Explanation of Water Body Code Number. The water body subsegment number and unique water body identification code are designated as follows: AABBCC where: AA = Water Quality Management Basin Number BB = Segment Number CC = Subsegment Number Example: 090207 = Water Body Subsegment and Identification Code for Middle Pearl River and West Middle Pearl River where: 09 = Pearl River Management Basin 0902 = Segment 0902 of the Pearl River Management Basin 090207= Subsegment 090207 of Pearl River Management Basin Segment 02 C. Numeric Criteria Unit Definitions 1. Parameter Abbreviations. The following abbreviations of water quality parameters are used in Table 3 under the subheading "Numeric Criteria." Abbreviation | Parameter CL | Chlorides in mg/L SO4 | Sulfates in mg/L DO | Dissolved Oxygen in mg/L pH | Range of pH Units BAC | Bacterial Criteria (See Below) °C | Temperature in Degrees Centigrade (°C) TDS | Total Dissolved Solids in mg/L N/A | Not Available at Present 2. Bacterial Criteria (BAC) a. The code numbers associated with the following designated uses are used in Table 3 under the Numeric Criteria subheading “BAC.” Code | Designated Use 1 | Primary Contact Recreation 2 | Secondary Contact Recreation 3 | Drinking Water Supply 4 | Oyster Propagation b. The code number identified under the Numeric Criteria subheading "BAC" in Table 3 represents the most stringent bacterial criteria that apply to each individual subsegment. Where applicable, additional bacterial criteria also apply, depending on the designated uses of the subsegment and the geographic location of the subsegment. The specified numeric bacterial criteria for each designated use listed in this Paragraph can be found in LAC 33:IX.1113.C. D. Designated Uses.
