EPA is establishing a new category of excluded fuel that has its own set of conditions, some of which overlap with the comparable fuels exclusion. These newly excluded hazardous secondary materials are called "emission-comparable fuel" (ECF). ECF is a hazardous secondary material that, when generated, is handled in such a way that it is not discarded in any phase of management, but rather is handled as a valuable commodity. ECF meets all of the hazardous constituent specifications (over 160) for comparable fuel, with the exception of those for oxygenates and hydrocarbons (constituents which contribute energy value to the fuel). The rule specifies conditions on burning ECF which assure that emissions from industrial boilers burning ECF are comparable to emissions from industrial boilers burning fuel oil. The ECF exclusion also includes conditions for tanks and containers storing ECF to assure that discard does not occur. This final rule is effective January 20, 2009.
