified and 
reconstructed engines apply to anyone who modifies or reconstructs an 
engine, including engine owners/operators, engine manufacturers, and 
anyone else. The final rule also adds additional clarification 
regarding what standards are applicable for modified or reconstructed 
engines.

G. Minor Corrections and Revisions

    The EPA is making several minor revisions in this rule to correct 
mistakes in the initial rule or to clarify the rule. The revisions are 
listed below:
     Replacing the term ``useful life'' with ``certified 
emissions life,'' for purposes of clarity;
     Revising Table 3 in the in 40 CFR part 60, subpart IIII to 
account for a mistake in how Table 3 characterized the certification 
requirements for high speed fire pump engines in the original final 
rule;
     Revising the definition of ``emergency stationary internal 
combustion engine'' in the NSPS for stationary CI ICE to include the 
allowance for 50 hours of non-emergency operation, to be consistent 
with the definition of emergency stationary internal combustion engine 
in the NSPS for stationary SI ICE and the National Emission Standards 
for Hazardous Air Pollutants (NESHAP) for Stationary Reciprocating 
Internal Combustion Engines (RICE) (40 CFR part 63, subpart ZZZZ);
     Revising the requirement for emergency engines to install 
non-resettable hour meters such that emergency engines that meet the 
requirements for non-emergency engines do not have to install the hour 
meters;
     Revising the applicability provisions to make clearer the 
EPA's requirement that all owners and operators of new sources must 
meet the deadlines for installation of compliant stationary engines;
     Revising certain provisions of the NSPS for stationary SI 
engines, particularly concerning definitions and compliance by owners 
and operators of such engines, to correct clear errors and to ensure 
consistency where appropriate for the regulation of stationary ICE; and
     Adding a definition of ``installed'' to provide clarity to 
the provisions regarding installing engines produced in previous model 
years.

IV. Summary of Significant Changes Since Proposal

A. Definitions

    The EPA proposed to add a definition for ``reconstruct'' that was 
specific for the NSPS for stationary ICE. In the final rule, the EPA is 
not including the proposed definition for reconstruct, and, instead, 
will continue to use the definition for reconstruction found in the 
General Provisions of 40 CFR part 60, specifically at 60.15 of that 
part. The EPA also proposed to add a definition for ``date of 
manufacture'' that would have assigned a new date of manufacture for 
reconstructed engines if any of the following criteria were met: the 
crankshaft was removed as part of the reconstruction; the fixed capital 
cost of the new and refurbished components exceeded 75 percent of the 
fixed capital cost for a comparable new engine; the engine serial 
number was removed; or the engine was produced using all new components 
except for the engine block. The definition for ``date of manufacture'' 
that the EPA is finalizing specifies that a new date of manufacture is 
assigned for a reconstructed engine if the fixed capital cost of the 
new and refurbished components exceeded 75 percent of the fixed capital 
cost for a comparable entirely new facility, or if the engine was 
produced using all new components except for the engine block.
    The definition for ``installed'' that the EPA is finalizing is also 
different from the proposed definition. The definition that the EPA 
proposed stated that an engine is considered installed when it is 
placed and secured at the location where it is intended to be operated; 
piping and wiring for exhaust, fuel, controls, etc. are installed and 
all connections are made; and the engine is capable of being started. 
The definition for ``installed'' in the final rule does not include the 
conditions that the piping and wiring are installed and the engine is 
capable of being started.
    The EPA is also correcting a typographical error in the definition 
for ``liquefied petroleum gas'' in the NSPS for stationary SI ICE, 40 
CFR part 60, subpart JJJJ. The definition should have the word ``or'' 
instead of the word ``of'' after the phrase ``* * * obtained as a by-
product in petroleum refining. * * *'' This final rule corrects that 
typographical error.

B. Emission Standards and Fuel Requirements

    In the final rule, the EPA is revising the fuel requirements for 
engines subject to the NSPS for stationary CI ICE. The rule as 
originally promulgated required owners and operators of stationary CI 
ICE to use diesel fuel that meets the requirements of 40 CFR 80.510(b) 
for nonroad diesel fuel beginning on October 1, 2010. Facilities could 
petition for approval to use existing inventories of non-compliant fuel 
for a period of up to 6 months at a time. Facilities were required to 
submit a new petition if additional time was needed. The EPA received a 
number of petitions for extensions of the October 1, 2010, deadline 
from facilities that operate emergency engines that are subject to the 
NSPS for stationary CI ICE. In the petitions, the facilities indicated 
that they only operate the engines for a few hours each year, and that 
it may take a period of years to use up the existing fuel in their 
tanks, since they keep a supply of fuel on hand that would be adequate 
for the engines in the event of an emergency. Petitioners also noted 
the great expense of draining the remaining fuel and purchasing 
replacement fuel, while the drained fuel would likely be used in other 
applications that did not need to meet the fuel requirements of the 
NSPS. A petitioner requested that the EPA change the rule so that 
facilities were required to purchase diesel fuel that was compliant 
with 40 CFR 80.510(b) after October 1, 2010, but could use any fuel 
remaining in its tanks until it was depleted. Based on the information 
provided in the petitions, the EPA is revising the fuel requirement for 
stationary CI ICE subject to the NSPS. The final rule amends the 
requirement to specify that owners and operators must purchase fuel 
that meets the requirements of 40 CFR 80.510(b) beginning on October 1, 
2010.
    The EPA is also finalizing a different deadline than proposed for 
engines with a displacement greater than or equal to 30 l/cyl to 
transition to fuel with a sulfur content of 1,000 ppm. The EPA proposed 
to allow owners and operators of these engines to begin using 1,000 ppm 
sulfur content fuel beginning on January 1, 2014. The final rule allows 
owners and operators to begin using 1,000 ppm sulfur content fuel 
beginning June 1, 2012.
    Finally, the EPA is finalizing a different deadline for new engines 
in remote areas of Alaska to begin using ULSD than was proposed. The 
EPA proposed to require the use of ULSD

[[Page 37962]]

beginning with 2011 model year engines; the final rule requires the use 
of ULSD beginning with 2014 model year engines. The EPA is also 
providing additional time before requiring stationary engines located 
in remote areas of Alaska to meet more stringent PM standards that are 
based on the use of aftertreatment.

