months within the 12-month reporting period. Track waste generation monthly and include the material type and weight of all nonhazardous solid materials.

Track or estimate variations in materials management that occur outside the reporting period, such as seasonal collection or intermittent waste streams.

Calculate waste diversion by tracking the amount of materials (by weight) diverted from landfills and incineration. For diverted materials, specify the diversion method (reduce, reuse, recycle, compost, etc.). If material quantities are estimated, provide the methodology and/or source references used to make calculations. If actual weights are unavailable for certain material types or hauling methods, volume-to-weight conversion average values can be used.

To calculate the overall diversion rate, divide the weight of materials diverted by the total weight of materials generated for the same reporting period. Account for seasonal collection or intermittent waste streams within the calculations. See Equation 1 for the waste diversion calculation:
