EXPLANATION
The Code of Federal Regulations is a codification of the general and
permanent rules published in the Federal Register by the Executive
departments and agencies of the Federal Government. The Code is divided
into 50 titles which represent broad areas subject to Federal
regulation. Each title is divided into chapters which usually bear the
name of the issuing agency. Each chapter is further subdivided into
parts covering specific regulatory areas.
Each volume of the Code is revised at least once each calendar year
and issued on a quarterly basis approximately as follows:
Title 1 through Title 16.................................as of January 1
Title 17 through Title 27..................................as of April 1
Title 28 through Title 41...................................as of July 1
Title 42 through Title 50................................as of October 1
The appropriate revision date is printed on the cover of each
volume.
LEGAL STATUS
The contents of the Federal Register are required to be judicially
noticed (44 U.S.C. 1507). The Code of Federal Regulations is prima facie
evidence of the text of the original documents (44 U.S.C. 1510).
HOW TO USE THE CODE OF FEDERAL REGULATIONS
The Code of Federal Regulations is kept up to date by the individual
issues of the Federal Register. These two publications must be used
together to determine the latest version of any given rule.
To determine whether a Code volume has been amended since its
revision date (in this case, July 1, 2007), consult the ``List of CFR
Sections Affected (LSA),'' which is issued monthly, and the ``Cumulative
List of Parts Affected,'' which appears in the Reader Aids section of
the daily Federal Register. These two lists will identify the Federal
Register page number of the latest amendment of any given rule.
EFFECTIVE AND EXPIRATION DATES
Each volume of the Code contains amendments published in the Federal
Register since the last revision of that volume of the Code. Source
citations for the regulations are referred to by volume number and page
number of the Federal Register and date of publication. Publication
dates and effective dates are usually not the same and care must be
exercised by the user in determining the actual effective date. In
instances where the effective date is beyond the cut-off date for the
Code a note has been inserted to reflect the future effective date. In
those instances where a regulation published in the Federal Register
states a date certain for expiration, an appropriate note will be
inserted following the text.
OMB CONTROL NUMBERS
The Paperwork Reduction Act of 1980 (Pub. L. 96-511) requires
Federal agencies to display an OMB control number with their information
collection request.
[[Page vi]]
Many agencies have begun publishing numerous OMB control numbers as
amendments to existing regulations in the CFR. These OMB numbers are
placed as close as possible to the applicable recordkeeping or reporting
requirements.
OBSOLETE PROVISIONS
Provisions that become obsolete before the revision date stated on
the cover of each volume are not carried. Code users may find the text
of provisions in effect on a given date in the past by using the
appropriate numerical list of sections affected. For the period before
January 1, 2001, consult either the List of CFR Sections Affected, 1949-
1963, 1964-1972, 1973-1985, or 1986-2000, published in 11 separate
volumes. For the period beginning January 1, 2001, a ``List of CFR
Sections Affected'' is published at the end of each CFR volume.
INCORPORATION BY REFERENCE
What is incorporation by reference? Incorporation by reference was
established by statute and allows Federal agencies to meet the
requirement to publish regulations in the Federal Register by referring
to materials already published elsewhere. For an incorporation to be
valid, the Director of the Federal Register must approve it. The legal
effect of incorporation by reference is that the material is treated as
if it were published in full in the Federal Register (5 U.S.C. 552(a)).
This material, like any other properly issued regulation, has the force
of law.
What is a proper incorporation by reference? The Director of the
Federal Register will approve an incorporation by reference only when
the requirements of 1 CFR part 51 are met. Some of the elements on which
approval is based are:
(a) The incorporation will substantially reduce the volume of
material published in the Federal Register.
(b) The matter incorporated is in fact available to the extent
necessary to afford fairness and uniformity in the administrative
process.
(c) The incorporating document is drafted and submitted for
publication in accordance with 1 CFR part 51.
Properly approved incorporations by reference in this volume are
listed in the Finding Aids at the end of this volume.
What if the material incorporated by reference cannot be found? If
you have any problem locating or obtaining a copy of material listed in
the Finding Aids of this volume as an approved incorporation by
reference, please contact the agency that issued the regulation
containing that incorporation. If, after contacting the agency, you find
the material is not available, please notify the Director of the Federal
Register, National Archives and Records Administration, Washington DC
20408, or call 202-741-6010.
CFR INDEXES AND TABULAR GUIDES
A subject index to the Code of Federal Regulations is contained in a
separate volume, revised annually as of January 1, entitled CFR Index
and Finding Aids. This volume contains the Parallel Table of Statutory
Authorities and Agency Rules (Table I). A list of CFR titles, chapters,
and parts and an alphabetical list of agencies publishing in the CFR are
also included in this volume.
An index to the text of ``Title 3--The President'' is carried within
that volume.
The Federal Register Index is issued monthly in cumulative form.
This index is based on a consolidation of the ``Contents'' entries in
the daily Federal Register.
A List of CFR Sections Affected (LSA) is published monthly, keyed to
the revision dates of the 50 CFR titles.

Sec. 87.3 General requirements.
(a) This part provides for the approval or acceptance by the
Administrator or the Secretary of testing and sampling methods,
analytical, techniques, and related equipment not identical to those
specified in this part. Before either approves or accepts any such
alternate, equivalent, or otherwise nonidentical procedures or
equipment, the Administrator or the Secretary shall consult with the
other in determining whether or not the action requires rulemaking under
sections 231 and 232 of the Clean Air Act, as amended, consistent with
the Administrator's and the Secretary's responsibilities under sections
231 and 232 of the Act. (42 U.S.C. 7571, 7572).
(b) Under section 232 of the Act, the Secretary issues regulations
to insure compliance with this part.
(c) With respect to aircraft of foreign registry, these regulations
shall apply in a manner consistent with any obligation assumed by the
United States in any treaty, convention or agreement between the United
States and any foreign country or foreign countries.
Sec. 87.4 [Reserved]
Sec. 87.5 Special test procedures.
The Administrator or the Secretary may, upon written application by
a manufacturer or operator of aircraft or aircraft engines, approve test
procedures for any aircraft or aircraft engine that is not susceptible
to satisfactory testing by the procedures set forth herein. Prior to
taking action on any such application, the Administrator or the
Secretary shall consult with the other.
Sec. 87.6 Aircraft safety.
The provisions of this part will be revised if at any time the
Secretary determines that an emission standard cannot be met within the
specified time without creating a safety hazard.
Sec. 87.7 Exemptions.
(a) Exemptions based on flights for short durations at infrequent
intervals. The emission standards of this part do not apply to engines
which power aircraft operated in the United States for short durations
at infrequent intervals. Such operations are limited to:
(1) Flights of an aircraft for the purpose of export to a foreign
country, including any flights essential to demonstrate the integrity of
an aircraft prior to its flight to a point outside the United States.
(2) Flights to a base where repairs, alterations or maintenance are
to be performed, or to a point of storage, and flights for the purpose
of returning an aircraft to service.
(3) Official visits by representatives of foreign governments.
(4) Other flights the Secretary determines, after consultation with
the Administrator, to be for short durations at infrequent intervals. A
request for such a determination shall be made before the flight takes
place.
(b) Exemptions for very low production models. The emissions
standards of this part do not apply to engines of very low total
production after the date of applicability. For the purpose of this
part, ``very low production'' is limited to a maximum total production
for United States civil aviation applications of no more than 200 units
covered by the same type certificate after January 1, 1984.
(c) Exemptions for New Engines in Other Categories. The emissions
standards of this part do not apply to engines for which the Secretary
determines, with the concurrence of the Administrator, that application
of any standard under Sec. 87.21 is not justified, based upon
consideration of:
(1) Adverse economic impact on the manufacturer.
(2) Adverse economic impact on the aircraft and airline industries
at large.
(3) Equity in administering the standards among all economically
competing parties.
(4) Public health and welfare effects.
(5) Other factors which the Secretary, after consultation with the
Administrator, may deem relevant to the case in question.
(d) Time Limited Exemptions for In Use Engines. The emissions
standards of this part do not apply to aircraft or aircraft engines for
time periods which the Secretary determines, with the concurrence of the
Administrator, that any applicable standard under Sec. 87.11(a),
[[Page 8]]
Sec. 87.31(a), or Sec. 87.31(c), should not be applied based upon
consideration of the following:
(1) Documentation demonstrating that all good faith efforts to
achieve compliance with such standard have been made.
(2) Documentation demonstrating that the inability to comply with
such standard is due to circumstances beyond the control of the owner or
operator of the aircraft.
(3) A plan in which the owner or operator of the aircraft shows that
he will achieve compliance in the shortest time which is feasible.
(4) Applications for a determination that any requirements of Sec.
87.11(a), Sec. 87.31(a) or Sec. 87.31(c) do not apply shall be
submitted in duplicate to the Secretary in accordance with procedures
established by the Secretary.
(e) The Secretary shall publish in the Federal Register the name of
the organization to whom exemptions are granted and the period of such
exemptions.
(f) No state or political subdivision thereof may attempt to enforce
a standard respecting emissions from an aircraft or engine if such
aircraft or engine has been exempted from such standard under this part.

Subpart G_Test Procedures for Engine Exhaust Gaseous Emissions (Aircraft
and Aircraft Gas Turbine Engines)
Sec. 87.60 Introduction.
(a) Except as provided under Sec. 87.5, the procedures described in
this subpart shall be the test program to determine the conformity of
new aircraft gas turbine engines with the applicable standards set forth
in this part.
(b) The test consists of operating the engine at prescribed power
settings on an engine dynamometer (for engines producing primarily shaft
power) or thrust measuring test stand (for engines producing primarily
thrust). The exhaust gases generated during engine operation are sampled
continuously for specific component analysis through the analytical
train.
(c) The exhaust emission test is designed to measure hydrocarbons,
carbon monoxide, carbon dioxide, and oxides of nitrogen concentrations,
and to determine mass emissions through calculations during a simulated
aircraft landing-takeoff cycle (LTO). The LTO cycle is based on time in
mode data during high activity periods at major airports. The test for
propulsion engines consists of at least the following four modes of
engine operation: taxi/idle, takeoff, climbout, and approach. The mass
emission for the modes are combined to yield the reported values.
(d) When an engine is tested for exhaust emissions on an engine
dynamometer or test stand, the complete
[[Page 11]]
engine shall be used with all accessories which might reasonably be
expected to influence emissions to the atmosphere installed and
functioning, if not otherwise prohibited by Sec. 87.62(a)(2). Use of
service air bleed and shaft power extraction to power auxiliary gearbox-
mounted components required to drive aircraft systems is not permitted.
(e) Other gaseous emissions measurement systems may be used if shown
to yield equivalent results and if approved in advance by the
Administrator or the Secretary.

certification as permitted by regulation.
Sales means vehicles that are produced, sold, and distributed (in
accordance with normal business practices and applicable franchise
agreements) in the State of California, including owners of covered
fleets under subpart C of part 86 of this chapter. The manufacturer can
choose at their option from one of the following three methods for
determining sales:
(i) Sales is defined as sales to the ultimate purchaser.
(ii) Sales is defined as vehicle sales by a manufacturer to a
dealer, distributer, fleet operator, broker, or any other entity which
comprises the first point of sale.
(iii) Sales is defined as equivalent to the production of vehicles
for the state of California. This option can be revoked if it is
determined that the production and actual sales numbers do not exhibit a
functional equivalence
[[Page 19]]
per the language of Sec. 86.708-94(b)(1) of this chapter.
Trading means the exchange of credits between manufacturers.
Sec. 88.203-94 Abbreviations.
The abbreviations in subpart A of this part and in 40 CFR part 86
apply to this subpart.
Sec. 88.204-94 Sales requirements for the California Pilot Test Program.
(a) The total annual required minimum sales volume of new clean fuel
vehicles in California for this program shall correspond to Table B204.
(b) (1) When manufacturers of vehicles subject to the regulations of
this section file a report pursuant to 40 CFR 86.085-37(b), such report
shall include the following information: the number of light-duty
vehicles and light-duty trucks sold only in California, and the number
of clean-fuel vehicles sold for the Pilot program beginning with model
year 1996.
(2) For model years 1996 and 1997, manufacturers may exclude heavy
light-duty trucks from the reporting required by this section.
(c) (1) Except as provided in paragraph (d) of this section, each
vehicle manufacturer must sell clean-fuel vehicles in California in an
amount equal to the required annual sales volume calculated in paragraph
(c)(2) of this section.
(2) The required annual clean fuel vehicle sales volume for a given
manufacturer is expressed in the following equation rounded to the
nearest whole number:
[GRAPHIC] [TIFF OMITTED] TR03JA96.003
Where:
RMS = a manufacturer's required sales in a given model year.
MS = the average of a manufacturer's total LDV and light LDT sales in
California three and four model years earlier than year in question (for
MY 1996 and 1997 RMS calculations).
= the average of a manufacturer's total LDV and LDT sales in California
three and four model years earlier than year in question (for MY 1998
and later RMS calculations).
TS = the average of total LDV and light LDT sales in California of all
manufacturers three and four model years earlier than the year in
question (for MY 1996 and 1997 RMS calculations). Sales of manufacturers
which meet the criteria of (d) of this paragraph will not be included.
= the average of total LDV and LDT sales in California of all
manufacturers three and four model years earlier than the year in
question (for MY 1998 and later RMS calculations). Sales of
manufacturers which meet the criteria of (d) of this paragraph will not
be included.
TCPPS = Pilot program annual CFV sales requirement (either 150,000 or
300,000) for the model year in question.
(i) A manufacturer's share of required annual sales for model years
1996 and 1997 will be based on LDV and light LDT sales only. Once the
heavy LDT standards are effective beginning with model year 1998, a
manufacturer's required sales share will be based on all LDV and LDT
sales.
(ii) A manufacturer certifying for the first time in California
shall calculate annual required sales share based on projected
California sales for the model year in question. In the second year, the
manufacturer shall use actual sales from the previous year. In the third
year, the manufacturer will use sales from two model years prior to the
year in question. In the fourth year, the manufacturer will use sales
from three years prior to the year in question. In the fifth year and
subsequent years, the manufacturer will use average sales from three and
four years prior to the year in question.
(d) (1) Small volume manufacturer is defined in the Pilot program as
one whose average annual LDV and LDT sales in California are less than
or equal to 3,000 units during a consecutive three-year period beginning
no earlier than model year 1993.
(i) A manufacturer with less than three consecutive years of sales
in California shall use a single year of sales or, if available, the
average of two years of sales in California to determine whether they
fall at or below the threshold of 3,000 units.
(ii) A manufacturer certifying for the first time in California
shall be considered a small volume manufacturer if their projected
California sales level is at or below 3,000 units for a given year. Once
the manufacturer has actual sales data for one year, this actual sales
[[Page 20]]
data shall be used to determine whether the manufacturer qualifies as a
small volume manufacturer.
(iii) A manufacturer which does not qualify as a small volume
manufacturer in model year 1996 but whose average annual LDV and LDT
sales fall to or below the 3,000 unit threshold between 1996 and 2001
shall be treated as a small volume manufacturer and shall be subject to
requirements for small volume manufacturers as specified in paragraph
(d)(2) of this section beginning with the next model year.
(2) A manufacturer which qualifies as a small volume manufacturer
prior to model year 2001 is not required to comply with the sales
requirements of this section until model year 2001.