C. Requirements for Emergency Engines

    The EPA proposed to amend the definition for ``emergency stationary 
internal combustion engine'' and the allowances for maintenance/testing 
and non-emergency operation for such engines to be consistent with the 
provisions promulgated in the NESHAP for existing stationary RICE at 40 
CFR part 63, subpart ZZZZ. The EPA is only finalizing a portion of the 
proposed revisions to the emergency engine definition. The EPA is 
finalizing the provision allowing 50 hours of non-emergency service for 
stationary CI engines subject to the NSPS, in order to make the 
emergency engine provisions for new CI engines consistent with those 
for new SI engines and existing CI and SI engines. At this time, the 
EPA is not finalizing the proposed provision allowing 15 hours for 
demand response operation for emergency stationary engines. The EPA 
included a similar provision for emergency engines in the March 3, 
2010, amendments to the stationary RICE NESHAP (75 FR 9648), and 
subsequently proposed to amend the stationary engine NSPS to be 
consistent with the stationary RICE NESHAP. The EPA received two 
petitions for reconsideration of the 15-hour allowance for demand 
response in the stationary RICE NESHAP, and is currently reconsidering 
its decision to allow emergency engines to operate for 15 hours per 
year as part of an emergency demand response program. The EPA is 
deferring taking final action on including this provision in the 
stationary ICE NSPS pending the resolution of the reconsideration 
process on the stationary RICE NESHAP. The EPA will address this issue 
as it affects the CI and SI engine NSPS emergency engine provisions as 
part of that reconsideration process.

D. Other

    In the proposed rule, the EPA requested comment on the need for 
stationary engines in marine offshore settings to use engines meeting 
the marine engine standards, rather than land-based engine standards. 
The comments that were received in response to the EPA's request all 
supported allowing stationary engines in marine offshore settings to 
use engines meeting the marine engine standards. In the final rule, the 
EPA is including provisions that would allow stationary engines used in 
marine offshore settings to meet marine engine standards.
    The EPA received comments on the proposed amendments requesting 
several changes to 40 CFR part 60, subpart JJJJ that were not related 
to this rule. While the EPA is generally not making these changes, as 
they are beyond the scope of this rule and would require substantive 
analysis, the EPA is making certain revisions to correct clear errors 
(e.g., changing > signs to < signs where appropriate) and clarifying 
that determining the exhaust flowrate is not required if the engine is 
being tested to show compliance with the concentration-based (ppm) 
standards for NOX, CO, and VOC.

V. Summary of Responses to Major Comments

A. Fuel Requirements for Engines With a Displacement Greater Than or 
Equal to 30 L/Cyl

    Comment: One commenter supported a fuel limit of 1,000 ppm sulfur 
content for engines with a displacement at or above 30 l/cyl. The 
commenter agreed that it is appropriate to align fuel requirements for 
stationary engines with a displacement at or above 30 l/cyl with those 
that are in the IMO marine engine standards, since the stationary 
engine emission standards are also being aligned with IMO marine engine 
standards. However, the commenter asked that the EPA require that this 
limit become effective immediately and not in 2014, as proposed. The 
commenter claimed that 500 ppm sulfur fuel, which is the sulfur level 
stationary engines at or above 30 l/cyl currently must meet for the 
fuel they use, will become very limited and perhaps unavailable after 
the 15 ppm sulfur fuel requirements take effect in October 2010 for 
most mobile and stationary engines. Engines of large displacement are 
not designed to operate on 15 ppm sulfur fuel, the commenter argued, 
therefore, appropriate fuel for these engines may not be available, or 
if it is, will be significantly more costly. To ensure the availability 
of appropriate fuel, the commenter asked that the EPA allow engines 
with a displacement at or above 30 l/cyl to use 1,000 ppm sulfur fuel 
immediately.
    Response: The EPA agrees that it would be appropriate to require 
that stationary engines with a displacement of 30 l/cyl or more limit 
the sulfur content in the fuel to 1,000 ppm beginning earlier than 
2014, which is the timeframe that was proposed. However, the EPA 
disagrees with the commenter's logic and that the requirement should 
become effective immediately. Diesel fuel containing 500 ppm sulfur 
will be the designated off-spec fuel within the diesel stream until 
2014 and should be available at least for locomotives and marine 
engines until June 1, 2012. Therefore, the EPA believes it is 
appropriate to finalize the 1,000 ppm fuel requirement for large 
displacement engines, but require that these engines begin using this 
fuel on June 1, 2012.

