(A) The water bodies listed in table 30-1 of this rule are ordered from downstream to upstream. Tributaries of a water body are indented. The aquatic life habitat, water supply and recreation use designations are defined in rule 3745-1-07 of the Administrative Code. The state resource water use designation is defined in rule 3745-1-05 of the Administrative Code. The most stringent criteria associated with any one of the use designations assigned to a water body will apply to that water body.
(B) Figure 1 of the appendix to this rule is a generalized map of the Mill creek drainage basin. A generalized map of Ohio outlining the twenty-three major drainage basins and listing associated rule numbers in Chapter 3745-1 of the Administrative Code is in figure 1 of the appendix to rule 3745-1-08 of the Administrative Code.
(C) RM, as used in this rule, stands for river mile and refers to the method used by the Ohio environmental protection agency to identify locations along a water body. Mileage is defined as the lineal distance from the downstream terminus (i.e., mouth) and moving in an upstream direction.
(D) The following symbols are used throughout this rule:
* Designated use based on the 1978 water quality standards;
+ Designated use based on the results of a biological field assessment performed by the Ohio environmental protection agency;
o Designated use based on justification other than the results of a biological field assessment performed by the Ohio environmental protection agency; and
L An L in the warmwater habitat column signifies that the water body segment is designated limited warmwater habitat.
