Discussion

• November 16, 2021 notes were accepted as written.

• Discuss 2024 Sunsets:

o Elemental sulfur (BC) - The lead discussed the commercial availability of elemental sulfur in the 

United States for industrial purposes, of which agricultural is a small subset. The lead 

summarized public comments submitted during, and international acceptance as of, the last 

NOSB sunset review. The lead also summarized environmental issues, livestock health concerns, 

and the 2017 Technical Report. The lead presented stakeholder questions to include in the 

document. The lead will send the document to the LS Chair.

• Additional Items 

o Research Priorities - Members discussed several research priority line items, including livestock 

parasites. Members would like the NOSB to request a report from NIFA on how NOSB research 

priorities have been disseminated. Research Priorities will be requested as an agenda item in the 

next Executive Committee call.

o Assign and reassign leads as needed - Leads will be assigned where needed after the new NOSB 

members are announced.

o International Acceptance - During the discussion of elemental sulfur, members discussed how 

international acceptance information is collected by the NOSB for sunset reviews. Members 

agree that the NOSB sunset review process could use support in this area. Support for the NOSB 

in terms of international acceptance of substances will be brought to the Compliance, 

Accreditation, & Certification Subcommittee (CACS), which is scheduled to discuss the Human 

Capital Management: NOSB Support proposal at their next call.

Discussion

• October 5th, 2021 notes were accepted as written.

• Discuss Sunsets:

o 2024 Sunset: Glucose (MJ) - The lead discussed the 2015 and 2017 sunset reviews. A new 

Technical Report (TR) is pending. Current sunset review content may change upon receipt of this 

pending TR. In the 2015 and 2017 sunset reviews there were no highlighted environmental or 

human health concerns and there was general support for relisting. LS members discussed the 

usage of glucose in organic production. A member questioned the commercial availability of 

nonsynthetic glucose, and the members discussed including this as a stakeholder question. The 

lead will rewrite the draft and resend to the LS Chair.

o 2024 Sunset: Tolazoline (SB) - The lead discussed the use of tolazoline in organic production its 

relationship to xylazine, international acceptance, environmental issues, and the most recent 

sunset review. The lead asked if members had any additional questions for stakeholders and 

received none. LS will submit the review to NOP for the Spring meeting.

• Additional Items

Discussion

• Notes from June 15 were accepted as written.

• Research Priorities (KH for SB). The LS Chair will reach out to members to finalize the priorities list and

send them to the Materials Subcommittee. 

2023 Sunset: Activated charcoal (BC). The lead summarized the uses of activated charcoal, noting it is 

synthetic. Commenters, including a veterinarian, were supportive of relisting, and indicated that it was 

in routine use and essential. 

Motion to remove activated charcoal from the NL 

Motion by: BC

Seconded by: KH

Yes: 0 No: 3 Abstain: 0 Absent: 2 Recuse: 0 

• 2023 Sunset: Mineral Oil (KH for SB). The LS Chair summarized the substance review and public 

comment from the Spring. Commenters were supportive of relisting.

Motion to remove mineral oil from the NL 

Motion by: KH

Seconded by: BC

Yes: 0 No: 3 Abstain: 0 Absent: 2 Recuse: 0 

• 2023 Sunset: Sodium chlorite, acidified (KH). The lead summarized the substance which is listed in 

two places; At 205.603(a)(28) and 205.603(b)(9). Acidified sodium chlorite is used infrequently, but is 

essential when it is needed. The members discussed the two listings, specifically that they seemed

redundant and suggested that the LS may revisit the need for both listings at a future date. The LS 

voted on the two listings separately. 

Motion to remove sodium chlorite, acidified from the NL at 205.603(a)(28)

Motion by: KH

Seconded by: NPP

Yes: 0 No: 3 Abstain: 0 Absent: 2 Recuse: 0

Motion by: KH

Seconded by: NPP 

Yes: 3 No: 0 Abstain: 0 Absent: 2 Recuse: 0 

• 2023 Sunset: Zinc sulfate (BC). The lead summarized zinc sulfate and indicated that it is an alternative 

to copper sulfate. A member added information about how and why it would be used and that a 

producer would likely use it in consultation with a veterinarian.

Motion to remove zinc sulfate from the NL 

Motion by: BC

Seconded by: KH

Yes: 0 No: 3 Abstain: 0 Absent: 2 Recuse: 0 

• Additional items. Kaolin pectin was moved to the August 3 call, as the LS is waiting for the TR

Agenda

Discussion

• Notes from June 1 were accepted as written.

• 2023 Sunset: Calcium borogluconate (MJ). The lead summarized the review, highlighting the updates 

made since the Spring 2021 posting. The NOP provided additional feedback from FDA regarding this 

substance, since it was recommended for addition to the NL in 2002 and only recently added to the 

National List (NL). The lead indicated that calcium borogluconate is compatible with a system of 

sustainable agriculture, and the majority of stakeholders were in favor of its inclusion. 

Motion to remove calcium borogluconate from the NL

Motion by: KH

Seconded by: MJ 

Yes: 0 No: 3 Abstain: 0 Absent: 2 Recuse: 0 

• 2023 Sunset: Calcium propionate (SB). The lead highlighted the additions to the document from the 

Spring 2021 meeting, including a summary of public comment. 

Motion to remove calcium propionate from the NL

Motion by: KH

Seconded by: SB

Yes: 0 No: 4 Abstain: 0 Absent: 1 Recuse: 0 

• 2023 Sunset: Chlorine materials (NPP). There were no substantive changes to the Spring document, 

except the lead combined all four chlorine materials into one document instead of splitting the out 

individually. The LS supports relisting of chlorine materials. Chlorine materials are also under review in 

Handling and Crops, and the three leads did converse, the uses in each section are fundamentally 

different. The LS Chair noted that the Handling Subcommittee also discussed chlorines in the context 

of the broader picture of sanitizers.

Discussion

• Notes from May 18 were accepted as written.

• 2024 Sunsets - TR requests

• Chitosan - processing aid in the production of livestock feed (NPP). The lead summarized the petition and 

noted that the Crops Subcommittee is also reviewing a chitosan petition submitted by the same petitioner. The 

Livestock Subcommittee chose to align its determination with the Crops Subcommittee to send the petition back 

to the petitioner unreviewed. The LS sent additional questions to the petitioner and did not receive a response

and feels it cannot move forward with a review at this time. NOP will relay this decision to the petitioner. 

• 2023 Sunset: Nutritive supplements (NPP). The lead summarized the substance and the LS moved to a vote.

• Adjourn

Discussion

• Notes from February 16 were accepted as written.

• Mineral Oil (SB). The lead reviewed the TR and found it sufficient, although she noted that upon initial 

review it may not address in detail the specific question about impaction. The lead mentioned a potential 

discrepancy between certifiers due to the language in the annotation at 205.603(a)(20) versus what is 

listed at 205.603(b)(7), and that with this review the LS is hoping to clarify. A member asked about 

alternatives, which is a question the LS included in the Spring review. The LS Chair will inform the NOP 

that the TR was found sufficient. 

• Propylene glycol (MJ). The lead reviewed and summarized the TR, and the LS found it sufficient. The LS 

Chair will inform the NOP that the TR was found sufficient. 

• Additional items. 

o The LS Chair will meet with the lead reviewer for activated charcoal to talk about the TR. The LS 

will discuss the TR sufficiency on April 6.

o A member asked about the recent NOP request to review lithothamnion, which will be reviewed 

by the Crops Subcommittee as it is specific to wild crop standards. 

• The meeting was adjourned.
