    (c) Send the Designated Officer a written request if you want us to 
determine whether this part covers or excludes certain engines. 
Excluding engines from this part's requirements does not affect other 
requirements that may apply to them.
    Note: See 40 CFR part 87 for engines used in aircraft.)
    (d) As defined in Sec. 1048.801, stationary engines are not 
required to comply with this part (because they are not nonroad

In addition, the prohibitions in 40 CFR 1068.101 restrict the use of 
stationary engines for non-stationary purposes.
