[FRL-5871-2]

Control of Air Pollution; Amendments to Emission Requirements
Applicable to New Nonroad Spark Ignition Engines At or Below 19
Kilowatts and New Marine Spark Ignition Engines: Provisions for
Replacement Engines and the Use of Two Stroke Engines on Certain
Nonhandheld Equipment

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

-----------------------------------------------------------------------

SUMMARY: This NPRM proposes to amend the regulations applicable to
spark-ignition nonroad engines at or below 19 kilowatts (kW) and spark
ignition marine engines to address issues that have arisen with the
implementation of regulations applicable to these nonroad engines. No
significant air quality impact is expected from these amendments.
    This NPRM proposes to allow engine manufacturers to provide
uncertified engines to replace older engines when major engine failures
occur and no suitable certified engine is available that will fit in
the nonroad equipment or marine outboard or personal watercraft. The
proposed amendments would also allow manufacturers of nonhandheld
equipment who have historically used two stroke engines to avail
themselves of an option currently available only to lawnmower
manufacturers that have historically used two stroke engines. The
current regulation permits the lawnmower manufacturers to have
additional time to convert to engines that will meet the more stringent
nonhandheld standards. The proposed amendment would extend the option
to other types of nonhandheld equipment, subject to appropriate
constraints.
    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 September 8, 1997 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 August 27, 1997 if it receives a request to testify at a
hearing by August 18, 1997. 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
August 18, 1997 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-97-25, room M-1500, 401 M
Street, S.W., Washington, D.C. 20460. Please contact the individual
listed below before submitting comments.
    Materials relevant to this rulemaking are contained in the docket
listed above and may be reviewed at that location from 8:00 am until
5:30 pm Monday through Friday. As provided in 40 CFR Part 2, a
reasonable fee may be charged by EPA for photocopying.

FOR FURTHER INFORMATION CONTACT: John Guy, Office of Mobile Sources,
Engine Programs and Compliance Division (6403J), 401 M Street S.W.,
Washington, D.C. 20460, 202-233-9276.

SUPPLEMENTARY INFORMATION:

Regulated Entities

    Entities potentially regulated by this action are those which
manufacture and use spark-ignition nonroad engines of 19 kW or less and
those entities which manufacture and use spark-ignition marine outboard
or personal watercraft (including jetboat) engines. Regulated
categories and entities include:

------------------------------------------------------------------------
             Category                  Examples of regulated entities
------------------------------------------------------------------------
Industry..........................  Manufacturers and users of spark-
                                     ignition engines of 19 kW or less.
                                    Manufacturers and users of marine
                                     spark-ignition outboard or personal
                                     watercraft engines
------------------------------------------------------------------------

    This table is not intended to be exhaustive, but rather provides a
guide for readers regarding entities likely to be regulated by this
action. This table lists the types of entities that EPA is now aware
could potentially be regulated by this action. Other types of entities
not listed in the table could also be regulated. To determine whether
your product is regulated by this action, you should carefully examine
the applicability criteria in Secs. 90.1 and 91.1 of title 40 of the
Code of Federal Regulations. If you have questions regarding the
applicability of this action to a particular product, consult the
person listed in the preceding FOR FURTHER INFORMATION CONTACT section.
    If no adverse comments are timely received, no further activity is
contemplated in relation to this proposed rule and the direct final
rule in a separate part of this Federal Register will automatically go
into effect on the date specified in that rule. If adverse comments are
timely received on the direct final rule, the rule will be withdrawn in
whole or in part and all public comment received on it will be
addressed in a subsequent final rule based on this proposed rule.
Because the Agency will not institute a second comment period on this
proposed rule, any parties interested in commenting should do so during
this comment period. For further supplemental information, the detailed
rationale, and the rule revisions, see the information provided in the
direct final rule in a separate part of this Federal Register.
