49-573. Emissions controls; federal
vehicles


A. The operator of a United States government owned vehicle fleet based primarily
in this state shall develop and implement a vehicle fleet plan for the purpose of
encouraging and progressively increasing the use of alternative fuels and clean burning
fuels in United States government owned vehicles. The plan shall include a timetable for
increasing the use of alternative fuels and clean burning fuels in fleet vehicles either
through purchase or conversion.


B. The timetable shall reflect the following schedule and percentage of vehicles
that operate on alternative fuels and clean burning fuels:


1. At least ten per cent of the total fleet by December 31, 1994.


2. At least forty per cent of the total fleet by December 31, 1995.


3. For fleets operating primarily in counties with a population of more than one
million two hundred thousand persons according to the most recent United States decennial
census, at least ninety per cent of the total fleet by December 31, 1997 and each year
thereafter.


C. The requirements of subsections A and B of this section may be waived on receipt
of certification supported by evidence acceptable to the department of environmental
quality that the United States government fleet operator is unable to acquire or be
provided equipment or refueling facilities necessary to operate vehicles using
alternative fuels or clean burning fuels at a projected cost that is reasonably expected
to result in net costs of no greater than thirty per cent more than the net costs
associated with the continued use of conventional gasoline or diesel fuels measured over
the expected useful life of the equipment or facilities supplied. An entity that receives
a waiver pursuant to this section shall retrofit fleet heavy-duty diesel vehicles with a
gross vehicle weight of eight thousand five hundred pounds or more, that were
manufactured in or before model year 1993 and that are the subject of the waiver with a
technology that is effective at reducing particulate emissions at least twenty-five per
cent or more and that has been approved by the United States environmental protection
agency pursuant to the urban bus engine retrofit/rebuild program. The entity shall comply
with the implementation schedule pursuant to section 49-555.


D. If the requirements of subsections A and B of this section are met by the use of
clean burning fuel, vehicle equivalents under those requirements shall be calculated as
follows:


1. One vehicle equivalent for every four hundred fifty gallons of neat biodiesel or
two thousand two hundred fifty gallons of a diesel fuel substitute prescribed in section
1-215, paragraph 7, subdivision (b).


2. One vehicle equivalent for every five hundred thirty gallons of the fuel
prescribed in section 1-215, paragraph 7, subdivision (d).
