Overview of the AB 939 Diversion Rate Measurement System
Presented by:
Generation Based Quantification Method Used for Measuring Diversion
Generation = Disposal + Diversion
Diversion Rate = Diversion Generation
Diversion Rate = Diversion
Disposal + Diversion
Adjustment Method
More People?More Jobs?More Sales?
More Waste Generated
CIWMB’s “ADJUSTMENT METHOD”Standard Diversion Rate Calculation
PRC 41781PRC 41780.1 & 41780.2

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

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
• Provides data earlier for jurisdictions to assess program implementation
• Disposal number is a factor to considerDoes not determine compliance
• Evaluation focused on how jurisdictions are implementing their programs
• Increases CIWMB staff field presence to provide technical assistance
Benefits of SB 1016

Calculating the 50% Equivalent Per Capita Disposal Target
• Use jurisdiction-specific average of 2003-2006 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

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 CapitaDisposal 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.

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)
