Section 90.46.010. Definitions.

The definitions in this section apply throughout this chapter unless the context clearly requires otherwise.

(1) "Agricultural industrial process water" means water that has been used for the purpose of agricultural processing and has been adequately and reliably treated, so that as a result of that treatment, it is suitable for other agricultural water use.

(2) "Agricultural processing" means the processing of crops or milk to produce a product primarily for wholesale or retail sale for human or animal consumption, including but not limited to potato, fruit, vegetable, and grain processing.

(3) "Agricultural water use" means the use of water for irrigation and other uses related to the production of agricultural products. These uses include, but are not limited to, construction, operation, and maintenance of agricultural facilities and livestock operations at farms, ranches, dairies, and nurseries. Examples of these uses include, but are not limited to, dust control, temperature control, and fire control.

(4) "Constructed beneficial use wetlands" means those wetlands intentionally constructed on nonwetland sites to produce or create natural wetland functions and values.

(5) "Constructed treatment wetlands" means wetland-like impoundments intentionally constructed on nonwetland sites and managed for the primary purpose of further treatment or retention of reclaimed water as distinct from creating natural wetland functions and values.

(6) "Direct groundwater recharge" means the controlled subsurface addition of water directly into groundwater for the purpose of replenishing groundwater.

(7) "Domestic wastewater" means wastewater from greywater, toilet, or urinal sources.

(8) "Greywater or gray water" means domestic type flows from bathtubs, showers, bathroom sinks, washing machines, dishwashers, and kitchen or utility sinks. Gray water does not include flow from a toilet or urinal.

(9) "Industrial reuse water" means water that has been used for the purpose of industrial processing and has been adequately and reliably treated so that, as a result of that treatment, it is suitable for other uses.

(10) "Land application" means use of reclaimed water as permitted under this chapter for the purpose of irrigation or watering of landscape vegetation.

(11) "Lead agency" means either the department of health or the department of ecology that has been designated by rule as the agency that will coordinate, review, issue, and enforce a reclaimed water permit issued under this chapter.

(12) "Nonlead agency" means either the department of health or the department of ecology, whichever is not the lead agency for purposes of this chapter.

(13) "Person" means any state, individual, public or private corporation, political subdivision, governmental subdivision, governmental agency, municipality, copartnership, association, firm, trust estate, or any other legal entity whatever.

(14) "Planned groundwater recharge project" means any reclaimed water project designed for the purpose of recharging groundwater.

(15) "Reclaimed water" means water derived in any part from wastewater with a domestic wastewater component that has been adequately and reliably treated, so that it can be used for beneficial purposes. Reclaimed water is not considered a wastewater.

(16) "State drinking water contaminant criteria" means the contaminant criteria found in the drinking water quality standards adopted by the state board of health pursuant to chapter 43.20 RCW and the department of health pursuant to chapter 70.119A RCW.

(17) "Streamflow or surface water augmentation" means the intentional use of reclaimed water for rivers and streams of the state or other surface water bodies, for the purpose of increasing volumes.

(18) "Surface percolation" means the controlled application of water to the ground surface or to unsaturated soil for the purpose of replenishing groundwater.

(19) "User" means any person who uses reclaimed water.

(20) "Wastewater" means water-carried wastes from residences, buildings, industrial and commercial establishments, or other places, together with such groundwater infiltration and inflow as may be present.

(21) "Wetland or wetlands" means areas that are inundated or saturated by surface water or groundwater at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted to life in saturated soil conditions. Wetlands generally include swamps, marshes, bogs, and similar areas. Wetlands regulated under this chapter shall be delineated in accordance with the manual adopted by the department of ecology pursuant to RCW 90.58.380.
