98(4) A municipality or utility not specifically listed in Table 2 may apply to the
Executive Officer for consideration as a fleet located in a designated
"low- population county." The Executive Officer shall issue that
designation provided that all of the following criteria are met:
(A) The total fleet is located in a "nonurbanized area," a "rural and small
urban area," or any area outside of an urbanized area, as
designated by the U.S. Bureau of the Census. An urbanized area
consists of a core area and the surrounding densely populated area
with a total population of 50,000 or more, with boundaries fixed by
the Bureau of the Census or extended by state and local officials; or
(B) The fleet is located in a county that, as of July 1, 2005, has a
population of less than 325,000 and meets the definition of a low -
population county when the population of one or more cities that
have their own municipal vehicle fleet are subtracted from the
county population, and the fleet does not operate within those cities'
boundaries; and
(C) The fleet revenue is not based on special district assessments or
fees.
(5) Calculating Number of Total Fleet Vehicles Required for Implementation.
(A) As of January 1 of each year where a compliance deadline is
applicable, a municipality or utility shall calculate, for each engine
model -year group, the number of vehicles in its total fleet for which
compliance will be required. This fleet size by engine model -year
group ( #MUVby g,o„ p)2 must be calculated using the following
equation:
#MUVbyg,p„p = # VehiclesbY9ro„p + TotRetirebY9,o„p
Where:
#Vehiclesby group = the number of vehicles in an engine model -year group
subject to the rule, and
TotRetireby group =the number of vehicles removed from the model -year
group by retirement in prior years, beginning with
January 1 of the initial applicable compliance deadline
year for each group.
If a vehicle has left the total fleet for reasons other than retirement, it
must not be included in the calculation of #MUVby group.
2 "by group" means all vehicles in an engine model -year group as described in Table 1 under (c)(1).