Sec. 88.205-94 California Pilot Test Program Credits Program.
(a) General. (1) The Administrator shall administer this credit
program to enable vehicle manufacturers who are required to participate
in the California Pilot Test Program to meet the clean-fuel vehicle
sales requirements through the use of credits. Participation in this
credit program is voluntary.
(2) All credit-generating vehicles must meet the applicable emission
standards and other requirements contained in subpart A of this part.
(b) Credit generation. (1) Credits may be generated by any of the
following means:
(i) Sale of qualifying clean-fuel vehicles earlier than required.
Manufacturers may earn these credits starting with the 1992 model year,
contingent upon the requirements of paragraph (g) of this section.
(ii) Sale of a greater number of qualifying clean-fuel vehicles than
required.
(iii) Sale of qualifying clean-fuel vehicles that meet more
stringent emission standards than those required.
(2) For light-duty vehicles and light-duty trucks, credit values
shall be determined in accordance with the following:
(i) For model-years through 2000, credit values shall be determined
in accordance with table B-1 of this subpart.
(ii) For the 2001 and subsequent model-years, credit values shall be
determined according to table B-2 of this subpart. The sale of light-
duty vehicles classified as Transitional Low-Emission Vehicles shall not
receive credits starting in model year 2001.
(iii) For the calculation of credits for the sale of more clean-fuel
vehicles than required, the manufacturer shall designate which sold
vehicles count toward compliance with the sales requirement. The
remaining balance of vehicles will be considered as sold beyond the
sales requirement for credit calculations.
(3) Vehicles greater than 8500 lbs gvwr may not generate credits.
(c) Credit use. (1) All credits generated in accordance with these
provisions may be freely averaged, traded, or banked for later use.
Credits may not be used to remedy any nonconformity determined by
enforcement testing.
(2) There is one averaging and trading group containing all light-
duty vehicles and light-duty trucks.
(3) A vehicle manufacturer desiring to demonstrate full or partial
compliance with the sales requirements by the redemption of credits,
shall surrender sufficient credits, as established in this paragraph
(c). In lieu of selling a clean-fuel vehicle, a manufacturer shall
surrender credits equal to the credit value for the corresponding
vehicle class and model year found in table B-1.3 or table B-2.3 of this
subpart.
(d) Participation in the credit program. (1) During certification,
the manufacturer shall calculate the projected credits, if any, based on
required sales projections.
(2) Based on information from paragraph (d)(1) of this section, each
manufacturer's certification application under this section must
demonstrate:
[[Page 21]]
(i) That at the end of the model-year production, there is a net
vehicle credit balance of zero or more with any credits obtained from
averaging, trading, or banking.
(ii) It is recommended but not required that the source of the
credits to be used to comply with the minimum sales requirements be
stated. All such reports should include all credits involved in
averaging, trading, or banking.
(3) During the model year, manufacturers must:
(i) Monitor projected versus actual production to be certain that
compliance with the sales requirement is achieved at the end of the
model year.
(ii) Provide the end of model year reports required under this
subpart.
(iii) Maintain the records required under this subpart.
(4) Projected credits based on information supplied in the
certification application may be used to obtain a certificate of
conformity. However, any such credits may be revoked based on review of
end-of-model year reports, follow-up audits, and any other verification
steps deemed appropriate by the Administrator.
(5) Compliance under averaging, banking, and trading will be
determined at the end of the model year.
(6) If EPA or the manufacturer determines that a reporting error
occurred on an end-of-year report previously submitted to EPA under this
section, the manufacturer's credits and credit calculations will be
recalculated.
(i) If EPA review of a manufacturer's end-of-year report indicates
an inadvertent credit shortfall, the manufacturer will be permitted to
purchase the necessary credits to bring the credit balance to zero.
(ii) If within 90 days of receipt of the manufacturer's end-of-year
report, EPA review determines a reporting error in the manufacturer's
favor (i.e., resulting in a positive credit balance) or if the
manufacturer discovers such an error within 90 days of EPA receipt of
the end-of-year report, the credits will be restored for use by the
manufacturer.
(e) Averaging. Averaging will only be allowed between clean-fuel
vehicles under 8500 lbs gvwr.
(f) Banking--(1) Credit deposits. (i) Under this program, credits
can be banked starting in the 1992 model year.
(ii) A manufacturer may bank credits only after the end of the model
year and after EPA has reviewed its end-of-year report. During the model
year and before submittal of the end-of-year report, credits originally
designated in the certification process for banking will be considered
reserved and may be redesignated for trading or averaging.
(2) Credit withdraws. (i) After being generated, banked/reserved
credits shall be available for use and shall maintain their original
value for an infinite period of time.
(ii) A manufacturer withdrawing banked credits shall indicate so
during certification and in its credit reports.
(3) Banked credits may be used in averaging, trading, or in any
combination thereof, during the certification period. Credits declared
for banking from the previous model year but unreviewed by EPA may also
be used. However, they may be revoked at a later time following EPA
review of the end-of-year report or any subsequent audit actions.
(g) Early credits. Beginning in model year 1992 appropriate credits,
as determined from the given credit table, will be given for the sale of
vehicles certified to the clean-fuel vehicle standards for TLEVs, LEVs,
ULEVs, and ZEVs, where appropriate. For LDVs and light LDTs (<6000 lbs
GVWR), early credits can be earned from model year 1992 to the beginning
of the Pilot Program sales requirements in 1996. For heavy LDTs
(6000 lbs GVWR), early credits can be earned from model years
1992 through 1997. The actual calculation of early credits shall not
begin until model year 1996.

(a) A state may opt into the Pilot program if it contains all or
part of an ozone nonattainment area classified as serious, severe, or
extreme under subpart D of Title I.
(b) A state may opt into the program by submitting SIP revisions
that meet the requirements of this section.
[[Page 22]]
(c) For a state that chooses to opt in, SIP provisions can not take
effect until one year after the state has provided notice to of such
provisions to motor vehicle manufacturers and fuel suppliers.
(d) A state that chooses to opt into the program can not require a
sales or production mandate for CFVs or clean alternative fuels. States
may not subject fuel or vehicle suppliers to penalties or sanctions for
failing to produce or sell CFVs or clean alternative fuels.
(e) (1) A state's SIP may include incentives for the sale or use in
such state of CFVs required in California by the Clean Fuel Fleet
Program, and the use of clean alternative fuels required to be made
available in California by the California Pilot Program.
(2) Incentives may include:
(i) A registration fee on non-CFVs of at least 1 percent of the
total cost of the vehicle. These fees shall be used to:
(A) Provide financial incentives to purchasers of CFVs and vehicle
dealers who sell high volumes or high percentages of CFVs.
(B) Defray administrative costs of the incentive program.
(ii) Exemptions for CFVs from high occupancy vehicle or trip
reduction requirements.
(iii) Preferences for CFVs in the use of existing parking places.

Sec. 88.302-93 Definitions.
The definitions in 40 CFR part 86 of this chapter also apply to this
subpart. The definitions in this section apply to this subpart.
Combination heavy-duty vehicle means a vehicle with a GVWR greater
than 8,500 pounds (3,900 kilograms) which is comprised of a truck-
tractor and one or more pieces of trailered equipment. The truck-tractor
is a self-propelled motor vehicle built on one chassis which encompasses
the engine, passenger compartment, and a means of coupling to a cargo
carrying trailer(s). The truck-tractor itself is not designed to carry
cargo.
Inherently Low-Emission Vehicle means any LDV or LDT conforming to
[[Page 24]]
the applicable Inherently Low-Emission Vehicle standard, or any HDV with
an engine conforming to the applicable Inherently Low-Emission Vehicle
standard. No dual-fuel or flexible-fuel vehicles shall be considered
Inherently Low-Emission Vehicles unless they are certified to the
applicable standard(s) on all fuel types for which they are designed to
operate.
Partially-Covered Fleet pertains to a vehicle fleet in a covered
area which contains both covered fleet vehicles and non-covered fleet
vehicles, i.e., exempt from covered fleet purchase requirements.
Single-unit heavy-duty vehicle means a self-propelled motor vehicle
with a GVWR greater than 8,500 pounds (3,900 kilograms) built on one
chassis which encompasses the engine, passenger compartment, and cargo
carrying function, and not coupled to trailered equipment. All buses,
whether or not they are articulated, are considered single-unit
vehicles.
Sec. 88.302-94 Definitions.
The definitions in Sec. 88.302-93 and 40 CFR part 86 also apply to
this part. All terms used in this part, but not defined in this section
or in Sec. 88.302-93 and 40 CFR part 86 shall have the meaning assigned
to them in the Clean Air Act.
Can be centrally fueled means the sum of those vehicles that are
centrally fueled and those vehicles that are capable of being centrally
fueled.
(1) Capable of being centrally fueled means a fleet, or that part of
a fleet, consisting of vehicles that could be refueled 100 percent of
the time at a location that is owned, operated, or controlled by the

that is, in fact, centrally fueled 100 percent of the time shall be
considered to be centrally fueled for the purpose of this definition.
The fact that one or more vehicles in a fleet is/are not centrally
fueled does not exempt an entire fleet from the program. The fact that a
vehicle is not centrally fueled does not mean it could not be centrally
fueled in accordance with the definition of ``capable of being centrally
fueled.''
(3) Location means any building, structure, facility, or
installation which; is owned or operated by a person, or is under the
control of a person; is located on one or more contiguous properties and
contains or could contain a fueling pump or pumps for the use of the

year, except as follows: Vehicles that were manufactured before the
start of the fleet program for such vehicle's weight class, vehicles
transferred due to the purchase of a company not previously controlled
by the purchaser or due to a consolidation of business operations,
vehicles transferred as part of an employee transfer, or vehicles
transferred for seasonal requirements (i.e., for less than 120 days) are
not considered new. States are permitted to discontinue the use of the
fourth exception for fleet operators who abuse the discretion afforded
them. This definition of new covered fleet vehicle is distinct from the
definition of new vehicle as it applies to manufacturer certification,
including the certification of vehicles to the clean fuel standards.
Owned or operated, leased or otherwise controlled by such person
means either of the following:
(1) Such person holds the beneficial title to such vehicle; or

Sec. 88.303-93 Abbreviations.
The abbreviations in subpart A of this part and in 40 CFR part 86
apply to this subpart. The abbreviations in this section apply to this
subpart.
ILEV--Inherently Low-Emission Vehicle.
Sec. 88.304-94 Clean-fuel Fleet Vehicle Credit Program.
(a) General. (1) The SIP revision shall provide for a CFFV credit
program to enable covered fleet owners/operators to meet the fleet
vehicle purchase requirements of the CAA both by purchasing clean-fuel
vehicles (CFVs) directly and by trading and banking CFFV credits for
vehicle purchases.
(2) All credit-generating vehicles must meet the applicable emission
standards and other requirements contained in 40 CFR part 88, subpart A.
(b) Program administration. (1)(i) Each state in which there is all
or part of a covered area, as defined in CAA section 246(a)(2), shall
promulgate regulations as necessary for implementing this requirement.
(ii) The state shall submit a SIP revision before May 15, 1994 to
the Administrator stipulating the specific mechanism by which the CFFV
program is to be administered and enforced. The credit program shall
commence upon EPA approval of the SIP in accordance with CAA section
246(f)(5).
(2) A fleet owner who purchases/leases a CFFV only to generate CFFV
credit shall be subject to the same requirements of the state's CFFV
program as a covered fleet owner who purchases/leases a CFFV to
demonstrate compliance with covered fleet purchase requirements.
(3) While in the covered area, a dual-fuel/flexible-fuel vehicle
which a fleet owner purchases to comply with covered fleet purchase
requirements must be operated at all times on the fuel(s) on which it
was certified as a CFFV. If the fleet owner receives credit for a dual-
fuel/flexible-fuel vehicle purchase, the vehicle must be operated at the
same emission level for which the vehicle generated CFFV credit.
(c) Credit generation. (1) States shall grant CFFV credits to a
covered fleet owner for any of the following qualifying CFFV purchases:
(i) Purchase of a CFFV during any period subsequent to the approval
of the SIP revision but prior to the effective date for commencement of
a state's CFFV purchase requirement if the purchase meets all other CFFV
requirements applicable to such purchases, including the statutory
requirement to use only the fuel on which the vehicle was certified as a
CFFV;
(ii) Purchase of a greater number of CFFVs than is required under
the SIP revision;
(iii) Purchase of a CFFV which meets more stringent emission
standards than required under the SIP revision; or
(iv) Purchase of a CFFV in an exempt or non-covered vehicle category
by the owner/operator of a covered or partially-covered fleet.
(2) A state may retroactively grant CFFV credit(s) to a fleet owner
for the purchase of a CFFV prior to the approval of the state's SIP
revision if the purchase met all CFFV credit program requirements
applicable to such purchases, including:
(i) The vehicle purchased would have to have been certified to CFFV
emission standards;
(ii) The vehicle purchased would have to have been a dedicated-fuel
vehicle;
(iii) If the vehicle purchased was not a dedicated-fuel vehicle,
then the fleet owner would have to show that the vehicle had been
operated only on the
[[Page 27]]
clean alternative fuel on which the vehicle had been certified as a
CFFV.
(3) For LDVs and LDTs, credit values shall be determined in
accordance with Table C94-1. The state shall use Table C94-1 exclusively
in determining LDV and LDT CFFV credit values. Table C94-1.1 applies to
paragraphs (c)(1) (i), (ii) and (iv) of this section; Table C94-1.2
applies to paragraph (c)(1)(iii) of this section.
(4) In lieu of determining credit values in accordance with Table
C94-1, a state may specify in its SIP revision that Table C94-2 will be
used to determine LDV and LDT CFFV credit values in one or more affected
nonattainment areas. Any state choosing to do so must provide adequate
justification, based on air quality benefits, at the time the SIP
revision is submitted. If the use of Table C94-2 is approved by EPA, the
State shall use Table C94-2 exclusively in determining LDV and LDT CFFV
credit values for vehicles in the subject area or areas. Table C94-2.1
applies to paragraphs (b)(1) (i), (ii) and (iv) of this section; Table
C94-2.2 applies to paragraph (b)(1)(iii) of this section.
(5) In lieu of determining credit values in accordance with Table
C94-1, a state containing a carbon monoxide nonattainment area(s) having
a design value above 16.0 parts per million may specify in its SIP
revision that Table C94-3 will be used to determine LDV and LDT CFFV
credit values in one or more affected nonattainment areas. Any state
choosing to do so must provide adequate justification, based on air
quality benefits, at the time the SIP revision is submitted. If the use
of Table C94-3 is approved by EPA, the state shall use Table C94-3
exclusively in determining LDV and LDT CFFV credit values for vehicles
in the subject area or areas. Table C94-3.1 applies to paragraphs (b)(1)
(i), (ii) and (iv) of this section; Table C94-3.2 applies to paragraph
(b)(1)(iii) of this section.
(6) For HDVs, credit values shall be determined in accordance with
Table C94-4. The state shall use Table C94-4 exclusively in determining
heavy-duty vehicle CFFV credit values. Table C94-4.1 applies to
paragraphs (c)(1) (i), (ii) and (iv) of this section, and Table C94-4.2
applies to paragraph (c)(1)(iii) of this section.
(7) In lieu of determining credit values in accordance with Table
C94-4, a state containing a carbon monoxide nonattainment area(s) having
a design value above 16 parts per million may specify in its SIP
revision that Table C94-5 will be used to determine heavy-duty vehicle
CFFV credit values in one or more affected nonattainment areas. Any
state choosing to do so must provide adequate justification, based on
air quality benefits, at the time the SIP revision is submitted. If the
use of Table C94-5 is approved by EPA, the State shall use Table C94-5
exclusively in determining heavy-duty vehicle CFFV credit values for
vehicles in the subject area or areas. Table C94-5.1 applies to
paragraphs (b)(1) (i), (ii) and (iv) of this section; Table C94-5.2
applies to paragraph (b)(1)(iii) of this section.
(8) Credit values shall be rounded to two decimal places.
(9) Heavy heavy-duty vehicles. (i) States must allow purchase of any
clean-fuel single-unit or combination HDV with a GVWR greater than
26,000 pounds (11,800 kilograms) to generate CFFV credit for the fleet
vehicle purchaser.
(ii) States must exclude from generating CFFV credit the purchase of
any combination HDV with a GVWR greater than 26,000 pounds (11,800
kilograms) which pays all or a portion of its fuel taxes, as evidenced
by fuel tax stickers on the combination HDV, to a state(s) which is not
part of that covered nonattainment area.
(10) Light-duty CFFV credits. Credits generated by the purchase of a
qualifying clean-fuel fleet LDV or a LDT shall be designated at the time
of issuance as light-duty CFFV credits.
(11) Heavy-duty CFFV credits. Credits generated by the purchase of a
qualifying clean-fuel fleet HDV shall be designated at the time of
issuance as heavy-duty CFFV credits. Further, credits generated by the
purchase of a light heavy-duty or a medium heavy-duty qualifying CFFV
shall be designated at the time of issuance as light heavy-duty and
medium heavy-duty CFFV credits, respectively.
[[Page 28]]
(d) Credit use. (1) All credits generated in accordance with these
provisions may be freely traded or banked for later use, subject to the
provisions contained in this subpart, without discount or depreciation
of such credits.
(2) A covered fleet owner or operator desiring to demonstrate full
or partial compliance with covered fleet purchase requirements by the
redemption of credits shall surrender sufficient credits as established
in this paragraph. In lieu of purchasing a CFFV, a fleet owner or
operator shall surrender credits equal to the credit value for the
corresponding vehicle class and credit calculation method used in that
area from either Table C94-1.3, C94-2.3, C94-3.3, C94-4.3, or C94-5.3 of
this subpart.
(3) Credits earned within the boundaries of a covered nonattainment
area may be traded within those boundaries whether or not that area
encompasses parts of more than one state.
(4) Credits issued as a result of CFFV purchase requirements in one
nonattainment area may not be used to demonstrate compliance in another
nonattainment area, even if a state contains more than one covered
nonattainment area.
(5) Credit allocation. (i) Credits generated by the purchase of LDVs
and LDTs of 8,500 pounds (3,900 kilograms) GVWR or less may be used to
demonstrate compliance with covered fleet purchase requirements
applicable to LDVs or LDTs of 8,500 pounds (3,900 kilograms) GVWR or
less.
(ii) Credits generated by the purchase of vehicles of more than
8,500 pounds (3,900 kilograms) GVWR may not be used to demonstrate
compliance with the covered fleet purchase requirements for vehicles
weighing 8,500 pounds (3,900 kilograms) GVWR or less.
(iii) Credits generated by the purchase of vehicles of 8,500 pounds
(3,900 kilograms) GVWR or less may not be used to demonstrate compliance
with requirements for vehicles of more than 8,500 pounds (3,900

