Ohio Administrative Code › Title 3745 - Ohio Environmental Protection Agency › Chapter 3745-1 - Water Quality Standards › Section 3745-1-25 - Mahoning river drainage basin

Current through all regulations passed and filed
			 through July 1, 2024
(A)
			 The water bodies listed in table 25-1 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 Mahoning river drainage basin. A generalized map of
			 Ohio outlining the twenty-three major drainage basins and listing associated
			 rule numbers in this chapter 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.

				river drainage basin.
