Incident Considerations Knowledge of Products involved Knowledge of container carrying product Identify sensitive receptors and critical

structures around scene Understanding ICS and Unified Command Work to provide value to the outcome and

rapid resolution of the incident

Arrival on Scene

Page 4: Response Strategies For Ethanol and Blended Fuels

Ethanol Properties:

Fire hazard greatest threat. Largest volume flammable liquid in rail

and highway transit becoming more prevalent in barges and water transit

Completely miscible in water

Page 5: Response Strategies For Ethanol and Blended Fuels

Ethanol Properties (continued):

Page 6: Response Strategies For Ethanol and Blended Fuels

Ethanol Blended Fuels

Ethanol blends such as E-95, E-85, and various blends of Gasohol reduce the total consumption of gasoline and therefore it is understandable, that in transit this reduction in total volume of gasoline reduces the environmental impact proportionately to the blends ratio of ethanol.

Open Water Response

Gasoline film formed on the water surface as a result of ethanol/gasoline blend spill can be treated as pure gasoline spill.

Environmental impacts of dissolved ethanol can be reduced by introducing additional volume of clean water (if possible) and increasing water mixing (aeration).

Monitoring and sampling of ethanol plume will be a most likely response scenario.

Ground Water Spill

In ground water, the abiotic mechanisms for the attenuation including sorption, volatilization, and abiotic degradation will not contribute substantially to the decreased mobility or loss of ethanol in aquifers.

Therefore, the fate and transport of ethanol will primarily be controlled by biodegradation and dilution.

Page 9: Response Strategies For Ethanol and Blended Fuels

Ground Water Cleanup

In case of underground spill of ethanol/gasoline blend, cleanup strategies that stimulate biodegradation under anaerobic conditions should be considered.

The most common engineered bioremediation approaches used for cleanup are aerobic, introducing oxygen to stimulate biodegradation. Applying sufficient oxygen to meet the high oxygen demand exerted by ethanol will likely be technically difficult and prohibitively expensive.

Open Water Spill

Standard gasoline and water are almost completely immiscible. Ethanol is infinitely miscible with water.

Ethanol/gasoline blend released in an aquatic system will rapidly partition leaving hydrocarbon film on the water surface and ethanol dissolving in the water column.

In a high-energy environment ethanol may act as a weak surfactant and facilitate dispersion of hydrocarbons into water column.

Ethanol can be toxic to aquatic life at high concentrations.

Ethanol and Blended Fuels

Ethanol is degradable and can be stripped from static water columns as well as porous soil regions.

Rapid implementation of an aeration strategy is successful in dealing with elevated chemical oxygen demand (COD) and biological oxygen demand (BOD) in bodies of water.

What is our Plan?

What do you see as the incident priorities? Should the fire or potential fire issue be

addressed at this point? Can we extinguish some and let some burn? Does the Fire Department have the proper

equipment and foam to effectively fight this fire?

What can be done?

Producers Support

What resources are needed from the Producer?

What role does the producer play in the ICS system? Liaison? Technical Specialist?

Product knowledge that the producer can provide can be the difference in the incident.

Firefighting Considerations

Foam? What kind, and how much? Alcohol Resistant Foam is required.

Surgical application a must Pre-cooling of vessel and post-cooling

the key to successful extinguishment. Less than 5 gallons of AR/AFFF used

to extinguish fires in each railcar.

Regulatory discussion

What environmental issues do you see with this incident?

What are the priorities? What impact to the river can be

expected? How would this differ in a still body of

water and how can it be mitigated quickly?
