On June 12, 2018, the Bureau of Labor Statistics released the May 2018 Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) which established the Private Transportation Index at 210.730, an increase from the February 2018 Index of 203.13. As a result, the Equipment Maintenance Allowance (EMA) for rural carriers will increase by 3.0¢ to 74.0¢ per mile.
This EMA rate will be effective July 7, 2018 (Pay Period 15-2018).
