CSLB Offers Resources to Help Licensees Stay On Top of Air and Water Regulations

Important deadline quickly approaching for off-road equipment compliance

SACRAMENTO -California's licensed contractors have a responsibility to follow a myriad of rules and regulations covering air and water quality. Staying on top of these regulations can be challenging. The Contractors State License Board (CSLB) has information on two non-profit groups that can help.

This information is especially important because of a quickly-approaching deadline. March 1, 2010 is the first emission-based compliance date for the California Air Resources Board (ARB) off-road equipment regulation for fleets with a total maximum power greater than 5,000 horsepower (hp).

The off-road equipment regulation is aimed at reducing toxic diesel emissions from off-road vehicles, including tractors and bulldozers used in construction. In 2009, all owners of diesel-fueled construction equipment 25 hp and larger were responsible to report their equipment inventory to ARB. They must now display a state-issued Equipment Identification Number on each piece of equipment.

The fines and penalties for not following these and other air and water regulations can be steep. For example, the fines imposed by the ARB can reach $10,000 per day, per vehicle. Violations of the State Water Board's General Construction Permit can add up to $27,500 per day.

CSLB encourages its licensees to learn more from two non-profit organizations that can assist contractors, equipment owners, and builders with the complex rules and regulations: the Construction Industry Air Quality Coalition (CIAQC) and the Construction Industry Coalition on Water Quality (CICWQ). These groups work to help make sure that any new regulations are both technologically sound and economically feasible. Major funding for these two groups is provided by the Construction Industry Advancement Fund and the Fund for Construction Industry Advancement.
