This layer depicts the official TCEQ Poly Assessment Units (AU) for the State of Texasas listed in Title 30, Chapter 307 of the Texas Administrative Code (TAC), also known asthe Texas Surface Water Quality Standards. Assessment Units are sub-areas of segments,defined as the smallest geographic area of use support reported in the assessment.These are reservoirs, estuaries, oyster waters, beaches, and ocean that have been individuallydefined by the TCEQand assigned unique identification numbers. Intended to have relatively homogeneouschemical, physical, and hydrological characteristics, an AU provides a basic unit for assigningsite-specific standards and for applying water quality management programs of the agency.AU's from both "classified" and "unclassified" segments have been included in this layer.Classifiedsegments, also referred to as designated segments, refer to water bodies that areprotected by site- specific criteria. The classified segments are listed and described inAppendix A and C of Chapter 307.10. The site-specific uses and criteria are described inAppendix A. Classified waters include most rivers and their major tributaries, majorreservoirs, and estuaries. Unclassified waters are those smaller water bodies that do nothave site-specific water quality standards assigned to them, but instead are protected bygeneral standards that apply to all surface waters in the state.This layer also indentifies which AUs and water bodies have been assessed in the2014 Texas Integrated Report for Clean Water Act Sections 305 (b) and 303 (d).An impaired AU is included in Categories 4 and 5. Category 4 includesimpairments that are not suitable for a TMDL or for which a TMDL has already beenapproved. Category 5 includes impairments which may be suitable for development of a TMDLand comprise the 303 (d) List. Uploaded to SARA GIS Library on 2/15/2018 |
