National Organic Program: National List of Allowed and Prohibited 
Substances per October 2021, October 2022, and October 2024 
Recommendations (Crops and Livestock)

AGENCY: Agricultural Marketing Service, USDA.

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: This proposed rule would amend the U.S. Department of 
Agriculture's (USDA) organic regulations related to organic crop and 
livestock production. The proposed rule would provide additional tools 
to organic producers, allowing carbon dioxide in organic crop 
production and meloxicam as a pain treatment in organic livestock 
production. Additionally, this rulemaking would remove overly 
burdensome restrictions for methionine, an amino acid, in organic 
poultry feed and would affirm that sodium nitrate may be used as a 
fertilizer in organic crop production, with certain conditions to 
protect soil quality.

DATES: Comments must be received by May 22, 2026.

SUPPLEMENTARY INFORMATION:

I. Background

    This proposed rule would amend the USDA organic regulations to 
implement recommendations from the National Organic Standards Board 
(``NOSB'' or ``Board''). If adopted, this proposed rule would allow two 
additional synthetic substances to be used in organic crop and 
livestock production (carbon dioxide and meloxicam, respectively). 
Additionally, the proposed rule would remove current restrictions on 
the use of methionine, an amino acid, in organic poultry feed, thus 
allowing producers additional flexibility and making it unnecessary for 
organic poultry producers to track the amount of methionine fed to each 
poultry flock. Finally, the proposed rule would affirm that sodium 
nitrate, a natural fertilizer, is allowed for limited use in organic 
crop production by renewing the substance's listing on the National 
List of Allowed Substances for 5 years.

Authority

    The USDA Agricultural Marketing Service's (AMS) National Organic 
Program (NOP) administers the USDA organic regulations (7 CFR part 205) 
under the authority granted to it by the Organic Foods Production Act 
of 1990 (``OFPA'') (7 U.S.C. 6501-6524). This proposed rule would amend 
a portion of the USDA organic regulations known as the National List of 
Allowed and Prohibited Substances (or ``National List''), in accordance 
with the procedures and criteria set forth in the OFPA (7 U.S.C. 6503, 
6517, 6518). OFPA authorizes the Secretary to make amendments to the 
National List based on recommendations developed by the Board. OFPA 
authorizes the Board to develop recommendations for submission to the 
Secretary to amend the National List and to establish a process by 
which persons may petition the Board for the purpose of having 
substances evaluated for inclusion on, or deletion from, the National 
List.

II. General Information

A. Does this proposed rule apply to me?

    You may be affected by this proposed rule if you are engaged in 
organic crop and/or livestock production. Potentially affected entities 
may include, but are not limited to, the following:
     Organic crop and/or livestock producers;
     Individuals or business entities that are considering 
organic certification for crop and/or livestock production;
     USDA-accredited certifying agents, inspectors, and 
certification review personnel;
     Fertilizer, soil amendment, livestock feed supplement, and 
animal drug manufacturers;
     Material review organizations.
    This list is not exhaustive but identifies key entities that this 
rulemaking may affect. Other types of entities may also be affected. To 
determine whether you or your business may be affected by this action, 
you

[[Page 13783]]

should carefully examine the regulatory text and discussion below.

