Report Presentation Overview Requirements Facility Selection Methodology Findings Next Steps
CalRecycle Requirements for ADC California Code of Regulations (CCR), Title 14 and 27 • Disposal Reporting System (DRS) Annual Reporting 14 CCR § 18810.9 • Landfill Record Keeping 27 CCR § 20510 (g) • ADC Application State Minimum Standards 27 CCR §20690 (a)(1)
Facility Selection Highest Ratios Reported to DRS in 2012 • Top 10 Sites with Highest Total ADC to Waste Disposed Ratios • ADC to disposal ranges: 494% to 16.7% • Highest Processed Green Material ADC to Waste Ratios • 8 of 15 sites used processed green material • ADC to disposal ranges: 363.9% to 4.9% • Top 5 with highest ADC to waste ratio • ADC to disposal ranges > 25%
Facility Selection - List • Azusa Land Reclamation Co. Landfill • Calabasas Sanitary Landfill • City of Watsonville Landfill • Clover Flat Landfill • L and D Landfill • Olinda Alpha Sanitary Landfill • Pebbly Beach (Avalon) Disposal Site • Top 5 Processed Green Material ADC to Waste Disposed Ratio PotreroHills Landfill • Pumice Valley Landfill • Rock Creek Landfill Scholl Canyon Landfill • Simi Valley Landfill & Recycling Center • Vasco Road Sanitary Landfill • Walker Landfill • Zanker Material Processing Facility
Investigation Methodology - Record Review • Review of DRS Reports • Selection of Sites • Review of Board of Equalization Reports • Reviewing Permit Documents • Solid Waste Facility Permit • Report of Disposal Site Information (RDSI)/ Joint Technical Documents (JTD) • ADC Demonstration Projects • Previous InspectionReports
Investigation Methodology - Facility Review • Facility Inspections • Landfill record review • Site observation of ADC use • Test hole digging • Interviewing Facility Operators • Interviewing LEAs
Findings - Facility Variables • Density of ADC material • Types of ADC Use • Frequency of ADC Use • Amount of waste disposed • Size and Shape of Working/Active Face • Waste in Place Density
Findings • 2 Facilities Likely Over Used ADC • 8 Facilities Mis-reported to DRS • 6 Over-reported ADC: No indications of over-use • 2 Over-used could not be determined • 5 Facilities had No Errors • No record keeping or DRS reporting errors were found • No indications of over use
Findings – Nature of Mis-reporting • Reporting ADC Accepted as ADC Used • Combining ADC Material with Another Recycled Material • Reporting Beneficial Reuse as ADC • Reporting Intermediate Cover as ADC • Including Soil as ADC • Using the Incorrect Conversion Factor (tons to cubic yards) • AppylingUnapproved ADC.
Next Steps • Education and Outreach • LEAs & Operators Training – Fall 2014 State Minimum Standards Training • Development of DRS Outreach Materials • New DRS Reports and Tools on the CalRecycle Website • Enhanced Focus on ADC Use and Record Keeping during CalRecycle’s future 18-month Inspections