B. Operating and Maintenance Requirements

    Comment: One commenter expressed concern about the proposal that 
for certified engines, owners and operators would be allowed to develop 
and follow their own operation and maintenance (O&M) procedures as an 
alternative to following the manufacturer's O&M procedures. The 
commenter recommended that engines that do not follow the 
manufacturer's O&M procedures be considered as operating in a non-
certified manner and subject to initial performance testing 
requirements. The commenter indicated that it is supportive of 
providing additional flexibility, but that in those cases where an 
owner or operator opts to take an alternative O&M approach, which 
differs from what the manufacturer recommends for the engine, the 
engine manufacturer or certificate holder should no longer be 
responsible for emissions compliance. According to the commenter, the 
EPA should make that clarification as to who is responsible for the 
emissions from the engine and if operated differently than recommended 
by the manufacturer, the engine should no longer be classified as a 
certified engine.
    Response: The EPA agrees that the engine manufacturer should not be 
held responsible once owners and operators of a certified engine no 
longer operate and maintain the engine and control device according to 
the manufacturer's O&M procedures. This is consistent with the language 
in section 207 of the CAA and 40 CFR 1068.505, regarding mobile source 
engines, that specifies the EPA not require a recall of engines by the 
manufacturer unless the EPA determines that a substantial number of 
engines, although properly maintained and used, do not conform to 
emission regulations. The EPA thinks that it is clear in the rule 
language that the owner/operator, not the manufacturer, is required to 
show compliance in such situations, as was specifically laid out in 
60.4211(g) of the proposed rule. Further,

[[Page 37963]]

the EPA stated in the preamble to the proposed rule that engines 
operated in this manner would be considered non-certified engines and 
generally subject to performance testing (see 75 FR 32615, middle 
column).

C. Engines Located in Remote Alaska

    Comment: One commenter supported allowing used oil blending under 
the CI NSPS. Blending used oil for burning in the facility's own engine 
is important and decreases risks related to disposal and spills in 
areas that have limited resources available to deal with such costs, 
the commenter said. According to the commenter, a significant 
environmental concern in remote Alaska is the improper disposal of used 
oil. In most remote Alaska communities, there are no permitted used oil 
disposal facilities and the cost of exporting used oil is burdensome 
and can be the same price or more than purchasing new oil, the 
commenter noted. The commenter recommended that used fuel blending be 
allowed in the rule at a maximum blend level of 1.75 percent.
    Response: The EPA agrees that the limited blending of used oil into 
the diesel fuel used by stationary engines in remote areas of Alaska is 
an environmentally beneficial manner of disposing of such oil. 
Therefore, the EPA has included a provision in the final rule that 
allows the blending of fuel oil for engines in remote Alaska, in 
volumes of up to 1.75 percent of the total fuel. The sulfur content of 
the used lubricating oil must be less than 200 ppm, and the used 
lubricating oil must be is ``on-spec,'' i.e., it must meet the on-
specification levels and properties in 40 CFR 279.11.
    Comment: One commenter expressed concern over the proposed 
requirements for small remote power plants in Alaska that would 
necessitate aftertreatment in order to meet the PM limits. The 
commenter's concern regarding aftertreatment for PM is based on the 
majority of small remote power plans being un-staffed and the technical 
capability of staff being minimal and including only basic maintenance 
tasks such as maintaining the oil, filter, belts and hoses. In 
addition, the commenter was concerned that the exhaust aftertreatment 
used to reduce PM would limit the ability to burn used oil in the 
engine, and could also pose a risk to the reliability of the engine. 
The commenter also believed that the installation and maintenance costs 
for PM aftertreatment were unreasonable.
    Response: The EPA disagrees with the commenter that PM limits that 
necessitate the use of aftertreatment like CDPF should not be required 
at all for stationary CI engines located in remote areas of Alaska. The 
need for PM control was in the commenter's original request to the EPA, 
noting that PM is the most significant pollutant of concern in remote 
areas of Alaska. Stationary CI engines are often in very close 
proximity to the towns and the diesel PM emissions, which are highly 
toxic, can fall on the towns. Substantial health impacts are associated 
with diesel PM emissions and the EPA does not believe it is appropriate 
to reduce the stringency of PM requirements in remote Alaska.
    Regarding the concerns raised by the State of Alaska regarding the 
feasibility and cost of installing and operating CDPF in remote 
villages, the EPA is providing additional time in the final rule before 
new stationary engines in remote areas of Alaska are required to meet 
PM standards that would require CDPF. The use of CDPF for new nonroad 
and stationary diesel engines in the United States will be phased in 
from 2011 to 2015. Waiting until there is more widespread experience 
with operating and maintaining CDPF would allow time for Alaska's 
concerns regarding the feasibility of maintaining CDPF on engines in 
remote areas to be addressed. The type of engines most often used to 
power the remote villages is currently required by the NSPS to meet PM 
standards based on the use of CDPF beginning with the 2011 or 2012 
model year, depending on the engine size. Providing a delay until the 
2014 model year for engines located in remote Alaskan villages would 
provide State with 2 to 3 years to gain experience with the operation 
of the controls and develop the equipment infrastructure needed to 
properly operate and maintain the CDPF. In response to this comment, 
the EPA consulted with vendors of CDPF, who indicated that the 
installation and maintenance costs for the systems are not as high as 
the estimates provided by the State of Alaska.\2\
---------------------------------------------------------------------------

    \2\ See memorandum titled ``Summary of Calls with Vendors of 
Diesel Particulate Filters (DPF)'' in docket EPA-HQ-OAR-2010-0295.
---------------------------------------------------------------------------

    The EPA recognizes that the blending of used oil into diesel fuel 
is a concern for engines equipped with CDPF; however, the EPA believes 
that given the restrictions in the rule for used oil blending (no more 
than 1.75 percent of total fuel and no more than 200 ppm sulfur in the 
oil), the increase in sulfur caused by the blending should not be a 
significant concern for the operation of CDPF-equipped engines.

