B. 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:

XXX = A minimum of three digits Unique Water Body Identification Code (If a Unique Water Body Identification Code is not identified for a particular Subsegment, then all water bodies within that Subsegment have the same designated uses and numerical criteria.)

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

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. The following notations for water use designations are used in Table 3 under the subheading "Designated Uses."

Notation	Designated Use
A	Primary Contact Recreation
B	Secondary Contact Recreation
C	Fish and Wildlife Propagation
L	Limited Aquatic Life and Wildlife Use
D	Drinking Water Supply
E	Oyster Propagation
F	Agriculture
G	Outstanding Natural Resource Waters