purchase of a clean-fuel vehicle under subpart C of this part.
(b) The engine or vehicle must be converted using a conversion
configuration which has been certified according to the provisions of 40
CFR part 86 using applicable emission standards and other provisions
from part 88 for clean-fuel engines and vehicles. The following
requirements will also apply:
[[Page 29]]
(1) If the installation of the certified conversion configuration is
performed by an entity other than aftermarket conversion certifier, the
aftermarket conversion certifier shall submit a list of such installers
to the Administrator. Additional installers must be added to this list
and the revised list submitted to the Administrator within 5 working
days from the time they are authorized to perform conversion
installations by the clean-fuel vehicle aftermarket conversion
certifier.
(2) If the installation of the certified conversion configuration is
performed by an entity other than the certificate holder, the
certificate holder shall provide instructions for installation of the
aftermarket conversion system to installers listed on the certificate,
and ensure that the systems are properly installed.
(3) For the purpose of determining whether certification under the
Small-Volume Manufacturers Certification Program pursuant to the
requirements of 40 CFR 86.094-14 is permitted, the 10,000 sales volume
limit in 40 CFR 86.094-14(b)(1) is waived for a certifier of a clean-
fuel vehicle aftermarket conversion.
(4) Clean-fuel vehicle aftermarket conversion certifiers that are
subject to the post-installation emissions testing requirements in
paragraph (c) of this section and who will satisfy these requirements by
using the two speed idle test procedure detailed in paragraph (c)(2)(ii)
of this section must conduct the following testing at the time of
certification in order to generate the required certification CO
emissions reference values. The certification CO emissions reference
values generated must be submitted to the Administrator at the time of
application for certification.
(i) For dual and flexible fuel vehicles, certification reference
values must be generated for each certification test fuel required for
exhaust emissions testing pursuant to 40 CFR 86.113 or 40 CFR 86.1313.
(ii) For light-duty vehicles and light-duty trucks the test fuels
used during the emissions testing required by paragraph (b)(3) of this
section must comply with the fuel specifications for exhaust emissions
testing found in 40 CFR 86.113. For heavy-duty engines the test fuels
used during the emissions testing required by paragraph (b)(3) of this
section must comply with the fuel specifications for exhaust emissions
testing found in 40 CFR 86.1313.
(iii) Single, consecutive idle mode and high-speed mode segments of
the two speed idle test must be conducted pursuant to the requirements
of 40 CFR 85.2215 and as modified by the provisions of paragraph
(c)(4)(ii)(D) of this section and this paragraph to determine the
required certification CO emission reference values.
(A) The certification CO emission reference value for the idle mode
of the test will be the simple average of all emissions measurements
taken during an idle mode of 90 seconds duration pursuant to the
requirements in 40 CFR 85.2215(a).
(B) The certification CO emission reference value for the high-speed
mode of the test will be the simple average of all emissions
measurements taken during a high-speed mode of 180 seconds duration
pursuant to the requirements in 40 CFR 85.2215(a).
(c) Except as provided in paragraph (c)(1) of this section, each
converted vehicle manufactured by a clean-fuel vehicle aftermarket
conversion certifier with aggregate sales of less than 10,000 converted
vehicles within a given calendar year must satisfy the post-installation
emissions testing requirements of paragraph (c)(2) of this section. If a
vehicle fails to satisfy the emissions testing requirements such vehicle
may not be considered a clean- fuel vehicle until such noncompliance is
rectified and compliance is demonstrated.
(1) A clean-fuel vehicle aftermarket conversion certifier with
estimated sales of 300 or fewer engines and vehicles in a calendar year
and which sells or converts vehicles outside of a non-attainment area
(as classified under subpart D of Title I) which has an inspection and
maintenance program that includes a test of carbon monoxide emissions
may submit a request to the Administrator for an exemption from the
post-installation emission test requirements of paragraph (c) of this
section. If granted, such an exemption would apply to converted vehicles
that
[[Page 30]]
have the conversion installation performed outside of a nonattainment
area which has an inspection and maintenance program that includes a
test of carbon monoxide emissions.
(i) The request for exemption submitted to the Administrator must
include the following:
(A) The estimated number of engines and vehicles that will be
converted in the calendar year.
(B) Sufficient information to demonstrate that complying with the
post-installation emission test requirement represents a severe
financial hardship.
(C) A description of any emission related quality control procedures
used.
(ii) Within 120 days of receipt of the application for exemption,
the Administrator will notify the applicant either that an exemption is
granted or that sufficient cause for an exemption has not been
demonstrated and that all of the clean-fuel vehicle aftermarket
conversion certifier's vehicles are subject to the post-installation
test requirement of paragraph (c)(2) of this section.
(iii) If the clean-fuel vehicle aftermarket conversion certifier
granted an exemption originally estimates that 300 or fewer conversions
would be performed in the calendar year, and then later revises the
estimate to more than 300 for the year, the certifier shall inform the
Administrator of such revision. A post-installation emissions test for
each conversion performed after the estimate is revised is required
pursuant to the requirements of paragraph (c)(2) of this section. The
estimated number of conversions from such a clean-fuel vehicle
aftermarket conversion certifier must be greater than 300 in the
following calendar year.
(2) A clean-fuel vehicle aftermarket conversion certifier with
aggregate sales less than 10,000 converted vehicles within a given
calendar year shall conduct post-installation emissions testing using
either of the following test methods:
(i) The carbon monoxide (CO) emissions of the converted vehicle must
be determined in the manner in which CO emissions are determined
according to the inspection and maintenance requirements applicable in
the area in which the vehicle is converted or is expected to be
operated.
(A) For dual-fuel vehicles, a separate test is required for each
fuel on which the vehicle is capable of operating. For flexible fuel
vehicles, a single test is required on a fuel that falls within the
range of fuel mixtures for which the vehicle was designed. The test
fuel(s) used must be commercially available.
(B) A converted vehicle shall be considered to meet the requirements
of this paragraph if the vehicle's measured exhaust CO concentration(s)
is lower than the cutpoint(s) used to determine CO pass/fail under the
inspection and maintenance program in the area in which the conversion
is expected to be operated.
(1) If CO pass/fail criteria are not available for a vehicle fuel
type then pass/fail criteria specific to gasoline use are to be used for
vehicles of that fuel type.
(2) [Reserved]
(ii) The carbon monoxide (CO) emissions of the converted vehicle
must be determined in the manner specified in the two speed idle test-
EPA 91 found in 40 CFR 85.2215. All provisions in the two speed idle
test must be observed except as detailed in paragraph (c)(2)(ii)(D) of
this section.
(A) For dual and flexible fuel vehicles, a separate test is required
for each certification test fuel required for exhaust emissions testing
pursuant to 40 CFR 86.113 or 40 CFR 86.1313.
(B) For light-duty vehicles and light-duty trucks the test fuels
used during the emissions testing required by paragraph (c)(4) of this
section must comply with the fuel specifications for exhaust emissions
testing found in 40 CFR 86.113. For heavy-duty engines the test fuels
used during the emissions testing required by paragraph (c)(2) of this
section must comply with the fuel specifications for exhaust emissions
testing found in 40 CFR 86.1313.
(C) A converted vehicle shall be considered to meet the requirements
of this paragraph if the following criteria are satisfied:
(1) The vehicle's measured idle mode exhaust CO concentration(s)
must be lower than the sum of 0.4 percent CO plus the idle mode
certification CO emissions reference value as determined according to

Sec. 88.311-93 Emissions standards for Inherently Low-Emission Vehicles.
(a) Certification. (1) Emissions Testing Procedures. A vehicle shall
be certified as an ILEV if that vehicle satisfies the following
conditions:
(i) The vehicle shall be certified under the appropriate exhaust
emissions standards from paragraph (c) or (d) of this section depending
on the vehicle's weight classification.
(ii) The vehicle shall be certified as having fuel vapor emissions
which are five or less total grams per test as measured by the current
Federal Test Procedure (FTP), modified for ILEV certification, from 40
CFR part 86, subpart B for LDVs and LDTs and from 40 CFR part 86,
subpart M for HDVs.
(A) After disabling any and all auxiliary emission control devices
(canister, purge system, etc.) related to control of evaporative
emissions, the fuel vapor emissions shall be measured using the FTP
regulations in effect at the time the vehicle is to be certified as an
ILEV. For purposes of this section, the vehicle's fuel vapor emissions
shall consist of the total grams of diurnal, hot soak, running loss, and
resting loss emissions, as appropriate, for the particular fuel/vehicle/
engine combination to be tested. In determining ILEV evaporative
emissions, the diurnal emissions measurement procedure shall consist of
a single diurnal heat build using an ambient or fuel temperature range
of 72[deg]-96 [deg]F (22[deg]-36 [deg]C), as appropriate for the
applicable FTP regulations (40 CFR part 86).
[[Page 33]]
(B) Conventional Federal Test Procedure. A vehicle with no
evaporative emissions control system components may have its evaporative
emissions certified for its particular GVWR weight class/subclass if it
passes the conventional evaporative emissions FTP from 40 CFR part 86,
subpart B for LDVs and LDTs or from 40 CFR part 86, subpart M for HDVs,
as applicable.
(iii) The vehicle must meet other special requirements applicable to
conventional or clean-fuel vehicles and their fuels as described in any
other parts of this chapter, including 40 CFR parts 86 and 88.
(2) Vehicles which have a closed or sealed fuel system may be
certified at the administrator's option by engineering evaluation in
lieu of testing. These vehicles will be certified as ILEVs only if a
leak in the fuel system would result in the vehicle becoming inoperative
due to loss of fuel supply, or if half the fuel escapes within 24 hours.
(b) Identification. In the application for a vehicle's certification
as an ILEV, the manufacturer or the manufacturer's agent shall provide
for positive identification of the vehicle's status as an ILEV in the
vehicle's Vehicle Emission Control Information (VECI) label in
accordance with 40 CFR 86.094-35 and 86.095-35. The label shall contain
a highlighted statement (e.g., underscored or boldface letters) that the
vehicle is certified to applicable emission standards for ILEV exhaust
and evaporative emission standards.
(c) Light-duty vehicles and light-duty trucks. ILEVs in LDV and LDT
classes shall have exhaust emissions which do not exceed the LEV exhaust
emission standards for NMOG, CO, HCHO, and PM and the ULEV exhaust
emission standards for NOX listed in Tables A104-1 through
A104-6 for light-duty CFVs. Exhaust emissions shall be measured in
accordance with the test procedures specified in Sec. 88.104-94(k). An
ILEV must be able to operate on only one fuel, or must be certified as
an ILEV on all fuels on which it can operate. These vehicles shall also
comply with all requirements of 40 CFR part 86 which are applicable to
conventional gasoline-fueled, methanol-fueled, diesel-fueled, natural
gas-fueled or liquified petroleum gas-fueled LDVs/LDTs of the same
vehicle class and model year.
(d) Heavy-duty vehicles. ILEVs in the HDV class shall have exhaust
emissions which do not exceed the exhaust emission standards in grams
per brake horsepower-hour listed in Sec. 88.105-94(d). Exhaust
emissions shall be measured in accordance with the test procedures
specified in Sec. 88.105-94(e). An ILEV must be able to operate on only
one fuel, or must be certified as an ILEV on all fuels on which it can
operate. These vehicles shall also comply with all requirements of 40
CFR part 86 which are applicable in the case of conventional gasoline-
fueled, methanol-fueled, diesel-fueled, natural gas-fueled or liquified
petroleum gas-fueled HDVs of the same weight class and model year.
(e) Applicability. State actions to opt out of the clean-fuel fleet
program under section 182(c) of the Act do not affect the applicability
of the ILEV program in the affected states.

0.3 inches (0.8 centimeters). In addition, the words ``CLEAN AIR
VEHICLE'' must be present in lettering no smaller than 0.4 inches (1.0
centimeter) high. Nothing shall be added to the label which impairs
readability. Labels shall include a serialized identification number.
(d) Label removal. Fleet ILEV owners shall remove and dispose of the
ILEV labels on a vehicle before selling or transferring ownership of an
ILEV or offering it for lease (unless the ILEV is part of a daily rental
fleet) or long-term loan. This provision shall not apply if the person
who is receiving the vehicle demonstrates eligibility for expanded TCM
exemptions under the federal ILEV program as described in paragraph (b)
of this section, or is otherwise qualified under state regulations which
expressly expand ILEV label eligibility.
(e) Label replacement. (1) The manufacturer shall make replacement
ILEV labels available to the fleet owner of a qualifying ILEV to replace
any ILEV label which has been lost or removed due to vehicle damage,
repair, sale, or lease. The fleet owner's request shall include proof of
ownership of the ILEV in question and proof of the fleet owner's
eligibility for ILEV TCM exemptions, as outlined in paragraph (c) of
this section. Each label shall be imprinted with the same serial number
as initially assigned to the damaged/missing ILEV label(s) for that
vehicle. Any portion of a damaged label remaining on the ILEV shall be
removed from the vehicle and submitted with the request as proof of
loss.
(2) Upon receipt of the replacement ILEV label(s), the fleet owner
shall attach the new ILEV label(s) only to the vehicle for which
replacement ILEV label(s) were requested.

Sec. 88.313-93 Incentives for the purchase of Inherently Low-Emission
Vehicles.
(a) Administration. (1) The incentives granted to ILEVs provided in
this section are not effective outside of nonattainment areas for which
states are required to establish CFFV programs under section 246 of the
CAA, unless specifically added by states for qualifying vehicles.
(2) Incentives for purchasing ILEVs shall not be transferred between
vehicles within the same fleet nor shall they be sold or traded.
(3) No vehicle over 26,000 pounds (11,800 kilograms) GVWR shall be
eligible for the following ILEV incentives.
(b) Exemption from temporal TCMs. A fleet vehicle which has been
certified and labeled as an ILEV according to the provisions of this
section and which continues to be in compliance with applicable
emissions standards and other ILEV program requirements shall be
exempted from TCMs existing for air quality reasons included in approved
state implementation plans which restrict vehicle usage based primarily
on temporal considerations, such as time-of-day and day-of-week
exemptions.
(c) Exemption from high-occupancy vehicle lane restrictions. (1) A
fleet vehicle which has been certified and labeled as an ILEV according
to the provisions of Sec. Sec. 88.311 and 88.312 and which continues to
be in compliance with applicable emissions standards and other ILEV
program requirements shall be exempt from TCMs which restrict a
vehicle's access to certain roadway lanes based on the number of
occupants in that vehicle, usually known as high-occupancy vehicle (HOV)
lanes. These exemptions shall not apply if they would create a clear and
direct safety hazard.
[[Page 36]]
(2) In a state containing a covered area, or areas, the governor may
petition the Administrator for a waiver from the exemption from HOV lane
restrictions for ILEVs for any section of HOV lane in the covered
area(s) that can be shown to be congested primarily due to the operation
or projected operation of ILEVs. The waiver application shall
demonstrate the infeasibility of other means of alleviating HOV/CAV lane
congestion, such as adding an additional HOV/CAV lane, further
increasing vehicle occupancy requirements and reducing the use of the
lane by noneligible vehicles.

Sec. 89.2 Definitions.
The following definitions apply to part 89. All terms not defined
herein have the meaning given them in the Act.
Act means the Clean Air Act, as amended, 42 U.S.C. 7401 et seq.
Adjustable parameter means any device, system, or element of design
which is physically capable of being adjusted (including those which are
difficult to access) and which, if adjusted, may affect emissions or
engine performance during emission testing.
Administrator means the Administrator of the Environmental
Protection Agency or his or her authorized representative.

