In-Use Off-Road Diesel Vehicle Regulation

This page last reviewed March 17, 2014

Email Messages Sent to DOORS Fleets

ARB Off-Road Implementation staff periodically sends email messages to fleets who have reported in the Diesel Off-Road Online Reporting System (DOORS), the reporting system for the Off-Road Regulation.  The emails inform or remind fleets about upcoming reporting deadlines, training opportunities, and more. This page is an archive of all such messages sent out to DOORS fleets since January 2012.

Emails are often sent to a subset of DOORS fleets; for example, fleets in a certain fleet size category.  The "Sent to" column below indicates the subset of fleets to whom each message was sent. Fleets that do not have an email address associated with their DOORS account are mailed a hardcopy version (letter) of the email listed.

An archive of notices sent to the "ordiesel" List Serve is available here.
