On May 3, 2011, EPA issued a “Dear Manufacturer Letter” (CISD-11-06) which updates the agency's Cross-Border Sales Policy pertaining to sales of “California vehicles” for model years 2011 and beyond.
Under this policy, manufacturers may introduce into commerce 2011 and beyond model year vehicles certified by California and EPA to California regulations, but not federal regulations, into California and any of “the 177 states” (i.e., states that have adopted and placed into effect the CARB regulations for a vehicle class or classes in accordance with Section 177 of the Clean Air Act). This policy is applicable for vehicles classified by CARB as passenger cars (PC), light-duty trucks (LDT), medium-duty vehicles (MDV), and heavy-duty vehicles (HDV). EPA will not prevent manufacturers from introducing vehicles certified as meeting California regulations into commerce in the states that are not one of “the 177 states” but are contiguous to either California or any of “the 177 states.”
