1 Overview of the AB 939 Diversion Rate Measurement System Presented by:

2 Generation Based Quantification Method Used for Measuring Diversion Generation = Disposal + Diversion Diversion Rate = Diversion Generation Diversion Rate = Diversion Disposal + Diversion

3 Adjustment Method More People? More Jobs? More Sales? More Waste Generated CIWMB’s “ADJUSTMENT METHOD” Standard Diversion Rate Calculation PRC PRC & Base Year Generation Tons Calculated Reporting Year Generation Tons

4 CIWMB “Adjustment Method” Generation = Disposal + Diversion Reporting Year Generation Di sp os al Disposal (DRS) Calculated Diversion 100 % Actual Disposal Tons Measured by DRS =

5 Why Change the System? Too much emphasis on numbers instead of program implementation Untimely & Complex –18-24 mo. for final estimated diversion rates Stakeholders wanted the system changed 5

6 Benefits of SB 1016 Focus on program implementation Increases accuracy, simplicity and timeliness of measurement system Accounts for growth (Caution..!) Saves jurisdictions money and time by eliminating complex formulas 6

7 Provides data earlier for jurisdictions to assess program implementation Disposal number is a factor to consider Does not determine compliance Evaluation focused on how jurisdictions are implementing their programs Increases CIWMB staff field presence to provide technical assistance Benefits of SB

8 Calculating the 50% Equivalent Per Capita Disposal Target Use jurisdiction-specific average of per capita generation rates Divide average per capita generation rate by 2 to get disposal a jurisdiction would have disposed if it was exactly 50% diversion Baseline/target is jurisdiction-specific 8

9 10.0 lbs /person /day Base Period Generation (All Disposal + All Diversion) 50% Diversion Rate = 50% Equivalent Per Capita Disposal Target 5.0 lbs /person /day 50% Per Capita Disposal Target (50% of Base Generation) The 50% per capita disposal target is the amount of disposal a jurisdiction would have had during the base period if it had been exactly at a 50% diversion rate. 9

10 Annual Per Capita Disposal Rate A measure of disposal during calendar report year Expressed in Pounds per Person per Day (PPD) Disposed Disposal Tons x 2000 lbs per ton ÷ Population ÷ 365 = PPD Disposed (pounds) (person) (day) 10
