What is An Emergency Outage?
An emergency is defined as the loss of power from the local utility. For additional definitions of what event qualifies as an emergency see 17 CCR 93115.4(a)(30 ) page 9 for diesel engines and Rule 12 (c)(4) on page 2 for diesel and non-diesel engines.
Engine Compliance Tips
1. Standby engines have a limit on the number of hours the engine can be operated for testing and maintenance in every calendar year.
2. An operation log must be maintained.
3. Engines may have limits on the time it can operate during the day (for example, the engine may prohibited from operating for testing and maintenance during school hours if located within 500 feet of a school).
4. Engines owners are required to perform annual maintenance on the engine (and associated control equipment, if installed). Diesel engines are required to maintain records on site of the type of diesel fuel (i.e., CARB diesel) used in the engine.
In the event your engine or equipment associated with the engine malfunctions and you are in violation of a District rule or regulation you may have had an equipment breakdown.
