Water Quality: Docket No. 58-0102-1502 - Negotiated Rulemaking/Guidance Development

Rulemaking initiated to update DEQ’s existing hardness dependent criteria by using EPA’s 2007 304(a) copper criteria. This update is a Reasonable and Prudent Alternative identified in National Oceanic and Atmospheric Administration’s (NOAA) biological opinion (BiOp) on Idaho’s criteria for toxic substances to support aquatic life.

Rulemaking Documents Required by Idaho Administrative Procedure Act

Overview

This rulemaking has been initiated to update DEQ’s existing hardness dependent criteria by using EPA’s 2007 304(a) copper criteria. This update is a Reasonable and Prudent Alternative identified in National Oceanic and Atmospheric Administration’s (NOAA) biological opinion (BiOp) on Idaho’s criteria for toxic substances to support aquatic life.

The toxicity of copper to aquatic life is highly variable depending on physicochemical factors within a water body. The effect of hardness on metal toxicity has long been acknowledged as one such factor and is reflected in DEQ’s current hardness dependent criteria, whereby the acute and chronic criteria are determined based on the total hardness of the receiving water body. However, DEQ’s current hardness dependent criteria do not take into account the effects of other physicochemical properties of the receiving water body which affect toxicity, leading to DEQ’s current criteria being either over- or under-protective of aquatic life.

This action is identified in NOAA’s biological opinion (BiOp) on Idaho’s criteria for toxic substances to support aquatic life. This BiOp concluded that the current copper criteria (as well as other toxics criteria) were under-protective of aquatic life support and would result in adverse modification of critical habitat. NOAA’s recommendation is to use EPA’s 2007 304(a) copper criteria, which uses other physicochemical properties of the water (e.g., pH, DOC, etc.) to predict water-body specific criteria known as the Biotic Ligand Model (BLM). NOAA has called for state adoption and EPA approval or EPA promulgation of these criteria by May 2017. Because of this, DEQ’s 2014 triennial review identified revision of the aquatic life criteria for copper as a high priority. By adopting a copper criterion based on the BLM, DEQ will be able to use the most current state of the science to ensure that the criteria are more precise and are neither unnecessarily burdening dischargers nor increasing risk to aquatic life.

In short, this rule will replace the existing hardness dependent criteria for copper with a similar, albeit more detailed, modeled approach. DEQ will also explore an alternative, simplified version of the BLM, using a multiple linear regression model for copper toxicity which could be adopted as an equation. DEQ anticipates there may also be need for language dealing with how the BLM for copper is to be applied in situations where data on physiochemical properties of a water body are limited, such as default model inputs. Additionally, DEQ anticipates there may be need for language dealing with implementation of the BLM criteria for assessment and permitting purposes; e.g., providing a single reference value to account for the variability in multiple instantaneous criteria.

The text of the rule will be drafted by DEQ in conjunction with a negotiating committee made up of persons having an interest in the development of this rule. Idahoans that recreate in, drink from, or fish Idaho’s surface waters and all who discharge pollutants to those same waters may be interested in participating in this rulemaking.

Upon conclusion of negotiations, DEQ intends to publish a proposed rule for public comment in the summer of 2016 and then present the final proposal to the Idaho Board of Environmental Quality for adoption of a pending rule in the fall of 2016. If adopted by the Board, the rule will be reviewed by the 2017 Idaho Legislature.

Effective for Clean Water Act Purposes

Water quality standards adopted and submitted to EPA since May 30, 2000, are not effective for federal Clean Water Act (CWA) purposes until EPA approves them (see 40 CFR 131.21). This is known as the Alaska Rule. This rulemaking will be promulgated so that the existing rule, which continues to be effective for CWA purposes, remains in the Idaho Administrative Code until EPA approves the rule revisions. Notations explaining the effectiveness of the rule sections are also included. Upon EPA approval, the revised rule will become effective for CWA purposes and the previous rule and notations will be deleted from the Idaho Administrative Code. Information regarding the status of EPA review will be posted here.

Method of Participation/Negotiated Rulemaking

Those interested in participating in the negotiated rulemaking process are encouraged to attend the scheduled meeting at one of the following locations. Additional meetings will be scheduled if necessary. The meeting locations will be connected by telephone and web conferencing. Individuals interested in participating by telephone and web conferencing should contact Paula Wilson by the date provided in the table below. For those who cannot participate by attending the meetings, written comments may be submitted to Paula Wilson by e-mail or fax to (208) 373-0481.
