State Issues | Air Quality Issues


Presentation of ARA/ARACA CARB Training Manual Photo

The California Air Resources Board (CARB) is the state agency that is tasked with writing, implementing, and enforcing the majority of the air quality regulations passed by the California legislature. When the Federal Clean Air Act was passed in 1970, the Congress recognized that California had the nation’s most challenging air quality issues. As a result, California was granted extraordinary authority to regulate sources of pollution within their state. However, California’s regulatory really goes beyond the borders of their state because the Clean Air Act allows other states to adopt California regulations once the federal Environmental Protection Agency has reviewed and approved them. That means that the regulations California has placed on in-use diesel equipment could come to your state sometime in the future. 
This page of the ARA website contains an archive of California regulations that potentially affect rental businesses as well as ARA’s comments on several regulatory actions that have been taken in recent years.

CARB Update October 2010

In October 2010, the California Air Resources Board released proposals to augment the regulations on off-road diesel equipment and on-road diesel trucks. ARA worked very hard behind the scenes with the CARB staff to provide them with critical information about how the emissions from these two sets of vehicles are produced. Central to our analysis is the premise that you need to burn fuel to create emissions. Through the work of Dr. Mike Graboski, ARA was able to show that the amount of diesel fuel used in off-road equipment could not possibly generate the level of emissions contained in CARB’s emissions inventory. While others also played a significant role in pushing CARB to make changes in their rules, ARA’s contribution to this result is second to none. We will continue to work with CARB staff as the rules evolve.

The following story provides the basic details of the regulatory changes as we know them today. Your membership in ARA and ARA of California, and your support of ARA’s efforts to represent equipment rental businesses in California is in the end what really made this effort possible.

There are a number of issues, updates, and points of information that you need to know about California Air Resources Board regulations for off-road diesel equipment, on-road trucks and portable equipment. The following is an update on each regulation for your information.

California ARB Regulatory Update January 2010


Attention ARA of California Rental Companies

This is a reminder of the Aug. 1, 2009, deadline for all small fleets to report their off-road diesel vehicles to ARB.

If you have entered your fleet data in DOORS, but not selected "Request Review," you must do so prior to 11:59 p.m. on Aug. 1, 2009, to meet the deadline. Large or medium fleets should have requested a review by April 1, 2009, and June 1, 2009, respectively, but if they have not, ARB staff encourages them to do so as soon as possible. 

Requesting a review sends your information to ARB staff. They will review the data and, if there are no significant errors apparent, assign Equipment Identification Numbers to your fleet.

The option to request a review is on the second dropdown menu immediately after logging into DOORS. It is the very last option below "Enter fleet data online."

If you have questions, please e-mail or call 877-59-DOORS.
