3745-1-34 Water quality criteria for the Ohio river drainage basin.

(A) This rule applies in addition to the requirements contained in rule 3745-1-07 of the Administrative Code to water bodies within the Ohio river drainage basin. Except as provided in paragraph (D) of this rule, the methodologies contained in rule 3745-1-36 of the Administrative Code shall be used when adopting or revising numeric aquatic life water quality criteria and when implementing the narrative aquatic life water quality criteria contained in rule 3745-1-04 of the Administrative Code for water bodies located in the Ohio river drainage basin. Any methodologies and procedures acceptable under 40 C.F.R. 131 may be used when developing or revising human health water quality criteria or implementing narrative criteria contained in rule 3745-1-04 of the Administrative Code for water bodies located in the Ohio river drainage basin.

(B) The chemical-specific criteria listed in this rule apply as "Outside Mixing Zone Averages". For the purpose of setting water quality based effluent limits, these criteria shall be met after the effluent and the receiving water are reasonably well mixed as provided in rules 3745-2-05 and 3745-2-08 of the Administrative Code.

(C) The water quality criteria adopted in, or developed pursuant to, this rule shall apply as follows:

(1) To protect against adverse reproductive effects on wildlife, "the Outside Mixing Zone Average" criteria for polychlorinated biphenyls is 1.0 ng/l. In addition, any whole sample of any representative aquatic organisms shall not exceed 0.64 mg/kg (wet weight). These criteria, or site-specific modifications thereof, shall apply to all water bodies of the Ohio river drainage basin.

(2) The water quality criteria for protection of human health, or site-specific modifications thereof, are "Outside Mixing Zone Average" water quality criteria and shall apply as follows:

(i) The "Drinking" water quality criteria for the protection of human health shall apply to all water bodies located in the Ohio river drainage basin within five hundred yards of drinking water intakes.

(ii) The "Nondrinking" water quality criteria for the protection of human health shall apply to all water bodies located in the Ohio river drainage basin other than those specified in paragraph (C)(3)(i) of this rule.

(D) For any pollutant for which it is demonstrated that a methodology or procedure cited in this rule is not scientifically defensible, the director may apply an alternative methodology or procedure acceptable under 40 C.F.R. 131 when developing water quality criteria.
