The Marin County Hazardous and Solid Waste Management Joint Powers Authority (Zero Waste Marin) represents Marin County, 11 incorporated cities or towns within Marin County, and 12 special collection districts that franchise for hauling services, for a total of 24 agencies. R3 was engaged by the Marin County Hazardous and Solid Waste Management Joint Powers Authority (Zero Waste Marin) to assist in its development of a “Materials Flow & Capacity Analysis” in order to improve its regulatory compliance and long-term planning. This project included an analysis of organic waste processing capacity and tool development to evaluate potential organic waste diversion scenarios through year 2025. The primary goal was to improve Zero Waste Marin’s regulatory compliance with state solid waste and recycling requirements and long-term planning.
Key services R3 performed for Zero Waste Marin include:
- Supporting legislative and regulatory compliance, specifically reporting under AB 876 and 901 and planning for organic waste reduction under SB 1383;
- Developing projections for organic waste generation, diversion, and processing capacity in Marin County for a 15-year range; and
- Developing user-friendly Excel tools for Zero Waste Marin staff that enhance Marin County reporting capabilities and facilitate long-term solid waste planning; and
- Producing a clear, concise, and readily digestible report, presentations, and other documents incorporating graphics that communicate relevant policy matters to the Zero Waste Marin Board.
To assist in supporting legislative and regulatory compliance, R3 reviewed the Organics Management Infrastructure Planning Calculator used in the 2017 EAR (for reporting year 2016) and assisted Zero Waste Marin in refining the assumptions and worksheet to determine the need for and availability of organic waste processing capacity. This helped Zero Waste Marin characterize SB 1383 compliance related to a 50% reduction in organic waste disposal from the 2014 level by 2020, and a 75% reduction by 2025. R3 also reviewed Zero Waste Marin’s Excel workbook for CalRecycle State Disposal Reporting System (DRS) reports to identify new hauler and facility reporting needs from AB 901, update the workbook for AB 901 preparedness, and assess the AB 901 data gathering system in order to determine what information Zero Waste Marin should obtain directly from the haulers and facilities for Zero Waste Marin assessment calculations.
R3 reviewed findings of the 2012 Environmental Science Associated (ESA) projections of long-term disposal capacity at Redwood Landfill to verify accuracy of disposal capacity in the ESA projections. Using the ESA model, with corrections as necessary, R3 updated landfill capacity projections based on information through 2017.
R3 also developed an Excel-based tonnage scenario modeling tool for Zero Waste Marin that meets legislative and regulatory specifications and builds upon the updated disposal reporting workbook. The Excel tool allows Zero Waste Marin staff to “plug in” scenarios for alternative disposal and materials handling situations, allowing for consideration of various scenarios over time and better planning for future changes.
Finally, R3 prepared a draft and final report, and prepared and delivered presentations to Zero Waste Marin.
- Characterization of SB 1383 compliance related to a 50% reduction in organic waste disposal from the 2014 level by 2020, and a 75% reduction by 2025;
- Updates to Zero Waste Marin’s Excel workbook for CalRecycle State Disposal Reporting System (DRS) for reporting under AB 901, including new hauler and facility reporting needs and specification of information to obtain directly from the haulers and facilities for JPA assessment calculations; and
- A user-friendly Excel tool for Zero Waste Marin staff that enhances Marin County reporting capabilities and facilitate long-term solid waste planning.
