1 Module 3: Transportation and Transfer of Ethanol-Blended Fuels

2 2 Objective Upon the successful completion of this module, participants will be able to describe how ethanol-blended fuels are transported and transferred and where the most likely points for error in these actions will exist.

3 3 Introduction Essential to quickly & effectively identify presence of ethanol / ethanol-blended fuels at scene of incident Can be challenging because containers in which ethanol is transported not always clearly marked Steps taken to ensure incidents managed effectively

4 4 Transportation and Placarding Gasoline & ethanol- blended fuels transported in same general types of containers & tanks MC-306 / DOT-406 Multiple sizes & compartment configurations Local transportation issues Copyright 2006, TEEX/ESTI

5 Standard MC-306 / DOT-406 Duel axle Capacity: 6,000– 9,500 gallons Custom built 3/8 inch aluminum 1–7 compartments Property of Heil Trailers International, reprinted with permission 5

6 Heavy Duty MC-306 / DOT-406 Tri-axle Capacity: 9,500– 15,000 gallons Custom built 1–7 compartments Property of Heil Trailers International, reprinted with permission 6

7 Michigan-Style MC-306 / DOT-406 Multiple axles Capacity: 13,800 gallons Custom built 5 compartments Property of Heil Trailers International, reprinted with permission 7

8 Truck and Pull MC-306 / DOT-406 Truck tank: –Capacity: 4,000–6,000 gallons –1–4 compartments Trailer tank: –Capacity: 4,000–8,500 gallons –1–5 compartments Custom built Property of Heil Trailers International, reprinted with permission 8

9 Military Refueler Low profile Capacity: 5,000 gallons Single compartment Built to military specifications Air transportable Property of Heil Trailers International, reprinted with permission 9

10 10 Transportation and Placarding DOT: –Classifies according to primary danger –Assigns standardized symbols to identify classes Ethanol & ethanol-fuel blends are flammable liquids Copyright ERG

11 Transportation and Placarding 11 Flammable tanker placards: –Lower ethanol concentrations up to & including E-10 (E-01 to E-10) blended fuels: UN 1203 –E-85 (E-11 to E-94) blended fuels: UN 3475 –E-95, E-98 (E-95 to E-99) blended fuels: UN / NA 1987 –E-100: UN 1170 Copyright ERG

12 Transportation and Placarding October 1, 2008: –U.S. DOT, Pipeline and Hazardous Materials Safety Administration (PHMSA) issued final rule creating a new proper shipping name & placard for ethanol-blended fuels with a percentage higher than 10% but lower than 95% (E-11 to E-94) 12

13 Ethanol Proper Shipping Names Ethanol Concentration Preferred Proper Shipping Name E-1 to E-10 Gasohol (UN 1203) or Gasoline (UN 1203) E-11 to E-94 Ethanol & gasoline mixture (UN 3475) E-95 to E-99 Denatured alcohol (NA 1987) or Alcohols n.o.s. (UN 1987) E-100 Ethanol (UN 1170) or Ethyl alcohol (UN 1170) 13

14 Transportation and Placarding April 22, 2009: –EPA received a waiver to lift arbitrary regulatory cap on ethanol from a 10% blend of ethanol to a 15% blend of ethanol in our gas supply; must approve / disapprove by December 1, 2009 –Current cap dates back to 1970s –If approved, DOT-PHMSA will decide placarding; current debate is to placard pure hydrocarbon gasoline with UN 1203 & E-1 to E-94 ethanol-blended fuels with placard UN

15 Transportation and Placarding DOT 111 rail car: –Non-pressure general tank car –Current maximum capacity 34,500 gallons Copyright 2009, IAFC 15

16 16 Transportation and Placarding Rail tanks identified similarly Pressure & vacuum relief devices same as currently found on gasoline-style transport tankers Bottom loaded & unloaded by standard 4-inch quick connect / direct connections

17 17 Transportation and Placarding Valving internal to tanks with breakaway piping & remote shut-off controls Vapor recovery systems same as currently found on roadway gasoline tankers

21 21 Transportation and Placarding Most fuel-grade ethanol (E-98, E-95) transported by rail: –Some by waterway & very small amounts by pipeline –Pipeline concern: corrosiveness –pH between 5 & 6 (slightly corrosive) Storage depots with no access to rail receive it by road tankers: –Trans-loading

22 22 Transportation and Placarding NFPA 704 diamond: –Uses colors, numbers, & special symbols to indicate presence of hazardous materials –Higher number = greater hazard

23 NFPA 704 Diamond 23 Copyright 2008, TEEX/ESTI

24 24 Transportation and Placarding NFPA 704 diamond: –Health: Blue –Flammability: Red –Reactivity: Yellow –Special: White (special notice)

25 25 Transportation and Placarding NFPA diamond for E-100, E-98, E-95, E-85, & E-10 (gasoline): –1: Blue health square: slight to moderate irritation –0: Reactivity yellow square –3: Flammability red square: high flammability with ignition likely under most conditions –No commonly accepted special character (white)

27 27 Transportation and Placarding Most hazardous materials incidents occur during transportation & transfer operations Be aware of areas / routes where large shipments of ethanol & ethanol-blended fuels routinely pass Fuel-grade ethanol (E-98, E-95) now leading single hazardous material transported by rail Some refineries now shipping fuel fully blended

28 28 Transportation and Placarding Most of Midwest & other ethanol production facilities have access to rail sidings, many bulk storage fuel depots do not have rail sidings: –Much of the fuel-grade ethanol is trans-loaded to tanker trucks for distribution to bulk storage facilities via highways

29 29 Transportation and Placarding Placards able to indicate high-concentration ethanol-blended fuels: –Does not distinguish between gasoline & E-10 gasohol –E-10 requires AR foam for emergency response

30 Transportation and Placarding TRANSCAER: –Voluntary effort –Founded by Union Pacific & Dow Chemical –Members –Resources may include: 30

31 31 Activity 3.1 Ethanol Spill Emergency Purpose: –To allow participants to determine the hazards associated with an ethanol emergency.

32 32 Summary Variety of sources for information about chemicals involved in spill / fire incidents: –MSDS –UN numbers –DOT placards –NFPA 704 placards Fuel-grade ethanol (E-98, E-95) become leading hazardous material transported by rail: –Transfer commonly occurs via highways
