40 CFR Parts 90 and 91

[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

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 §§ 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.
