• Adjourn

Discussion

• Notes from November 17 were accepted as written.

• Research Priorities (SB). SB circulated the two previous research priorities lists and opened it up to 

 discussion. The LS discussed modifying several of the previous priorities for the Spring 2021 posting. 

 A member asked about GMO persistence in compost and manure, which the Chair noted would be 

 addressed in Crops. Members discussed the methionine research priority, and all agreed that it is 

 critical to keep on the list. The group discussed the process by which the priorities are disseminated to 

 the research community and NOP added that a rep from NIFA may be invited to the Spring meeting to 

 provide an update to the Board and community. 

• 2023 Sunset: Activated charcoal (SR). The lead summarized the uses and manufacture of activated 

charcoal, noting that it was recently added to the National List based on a recommendation from 2002 

and is undergoing its first sunset review. There is a pending technical report that will be available for 

the Spring meeting. 

• 2023 Sunset: Sodium chlorite, acidified 205.603(a)(28) & 205.603(b)(9) (KH). The lead noted that 

 sodium chlorite was recently added to the National List based on a recommendation from 2002 and is 

 undergoing its first sunset review. The HS will discuss the draft reviews on the next call, January 5.

• 2023 Sunset: zinc sulfate (JB). The lead summarized the uses, manufacture, and environmental 

concerns of zinc sulfate, and noted that this is its first sunset review. Zinc sulfate was approved as a 

way to limit the use of copper and although it can accumulate in soil, is considered more benign than 

alternatives.

• Additional items. None.

• The meeting was adjourned.

Discussion

• Notes from September 15 were reviewed and accepted as is. 

• Public comments/review roles for Fall meeting. 

o The LS Chair suggested timing for discussing various documents, allotting the bulk of the time for 

the fenbendazole proposal. 

• Public comments. The group discussed comments about fenbendazole and EPA List 4 inerts. Some 

commenters expressed concern about residual amounts of fenbendazole in eggs. Stakeholders also 

provided feedback about List 4 inerts. Some are concerned that it will destabilize the industry. With 

support from NOP, EPA, and stakeholders, the NOSB will move ahead with its review with the 

intention of finding a replacement or solution for a list that is no longer supported by EPA, 

acknowledging that it could take a long time until it is implemented. 

• Additional items. 

o The Crops Subcommittee is awaiting a response from the petitioner about one of its two chitosan. 

Since the LS is reviewing chitosan as processing aid in the production of livestock feed, the 

Subcommittees are working together and sharing information. 

• The meeting was adjourned.

petition assigned to the Livestock Subcommittee to permit chitosan as a flocculant for manufacturing

livestock feed. The petition is available on the NOP website. RG joined the Livestock call to discuss the

status of two other petitions for chitosan that are currently under review by the Crops Subcommittee

(one for use as a plant disease control and one for use as a flocculant to manufacture crop 

fertilizers/soil amendments). A technical report was recently completed on chitosan with an emphasis 

on use for plant disease control (also available on the NOP website). A member noted that the petition

claims the amount of chitosan in a final product is minuscule. Members questioned whether chitosan

would be used to manufacture organic feed if it were added to the National List. Members will discuss 

the petition in more detail on the next call. NPP volunteered to take the lead on the review. RG offered 

to share information learned from the Crop Subcommittee’s reviews.

• Additional items. The group discussed the fenbendazole proposal and potential options to limit its use 

(and reduce concerns of residues) through an annotation, such as limiting its use to birds that have not 

yet begun to produce eggs. The petition is on the agenda for the full Board meeting in October. 

• The meeting was adjourned.

Discussion

• Notes from July 7 notes were accepted as written.

• Fenbendazole (SB). The lead discussed the proposal to annotate fenbendazole to include use in 

poultry. 

Classification: Fenbendazole is already on the National List and is classified at synthetic nonagricultural.

