ORIGINAL BASE YEARS

• 1990 / 1991
• Generation study quantified generation for that
  year
• Generation (disposal diversion)
• Used to select programs to achieve diversion
  mandates

3
ORIGINAL MEASUREMENT

• Generation studies required in 1995 and 2000 to
  determine compliance
• 1992 legislation eliminated generation study
  requirement and established standard disposal
  reduction measurement system

4
CURRENT MEASUREMENT

• Disposal Reduction Measurement System
• Base-Year Generation
• Estimated Reporting-Year Generation
• Maximum Allowed Disposal
• Reporting-Year Disposal

BASE YEAR INACCURACIES

• Measurement Accuracy Issues Working Group
• Disposal
• Diversion
• Measurement System

11
BOARD APPROVED METHODS TO IMPROVE BASE-YEAR
ACCURACY

• Base-Year Corrections
• Use Annual Generation Based (disposal
  diversion) Analysis
• Establish More Current Base Year

12
BASE YEAR CORRECTIONS

• Diagnose the problem
• Quantify a correction
• Use Board-approved methodology
• Meet specified criteria
• No corrections to base year data more than three
  years old

13
GENERATION STUDIES

• Annual Generation Study
• Annual estimate of solid waste generation tonnage
  (diversion tonnage disposal tonnage)
• Does not use base-year generation data
• Can be done each year to determine reporting-year
  diversion rate

14
GENERATION STUDIES

• New Base-Year Generation Study
• Estimate of solid waste generation tonnage
  (diversion tonnage disposal tonnage)
• Officially change base-year generation tonnage
• Use new base-year generation tonnage as basis for
  future goal measurement

15
GENERATION STUDIES

• Benefits
• Improve understanding of the waste stream
• Facilitate diversion program selection, planning
  implementation
• Monitor and evaluate diversion programs
• Assess needs of the non-residential sector
• Increase awareness of diversion programs
• Develop exemplary model programs for peer
  matching
• Identify potential sources of manufacturing
  feedstock for local recycling market development
  zone businesses
• Tools
• Office of Local Assistance staff
• Diversion Study Guide
• Certification forms (LG Central Library)
• Infocycling articles

16
GENERATION STUDY DATA

• Disposal Data
• CIWMB Disposal Reporting System (DRS)
• Disposal Correction
• Reporting year disposal tonnage modification
  request and certification

17
GENERATION STUDY DATA

• Diversion
• Jurisdiction diversion programs
• Residential
• Non-residential
• Third-party recycling
• Non-residential waste audits

18
DIVERSION DOCUMENTATION

• Base Year Modification Request Certification
• Non-extrapolated
• Extrapolated
• Hauling reports
• Residential
• Non-residential
• Third-party recycling reports
• Disposal Reporting System
• Alternative Daily Cover

• Facility records
• Landfill
• Material Recovery Facility (MRF)
• Composting
• Biomass/Transformation
• Waste Water Treatment
• Biomass tonnage report
• Non-residential waste audit survey forms

19
DIVERSION DATA REVIEW

• Diversion activity
• Normally disposed
• Quantification methodology
• Restricted waste criteria
• Representativeness

20
ON-SITE DIVERSION VERIFICATION

• Top ten non-residential waste audits
• Overview of staff review questions
• Attachment 3 (staff-recommended
  deductions/additions to generation tonnage)
• Confer with jurisdiction

21
Generation Study Agenda Items

• Agenda Item
• Attachment 1 Diversion program listing
• Attachment 2a Generation study data as
  submitted by jurisdiction
• Attachment 2b Staff recommended
  generation study data
• Attachment 3 Verification findings (listing of
  any generation tonnage additions/deductio
  ns)
• Attachment 4 Resolution

22
BASE YEAR STATISTICS

• Approximately 210 jurisdictions still use
  original (or corrected) base year
• Approximately 15 annual generation studies
• Approximately 30 new base-year generation studies
  anticipated (2003, 2004 or 2005)
