Water Quality: Docket No. 58-0102-1801

This rulemaking was initiated to update Idaho’s human health criteria for arsenic. Negotiated under Docket No. 58-0102-1801 and proposed under Docket No. 58-0102-2201.

Status of Rulemaking

Proposed rule published in the March 2, 2022 Idaho Administrative Bulletin under Docket No. 58-0102-2201. Comment deadline April 1, 2022.

Overview

This rulemaking has been initiated to update Idaho’s human health criteria for arsenic.

In May 2016, EPA entered into a Consent Decree with Northwest Environmental Advocates to reconsider EPA’s 2010 approval of Idaho’s human health criteria for arsenic. In September 2016, EPA disapproved Idaho’s human health criteria of 10 µg/L arsenic for both consumption of fish only and consumption of fish & water. The Consent Decree requires that EPA propose new human health criteria for arsenic by November 15, 2018, and that EPA either approve Idaho’s submittal of revised human health criteria for arsenic or promulgate federal criteria by July 15, 2019. In June 2018, the Court granted the Unopposed Motion to Modify Consent Decree, extending the November 15, 2018, and July 15, 2019, deadlines to November 15, 2022, and November 15, 2023, respectively.

This rulemaking will enable Idaho to adopt human health criteria for arsenic under state rulemaking and may prevent federal promulgation of criteria for Idaho by EPA.
