Portable Engine ATCMPOTENTIAL CHANGES

Draft ATCM Changes

Emission Reduction StrategiesTier phase out for all fleets:

Fleet defined as all engines operated in California owned by a single entity– Small fleets are 750 total bhp or less, large fleets are

>750 total bhp – Each military installation will be it’s own fleet– Pre-2007 on-highway engines will be treated as Tier 3 for

phase out

Draft ATCM ChangesLarge fleets have fleet average option:

Criteria for large fleets to use fleet average—All engines in fleet subject to ATCM must be registered in

PERP—Must submit a request by 2019 to use option—If fleet has unpermitted engines after 2019, out of fleet

averageRetrofitted engines exempt from phase-out requirements

—Must have verified Level 3 diesel particulate filter

—Still included in Fleet Average option for large fleets

Draft ATCM Changes Low-use and emergency-use engines exempt from

fleet requirements— Low-use engines increased to 200 hr/yr— Must designate Tier 1 & 2 engines 6 months prior

to phase-out — Can’t convert Tier 1 & 2 to regular use unless

exceed limitation— Separated by size category (<175, 175 - 750, >750)

— Two extra years for phase-out OR— Double count T4 in fleet average for first two

dates

Benefit for fleets in compliance with 2017 fleet standards

Benefit for removing Tier 1 and Tier 2 engines early— Must be removed from service in California— Remove all Tier 1 by 1/1/2019 and Tier 2 (≤750 bhp) by

1/1/2020 — Extra 2 years for Tier 3 (including flex) on phase-out

schedule only
