Integrated Reporting Look-up Tables
In the Guidance for 2006 Assessment, Listing, and Reporting Requirements Pursuant to Sections 303(d), 305(b), and 314 of the Clean Water Act [2006 Integrated Report Guidance (IRG)], EPA provided information on the data elements that should be included in a States electronic data submission. EPA recommends that States use the Look-up Tables provided below when preparing their electronic data submission.
This information is made available to the public via the Assessment and Total Maximum Daily Load (TMDL) Tracking and Implementation System (ATTAINS)..
Designated Use Look-up Table |
In the electronic data submission, States are required to identify the designated uses that apply to each assessment unit, such as primary contact recreation, aquatic life support, and public water supply. |
Cause of Impairment Look-up Table |
In the electronic data submission when a designated use is not supporting, States are required to identify the pollutants causing water quality impairment. Causes of impairment include chemical contaminants (such as PCBs, metals, and oxygen-depleting substances), physical conditions (such as elevated temperature, excessive siltation, or habitat alterations), and biological contaminants (such as bacteria and noxious aquatic weeds). |
Probable Source Look-up Table |
In the electronic data submission, EPA recommends that States provide the probable sources for the pollutants causing water quality impairment. Probable sources include: municipal sewage treatment plants, factories, storm sewers, modification of hydrology, agricultural runoff, and runoff from city streets. |
Water Type Look-up Table |
In the electronic data submission, States are required to provide a description of the type of water the waterbody represents (e.g., river, stream, lake, estuary). |
Delisted Reason Look-up Table |
Causes of impairment associated with assessed waters may be removed from a State's 303(d) list for a number of reasons, which include: TMDL alternative, impairment due to pollution, new assessment methods, change in water quality standards, restoration activities, incorrect basis for original listing, and removal of the threatened status of a water. |
