<br />2020 Solid Waste and Moderate <br />Risk Waste Management Plan Update <br /> <br />7-6 AX0304191054PDX <br />7.3.2 Agricultural Waste Needs and Opportunities <br />There are options for beneficial reuse of biomass within the County and investigating the feasibility of <br />developing a facility for the production of biofuels, biopower, or bioproducts. Biomass is any sort of <br />vegetation - trees; grasses; and plant parts such as leaves, stems, and twigs. During photosynthesis, <br />plants combine carbon dioxide from the air with water to form carbohydrates, which form the building <br />blocks of biomass. Biomass can produce electricity, heat, liquid fuels, gaseous fuels, and a variety of <br />useful chemicals, including those currently manufactured from fossil fuels. Currently, biomass can be <br />used for: <br /> Biofuels: Liquid fuels for transportation, such as ethanol and biodiesel. <br /> Biopower: The use of biomass feedstocks instead of conventional fossil fuels (natural gas or coal) to <br />generate electricity or industrial process heat and steam. Biomass is burned and the resultant heat is <br />used to turn water into steam, which is then used to turn turbines that are connected to electric <br />generators. <br /> Bioproduct: A chemical, material, or other product derived from renewable biomass resources. <br />7.3.3 Agricultural Waste Recommended Option and Implementation Action <br />The following options for improving agricultural waste management are recommended. Each option and <br />the associated implementation actions are discussed below. <br />7.3.3.1 Evaluate Opportunities for Beneficial Reuse of Biomass <br />Maintain biomass use as an option for study and consideration if future needs and conditions support its <br />use and monitor other projects within the state. <br />Review the feasibility of developing biomass facilities in the County, if under consideration. This review <br />would include appropriate technologies for further consideration, based on potential feedstock; <br />advantages and disadvantages of those technologies compared to landfilling; ability to maintain local <br />control over disposal; ability to locally produce renewable energy and green fuels; capital and operational <br />costs; by-product characteristics and uses; impacts on diversion goals; environmental considerations; <br />social considerations; permitting requirements; land ownership; cultural resources; and site selection. <br />7.3.4 Other Nuisances <br />The Public Health Department has the responsibility to enforce commercial and residential onsite solid <br />waste storage code (e.g., designated areas for garbage disposal 8.20.010 RCW; litter receptacles <br />70.93.090) and can share enforcement responsibilities to other agencies with police powers to enforce <br />littering rules (RCW 70.93.050) This multi-agency collaboration is necessary to reduce the occurrences of <br />rodents and health and safety nuisances. <br />7.4 Tires <br />The term “tires” refers to tires from automobiles, trucks, tractors, or any other use. They are formed from <br />rubber and usually reinforced with cords of nylon, fiberglass, or steel. Tires do not include the metal wheel <br />to which they are usually fastened. <br />Refuse tires are an inevitable by-product of normal vehicle use. A tire becomes refuse when it wears out <br />and is not retreaded or reused. With its useful life over, it must be stored (temporarily) or disposed of. Tire <br />dealerships remove most old tires in the process of selling new ones. Individuals may also accumulate <br />old tires. When vehicles are junked, the tires on the vehicle, spares, and snow tires may be stored by the <br />owner or the wrecking yard. <br />General statutory nuisance regulations and the Solid Waste Handling Standards (Chapter 173- 350 WAC) <br />provide standards for the regulation and storage of tires. The state requirements call for tires to be
