FRA's accident/incident reporting regulations (49 CFR part 225) require railroads to report certain train accidents that result in damages higher than a specified amount (the "reporting threshold"). Train accidents that yield damages in excess of the reporting threshold are severe enough in nature that FRA wants to capture specific information about those events and use the collected information to identify safety trends. Without the reporting threshold, or some other parameter, railroads would have to report every minor event. FRA periodically reviews the reporting threshold and adjusts it as necessary to accurately maintain comparability between different years of accident data by having the reporting threshold keep pace with any increases or decreases in equipment and labor costs. This approach ensures that each year train accidents involving the same minimum amount of railroad property damage are included in the reportable accident counts. FRA uses two components to calculate the reporting threshold: (1) Surface Transportation Board (STB) wage data for certain railroad employees; and (2) the Bureau of Labor Statistics' (BLS) overall rail equipment cost index (PPI). This rule proposes: (1) a minor technical correction to the mathematical formula (published at appendix B to part 225) FRA uses to periodically adjust the reporting threshold; (2) the use of full-year (12 months) STB wage and PPI equipment price data in the threshold calculation formula (FRA currently uses only 2nd-quarter [3 months] wage and equipment price data in its calculations); and (3) a change in how FRA notifies railroads of adjustments to the reporting threshold. This rule also solicits comment on the feasibility of using a new method to adjust the reporting threshold: time series analysis and forecasted labor and equipment cost data.
