Wisconsin Statutes Health (Ch. 140 to 162) § 160.09. Establishment of enforcement standards; substances of public welfare concern

(a) If a single federal number exists for a substance, the federal number shall be the enforcement standard.

(b) If more than one federal number exists for a substance, the most recently established federal number representing the most current data shall be the enforcement standard.

(c) If no federal number exists for a substance, but there is a state drinking water standard, the state drinking water standard shall be the enforcement standard.

(d) If neither a federal number nor a state drinking water standard exists for a substance, the department shall establish an enforcement standard using all relevant and scientifically valid information available in technical literature concerning the substance and, if necessary, by comparison to similar compounds or classes of compounds.

(e) Notwithstanding pars. (a) and (b), the department may establish an enforcement standard different than the federal number if there is significant technical information which is scientifically valid and which was not considered when the federal number was established, upon which the department concludes, with a reasonable scientific certainty, that such a standard is justified. The department may change an enforcement standard previously adopted by utilization of a federal number. In evaluating the evidence for establishing an enforcement standard different than a federal number, the department shall consider the extent to which the evidence was developed in accordance with scientifically valid analytical protocols and may consider whether the evidence was subjected to peer review, resulted from more than one study and is consistent with other credible medical or toxicological evidence.
