Rulemaking Documents Required by Idaho Administrative Procedure Act
This rulemaking has been initiated to (1) revise water quality standards based on stakeholder comments and concerns regarding the implementation of the bacteria criteria, and (2) delete obsolete rule language.
Address Concerns Regarding Implementation of Bacteria Criteria
During 2019 legislative review of pending rule docket 58-0102-1802, stakeholders raised concerns regarding the implementation of Idaho bacteria criteria as presented in the pending rule. On March 18, 2019, the House adopted House Concurrent Resolution No. 23 (HCR23) to reject Subsection 251.02, adopted as a pending rule under Docket No. 58-0102-1802. On March 19 2019, HCR23 was introduced in the Senate and referred to the Senate Health & Welfare Committee. HCR23 was not reported out of committee; the pending rule docket became final and effective on April 11, 2019. This rulemaking seeks to revise Idaho Water Quality Standards to address the stakeholders’ unresolved concerns.
This rulemaking will consider revisions to bacteria criteria language in Section 251 regarding the geometric mean criterion for E. coli and enterococci and whether to include data sufficiency clauses or statements addressing the minimum sample number for assessing compliance with the recreational criteria. DEQ will consider revision of statistical threshold values (STV) as criteria. The STV is a concentration that is not to be exceeded more frequently than 10% of valid samples collected in a 30-day period. Stakeholders expressed concern with the use of the STV for determining beneficial use support.
Delete Obsolete Rule Language
DEQ proposes to delete Subsection 260.02 including footnotes. Subsection 260.02, Variances from Water Quality Standards, Specific Variances, was adopted by the Idaho Board of Environmental Quality in 2000 and approved by the Idaho Legislature in 2001 (Docket No. 58-0102-0002). On May 29, 2003, DEQ submitted the final rule to EPA. On May 7, 2010, EPA disapproved the variance; therefore, Subsection 260.02 is not effective for Clean Water Act purposes and has been identified for deletion.
