Maximum Allowable Disposal Facts

1. Jurisdictions must use the estimated reporting year generation amount calculated by the Board-approved Adjustment Method to calculate a maximum allowable disposal in each reporting-year.
2. Generation equals disposal plus diversion. To meet diversion rate requirements, the estimated 1995 generation (100%) = maximum allowable disposal (75%) + diversion goal (25%). To meet diversion rate requirements the estimated 2000 generation (100%) = maximum allowable disposal (50%) + diversion goal (50%).
3. Starting in 1995, 25% is to be diverted, so no more than 75% can be disposed. Starting in 2000, 50% is to be diverted, so no more than 50% can be disposed.
4. The Board may have granted a reduction in the diversion rate requirement for rural jurisdictions in 1995, and may grant a reduction for any jurisdiction in 2000 (refer to PRC Section 41785).
5. If a jurisdiction does not have a Board-approved reduced diversion rate requirement, then it will multiply its estimated reporting year generation amount by 0.75 beginning in 1995, and by 0.50 beginning in 2000.
6. If a jurisdiction has a Board approved reduced diversion rate requirement, then it will use:
              100 % - reduced diversion rate percentage = maximum allowable disposal percentage.
                        (For example, 100% - 15% = 85% or 0.85)
7. The calculated maximum allowable disposal will be compared with the actual Reporting-year Disposal to determine the diversion rate achieved.
8. This process does not correct for base-year problems, disposal reporting problems, or changes in conditions not corrected by the adjustment method.
