The definitions in this section apply to this chapter unless
				the context requires otherwise.
(1)
			 "Average daily traffic" or "ADT" means the total traffic volume during a given
			 time period (in whole days) greater than one day and less than one year divided
			 by the number of days in that time period. ADT is determined by
			 WSDOT.
(2) "Best management
			 practices" or "BMPs" means physical, structural, and/or managerial practices
			 that when used singly or in combination prevent or reduce pollution of water
			 and have been approved by ecology. BMPs are listed and described in the manual
			 defined in subsection (9) of this section.
(3) "Broadcast application" means a uniform
			 application of pesticides to an entire area.
(4) "Buffer zone" means the minimum distance
			 that a pesticide is permitted to be applied from a physical feature or
			 sensitive area.
(5) "Capital
			 improvement program plan" means a schedule of permanent physical structural
			 improvements budgeted to fit financial resources.
(6) "Ecology" means the Washington state
			 department of ecology.
(7) "EPA"
			 means the U.S. Environmental Protection Agency.
(8) "Experimental BMP" means any treatment or
			 methodology proposed for treatment of highway runoff that is not in the highway
			 runoff manual, defined in subsection (9) of this section, and is being studied
			 by WSDOT and/or ecology for adoption as a BMP.
(9) "Highway runoff manual" means the manual
			 adopted by WSDOT and approved by ecology that contains BMPs to prevent or
			 reduce pollution, and described in WAC
			 173-270-030.
(10) "Integrated pest management" or "IPM"
			 means the selection, integration, and implementation of pest control that
			 consists of: Prevention of pest problems; monitoring and evaluation of pests,
			 damage and results of treatment; acknowledgment of population levels of pests
			 that can be tolerated based on legal, economic, health, or aesthetic
			 thresholds; use of natural control agents in an ecosystem; reliance to the
			 maximum extent possible on nonhazardous biological, mechanical, and cultural
			 treatment of pests; application of pesticides in a manner that minimizes damage
			 to the ecosystem's natural controls and integrity; and use of pesticides only
			 after all other methods have been evaluated.
(11) "Local government" means a county, city,
			 town, or special purpose district that has authority to manage
			 stormwater.
(12) "New construction"
			 means the addition of one or more lanes, ramps, bridges, or other major

			 highway.
(13) "Pest" means any form
			 of plant or animal life or virus (except virus on or in living man or other
			 animal) which is normally considered to be a pest or which the director of the
			 WSDA may declare by regulation to be a pest, including but not limited to, any
			 insect, other arthropod, fungus, rodent, nematode, mollusk, or weed.
(14) "Pest treatment" means mechanical,
			 biological, cultural, or chemical procedures or methods to manage, control, or
			 reduce the influence of a pest.
(15) "Pesticide" means as defined by chapter
			 17.21 RCW, the Washington Pesticide Act, and regulated by the United States
			 Environmental Protection Agency and WSDA.
(16) "Pollution" means such contamination or
			 other alteration of the physical, chemical, or biological properties of any
			 waters of the state, including change in temperature, taste, color, turbidity,
			 or odor of the waters, or such discharge of any liquid, gaseous, solid,
			 radioactive, or other substance into any waters of the state as will or is
			 likely to create a nuisance or render such waters harmful, detrimental, or
			 injurious to the public health, safety or welfare, or to domestic, commercial,
			 industrial, agricultural, recreational, or other legitimate beneficial use, or
			 to livestock, wild animals, birds, fish, or other aquatic life.
(17) "Puget Sound basin" means the waters of
			 Puget Sound south of Admiralty Inlet including Hood Canal and Saratoga Passage;
			 the waters north to the Canadian border, including portions of the Strait of
			 Georgia; the Strait of Juan de Fuca south of the Canadian border; and all land
			 draining into these waters as mapped in WAC
			 173-500-040 Water resource
			 inventory areas numbers 1 through 19.
(18) "Quality assurance and control plan"
			 means a collection of policies, objectives, principles, and procedures for
			 attaining data of known and accepted quality and establishes standards of
			 performance for sampling, monitoring, and measurement.
(19) "Sensitive area" means an area or that
			 due to its ground or surface water characteristics may be adversely affected or
			 altered directly or indirectly by pollution and requires special vegetation
			 management, stormwater management, or other practices.
(20) "Spot treatment" means the application
			 of pesticides to a selected individual area or species.
(21) "Stormwater management manual" means the
			 technical manual prepared by ecology for use by local governments and WSDOT
			 that contains BMPs to prevent or reduce pollution in stormwater.
(22) "Stormwater treatment" means chemical,
			 biological, or mechanical procedures or structural methods to remove, reduce,
			 or neutralize pollution.
(23)
			 "Waters of the state" means lakes, rivers, ponds streams, inland waters,
			 underground waters, salt waters, and all other surface waters and water courses
			 within the jurisdiction of the state of Washington.
(24) "Wetlands" means those areas that are

			 sufficient 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
