17. What is a Portable Engine?
An engine designed and capable of being carried or moved from one location to another. Indicia of portability include, but are not limited to, wheels, skids, carrying handles, dolly, trailer, or platform. For the purposes of this regulation, dredge engines on a boat or barge are considered portable
The engine is not portable if:
The engine or its replacement is attached to a foundation, or if not so attached, will reside at the same location for more than 12 consecutive months. The period during which the engine is maintained at a storage facility shall be excluded from the residency time determination. Any engine, such as a back-up or stand-by engine, that replace engine(s) at a location, and is intended to perform the same or similar function as the engine(s) being replaced, will be included in calculating the consecutive time period. In that case, the cumulative time of all engine(s), including the time between the removal of the original engine(s) and installation of the replacement engine(s), will be counted toward the consecutive time period; or
the engine remains or will reside at a location for less than 12 consecutive months if the engine is located at a seasonal source and operates during the full annual operating period of the seasonal source, where a seasonal source is a stationary source that remains in a single location on a permanent basis (at least two years) and that operates at that single location at least three months each year; or
the engine is moved from one location to another in an attempt to circumvent the portable residence time requirements.
What is a Dual-fuel Diesel Pilot Engine? An engine that uses diesel fuel as a pilot ignition source at an annual average ratio of less than 5 parts diesel fuel to 100 parts total fuel on an energy equivalent basis.
What is Tactical Support Equipment? Equipment using a portable engine, including turbines, that meets military specifications, owned by the U.S. Department of Defense and/or the U.S. military services or its allies, and used in combat, combat support, combat service support, tactical or relief operations, or training for such operations. Examples include, but are not limited to, engines associated with portable generators, aircraft start carts, heaters and lighting carts.

20. What is an Alternative Diesel Fuel?
Any fuel used in a compression ignition (CI) engine that is not, commonly or commercially known, sold or represented by the supplier as diesel fuel No. 1-D or No. 2-D, pursuant to the specifications in ASTM Standard Specification for Diesel Fuel Oils D975-81, or an alternative fuel, and does not require engine or fuel system modifications for the engine to operate, although minor modifications (e.g., recalibration of the engine fuel control) may enhance performance. An emission control strategy using a fuel additive will be treated as an alternative diesel fuel based strategy unless:
(1) the additive is supplied to the engine fuel by an on-board dosing mechanism, or
(2) the additive is directly mixed into the base fuel inside the fuel tank of the engine, or
(3) the additive and base fuel are not mixed until engine fueling commences, and no more additive plus base fuel combination is mixed than required for a single fueling of a single engine.
What is a Fuel Additive? Any substance designed to be added to fuel or fuel systems or other engine-related systems such that it is present in-cylinder during combustion and has any of the following effects: decreased emissions, improved fuel economy, increased performance of the engine; or assists diesel emission control strategies in decreasing emissions, or improving fuel economy or increasing performance of the engine. Fuel additives used in conjunction with diesel fuel may be treated as an alternative diesel fuel.
What is a Low-Use Engine? A portable diesel-fueled engines that operates 80 hours or less in a calendar year.

38. What is an Emergency Standby Engine?
"Emergency Standby Engine" means a stationary engine that meets the criteria specified in (A) and (B) and any combination of (C) or (D) or (E) below:
(A) is installed for the primary purpose of providing electrical power or mechanical work during an emergency use and is not the source of primary power at the facility; and
(B) is operated to provide electrical power or mechanical work during an emergency use; and
(C) is operated under limited circumstances for maintenance and testing, emissions testing, or initial start-up testing, as specified in sections (a),(b), and (c); or
(D) is operated under limited circumstances in response to an impending outage, as specified in sections (a),(b), and (c); or
(E) is operated under limited circumstances under a DRP as specified in section (c).
What is Emergency Use?
“Emergency Use" means providing electrical power or mechanical work during any of the following events and subject to the following conditions:
(A) the failure or loss of all or part of normal electrical power service or normal natural gas supply to the facility:
1. which is caused by any reason other than the enforcement of a contractual obligation the owner or operator has with a third party or any other party; and
2. which is demonstrated by the owner or operator to the district APCO's satisfaction to have been beyond the reasonable control of the owner or operator;
(B) the failure of a facility's internal power distribution system:
(C) the pumping of water or sewage to prevent or mitigate a flood or sewage overflow;
(D) the pumping of water for fire suppression or protection;
(E) the powering of ALSF-1 and ALSF-2 airport runway lights under category II or III weather conditions;
(F) the pumping of water to maintain pressure in the water distribution system for the following reasons:
1. a pipe break that substantially reduces water pressure; or
2. high demand on the water supply system due to high use of water for fire suppression; or
3. the breakdown of electric-powered pumping equipment at sewage treatment facilities or water delivery facilities; or
(G) the day-of-launch system checks and launch tracking performed (in parallel with grid power) by the United States
Department of Defense at Command Destruct sites (also known as "CT" sites) that occur within the 24-hour time
period associated with the scheduled time of the launch.

Reporting Provisions for Exempted Agricultural Emergency, Prime, and Nonagricultural Emergency Engines.
An owner or operator of an agricultural emergency standby generator set engine subject to section (a) or an engine subject to sections (d) or (j) shall keep records of the number of hours the engines are operated on a monthly basis. Such records shall be retained for a minimum of 36 months from the date of entry. Record entries made within 24 months of the most recent entry shall be retained on-site, either at a central location or at the engine's location, and made immediately available to the District staff upon request. Record entries made from 25 to 36 months from the most recent entry shall be made available to District staff within 5 working days from the district's request.
Reporting Requirements for Emergency Standby Engines.
(1) Starting January 1, 2005, each owner or operator of an emergency standby diesel-fueled Cl engine shall keep records and prepare a monthly summary that shall list and document the nature of use for each of the following:
(A) emergency use hours of operation;
(B) maintenance and testing hours of operation;
(C) hours of operation for emission testing to show compliance with sections (a)(3) and (b)(3);
(D) initial start-up testing hours;
(E) if applicable, hours of operation to comply with the requirements of NFPA 25;
(F) hours of operation for all uses other than those specified in
sections (g)(1)(A) through (D) above; and
(G) the fuel used.
1. For engines operated exclusively on CARB Diesel Fuel, the owner or operator shall document the use of CARB Diesel Fuel through the retention of fuel purchase records indicating that the only fuel purchased for supply to an emergency standby engine was CARB Diesel Fuel; or
2. For engines operated on any fuel other than CARB Diesel Fuel, fuel records demonstrating that the only fuel purchased and added to an emergency standby engine or engines, or to any fuel tank directly attached to an emergency standby engine or engines, meets the requirements of section (b).
(2) Records shall be retained for a minimum of 36 months. Records for the prior 24 months shall be retained on-site, either at a central location or at the engine's location, or at an offsite central location within California, and shall be made immediately available to the District staff upon request.
