                   TITLE 40--PROTECTION OF ENVIRONMENT
 
         CHAPTER I--ENVIRONMENTAL PROTECTION AGENCY (CONTINUED)
 
PART 86--CONTROL OF EMISSIONS FROM NEW AND IN-USE HIGHWAY VEHICLES AND ENGINES--Table of Contents
 
  Subpart A--General Provisions for Emission Regulations for 1977 and 
 
Sec. 86.005-1  General applicability.

    Section 86.005-1 includes text that specifies requirements that 
differ from Sec. 86.001-1. Where a paragraph in Sec. 86.001-1 is 
identical and applicable to Sec. 86.005-1, this may be indicated by 
specifying the corresponding paragraph and the statement ``[Reserved]. 
For guidance see Sec. 86.001-1.''.
    (a) Applicability. The provisions of this subpart generally apply to 
2005 and later model year new Otto-cycle heavy-duty engines used in 
incomplete vehicles and vehicles above 14,000 pounds GVWR and 2005 and 
later model year new diesel-cycle heavy-duty engines. In cases where a 
provision applies only to a certain vehicle group based on its model 
year, vehicle class, motor fuel, engine type, or other distinguishing 
characteristics, the limited applicability is cited in the appropriate 
section or paragraph. The provisions of this subpart continue to 
generally apply to 2000 and earlier model year new Otto-cycle and 
diesel-cycle light-duty vehicles, 2000 and earlier model year new Otto-
cycle and diesel-cycle light-duty trucks, and 2004 and earlier model 
year new Otto-cycle complete heavy-duty vehicles at or below 14,000 
pounds GVWR. Provisions generally applicable to 2001 and later model 
year new Otto-cycle and diesel-cycle light-duty vehicles, 2001 and later 
model year new Otto-cycle and diesel-cycle light-duty trucks, and 2005 
and later model year Otto-cycle complete heavy-duty vehicles at or below 
14,000 pounds GVWR are located in subpart S of this part.
    (b) Optional applicability. (1) A manufacturer may request to 
certify any 2003 or 2004 model year heavy-duty vehicle of 14,000 pounds 
Gross Vehicle Weight Rating or less in accordance with the light-duty 
truck provisions located in subpart S of this part. Heavy-duty engine or 
vehicle provisions of this subpart A do not apply to such a vehicle. 
This option is not available in the 2003 model year for manufacturers 
choosing Otto-cycle HDE option 1 in paragraph (c)(1) of this section, or 
in the 2004 model year for manufacturers choosing Otto-cycle HDE option 
2 in paragraph (c)(2) of this section.
    (2) For 2005 and later model years, a manufacturer may request to 
certify any incomplete Otto-cycle heavy-duty vehicle of 14,000 pounds 
Gross Vehicle Weight Rating or less in accordance with the provisions 
for Otto-cycle complete heavy-duty vehicles located in subpart S of this 
part. Heavy-duty engine or heavy-duty vehicle provisions of this subpart 
A do not apply to such a vehicle. This option is available starting with 
the 2003 model year to manufacturers choosing Otto-cycle HDE option 1 in 
paragraph (c)(1) of this section. This option is available starting with 
the 2004 model year to manufacturers choosing Otto-cycle HDE option 2 in 
paragraph (c)(1) of this section.
    (c) Otto-cycle heavy-duty engines and vehicles. The manufacturer 
must select one of the three options for Otto-cycle heavy-duty engines 
and vehicles in paragraphs (c)(1) through (c)(3) of this section. The 
emission standards and other requirements that apply under a given 
option shall apply to all Otto-cycle heavy-duty engines and vehicles 
certified by the manufacturer (e.g., a manufacturer may not select one 
option for certain engine families and the other option for other engine 
families). The requirements under each option shall remain effective, 
once selected, for subsequent model years, until superceded or otherwise 
revised by the Administrator (e.g., a manufacturer may not select one 
option prior to the 2004 model year and change to another option in the 
2006 model year). The complete requirements under each option are 
contained in subparts A and S of this part.
    (1) Otto-cycle HDE Option 1. The following requirements apply to 
Otto-cycle heavy-duty engines and vehicles

certified by manufacturers selecting this option:
    (i) Emission standards for 2003 and later model year Otto-cycle 
heavy-duty engines, according to the provisions of Sec. 86.005-10(f)(1).

complete heavy-duty vehicles, according to the provisions of

cycle complete heavy-duty vehicles, manufacturers may optionally comply 
with the standards in either 86.005-10 or 86.1816-05.
    (iii) Averaging, banking, and trading provisions that allow transfer 
of credits between a manufacturer's complete vehicle averaging set and 
their heavy-duty Otto-cycle engine averaging set, according to the 
provisions of Sec. 86.1817-05(o).
    (iv) On-board diagnostics requirements effective starting with the 
2004 model year for Otto-cycle engines and complete vehicles, according 
to the provisions of Secs. 86.005-17 and 86.1806-05.
    (v) Refueling emissions requirements effective starting with the 
2004 model year for Otto-cycle complete vehicles, according to the
