                   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 C--Certification Averaging, Banking, and Trading Provisions
 
Sec. 90.213  Averaging under the optional program.

    (a) Negative credits from engine families with FELs above the 
applicable emission standard must be offset by positive credits from 
engine families having FELs below the applicable emission standard, as 
allowed under the provisions of this subpart. Averaging of credits in 
this manner is used to determine compliance under Sec. 90.216(b).
    (b) Cross-class averaging of credits is allowed across all classes 
of nonroad spark-ignition handheld engines at or below 19 kW 
participating in the optional transition year program.
    (c) Credits used in averaging for a given model year may be obtained 
from credits generated in the same model year by another engine family, 
credits banked in previous model years, or credits of the same or 
previous model year obtained through trading. The restrictions of this 
paragraph (c) notwithstanding, credits from a given model year may be 
used to address credit needs of previous model year engines as allowed 
under Sec. 90.216(c).
    (d) The use of credits generated under the early banking provisions 
of Sec. 90.214(b) is subject to regulations under this subpart.
