Stationary engines used for peak shaving are not considered emergency stationary engines.
Stationary engines used to supply power to an electric grid or that supply power as part
of a financial arrangement with another entity are not considered to be emergency engines.
Emergency stationary ICE may be operated for the purpose of maintenance checks and
readiness testing, provided that the tests are recommended by Federal, State or local
government, the manufacturer, the vendor, or the 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 engines in emergency
situations. The owner or operator 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. Emergency
stationary ICE may operate up to 50 hours per year in non-emergency situations, but those
50 hours are counted towards the 100 hours per year provided for maintenance and testing.
The 50 hours per year for non-emergency situations cannot be used for peak shaving or
to generate income for a facility to supply power to an electric grid or otherwise supply
power as part of a financial arrangement with another entity. For owners and operators of
emergency engines, any operation other than emergency operation, maintenance and
testing, and operation in non-emergency situations for 50 hours per year, as permitted
above is prohibited.