not a propulsion marine diesel engine.
Blue Sky Series engine means a nonroad engine meeting the
requirements of Sec. 89.112(f).
Certification means, with respect to new nonroad engines, obtaining
a certificate of conformity for an engine family complying with the
nonroad engine emission standards and requirements specified in this
part.
[[Page 42]]
Compression-ignition means relating to a type of reciprocating,
internal-combustion engine that is not a spark-ignition engine.
Constant-speed engine means an engine that is governed to operate
only at rated speed.
Crankcase emissions means airborne substances emitted to the
atmosphere from any portion of the engine crankcase ventilation or
lubrication systems.
Emission control system means any device, system, or element of
design which controls or reduces the emission of substances from an
engine.
Engine, as used in this part, refers to nonroad engine.
Engine manufacturer means any person engaged in the manufacturing or
assembling of new nonroad engines or importing such engines for resale,
or who acts for and is under the control of any such person in
connection with the distribution of such engines. Engine manufacturer
does not include any dealer with respect to new nonroad engines received
by such person in commerce.
Engine used in a locomotive means either an engine placed in the
locomotive to move other equipment, freight, or passenger traffic, or an
engine mounted on the locomotive to provide auxiliary power.
EPA enforcement officer means any officer or employee of the
Environmental Protection Agency so designated in writing by the
Administrator (or by his or her designee).
Exhaust gas recirculation means an emission control technology that
reduces emissions by routing exhaust gases that had been exhausted from
the combustion chamber(s) back into the engine to be mixed with incoming
air prior to or during combustion. The use of valve timing to increase
the amount of residual exhaust gas in the combustion chamber(s) that is
mixed with incoming air prior to or during combustion is not considered
to be exhaust gas recirculation for the purposes of this part.
Family emission limit (FEL) means an emission level that is declared
by the manufacturer to serve in lieu of an emission standard for
certification purposes and for the averaging, banking, and trading
program. A FEL must be expressed to the same number of decimal places as
the applicable emission standard.
Full load governed speed is the maximum full load speed as specified
by the manufacturer in the sales and service literature and
certification application. This speed is the highest engine speed with
an advertised power greater than zero.
Gross power means the power measured at the crankshaft or its
equivalent, the engine being equipped only with the standard accessories
(such as oil pumps, coolant pumps, and so forth) necessary for its
operation on the test bed. Alternators must be used, if necessary, to
run the engine. Fans, air conditioners, and other accessories may be
used at the discretion of the manufacturer, but no power adjustments for
these accessories may be made.
Identification number means a specification (for example, model
number/serial number combination) which allows a particular nonroad
engine to be distinguished from other similar engines.
Intermediate speed means peak torque speed if peak torque speed
occurs from 60 to 75 percent of rated speed. If peak torque speed is
less than 60 percent of rated speed, intermediate speed means 60 percent
of rated speed. If peak torque speed is greater than 75 percent of rated
speed, intermediate speed means 75 percent of rated speed.
Marine engine means a nonroad engine that is installed or intended
to be installed on a marine vessel. This includes a portable auxiliary
marine engine only if its fueling, cooling, or exhaust system is an
integral part of the vessel. There are two kinds of marine engines:
(1) Propulsion marine engine means a marine engine that moves a
vessel through the water or directs the vessel's movement.
(2) Auxiliary marine engine means a marine engine not used for
propulsion.
Marine vessel has the meaning given in 1 U.S.C. 3, except that it
does not include amphibious vehicles. The definition in 1 U.S.C. 3 very
broadly includes every craft capable of being used as a means of
transportation on water.
[[Page 43]]
Model year (MY) means the manufacturer's annual new model production
period which includes January 1 of the calendar year, ends no later than
December 31 of the calendar year, and does not begin earlier than
January 2 of the previous calendar year. Where a manufacturer has no
annual new model production period, model year means calendar year.
New for purposes of this part, means a nonroad engine, nonroad
vehicle, or nonroad equipment the equitable or legal title to which has
never been transferred to an ultimate purchaser. Where the equitable or
legal title to the engine, vehicle, or equipment is not transferred to
an ultimate purchaser until after the engine, vehicle, or equipment is
placed into service, then the engine, vehicle, or equipment will no
longer be new after it is placed into service. A nonroad engine,
vehicle, or equipment is placed into service when it is used for its
functional purposes. With respect to imported nonroad engines, nonroad
vehicles, or nonroad equipment, the term new means an engine, vehicle,
or piece of equipment that is not covered by a certificate of conformity
issued under this part at the time of importation, and that is
manufactured after the effective date of a regulation issued under this
part which is applicable to such engine, vehicle, or equipment (or which
would be applicable to such engine, vehicle, or equipment had it been
manufactured for importation into the United States).
Nonroad engine means:
(1) Except as discussed in paragraph (2) of this definition, a
nonroad engine is any internal combustion engine:
(i) In or on a piece of equipment that is self-propelled or serves a
dual purpose by both propelling itself and performing another function
(such as garden tractors, off-highway mobile cranes and bulldozers); or
(ii) In or on a piece of equipment that is intended to be propelled
while performing its function (such as lawnmowers and string trimmers);
or
(iii) That, by itself or in or on a piece of equipment, is portable
or transportable, meaning designed to be and capable of being carried or
moved from one location to another. Indicia of transportability include,
but are not limited to, wheels, skids, carrying handles, dolly, trailer,
or platform.
(2) An internal combustion engine is not a nonroad engine if:
(i) the engine is used to propel a motor vehicle or a vehicle used
solely for competition, or is subject to standards promulgated under
section 202 of the Act; or
(ii) the engine is regulated by a federal New Source Performance
Standard promulgated under section 111 of the Act; or
(iii) the engine otherwise included in paragraph (1)(iii) of this
definition remains or will remain at a location for more than 12
consecutive months or a shorter period of time for an engine located at
a seasonal source. A location is any single site at a building,
structure, facility, or installation. Any engine (or engines) that
replaces an engine at a location and that is intended to perform the
same or similar function as the engine replaced will be included in
calculating the consecutive time period. An engine located at a seasonal
source is an engine that remains at a seasonal source during the full
annual operating period of the seasonal source. A seasonal source is a
stationary source that remains in a single location on a permanent basis
(i.e., at least two years) and that operates at that single location
approximately three months (or more) each year. This paragraph does not
apply to an engine after the engine is removed from the location.
Nonroad equipment means equipment that is powered by nonroad
engines.
Nonroad vehicle means a vehicle that is powered by a nonroad engine
as defined in this section and that is not a motor vehicle or a vehicle
used solely for competition.
Nonroad vehicle or nonroad equipment manufacturer means any person
engaged in the manufacturing or assembling of new nonroad vehicles or
equipment r importing such vehicles or equipment for resale, or who acts
for and is under the control of any such person in connection with the
distribution of such vehicles or equipment. A nonroad vehicle or
equipment manufacturer does not include any dealer with respect to new
nonroad vehicles
[[Page 44]]
or equipment received by such person in commerce. A nonroad vehicle or
equipment manufacturer does not include any person engaged in the
manufacturing or assembling of new nonroad vehicles or equipment who
does not install an engine as part of that manufacturing or assembling
process. All nonroad vehicle or equipment manufacturing entities that
are under the control of the same person are considered to be a single
nonroad vehicle or nonroad equipment manufacturer.
Opacity means the fraction of a beam of light, expressed in percent,
which fails to penetrate a plume of smoke.
Operating hours means:
(1) For engine storage areas or facilities, all times during which
personnel other than custodial personnel are at work in the vicinity of
the storage area or facility and have access to it.
(2) For all other areas or facilities, all times during which an
assembly line is in operation or all times during which testing,
maintenance, service accumulation, production or compilation of records,
or any other procedure or activity related to certification testing, to
translation of designs from the test stage to the production stage, or
to engine manufacture or assembly is being carried out in a facility.
Post-manufacture marinizer means a person who produces a marine
diesel engine by substantially modifying a certified or uncertified
complete or partially complete engine, and is not controlled by the
manufacturer of the base engine or by an entity that also controls the
manufacturer of the base engine. For the purpose of this definition,
``substantially modify'' means changing an engine in a way that could
change engine emission characteristics.
Presentation of credentials means the display of the document
designating a person as an EPA enforcement officer or EPA authorized
representative.
Propulsion marine diesel engine means a marine diesel engine that is
intended to move a vessel through the water or direct the movement of a
vessel.
Rated speed is the maximum full load governed speed for governed
engines and the speed of maximum horsepower for ungoverned engines.
Spark-ignition means relating to a gasoline-fueled engine or other
engines with a spark plug (or other sparking device) and with operating
characteristics significantly similar to the theoretical Otto combustion
cycle. Spark-ignition engines usually use a throttle to regulate intake
air flow to control power during normal operation.
Specific emissions means emissions expressed on the basis of
observed brake power, using units of g/kW-hr. Observed brake power
measurement includes accessories on the engine if these accessories are
required for running an emission test (except for the cooling fan). When
it is not possible to test the engine in the gross conditions, for
example, if the engine and transmission form a single integral unit, the
engine may be tested in the net condition. Power corrections from net to
gross conditions will be allowed with prior approval of the
Administrator.
Sulfur-sensitive technology means an emission-control technology
that experiences a significant drop in emission-control performance or
emission-system durability when an engine is operated on low-sulfur fuel
(i.e., fuel with a sulfur concentration up to 500 ppm) as compared to
when it is operated on ultra low-sulfur fuel (i.e., fuel with a sulfur
concentration less than 15 ppm). Exhaust-gas recirculation is not a
sulfur-sensitive technology.
Test fleet means the engine or group of engines that a manufacturer
uses during certification to determine compliance with emission
standards.
Tier 1 engine means an engine subject to the Tier 1 emission
standards listed in Sec. 89.112(a).
Tier 2 engine means an engine subject to the Tier 2 emission
standards listed in Sec. 89.112(a).
Tier 3 engine means an engine subject to the Tier 3 emission
standards listed in Sec. 89.112(a).
Ultimate purchaser means, with respect to any new nonroad engine,
new nonroad vehicle, or new nonroad equipment, the first person who in
good faith purchases such new nonroad engine, nonroad vehicle, or
nonroad equipment for purposes other than resale.
[[Page 45]]
United States means the States, the District of Columbia, the
Commonwealth of Puerto Rico, the Commonwealth of the Northern Mariana
Islands, Guam, American Samoa, and the U.S. Virgin Islands.
Used solely for competition means exhibiting features that are not
easily removed and that would render its use other than in competition
unsafe, impractical, or highly unlikely.
U.S.-directed production volume means the number of nonroad
equipment, vehicle, or marine diesel engine units produced by a
manufacturer for which the manufacturer has reasonable assurance that
sale was or will be made to ultimate purchasers in the United States.

Appendix A to Subpart A of Part 89--State Regulation of Nonroad Internal
Combustion Engines
This appendix sets forth the Environmental Protection Agency's
(EPA's) interpretation of the Clean Air Act regarding the authority of
states to regulate the use and operation of nonroad engines.
EPA believes that states are not precluded under section 209 from
regulating the use and operation of nonroad engines, such as regulations
on hours of usage, daily mass emission limits, or sulfur limits on fuel;
nor are permits regulating such operations precluded, once the engine is
no longer new. EPA believes that states are precluded from requiring
retrofitting of used nonroad engines except that states are permitted to
[[Page 47]]
adopt and enforce any such retrofitting requirements identical to
California requirements which have been authorized by EPA under section
209 of the Clean Air Act.
[62 FR 67736, Dec. 30, 1997]
Subpart B_Emission Standards and Certification Provisions
Sec. 89.101 Applicability.
The requirements of subpart B are applicable to all new nonroad
compression-ignition engines subject to the provisions of subpart A of
part 89, pursuant to the schedule delineated in Sec. 89.102.
[59 FR 31335, June 17, 1994. Redesignated at 63 FR 56995, Oct. 23, 1998]
Sec. 89.102 Effective dates, optional inclusion, flexibility for equipment
manufacturers.
(a) This subpart applies to all engines described in Sec. 89.101
with the following power rating and manufactured after the following
dates:
(1) Less than 19 kW and manufactured on or after January 1, 2000;
(2) Greater than or equal to 19 kW but less than 37 kW and
manufactured on or after January 1, 1999;
(3) Greater than or equal to 37 kW but less than 75 kW and

and manufactured on or after January 1, 1996;
(6) Greater than 560 kW and manufactured on or after January 1,
2000.
(b) A manufacturer can optionally certify engines manufactured up to
one calendar year prior to the effective date of mandatory certification
to earn emission credits under the averaging, banking, and trading
program. Such optionally certified engines are subject to all provisions
relating to mandatory certification and enforcement described in this
part.
(c) Engines meeting the voluntary standards described in Sec.
89.112(f) may be designated as Blue Sky Series engines through the 2004
model year.
(d) Implementation flexibility for equipment and vehicle
manufacturers and post-manufacture marinizers. Nonroad equipment and
vehicle manufacturers and post-manufacture marinizers may take any of
the otherwise prohibited actions identified in Sec. 89.1003(a)(1) with
respect to nonroad equipment and vehicles and marine diesel engines,
subject to the requirements of paragraph (e) of this section. The
following allowances apply separately to each engine power category
subject to standards under Sec. 89.112:
(1) Percent-of-production allowances. (i) Equipment rated at or
above 37 kW. For nonroad equipment and vehicles with engines rated at or
above 37 kW, a manufacturer may take any of the actions identified in
Sec. 89.1003(a)(1) for a portion of its U.S.-directed production volume
of such equipment and vehicles during the seven years immediately
following the date on which Tier 2 engine standards first apply to
engines used in such equipment and vehicles, provided that the seven-
year sum of these portions in each year, as expressed as a percentage
for each year, does not exceed 80, and provided that all such equipment
and vehicles or equipment contain Tier 1 or Tier 2 engines;
(ii) Equipment rated under 37 kW. For nonroad equipment and vehicles
and marine diesel engines with engines rated under 37 kW, a manufacturer
may take any of the actions identified in Sec. 89.1003(a)(1) for a
portion of its U.S.-directed production volume of such equipment and
vehicles during the seven years immediately following the date on which
Tier 1 engine standards first apply to engines used in such equipment
and vehicles, provided that the seven-year sum of these portions in each
year, as expressed as a percentage for each year, does not exceed 80.
(2) Small volume allowances. A nonroad equipment or vehicle
manufacturer or post-manufacture marinizer may exceed the production
percentages in paragraph (d)(1) of this section, provided that in each
regulated power category the manufacturer's total of excepted nonroad
equipment and vehicles and marine diesel engines:
(i) Over the years in which the percent-of-production allowance
applies does not exceed 100 units times the
[[Page 48]]
number of years in which the percent-of-production allowance applies;
and
(ii) Does not exceed 200 units in any year; and
(iii) Does not use engines from more than one engine family, or, for
excepted equipment vehicles, and marine diesel engines using engines not
belonging to any engine family, from more than one engine manufacturer.
(3) Inclusion of previous-tier engines. Nonroad equipment and
vehicles and marine diesel engines built with previous tier or
noncertified engines under the existing inventory provisions of Sec.
89.1003(b)(4) need not be included in determining compliance with
paragraphs (d)(1) and (d)(2) of this section.
(e) Recordkeeping and calculation to verify compliance. The
following shall apply to nonroad equipment or vehicle manufacturers and
post-manufacture marinizers who produce excepted equipment or vehicles
or marine diesel engines under the provisions of paragraph (d) of this
section:
(1) For each power category in which excepted nonroad equipment or
vehicles or marine diesel engines are produced, a calculation to verify
compliance with the requirements of paragraph (d) of this section shall
be made by the nonroad equipment or vehicle manufacturer or post-
manufacture marinizer. This calculation shall be made no later than
December 31 of the year following the last year in which allowances are
used, and shall be based on actual production information from the
subject years. If both the percent-of-production and small volume
allowances have been exceeded, then the manufacturer is in violation of
section 203 of the Act and Sec. 89.1003, except as provided under
paragraphs (f) and (h) of this section.
(2) A nonroad equipment or vehicle manufacturer or post-manufacture
marinizer shall keep records of all nonroad equipment and vehicles and
marine diesel engines excepted under the provisions of paragraph (d) of
this section, for each power category in which exceptions are taken.
These records shall include equipment and engine model numbers, serial
numbers, and dates of manufacture, and engine rated power. In addition,
the manufacturer shall keep records sufficient to demonstrate the
verifications of compliance required in paragraph (e)(1) of this
section. All records shall be kept until at least two full years after
the final year in which allowances are available for each power
category, and shall be made available to EPA upon request.
(f) Hardship relief. Nonroad equipment and vehicle manufacturers and
post-manufacture marinizers may take any of the otherwise prohibited
actions identified in Sec. 89.1003(a)(1) if approved by the
Administrator, and subject to the following requirements:
(1) Application for relief must be submitted to the Engine Programs
and Compliance Division of the EPA in writing prior to the earliest date
in which the applying manufacturer would be in violation of Sec.
89.1003. The manufacturer must submit evidence showing that the
requirements for approval have been met.
(2) The applying manufacturer must not be the manufacturer of the
engines used in the equipment for which relief is sought. This
requirement does not apply to post-manufacture marinizers.
(3) The conditions causing the impending violation must not be
substantially the fault of the applying manufacturer.
(4) The conditions causing the impending violation must be such that
the applying manufacturer will experience serious economic hardship if
relief is not granted.
(5) The applying manufacturer must demonstrate that no allowances
under paragraph (d) of this section will be available to avoid the
impending violation.
(6) Any relief granted must begin within one year after the
implementation date of the standard applying to the engines being used
in the equipment, or to the marine diesel engines, for which relief is
requested, and may not exceed one year in duration.
(7) The Administrator may impose other conditions on the granting of
relief including provisions to recover the lost environmental benefit.
(g) Allowance for the production of engines. Engine manufacturers
may take any of the otherwise prohibited actions identified in Sec.
89.1003(a)(1) with regard
[[Page 49]]
to uncertified engines or Tier 1 engines, as appropriate, if the engine
manufacturer has received written assurance from the equipment
manufacturer that the engine is required to meet the demand for engines
created under paragraph (d), (f), or (h) of this section.
(h) Alternative Flexibility for Post-Manufacture Marinizers. Post-
manufacture marinizers may elect to delay the effective date of the Tier
1 standards in Sec. 89.112 for marine diesel engines rated under 37 kW
by one year, instead of using the provisions of paragraphs (d) and (f)
of this section. Post-manufacture marinizers wishing to take advantage
of this provision must inform the Director of the Engine Programs and
Compliance Division of their intent to do so in writing before the date
that the standards would otherwise take effect.

