Emergency Diesel Engine Reporting

The VCAPCD issues Permits to Operate to facilities that have emergency standby diesel engines. These permits apply conditions to assure compliance with the California Air Toxic Control Measure (ATCM) for Stationary Diesel Engines and VCAPCD Rule 74.9, Stationary Internal Combustion Engines. Permit conditions set limits, based on the ATCM, for the annual hours of operation for maintenance and testing for each engine.

Companies with stationary emergency standby diesel engines are required to record each engine's hours of operation and maintain logs that differentiate operating hours for maintenance and testing from emergency use for each engine. Records of operation must be summed and submitted to the VCAPCD in a report that is due annually on Feb.15.

A district report form can be used to submit the required data. The form must be signed and can be mailed, faxed or emailed. If the form is faxed or emailed, the original hard copy does not have to be mailed.