B. What should I consider as I prepare my comments for AMS?

    AMS seeks comment from the public and organic stakeholders 
regarding the proposed amendments. While all comments submitted are 
taken into consideration, the most effective comments:
     Clearly state a position (support, opposition, and/or 
requested modifications) on the proposed rule or specific parts of the 
proposed rule;
     Clearly identify which specific parts of the proposed rule 
a comment refers to;
     Explain why the commenter supports or opposes the proposed 
change;
     Describe the potential effects of the proposed rule using 
examples, data, or personal experience;
     If applicable, offer suggested alternatives to the 
proposed changes and/or regulatory text, and explain the reasoning for 
those suggested changes.
    Comments are invited on the entire proposed rule; however, AMS is 
especially interested in public input on the following questions:
    (1) Is the proposed regulatory language and accompanying discussion 
in this document clear enough to allow operations and certifying agents 
to comply with the proposed requirements?
    (2) Do the proposed amendments create any conflict with current 
USDA organic regulations or other Federal regulatory requirements?
    (3) Carbon dioxide:
    (a) Why is synthetic carbon dioxide necessary for the uses 
described in this proposed rule? What are the various sources of 
synthetic carbon dioxide that operations would be able to obtain? Which 
of these are sourced as a byproduct? Is there adequate supply of 
byproduct-sourced synthetic carbon dioxide in the market to meet the 
needs of the organic industry for either or both uses of described in 
this proposed rule?
    (b) Why is natural carbon dioxide insufficient or not available for 
the uses described in this proposed rule? Are other allowed natural or 
synthetic substances suitable as alternatives? Why or why not?
    (c) Should both listings of carbon dioxide at 7 CFR 205.601(a) and/
or 205.601(j) be annotated to only allow carbon dioxide sourced as a 
byproduct? Do producers and certifying agents have enough information 
to verify compliance with the proposed annotation?
    (4) Meloxicam:
    (a) Is the proposed annotation clear? Do veterinarians, producers, 
and certifying agents have the information they need to establish, 
document, and verify the proposed withdrawal period? If not, what 
additional information is necessary?
    (b) Should the annotation further restrict the use of meloxicam, 
such as by specifying a minimum withdrawal period for bovine species, 
and/or restricting non-bovine uses to disbudding and dehorning only?
    (c) AMS welcomes comments on the NOSB Livestock Subcommittee's 
technical analysis appendix published as part of the NOSB final 
recommendation.

III. Overview of Proposed Amendments

    The following provides an overview of the proposed amendments to 
the National List, along with the NOSB recommendations and AMS 
justifications for each proposed amendment. AMS welcomes comments on 
each proposed amendment. Comments received during the comment period 
will inform AMS's decisions for the final rule; specifically, whether 
the proposed amendments align with OFPA criteria and are justified. 
More information on the NOSB meetings can be found in section IV, 
RELATED DOCUMENTS.

A. Carbon Dioxide (Crops)

    AMS is proposing to add carbon dioxide to the National List at 7 
CFR 205.601(a) and 205.601(j) as a synthetic substance allowed for use 
in organic crop production to adjust the pH of irrigation water and for 
atmospheric adjustment in indoor crop production environments. This 
proposed rule would allow organic crop operations to use synthetic 
carbon dioxide, which is commonly sourced as a byproduct from various 
commercial processes. This AMS proposal follows two recommendations 
from the NOSB following its review of a petition, third-party technical 
reports, and public comments.
Background
    Synthetic carbon dioxide has been allowed for organic handling (7 
CFR 205.605(b)(10)) since the USDA organic regulations were first 
established (65 FR 80548, December 21, 2000). Organic handling 
operations use synthetic carbon dioxide to carbonate beverages, freeze 
foods, extract compounds, prevent spoilage in modified atmosphere 
packaging, and control pests in post-harvest storage of grains and 
produce. This AMS proposal would expand the current allowance of 
synthetic carbon dioxide to allow it in organic crop production for 
irrigation water treatment and as a plant and soil amendment.
    On November 30, 2020, Eco2Mix, Inc., a water treatment company, 
petitioned the NOSB to add carbon dioxide to the National List as an 
allowed synthetic substance for use in organic crop production.\1\ The 
petition requests carbon dioxide be allowed to adjust the pH of water 
used in crop irrigation systems in Sec.  205.601(a), and for use as a 
plant or soil amendment in Sec.  205.601(j).
---------------------------------------------------------------------------

    \1\ Eco2Mix, Inc. carbon dioxide petition, November 30, 2020, 
www.ams.usda.gov/sites/default/files/media/PetitionNOBCarbonDioxide2020.pdf.
---------------------------------------------------------------------------

