A persistant 'can't intubate, can't oxygenate' crisis despite rocuronium reversal with sugammadex.
Other ether-based oxygenates are likely to suffer fates similar to MTBE as they are also under environmental scrutiny.
Bluewater Network is a strong supporter of renewable fuels, and has endorsed ethanol as the best oxygenate to meet federal requirements.
Ethanol is a renewable fuel oxygenate that provides air quality benefits like MTBE while posing very little threat to water quality.
The groups also urged Congress to allow states to regulate MTBE and other oxygenates. Specifically, they want EPA to grant California s request to set oxygenate limits for its gasoline.
According to Dow Jones, Abraham stressed he does not have "inside knowledge" concerning EPA plans nor does he know when the agency will make a decision regarding the oxygenate waivers.
Several oxygenates other than ethanol could supplant MTBE as the gasoline additive of choice.
Gasoline will remain the largest market for fuel additives, though the ban on the use of MTBE in California and the potential phase out across the US of this oxygenate will result in significant decreases in the gasoline segment, as MTBE is the single largest additive used in gasoline.
Established in 1981, IRI has targeted global refiners, world automakers, fuel oxygenate manufacturers and other fuel industry professionals with information and analysis via custom consulting, multi-client studies and daily market reports delivered electronically.
The list now includes ASTM Fuel B, 30% toluene/70% iso-octane, representing a normal gasoline without additives; ASTM Fuel C, 50% toluene/50% iso-octane, representing a gasoline with high aromatic content; ASTM Fuel D, 40% toluene/60% iso-octane, representing a medium high aromatic content, used mainly in Europe; M 25, 75% ASTM Fuel C/25% methanol representing a "worst case" gasoline containing methanol as oxygenate; FAM fuel, 50% toluene/30% iso-octane/15% di-isobutylene/5% ethanol, a European test fuel representing an aggressive gasoline; and M 15, 85% FAM fuel/15% methanol, a European test fuel representing a "worst case" gasoline containing methanol as oxygenate.
The Pennsylvania Department of Environmental Protection (DEP) said McGinty recommended giving the industry at least three years to develop the infrastructure necessary to meet the federally mandated oxygenate requirement "to prevent any 'backsliding' on the very significant air-quality benefits of reformulated gasoline."
The Renewable Fuels Association (RFA) recently announced it has sent a letter to Environmental Protection Agency administrator Mike Leavitt "strongly rebutting" assertions that granting Clean Air Act oxygenate waivers would help such states as California and New York reduce gasoline prices.
