AB 939 or Assembly Bill 939 - AB 939 enacted the California Integrated Solid Waste Management Act of 1989, which governs solid waste management, source reduction, recycling, composting, and market development within the state of California. Active Compost - Compost feedstock that is in the process of being rapidly decomposed and is unstable. Active compost is generating temperatures of at least 50 degrees Celsius during decomposition; and is releasing carbon dioxide at a rate of at least 15 milligrams per gram of compost per day, or the equivalent of oxygen uptake. Additives - Material mixed with feedstock or active compost in order to adjust the moisture level, carbon to nitrogen ratio, or porosity to create a favorable condition. Additives include, but are not limited to, fertilizers and urea. Additives do not include septage, sewage, or compost feedstock. Aerated Static Pile - The method of composting that involves mechanically moving air through the compost pile, either through suction or blowing air through the pile. Alternative Daily Cover (ADC) - Cover material other than at least six inches of earthen material, placed over solid waste at the end of each operating day to control vectors, fires, odors, blowing litter, and scavenging. Amendments - Materials added to stabilized or cured compost to provide attributes for certain compost products, such as product bulk, product nutrient value, product pH, and soils blend. Amendments do not include septage, sewage, or compost feedstock.
Biomass Fuel - Ground green material used for Biomass Conversion. (See Biomass Conversion.) Biomass Conversion - The controlled combustion, when separated from other solid waste and used for producing electricity or heat, of the following materials: 1. Agricultural crop residues. 2. Bark, lawn, yard and garden clippings. 3. Leaves, silvicultural residue, and tree and brush pruning. 4. Wood, wood chips and wood waste. 5. Nonrecyclable pulp or nonrecyclable paper materials "Biomass conversion" does not include the controlled combustion of recyclable pulp or recyclable paper materials, or materials that contain sewage sludge, industrial sludge, medical waste, hazardous waste, or either high-level or low-level radioactive waste.
California Environmental Quality Act (CEQA) - A Public Resources Code section 21000 et seq. that was enacted in 1970 as a system of checks and balances for land use development and management decisions in California. CEQA is California's most significant environmental law. It requires state, local and other agencies subject to the jurisdiction of California to evaluate the environmental implications of their actions. It aims to minimize environmental effects of the agency actions by requiring agencies to avoid or reduce, when feasible, the significant impacts of their decisions. Chipping and Grinding - An activity that mechanically reduces the size of organic matter. Compost - The product resulting from the controlled biological decomposition of organic wastes that are source-separated from the municipal solid waste stream, or which are separated at a centralized facility. Compost includes vegetable, yard, and wood wastes, which are not hazardous waste. Composting Facility - A facility that is operated for the purpose of producing compost. A "Composting Facility" includes: 1. Green material composting facilities that have greater than 1,000 cubic yards of feedstock and active compost on site at any one time. 2. Animal material composting facilities. 3. Sewage sludge composting facilities. 4. Mixed solid waste composting facilities
Garden Refuse - Residential plant material that is source-separated at the point of generation. Garden refuse includes, but is not limited to, yard trimmings. Garden refuse does not include treated wood waste, mixed demolition, or mixed construction debris. Other names for garden refuse include "green waste" and "green material". Garden Refuse-Derived Products - Commodities derived from processed garden refuse and may include finished compost, mulch, biomass fuel, and alternative daily cover (ADC) for landfills. Green Material - See Garden Refuse. Green Waste - See Garden Refuse.
In-Vessel - The method of composting where the composted materials are completely encapsulated during the composting process.
Landfill - A waste management unit at which waste is discharged in or on land for disposal. It does not include surface impoundment, waste pile, land treatment unit, injection well, or soil amendments.
Mulch - Material produced through chipping and grinding of green material.
Preliminary Siting Criteria - Factors to be taken into account when assessing the suitability of a potential site. Project Advisory Committe (PAC) - The PAC
membership consists of community leaders and representatives from stakeholder
groups that have a specific interest in the Sacramento GreenCycle facility
siting process. The PAC considers a full range of facility siting issues,
and makes recommendations about community outreach and involvement efforts. Public-Private Partnership - An agreement for services whereby public and private sectors collaborate in a partnership to provide services by contract.
Sacramento GreenCycle Project
Team - The Sacramento GreenCycle Project Team is lead by
Sacramento
Regional Solid Waste Authority (SWA) staff, and is assisted by CH2M
Hill (a technical consulting firm) and MMC
Communications (a public relations consulting firm). Soil Amendment - Material added to soil to change its properties, including but not limited to compost, mulch, pearlite, wood chips or shavings, nutrients, coloring, etc. Stakeholder - An individual or entity with
an interest in a project, including but not limited to permitting agencies,
affected neighbors, public groups, environmental reviewers, etc.
Transfer Station - A facility used for the unloading, consolidation and transfer of waste materials.
Unaerated Static Pile - The method of composting that does not involve turning the pile or the use of mechanical devices for the purpose of introducing oxygen into the pile.
Windrow - A long open-air pile of garden refuse. Windrow Composting - The method of composting
that involves physical disturbance of the pile at regular intervals
in order to introduce oxygen and water to the pile.