D. Emission Standards for Marine Engines

    Comment: Several commenters provided recommendations on how to 
treat stationary engines used in marine offshore settings. The 
commenters said that marine engines should not be subject to land-based 
standards and indicated support for revisions to allow the use of 
marine based standards as opposed to NSPS for offshore platform 
installations. The commenters indicated that these engines are normally 
nonroad engines that are subject to marine engine standards. The 
commenters said that if the marine engine is used in a stationary 
manner, the commenters were supportive of language being added to 
indicate that stationary engines in marine offshore settings may comply 
with applicable marine engine standards as opposed to the land-based 
standards.
    Response: The EPA requested comment on the need for stationary 
engines in marine offshore settings to use engines meeting the marine 
engine standards, rather than land-based engine standards. Based on 
comments received on this issue, the EPA agrees that it would be 
appropriate to allow stationary engines used in marine offshore 
settings to meet marine engine standards. The EPA understands that 
engines used in these settings are generally certified to marine 
standards and that it may not be possible to know how an engine will be 
used throughout its life when it is first used. The EPA does not see a 
need to require engines utilized in the same marine offshore setting to 
be certified to different standards based solely on the time an engine 
remains in one location. It therefore is appropriate to require engines 
used in both mobile and stationary marine offshore applications to be 
able to meet the same standard.

E. Test Methods

    Comment: One commenter said that the test method for stationary 
engines with a displacement at or above 30 l/cyl needs to be changed 
from Method 5 to Method 5B or Method 17. The main reason the commenter 
believes Method 5 is not suitable is because it requires the use of 
glass fiber filters maintained at 120 degrees Celsius ([deg]C) [250 
degrees Fahrenheit ([deg]F)]. The method also requires that in sources 
that have sulfur dioxide (SO2) or sulfur trioxide 
(SO3) that the filter material be unreactive to these 
pollutants and International Organization for Standardization (ISO) 
method 9096 2003 does not recommend glass fiber filter use where this 
reaction occurs. The commenter went on to say

[[Page 37964]]

that the temperature required by Method 5 is generally much lower than 
normal exhaust temperatures from large displacement engines. This 
necessitates cooling of the exhaust gas in order to use Method 5, the 
commenter said, which would lead to the formation of additional 
condensation particles that would affect the sampling results. The 
commenter argued that the method would not yield reproducible results 
and recommended that due to inconsistencies, the EPA should allow 
alternative methods. The commenter recommended that the EPA raise the 
PM sampling temperature in Method 5 to a minimum of 160 [deg]C, which 
essentially means changing Method 5 to Method 5B, and also allow 
stationary engines to use Method 17 as an alternative.
    Response: The EPA disagrees with the comment that EPA Method 5 does 
not provide accurate and precise measurements of PM. The statements in 
EPA Method 5 and ISO 9096 2003 regarding the selection of filtration 
media that are unreactive to SO3 are intended to ensure that 
the proper filter media are used. When acceptable filter media are 
selected, including glass fiber filters that are unreactive to 
SO2 or SO3, EPA Method 5 has been shown to 
provide reproducible results irrespective of the filtration temperature 
chosen.
    The EPA also disagrees that EPA Method 5 cannot achieve a 
filtration temperature of 120 [deg]C (250 [deg]F) since there are no 
procedures for cooling the sample gas from the stack temperature to the 
required filtration temperature. EPA Method 5 is silent on the method 
for cooling the sample gas, as this is left to the discretion of the 
source test individual. The method employed depends upon the stack gas 
temperature, the required filtration temperature, and the equipment 
available to the individual test contractor. In most situations, no 
special procedures are required since sufficient cooling is achieved by 
normal air exposure of the probe and filter holder. Where filtration 
temperature is likely to exceed the method specified temperature, 
contractors have used specially constructed air cooled or water cooled 
probes to achieve the proper temperature.

