Agriculture committee approves a package of Idaho State Department of Agriculture rules; lawmakers press for clarity on chemigation and groundwater testing

Boise — The Idaho Senate Agricultural Affairs Committee approved seven rule dockets from the Idaho State Department of Agriculture (ISDA) on Jan. 23, advancing revisions the department described as clarifications, duplicative-language removals and updates to federal and national standards.

Director Chanel Tewall told the committee she wants the 0-based regulation (ZBR) review to be a meaningful, line-by-line conversation with the regulated community rather than a simple cut-and-paste exercise. "The ZBR process ... is only as good as an agency chooses to make it," Tewall said, adding the department aims to balance legal requirements with practical customer service for farmers and ranchers.

Why it matters: The package includes rule changes that affect licensing and compliance for pesticide applicators and chemigation operators, groundwater pesticide-monitoring procedures, weights-and-measures standards incorporated from NIST, and updates to organic certification rules that must align with federal standards. Several rules implement changes required or enabled by recent state law and federal guidance and will affect how producers obtain licenses, how the state samples private wells for pesticide detections, and which national handbooks the state references for technical standards.

What the committee approved

- Bonded warehouse rules (docket referenced in committee materials as 4122401): ISDA removed duplicative language where statute already prescribes the requirement and clarified an acronym used in rule text. Committee discussion focused on electronic warehouse receipts and ensuring receipts cannot be duplicated for the same lot. ISDA said electronic receipts are used for crop collateral lending and duplicate receipts could create loaning problems. The committee adopted the docket by voice vote.

- Weights and measures (incorporation-by-reference update, NIST Handbook update; docket recorded as 202142401): The department updated its incorporation by reference from NIST Handbook 2023 to 2024 to keep Idaho aligned with national measurement standards used in commerce. Committee members asked about adopting the "latest specifications" language in some citations; ISDA said the underlying code and citations define the required standard.

- Pesticide management plans for groundwater protection (docket 203012401): ISDA described removals of duplicative or descriptive language already covered in Title 22, Chapter 34 of Idaho Code and clarified where definitions and prohibitions remain in statute rather than rule. Administrator Brian Slabaugh summarized the groundwater monitoring program and said the department has collected roughly 1,300 water samples over the last five years and tests for a panel of about 89 active ingredients, working with up to about 300 well owners in a year. "We test for a group of about 89 active ingredients ... over the last 5 years we have about 1,300 water samples that we have analyzed for pesticides," Slabaugh said. The committee adopted the docket by voice vote.

- Pesticide and chemigation use and application (docket 203032402): The rule recasts certification and training requirements for applicators and implements changes required by House Bill 549 (2024), which separated chemigation licensing from the federal licensing categories. ISDA said the rewrite simplifies the path to a chemigation applicator license by allowing multiple department-approved methods to demonstrate competence (for example, exam, department-approved training, or demonstrated on-site competency). Slabaugh told the committee the department has partnered with the University of Idaho on training modules and is developing Spanish-language materials; the rule also broadens apprentice categories in response to industry hiring difficulties. The committee adopted the docket by voice vote.

- Produce safety (docket 205012401): The rule aligns Idaho's state-run produce safety program with the federal Food Safety Modernization Act (FSMA) requirements and removes duplicative language where the Code of Federal Regulations already prescribes standards. ISDA noted that certain commodities are exempt or covered differently (example given in committee: onions are covered; potatoes are not) and that the rule is intended to reflect the risk-based federal framework. The committee adopted the docket by voice vote.

- Registrations and licenses (commercial feeds, fertilizers, soil and plant amendments; docket 2622401): ISDA incorporated updated publication dates for the 2024–25 American Association of Feed Control Officials and the American Association of Plant Food Control Officials manuals. The manuals establish standardized definitions and labeling conventions that allow regulators and manufacturers to verify product guarantees and component statements across states. ISDA said the updates contain no additional regulatory impact. The committee adopted the docket by voice vote.

- Organic food products (docket 206332401): The department updated the incorporated USDA organic program standard to the current publication date to preserve consistency for certification. ISDA said the organic certification program is voluntary, that adopting current federal standards is necessary for state certification to remain valid, and that most changes in the federal documents are definitional or timing adjustments (for example, transition periods for dairy animals). The committee adopted the docket by voice vote.

Committee questions and clarifications

Senators asked ISDA staff to clarify several operational points rather than to block the rules. Questions included: - Electronic warehouse receipts: Senators asked why the rule language disallows a paper and electronic receipt for the same commodity lot; ISDA explained that electronic receipts are required for crop collateral loans and duplicates could allow two loans on the same crop. - Bond amounts and statutory cross-reference: Committee members asked whether the bond-calculation language in the bonded-warehouse rule merely repeats statute; ISDA said the citation was left to help users locate the statutory formula but agreed it could be reworded if the committee wished. - Groundwater sampling frequency and consent: Senators asked how often wells are sampled and whether ISDA can sample private wells without consent. Slabaugh said the program works by agreement with private well owners, conducts an annual sampling plan, has sampled roughly 1,300 wells over five years and typically works with up to about 300 well owners in a year. If an elevated detection prompts a response, ISDA may sample more frequently and work with well owners on quarterly monitoring where needed. - Chemigation licensing and reading labels: Senators pressed ISDA on how the new pathways will accommodate operators who may not read English well or who have literacy challenges. Slabaugh said ISDA is developing a Spanish-language training and that department-approved on-site demonstrations are an alternative for applicants who cannot complete written exams.

Votes at a glance

All seven dockets were adopted by voice vote; no roll-call tallies were recorded in the committee transcript. Each approval was moved and seconded and carried without recorded opposition.

What comes next

ISDA staff and senators requested follow-ups in writing on several technical points: (1) additional detail on the electronic warehouse-receipt language and how duplication is prevented; (2) clearer citation or rewording regarding bond-calculation language in the bonded-warehouse rule; and (3) a summary of substantive changes in the organic standard (ISDA staff agreed to post change summaries on the department website and provide them to committee members). ISDA told the committee those clarifications will be provided after the meeting.

Ending

Committee Chair Senator Nichols returned the gavel after the approvals and adjourned the meeting. The ISDA presenters thanked the committee for time and said they would follow up with requested written clarifications.