    Many farming areas have alkaline (high pH) water sources that can 
hinder the efficiency of irrigation systems, reduce soil nutrient 
availability, and otherwise impair crop-growing conditions. To address 
these problems, carbon dioxide can be used to lower the pH of water. 
Dissolving carbon dioxide in water creates carbonic acid, which 
dissociates into hydrogen and bicarbonate ions, and the hydrogen ions 
acidify the water (lower the pH). By reducing the pH of alkaline 
irrigation water, operations can reduce mineral or algal buildup and 
prevent the clogging of irrigation system equipment (e.g., drip lines, 
emitters, sprinklers). Adjusting the pH of irrigation water can also 
help improve nutrient availability and plant health by establishing an 
ideal pH value (typically neutral or slightly acidic) for crop nutrient 
absorption.
    The petitioner states that the alternative substances currently 
allowed, such as natural carbon dioxide or synthetic sulfurous acid, 
are either not commercially available or are not as safe and effective 
as synthetic carbon dioxide. Natural carbon dioxide can be produced as 
a byproduct of fermentation (e.g., from ethanol production). However, 
the petition states that sources of natural carbon dioxide are not 
typically available in the market and could have impurities. The 
petition describes several sources of synthetic carbon dioxide and 
states that most sources reclaim or recapture carbon dioxide from 
processes that would otherwise release carbon dioxide into the 
atmosphere.
    Byproduct-sourced carbon dioxide is trapped and processed in 
different ways, depending on the source. Most sources involve the 
capture of byproduct gas mixture, purification of the gas, and final 
processing for the market as either liquified gas or as ``dry ice'' 
(solid carbon dioxide). Liquified

[[Page 13784]]

carbon dioxide gas is stored in pressurized refrigeration units or in 
tanks. Large quantities can be delivered as tanker trucks while small 
quantities can be obtained in 20-50-pound tanks from distributors. Dry 
ice is sold as ice blocks or pellets and shipped in insulated boxes.
NOSB Recommendation for Sec.  205.601(a)
    In 2022, the NOSB recommended adding synthetic carbon dioxide to 
the National List at 7 CFR 205.601(a) for water pH adjustment in 
irrigation systems.\2\ In addition to reviewing the petition, the Board 
considered a third-party technical report related to synthetic carbon 
dioxide used in organic handling and public comments received at public 
NOSB meetings in October 2021, April 2022, and October 
2022.3 4 5 6 The Board ultimately determined that the 
petitioned use of carbon dioxide meets the OFPA criteria (7 U.S.C. 
6518(m)) for inclusion on the National List.

---------------------------------------------------------------------------

    In its recommendation, the NOSB reasoned that when reclaimed 
synthetic carbon dioxide is used as petitioned, it is not harmful to 
the environment or human health. The Board acknowledged that carbon 
dioxide is a greenhouse gas; \7\ however, the use of synthetic carbon 
dioxide as petitioned would not increase carbon dioxide in the 
atmosphere. The petitioned form of synthetic carbon dioxide is a 
byproduct and, if not captured, would be released into the atmosphere. 
Therefore, the Board concluded that the capture of the byproduct for 
crop production is akin to recycling.
---------------------------------------------------------------------------

    \7\ Gases that trap heat in the atmosphere are called greenhouse 
gases. Overview of Greenhouse Gases, U.S. Environmental Protection 
Agency (EPA), www.epa.gov/ghgemissions/overview-greenhouse-gases.
---------------------------------------------------------------------------

    The NOSB also noted there are no apparent adverse effects on other 
materials used in organic farming systems and that carbon dioxide has 
little direct impact on human health. Additionally, carbon dioxide is 
already permitted on the National List for use in or on processed 
organic products (7 CFR 205.605(b)), which indicates its acceptance as 
not harmful to human health.
    The NOSB evaluated the suitability of natural alternatives and 
determined that natural sources of carbon dioxide are not widely 
available due to a lack of infrastructure at ethanol manufacturing 
facilities, where natural sources are produced. The Board acknowledged 
that some organic farmers have been using sulfurous acid from sulfur 
burners (Sec.  205.601(j)(11)) to lower pH levels in irrigation water. 
Sulfur burners create sulfurous acid by dissolving the fumes of burning 
sulfur in irrigation water, which can irritate human skin, eyes, and 
respiratory systems. The Board also considered that carbon dioxide is 
safer and more stable than alternatives, because using a weak acid such 
as carbon dioxide in the acidification process does not bring the pH of 
water below 5.0, well above values considered hazardous to humans.
    Overall, the NOSB determined that the use of synthetic carbon 
dioxide to adjust the pH of irrigation water would pose little risk to 
the environment or human health and is compatible with a system of 
sustainable agriculture. The Board's vote was unanimous in recommending 
the addition of carbon dioxide to Sec.  205.601(a) for use in 
irrigation systems.
NOSB Recommendation for Sec.  205.601(j)
    In 2024, the NOSB submitted a second recommendation to AMS related 
to the petition's request to add synthetic carbon dioxide to the 
National List in Sec.  205.601(j) for use as a crop or soil 
amendment.\8\ The petition did not detail the intended use(s), so the 
NOSB's Crops Subcommittee requested a new technical report.\9\ The 
technical report identified the most prevalent use of carbon dioxide as 
an atmospheric enrichment substance in indoor (e.g., greenhouse) crop 
production.

