onrdiesel -- Recognition of Good Faith Compliance Efforts and Expected Truck and Bus Regulation Changes

Posted: 13 Nov 2013 17:44:34
The Air Resources Board (ARB or Board) has issued Regulatory
Advisory, Mail-Out MSC# 13-28, describing steps ARB is taking to
assist vehicle owners with the transition to the upcoming January
1, 2014, particulate matter (PM) filter compliance deadline under
the Truck and Bus regulation (regulation).   The overall goal of
these actions is to provide additional time for owners to
complete specific good faith compliance efforts and to provide
additional flexibility for many lower use vehicles and vehicles
that operate solely in certain areas of the State.  The advisory
is available at:
http://www.arb.ca.gov/msprog/onrdiesel/regulation.htm

To qualify and use the compliance options described in the
Advisory, truck owners must report specific information to ARB
through the Truck Regulations Upload and Compliance Reporting
System (TRUCRS) by January 31, 2014.

ARB recognizes that many fleets are taking actions to comply with
the January 1, 2014, deadline but may not be able to complete
them on time.  For such fleets, ARB is providing guidance to
truck owners that are compliant for 2013 and have made good faith
efforts to comply with the January 1, 2014, deadline by giving
assurance that they will not be subject to enforcement action for
non-compliance prior to July 1, 2014.

In addition, at its October 24, 2013, meeting, the Board directed
ARB staff to examine several potential changes to the regulation
that could provide owners additional compliance flexibility.  In
developing these changes, staff will evaluate them to ensure that
emission levels remain similar to what would be expected under
the current regulation, and do not jeopardize a region’s ability
to meet health-based federal air quality standards.  Potential
changes include increasing low-use vehicle thresholds, allowing
owners to newly opt-in to a number of existing flexibility
provisions, providing adjustments to the “NOx exempt” vehicle
provisions, and granting additional time for fleets in certain
areas to meet PM filter requirements.  Because it is not expected
that the Board will formally consider these changes until April
2014, the advisory allows owners to report and take advantage of
these anticipated regulatory changes where applicable.
