PART 89_CONTROL OF EMISSIONS FROM NEW AND IN-USE NONROAD
COMPRESSION-IGNITION ENGINES--Table of Contents
Subpart B_Emission Standards and Certification Provisions
Sec. 89.112 Oxides of nitrogen, carbon monoxide, hydrocarbon, and
particulate matter exhaust emission standards.
(a) Exhaust emission from nonroad engines to which this subpart is
applicable shall not exceed the applicable exhaust emission standards
contained in Table 1, as follows:
[[Page 54]]
[GRAPHIC] [TIFF OMITTED] TR23OC98.001
(b) Exhaust emissions of oxides of nitrogen, carbon monoxide,
hydrocarbon, and nonmethane hydrocarbon are measured using the
procedures set forth in subpart E of this part.
[[Page 55]]
(c) Exhaust emission of particulate matter is measured using the
California Regulations for New 1996 and Later Heavy-Duty Off-Road Diesel
Cycle Engines. This procedure is incorporated by reference. See Sec.
89.6.
(d) In lieu of the NOX standards, NMHC + NOX
standards, and PM standards specified in paragraph (a) of this section,
manufacturers may elect to include engine families in the averaging,
banking, and trading program, the provisions of which are specified in
subpart C of this part. The manufacturer must set a family emission
limit (FEL) not to exceed the levels contained in Table 2. The FEL
established by the manufacturer serves as the standard for that engine
family. Table 2 follows:

(e) Naturally aspirated nonroad engines to which this subpart is
applicable shall not discharge crankcase emissions into the ambient
atmosphere, unless such crankcase emissions are permanently routed into
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:
Table 3--Voluntary Emission Standards (g/kW-hr)
------------------------------------------------------------------------
Rated Brake Power (kW) NMHC+NOX PM
------------------------------------------------------------------------
kW<8.............................................. 4.6 0.48
8<=kW<19.......................................... 4.5 0.48
19<=kW<37......................................... 4.5 0.36
37<=kW<75......................................... 4.7 0.24
75<=kW<130........................................ 4.0 0.18
130<=kW<=560...................................... 4.0 0.12
kW560.................................. 3.8 0.12
------------------------------------------------------------------------
(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).