---------------------------------------------------------------------------

    The NOSB considered the petition, technical report, and public 
comments received at its public meetings in April 2024 and October 
2024.10 11 The Board ultimately determined that synthetic 
carbon dioxide, when sourced as a byproduct and used for atmospheric 
adjustment in indoor crop production, meets the OFPA criteria (7 U.S.C. 
6518(m)) for inclusion in the National List.

---------------------------------------------------------------------------

    In its recommendation, the NOSB explained the necessity of carbon 
dioxide supplementation in indoor crop production. An optimal 
concentration of atmospheric carbon dioxide for plant growth in a 
greenhouse environment is 800-1,000 parts per million. Plants consume 
atmospheric carbon dioxide as they grow, depleting carbon dioxide from 
the atmosphere inside the greenhouse. Supplemental carbon dioxide 
sources can be used to replenish the depleted atmospheric carbon 
dioxide within the greenhouse.
    The NOSB discussed alternative practices for adjusting atmospheric 
carbon dioxide, such as venting (exchanging air between inside and 
outside the greenhouse); however, venting is not a practical solution 
in colder climates due to the need for a controlled environment and 
consistent temperature for crop production.
    The NOSB evaluated the commercial sources of synthetic carbon 
dioxide and recommended allowing synthetic carbon dioxide only when 
sourced as a byproduct. The recommendation noted that synthetic carbon 
dioxide is available as a byproduct of manufacturing processes and 
propane heaters in greenhouses. The recommendation also noted that all 
commercial sources of synthetic carbon dioxide on the market are 
byproducts of other manufacturing processes. Restricting synthetic 
carbon dioxide to byproduct (recycled) sources only would ensure that 
the use of carbon dioxide will not have adverse effects on the 
environment. The Board also reaffirmed its assessment that natural 
sources are inadequate to meet commercial needs.
AMS Review of NOSB Recommendations
    AMS agrees with both NOSB recommendations to add synthetic carbon 
dioxide to 7 CFR 205.601(a) and 205.601(j), as these uses meet the 
requirements for adding a synthetic substance to the National List 
under OFPA at 7 U.S.C. 6517(c)(1)(A). AMS reviewed all documentation 
that the Board considered as part of their recommendations, including 
the petition and public comments.
    AMS agrees with the NOSB's conclusion that the recommended uses of 
carbon dioxide in crop production are not harmful to human health or 
the environment. This assessment is consistent with prior AMS 
determinations that supported the listing of synthetic carbon dioxide 
on the National List in 7 CFR 205.605(b) for

[[Page 13785]]

