5 CCR 1002-93 - REGULATION NO. 93 - COLORADO'S SECTION 303(D) LIST OF IMPAIRED WATERS AND MONITORING AND EVALUATION LIST
Section 5 CCR 1002-93.3 - Waterbodies that are Impaired or Identified for Monitoring and Evaluation
Only those segments where a Clean Water Section 303(d) Impairment has been determined require TMDLs. For these segments, TMDLs are only required for those parameters that are identified as impairments.
The table below includes several key data elements that warrant description. They are: Waterbody ID and Listed Portion/Assessment Unit ID (AUID), Affected Use, Category/List, and Priority.
* Waterbody ID and Listed Portion/Assessment Unit ID (AUID): For each impairment listed in the table, both a Waterbody ID (WBID) and an Assessment Unit ID (AUID) description are provided. The WBID ID describes the entire segment and is derived from basin regulations 32-38. The AUID, which includes an underscore and letter, describes the spatial extent of the impairment listings within the waterbody ID. The AUID is referred to as the "Listed Portion." In situations when the listed portion description matches the segment description, the entire segment is listed.
* Affected Use: The Affected Use refers to a designated use that is applied to the water body segment.
* Category/List: These categories describe waterbody attainment status. These entries are aligned with Environmental Protection Agency reporting categories.
