1) Not to be combined with other rear aerodynamic

devices

2) The device is granted preliminary approval for use

only when it is used in combination with other preliminary-approved devices to achieve a composite delta CdA value equal to or greater than 0.40 square meters.

a) Preliminary-approved devices with delta CdA values less than 0.40 square meters, that are used on a pre-2020 model-year (i.e., noncertified) long dry-van trailer or long refrigerated-van trailer, as applicable,

that travel on a highway in California, are required to be combined with other devices to generate a delta CdA value equal to or greater than 0.40 square meters in order to be in compliance with the requirements of the California

Tractor-Trailer Greenhouse Gas regulations, as specified in title 17 CCR section 95303(b). This requirement does not apply for 2020 and later model-year trailers that are certified under the Phase 2 Greenhouse Gas regulations.

b) The measured delta CdA value of the devices with delta CdA values less than 0.40 square meters, can be used individually or with the measured delta CdA values of other preliminary- approved devices

as part of a composite delta CdA value calculation for all aerodynamic devices used with a trailer configuration to determine the corresponding trailer Bin-designated delta CdA value.

c) All of the listed devices granted preliminary approval are valid only for use on the heavy-duty trailer types through the 2020 model year.

d) NA = not applicable. This applies to devices evaluated by CARB directly and not a U.S. EPA preapproved package.

e) TGRT=Gap reducing trailer fairing; TATS=Trailer aerodynamic side skirt; TARF=Trailer aerodynamic rear fairing; TAUD=Trailer aerodynamic underbody device

f) WT=wind tunnel; CFD=computational fluid dynamics; CD=coastdown