F. Definitions

    Comment: Several commenters were concerned with the proposed 
definition of ``reconstruct.'' According to the commenters, the 
proposed definition would result in stationary engines currently not 
subject to the rule becoming subject to NSPS after conducting routine 
maintenance, repair, rework, and overhaul. Several commenters stated 
that the EPA has not provided sufficient rationale for adding this new 
definition and the term is significantly different from other NSPS 
definitions and applicability determinations regarding reconstruction. 
Two commenters said that the proposed definition excludes the cost of 
fundamental components from the fixed capital costs, such as the 
engineering costs, construction and site installation and startup 
costs, and the costs associated with auxiliary components that service 
or that are critical to the engine's operation. Commenters requested 
that the EPA maintain the definitions in 40 CFR 60.15(b) and 40 CFR 
60.15(c), for reconstruction and fixed capital cost, respectively, in 
the final NSPS for stationary CI and SI engines.
    Response: The EPA proposed to add a definition of ``reconstruct'' 
to the CI and SI NSPS as an attempt to clarify the meaning of 
reconstruction. The EPA's objective with the proposal was to provide a 
more specific definition applicable to stationary engines rather than 
the broader definition provided in the General Provisions of 40 CFR 
part 60. The proposed definition was intended to clarify how to conduct 
the reconstruction analysis by specifically proposing to include a 
definition that would be applicable to stationary engines subject to 
NSPS. The EPA believed that providing a specific definition applicable 
only to stationary engines would be beneficial by bringing clarity to 
how reconstruction is determined in the stationary engine setting.
    The EPA did not expect the proposed change to be controversial nor 
did the EPA anticipate that the proposed change would cause such 
significant concern among affected sources. However, as illustrated in 
the summary of comments on this issue, several affected stakeholders 
strongly opposed the EPA's suggested changes to the historical 
definition of reconstruction. Based on the extensive concerns provided 
by commenters and subsequent information the EPA has received from 
stakeholders after the proposal, the EPA determined that it is 
appropriate to not include the proposed definition of ``reconstruct'' 
in the final rule. Instead, the EPA is finalizing the rule using the 
definition of ``reconstruction'' from the General Provisions of 40 CFR 
part 60. Again, the EPA intended to provide more guidance than what was 
originally provided in the rule on reconstruction; however, it is 
nearly impossible to capture all potential situations in a definition. 
The EPA believes it is appropriate to continue to rely on the 
definition in 40 CFR 60.15. Therefore, the EPA is not finalizing the 
proposed definition of ``reconstruct.''
    Comment: A number of commenters took issue with the criteria in the 
proposed definition of the ``date of manufacture'' and asked that the 
definition either be removed or revised. Commenters said that the 
proposed changes to the date of manufacture definition constitute 
significant concern for industry because of the cost and operational 
impacts, plus regulatory confusion the commenters believe the changes 
create. Commenters indicated that the criteria in the definition are 
flawed and inconsistent with previous definitions of reconstruction. 
Several commenters were of the opinion that it is not appropriate to 
include the removal of the crankshaft as criteria for designating an 
engine being subject to new standards. This component is frequently 
removed during inspection and maintenance, according to the commenters, 
who suggested that the criteria related to the crankshaft be removed 
entirely. According to the commenters, removal of the crankshaft is 
sometimes necessary to access components, but this should not 
constitute replacement. Commenters said that the removal of the serial 
number from the engine should not necessitate the need to comply with 
new engine standards. Commenters indicated that the serial number could 
be inadvertently knocked off during transportation or use, and asked 
that it also not be included as a criterion in the final rule.
    Response: As with the EPA's proposed definition of ``reconstruct,'' 
the proposal to add a definition for the ``date of manufacture'' led to 
a significant concern with affected stakeholders as reflected in this 
comment summary. Commenters were generally not opposed to having a 
definition for the ``date of manufacture,'' but were against some of 
the criteria used in the proposed definition.
    Based on the comments related to removal of the crankshaft, the EPA 
agrees that including the engine crankshaft language in the definition 
of ``date of manufacture'' would not be appropriate. The EPA does not 
wish to trigger more stringent standards for engines that are simply 
undergoing regular maintenance. Notably, solely removing the engine 
crankshaft is not an indication that a substantial amount of work has 
been conducted on the engine to the extent that it should have to meet 
to more stringent emission standards. Consequently, the EPA is not 
including the crankshaft criteria in the definition

[[Page 37965]]

of ``date of manufacture'' in the final rule.
    Regarding comments opposing the inclusion of the serial number in 
the definition of ``date of manufacture,'' the EPA agrees that it would 
be appropriate to exclude that specific criterion in the final rule. 
The EPA does not wish to require more stringent standards for 
reconstructed engines solely due to the possibility that in some cases, 
the serial number might not be available, for instance, it may have 
been knocked off during transportation, use or maintenance, or if the 
engine was acquired and it did not have a tag. The EPA is not 
interested in penalizing affected sources, where information simply is 
not available or missing based on a technicality, by subjecting them to 
more stringent standards. Importantly, the lack of the engine serial 
number is not an indicator that the engine has undergone significant 
modification to the point where it should be subject to more stringent 
standards. Therefore, in the final rule, the EPA has not included the 
serial number criteria in the definition of ``date of manufacture.''
    The EPA believes that finalizing a cost threshold of 75 percent of 
the cost of a new facility in the definition of ``date of manufacture'' 
is appropriate. Based on the comments received, it appears that the 
majority of the issues surrounding the date of manufacture concept were 
related to the crankshaft being included in the definition. Since the 
EPA is not including the engine crankshaft as a determining factor for 
assigning an engine a new date of manufacture, the EPA believes that 
most of the issues brought up by commenters would be resolved.
    Comment: One commenter thought that the definition of ``installed'' 
in sections 60.4248 and 60.4219 of the proposed NSPS amendments should 
be modified. The commenter indicated that part of the definition is 
appropriate, i.e., in terms of having the engine ``placed and secured 
at a location where it is intended to operate'' for defining 
``installed.'' However, the commenter did not agree with the rest of 
the definition as that states ``* * * the piping and wiring for 
exhaust, fuel, controls, etc., is installed and all connections are 
made; and the engine is capable of being started.'' The commenter 
recommended that the final definition read as follows: ``Installed 
means the engine is placed and secured at the location where it is 
intended to be operated.'' According to the commenter, because 
stationary engines are often part of a larger facility, the engines may 
be placed at the location in advance of completing the rest of the 
facility and this could be significantly prior to utilities being 
completed (including local permits and building inspections). In the 
commenter's opinion, creating the foundation and placing the engine at 
the location indicates major commitment by the owner, and the commenter 
did not believe that it is necessary to finalize the remaining 
connections in order to demonstrate the owner's intent, and such 
connections are typically more related to the larger construction 
project than the engine itself.
    Response: The EPA agrees with the commenter's recommendations 
regarding the definition of ``installed.'' The EPA agrees that 
installation should be defined as the engine has been placed and 
secured where it is intended to be operated, and that the engine does 
not have to be capable of being started before it can be considered 
installed, since the final piping and wiring may not be completed until 
well after the engine is secured in its permanent location.

