1 Scope This publication describes recommended practices for the storing, handling, and fire protection of ethanol and gasoline-ethanol blends from E1 to E15 and from E65 to E100 (used for E85) at distribution terminals and filling stations. Where information exists for gasoline-ethanol blends from E11 to E15, it is shared. Recommended practices for E16 through E69 are not covered because currently these blends are not legal gasolines blends or alternative fuels. There is a general lack of information on the properties of these blends and there are currently no filling station components certified by any nationally recognized testing laboratory for these blends. This document is current at the time of publication, but changes to regulations and listings may affect the accuracy certain recommended practices. See the form in Annex D to provide suggestions for updating or revision. While this publication does not address second or future generation biomass-based alcohols which use feedstocks and manufacturing processes that are different than those employed for current U.S. ethanol supplies, it is unlikely that sugar or cellulosic ethanols will alter the overall recommendations in this RP. Future generation bioethanol fuels may have different properties and the practices described in this publication may not be applicable. When dealing with those fuels, good engineering practices should be employed until this document is updated. This publication does not address ethanol diesel blends. This publication does not address health effects or the remediation of ethanol or gasoline-ethanol blend spills or releases. 2 References 2.1 General The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
3 Definitions and Acronyms 3.1 Definitions For the purposes of this document, the following definitions apply. 3.1.1 alcohol An organic compound containing one or more hydroxyl groups (-OH) bound to a carbon atom. 3.1.2 alternative fuels Ethanol, natural gas, propane, hydrogen, biodiesel, methanol, electricity, and P-Series fuels as defined by the Energy Policy Act of 1992 (EPAct). Synthetic fuels made by the Fischer-Tropsch (coal to liquid) process are also considered alternative fuels. 3.1.3 anhydrous ethanol Neat ethanol that contains less than one percent water. 3.1.4 anhydrous denatured ethanol Fuel ethanol. Neat ethanol with up to five volume percent hydrocarbons added as a denaturant. 3.1.5 API table A liquid measurement table used to correct the metered volume of a blend component to the volume at a standard temperature of 60 °F. Each component or blend of components needs a separate table. 3.1.6 base gasoline Gasoline without ethanol. Base gasoline is sometimes called clear gasoline. 3.1.7 blendstock for oxygenated blending BOB Gasoline refined especially for blending with an oxygenate such as fuel ethanol to produce a gasoline-ethanol blend for commerce. 3.1.8 blend growth The 0.1 % to 0.4 % increase in volume that occurs when gasoline and ethanol are mixed. 3.1.9 clean agent A fire extinguishant that relies on heat absorption and chemical interaction to extinguish fires and mitigate the effects of smoke and flames. It leaves no residue or collateral damage as a result of its use and newer types are safe for use where people are present. 3.1.10 denaturant A hydrocarbon added to neat ethanol to make it unfit for consumption. Suitable denaturants are listed in ASTM D4806.
3.1.11 denatured ethanol E97. See 3.1.18, fuel ethanol. 3.1.12 distribution terminal A facility where base gasoline and fuel ethanol are received by tank truck, railroad tank car, pipeline, barge or tanker and stored in stationary tanks until they are blended and loaded into tank trucks for delivery to bulk plants, filling stations and end-use consumers. 3.1.13 ethanol Ethyl alcohol. Neat ethanol. A straight-chain alcohol with the molecular formula C 2 H 5 OH. 3.1.14 ethanol blend A motor fuel which is a blend of ethanol and gasoline. 3.1.15 EXX The acronym used to describe a blend of XX percent ethanol by volume and gasoline. For example, E10 is 10 % ethanol and 90 % gasoline. 3.1.16 E85 E85 is blended according to ASTM D5798 which covers a fuel blend range which is nominally 75 to 85 volume percent fuel ethanol (Ed75 to Ed85) and 25 to 15 additional volume percent hydrocarbons. Like gasoline specifications, the E85 specification accommodates changes in ambient temperatures according to month and geographic location. During cold weather months in some areas, E85 may contain as low as 65 volume percent ethanol to increase volatility. E85 is also referred to as “nominal E85”. In this recommended practice, the term “E85” will be used to refer to the range of blends specified in ASTM D5798.