use in organic processing. Additionally, carbon dioxide is generally 
recognized as safe by the U.S. Food and Drug Administration (FDA) and 
permitted for direct addition to food for human consumption (21 CFR 
184.1240). The U.S. Environmental Protection Agency (EPA) also allows 
carbon dioxide for pest control on food commodities in storage (40 CFR 
180.1049), and as an inert ingredient in EPA-registered pesticides (40 
CFR 180.910) and minimum risk pesticide products (40 CFR 152.25(f)(2)). 
The EPA allowance for these uses is based on its assessment that the 
substance is not hazardous to public health or the environment.
    AMS also agrees with the NOSB's conclusions that allowed natural 
and synthetic alternatives to the specific petitioned uses of synthetic 
carbon dioxide are not commercially available. AMS invites additional 
comments on the necessity of synthetic carbon dioxide for the uses 
described in this proposed rule, including whether synthetic substances 
already on the National List or natural substances are suitable 
alternatives.
    If finalized, this proposed rule would add two listings for 
synthetic carbon dioxide to the National List for use in organic crop 
production. First, the rule proposes adding carbon dioxide to 7 CFR 
205.601(a), allowing organic crop producers to use synthetic carbon 
dioxide as an algicide, disinfectants, and sanitizer, including 
irrigation system cleaning. This listing would allow carbon dioxide to 
be used to adjust irrigation water pH to inhibit mineral and algae 
buildup, preventing the clogging of irrigation system equipment. 
Second, the rule proposes adding carbon dioxide, when sourced as a 
byproduct, to Sec.  205.601(j), allowing organic crop producers to use 
synthetic carbon dioxide as a crop or soil amendment. This listing 
would allow carbon dioxide to be used to adjust the atmosphere in 
indoor crop production systems, such as greenhouses. This listing also 
would allow carbon dioxide to be used to adjust irrigation water pH to 
establish ideal pH values for crop nutrient availability and protect 
soil quality from alkaline irrigation water.
    This proposed rule would not supersede or conflict with applicable 
FDA or EPA legal authority regarding the uses of carbon dioxide for 
irrigation water treatment or greenhouse atmospheric enrichment. For 
example, producers using substances to treat irrigation water would 
need to do so in a manner that complies with relevant provisions of the 
FDA Produce Safety rules for agricultural water (21 CFR part 112, 
subpart E).
    AMS requests comments about whether the proposed listing in 7 CFR 
205.601(a) should include the same annotation limiting the sources of 
carbon dioxide proposed in Sec.  205.601(j). Adding the annotation, 
``must be sourced as a byproduct,'' at Sec.  205.601(a), in addition to 
Sec.  205.601(j), would support consistency among the listings. AMS 
welcomes comments on whether adding the restriction, ``must be sourced 
as a byproduct,'' to Sec.  205.601(a) would preclude the intended uses 
of carbon dioxide as described in the petition and recommended by the 
Board. AMS also welcomes comments on whether any annotation related to 
the source of carbon dioxide is necessary for either listing.

B. Sodium Nitrate (Crops)

    This rule proposes renewing the listing for sodium nitrate on the 
National List at 7 CFR 205.602 as a natural substance allowed for 
limited use in organic crop production. This AMS proposal follows a 
recommendation from the NOSB in October 2021 to reinstate the listing 
for this substance. The listing for sodium nitrate is currently expired 
for reasons further described in Background below. If finalized, this 
proposed rule would allow for application of natural sodium nitrate as 
a nitrogen fertilizer for up to 20 percent of a crop's total nitrogen 
requirement,\12\ the same as prior to October 21, 2012, when the 
listing for sodium nitrate expired.
---------------------------------------------------------------------------

    \12\ For example, if a producer determines that their corn crop 
requires 120 pounds of nitrogen per acre, they may apply up to 20 
percent, or 24 pounds, of nitrogen from sodium nitrate. A typical 
sodium nitrate fertilizer contains 16% nitrogen, so a producer could 
apply such a fertilizer at a maximum rate of 150 pounds per acre to 
supply 24 pounds of nitrogen per acre to comply with the annotation.
---------------------------------------------------------------------------

Background
    The OFPA ``sunset provision'' requires that the NOSB reviews, and 
that AMS renews, each exception (``listing'') on the National List 
every 5 years (7 U.S.C. 6517(e)) for the listing to remain valid. This 
recurring re-review process is referred to as ``sunset review.'' For 
each substance on the National List, AMS calculates a ``sunset date'' 
that establishes the last date a substance listing is valid, calculated 
as 5 years after the date that AMS last renewed the listing. AMS 
publishes a complete list of sunset dates on its website.\13\
---------------------------------------------------------------------------

    \13\ Sunset dates for substances on the National List are 
included in the ``NOSB Work Agenda,'' accessible online at: 
www.ams.usda.gov/rules-regulations/organic/nosb.
---------------------------------------------------------------------------

    Typically, as the sunset date for a substance approaches, AMS 
either announces in the Federal Register that a substance on the 
National List is renewed (i.e., retained on the National List for 
another 5 years) or AMS proposes a rule to remove a substance from the 
National List. The removal of a substance is only complete if AMS 
publishes a final rule that follows such a proposal, as rulemaking is 
required to add, remove, or revise listings on the National List.
    A substance listing can expire (i.e., become invalid) if AMS does 
not complete rulemaking actions to either renew or remove a substance 
from the National List by the sunset date. This is the case with sodium 
nitrate. Sodium nitrate still appears on the National List at 7 CFR 
205.602, but AMS has not renewed its listing through rulemaking since 
October 21, 2007 (72 FR 58469, October 16, 2007). As announced in 2012, 
AMS considered possible regulatory action on sodium nitrate, (77 FR 
1996, January 12, 2012; 77 FR 33290, June 06, 2012), by either renewing 
the listing or by prohibiting sodium nitrate--both recommended by the 
NOSB in April 2011.\14\ However, AMS did not complete rulemaking. 
Therefore, the listing has expired.
---------------------------------------------------------------------------

