Category Definitions 

1 = Attaining all designated uses;
2 = Attaining some designated uses, but there is insufficient data to determine if other uses are being attained;
3 = Insufficient data to determine if any designated use(s) is attained;
4 = Impaired for one or more designated uses, but does not require the development of a TMDL because:
a. A TMDL has been completed for the listed parameter(s);
b. Other pollution control requirements are expected to result in attainment of water quality standards;
c. Waters which are not attaining current water quality standards and/or assessment criteria but do not  require the development of a TMDL because the impairment is not caused by a pollutant.
5 = The waterbody may be impaired, or one or more designated uses may not be attained. Waterbodies in Category 5 are placed in one of the following subcategories by the Arkansas Department of Environmental Quality for management  purposes:
a. Truly impaired; develop a TMDL or other corrective action(s) for the listed parameter(s);
b. Waters not attaining standards, but could be de-listed with the adoption of future Regulation No. 2 revisions;
c. Waters in which the data is questionable because of QA/QC procedures and which require confirmation before a TMDL or other corrective action(s) is scheduled;
d. Waters which need data verification to confirm use impairment (additional sampling, biological assessment) before a TMDL or other corrective action(s) is scheduled;
e. Waters which are impaired by point source discharges and future permit restrictions are expected to correct the problem;
f. These are waters that are not currently meeting a water quality standard. However, “the basis for not meeting an applicable water quality standard is not caused by a pollutant, but is attributed to other types of pollution” (EPA, 2005).
