Method #1: Used one of the waste quantity measurement methods specified in 98.463(a)(2)(i): direct mass measurements, direct volume measurements multiplied by waste stream density, mass balance procedures (difference between the mass of process inputs and the mass of process outputs), or the number of loads multiplied by the mass of waste per load based on the working capacity of the vehicle or container.
Method #2: Calculated the average waste disposal rate per Equation TT-2 and calculated the waste disposal quantities for historic years in which direct waste disposal measurements are not available using historical production data per Equation TT-3.
Method #3: Calculated an average annual bulk waste disposal quantity for historic years when waste quantity data as determined by other methods are available consecutively for the most recent disposal years (Equation TT-4a).
Method #4: Calculated an average annual bulk waste disposal quantity for historic years when waste quantity data as determined by other methods are available for sporadic (non-consecutive) years (Equation TT-4b).
