High Occupancy Vehicle Exemption Proposed Rule (May 24, 2007)
The 2005 transportation act known as “SAFETEA-LU” directs EPA to advise states on defining low emission and energy efficient vehicles that may use a High Occupancy Vehicle (HOV) lane with fewer than the required number of occupants. This action guides states that seek an exemption from existing HOV requirements for vehicles certified as “low emission and energy efficient.” SAFETEA-LU was originally scheduled to sunset on September 30, 2009 but Congress extended it through 2010 as part of the Hiring Incentives to Restore Employment (HIRE) Act which was signed into law on March 18.
EPA has issued a notice of proposed rulemaking that would establish criteria for exemptions to the current HOV lane requirements. EPA has established a public docket for this action (Docket No. EPA-HQ-OAR-2005 0173). To view the docket, go to www.regulations.gov. (NOTE: To access the docket from this link, select Advanced Search, then Docket Search, and then type EPA-HQ-OAR-2005 0173 as the Docket ID.)

This Web site is sponsored by the U.S. Department of Energy (DOE) and provides further information on Green Racing. EPA works with DOE to ensure that manufacturers and racing teams minimize the energy and petroleum used and greenhouse gases (GHG) that can be emitted from some racing vehicles. - Best Workplaces for Commuters
The Best Workplaces for Commuters program was established by EPA and DOT and is now administered by the Center for Urban Transportation Research (CUTR), to recognize employers who voluntarily meet the National Standard of Excellence in employer-provided commuter benefits. Providing commuter benefits helps employers address limited or expensive parking, reduce traffic congestion, improve employer recruiting and retention, and minimize the environmental impacts associated with drive-alone commuting. The Web site provides information on the program for employers, employees, supporters, and commuters. - Mobile Source Program