Motion to amend the listing for fenbendazole to include at 7 CFR §205.603 (23)(i): fenbendazole - for 

use in laying hens or replacement chickens intended to be laying hens 

Motion by: SB

Seconded by: KH

Yes: 4 No: 2 Abstain: 0 Absent: 0 Recuse: 0 

• 2022 Sunsets: EPA List 4 - Inerts of Minimal Concern (SR). The lead summarized the previous work on 

EPA List 4 Inerts, which is a defunct listing that EPA no longer maintains. The Crops Subcommittee is 

also reviewing this sunset listing. The lead noted that of the ~360 inerts on List 4, approximately 153 

are on the EPA Safer Choice List, and if the NOSB were to recommend removal of the listing from the 

National List, that could leave a number of products that would have to be reformulated. There is wide 

support to move this project forward, with support from the NOSB, NOP, and the community. Public 

comment indicated that leaving the defunct listing on the National List stifles innovation and 

disincentivizes the production of safer, less toxic products. 

Motion to remove EPA List 4 - Inerts of Minimal Concern at §205.603 

Motion by: SR

Seconded by: SB

Yes: 2 No: 4 Abstain: 0 Absent: 0 Recuse: 0 
• 2022 Sunsets: Formic acid (NPP). The lead summarized the use of formic acid including health and 

human effects, which, with proper precautions, are minimal. Formic acid is fairly non-toxic, and is used 

internationally. The Subcommittee and commenters supported relisting. 

Motion to remove formic acid at § 205.603 

Motion by: NPP

Seconded by: SR

Yes: 0 No: 6 Abstain: 0 Absent: 0 Recuse: 0 

• 2022 Sunsets: Strychnine (NPP). The lead summarized the uses of strychnine as well as previous 

comments. Strychnine is used as a rodenticide, and is considered a violent substance that causes pain 

and suffering. Additionally, it is dangerous to mammals and humans. It is listed at 205.602 - prohibited 

from use in organic agriculture, and the Livestock Subcommittee voted for continued prohibition. 

Motion to remove strychnine at § 205.603 

Motion by: NPP

Seconded by: JB

Yes: 0 No: 6 Abstain: 0 Absent: 0 Recuse: 0 

• Additional items. None

• The meeting was adjourned.

Discussion

• Notes from June 2 were accepted as written.

• Fenbendazole (SB). The lead reviewed the TR sufficiency criteria and the TR was deemed sufficient.

The lead will inform the NOP and the group will discuss the draft proposal on the next call.

• 2022 Sunsets: Butorphanol (SR). The lead summarized the use of butorphanol as well as the public 

comments received at the Spring meeting. He noted that there are no effective alternatives to 

butorphanol, and the Subcommittee moved to a vote to relist. 

Motion to remove butorphanol at §205.603

Motion by: SR

Seconded by: DS

Yes: 0 No: 5 Abstain: 0 Absent: 1 Recuse: 0 

• 2022 Sunsets: Poloxalene (DS). The lead summarized the use of poloxalene to control bloat, and noted 

that although there are natural alternatives, they are found to be ineffective, especially for severe 

cases. Two commenters raised questions but did not offer evidence of alternatives. Members noted 

that although poloxalene is synthetic it is used infrequently and is important for use on farms.

hydroxide and members suggested minor modifications. The LS will submit the document for 

posting for the Spring meeting. 

• 2022 Sunsets: EPA List 4 - Inerts of Minimal Concern (SR). The Livestock Subcommittee had a 

lengthy discussion about the EPA List 4 inerts listing, which is inactive, and has been for about 8 

years. The lead noted that the Executive Committee also discussed this issue on the December 

call, and NOP is supportive of the NOSB work to rectify the discrepancy. Members discussed the 

which could include the SCIL list. The group also discussed a memorandum of understanding 

(MOU). The lead added some questions for public comment and reviewed them with the 

members. The LS will forward this to NOP for posting for the Spring meeting. 

• 2022 Sunsets: Excipients (SB). The lead summarized the draft review including uses and 

potential GMOs. The LS will add some questions targeted at certifiers about how excipients are 

reviewed, and if there are any specific excipients that are of more concern than others. The LS 

will forward this to NOP for inclusion at the Spring meeting. 

• Other items. The LS submitted questions for the Fenbendazole TR to NOP, who will send to the 

contractor. 

• The meeting was adjourned.