Sec. 89.103 Definitions.
The definitions in subpart A of part 89 apply to this subpart. All
terms not defined herein or in subpart A have the meaning given them in
the Act.
[59 FR 31335, June 17, 1994. Redesignated at 63 FR 56995, Oct. 23, 1998]
Sec. 89.104 Useful life, recall, and warranty periods.
(a) The useful life is based on the rated power and rated speed of
the engine.
(1) For all engines rated under 19 kW, and for constant speed
engines rated under 37 kW with rated speeds greater than or equal to
3,000 rpm, the useful life is a period of 3,000 hours or five years of
use, whichever first occurs.
(2) For all other engines rated at or above 19 kW and under 37 kW,
the useful life is a period of 5,000 hours or seven years of use,
whichever first occurs.
(3) For all engines rated at or above 37 kW, the useful life is a
period of 8,000 hours of operation or ten years of use, whichever first
occurs.
(b) Engines are subject to recall testing for a period based on the
rated power and rated speed of the engines. However, in a recall,
engines in the subject class or category would be subject to recall
regardless of actual years or hours of operation.
(1) For all engines rated under 19 kW, and for constant speed
engines rated under 37 kW with rated speeds greater than or equal to
3,000 rpm, the engines are subject to recall testing for a period of
2,250 hours or four years of use, whichever first occurs.
(2) For all other engines rated at or above 19 kW and under 37 kW,
the engines are subject to recall for a period of 3,750 hours or five
years of use, whichever first occurs.
(3) For all engines rated at or above 37 kW, the engines are subject
to recall for a period of 6,000 hours of operation or seven years of
use, whichever first occurs.
(c) The warranty periods for warranties imposed by the Clean Air Act
and Sec. 89.1007 for all engines rated under 19 kW, and for constant
speed engines rated under 37 kW with rated speeds greater than or equal
to 3,000 rpm, are 1,500 hours of operation or two years of use,
whichever first occurs. For all other engines, the warranty periods for
warranties imposed by the Clean Air Act and Sec. 89.1007 are 3,000
hours of operation or five years of use, whichever first occurs.
(d) Manufacturers may apply to the Administrator for approval for a
shorter useful life period for engines that are subject to severe
service in seasonal equipment, or are designed specifically for lower
useful life hours to match equipment life. Such an application must be
made prior to certification.
[59 FR 31335, June 17, 1994. Redesignated and amended at 63 FR 56995,
56998, Oct. 23, 1998]
Sec. 89.105 Certificate of conformity.
Every manufacturer of a new nonroad compression-ignition engine must
obtain a certificate of conformity covering the engine family, as
described in Sec. 89.116. The certificate of conformity must be
obtained from the Administrator prior to selling, offering for sale,
introducing into commerce, or importing into the United States the
[[Page 50]]
new nonroad compression-ignition engine for each model year.
[59 FR 31335, June 17, 1994. Redesignated at 63 FR 56995, Oct. 23, 1998]
Sec. 89.106 Prohibited controls.
(a) An engine may not be equipped with an emission control system
for the purpose of complying with emission standards if such system will
cause or contribute to an unreasonable risk to public health, welfare,
or safety in its operation or function.
(b) You may not design your engines with emission-control devices,
systems, or elements of design that cause or contribute to an
unreasonable risk to public health, welfare, or safety while operating.
For example, this would apply if the engine emits a noxious or toxic
substance it would otherwise not emit that contributes to such an
unreasonable risk.
[59 FR 31335, June 17, 1994. Redesignated at 63 FR 56995, Oct. 23, 1998;
67 FR 68339, Nov. 8, 2002]
Sec. 89.107 Defeat devices.
(a) An engine may not be equipped with a defeat device.
(b) For purposes of this section, ``defeat device'' means any
device, system, or element of design which senses operation outside
normal emission test conditions and reduces emission control
effectiveness.
(1) Defeat device includes any auxiliary emission control device
(AECD) that reduces the effectiveness of the emission control system
under conditions which may reasonably be expected to be encountered in
normal operation and use unless such conditions are included in the test
procedure.
(2) Defeat device does not include such items which either operate
only during engine starting or are necessary to protect the engine (or
equipment in which it is installed) against damage or accident during
its operation.
[59 FR 31335, June 17, 1994. Redesignated at 63 FR 56995, Oct. 23, 1998]
Sec. 89.108 Adjustable parameters, requirements.
(a) Nonroad engines equipped with adjustable parameters must comply
with all requirements of this subpart for any adjustment in the
physically adjustable range.
(b) An operating parameter is not considered adjustable if it is
permanently sealed or otherwise not normally accessible using ordinary
tools.
(c) The Administrator may require that adjustable parameters be set
to any specification within its adjustable range for certification,
selective enforcement audit, or in-use testing to determine compliance
with the requirements of this subpart.
[59 FR 31335, June 17, 1994. Redesignated at 63 FR 56995, Oct. 23, 1998]
Sec. 89.109 Maintenance instructions and minimum allowable maintenance
intervals.
(a) The manufacturer must furnish or cause to be furnished to the
ultimate purchaser of each new nonroad engine subject to standards under
this part written instructions for the maintenance needed to ensure
proper functioning of the emission control system. Paragraphs (b)
through (h) of this section do not apply to Tier 1 engines with rated
power at or above 37 kW.
(b) Maintenance performed on equipment, engines, subsystems or
components used to determine exhaust emission deterioration factors is
classified as either emission-related or nonemission-related and each of
these can be classified as either scheduled or unscheduled. Further,
some emission-related maintenance is also classified as critical
emission-related maintenance.
(c) This paragraph (c) specifies emission-related scheduled
maintenance for purposes of obtaining durability data for nonroad
engines. The maintenance intervals specified below are minimum
intervals:
(1) All emission-related scheduled maintenance for purposes of
obtaining durability data must occur at the same or longer hours of use
intervals as those specified in the manufacturer's maintenance
instructions furnished to the ultimate purchaser of the engine under
paragraph (a) of this section. This maintenance schedule may be updated
as necessary throughout the testing of the engine, provided that no
maintenance operation is deleted from
[[Page 51]]
the maintenance schedule after the operation has been performed on the
test equipment or engine.
(2) Any emission-related maintenance which is performed on
equipment, engines, subsystems, or components must be technologically
necessary to ensure in-use compliance with the emission standards. The
manufacturer must submit data which demonstrate to the Administrator
that all of the emission-related scheduled maintenance which is to be
performed is technologically necessary. Scheduled maintenance must be
approved by the Administrator prior to being performed or being included
in the maintenance instructions provided to the purchasers under
paragraph (a) of this section.
(i) The Administrator may require longer maintenance intervals than
those listed in paragraphs (c)(3) and (c)(4) of this section where the
listed intervals are not technologically necessary.
(ii) The Administrator may allow manufacturers to specify shorter
maintenance intervals than those listed in paragraphs (c)(3) and (c)(4)
of this section where technologically necessary for engines rated under
19 kW, or for constant speed engines rated under 37 kW with rated speeds
greater than or equal to 3,000 rpm.
(3) The adjustment, cleaning, repair, or replacement of items listed
in paragraphs (c)(3)(i) through (c)(3)(iii) of this section shall occur
at 1,500 hours of use and at 1,500-hour intervals thereafter.
(i) Exhaust gas recirculation system-related filters and coolers.
(ii) Positive crankcase ventilation valve.
(iii) Fuel injector tips (cleaning only).
(4) The adjustment, cleaning and repair of items in paragraphs
(c)(4)(i) through (c)(4)(vii) of this section shall occur at 3,000 hours
of use and at 3,000-hour intervals thereafter for nonroad compression-
ignition engines rated under 130 kW, or at 4,500-hour intervals
thereafter for nonroad compression-ignition engines rated at or above
130 kW.
(i) Fuel injectors.
(ii) Turbocharger.
(iii) Electronic engine control unit and its associated sensors and
actuators.
(iv) Particulate trap or trap-oxidizer system (including related
components).
(v) Exhaust gas recirculation system (including all related control
valves and tubing) except as otherwise provided in paragraph (c)(3)(i)
of this section.
(vi) Catalytic convertor.
(vii) Any other add-on emission-related component (i.e., a component
whose sole or primary purpose is to reduce emissions or whose failure
will significantly degrade emission control and whose function is not
integral to the design and performance of the engine).
(d) Scheduled maintenance not related to emissions which is
reasonable and technologically necessary (e.g., oil change, oil filter
change, fuel filter change, air filter change, cooling system
maintenance, adjustment of idle speed, governor, engine bolt torque,
valve lash, injector lash, timing, lubrication of the exhaust manifold
heat control valve, etc.) may be performed on durability vehicles at the
least frequent intervals recommended by the manufacturer to the ultimate
purchaser, (e.g., not the intervals recommended for severe service).
(e) Adjustment of engine idle speed on emission data engines may be
performed once before the low-hour emission test point. Any other
engine, emission control system, or fuel system adjustment, repair,
removal, disassembly, cleaning, or replacement on emission data vehicles
shall be performed only with advance approval of the Administrator.
(f) Equipment, instruments, or tools may not be used to identify
malfunctioning, maladjusted, or defective engine components unless the
same or equivalent equipment, instruments, or tools will be available to
dealerships and other service outlets and:
(1) Are used in conjunction with scheduled maintenance on such
components; or
(2) Are used subsequent to the identification of a vehicle or engine
malfunction, as provided in paragraph (e) of this section for emission
data engines; or
[[Page 52]]
(3) Specifically authorized by the Administrator.
(g) All test data, maintenance reports, and required engineering
reports shall be compiled and provided to the Administrator in
accordance with Sec. 89.124.
(h)(1) The components listed in paragraphs (h)(1)(i) through
(h)(1)(vi) of this section are defined as critical emission-related
components.
(i) Catalytic converter.
(ii) Electronic engine control unit and its associated sensors and
actuators.
(iii) Exhaust gas recirculation system (including all related
filters, coolers, control valves, and tubing).
(iv) Positive crankcase ventilation valve.
(v) Particulate trap or trap-oxidizer system.
(vi) Any other add-on emission-related component (i.e., a component
whose sole or primary purpose is to reduce emissions or whose failure
will significantly degrade emission control and whose function is not
integral to the design and performance of the engine).
(2) All critical emission-related scheduled maintenance must have a
reasonable likelihood of being performed in use. The manufacturer must
show the reasonable likelihood of such maintenance being performed in-
use. Critical emission-related scheduled maintenance items which satisfy
one of the conditions defined in paragraphs (h)(2)(i) through (h)(2)(vi)
of this section will be accepted as having a reasonable likelihood of
being performed in use.
(i) Data are presented which establish for the Administrator a
connection between emissions and vehicle performance such that as
emissions increase due to lack of maintenance, vehicle performance will
simultaneously deteriorate to a point unacceptable for typical
operation.
(ii) Survey data are submitted which adequately demonstrate to the
Administrator with an 80 percent confidence level that 80 percent of
such engines already have this critical maintenance item performed in-
use at the recommended interval(s).
(iii) A clearly displayed visible signal system approved by the
Administrator is installed to alert the equipment operator that
maintenance is due. A signal bearing the message ``maintenance needed''
or ``check engine,'' or a similar message approved by the Administrator,
shall be actuated at the appropriate usage point or by component
failure. This signal must be continuous while the engine is in operation
and not be easily eliminated without performance of the required
maintenance. Resetting the signal shall be a required step in the
maintenance operation. The method for resetting the signal system shall
be approved by the Administrator. The system must not be designed to
deactivate upon the end of the useful life of the engine or thereafter.
(iv) A manufacturer may desire to demonstrate through a survey that
a critical maintenance item is likely to be performed without a visible
signal on a maintenance item for which there is no prior in-use
experience without the signal. To that end, the manufacturer may in a
given model year market up to 200 randomly selected vehicles per
critical emission-related maintenance item without such visible signals,
and monitor the performance of the critical maintenance item by the
owners to show compliance with paragraph (h)(2)(ii) of this section.
This option is restricted to two consecutive model years and may not be
repeated until any previous survey has been completed. If the critical
maintenance involves more than one engine family, the sample will be
sales weighted to ensure that it is representative of all the families
in question.
(v) The manufacturer provides the maintenance free of charge, and
clearly informs the customer that the maintenance is free in the
instructions provided under paragraph (a) of this section.
(vi) The manufacturer uses any other method which the Administrator
approves as establishing a reasonable likelihood that the critical
maintenance will be performed in-use.
(3) Visible signal systems used under paragraph (h)(2)(iii) of this
section are considered an element of design of the emission control
system. Therefore,
[[Page 53]]
disabling, resetting, or otherwise rendering such signals inoperative
without also performing the indicated maintenance procedure is a
prohibited act.
[63 FR 56999, Oct. 23, 1998]
Sec. 89.110 Emission control information label.
(a) The manufacturer must affix at the time of manufacture a
permanent and legible label identifying each nonroad engine. The label
must meet the following requirements:
(1) Be attached in such a manner that it cannot be removed without
destroying or defacing the label;
(2) Be durable and readable for the entire engine life;
(3) Be secured to an engine part necessary for normal engine
operation and not normally requiring replacement during engine life;
(4) Be written in English; and

the exhaust and included in all exhaust emission measurements. This
provision applies to all
[[Page 57]]
Tier 2 engines and later models. This provision does not apply to
engines using turbochargers, pumps, blowers, or superchargers for air
induction.
(f) The following paragraphs define the requirements for low-
emitting Blue Sky Series engines:
(1) Voluntary standards. Engines may be designated ``Blue Sky
Series'' engines by meeting the voluntary standards listed in Table 3,
which apply to all certification and in-use testing, as follows:

------------------------------------------------------------------------
(2) Additional standards. Blue Sky Series engines are subject to all
provisions that would otherwise apply under this part, except as
specified in paragraph (f)(3) of this section.
(3) Test procedures. NOX, NMHC, and PM emissions are
measured using the procedures set forth in 40 CFR part 1065, in lieu of
the procedures set forth in subpart E of this part. CO emissions may be
measured using the procedures set forth either in 40 CFR part 1065 or in
subpart E of this part. Manufacturers may use an alternate procedure to
demonstrate the desired level of emission control if approved in advance
by the Administrator. Engines meeting the requirements to qualify as
Blue Sky Series engines must be capable of maintaining a comparable
level of emission control when tested using the procedures set forth in
paragraph (c) of this section and subpart E of this part. The numerical
emission levels measured using the procedures from subpart E of this
part may be up to 20 percent higher than those measured using the
procedures from 40 CFR part 1065 and still be considered comparable.
(g) Manufacturers of engines at or above 37 kW and below 56 kW from
model years 2008 through 2012 that are subject to the standards of this
section under 40 CFR 1039.102 must take the following additional steps:
(1) State the applicable PM standard on the emission control
information label.
(2) Add information to the emission-related installation
instructions to clarify the equipment manufacturer's obligations under
40 CFR 1039.104(f).

Sec. 89.114 Special and alternate test procedures.
(a) Special test procedures. The Administrator may, on the basis of
written application by a manufacturer, establish special test procedures
other than those set forth in this part, for any nonroad engine that the
Administrator determines is not susceptible to satisfactory testing
under the specified test procedures set forth in subpart E of this part
or 40 CFR part 86, subpart I.
(b) Alternate test procedures. (1) A manufacturer may elect to use
an alternate test procedure provided that it yields equivalent results
to the specified procedures, its use is approved in
[[Page 58]]
advance by the Administrator, and the basis for equivalent results with
the specified test procedures is fully described in the manufacturer's
application.
(2) The Administrator may reject data generated under alternate test
procedures which do not correlate with data generated under the
specified procedures.
(3) A manufacturer may elect to use the test procedures in 40 CFR
part 1065 as an alternate test procedure without advance approval by the
Administrator. The manufacturer must identify in its application for
certification that the engines were tested using the procedures in 40
CFR part 1065. For any EPA testing with Tier 2 or Tier 3 engines, EPA
will use the manufacturer's selected procedures for mapping engines,
generating duty cycles, and applying cycle-validation criteria. For any
other parameters, EPA may conduct testing using either of the specified
procedures.
(4) Where we specify mandatory compliance with the procedures of 40
CFR part 1065, such as in Sec. 89.419, manufacturers may elect to use
the procedures specified in 40 CFR part 86, subpart N, as an alternate
test procedure without advance approval by the Administrator.

Sec. 89.116 Engine families.
(a) A manufacturer's product line is divided into engine families
that are comprised of engines expected to have similar emission
characteristics throughout their useful life periods.
(b) The following characteristics distinguish engine families:
(1) Fuel;
(2) Cooling medium;
(3) Method of air aspiration;
(4) Method of exhaust aftertreatment (for example, catalytic
converter or particulate trap);
(5) Combustion chamber design;
(6) Bore;
(7) Stroke;
(8) Number of cylinders, (engines with aftertreatment devices only);
and
(9) Cylinder arrangement (engines with aftertreatment devices only).
(c) Upon a showing by the manufacturer that the useful life period
emission characteristics are expected to be similar, engines differing
in one or more of the characteristics in paragraph (b) of this section
may be grouped in the same engine family.
(d) Upon a showing by the manufacturer that the expected useful life
period emission characteristics will be different, engines identical in
all the characteristics of paragraph (b) of this section may be divided
into separate engine families.
(e)(1) This paragraph (e) applies only to the placement of Tier 1
engines with power ratings under 37 kW into engine families. The
provisions of paragraphs (a) through (d) of this section also apply to
these engines. The power categories referred to in this paragraph (e)
are those for which separate standards or implementation dates are
described in Sec. 89.112.
(2) A manufacturer may place engines with power ratings in one power
category into an engine family comprised of engines with power ratings
in another power category, and consider all engines in the engine family
as being in the latter power category for the purpose of determining
compliance with the standards and other requirements of this part,
subject to approval in advance by the Administrator and the following
restrictions:
(i) The engines that have power ratings outside the engine family's
power category must constitute less than half of the engine family's
sales in each model year for which the engine family grouping is made;
and
(ii) The engines that have power ratings outside the engine family's
power category must have power ratings that are within ten percent of
either of the two power levels that define the engine family's power
category.
(3) The restrictions described in paragraphs (e)(2)(i) and
(e)(2)(ii) of this section do not apply if the emissions standards and
other requirements of this part are at least as stringent for the engine
family's power category as those of the other power categories
containing engines in the engine family.

Sec. 89.118 Deterioration factors and service accumulation.
This section applies to service accumulation used to determine
deterioration factors and service accumulation used to condition test
engines. Paragraphs (a) and (b) of this section apply only for service
accumulation used to condition test engines. Paragraph (e) of this
section applies only for service accumulation used to determine
deterioration factors. Paragraphs (c) and (d) of this section apply for
all service accumulation required by this part.
(a)(1) Each test engine in the test fleet must be operated with all
emission control systems operating properly for a period sufficient to
stabilize emissions.
(2) A manufacturer may elect to consider as stabilized emission
levels from engines with no more than 125 hours of service.
(b) No maintenance, other than recommended lubrication and filter
changes, may be performed during service accumulation without the
Administrator's approval.
(c) Service accumulation should be performed in a manner using good
engineering judgment to ensure that emissions are representative of in-
use engines.
(d) The manufacturer must maintain, and provide to the Administrator
if requested, records stating the rationale for selecting the service
accumulation period and records describing the method used to accumulate
service hours on the test engine(s).
(e) This paragraph (e) describes service accumulation and
alternative requirements for the purpose of developing deterioration
factor.
(1) Service accumulation on engines, subsystems, or components
selected by the manufacturer under Sec. 89.117(d). The manufacturer
shall describe the form and extent of this service accumulation in the
application for certification.
(2) Determination of exhaust emission deterioration factors. The
manufacturer shall determine the deterioration factors in accordance
with the applicable provisions of this part based on service
accumulation and related testing, according to the manufacturer's
procedures, except as provided in paragraph (e)(3) of this section.
(3) Alternatives to service accumulation and testing for the
determination of a deterioration factor. A written explanation of the
appropriateness of using an alternative must be included in the
application for certification.
(i) Carryover and carryacross of durability emission data. In lieu
of testing an emission data or durability data engine selected under
Sec. 89.117(d), a manufacturer may, with Administrator approval, use
exhaust emission deterioration data on a similar engine for which
certification to the same standard has previously been obtained or for
which all applicable data required under Sec. 89.124 has previously
been submitted. This data must be submitted in the application for
certification.
(ii) Use of on-highway deterioration data. In the case where a
manufacturer produces a certified on-highway engine that is similar to
the nonroad engine to be certified, deterioration data from the on-
highway engine may be applied to the nonroad engine. This application of
deterioration data from an on-highway engine to a nonroad engine is
subject to Administrator approval, and the determination of whether the
engines are similar must be based on good engineering judgment.
[[Page 61]]
(iii) Engineering analysis for established technologies. (A) In the
case where an engine family uses established technology, an analysis
based on good engineering practices may be used in lieu of testing to
determine a deterioration factor for that engine family, subject to
Administrator approval.
(B) Engines for which the certification levels are not at or below
the Tier 3 NMHC+NOX standards described in Sec. 89.112 are
considered established technology, except as provided in paragraph
(e)(3)(iii)(D) of this section.
(C) Manufacturers may petition the Administrator to consider an
engine with a certification level below the Tier 3 +NOX
standards as established technology. This petition must be based on
proof that the technology used is not significantly different than that
used on engines that have certification levels that are not below the
Tier 3 NMHC+NOX levels.
(D) Engines using exhaust gas recirculation or aftertreatment are
excluded from the provision set forth in paragraphs (e)(3)(iii)(A)
through (e)(3)(iii)(C) of this section.
(E) The manufacturer shall provide a written statement to the
Administrator that all data, analyses, test procedures, evaluations, and
other documents, on which the deterioration factor is based, are
available to the Administrator upon request.
(iv) Interim provision for engines rated under 37 kW. For model year
1999 and 2000 engines rated under 37 kW, manufacturers may determine
deterioration factors based on good engineering judgement and reasonably
available information. The manufacturer must maintain and provide to the
Administrator, if requested, all information used to determine
deterioration factors for these engines.

