(51) Waste site is an area where material from a construction site is disposed. When 
the material is erodible, such as soil, the site must be treated as a construction site. 
(52) Waters (or waters of the state) means any and all water, public or private, on or 
beneath the surface of the ground, which are contained within, flow through, or border 
upon Tennessee or any portion thereof, except those bodies of water confined to and 
retained within the limits of private property in single ownership which do not combine 
or effect a junction with natural surface or underground waters. 
(53) Wat
 ers with unavailable parameters means any segment of surface waters that has 
been identified by the TDEC as failing to support one or more classified uses. 
Unavailable parameters exist where water quality is at, or fails to meet, the levels 
specified in water quality criteria in Rule 0400-40-03-.03, even if caused by natural 
conditions. In the case of a criterion that is a single response variable or is derived from 
measurement of multiple response variables, the unavailable parameters shall be the 
agents causing water quality to be at or failing to meet the levels specified in criteria. 
Resources to be used in making this determination include biennial compilations of 
impaired waters, databases of assessment information, updated GIS coverages 
(https://tdeconline.tn.gov/dwr/), and the results of recent field surveys. GIS coverages of 
the streams and lakes not meeting water quality standards, plus the biennial list of waters 
with unavailable parameters, can be found at https://www.tn.gov/environment/program-
areas/wr-water-resources/water-quality/water-quality-reports---publications.html.  
(54) Water quality riparian buffer means a permanent strip of natural perennial 
vegetation adjacent to a stream, river, wetland, pond, or lake that contains dense 
vegetation made up of grass, shrubs, and/or trees. The purpose of a water quality riparian 
buffer is to maintain existing water quality by minimizing the risk of any potential 
sediments, nutrients, or other pollutants reaching adjacent surface waters and to further 
prevent negative water quality impacts by providing canopy over adjacent waters. 
(55) A one-week period is a synonym of a calendar-week; typically, a period from 
Sunday through Saturday 
(56) Water quality treatment volume (WQTV) is a portion of the runoff generated from 
impervious surfaces at a new development or redevelopment project by the 1-year 24-
hour design storm. The WQTV is further determined by the type of treatment provided. 
(57) Wet weather conveyances are man-made or natural watercourses, including 
natural watercourses that have been modified by channelization, that meet the following: 
(a) The conveyance carries flow only in direct response to precipitation runoff in its 
immediate locality. 
(b) The conveyance’s channels are at all times above the groundwater table. 
(c) The flow carried by the conveyance is not suitable for drinking water supplies.
