[Comment: For dates of non-regulatory government publications, publications of recognized organizations and associations, federal rules and federal statutory provisions referenced in this rule, see rule 3745-1-03 of the Administrative Code.]

(A) The Ohio river is designated warmwater habitat, public water supply, agricultural water supply, industrial water supply and bathing waters, and will meet the most stringent criteria set forth in, or derived in accordance with, this rule, rules 3745-1-01 to 3745-1-07 and 3745-1-33 to 3745-1-40 of the Administrative Code.

2mg/l = milligrams per liter (parts per million); µg/l = micrograms per liter (parts per billion); °F = degrees Fahrenheit.

3IMZM = inside mixing zone maximum; OMZM = outside mixing zone maximum; OMZA = outside mixing zone average.

4For dissolved oxygen, OMZM means outside mixing zone minimum at any time and OMZA means outside mixing zone minimum daily average.

aFor the months of May to October, the maximum allowable level of fecal coliform bacteria shall not exceed two hundred per one hundred ml as a monthly geometric mean based on not less than five samples per month; nor exceed four hundred per one hundred ml in more than ten per cent of all samples taken during the month. For the months of May to October, measurements of Escherichia coli bacteria may be substituted for fecal coliform. Content shall not exceed one hundred thirty per one hundred ml as a monthly 3745-1-32 2 geometric mean, based on not less than five samples per month, nor exceed two hundred forty per one hundred ml in any sample. For the months of November to April, the maximum allowable level of fecal coliform bacteria shall not exceed two thousand per one hundred ml as a geometric mean based on not less than five samples per month.

bA minimum of 5.0 mg/l at any time shall be maintained during the April fifteen to June fifteen spawning season.

cGross total alpha particle activity (including radium-226, but excluding radon and uranium) shall not exceed fifteen picocuries per liter (pci/l) and combined radium-226 and radium-228 shall not exceed four pci/l. The concentration of total gross beta particle activity shall not exceed fifty pci/l. The concentration of total strontium-90 shall not exceed eight pci/l.

3 OMZA = outside mixing zone average. Criteria in the "Intakes" column apply within five hundred yards of drinking water intakes. Criteria in the "Elsewhere" column apply at all other locations.

4The criteria for this chemical apply to the sum of all dinitrophenols.

5Criteria for this chemical are based on a carcinogenic endpoint.

6The criterion for this chemical applies to the sum of aldicarb, aldicarb sulfone and aldicarb sulfoxide.

7The criterion for this chemical applies to the sum of chloroacetic acid, dichloroacetic acid and trichloroacetic acid.

8The criteria for this chemical apply to the sum of alpha-endosulfan, beta-endosulfan and endolsufan sulfate.

9The criteria for this chemical apply to the sum of endrin and endrin aldehyde.

aThis criterion is the maximum contaminant level (MCL) developed under the "Safe Drinking Water Act".

bEquivalent 25°C specific conductance values are 1200 micromhos/cm as a maximum and 800 micromhos/cm as a thirty-day average.
