Rulemaking Documents Required by Idaho Administrative Procedure Act


This rule making has been initiated to designate domestic water supply as a beneficial use in twelve water bodies where the Safe Drinking Water Information System indicates an active surface water intake and where domestic water supply is not currently designated.

In Sections 110 through 140, Domestic Water Supply (DWS) designations will be added to the “Other” column for twelve water body units where DWS is an existing use. Subsection 100.03.a. will be revised to clarify that the domestic water supply use is intended to protect water quality appropriate for drinking water supplies after treatment. In addition, Subsection 252.01 will be revised by deleting Subsections 252.01.a and b. Subsection 252.01.a. is unnecessary as it is redundant with the Idaho Rules for Public Drinking Water Systems, IDAPA 58.01.08 (Drinking Water Rules). Protection of surface waters from radioactivity is achieved with the narrative criteria in the Water Quality Standards, IDAPA Subsection 252.01.b. will be deleted because all public drinking water systems, regardless of size, are required to meet turbidity standards as part of the Drinking Water Rules. It is not necessary to include the surface water standard for turbidity in the Water Quality Standards.

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 Idaho’s surface waters, drink from public drinking water systems that use Idaho’s surface waters, 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 spring of 2018 and then present the final proposal to the Idaho Board of Environmental Quality (Board) in the fall of 2018 for adoption of a pending rule. If adopted by the Board, the rule will be reviewed by the 2019 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.
