"Soil" means material overlying bedrock consisting primarily of clay, silt, sand, or gravel size particles, and soil biota, that may contain de minimis amounts of other solid materials, such as incidental pieces of concrete or wood. Soil does not include dredged material. Cured concrete and asphalt are not soil.
"Soil amendment" means any substance that is intended to improve the physical characteristics of soil, except composted material, commercial fertilizers, agricultural liming agents, unmanipulated animal manures, unma-nipulated vegetable manures, food wastes, food processing wastes, and materials exempted by rule of the department, such as biosolids as defined in chapter 70.95J RCW, Municipal sewage sludge-Biosolids, and wastewater, as regulated in chapter 90.48 RCW, Water pollution control.
"Solid waste," "waste materials," or "wastes" means all putrescible and nonputrescible solid and semisolid wastes including, but not limited to, garbage, rubbish, ashes, industrial wastes, swill, sewage sludge, demolition and construction wastes, abandoned vehicles or parts thereof, contaminated soils and contaminated dredged material, and recyclable materials. See WAC 173-350-021 to determine if a material is solid waste.
"Solid waste handling" means the management, storage, collection, transportation, treatment, use, processing or final disposal of solid wastes, including the recovery and recycling of materials from solid wastes, the recovery of energy resources from wastes or the conversion of the energy in wastes to more useful forms or combinations thereof.
"Solid waste handling unit" means discrete areas of land, sealed surfaces, liner systems, excavations, facility structures, or other appurtenances within a facility used for solid waste handling.
"Source separation" means the separation of different kinds of solid waste at the place where the waste originates.
"Specified risk material" means the skull, brain, tri-geminal ganglia (nerves attached to brain and close to the skull exterior), eyes, spinal cord, distal ileum (a part of the small intestine), and the dorsal root ganglia (nerves attached to the spinal cord and close to the vertebral column) of cattle aged thirty months or older.
"Storage" means the holding of solid waste materials for a temporary period.
"Street waste" means solid or dewatered materials collected from stormwater catch basins and similar stormwater treatment and conveyance structures, and materials collected during street and parking lot sweeping.
"Surface impoundment" means a facility or part of a facility designed to contain an accumulation of liquids or sludges, and whose structural support is provided primarily by earthen materials. The term includes holding, storage, settling, and aeration pits, ponds, or lagoons, but does not include injection wells or infiltration basins.
"Surface water" means all lakes, rivers, ponds, wetlands, streams, inland waters, salt waters and all other surface water and surface water courses within the jurisdiction of the state of Washington.
"Tank" means a facility or part of a facility designed to contain an accumulation of liquids or sludges, and designed and constructed of materials with sufficient strength so that its walls can be self-supporting.
"Tip floor" or "tipping floor" means the receiving area for incoming waste at a transfer station, material recovery facility, or recycling facility where vehicles unload waste materials prior to processing or consolidation for transport. A container into which waste is directly deposited, such as a drop box, is not a tipping floor.
"Transfer station" means a facility that receives solid waste (e.g., municipal solid waste, contaminated soil, or other solid wastes) from off-site from persons or route collection vehicles for consolidation into transfer vehicles, vessels, or containers for transport to a solid waste handling facility.
"Treatment" means the physical, chemical, or biological processing of solid waste to make solid wastes safer for storage or disposal, amenable for recycling or energy recovery, or reduced in volume.
"Twenty-five-year storm" means a storm of twenty-four hours duration and of such an intensity that it has a four percent probability of being equaled or exceeded each year.
"Universal wastes" means universal wastes as defined in chapter 173-303 WAC, Dangerous waste regulations. Universal wastes include, but may not be limited to, dangerous waste batteries, mercury-containing thermostats, and universal waste lamps generated by fully regulated dangerous waste generators or CESQGs.
"Unstable area" means a location that is susceptible to forces capable of impairing the integrity of the facility's liners, monitoring system or structural components. Unstable areas can include poor foundation conditions and areas susceptible to mass movements.
"Vadose zone" means that portion of a geologic formation in which soil pores contain some water, the pressure of that water is less than atmospheric pressure, and the formation occurs above the zone of saturation.
"Vector" means a living animal including, but not limited to, insects, rodents, and birds, which is capable of transmitting an infectious disease from one organism to another.
"Vermicomposting" means the controlled and managed process by which live worms convert organic residues into dark, fertile, granular excrement.
"Waste tires" means any tires that are no longer suitable for their original intended purpose because of wear, damage or defect. Waste tires include tires originally intended for use on public highways that are considered unsafe for this use in accordance with RCW 46.37.425. Waste tires also include quantities of used tires that may be suitable for their original intended purpose when mixed with tires not suitable for their original intended purpose.
"Wetlands" means those areas that are inundated or saturated by surface or groundwater at a frequency and duration sufficient to support, and under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally include swamps, marshes, bogs, and similar areas.
"Wood derived fuel" means wood pieces or particles used as a fuel for energy recovery, which contain paint, bonding agents, or creosote. Wood derived fuel does not include wood pieces or particles coated with paint that contains lead or mercury, or wood treated with other chemical preservatives such as pentachlorophenol, copper naphthenate, or cop-per-chrome-arsenate.
"Wood waste" means wood pieces or particles determined to be solid waste per WAC 173-350-021 generated from construction, demolition, handling and storage of raw materials, trees, stumps, and manufacturing of wood products. This may include, but is not limited to, sawdust, chips, shavings, bark, pulp, and log sort yard waste, but does not include wood pieces or particles containing paint, laminates, bonding agents, or chemical preservatives such as creosote, pentachlorophenol, or copper-chrome-arsenate.
"Yard debris" means plant material commonly created in the course of maintaining yards and gardens and through horticulture, gardening, landscaping or similar activities. Yard debris includes, but is not limited to, grass clippings, leaves, branches, brush, weeds, flowers, roots, windfall fruit, and vegetable garden debris.
"Zone of saturation" means that part of a geologic formation in which soil pores are filled with water and the pressure of that water is equal to or greater than atmospheric pressure.
