6. Description of content : The California Air Resources Board (CARB) has notified EPA that 
it has adopted a seri es of amendments to its on -highway heavy -duty vehicle and engine 
regulations. The amendments to CARB's in -use compliance program align CARB's program 
with EPA's program in terms of measurement allowances during on -road testing (In -Use 
Amendments). The amen dments to CARB's 2007 and subsequent model year (MY) 
regulation (2007 Amendments) are minor technical amendments regarding mathematical 
expression of emission results and certain compliance flexibilities. The amendments to 
CARB's truck idling requirements (Truck Idling Amendments) clarify that certain vehicles 
are exempt from the new vehicle requirements. By letter dated 27 January 2016, CARB 
submitted a request that EPA grant a full waiver of preemption under section 209(b) of the 
Clean Air Act (CAA), 42 U .S.C. 7543(b) for the In -Use Amendments. CARB separately 
seeks EPA's confirmation that the 2007 Amendments and the Truck Idling Amendments 
are within the scope of prior EPA waiver decisions. This notice announces that EPA has 
scheduled a public hearing con cerning California's request and that EPA is accepting 
written comment on the request.
