PART 1048_CONTROL OF EMISSIONS FROM NEW, LARGE NONROAD SPARK-IGNITION 

ENGINES--Table of Contents

 

          Subpart B_Emission Standards and Related Requirements

 

Sec.  1048.145  Are there interim provisions that apply only for a 

limited time?



    The provisions in this section apply instead of other provisions in 

this part. This section describes when these interim provisions expire.

    (a) Family banking. This paragraph (a) allows you to reduce the 

number of engines subject to the Tier 2 standards by certifying some of 

your engines earlier than otherwise required, as follows:

    (1) For early-compliant engines to generate offsets under this 

paragraph (a), you must meet the following general provisions:

    (i) You must begin actual production of early-compliant engines by 

September 1, 2006.

    (ii) Engines you produce after December 31, 2006 may not generate 

offsets.

    (iii) Offset-generating engines must be certified to the Tier 2 

standards and requirements under this part 1048.

    (iv) If you certify engines under the voluntary standards of Sec.  

1048.140, you may not use them in your calculation under this paragraph 

(a).

    (2) For every offset-generating engine certified to the Tier 2 

standards, you may reduce the number of engines with the same maximum 

engine power that are required to meet the Tier 2 standards in later 

model years by one engine. You may calculate power-weighted offsets 

based on actual U.S.-directed sales volumes. For example, if you produce 

a total of 1,000 engines in 2005 and 2006 with an average maximum power 

of 60 kW certified to the Tier 2 standards, you may delay certification 

to that tier of standards for up to 60,000 kW-engine-years in any of the 

following ways:

    (i) Delay certification of up to 600 engines with an average maximum 

power of 100 kW for one model year.

    (ii) Delay certification of up to 200 engines with an average 

maximum power of 100 kW for three consecutive model years.

    (iii) Delay certification of up to 400 engines with an average 

maximum power of 100 kW for one model year and up to 50 engines with an 

average maximum power of 200 kW for two model years.

    (3) Offset-using engines (that is, those not required to certify to 

the Tier 2 standards) must be certified to the Tier 1 standards and 

requirements of this part 1048. You may delay compliance for up to three 

model years.

    (4) By January 31 of each year in which you use the provisions of 

this paragraph (a), send us a report describing how many offset-

generating or offset-using engines you produced in the preceding model 

year.

    (b) Hydrocarbon standards. For 2004 through 2006 model years, engine 

manufacturers may use nonmethane hydrocarbon measurements to demonstrate 

compliance with applicable emission standards.

    (c) [Reserved]

    (d) Tier 1 deterioration factors. For Tier 1 engines, base the 

deterioration factor from Sec.  1048.240 on 3500 hours of operation. We 

may assign a deterioration factor for a Tier 1 engine family, but this 

would not affect your need to meet all emission standards that apply.

    (e) [Reserved]

    (f) Optional early field testing. You may optionally use the field-

testing procedures in subpart F of this part for any in-use testing 

required under subpart E of this part to show that you meet Tier 1 

standards. In this case, the same Tier 1 in-use emission standards apply 

to both steady-state testing in the laboratory and field testing.

    (g) Small-volume provisions. If you qualify for the hardship 

provisions in Sec.  1068.250 of this chapter, we may approve extensions 

of up to four years total.

    (h) 2004 certification. For the 2004 model year, you may choose to 

have the emission standards and other requirements that apply to these 

engines in California serve as the emission standards and other 

requirements applicable under this part, instead of those in subpart A 

of this part. To ask for a certificate under this paragraph (h), send us 

the application for certification that you prepare for the California 

Air Resources Board instead of the information we otherwise require in 

Sec.  1048.205.

    (i) Recreational vehicles. Engines or vehicles identified in the 

scope of 40 CFR part 1051 that are not yet regulated under that part are 

excluded from the requirements of this part. For example, snowmobiles 

produced in 2004 are not subject to the emission standards in this part. 

Once emission standards apply to these engines and vehicles, they are 

excluded from the requirements of this part under Sec.  1048.5(a)(1).
