Control of Air Pollution; Amendments to Emission Requirements 
Applicable to New Nonroad Compression-Ignition Engines at or Above 37 
Kilowatts: Provisions for Replacement Compression-Ignition Engines and 
the Use of On-Highway Compression-Ignition Engines in Nonroad Vehicles

AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice of proposed rule (NPRM).




SUMMARY: This NPRM proposes to amend the regulations applicable to 
compression-ignition nonroad engines at or above 37 kilowatts (kW) to 
address two disruptive situations that have arisen regarding the 
implementation of regulations applicable to these nonroad engines. No 
air quality impact is expected from these amendments.
    This NPRM proposes to allow nonroad vehicle manufacturers to use 
certified on-highway engines in nonroad vehicles that are constructed 
from on-highway vehicles or that must use public roads between job 
sites. These amendments also propose to allow engine manufacturers to 
provide uncertified replacement engines to repower pre-regulation 
nonroad equipment when that equipment experiences major engine failure 
and a suitable certified engine that will fit in the equipment is not 
available.

    Because the rule revision is not expected to receive any adverse 
comments, the revision is also being issued as a direct final rule in a 
separate part of this Federal Register

DATES: Public comments on the amendments proposed herein will be 
accepted until December 12, 1996 or 30 days after the date of a public 
hearing if one is held.

    The Agency will hold a public hearing regarding these proposed 
amendments on December 6, 1996 if it receives a request to testify at a 
hearing by November 22, 1996. The Agency will cancel this hearing if no 
one requests to testify. Members of the public should call the contact 
person indicated below to notify EPA of their interest in testifying at 
the hearing. Interested parties may call the contact person after 
November 22, 1996 to determine whether and where the hearing will be 
held.

ADDRESSES: Interested parties may submit written comments (in 
duplicate) for EPA consideration by addressing them as follows: EPA Air 
Docket (LE-131), Attention: Docket Number A-96-37, room M-1500, 401 M 
Street, S.W., Washington, D.C. 20460. Please contact the individual
