PM BACT Phase is option to the BACT By Model Year compliance path. Under this option rather than having to comply with PM BACT based on the vehicle engine model year, fleet owners are allowed to bring a percentage of the fleet into compliance with PM BACT each year. The percentages and compliance deadlines are given below.
|Percentage of Fleet that Must
Have a DPF
|Jan 1, 2012||30%|
|Jan 1, 2013||60%|
|Jan 1, 2014||90%|
|Jan 1, 2015||90%|
|Jan 1, 2016||100%|
So for example, if you ten vehicles subject to PM BACT by Jan 1, 2013 six of your vehicle would have to comply. The advantage of PM BACT Phase In is that gives fleet owners the ability to decide which vehicles to retrofit first.
One the vehicle has DPF then it must meet the 2010 engine compliance schedule given in the BACT by Model Year discussion.
As indicated by the compliance chart, a variety of credits are available under this compliance path.
To use this option the credits available under this compliance path you need to report your entire fleet of heavier trucks.
