insurance company associated with the engine. Maintenance checks and readiness testing of such units is limited to 

100 hours per year. There is no time limit on the use of emergency stationary ICE in emergency situations. Anyone 

may petition the Administrator for approval of additional hours to be used for maintenance checks and readiness 

testing, but a petition is not required if the owner or operator maintains records indicating that Federal, State, or 

local standards require maintenance and testing of emergency ICE beyond 100 hours per year. For owners and 

operators of emergency engines meeting standards under 40 CFR Part 60.4205, any operation other than emergency 

operation, and maintenance and testing as permitted in this section, is prohibited.

(iv) If the stationary CI internal combustion engine is an emergency stationary internal combustion engine, the owner or 

operator is not required to submit an initial notification. Starting with the model years in table 5 of 40 CFR Part 60, 

Subpart IIII, if the emergency engine does not meet the standards applicable to non-emergency engines in the 

applicable model year, the owner or operator must keep records of the operation of the engine in emergency and 

non-emergency service that are recorded through the non-resettable hour meter. The owner must record the time of 

operation of the engine and the reason the engine was in operation during that time.
