Information includes engine hour meter readings and the reason for operation (e.g. initial engine startup, engine maintenance and testing, and emergency use due to interruption of electrical power).
  • Diesel Engine Operation Log (DOC)
  • Diesel Engine Operation Log (PDF)

These forms may be filled-out by-hand; or alternatively they may be completed electronically. View the Recordkeeping Advisory Notice (PDF).

Location / Timeframe of Records
