‘‘(B) Establishing, managing, and sup-
porting an enforcement program that ensures 
that the facility is being operated in accordance 
with the requirements of this section. 
‘‘(C) Limiting or discontinuing the use of 
the facility by such vehicles if the presence of 
such vehicles has degraded the operation of the 
facility. 
‘‘(2) DEGRADED FACILITY.—
‘‘(A) IN GENERAL.—For purposes of para-
graph (1), the operation of a HOV facility shall 
be considered to be degraded if vehicles oper-
ating on the facility are failing to maintain a

the time over a consecutive 6-month period dur-
ing morning or evening weekday peak hour pe-
riods (or both). 
‘‘(B) 
MINIMUM
AVERAGE
OPERATING 
SPEED
DEFINED.—In subparagraph (A), the 
term 
‘minimum 
average 
operating 
speed’ 
means—
‘‘(i) 45 miles per hour, in the case of 
a HOV facility with a speed limit of 50 
miles per hour or greater; and 
‘‘(ii) not more than 10 miles per hour 
below the speed limit, in the case of a 
HOV facility with a speed limit of less 
than 50 miles per hour. 
‘‘(e) CERTIFICATION OF LOW EMISSION AND EN-
ERGY-EFFICIENT VEHICLES AND ADVANCED LEAN BURN 
TECHNOLOGY VEHICLES.—Not later than 6 months after 
the date of enactment of this section, the Administrator 
of the Environmental Protection Agency shall issue— 
‘‘(1) a final rule establishing requirements for 
certification of a vehicle for purposes of this section 
as— 
‘‘(A) a low emission and energy-efficient 
vehicle; or 
‘‘(B) an advanced lean burn technology ve-
hicle; and 
‘‘(2) requirements for the labeling of such vehi-
cles. 
‘‘(f) FUEL EFFICIENCY GUIDANCE FOR HYBRID VE-
HICLES.—Not later than 6 months after the date of enact-
ment of this section, the Administrator of the Environ-
mental Protection Agency shall issue guidance on methods
for determining whether a vehicle meets the fuel efficiency 
standards required to qualify as a hybrid vehicle under 
subsection (g). 
‘‘(g) DEFINITIONS.—In this section, the following 
definitions apply: 
‘‘(1) ADVANCED LEAN BURN TECHNOLOGY VE-
HICLE.—The term ‘advanced lean burn technology 
vehicle’ means a vehicle with an internal combustion 
engine that is designed to operate primarily using