    \14\ NOSB recommendation on sodium nitrate, April 2011, https://www.ams.usda.gov/sites/default/files/media/Sodium%20Nitrate%20Final%20Rec.pdf.
---------------------------------------------------------------------------

    The fact that the expired listing of sodium nitrate continues to 
appear on the National List creates confusion that this proposed rule 
seeks to remedy. If finalized, this rule would renew the listing and 
establish a new sunset date of 5 years after the effective date of a 
final rule. The proposed rule would retain the same limitations for use 
of sodium nitrate that were in place prior to the October 21, 2012 
sunset date and described at Sec.  205.602. Specifically, this proposed 
rule retains the maximum use rate for sodium nitrate of 20 percent of a 
crop's total nitrogen requirement.
    Finally, this proposal would remove obsolete language in the 
annotation stating that use of sodium nitrate in spirulina production 
is unrestricted until October 21, 2005. Spirulina producers were 
restricted in their use of sodium nitrate from October 21, 2005, until 
October 21, 2012. AMS has no information that spirulina production 
requires a different limit than other types of crop production.
NOSB Recommendation
    In October 2021, the NOSB unanimously recommended that AMS renew 
the listing for sodium nitrate on

[[Page 13786]]

the National List.\15\ In its recommendation, the Board explained that 
reinstatement was necessary to resolve the confusion with this listing 
and to create uniform enforcement among certifying agents. The Board 
also reasoned that a reinstatement was necessary to resume sunset 
reviews, as directed by OFPA.
---------------------------------------------------------------------------

    \15\ NOSB recommendation on sodium nitrate, October 2021, 
www.ams.usda.gov/sites/default/files/media/CSSodiumNitrateFinalRec.pdf.
---------------------------------------------------------------------------

    The NOSB evaluated over 60 public comments submitted at the October 
2021 public meeting on this topic.4 Most organic crop producers and 
certifying agents supported the reinstatement of sodium nitrate, as the 
action would provide clarity. Several certifying agents explained that 
they would have no issues verifying compliance with the restriction, as 
verification using crop nitrogen calculations was a common practice 
prior to 2012 when the listing was valid. One certifying agent stated 
that restricting the allowable amount is unnecessary because operations 
are using sodium nitrate at rates well below the limit of 20 percent of 
a crop's total nitrogen requirement. Some comments stated they would 
prefer a complete prohibition of sodium nitrate out of concern that 
highly soluble nitrogen sources like sodium nitrate only feed the plant 
and do not protect soil quality. The Board weighed all comments and 
finalized their unanimous recommendation for AMS to reinstate the 
listing of sodium nitrate on the National List and allow its use for up 
to 20 percent of a crop's total nitrogen requirement, which protects 
soil quality.
AMS Review of NOSB Recommendation
    AMS agrees with the NOSB's recommendation to reinstate the listing 
of sodium nitrate on the National List. The fact that sodium nitrate 
appears on the National List as an expired listing creates confusion. 
This proposed rule would resolve this confusion by affirming that the 
use of sodium nitrate as annotated (i.e., comprising less than 20 
percent of the crops' nitrogen requirements) is valid for 5 years from 
the effective date of a final rule. The proposed action, if finalized, 
would then allow the Board to subsequently review sodium nitrate 
according to the OFPA sunset provision (7 U.S.C. 6517(e)). The proposed 
rule would also implement a technical correction to remove obsolete 
language exempting spirulina production from the use limits that 
expired on October 21, 2005.
    AMS also considered resolving the expired listing by removing 
sodium nitrate from the National List. However, OFPA requires a 
recommendation from the NOSB to revise the National List (7 U.S.C. 
6517(c)(1)(C) and 6517(d)(1)), and the Board has made no such 
recommendation. Therefore, AMS believes this proposed action to 
reinstate the listing is the simplest and most effective approach to 
resolve the confusion around the sodium nitrate listing. If finalized, 
the rule would provide a path forward for the Board and AMS to resume a 
regular sunset review schedule for the sodium nitrate listing, like all 
other substances on the National List.

