� • Page 44 of 46 Srormtivater means that poRion of precipitation that does not naturally percolate into the ground or evaporate, but flows via overland flow, interflow, pipes, and other features of a stormwater drainage system into a defined surface water body, or a constructed infiltration faciliry. Smrmwnter Mana�ement Mmiva! (S�i',NM) or Manua( means the technical manual published by Ecology for use by local govemments that contain descriptions of and design criteria for BMPs to prevent, control, or treat pollutants in stormwater. Srormx�uter Pollution Preventior� Plan (Sfi'PPP) means a documented plan to implement measures to identify, prevent, and control the contamination of point source discharges of stormwater. Sur(ace Waters ofthe Smte includes lakes, rivers, ponds, streams, inland waters, salt waters, and all other surface waters and water courses within the jurisdiction of the state of Washington. Total Marimum Dailt� Load I"1'iti(DL) mcans a calculation of the maximum amount of a poUutant that a waterbody can receive and still meet state water quality standards. Percentages �f the total maximum daily load arc allocated to the various pollutant sources. A TMDL is the sum of the allowable loads of a single pollutant from all contributing point and nonpoint sources. The TMDL calculations shall include a"margin of safety" to ensure that the waterbody can be protected in case there arc unforeseen events or unknown sources of the pollutant. The calculation shall also account for scasonable variation in water quality. Treatmenr BMPs means BMPs that are intended to remove pollutanu from stormwater. A few examples of trcatment BMPs are detention ponds, oil/watcr separators, biofiltration, and constructcd wetlands. Trarrsnorencr means a measurement of �vater clarity in centimeters (cm), using a 60 cm. transparency tube. The transparency tube is used to estimate the relative dariry or transparency of water by noting the depth at which a black and white Secchi disc becomes visible when water is released from a valuc in thc bonom of thc tube. A transparency tube is sometimes referred to as a "turbidity mbc". Turbidrh� The clariry of watcr e�presscd as nephclometric turbidiry units (NTU) and measured with a calibrated turbidimetcr. [f�aste Lnod Allncntion (Ii'L;1) mcans thc portion of a rcceiving watcr's loading capaciry that is allocatcd to one of its existing or fumre point sources of pollution. WLAs constitute a type of ��ater qualiry based ef(luent limitation (40 CFR 130?(h)). Ii'ater Oira(im means the chemical, physical, and biological characteristics ofwater, usually with respect to iu suitability for a particular purpose. I('afcrs o(d�e Sta�e includes those waters as defined as "waters of the United States" in 40 CFR SuUpart 1?3.2 ��ithin the geoeraphic boundaries of Washington State and "waters of the state" as