VI. Summary of Environmental, Energy and Economic Impacts

A. What are the air quality impacts?

    The final rule would reduce NOX emissions from 
stationary CI ICE with a displacement between 10 and 30 l/cyl by an 
estimated 300 tons per year (tpy), PM emissions by about 8 tpy, and HC 
emissions by about 4 tpy, in the year 2018. The EPA estimated emissions 
reductions for the year 2018 because the year 2018 is the first year 
the emission standards would be fully implemented for stationary CI 
engines between 10 and 30 l/cyl. In the year 2030, the final rule would 
reduce NOX emissions from stationary CI ICE between 10 and 
30 l/cyl by an estimated 1,100 tpy, PM emissions by about 38 tpy, and 
HC emissions by about 18 tpy. Emissions reductions were estimated for 
the year 2030 to provide an estimate of what the reductions would be 
once there has been substantial turnover in the engine fleet. The EPA 
expects very few stationary CI ICE with a displacement of 30 l/cyl or 
more to be installed per year, and no emissions reductions have been 
estimated for these engines.

B. What are the cost impacts?

    The total costs of the final rule are based on the cost associated 
with purchasing and installing controls on non-emergency stationary CI 
ICE with a displacement between 10 and 30 l/cyl. The costs of 
aftertreatment were based on information developed for CI marine 
engines. Further information on how the EPA estimated the total costs 
of the final rule can be found in a memorandum included in the docket 
(Docket ID. No. EPA-HQ-OAR-2010-0295).
    The total national capital cost for the final rule is estimated to 
be approximately $236,000 in the year 2018, with a total national 
annual cost of $142,000 in the year 2018. The year 2018 is the first 
year the emission standards would be fully implemented for stationary 
CI engines between 10 and 30 l/cyl. The total national capital cost for 
the final rule in the year 2030 is $235,000, with a total national 
annual cost of $711,000. All of these costs are in 2009 dollars.

C. What are the economic impacts?

    The EPA expects that there will be less than a 0.001 percent 
increase in price and a similar decrease in product demand associated 
with this final rule for producers and consumers in 2018. For more 
information, please refer to the economic impact analysis for this 
rulemaking in the docket.

D. What are the non-air health, environmental and energy impacts?

    The EPA does not anticipate any significant non-air health, 
environmental or energy impacts as a result of this final rule.

VII. Statutory and Executive Order Reviews

A. Executive Order 12866: Regulatory Planning and Review and Executive 
Order 13563: Improving Regulation and Regulatory 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 Executive Orders 12866 and 13563 
(76 FR 3821, January 21, 2011).

B. Paperwork Reduction Act

    This action does not impose any new information collection burden. 
This action does not impose an information collection burden because 
the Agency is not requiring any additional recordkeeping, reporting, 
notification or other requirements in this final rule. The changes 
being finalized in this action do not affect information collection, 
but include revisions to emission standards and other minor issues. 
However, the Office of Management and Budget (OMB) has previously 
approved the information collection requirements contained in the 
existing regulations (40 CFR part 60 subpart A) under the provisions of 
the Paperwork Reduction Act, 44 U.S.C. 3501 et seq. and has assigned 
OMB control number 2060-0590. The OMB

[[Page 37966]]

control numbers for the EPA's regulations in 40 CFR are listed in 40 
CFR part 9.

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 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 this final rule on small 
entities, small entity is defined as: (1) A small business as defined 
by the Small Business Administration's (SBA) 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.
    For the electric power generation industry (NAICS 2211), the small 
business size standard is an ultimate parent entity defined as having a 
total electric output of 4 million megawatt-hours in the previous 
fiscal year. The specific SBA size standard is identified for each 
affected industry within the Economic Impact Analysis for the final 
rule. In this case, the EPA presumes the affected engines will all be 
located in the electric power generation industry.
    After considering the economic impacts of this final rule on small 
entities, I certify that this action will not have a significant 
economic impact on a substantial number of small entities (SISNOSE). 
The EPA estimates that only three firms are expected to incur costs 
associated with this final rule, and only one of these firms is a small 
entity. This small entity is expected to have annualized costs that are 
less than 0.001 percent of its sales. Hence, the EPA concludes that 
there is no SISNOSE for this rule.
    Although this 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. When 
developing the revised standards, EPA conducted several meetings with 
industry trade associations to discuss regulatory options and the 
corresponding burden on industry, such as recordkeeping and reporting. 
The final rule requires the minimum level of testing, monitoring, 
recordkeeping, and reporting to affected stationary ICE sources 
necessary to ensure compliance. For more information on the small 
entity impacts associated with the final rule, please refer to the 
Economic Impact Analysis in the public docket at http://
www.regulations.gov. (Docket ID No. EPA-HQ-OAR-2010-0295).

D. Unfunded Mandates Reform Act of 1995

    This rule 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. 
Only minimal changes are being finalized by the Agency in this action 
and where compliance costs are incurred, only a nominal number of 
stationary CI engines will experience a compliance cost expense. Thus, 
this rule is not subject to the requirements of sections 202 or 205 of 
the Unfunded Mandates Reform Act (UMRA).
    This 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. The changes being 
finalized in this action by the Agency are minimal and mostly affect 
stationary CI engine manufacturers and will not affect small 
governments.

E. Executive Order 13132: Federalism

    This action 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 action 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 action.

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

    This final 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 final rule.

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

    The EPA interprets Executive Order 13045 (62 FR 19885, April 23, 
1997) as applying only to those regulatory actions that are based on 
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 and Advancement Act

    Section 12(d) of the National Technology Transfer and Advancement 
Act of 1995 (``NTTAA''), Public Law 104-113, 12(d) (15 U.S.C. 272 note) 
directs the 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 the EPA to provide 
Congress, through OMB, explanations when the Agency decides not to use 
available and applicable voluntary consensus standards.
    This action does not involve technical standards. Therefore, the 
EPA did not consider the use of any voluntary consensus standards.

