(d) Compliance Extensions. A municipality or utility may be granted an extension to
a compliance deadline specified in subsection (c) for one of the following
reasons:
(1) Compliance Extension Based on Early Implementation. A municipality or
utility may be granted an extension based on compliance with one or more
of the following early implementation schedules, provided the Executive
Officer has received a letter by the applicable early compliance deadline
stating the municipality's or utility's intent to comply with one of the
following conditions and the municipality or utility meets the requirements
set forth in paragraphs (A), (B), (C) or (D).
(A) If a municipality or utility has implemented best available control
technology on fifty percent or more of its Group 1 vehicles in its total
fleet by December 31, 2007, then the municipality or utility may
delay the intermediate and final compliance deadlines for the
remaining Group 1 vehicles to July 1, 2012.
(B) If a municipality or utility has implemented best available control
technology on fifty percent or more of its Group 2 vehicles in its total
fleet by December 31, 2007, then the municipality or utility may
delay the intermediate and final compliance deadlines for the
remaining Group 2 vehicles to July 1, 2012.
(C) If a municipality or utility has implemented BACT on 100 percent of
its Group 1 and Group 2 engines by December 31, 2008, then the
municipality or utility may follow the alternate implementation
schedule for its Group 3 engines of 20 percent BACT by
December 31, 2009, 60 percent BACT by December 31, 2011 and
100 percent BACT by December 31, 2012.
(D) If a municipality or utility employs significant quantities of advanced
technology vehicles (for example, hybrid electric vehicles) to meet
BACT requirements, then the municipality or utility may apply to the
Executive Officer for approval of a longer implementation schedule
for its Group 2 and Group 3 vehicles, or approval of credits to be
used towards BACT compliance. The longer implementation
schedule must be proportionate to the additional emissions benefits
from the use of the advanced technology vehicles, and BACT
credits cannot exceed the additional emissions benefits. The
advanced technology vehicles must meet or exceed
model -year 2007 and later emissions standards and significantly
reduce greenhouse gas emissions and petroleum use.
