Specific water quality criteria are dependent upon the particular waterbody an dits associated use classification.* ii For streams, lakes and reservoirs in the Tennessee and Cahaba River Basins, and for specific segment of the Tallapossa River Basin, that has been designated b ythe Alabama Department of Conservation and Natural Resources as supporting smallmouth bass, saugher, or walleye, the instream temperature shall not exceed 86F.* iii The maximum instream temperature rise above ambient water temperature due to the addition of artificial heat by a discharger shall not exceed 4 F in coasta lestuarine waters during the period October through May, nor shall the rise exceed 1.5 F during the period June through September.* iv For incidental water contact and recreation during June through September, the bacterial quality of the water is acceptable when sanitary survey by th econtrolling health authority reveals no source of dangerous pollution and when the geometric mean fecal coliform organism density does not exceed 100 col/100 ml(coastal waters) and 200 col/100 ml (other waters).* v Not to exceed the limits specified in the latest edition of the National Shellfish Sanitation Program Manual of Operations, Sanitation of Shellfish Growing Area s(1965), published by the Food and Drug Administration, U.S. Department of Health and Human Services.64
