Part 75 monitoring is an allowance trading system, under which affected utility units are allocated "allowances" based on historical fuel consumption and specified emission rates. The allowances can be traded as commodities. To ensure that allowances are consistently valued and to ensure that all of the projected emission reductions are in fact achieved, it is necessary that actual emissions from each affected utility unit be accurately determined. This manual provides a series of questions and answers that can be used on a nationwide basis to ensure that Part 75 emissions monitoring and reporting requirements are applied consistently for all affected sources.