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 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,

[[Page 37967]]

policies, and activities on minority populations and low-income 
populations in the United States.
    The EPA has determined that this final rule will not have 
disproportionately high and adverse human health or environmental 
effects on minority or low-income populations because it does not 
affect the level of protection provided to human health or the 
environment. The changes the Agency is finalizing in this action will 
reduce emissions from certain stationary CI engines, which were 
previously not controlled as stringently as now. Other changes the 
Agency is finalizing have minimal effect on emissions.

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. The EPA will submit a report containing this final 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 this final rule in the Federal Register. A major rule 
cannot take effect until 60 days after it is published in the Federal 
Register. This action is not a ``major rule'' as defined by 5 U.S.C. 
804(2). This final rule will be effective on August 29, 2011.

Sec.  60.4211  What are my compliance requirements if I am an owner or 
operator of a stationary CI internal combustion engine?

    (a) If you are an owner or operator and must comply with the 
emission standards specified in this subpart, you must do all of the 
following, except as permitted under paragraph (g) of this section:
    (1) Operate and maintain the stationary CI internal combustion 
engine and control device according to the manufacturer's emission-
related written instructions;
    (2) Change only those emission-related settings that are permitted 
by the manufacturer; and
    (3) Meet the requirements of 40 CFR parts 89, 94 and/or 1068, as 
they apply to you.
* * * * *
    (c) * * * The engine must be installed and configured according to 
the manufacturer's emission-related specifications, except as permitted 
in paragraph (g) of this section.
* * * * *
    (e) If you are an owner or operator of a modified or reconstructed 
stationary CI internal combustion engine and must comply with the 
emission standards specified in Sec.  60.4204(e) or Sec.  60.4205(f), 
you must demonstrate compliance according to one of the methods 
specified in paragraphs (e)(1) or (2) of this section.
    (1) Purchasing, or otherwise owning or operating, an engine 
certified to the emission standards in Sec.  60.4204(e) or Sec.  
60.4205(f), as applicable.
    (2) Conducting a performance test to demonstrate initial compliance 
with the emission standards according to the requirements specified in 
Sec.  60.4212 or Sec.  60.4213, as appropriate. The test must be 
conducted within 60 days after the engine commences operation after the 
modification or reconstruction.
    (f) Emergency stationary ICE may be operated 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 ICE beyond 100 hours per year. Emergency stationary ICE 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 non-
emergency 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.
    (g) If you do not install, configure, operate, and maintain your 
engine and control device according to the manufacturer's emission-
related written instructions, or you change emission-related settings 
in a way that is not permitted by the manufacturer, you must 
demonstrate compliance as follows:
    (1) If you are an owner or operator of a stationary CI internal 
combustion engine with maximum engine power less than 100 HP, you must 
keep a maintenance plan and records of conducted maintenance to 
demonstrate compliance and must, to the extent practicable, maintain 
and operate the engine in a manner consistent with good air pollution 
control practice for minimizing emissions. In addition, if you do not 
install and configure the engine and control device according to the 
manufacturer's emission-related written instructions, or you change the 
emission-related settings in a way that is not permitted by the 
manufacturer, you must conduct an initial performance test to 
demonstrate compliance with the applicable emission standards within 1 
year of such action.
    (2) If you are an owner or operator of a stationary CI internal 
combustion engine greater than or equal to 100 HP and less than or 
equal to 500 HP, you must keep a maintenance plan and records of 
conducted maintenance and must, to the extent practicable, maintain

[[Page 37971]]

and operate the engine in a manner consistent with good air pollution 
control practice for minimizing emissions. In addition, you must 
conduct an initial performance test to demonstrate compliance with the 
applicable emission standards within 1 year of startup, or within 1 
year after an engine and control device is no longer installed, 
configured, operated, and maintained in accordance with the 
manufacturer's emission-related written instructions, or within 1 year 
after you change emission-related settings in a way that is not 
permitted by the manufacturer.
    (3) If you are an owner or operator of a stationary CI internal 
combustion engine greater than 500 HP, you must keep a maintenance plan 
and records of conducted maintenance and must, to the extent 
practicable, maintain and operate the engine in a manner consistent 
with good air pollution control practice for minimizing emissions. In 
addition, you must conduct an initial performance test to demonstrate 
compliance with the applicable emission standards within 1 year of 
startup, or within 1 year after an engine and control device is no

(e) Revising the definition of ``Stationary internal combustion 
engine''; and
0
(f) Removing the definition of ``Useful life'' to read as follows.


Sec.  60.4219  What definitions apply to this subpart?