57003, Oct. 23, 1998]
Sec. 89.119 Emission tests.
(a) Manufacturer testing. (1) Upon completion of service
accumulation, the manufacturer must test each test engine using the
specified test procedures, except as provided in Sec. 89.114. The
procedures to be used are set forth in:
(i) Subpart E of this part;
(ii) The California Regulations for New 1996 and Later Heavy-Duty
Off-Road Diesel Cycle Engines. This procedure has been incorporated by
reference. See Sec. 89.6; and
(iii) Part 86, subpart I of this chapter.
(2) Each test engine must be configured to be representative of
actual in-use operation. The Administrator may specify the adjustment of
any adjustable parameter. All test results must be reported to the
Administrator.
(b) Confirmatory testing. The Administrator may conduct confirmatory
testing or other testing on any test engine. The manufacturer must
deliver test engines as directed by the Administrator. When the
Administrator conducts confirmatory testing or other testing, those test
results are used to determine compliance with emission standards.
(c) Use of carryover test data. In lieu of testing to certify an
engine family for a given model year, the manufacturer may submit, with
the Administrator's approval, emission test data used to certify that
engine family in previous years. This ``carryover'' data is only
allowable if the submitted test data show that the test engine would
comply with the emission standard(s) for the model year for which
certification is being sought.
(d) The provisions of this paragraph (d) apply only to Tier 1
nonroad engines without exhaust aftertreatment rated at or above 37 kW.
(1) Particulate emission measurements from Tier 1 nonroad engines
without exhaust aftertreatment rated at or above 37 kW may be adjusted
to a sulfur content of 0.05 weight percent.
(2) Adjustments to the particulate measurement shall be made using
the following equation:
PMadj=PM-[BSFC x 0.0917 x (FSF-0.0005)]
Where:
PMadj=adjusted measured PM level [g/Kw-hr].
PM=measured weighted PM level [g/Kw-hr].
BSFC=measured brake specific fuel consumption [G/Kw-hr].
FSF=fuel sulfur weight fraction.
(3) Where a manufacturer certifies using test fuel with a sulfur
content less than or equal to 0.050 weight percent, EPA shall not use
emission data
[[Page 62]]
collected using test fuel with a sulfur content greater than 0.050
weight percent to determine compliance with the Tier 1 PM standards.
(4) Where a manufacturer certifies using test fuel with a sulfur
content greater than 0.050 weight percent, EPA shall not use emission
data collected using test fuel with a sulfur content greater than 0.050
weight percent to determine compliance with the Tier 1 PM standards,
unless EPA adjusts the PM measurement using the equation specified in
paragraph (d)(2) of this section.

57004, Oct. 23, 1998]
Sec. 89.120 Compliance with emission standards.
(a) If all test engines representing an engine family have emissions
less than or equal to each emission standard, that family complies with
the emission standards.
(b) If any test engine representing an engine family has emissions
greater than each emission standard, that family will be deemed not in
compliance with the emission standard(s).
(c) For each nonroad engine family, except Tier 1 engine families
with rated power at or above 37 kW that do not employ aftertreatment, a
deterioration factor must be determined and applied.
(1) The applicable exhaust emission standards (or family emission
limits, as appropriate) for nonroad compression-ignition engines apply
to the emissions of engines for their useful life.
(2) [Reserved]
(3)(i) This paragraph (c)(3) describes the procedure for determining
compliance of an engine with emission standards (or family emission
limits, as appropriate), based on deterioration factors supplied by the
manufacturer. The NMHC + NOX deterioration factors shall be
established based on the sum of the pollutants, except as provided in
paragraph (c)(3)(iv) of this section. When establishing deterioration
factors for NMHC + NOX. a negative deterioration (emissions
decrease from the official emissions test result) for one pollutant may
not offset deterioration of the other pollutant.
(ii) Separate emission deterioration factors, determined by the
manufacturer according to the requirements of Sec. 89.118, shall be
provided in the certification application for each engine-system
combination. Separate deterioration factors shall be established for
each regulated pollutant, except that a combined NMHC + NOX
deterioration factor shall be established for compression-ignition
nonroad engines not utilizing aftertreatment technology. For smoke
testing, separate deterioration factors shall also be established for
the acceleration mode (designated as ``A''), the lugging mode
(designated as ``B''), and peak opacity (designated as ``C'').
(iii) Compression-ignition nonroad engines not utilizing
aftertreatment technology (e.g., particulate traps). For CO, NMHC +
NOX. and particulate, the official exhaust emission results
for each emission data engine at the selected test point shall be
adjusted by addition of the appropriate deterioration factor. However,
if the deterioration factor supplied by the manufacturer is less than
zero, it shall be zero for the purposes of this paragraph (c)(3)(iii).
(iv) Compression-ignition nonroad engines utilizing aftertreatment
technology (e.g., particulate traps). For CO, NMHC + NOX. and
particulate, the official exhaust emission results for each emission
data engine at the selected test point shall be adjusted by
multiplication by the appropriate deterioration factor. Separate NMHC
and NOX deterioration factors shall be applied to the results
for these pollutants prior to combining the results. If the
deterioration factor supplied by the manufacturer is less than one, it
shall be one for the purposes of this paragraph (c)(3)(iv).
(v) For acceleration smoke (``A''), lugging smoke (``B''), and peak
opacity (``C''), the official exhaust emission results for each emission
data engine at the selected test point shall be adjusted by the addition
of the appropriate deterioration factor. However if the deterioration
supplied by the manufacturer is less than zero, it shall be zero for the
purposes of this paragraph (c)(3)(v).
(vi) The emission values to compare with the standards (or family
emission
[[Page 63]]
limits, as appropriate) shall be the adjusted emission values of
paragraphs (c)(3)(iii) through (v) of this section, rounded to the same
number of significant figures as contained in the applicable standard in
accordance with ASTM E29-93a, for each emission data engine. This
procedure has been incorporated by reference at Sec. 89.6.
(4) Every test engine of an engine family must comply with all
applicable standards (or family emission limits, as appropriate), as
determined in paragraph (c)(3)(vi) of this section, before any engine in
that family will be certified.
(d) For engine families included in the averaging, banking, and
trading program, the families' emission limits (FELs) are used in lieu
of the applicable federal emission standard.
(e) For the purposes of setting an NMHC + NOX
certification level or FEL, one of the following options shall be used
for the determination of NMHC for an engine family. The manufacturer
must declare which option is used in its application for certification
of that engine family.
(1) The manufacturer may assume that up to two percent of the
measured THC is methane (NMHC = 0.98 x THC).
(2) The manufacturer may measure NMHC emissions using a method
approved by the Administrator prior to the start of testing. This option
allows the determination of NMHC emissions by subtracting measured
methane emissions from measured THC emissions.

for certificate, information obtained from any inspection, and such
other information as the Administrator may require, the Administrator
determines that the application is complete and that the engine family
meets the requirements of this part and the Clean Air Act, the
Administrator shall issue a certificate of conformity.
(b) If, after a review of the information described in paragraph (a)
of this section, the Administrator determines that the requirements of
this part and the Clean Air Act have not been met, the Administrator
will deny certification. The Administrator must give a written
explanation when certification is denied. The manufacturer may request a
hearing on a denial.

Sec. 89.123 Amending the application and certificate of conformity.
(a) The manufacturer of nonroad compression-ignition engines must
notify the Administrator when changes to information required to be
described in the application for certification are to be made to a
product line covered by a certificate of conformity. This notification
must include a request to amend the application or the existing
certificate of conformity. Except as provided in paragraph (e) of this
section, the manufacturer shall not make said changes or produce said
engines prior to receiving approval from EPA.
(b) A manufacturer's request to amend the application or the
existing certificate of conformity shall include the following
information:
(1) A full description of the change to be made in production or of
the engine to be added;
(2) Engineering evaluations or data showing that engines as modified
or added will comply with all applicable emission standards; and
(3) A determination whether the manufacturer's original test fleet
selection is still appropriate, and if the original test fleet selection
is determined not to be appropriate, proposed test fleet selection(s)
representing the engines changed or added which would have been required
if the engines had been included in the original application for
certification.
(c) The Administrator may require the manufacturer to perform tests
on
[[Page 64]]
the engine representing the engine to be added or changed.
(d) Decision by Administrator. (1) Based on the description of the
proposed amendment and data derived from such testing as the
Administrator may require or conduct, the Administrator will determine
whether the proposed change or addition would still be covered by the
certificate of conformity then in effect.
(2) If the Administrator determines that the change or new engine(s)
meets the requirements of this subpart and the Act, the appropriate
certificate of conformity is amended.
(3) If the Administrator determines that the changed or new
engine(s) does not meet the requirements of this subpart and the Act,
the certificate of conformity will not be amended. The Administrator
shall provide a written explanation to the manufacturer of the decision
not to amend the certificate. The manufacturer may request a hearing on
a denial.
(e) A manufacturer may make changes in or additions to production
engines concurrently with notifying the Administrator as required by
paragraph (a) of this section, if the manufacturer complies with the
following requirements:
(1) In addition to the information required in paragraph (b) of this
section, the manufacturer must supply supporting documentation, test
data, and engineering evaluations as appropriate to demonstrate that all
affected engines will still meet applicable emission standards.
(2) If, after a review, the Administrator determines additional
testing is required, the manufacturer must provide required test data
within 30 days or cease production of the affected engines.
(3) If the Administrator determines that the affected engines do not
meet applicable requirements, the Administrator will notify the
manufacturer to cease production of the affected engines and to recall
and correct at no expense to the owner all affected engines previously
produced.
(4) Election to produce engines under this paragraph will be deemed
to be a consent to recall all engines which the Administrator determines
do not meet applicable standards and to cause such nonconformity to be
remedied at no expense to the owner.

Sec. 89.126 Denial, revocation of certificate of conformity.
(a) If, after review of the manufacturer's application, request for
certification, information obtained from any inspection, and any other
information the Administrator may require, the Administrator determines
that one or more test engines do not meet applicable standards (or
family emission limits, as appropriate), then the Administrator will
notify the manufacturer in writing, setting forth the basis for this
determination.
(b) Notwithstanding the fact that engines described in the
application may comply with all other requirements of this subpart, the
Administrator may deny the issuance of, suspend, or revoke a previously
issued certificate of conformity if the Administrator finds any one of
the following infractions to be substantial:
(1) The manufacturer submits false or incomplete information;
(2) The manufacturer denies an EPA enforcement officer or EPA
authorized representative the opportunity to conduct authorized
inspections;
(3) The manufacturer fails to supply requested information or amend
its application to include all engines being produced;

Sec. 89.129 Right of entry.
(a) Any manufacturer who has applied for certification of a new
engine or engine family subject to certification testing under this
subpart shall admit or cause to be admitted to any of the following
facilities during operating hours any EPA enforcement officer or EPA
authorized representative on presentation of credentials.
(1) Any facility where any such certification testing or any
procedures or activities connected with such certification testing are
or were performed;
(2) Any facility where any new engine which is being, was, or is to
be tested is present;
(3) Any facility where any construction process or assembly process
used in the modification or buildup of such an engine into a
certification engine is taking place or has taken place; and
(4) Any facility where any record or other document relating to any
of the above is located.
(b) Upon admission to any facility referred to in paragraph (a)(1)
of this section, any EPA enforcement officer or EPA authorized
representative shall be allowed:
(1) To inspect and monitor any part or aspect of such procedures,
activities, and testing facilities, including, but not limited to,
monitoring engine preconditioning, emission tests and service
accumulation, maintenance, and engine storage procedures, and to verify
correlation or calibration of test equipment;
(2) To inspect and make copies of any such records, designs, or
other documents; and
(3) To inspect and photograph any part or aspect of any such
certification engine and any components to be used in the construction
thereof.
(c) To allow the Administrator to determine whether production
engines conform in all material respects to the design specifications
applicable to those engines, as described in the application for
certification for which a certificate of conformity has been issued, any
manufacturer shall admit any EPA enforcement officer or EPA authorized
representative on presentation of credentials to:
(1) Any facility where any document, design, or procedure relating
to the translation of the design and construction of engines and
emission-related components described in the application for
certification or used for certification testing into production engines
is located or carried on; and
[[Page 68]]
(2) Any facility where any engines to be introduced into commerce
are manufactured or assembled.
(d) On admission to any such facility referred to in paragraph (c)
of this section, any EPA enforcement officer or EPA authorized
representative shall be allowed:
(1) To inspect and monitor any aspects of such manufacture or
assembly and other procedures;
(2) To inspect and make copies of any such records, documents or
designs; and
(3) To inspect and photograph any part or aspect of any such new
engines and any component used in the assembly thereof that are
reasonably related to the purpose of his or her entry.
(e) Any EPA enforcement officer or EPA authorized representative
shall be furnished by those in charge of a facility being inspected with
such reasonable assistance as he or she may request to help the
enforcement officer or authorized representative discharge any function
listed in this paragraph. Each applicant for or recipient of
certification is required to cause those in charge of a facility
operated for its benefit to furnish such reasonable assistance without
charge to EPA whether or not the applicant controls the facility.
(1) Reasonable assistance includes, but is not limited to, clerical,
copying, interpretation and translation services; the making available
on request of personnel of the facility being inspected during their
working hours to inform the EPA enforcement officer or EPA authorized
representative of how the facility operates and to answer the officer's
questions; and the performance on request of emission tests on any
engine which is being, has been, or will be used for certification
testing. Such tests shall be nondestructive, but may require appropriate
service accumulation.
(2) A manufacturer may be compelled to cause any employee at a
facility being inspected to appear before an EPA enforcement officer or
EPA authorized representative. The request for the employee's appearance
shall be in writing, signed by the Assistant Administrator for Air and
Radiation, and served on the manufacturer. Any employee who has been
instructed by the manufacturer to appear will be entitled to be
accompanied, represented, and advised by counsel.
(f) The duty to admit or cause to be admitted any EPA enforcement
officer or EPA authorized representative applies whether or not the
applicant owns or controls the facility in question and applies both to
domestic and to foreign manufacturers and facilities. EPA will not
attempt to make any inspections which it has been informed that local
law forbids. However, if local law makes it impossible to do what is
necessary to ensure the accuracy of data generated at a facility, no
informed judgment that an engine is certifiable or is covered by a
certificate can properly be based on those data. It is the
responsibility of the manufacturer to locate its testing and
manufacturing facilities in jurisdictions where this situation will not
arise.
(g) Any entry without 24 hours prior written or oral notification to
the affected manufacturer shall be authorized in writing by the
Assistant Administrator for Enforcement.

Subpart C_Averaging, Banking, and Trading Provisions
Sec. 89.201 Applicability.
Nonroad compression-ignition engines subject to the provisions of
subpart A of this part are eligible to participate in the averaging,
banking, and trading program described in this subpart. To the extent
specified in 40 CFR part 60, subpart IIII, stationary engines certified
under this part and subject to the standards of 40 CFR part 60, subpart
IIII, may participate in the averaging, banking, and trading program
described in this subpart.

[[Page 69]]
Sec. 89.202 Definitions.
The definitions in subpart A of this part apply to this subpart. The
following definitions also apply to this subpart:
Averaging for nonroad engines means the exchange of emission credits
among engine families within a given manufacturer's product line.
Banking means the retention of nonroad engine emission credits by
the manufacturer generating the emission credits for use in future model
year averaging or trading as permitted by these regulations.
Emission credits represent the amount of emission reduction or
exceedance, by a nonroad engine family, below or above the emission
standard, respectively. Emission reductions below the standard are
considered as ``positive credits,'' while emission exceedances above the
standard are considered as ``negative credits.'' In addition,
``projected credits'' refer to emission credits based on the projected
applicable production/sales volume of the engine family. ``Reserved
credits'' are emission credits generated within a model year waiting to
be reported to EPA at the end of the model year. ``Actual credits''
refer to emission credits based on actual applicable production/sales
volume as contained in the end-of-year reports submitted to EPA. Some or
all of these credits may be revoked if EPA review of the end-of-year
reports or any subsequent audit action(s) uncovers problems or errors.
Trading means the exchange of nonroad engine emission credits
between manufacturers.

