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 Consumer Price Index ("CPI") for the preceding calendar year differs from the CPI of 1989 and the adjusted expenditure limit shall be rounded to the nearest $5.00.2 The expenditure limit in 310 CMR 60.02(17)(c)8.b. shall then be adjusted by subtracting $100 from the adjusted expenditure limit in 310 CMR 60.02(17)(c)8.a. The expenditure limit in 310 CMR 60.02(17)(c)8.c. shall then be adjusted by subtracting $200 from the adjusted expenditure limit in 310 CMR 60.02(17)(c)8.a. The Department will publish these adjusted expenditure limits on the web site for the Enhanced Emissions and Safety Test Program.