C. Meloxicam (Livestock)

    AMS is proposing to add meloxicam to the National List at 7 CFR 
205.603(a) as a synthetic substance allowed for use in organic 
livestock production. Meloxicam is a nonsteroidal anti-inflammatory 
drug (NSAID) used primarily to treat pain and inflammation. Organic 
livestock producers petitioned for use of meloxicam because they 
identified a need in their industry for more tools to improve pain 
management in their operations, for both dairy and meat animals. This 
AMS proposal follows a recommendation from the NOSB after their review 
of the petition as well as public comment.
Background
    On February 6, 2024, a group of organic dairy operations submitted 
a petition to the NOSB to allow synthetic meloxicam as a medical 
treatment in organic livestock production at 7 CFR 205.603(a).\16\ 
Meloxicam is an NSAID that works by reducing hormones that cause pain 
and inflammation in the body. Nonorganic dairy operations often use it 
as an easy and effective treatment of pain related to common veterinary 
procedures, such as disbudding (the removal of the soft tissue that 
would otherwise form horns on livestock) and dehorning. It is also used 
to manage pain related to castration and other surgical procedures and 
medical conditions. Meloxicam is typically administered to livestock in 
oral tablet form, though it is also available as an injection. Its 
therapeutic effect lasts 24-48 hours with a single dose.

Organic Dairy petition, February 06, 2024, www.ams.usda.gov/sites/default/files/media/NOPPetitionMeloxicamV2.pdf.
---------------------------------------------------------------------------

    While other pain management substances are available for organic 
livestock producers to use, petitioners explained that they are 
difficult to administer. The petition argues that meloxicam is easier 
to administer and/or more effective. For example, flunixin can only be 
administered by intravenous injection or by transdermal (i.e., pour-on) 
solution. Using intravenous flunixin requires the producer to have the 
technical skills necessary to administer the injection. Administering 
transdermal flunixin requires caution to avoid spills or accidental 
human absorption while pouring the medicine on the animal. Neither 
application method of flunixin, the petition argues, is as easy nor as 
safe as the orally administered meloxicam pill. The petition also 
describes other alternatives as being less effective than meloxicam, 
e.g., lidocaine has shorter-lived therapeutic effects, and natural 
remedies or tinctures show inconsistent effects in scientific studies.
FDA Allowance
    Meloxicam is FDA-approved for use in humans and in certain 
companion animals (per approved labeling for dogs and/or cats) but only 
authorized for use in food-producing livestock under the conditions 
established by FDA at 21 CFR part 530. This practice, called extralabel 
use, was established by the Animal Medicinal Drug Use Clarification Act 
of 1994 (AMDUCA).\17\ Extralabel use is when a drug is used in a manner 
that is not in accordance with the approved labeling (21 CFR 530.3).

---------------------------------------------------------------------------

    FDA regulations at 21 CFR part 530 establish the conditions under 
which a licensed veterinarian may prescribe the extralabel use of FDA-
approved drugs for treatment of meat- or dairy-producing animals. FDA 
regulations require veterinarians to use scientific information to 
establish an appropriate withdrawal period, i.e., the required time 
between administering the treatment and the marketing of milk, meat, or 
other edible products from the animal (21 CFR 530.20(a)(2)(ii)). The 
withdrawal period must assure that no drug residues that could present 
a risk to public health remain in the animal (21 CFR 530.20(a)(2)(iv); 
21 CFR 530.11).

NOSB Recommendation
    In October 2024, the NOSB recommended adding meloxicam to 7 CFR 
205.603(a) for use in organic livestock production.\19\ The Board 
concluded that meloxicam is a synthetic substance and that the 
petitioned use of meloxicam meets the OFPA criteria for allowing a 
synthetic substance in organic production (7 U.S.C. 6517-6518). The 
Board voted in favor of adding meloxicam to the National List.
---------------------------------------------------------------------------

    \19\ NOSB recommendation on meloxicam, October 2024, 
www.ams.usda.gov/sites/default/files/media/LS_MeloxicamFinalRec.pdf.
---------------------------------------------------------------------------