Sec. 89.203 General provisions.
(a) The averaging, banking, and trading programs for NOX.
NMHC+NOX. and PM emissions from eligible nonroad engines are
described in this subpart. Participation in these programs is voluntary.
(b) Requirements for Tier 1 engines rated at or above 37 kW. (1) A
nonroad engine family is eligible to participate in the averaging,
banking, and trading program for NOX emissions and the
banking and trading program for PM emissions if it is subject to
regulation under subpart B of this part with certain exceptions
specified in paragraph (b)(2) of this section. No averaging, banking,
and trading program is available for meeting the Tier 1 HC, CO, or smoke
emission standards specified in subpart B of this part. No averaging
program is available for meeting the Tier 1 PM emission standards
specified in subpart B of this part.
(2) Nonroad engines may not participate in the averaging, banking,
and trading programs if they are exported or are sold as Blue Sky Series
engines as described in Sec. 89.112(f). Nonroad engines certified on a
special test procedure under Sec. 89.114(a), may not participate in the
averaging, banking and trading programs unless the manufacturer has
requested that the engines be included in the averaging, banking, and
trading programs at the time the request for the special test procedure
is made and has been granted approval by the Administrator for inclusion
in the averaging, banking, and trading programs.
(3) A manufacturer may certify one or more nonroad engine families
at NOX family emission limits (FELs) above or below the Tier
1 NOX emission standard, provided the summation of the
manufacturer's projected balance of all NOX credit
transactions in a given model year is greater than or equal to zero, as
determined under Sec. 89.207(a). A manufacturer may certify one or more
nonroad engine families at PM FELs below the Tier 2 PM emission standard
that will be applicable to those engine families.
(i) FELs for NOX may not exceed the Tier 1 upper limit
specified in Sec. 89.112(d).
(ii) An engine family certified to an FEL is subject to all
provisions specified in this part, except that the applicable FEL
replaces the emission standard for the family participating in the
averaging, banking, and trading program.
(iii) A manufacturer of an engine family with a NOX FEL
exceeding the Tier 1 NOX emission standard must obtain
NOX emission credits sufficient to address the associated
credit shortfall via averaging, banking, or trading.
[[Page 70]]
(iv) An engine family with a NOX FEL below the applicable
Tier 1 standard may generate emission credits for averaging, banking,
trading, or a combination thereof. An engine family with a PM FEL below
the Tier 2 standard that will be applicable to that engine family may
generate emission credits for banking, trading, or a combination
thereof. Emission credits may not be used to offset an engine family's
emissions that exceed its applicable FEL. Credits may not be used to
remedy nonconformity determined by a Selective Enforcement Audit (SEA)
or by recall (in-use) testing. However, in the case of an SEA failure,
credits may be used to allow subsequent production of engines for the
family in question if the manufacturer elects to recertify to a higher
FEL.
(4) NOX credits generated in a given model year may be
used to address credit shortfalls with other engines during that model
year or in any subsequent model year except as noted under paragraph
(b)(5)(ii) of this section. PM credits may be used to address credit
shortfalls with Tier 2 and later engines greater than or equal to 37 kW
and Tier 1 and later engines less than 37 kW and greater than or equal
to 19 kW. Credits generated in one model year may not be used for prior
model years.
(5) The following provisions apply to the use of Tier 1
NOX credits for showing compliance with the Tier 2 or Tier 3
NMHC+NOX standards.
(i) A manufacturer may use NOX credits from engines
subject to the Tier 1 NOX standard to address
NMHC+NOX credit shortfalls with engines in the same averaging
set subject to Tier 1 NMHC+NOX or Tier 2 NMHC+NOX
emission standards.
(ii) A manufacturer may not use NOX credits from engines
subject to the Tier 1 standards to address NMHC+NOX credit
shortfalls with engines subject to the Tier 3 NMHC+NOX
emission standards.
(c) Requirements for Tier 2 and later engines rated at or above 37
kW and Tier 1 and later engines rated under 37 kW. (1) A nonroad engine
family is eligible to participate in the averaging, banking, and trading
programs for NMHC+NOX emissions and PM emissions if it is
subject to regulation under subpart B of this part with certain
exceptions specified in paragraph (c)(2) of this section. No averaging,
banking, and trading program is available for meeting the CO or smoke
emission standards specified in subpart B of this part.
(2) Nonroad engines may not participate in the averaging, banking,
and trading programs if they are exported or are sold as Blue Sky Series
engines as described in Sec. 89.112(f). Nonroad engines certified on a
special test procedure under Sec. 89.114(a), may not participate in the
averaging, banking and trading programs unless the manufacturer has
requested that the engines be included in the averaging, banking, and
trading programs at the time the request for the special test procedure
is made and has been granted approval by the Administrator for inclusion
in the averaging, banking, and trading programs.
(3)(i) A manufacturer may certify one or more nonroad engine
families at FELs above or below the applicable NMHC+NOX
emission standard and PM emission standard, provided the summation of
the manufacturer's projected balance of all NMHC+NOX credit
transactions and the summation of the manufacturer's projected balance
of all PM credit transactions in a given model year in a given averaging
set is greater than or equal to zero, as determined under Sec.
89.207(b).
(A) FELs for NMHC+NOX and FELs for PM may not exceed the
upper limits specified in Sec. 89.112(d).
(B) An engine family certified to an FEL is subject to all
provisions specified in this part, except that the applicable FEL
replaces the emission standard for the family participating in the
averaging, banking, and trading program.
(C) A manufacturer of an engine family with an FEL exceeding the
applicable emission standard must obtain emission credits sufficient to
address the associated credit shortfall via averaging, banking, or
trading, within the restrictions described in Sec. 89.204(c) and Sec.
89.206(b)(4).
(D) An engine family with an FEL below the applicable standard may
generate emission credits for averaging, banking, trading, or a
combination
[[Page 71]]
thereof. Emission credits may not be used to offset an engine family's
emissions that exceed its applicable FEL. Credits may not be used to
remedy nonconformity determined by a Selective Enforcement Audit (SEA)
or by recall (in-use) testing. However, in the case of an SEA failure,
credits may be used to allow subsequent production of engines for the
family in question if the manufacturer elects to recertify to a higher
FEL.
(ii)(A) In lieu of generating credits under paragraph (c)(3)(i) of
this section, a manufacturer may certify one or more nonroad engine
families rated under 37 kW at family emission limits (FELs) above or
below the applicable NMHC+NOX emission standard and PM
emission standard. The summation of the manufacturer's projected balance
of all NMHC+NOX credit transactions and the summation of the
manufacturer's projected balance of all PM credit transactions in a
given model year, as determined under Sec. 89.207(b), are each allowed
to be less than zero. Separate calculations shall be required for the
following two categories of engines: engines rated under 19 kW and
engines rated at or above 19 kW and under 37 kW.
(B) For each calendar year a negative credit balance exists as of
December 31, a penalty equal to ten percent of the negative credit
balance as of December 31 of the calendar year shall be added to the
negative credit balance. The resulting negative credit balance shall be
carried into the next calendar year.
(C) For engines rated under 19 kW, a manufacturer will be allowed to
carry over a negative credit balance until December 31, 2003. For
engines rated at or above 19 kW and under 37 kW, a manufacturer will be
allowed to carry over a negative credit balance until December 31, 2002.
As of these dates, the summation of the manufacturer's projected balance
of all NMHC+NOX credit transactions and the summation of the
manufacturer's projected balance of all PM credit transactions must each
be greater than or equal to zero.
(D) FELs for NMHC+NOX and FELs for PM may not exceed the
upper limits specified in Sec. 89.112(d).
(E) An engine family certified to an FEL is subject to all
provisions specified in this part, except that the applicable
NMHC+NOX FEL or PM FEL replaces the NMHC+NOX
emission standard or PM emission standard for the family participating
in the averaging and banking program.
(F) A manufacturer of an engine family with an FEL exceeding the
applicable emission standard must obtain emission credits sufficient to
address the associated credit shortfall via averaging or banking. The
exchange of emission credits generated under this program with other
nonroad engine manufacturers in trading is not allowed.
(G) An engine family with an FEL below the applicable standard may
generate emission credits for averaging, banking, or a combination
thereof. Emission credits may not be used to offset an engine family's
emissions that exceed its applicable FEL. Credits may not be used to
remedy nonconformity determined by a Selective Enforcement Audit (SEA)
or by recall (in-use) testing. However, in the case of an SEA failure,
credits may be used to allow subsequent production of engines for the
family in question if the manufacturer elects to recertify to a higher
FEL.
(4)(i) Except as noted in paragraphs (c)(4)(ii), (c)(4)(iii), and
(c)(4)(iv) of this section, credits generated in a given model year may
be used during that model year or used in any subsequent model year.
Except as allowed under paragraph (c)(3)(ii) of this section, credits
generated in one model year may not be used for prior model years.
(ii) Credits generated from engines rated under 19 kW prior to the
implementation date of the applicable Tier 2 standards, shall expire on
December 31, 2007.
(iii) Credits generated from engines rated under 19 kW under the
provisions of paragraph (c)(3)(ii) shall expire on December 31, 2003.
(iv) Credits generated from engines rated at or above 19 kW and
under 37 kW under the provisions of paragraph (c)(3)(ii) of this section
shall expire on December 31, 2002.
(5) Except as provided in paragraph (b)(3) of this section, engine
families
[[Page 72]]
may not generate credits for one pollutant while also using credits for
another pollutant in the same model year.
(6) Model year 2008 and 2009 engines rated under 8 kW that are
allowed to certify under this part because they meet the criteria in 40
CFR 1039.101(c) may not generate emission credits.
(d) Manufacturers must demonstrate compliance under the averaging,
banking, and trading programs for a particular model year within 270
days of the end of the model year. Except as allowed under paragraph
(c)(3)(ii) of this section, manufacturers that have certified engine

Sec. 89.204 Averaging.
(a) Requirements for Tier 1 engines rated at or above 37 kW. A
manufacturer may use averaging to offset an emission exceedance of a
nonroad engine family caused by a NOX FEL above the
applicable emission standard. NOX credits used in averaging
may be obtained from credits generated by another engine family in the
same model year, credits banked in a previous model year, or credits
obtained through trading.
(b) Requirements for Tier 2 and later engines rated at or above 37
kW and Tier 1 and later engines rated under 37 kW. A manufacturer may
use averaging to offset an emission exceedance of a nonroad engine
family caused by an NMHC+;NOX FEL or a PM FEL above the
applicable emission standard. Credits used in averaging may be obtained
from credits generated by another engine family in the same model year,
credits banked in previous model years that have not expired, or credits
obtained through trading. The use of credits shall be within the
restrictions described in paragraph (c) of this section, Sec.
89.206(b)(4) and Sec. 89.203(b)(5)(ii).
(c) Averaging sets for emission credits. The averaging and trading
of NOX emission credits, NMHC + NOX emission
credits, and PM emissions credits will only be allowed between engine
families in the same averaging set. The averaging sets for the averaging
and trading of NOX emission credits, NMHC + NOX
emission credits, and PM emission credits for nonroad engines are
defined as follows:
(1) Eligible engines rated at or above 19 kW, other than marine
diesel engines, constitute an averaging set.
(2) Eligible engines rated under 19 kW, other than marine diesel
engines, constitute an averaging set.
(3) Marine diesel engines rated at or above 19 kW constitute an
averaging set. Emission credits generated from marine diesel engines
rated at or above 19 kW may be used to address credit shortfalls for
eligible engines rated at or above 19 kW other than marine diesel
engines.
(4) Marine diesel engines rated under 19 kW constitute an averaging
set. Emission credits generated from marine diesel engines rated under
19 kW may be used to address credit shortfalls for eligible engines
rated under 19 kW other than marine diesel engines.

Sec. 89.207 Credit calculation.
(a) Requirements for calculating NOX credits from Tier 1
engines rated at or above 37 kW. (1) For each participating engine
family, emission credits (positive or negative) are to be calculated
according to one of the following equations and rounded, in accordance
with ASTM E29-93a, to the nearest one-hundredth of a megagram (Mg). This
ASTM procedure has been incorporated by reference (see Sec. 89.6).
Consistent units are to be used throughout the equation.
(i) For determining credit availability from all engine families
generating credits: Emission credits = (Std-FEL) x (Volume) x (AvgPR) x
(UL) x (Adjustment) x (10-6)
(ii) For determining credit usage for all engine families requiring
credits to offset emissions in excess of the standard:
Emission credits = (Std-FEL) x (Volume) x (AvgPR) x (UL) x
(10-6)
Where:
[[Page 74]]
Std = the applicable Tier 1 NOX nonroad engine emission
standard, in grams per kilowatt-hour.
FEL = the NOX family emission limit for the engine family in
grams per kilowatt-hour.
Volume = the number of nonroad engines eligible to participate in the
averaging, banking, and trading program within the given engine family
during the model year. Engines sold to equipment or vehicle
manufacturers under the provisions of Sec. 89.102(g) shall not be
included in this number. Quarterly production projections are used for
initial certification. Actual applicable production/sales volume is used
for end-of-year compliance determination.
AvgPR = the average power rating of all of the configurations within an
engine family, calculated on a sales-weighted basis, in kilowatts.
UL = the useful life for the engine family, in hours.
Adjustment = a one-time adjustment, as specified in paragraph (a)(2) of
this section, to be applied to Tier 1 NOX credits to be
banked or traded for determining compliance with the Tier 1
NOX standards or Tier 2 NOX+NMHC standards
specified in subpart B of this part. Banked credits traded in a
subsequent model year will not be subject to an additional adjustment.
Banked credits used in a subsequent model year's averaging program will
not have the adjustment restored.
(2) If an engine family is certified to a NOX FEL of 8.0
g/kW-hr or less, an Adjustment value of 1.0 shall be used in the credit
generation calculation described in paragraph (a)(1)(i) of this section.
If an engine family is certified to a NOX FEL above 8.0 g/kW-
hr, an Adjustment value of 0.65 shall be used in the credit generation
calculation described in paragraph (a)(1)(i) of this section. If the
credits are to be used by the credit-generating manufacturer for
averaging purposes in the same model year in which they are generated,
an Adjustment value of 1.0 shall be used for all engines regardless of
the level of the NOX FEL. If the credits are to be banked by
the credit-generating manufacturer and used in a subsequent model year
for another Tier 1 engine family, an Adjustment value of 1.0 shall be
used for all engines regardless of the level of the NOX FEL.
(b) Requirements for calculating NMHC + NOX Credits from
Tier 2 and later engines rated at or above 37 kW and Tier 1 and later
engines rated under 37 kW and PM credits from all engines. (1) For each

generating credits:
Emission credits = (Std-FEL) x (Volume) x (AvgPR) x (UL) x
(10-6)
(ii) For determining credit usage for all engine families requiring
credits to offset emissions in excess of the standard:
Emission credits = (Std-FEL) x (Volume) x (AvgPR) x (UL) x
(10-6)
Where:
Std = the current and applicable nonroad engine emission standard, in
grams per kilowatt-hour, except for PM calculations where it is the
applicable nonroad engine Tier 2 PM emission standard, and except for
engines rated under 19 kW where it is the applicable nonroad engine Tier
2 emission standard, in grams per kilowatt-hour. (Engines rated under 19
kW participating in the averaging and banking program provisions of
Sec. 89.203(c)(3)(ii) shall use the Tier 1 standard for credit
calculations.)
FEL = the family emission limit for the engine family in grams per
kilowatt-hour.
Volume = the number of nonroad engines eligible to participate in the
averaging, banking, and trading program within the given engine family
during the model year. Engines sold to equipment or vehicle
manufacturers under the provisions of Sec. 89.102(g) shall not be
included in this number. Quarterly production projections are used for
initial certification. Actual applicable production/sales volume is used

Sec. 89.310 Analyzer accuracy and specifications.
(a) Measurement accuracy--general. The analyzers must have a
measuring range which allows them to measure the concentrations of the
exhaust gas sample pollutants with the accuracies shown in Table 3 in
Appendix A of this subpart.
(1) Response time. As necessary, measure and account for the
response time of the analyzer.
(2) Precision. The precision of the analyzer must be, at worst,
1 percent of full-scale concentration for each
range used at or above 100 ppm (or ppmC) or 2
percent for each range used below 100 ppm (or ppmC). The precision is
defined as 2.5 times the standard deviation(s) of 10 repetitive
responses to a given calibration or span gas.
(3) Noise. The analyzer peak-to-peak response to zero and
calibration or span gases over any 10-second period must not exceed 2
percent of full-scale chart deflection on all ranges used.
(4) Zero drift. The analyzer zero-response drift during a 1-hour
period must be less than 2 percent of full-scale chart deflection on the
lowest range used. The zero-response is defined as the mean response
including noise to a zero-gas during a 30-second time interval.
(5) Span drift. The analyzer span drift during a 1-hour period must
be less than 2 percent of full-scale chart deflection on the lowest
range used. The analyzer span is defined as the difference between the
span-response and the zero-response. The span-response is defined as the
mean response including noise to a span gas during a 30-second time
interval.
(b) Operating procedure for analyzers and sampling system. Follow
the start-up and operating instructions of the instrument manufacturer.
Adhere to the minimum requirements given in Sec. 89.314 to Sec.
89.323.
(c) Emission measurement accuracy--Bag sampling. (1) Good
engineering practice dictates that exhaust emission sample analyzer
readings below 15 percent of full-scale chart deflection should
generally not be used.
(2) Some high resolution read-out systems, such as computers, data
loggers, and so forth, can provide sufficient accuracy and resolution
below 15 percent of full scale. Such systems may be used provided that
additional calibrations of at least 4 non-zero nominally equally spaced
points, using good engineering judgement, below 15 percent of full scale
are made to ensure the accuracy of the calibration curves. If a gas
divider is used, the gas divider must conform to the accuracy
requirements specified in Sec. 89.312(c). The procedure in paragraph
(c)(3) of this section may be used for calibration below 15 percent of
full scale.
(3) The following procedure shall be followed:
(i) Span the analyzer using a calibration gas meeting the accuracy
requirements of Sec. 89.312(c), within the operating range of the
analyzer, and at least 90% of full scale.
(ii) Generate a calibration over the full concentration range at a
minimum of 6, approximately equally spaced, points (e.g. 15, 30, 45, 60,
75, and 90 percent of the range of concentrations provided by the gas
divider). If a gas divider or blender is being used to calibrate the
analyzer and the requirements of paragraph (c)(2) of this section are
met, verify that a second calibration gas between 10 and 20 percent of
full scale can be named within 2 percent of its certified concentration.
(iii) If a gas divider or blender is being used to calibrate the
analyzer, input the value of a second calibration gas (a span gas may be
used for the CO2 analyzer) having a named concentration between 10 and
20 percent of full scale. This gas shall be included on the calibration
curve. Continue adding calibration points by dividing this gas
[[Page 81]]
until the requirements of paragraph (c)(2) of this section are met.
(iv) Fit a calibration curve per Sec. 89.319 through Sec. 89.322
for the full scale range of the analyzer using the calibration data
obtained with both calibration gases.
(d) Emission measurement accuracy--continuous sampling. Analyzers
used for continuous analysis must be operated such that the measured
concentration falls between 15 and 100 percent of full-scale chart
deflection. Exceptions to these limits are:
(1) The analyzer's response may be less than 15 percent or more than
100 percent of full scale if automatic range change circuitry is used
and the limits for range changes are between 15 and 100 percent of full-
scale chart deflection;
(2) The analyzer's response may be less than 15 percent of full
scale if:
(i) Alternative (c)(2) of this section is used to ensure that the
accuracy of the calibration curve is maintained below 15 percent; or
(ii) The full-scale value of the range is 155 ppm (or ppmC) or less.

