Heavier trucks and buses with a GVWR greater than 26,000 pounds must comply with the following schedule by engine model year unless owners can report to show compliance with the more flexible options listed above in sections 1-7.
Engine Model Year Requirements for Heavier Trucks from January 1
Pre-1994 No requirements until 2015, then 2010 engine
1994-1995 No requirements until 2016, then 2010 engine
1996-1999 PM filter from 2012 to 2020, then 2010 engine
2000-2004 PM filter from 2013 to 2021, then 2010 engine

2007-2009* No requirements until 2023, then 2010 engine
2010 Meets final requirements
*Must have PM filter by January 1, 2014, if not originally equipped
Starting January 1, 2012, heavier trucks were required to meet the engine model year schedule shown above. Fleets that comply with the schedule must install the best available PM filter on 1996 model year and newer engines and replace the vehicle 8 years later. Trucks with 1995 model year and older engines must be replaced starting 2015. Replacements with a 2010 model year or newer engines meet the final requirements, but owners can also replace with used trucks that have a future compliance date on the schedule. For example, a replacement with a 2007 model year engine complies until 2023. By 2023, all trucks and buses must have 2010 model year engines with few exceptions. No reporting is required if complying with this schedule.
Compliance requirements for lighter trucks and buses (14,000-26,000 GVWR)Lighter trucks and buses with a GVWR of 14,001 to 26,000 pounds do not have compliance requirements until 2015. Below is the Engine Model Year Schedule for Lighter Trucks that lists the compliance dates that apply by engine model year for lighter trucks. Starting January 1, 2015, lighter trucks with engines that are 20 years or older will need to be replaced with newer trucks. No reporting is required.
Engine Model Year Schedule for Lighter Trucks
Engine Year 2010 Replacement Date
1995 and older January 1, 2015
1996 January 1, 2016
1997 January 1, 2017
1998 January 1, 2018

2003 and older January 1, 2020
2004-2006 January 1, 2021
2007-2009 January 1, 2023
Replacements with a 2010 model year or newer engines meet the final requirements, but owners can also replace with used trucks that have a future compliance date on the schedule. PM filter retrofits cannot be used to comply with this option; however, owners that installed a PM filter retrofit on a lighter truck by January 1, 2014 and reported by January 31, 2015 can continue to operate the vehicle until January 1, 2023.
