+ 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.
L An L in the warmwater habitat column signifies that the stream segment is designated limited warmwater habitat.
Modeling projections of water quality in the channel have shown that levels of oxygen demanding materials found in natural waters are sufficient to depress dissolved oxygen below the warmwater habitat criteria. The modeling simulations also indicate that the existing loads of oxygen demanding materials could maintain the warmwater habitat dissolved oxygen criteria if the river depth was decreased to twelve feet. However, this would preclude the use of the channel for commercial navigation.
The physical habitat of the channel and the prevailing background dissolved oxygen regime are insufficient to support any resemblance of the warmwater habitat aquatic life use designation. A use attainability analysis has been conducted and indicates the extant fauna is substantially degraded and the potential for recovery of the fauna to the level characteristic of other lake Erie river mouths is precluded by irretrievable human induced conditions. However, the ship channel is used by fish as a migratory route in the spring months. This seasonal and stream flow related use shall be recognized and protected through this rule.
Full body contact recreational uses such as rowing, sculling and jet skiing do occur in the ship channel. The ship channel is also used as an industrial water supply but has no potential to support agricultural or public water supply uses.

e BOD5 values.
f A variance to these load limits is allowable unless the pending 301(g) variance request is denied. If the 301(g) variance request is denied, the established implementation schedule will apply.
g Loads calculated based upon design flow of 175 million gallons per day and are applicable to normal dry weather operation. Load values are not intended to restrict facility operation during wet weather flows when efforts are made to capture and treat combined sewer overflows.
