Sec. 85.1414  Alternative test procedures.

    As a part of the certification process, as set forth in 
Sec. 85.1406, a certifier may request that the Agency approve an 
alternative test procedure, other than the heavy-duty engine Federal 
test procedure, to show compliance with the 25 percent reduction in 
particulate matter emissions as noted in Sec. 85.1403(b)(2)(i). The 
alternative test may be a chassis-based test, but the alternative test 
shall be representative of in-use urban bus operation. The requestor 
shall supply relevant technical support to substantiate its claim of 
representativeness. Upon an acceptable showing that an alternative test 
is representative of in-use urban bus operation, the Agency shall 
determine whether to set such alternative test procedures through 
rulemaking. The provisions of the certification process apply to such a 
request for alternative procedures.

    Effective Date Note: Information collection requirements in 
Sec. 85.1414 have not been approved by the Office of Management and 
Budget (OMB) and are not effective until OMB has approved them.