* * * * *
    Certified emissions life means the period during which the engine 
is designed to properly function in terms of reliability and fuel 
consumption, without being remanufactured, specified as a number of 
hours of operation or calendar years, whichever comes first. The values 
for certified emissions life for stationary CI ICE with a displacement 
of less than 10 liters per cylinder are given in 40 CFR 1039.101(g). 
The values for certified emissions life for stationary CI ICE with a 
displacement of greater than or equal to 10 liters per cylinder and 
less than 30 liters per cylinder are given in 40 CFR 94.9(a).
* * * * *
    Date of manufacture means one of the following things:
    (1) For freshly manufactured engines and modified engines, date of 
manufacture means the date the engine is originally produced.
    (2) For reconstructed engines, date of manufacture means the date 
the engine was originally produced, except as specified in paragraph 
(3) of this definition.
    (3) Reconstructed engines are assigned a new date of manufacture if 
the fixed capital cost of the new and refurbished components exceeds 75 
percent of the fixed capital cost of a comparable entirely new 
facility. An engine that is produced from a previously used engine 
block does not retain the date of manufacture of the engine in which 
the engine block was previously used if the engine is produced using 
all new components except for the engine block. In these cases, the 
date of manufacture is the date of reconstruction or the date the new 
engine is produced.
* * * * *
    Freshly manufactured engine means an engine that has not been 
placed into service. An engine becomes freshly manufactured when it is 
originally produced.
* * * * *
    Installed means the engine is placed and secured at the location 
where it is intended to be operated.
* * * * *
    Model year means the calendar year in which an engine is 
manufactured (see ``date of manufacture''), except as follows:
    (1) Model year means the annual new model production period of the 
engine manufacturer in which an engine is manufactured (see ``date of 
manufacture''), if the annual new model production period is different 
than the calendar year and includes January 1 of the calendar year for 
which the model year is named. It may not begin before January 2 of the 
previous calendar year and it must end by December 31 of the named 
calendar year.
    (2) For an engine that is converted to a stationary engine after 
being placed into service as a nonroad or other non-stationary engine, 
model year means the calendar year or new model production period in 
which the engine was manufactured (see ``date of manufacture'').
* * * * *
    Stationary internal combustion engine means any internal combustion 
engine, except combustion turbines, that converts heat energy into 
mechanical work and is not mobile. Stationary ICE differ from mobile 
ICE in that a stationary internal combustion engine is not a nonroad 
engine as defined at 40 CFR 1068.30 (excluding paragraph (2)(ii) of 
that definition), and is not used to propel a motor vehicle, aircraft, 
or a vehicle used solely for competition. Stationary ICE include 
reciprocating ICE, rotary ICE, and other ICE, except combustion 
turbines.

Sec.  60.4248  What definitions apply to this subpart?

* * * * *
    Certified emissions life means the period during which the engine 
is designed to properly function in terms of reliability and fuel 
consumption, without being remanufactured, specified as a number of 
hours of operation or calendar years, whichever comes first. The values 
for certified emissions life for stationary SI ICE with a maximum 
engine power less than or equal to 19 KW (25 HP) are given in 40 CFR 
90.105, 40 CFR 1054.107, and 40 CFR 1060.101, as appropriate. The 
values for certified emissions life for stationary SI ICE with a 
maximum engine power greater than 19 KW (25 HP) certified to 40 CFR 
part 1048 are given in 40 CFR 1048.101(g). The certified emissions life 
for stationary SI ICE with a maximum engine power greater than 75 KW 
(100 HP) certified under the voluntary manufacturer certification 
program of this subpart is 5,000 hours or 7 years, whichever comes 
first. You may request in your application for certification that we 
approve a shorter certified emissions life for an engine family. We may 
approve a shorter certified emissions life, in hours of engine 
operation but not in years, if we determine that these engines will 
rarely operate longer than the shorter certified emissions life. If 
engines identical to those in the engine family have already been 
produced and are in use, your demonstration must include documentation 
from such in-use engines. In other cases, your demonstration must 
include an engineering analysis of information equivalent to such in-
use data, such as data from research engines or similar engine models 
that are already in production. Your demonstration must also include 
any overhaul interval that you recommend, any mechanical warranty that 
you offer for the engine or its components, and any relevant customer 
design specifications. Your demonstration may include any other 
relevant information. The certified emissions life value may not be 
shorter than any of the following:
    (i) 1,000 hours of operation.
    (ii) Your recommended overhaul interval.
    (iii) Your mechanical warranty for the engine.
* * * * *

[[Page 37975]]

    Date of manufacture means one of the following things:
    (1) For freshly manufactured engines and modified engines, date of 
manufacture means the date the engine is originally produced.
    (2) For reconstructed engines, date of manufacture means the date 
the engine was originally produced, except as specified in paragraph 
(3) of this definition.
    (3) Reconstructed engines are assigned a new date of manufacture if 
the fixed capital cost of the new and refurbished components exceeds 75 
percent of the fixed capital cost of a comparable entirely new 
facility. An engine that is produced from a previously used engine 
block does not retain the date of manufacture of the engine in which 
the engine block was previously used if the engine is produced using 
all new components except for the engine block. In these cases, the 
date of manufacture is the date of reconstruction or the date the new 
engine is produced.
* * * * *
    Freshly manufactured engine means an engine that has not been 
placed into service. An engine becomes freshly manufactured when it is 
originally produced.
* * * * *
    Installed means the engine is placed and secured at the location 
where it is intended to be operated.
* * * * *
    Liquefied petroleum gas means any liquefied hydrocarbon gas 
obtained as a by-product in petroleum refining or natural gas 
production.
    Model year means the calendar year in which an engine is 
manufactured (see ``date of manufacture''), except as follows:
    (1) Model year means the annual new model production period of the 
engine manufacturer in which an engine is manufactured (see ``date of 
manufacture''), if the annual new model production period is different 
than the calendar year and includes January 1 of the calendar year for 
which the model year is named. It may not begin before January 2 of the 
previous calendar year and it must end by December 31 of the named 
calendar year.
    (2) For an engine that is converted to a stationary engine after 
being placed into service as a nonroad or other non-stationary engine, 
model year means the calendar year or new model production period in 
which the engine was manufactured (see ``date of manufacture'').
* * * * *
    Stationary internal combustion engine means any internal combustion 
engine, except combustion turbines, that converts heat energy into 
mechanical work and is not mobile. Stationary ICE differ from mobile 
ICE in that a stationary internal combustion engine is not a nonroad 
engine as defined at 40 CFR 1068.30 (excluding paragraph (2)(ii) of 
that definition), and is not used to propel a motor vehicle, aircraft, 
or a vehicle used solely for competition. Stationary ICE include 
reciprocating ICE, rotary ICE, and other ICE, except combustion 
turbines.
    Stationary internal combustion engine test cell/stand means an 
engine test cell/stand, as defined in 40 CFR part 63, subpart PPPPP, 
that tests stationary ICE.
