Within the Chehalis Basin Action Plan, the following definitions and acronyms shall apply:
"Aquaculture" is the controlled cultivation and harvest of aquatic plants or animals (e.g., edible marine algae, clams, oysters, and salmon).
"Best Management Practices" (BMPs) means agricultural, structural, and/or managerial practices that, when used singly or in combination, provide minimum essential action or treatment needed to solve, prevent, or reduce site-specific water quality problems. BMPs may be part of an approved site development plan or farm plan.
"Biosolids", commonly referred to as sludge, is the semisolid, stabilized digested residual material derived from municipal waste water treatment plants. To be defined as biosolids, this material must meet all state and federal standards for beneficial application to agricultural lands.
"Cooperative Monitoring, Evaluation and Research (CMER) Committee" is a Timber/Fish/Wildlife committee established to identify, design and oversee needed forest watershed studies which may indicate the need for changes in forest practices rules and regulations. In addition, the CMER committee has established a number of technical steering committees to work in specific scientific fields.
"Conservation plan" , also referred to as "farm plan" means a site-specific plan developed by a farm operator in cooperation with a resource agency (such as those developed under the "208" water quality management program with assistance of a conservation district or the soil conservation service) and approved by the conservation district board of supervisors, for managing resources to protect water quality.
"Cubic feet per second (cfs)" is the common unit of measurement for stream flow.
"Farm" means a property where domesticated animals are kept to provide primary or supplemental income, for personal consumption, or for recreational use, or where crops are grown for resale.
"Forest roads (active vs. inactive)" - An "active" road is a forest road being actively used for hauling of logs, pulpwood, chips, or other major forest products or rock and other road building materials. An "inactive" road is a forest road or old railroad grade on which commercial hauling is discontinued for one or more logging seasons, and the forest landowner desires continuation of access for control, forest management activities, Christmas tree growing operations, occasional or incidental use for minor forest products harvesting or similar activities.
"Hazardous waste" is any solid, liquid, or gaseous substance which, because of its source or measurable characteristics, is classified under state or federal law as hazardous and is subject to special handling, shipping, storage, and disposal requirements. Washington state law identifies two categories, dangerous and extremely hazardous. Neither is authorized for direct discharge into ground or surface waters.
"Integrated Pest Management (IPM)" is the selection, integration, and implementation of pest control based on predicted economic, ecological, and sociological consequences. IPM seeks maximum use of naturally occurring pest controls, including weather, disease agents, predators, and parasites. In addition, IPM utilizes various biological, physical, and chemical control and habitat modification techniques. Artificial controls are imposed only as required to keep a pest from surpassing intolerable population levels predetermined from accurate assessments of the pest damage potential and the ecological, sociological, and economic costs of the control measures.
"Leachate" is water or other liquid that has washed (leached) from or through a solid material, such as a layer of soil or debris. Leachate may contain contaminants such as organics or mineral salts. Rainwater that percolates through a sanitary landfill and picks up contaminants is leachate from the landfill when it is collected or removed.
"Nonpoint Source Pollution (NPS)" enters water from dispersed and uncontrolled sources (such as surface runoff). Nonpoint sources (e.g., forest practices, agricultural practices, storm water, on-site sewage disposal, and recreational boats) may contribute pathogens, suspended solids, and toxicants. While individual sources may seem insignificant, the cumulative effects of nonpoint source pollution can be significant.
"On-site sewage disposal system" means a septic tank and drainfield or alternative treatment and disposal system.
"Public resources" means water, fish, and wildlife and in addition shall mean capital improvements funded by the state or its political subdivisions.
"Right-to-farm ordinances" discourage nuisance claims against common agricultural practices by promoting and protecting agriculture, farm forestry and dependent rural communities through the enhancement, protection, and perpetuation of the agricultural private sector to produce food and fiber.
"Riparian area" is a vegetated ecosystem along a waterbody through which energy, materials, and water pass. Riparian areas characteristically have a high water able and are subject to periodic flooding and influence from the adjacent waterbody.
"River Mile (RM)" is the distance upstream from the mouth or entry point of a stream.
"Septage" is a semiliquid substance consisting of settled sewage solids and dissolved materials combined with varying amounts of water. Septage is generated from a private waste water treatment system, such as a septic tank.
"Silage" is livestock feed that has been subjected to anaerobic fermentation.
Soil Conservation Service (SCS)
"Source control" is a practice, method, or technology that is used to reduce pollution from a source; for example, best management practices or end-of-pipe treatment.
"Storm water" is water generated by rainfall and is often routed into drain systems in order to prevent flooding.
"Timber/Fish/Wildlife Agreement (TFW)" is an agreement between the timber industry, state resource agencies, the tribes and environmental groups that promotes the monitoring and protection of fish, wildlife, water and public resources as an integral component of forestry management practices.
"Total Maximum Daily Load (TMDL)" is the amount of a pollutant a waterway can assimilate without harming beneficial uses. Once a TMDL is determined, it is divided among the existing point and nonpoint sources, with a portion reserved for scientific uncertainty and future growth.

"Watershed Initiative (Forest Service)" is a cooperative watershed rehabilitation program on National Forest land designed to identify specific sites and, in some areas, entire watersheds, that are in need of special planning and treatment in order to protect and restore water quality, site productivity, fish and wildlife habitat, roads, and various other investments.
"Wetlands" as defined in Washington Forest Practices Rules and Regulations, September 1992, are those areas that are inundated or saturated by surface or ground water at a frequency and duration to support, and that 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.