instrumentation meet the specifications in Table 3 in appendix A of this
subpart.

shall be available:
(i) C3H8 and purified synthetic air ;

percent of the NO content);
(v) CO2 and purified nitrogen.
(3) The true concentration of a span gas must be within 2 percent of the NIST gas standard. The true
concentration of a calibration gas must be within 1 percent of the NIST gas standard. The use of precision
blending devices (gas dividers) to obtain the required calibration gas
concentrations is acceptable, provided that the blended gases are
accurate to within 1.5
[[Page 82]]
percent of NIST gas standards, or other gas standards which have been
approved by the Administrator. This accuracy implies that primary gases
used (or blending) must be ``named'' to an accuracy of at least 1 percent, traceable to NIST or other approved gas
standards. All concentrations of calibration gas shall be given on a
volume basis (volume percent or volume ppm).
(4) The gas concentrations used for calibration and span may also be
obtained by means of a gas divider, either diluting with purified
N2 or diluting with purified synthetic air. The accuracy of
the mixing device must be such that the concentration of the diluted
gases may be determined to within 2 percent.

ppmC 75 ppmC hydrocarbon. The three oxygen
interference gases shall contain 21% 1%
O2, 10% 1% O2, and 5%

of total hydrocarbons plus impurities or by dynamic blending. Nitrogen
shall be the predominant diluent with the balance oxygen.
(e) Fuel for the FID shall be a blend of 40 percent 2 percent hydrogen with the balance being helium. The
mixture shall contain less than 1 ppm equivalent carbon response; 98 to
100 percent hydrogen fuel may be used with advance approval of the
Administrator.
(f) Hydrocarbon analyzer burner air. The concentration of oxygen for
raw sampling must be within 1 mole percent of the oxygen concentration
of the burner air used in the latest oxygen interference check
(%O2I). If the difference in oxygen concentration is greater
than 1 mole percent, then the oxygen interference must be checked and,
if necessary, the analyzer adjusted to meet the %O2I
requirements. The burner air must contain less than 2 ppmC hydrocarbon.
(g) Gases for the methane analyzer shall be single blends of methane
using air as the diluent.

recommendations of the manufacturer. If not specified, a minimum of two
hours shall be allowed for warming up the analyzers.
(b) NDIR and HFID analyzer. The NDIR analyzer shall be tuned and
maintained according to the instrument manufacturer's instructions. The
combustion flame of the HFID analyzer shall be optimized in order to
meet the specifications in Sec. 89.319(b)(2).

Each operating range used during the test shall be checked prior to
and after each test in accordance with the following procedure. (A
chronic need for parameter adjustment can indicate a need for instrument
maintenance.):
(a) The calibration is checked by using a zero gas and a span gas
whose nominal value is between 75 percent and 100 percent of full-scale,
inclusive, of the measuring range.
(b) After the end of the final mode, a zero gas and the same span
gas will be used for rechecking. As an option, the zero and span may be
rechecked at the end of each mode or each test segment. The analysis
will be considered acceptable if the difference between the two
measuring results is less than 2 percent of full scale.

(a) Prior to initial use and after major repairs verify that each
analyzer complies with the specifications given in Table 3 in appendix A

(b) If a stainless steel NO2 to NO converter is used,
condition all new or replacement converters. The conditioning consists
of either purging the converter with air for a minimum of 4 hours or
until the converter efficiency is greater than 90 percent. The converter
must be at operational temperature while purging. Do not use this
procedure prior to checking converter efficiency on in-use converters.

(a) Vacuum side leak check. (1) Any location within the analysis
system where a vacuum leak could affect the test results must be
checked.
(2) The maximum allowable leakage rate on the vacuum side is 0.5
percent of the in-use flow rate for the portion of the system being
checked. The analyzer flows and bypass flows may be used to estimate the
in-use flow rates.

Sec. 89.317 NOX converter check.
(a) Prior to its introduction into service, and monthly thereafter,
the chemiluminescent oxides of nitrogen analyzer shall be checked for
NO2 to NO converter efficiency. Figure 2 in appendix B of
this subpart is a reference for the following paragraphs.
(b) Follow good engineering practices for instrument start-up and
operation. Adjust the analyzer to optimize performance.
(c) Zero the oxides of nitrogen analyzer with zero-grade air or
zero-grade nitrogen.
(d) Connect the outlet of the NOX generator to the sample
inlet of the oxides of nitrogen analyzer which has been set to the most
common operating range.
(e) Introduce into the NOX generator analyzer-system an
NO-in-nitrogen (N2) mixture with an NO concentration equal to
approximately 80 percent of the most common operating range. The
NO2 content of the gas mixture shall be less than 5 percent
of the NO concentration.
(f) With the oxides of nitrogen analyzer in the NO mode, record the
concentration of NO indicated by the analyzer.
(g) Turn on the NOX generator O2 (or air)
supply and adjust the O2 (or air) flow rate so that the NO
indicated by the analyzer is about 10 percent less than indicated in
paragraph (f) of this section. Record the concentration of NO in this
NO+O2 mixture.
(h) Switch the NOX generator to the generation mode and
adjust the generation rate so that the NO measured on the analyzer is 20
percent of that measured in paragraph (f) of this section. There must be
at least 10 percent unreacted NO at this point. Record the concentration
of residual NO.
(i) Switch the oxides of nitrogen analyzer to the NOX
mode and measure total NOX. Record this value.
(j) Switch off the NOX generator but maintain gas flow
through the system. The oxides of nitrogen analyzer will indicate the
NOX in the NO+O2 mixture. Record this value.
(k) Turn off the NOX generator O2 (or air)
supply. The analyzer will now indicate the NOX in the
original NO-in-N2 mixture. This value should be no more than
5 percent above the value indicated in paragraph (f) of this section.

Sec. 89.318 Analyzer interference checks.
(a) Gases present in the exhaust other than the one being analyzed
can interfere with the reading in several ways. Positive interference
occurs in NDIR and PMD instruments when the interfering gas gives the
same effect as
[[Page 84]]
the gas being measured, but to a lesser degree. Negative interference
occurs in NDIR instruments by the interfering gas broadening the
absorption band of the measured gas and in CLD instruments by the
interfering gas quenching the radiation. The interference checks
described in this section are to be made initially and after any major
repairs that could affect analyzer performance.
(b) CO analyzer water and CO2 interference checks. Prior
to its introduction into service and annually thereafter, the NDIR
carbon monoxide analyzer shall be checked for response to water vapor
and CO2.
(1) Follow good engineering practices for instrument start-up and
operation. Adjust the analyzer to optimize performance on the most
sensitive range to be used.
(2) Zero the carbon monoxide analyzer with either zero-grade air or
zero-grade nitrogen.
(3) Bubble a mixture of 3 percent CO2 in N2
through water at room temperature and record analyzer response.
(4) An analyzer response of more than 1 percent of full scale for
ranges above 300 ppm full scale or more than 3 ppm on ranges below 300
ppm full scale requires corrective action. (Use of conditioning columns
is one form of corrective action which may be taken.)
(c) NOX analyzer quench check. The two gases of concern
for CLD (and HCLD) analyzers are CO2 and water vapor. Quench
responses to these two gases are proportional to their concentrations
and, therefore, require test techniques to determine quench at the
highest expected concentrations experienced during testing.
(1) NOX analyzer CO2 quench check. A CO2 span
gas having a concentration of 80 percent to 100 percent of full scale of
the maximum operating range used during testing shall be passed through
the CO2 NDIR analyzer and the value recorded as a. It is
diluted approximately 50 percent with NO span gas and then passed
through the CO2 NDIR and CLD (or HCLD), with the
CO2 and NO values recorded as b and c respectively. The
CO2 shall then be shut off and only the NO span gas passed
through the CLD (or HCLD) and the NO value recorded as d. Percent
CO2 quench shall be calculated as follows and shall not
exceed 3 percent:
[GRAPHIC] [TIFF OMITTED] TR17JN94.001
Where:
a = Undiluted CO2 concentration (percent)
b = Diluted CO2 concentration (percent)
c = Diluted NO concentration (ppm)
d = Undiluted NO concentration (ppm)
(2) NOX analyzer water quench check. (i) This check
applies to wet measurements only. An NO span gas having a concentration
of 80 to 100 percent of full scale of a normal operating range shall be
passed through the CLD (or HCLD) and the response recorded as D. The NO
span gas shall then be bubbled through water at room temperature and
passed through the CLD (or HCLD) and the analyzer response recorded as
AR. Determine and record the bubbler absolute operating pressure and the
bubbler water temperature. (It is important that the NO span gas
contains minimal NO2 concentration for this check. No
allowance for absorption of NO2 in water has been made in the
following quench calculations. This test may be optionally run in the NO
mode to minimize the effect of any NO2 in the NO span gas.)
(ii) Calculations for water quench must consider dilution of the NO
span gas with water vapor and scaling of the water vapor concentration
of the mixture to that expected during testing. Determine the mixture's
saturated vapor pressure (designated as Pwb) that corresponds to the
bubbler water temperature. Calculate the water concentration (Z1,
percent) in the mixture by the following equation:
[[Page 85]]
[GRAPHIC] [TIFF OMITTED] TR17JN94.002
where
GP = analyzer operating pressure (Pa)
(iii) Calculate the expected dilute NO span gas and water vapor
mixture concentration (designated as D1) by the following equation:
[GRAPHIC] [TIFF OMITTED] TR17JN94.003
(iv)(A) The maximum raw or dilute exhaust water vapor concentration
expected during testing (designated as Wm) can be estimated from the
CO2 span gas (or as defined in the equation in this paragraph
and designated as A) criteria in paragraph (c)(1) of this section and
the assumption of a fuel atom H/C ratio of 1.8:1 as:
Wm(%)=0.9xA(%)
Where:
A = maximum CO2 concentration expected in the sample system during
testing.
(B) Percent water quench shall not exceed 3 percent and shall be
calculated by:

Sec. 89.319 Hydrocarbon analyzer calibration.
(a) The FID hydrocarbon analyzer shall receive the initial and
periodic calibration as described in this section. The HFID used with
petroleum-fueled diesel (compression-ignition) engines shall be operated
to a set point 5.5 [deg]C between 185 and 197
[deg]C.
(b) Initial and periodic optimization of detector response. Prior to
introduction into service and at least annually thereafter, adjust the
FID hydrocarbon analyzer for optimum hydrocarbon response as specified
in this paragraph. Alternate methods yielding equivalent results may be
used, if approved in advance by the Administrator.
(1) Follow good engineering practices for initial instrument start-
up and basic operating adjustment using the appropriate fuel (see Sec.
89.312(e)) and zero-grade air.
(2) Optimize the FID's response on the most common operating range.
The response is to be optimized with respect to fuel pressure or flow.
Efforts shall be made to minimize response variations to different
hydrocarbon species that are expected to be in the exhaust. Good
engineering judgment is to be used to trade off optimal FID response to
propane-in-air against reductions in relative responses to other
hydrocarbons. A good example of trading off response on propane for
relative responses to other hydrocarbon species is given in Society of
Automotive Engineers (SAE) Paper No. 770141, ``Optimization of Flame
Ionization Detector for Determination of Hydrocarbon in Diluted
Automotive Exhausts''; author Glenn D. Reschke. It is also required that
the response be set to optimum condition with respect to air flow and
sample flow. Heated Flame Ionization Detectors (HFIDs) must be at their
specified operating temperature. One of the following procedures is
required for FID or HFID optimization:
(i) The procedure outlined in Society of Automotive Engineers (SAE)
paper No. 770141, ``Optimization of a Flame Ionization Detector for
Determination of Hydrocarbon in Diluted Automotive Exhausts''; author,
Glenn D. Reschke. This procedure has been incorporated by reference at
Sec. 89.6.
(ii) The HFID optimization procedures outlined in 40 CFR part 1065,
subpart D.
(iii) Alternative procedures may be used if approved in advance by
the Administrator.
(iv) The procedures specified by the manufacturer of the FID or
HFID.
[[Page 86]]
(3) After the optimum flow rates have been determined, record them
for future reference.
(c) Initial and periodic calibration. Prior to introduction into
service, after any maintenance which could alter calibration, and
monthly thereafter, the FID or HFID hydrocarbon analyzer shall be
calibrated on all normally used instrument ranges using the steps in
this paragraph (c). Use the same flow rate and pressures as when
analyzing samples. Calibration gases shall be introduced directly at the
analyzer, unless the ``overflow'' calibration option of 40 CFR part
1065, subpart F, for the HFID is taken. New calibration curves need not
be generated each month if the existing curve can be verified as
continuing to meet the requirements of paragraph (c)(3) of this section.
(1) Adjust analyzer to optimize performance.
(2) Zero the hydrocarbon analyzer with zero-grade air.
(3) Calibrate on each used operating range with propane-in-air
(dilute or raw) or propane-in-nitrogen (raw) calibration gases having
nominal concentrations starting between 10-15 percent and increasing in
at least six incremental steps to 90 percent (e.g., 15, 30, 45, 60, 75,
and 90 percent of that range) of that range. The incremental steps are
to be spaced to represent good engineering practice. For each range
calibrated, if the deviation from a least-squares best-fit straight line
is 2 percent or less of the value at each data point, concentration
values may be calculated by use of a single calibration factor for that
range. If the deviation exceeds 2 percent at each non-zero data point
and within 0.3 percent of full scale on the zero,
the best-fit non-linear equation which represents the data to within
these limits shall be used to determine concentration.
(d) Oxygen interference optimization (required for raw). Choose a
range where the oxygen interference check gases will fall in the upper
50 percent. Conduct the test, as outlined in this paragraph, with the
oven temperature set as required by the instrument manufacturer. Oxygen
interference check gas specifications are found in Sec. 89.312(d).
(1) Zero the analyzer.
(2) Span the analyzer with the 21% oxygen interference gas specified
in Sec. 89.312(d).
(3) Recheck zero response. If it has changed more than 0.5 percent
of full scale repeat paragraphs (d)(1) and (d)(2) of this section to
correct problem.
(4) Introduce the 5 percent and 10 percent oxygen interference check
gases.
(5) Recheck the zero response. If it has changed more 1 percent of full scale, repeat the test.
(6) Calculate the percent of oxygen interference (designated as
percent O2I) for each mixture in paragraph (d)(4) of this
section.
percent O2I = ((B - C) x 100)/B
Where:
A = hydrocarbon concentration (ppmC) of the span gas used in paragraph
(d)(2) of this section.
B = hydrocarbon concentration (ppmC) of the oxygen interference check
gases used in paragraph (d)(4) of this section.
C = analyzer response (ppmC) = A/D; where
D = (percent of full-scale analyzer response due to A) x (percent of
full-scale analyzer response due to B)

N2 calibration gases having nominal concentrations starting
between 10 and 15 percent and increasing in at least six incremental
steps to 90 percent (e.g., 15, 30, 45, 60, 75, and 90 percent) of that
range. The incremental steps are to be spaced to represent good
engineering practice. For each range calibrated, if the deviation from a
least-squares best-fit straight line is 2 percent or less of the value
at each non-zero data point and within 0.3
percent of full scale on the zero, concentration values may be
calculated by use of a single calibration factor for that range. If the
deviation exceeds these limits, the best-fit non-linear equation which
represents the data to within these limits shall be used to determine
concentration.
(d) The initial and periodic interference, system check, and
calibration test procedures specified in 40 CFR part 1065 may be used in
lieu of the procedures specified in this section.

(1) Adjust analyzer to optimize performance.
(2) Zero the oxides of nitrogen analyzer with zero-grade air or
zero-grade nitrogen.
(3) Calibrate on each normally used operating range with NO-in-
N2 calibration gases with nominal concentrations starting at

engineering practice. For each range calibrated, if the deviation from a
least-squares best-fit straight line is 2 percent or less of the value
at each non-zero data point and within 0.3
percent of full scale on the zero, concentration values may be
calculated by use of a single calibration factor for that range. If the
deviation exceeds these limits, the best-fit non-linear equation which
represents the data to within these limits shall be used to determine
concentration.

practice. For each range calibrated, if the deviation from a least-
squares best-fit straight line is 2 percent or less of the value at each
non-zero data point and within 0.3 percent of
full scale on the zero, concentration values may be calculated by use of
a single calibration factor for that range. If the deviation exceeds
these limits, the best-fit non-linear equation which represents the data
to within these limits shall be used to determine concentration.

percent of full scale, repeat the steps given in paragraphs (b)(1) and
(b)(2) of this section.
(4) Record the response of calibration gases having nominal
concentrations starting between 10 and 15 percent and increasing in at
least six incremental steps to 90 percent of that range. The incremental
steps are to be spaced to represent good engineering practice.
(5) Generate a calibration curve. The calibration curve shall be of
fourth order or less, have five or fewer coefficients. If any range is
within 2 percent of being linear a linear calibration may be used.
Include zero as a data point. Compensation for known impurities in the
zero gas can be made to the zero-data point. The calibration curve must
fit the data points within 2 percent of point.

incremental steps are to be spaced to represent good engineering
practice. For each range calibrated, if the deviation from a least-
squares best-fit straight line is 2 percent or less of the value at each
non-zero data point and within 0.3 percent of
full scale on the zero, concentration values may be calculated by use of
a single calibration factor for that range. If the deviation exceeds
