(1) “Affiliate or Affiliation” refers to a relationship of direct or indirect control or shared interests between the subject business and another business.
(2) “Alternative Fuel” means natural gas, propane, ethanol, methanol, or advanced technologies that do not rely on diesel fuel, except as a pilot ignition source at an average ratio of less than 1 part diesel fuel to 10 parts total fuel on an energy equivalent basis. Alternative fuels also means any of these fuels used in combination with each other or in combination with other non-diesel fuels. Alternative-fueled engines shall not have the capability of idling or operating solely on diesel fuel at any time.
(3) “Alternative-Fueled Engine” means an engine that is fueled with a fuel meeting the definition of alternative fuel.
(4) “Alternative Diesel Fuel” means any fuel used in diesel engines that is not commonly or commercially known, sold or represented as No. 1-D or No. 2-D, pursuant to the specification for Diesel Fuel Oils D975-81, 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. Examples of alternative diesel fuels include, but are not limited to, biodiesel, Fischer Tropsch fuels, and emulsions of water in diesel fuel. Natural gas is not an alternative diesel fuel. An emission control strategy using a fuel additive will be treated as an alternative diesel fuel based strategy unless:
(A) The additive is supplied to the vehicle or engine fuel by an on-board dosing mechanism, or
(B) The additive is directly mixed into the base fuel inside the fuel tank of the vehicle or engine, or
