  • IDEQ is evaluating local and regional fish consumption rates to determine whether Idaho's statewide water quality criteria are protective of designated uses and, if the current criteria are not protective, to determine appropriate new criteria. The rulemaking will derive the human health criteria for acrolein and phenol, and will set a human health criterion for copper based on drinking water standards.

    On May 10, 2012, EPA disapproved 167 of Idaho's proposed human health water criteria for 88 toxic pollutants. In determining the proposed criteria, IDEQ used the nationally recommended fish consumption rate, 17.5 grams per day. EPA determined that IDEQ did not consider several sources of information suggesting some Idahoans consume more fish than the national average and the national default fish consumption rate of 17.5 grams per day was not applicable in Idaho. EPA suggested IDEQ should use a higher fish consumption rate in determining its human health water criteria and thus the water quality standards should be stricter.

    Rulemaking meetings are scheduled for December 10, 2013, from 9 a.m. to 12:30 p.m. (mountain time) in Boise, Pocatello, Lewiston, and Coeur d'Alene. For those who cannot participate by attending the meetings, written comments may be submitted to IDEQ.
