 Subject:
Switcher Locomotive Flexibility

Dear Don and Chuck: Back in September Christine Ueno of MTU Detroit Diesel wrote to you regarding an apparent error in the regulations that provide manufacturers with the flexibility to use certified nonroad engines in switcher locomotives. I am writing on behalf of EMA to follow up on this issue.
 
More specifically, under 40 CFR section 1033.150(e), engine manufacturers may produce for use in switch locomotives nonroad engines certified to the emission standards under Parts 89 or 1039. However, under section 1033.625(a)(2), locomotive manufacturers may only use certified nonroad engines in their switch locomotives where the nonroad emission standards under Parts 89 or 1039 "are numerically lower than the applicable locomotive standards." The problem is that the nonroad CO standard under Part 1039 is not lower than the CO limit under Part 1033. As a result, it appears that it will be impossible for switcher locomotive manufacturers to utilize the intended flexibility under the regulations. This is likely to become a significant issue if not corrected (presumably by a technical amendment) in the near future.
 
Accordingly, please let us know where this issue stands, how the Agency intends to address it, and the anticipated timeline for the needed correction. Thank you. Tim French.
