(p) Toxic Substances:
(A) Toxic substances shall not be introduced above
natural background levels in the waters of the state in
amounts, concentrations, or combinations which may be
harmful, may chemically change to harmful forms in the
environment, or may bioaccumulate to levels that adversely
affect public health, safety, or welfare; aquatic life; or other
designated beneficial uses.
(B) Levels of toxic substances shall not exceed the most
recent criteria values for organic and inorganic pollutants
established by EPA and published in Quality Criteria for
Water(1986). A list of the criteria is presented in Table 20.
(C) The criteria in paragraph (B) of this subsection shall
apply unless data from scientifically valid studies demon-
strate that the most sensitive designated beneficial uses will
not be adversely affected by exceeding a criterion or that a
more restrictive criterion is warranted to protect beneficial
uses, as accepted by the Department on a site specific basis.
Where no published EPA criteria exist for a toxic substance,
public health advisories and other published scientific liter-
ature may be considered and used, if appropriate, to set
guidance values.
(D) Bio-assessment studies such as laboratory bioassays
or instream measurements of indigenous biological commu-
nities, shall be conducted, as the Department deems neces-
sary, to monitor the toxicity of complex effluents, other
suspected discharges or chemical substances without
numeric criteria, to aquatic life. These studies, properly
conducted in accordance with standard testing procedures.
may be considered as scientifically valid data for the pur-
poses of paragraph (C) of this subsection. If toxicity occurs,
the Department shall evaluate and implement measures
necessary to reduce toxicity on a case-by-case basis.
