The CPI for any calendar year is the average of the CPI for all-urban consumers published by the
Department of Labor, as of the close of the 12 month period ending August 31 of each calendar
st
year, as prescribed by 40 C.F.R. § 51.360(a)(7)(i). The revision of the CPI that is most consistent
with the CPI for calendar year 1989 shall be used, as prescribed by 40 C.F.R. § 51.360(a)(7)(ii).
8. repair expenditures exceed the following limits:
a. $750 for vehicles five model years old or newer;

Beginning January 1, 2010, the expenditure limits in 310 CMR 60.02(17)(c) shall be
subject to automatic annual adjustment. On January 1, 2010, the expenditure limit in
310 CMR 60.02(17)(c)8.a. shall be adjusted by the percentage, if any, by which the

is no longer available for sale;
3. repairs to a vehicle to correct an engine switch that does not meet the requirements
of 310 CMR 60.02(12)(d);
4. repairs to an OBD system to correct its failure to communicate with emission

operation;
6. repairs to an OBD system to meet minimum test criteria for readiness, except that if
it was necessary to replace the vehicle’s powertrain control module to meet minimum test
criteria for readiness and the vehicle failed upon reinspection because the malfunction
indicator light was commanded by the OBD system to be illuminated, then ½ of the cost
for such replacement may be combined with the repairs appropriate for the diagnostic
trouble code(s) that caused the malfunction indicator light to be commanded on by the
OBD system to meet the applicable waiver cost limit;
7. repairs under any warranty;
8. repairs that are subject to a manufacturer’s recall;
9. repairs unrelated to emissions performance or inappropriate for the diagnostic trouble
