ARB and the Division of Occupational Safety and
Health (Cal/OSHA) have agreed on an
interim retrofit visibility policy to address retrofit visibility concerns
for off-road diesel vehicles. This policy will be used to address visibility concerns regarding retrofits required by
the March 1, 2010, in-use off-road diesel vehicle regulation compliance date for large fleets.
For the 2010 compliance date, the exhaust retrofit will not be allowed to increase visibility masking
(blocking the line of sight of the operator) in any direction.
Where a retrofit would block visibility, the installer or fleet must assess another location on the vehicle. When there are no
possible locations on a vehicle for a retrofit to be installed without creating visibility masking, that vehicle will
not be required to be retrofit for the March 1, 2010, off-road regulation requirements (see the exemption process below).
The interim policy only applies to the March 1, 2010, compliance date; a vehicle exempted from the retrofit requirements
in 2010 due to visibility will not necessarily continue to receive exemptions in future years.

Example Installations with No Visibility Impairment
|
|
The vehicles listed below were retrofit in a manner that meets the interim retrofit visibility policy
(i.e., without blocking the line of sight of the operator
in any direction). These are not the only methods in which the vehicles could be safely retrofit, they are just
examples of ways to retrofit such vehicles without impairing visibility.
Fleets applying for a retrofit exemption for these vehicle models should consider these locations carefully when
determining whether a vehicle can be retrofit. As soon as possible, ARB will add information on the exact dimensions of the
retrofits below to further assist fleets.

Vehicles Exempt from 2010 Retrofit Requirements
|
|
When ARB grants a request for a retrofit exemption for a vehicle make and model based on evidence that the vehicle could
not have a retrofit safely installed in any location without violating the interim retrofit visibility policy,
that vehicle make and model will be posted here.
Additionally, ARB has posted information on the vehicles that are in the exemption process on the
exemptions page.

Interim Retrofit Visibility Guide and Exemption
|
|
| |
 |
The
Retrofit Visibility Guide includes information on installing retrofits without
violating the Interim Visibility Policy, as well as how to request an exemption
from retrofit requirements if the vehicle cannot be retrofit without creating visibility impairment.
Fleet owners interested in applying for an exemption should first read the guide to determine whether their vehicles
could be retrofit without violating the Interim Visibility Policy, and then (if necessary) follow the instructions on
submitting an exemption request. The Occupational Safety and Health Standards Board has
agreed that retrofits installed
without creating visibility impairment per the guide will be in compliance with future proposed amendments to Cal/OSHA
standards concerning retrofit visibility.
