                   TITLE 40--PROTECTION OF ENVIRONMENT
 
         CHAPTER I--ENVIRONMENTAL PROTECTION AGENCY (CONTINUED)
 
PART 90--CONTROL OF EMISSIONS FROM NONROAD SPARK-IGNITION ENGINES AT OR 
BELOW 19 KILOWATTS--Table of Contents
 
       Subpart B--Emission Standards and Certification Provisions
 
Sec. 90.114  Requirement of certification--engine information label.

    (a) The engine manufacturer must affix at the time of manufacture a 
permanent and legible label identifying each nonroad engine. The label 
must meet the following requirements:
    (1) Be attached in such a manner that it cannot be removed without 
destroying or defacing the label;
    (2) Be durable and readable for the entire engine life;
    (3) Be secured to an engine part necessary for normal engine 
operation and not normally requiring replacement during engine life;
    (4) Be written in English; and
    (5) Be located so as to be readily visible to the average person 
after the engine is installed in the vehicle.
    (b) If the nonroad vehicle obscures the label on the engine, the 
nonroad vehicle manufacturer must attach a supplemental label so that 
this label is readily visible to the average person. The supplemental 
label must:
    (1) Be attached in such a manner that it cannot be removed without 
destroying or defacing the label;
    (2) Be secured to a vehicle part necessary for normal operation and 
not normally requiring replacement during the vehicle life; and
    (3) Be identical in content to the label which was obscured.
    (c) The label must contain the following information:
    (1) The heading ``Important Engine Information;''
    (2) The full corporate name and trademark of the engine 
manufacturer;
    (3) The statement, ``This (specify vehicle or engine, as applicable) 
is certified to operate on (specify operating fuel(s));''
    (4) Identification of the Exhaust Emission Control System 
(Abbreviations may be used and must conform to the nomenclature and 
abbreviations provided in the Society of Automotive Engineers procedure 
J1930, ``Electrical/Electronic Systems Diagnostic Terms, Definitions, 
Abbreviations and Acronyms,'' September 1991. This procedure has been 
incorporated by reference. See Sec. 90.7.);
    (5) All engine lubricant requirements;
    (6) Date of engine manufacture [day (optional), month and year];
    (7) The statement ``This engine conforms to [model year] U.S. EPA 
regulations for small nonroad engines.'';
    (8) EPA standardized engine family designation;
    (9) Engine displacement [in cubic centimeters];
    (10) Other information concerning proper maintenance and use or 
indicating compliance or noncompliance with other standards may be 
indicated on the label;
    (11) For Phase 2 engines, the useful life category as determined by 
the manufacturer pursuant to Sec. 90.105. Such useful life category 
shall be shown by one of the following statements to be

[[Page 185]]

appended to the statement required under paragraph (c)(7) of this 
section:
    (i) ``EMISSIONS COMPLIANCE PERIOD: [useful life] HOURS''; or
    (ii) ``EMISSIONS COMPLIANCE PERIOD: CATEGORY [fill in C, B or A as 
indicated and appropriate from the tables in Sec. 90.105], REFER TO 
OWNER'S MANUAL FOR FURTHER INFORMATION'';
    (d) If there is insufficient space on the engine (or on the vehicle 
where a supplemental label is required under paragraph (b) of this 
section) to accommodate a label including all the information required 
in paragraph (c) of this section, the manufacturer may delete or alter 
the label as indicated in this paragraph. The information deleted from 
the label must appear in the owner's manual.
    (1) Exclude the information required in paragraphs (c)(3), (4), and 
(5) of this section. The fuel or lubricant may be specified elsewhere on 
the engine.
    (2) Exclude the information required by paragraph (c)(6) of this 
section, if the date the engine was manufactured is stamped on the 
engine.
    (e) The Administrator may, upon request, waive or modify the label 
content requirements of paragraphs (c) and (d) of this section, provided 
that the intent of such requirements is met.
    (f) Manufacturers electing to use the labeling language of paragraph 
(c)(11)(ii) of this section must provide in the documents intended to be 
conveyed to the ultimate purchaser, the statement:
    (1) For nonhandheld engines: The Emissions Compliance Period 
referred to on the Emissions Compliance label indicates the number of 
operating hours for which the engine has been shown to meet Federal 
emission requirements. For engines less than 66 cc, Category C=50 hours, 
B=125 hours, and A=300 hours. For engines equal to or greater than 66 cc 
but less than 225 cc displacement, Category C=125 hours, B=250 hours, 
and A=500 hours. For engines of 225 cc or more, Category C=250 hours, 
B=500 hours, and A=1000 hours.
    (2) For handheld engines: The Emissions Compliance Period referred 
to on the Emissions Compliance label indicates the number of operating 
hours for which the engine has been shown to meet Federal emission 
requirements. Category C=50 hours, B=125 hours, and A=300 hours.
    (3) The manufacturer must provide, in the same document as the 
statement in paragraph (f)(1) or (f)(2) of this section, a statement of 
the engine's displacement or an explanation of how to readily determine 
the engine's displacement. The Administrator may approve alternate 
language to the statement in paragraph (f)(1) or (f)(2) of this section, 
provided that the alternate language provides the ultimate purchaser 
with a clear description of the number of hours represented by each of 
the three letter categories for the subject engine's displacement.
