a. through e. beloware satisfied:
a. The APCO shall be notified in writing or by fax at (805) 781-1002 within seventy two(72) hours of a permitted engine being replaced with a qualified temporary engine.The notification shall include the replacement engines make, model, ratedhorsepower, engine family number, current engine hour meter reading,manufacturer's particulate matter and oxides of nitrogen (NOx) emission rates ingrams per horsepower-hour (g/hp-hr) and the reason for the replacement.
b. The permitted engine is in need of routine repair or maintenance and is returned toits original service within 180 days of installation of the temporary engine.c. The temporary replacement engine has the same or lower manufacturer ratedhorsepower and same or lower potential to emit of particulate matter and Oxides ofNitrogen (NOx) as the permitted engine that is being temporarily replaced.

Uponwritten request, the APCO may approve a replacement engine with a larger ratedhorsepower than the permitted engine if the proposed temporary engine hasmanufacturer guaranteed emissions less than or equal to the permitted engine or ifthe engine meets current permitting requirements.
