(A)
								The chemical-specific criteria listed in this rule
			 apply as "Outside Mixing Zone" or "Inside Mixing Zone Maximum." For the purpose
			 of setting water quality based effluent limits, the criteria which apply
			 "Outside Mixing Zone" shall be met after the effluent and the receiving water
			 are reasonably well mixed as provided in rules
			 3745-1-06
			 and
			 3745-2-05
			 of the Administrative Code. The criteria listed as "Inside Mixing Zone Maximum"
			 shall be applicable as end-of-pipe maximum effluent limits or as criteria to be
			 met within a short distance of the effluent pipe except as provided in rule
			 3745-2-08
			 of the Administrative Code. Possible exceptions regarding the application of
			 these criteria may apply as described in paragraph (C) of rule
			 3745-1-07
			 of the Administrative Code.
(B)
								The water quality
			 criteria adopted in, or developed pursuant to, this rule shall apply as
			 follows:
(1)
									The "Inside Mixing Zone Maximum" and "Outside Mixing Zone
			 Maximum" water quality criteria for the protection of aquatic life, or
			 site-specific modifications thereof, shall apply to all water bodies. Water
			 quality criteria applicable to specific aquatic life use designations are
			 listed where appropriate. The "Inside Mixing Zone Maximum" and "Outside Mixing
			 Zone Maximum" water quality criteria identified for the warmwater habitat use
			 designation apply to water bodies not assigned an aquatic life use
			 designation.
(2)
									The "Outside Mixing Zone Average" water quality
			 criteria for the protection of aquatic life, or site-specific modifications
			 thereof, shall apply to all water bodies except those water bodies assigned the
			 limited resource water use designation. However, the limited resource water
			 "Outside Mixing Zone Average" water quality criteria for dissolved oxygen, pH
			 and temperature apply to water bodies assigned the limited resource water use
			 designation.
Water quality criteria applicable to
				specific aquatic life use designations are listed where appropriate. The
				"Outside Mixing Zone Average" water quality criteria identified for the
				warmwater habitat use designation apply to water bodies not assigned an aquatic
				life use designation.
(3)
									Criteria for protection of wildlife, or site-specific
			 modifications thereof, are "Outside Mixing Zone Average" water quality criteria
			 and shall apply to all water bodies located in the lake Erie drainage
			 basin.
