What this rule does

The proposed rules from the Idaho Department of Agriculture address invasive species and noxious weeds by removing the restriction on watercraft in a specific area of the Snake River for Quagga mussels and adding Golden mussels to the Emergency Detection Rapid Response Invasive Species list. These changes aim to enhance prevention and response efforts without imposing any new fees or negatively impacting the state general fund.

Page 2 of 2 IDAPA 02 – DEPARTMENT OF AGRICULTURE 02.06.09 – RULES GOVERNING INVASIVE SPECIES AND NOXIOUS WEEDS DOCKET NO. 02-0609-2503 NOTICE OF RULEMAKING – PROPOSED RULE AUTHORITY: In compliance with Section 67-5221(1), Idaho Code, notice is hereby given that this agency has initiated proposed rulemaking procedures. The action is authorized pursuant to Sections 22-1907, 22-2004, 22-2006, 22-2403, and 22-2412, Idaho Code. PUBLIC HEARING SCHEDULE: Apublic hearing concerning this rulemaking will be held as follows: Monday, November 17, 2025 10:00am – 11:00am Idaho State Department ofAgriculture 2270 Old Penitentiary Road Boise, ID 83714 Join by Virtual Meeting link found here Or on www.townhall.idaho.gov The hearing site(s) will be accessible to persons with disabilities. Requests for accommodation must be made not later than five (5) days prior to the hearing, to the agency address below. DESCRIPTIVE SUMMARY: The following is a nontechnical explanation of the substance and purpose of the proposed rulemaking: The purpose of this proposed rule is two-fold. First, to remove the previous prohibition of watercraft from the treatment area for Quagga mussel on the Snake River from Hansen Bridget to Pillar Falls. Second, add Golden mussel to the Emergency Detection Rapid Response (EDRR) Invasive Species list. Golden mussel is an aggressive bivalve aquatic mussel that has been found in California water delivery systems. Infestations have already impacted on the delivery of water for irrigation and municipal use, and treatment efforts are already with the current quagga mussel infestation found in Idaho. Adding Golden mussel to the EDRR list ensures adequate legal authority for prevention and response efforts in Idaho. Additionally, These rules mirror the temporary rule in Docket No. 02-0609-2502, which was immediately needed to protect public health and safety and reduce a regulatory burden. FEE SUMMARY: The following is a specific description of the fee or charge imposed or increased: No fee is being imposed or changed because of this rulemaking. FISCAL IMPACT: The following is a specific description, if applicable, of any negative fiscal impact on the state general fund greater than ten thousand dollars ($10,000) during the fiscal year as a result of this rulemaking: There is no fiscal impact on the General Fund or dedicated funds because of this rulemaking. NEGOTIATED RULEMAKING: Pursuant to Section 67-5220(1) and 67-5221(1)(j), Idaho Code, negotiated rulemaking was not feasible to conduct because of the immediate need to release the quarantine on the treatment area IdahoAdministrative Bulletin Page 22 November 5, 2025 – Vol. 25-11 DEPARTMENT OF AGRICULTURE Docket No. 02-0609-2503 Rules Governing Invasive Species & Noxious Weeds Proposed Rulemaking to allow access to the river. In addition, it was not feasible because the department needs the immediate listing of Golden mussel to ensure authority for prevention efforts, including watercraft inspection. INCORPORATION BY REFERENCE: Pursuant to Section 67-5229(2)(a), Idaho Code, the following is a brief synopsis of why the materials cited are being incorporated by reference into this rule: No materials are incorporated by reference.
