ER -- ecoregion value
*  developed using background flow of 4 cfs
**  These criteria shall apply to all tributaries of Bayou Meto and Bayou Two Prairie listed in Appendix A Any modification of these values must be made in accordance with Rule 2.306.
†  Not applicable for Clean Water Act purposes until approved by EPA.
***  These temporary standards variations are effective for 148 months from EPA's approval of the EIP on January 7, 2020.
(B) Ecoregion Reference Stream Minerals Values
The following values were determined from Arkansas's least-disturbed ecoregion reference streams and are considered to be the maximum naturally occurring levels. For waterbodies not listed above, any discharge that results in instream concentrations more than 1/3 higher than these values for chlorides (Cl-) and sulfates (SO42-) or more than 15 mg/L, whichever is greater, is considered to be a significant modification of the maximum naturally occurring values. These waterbodies should be considered as candidates for site specific criteria development in accordance with Rules 2.306 and 2.308. Similarly, site specific criteria development should be considered if the following TDS values are exceeded after being increased by the sum of the increases to Cl- and SO42-. Such criteria may be developed only in accordance with Rules 2.306 and 2.308. The values listed in the table below are not intended to be used by the Division to evaluate attainment of water quality standards for assessment purposes.

(C) Domestic Water Supply Criteria
In no case shall discharges cause concentrations in any waterbody to exceed 250, 250, and 500 mg/L of chlorides, sulfates, and total dissolved solids, respectively, or cause concentrations to exceed the applicable criteria, except in accordance with Rules 2.306 and 2.308.