    The NOSB's recommendation involved a thorough evaluation of the 
petition and public comments received during its October 2024 meeting. 
The petition included substantial technical information and numerous 
appendices with scientific literature to support the Board's review. 
Comments were provided from a range of stakeholders including farmers, 
manufacturers, veterinarians, researchers, trade associations, advocacy 
groups, certifying agents, inspectors, and consumers. There were more 
than 40 substantive written and oral comments provided to the Board 
specific to meloxicam, the majority of which supported the NOSB 
recommendation to allow meloxicam in organic production.
    In the recommendation, the NOSB noted that the use of meloxicam has 
minimal adverse effects on the environment or human health (7 U.S.C. 
6517(c)(1)(A)(i); 7 U.S.C. 6518(m)(1)-(5)). Specifically, the Board 
described that after the drug is administered to livestock, it is 
metabolized into biologically inactive metabolites, which have no 
adverse impacts on soil organisms or biodiversity when excreted from 
livestock through feces and urine. Several licensed veterinarians and 
university research centers submitted comments to the Board stating 
that meloxicam has been legally and safely administered to livestock 
with no observed negative side effects. Regarding human health, the FDA 
approved meloxicam for human use by prescription, and it is considered 
safe when taken according to the physician's recommendation. As noted 
above, FDA regulations at 21 CFR part 530 require that the 
administration of meloxicam to livestock is followed by a sufficient 
withdrawal period to ensure no residues enter the human food supply 
that would present a risk to public health.
    The NOSB thoroughly discussed and evaluated the process that 
licensed veterinarians use to comply with AMDUCA and its implementing 
regulations at 21 CFR part 530. This included evaluating the veterinary 
procedures for diagnosing a specific condition or illness and obtaining 
scientific information to determine withdrawal periods for the specific 
dose, duration, and other confounding factors. The Board also received 
feedback from organic certifying agents, inspectors, and certified 
producers about the procedures currently in place for documenting 
treatments and verifying compliance with withdrawal times. The Board 
recommended that the withdrawal period for meloxicam in organic 
livestock should be double that required by the FDA for compliance with 
AMDUCA.
    NOSB evaluated alternatives and determined that meloxicam is 
necessary for organic livestock production (7 U.S.C. 6517(c)(1)(A)(ii); 
7 U.S.C. 6518(m)(6)). The Board recognized that the petition was 
submitted by a varied cross-section of the organic dairy industry 
representing a majority of U.S. organic dairy operations. Information 
in the petition and provided by public comments from livestock 
operators indicate a need for safe and effective pain management tools 
in both organic meat- and milk-producing animals. Specifically, the 
Board cited that meloxicam is easier to administer, provides longer 
therapeutic effectiveness, and requires fewer treatments in a specified 
period compared to alternatives.
    The NOSB determined that alternative NSAIDs are insufficient 
replacements for meloxicam. Flunixin, whether in an injectable or pour-
on form, is more difficult to apply than meloxicam, which can be 
administered by an oral tablet. Aspirin is another NSAID currently on 
the National List for use in livestock, but the FDA clarified that 
aspirin products are not permitted for use in lactating dairy 
cattle.\20\ Lidocaine is on the National List for use in livestock as a 
local numbing relief, typically during disbudding, but its efficacy 
duration is far shorter that meloxicam (less than 2 hours for lidocaine 
compared to 24-48 hours for meloxicam). According to the Board's review 
of studies submitted with the petition and public comments, natural 
alternatives such as herbal tinctures or willow bark are not effective 
in managing pain.

products in lactating dairy cattle. October 11, 2024, www.fda.gov/animal-veterinary/product-safety-information/dear-veterinarian-letter-regarding-use-aspirin-products-lactating-dairy-cattle.
---------------------------------------------------------------------------

    The NOSB determined that the petitioned use of meloxicam is 
consistent with organic farming and compatible with sustainable 
agriculture (7 U.S.C. 6517(c)(1)(A)(iii); 7 U.S.C. 6518(m)(7)). The 
Board noted that safe and effective pain management is important for 
protecting animal welfare. The Board received comments from animal 
welfare groups supporting the allowance of meloxicam for organic 
livestock.
    The NOSB explained that organic producers need access to 
appropriate pain management tools for dairy- and meat-producing 
livestock of all species and stages of life. A few comments suggested 
that meloxicam should be limited to disbudding bovine calves younger 
than 1 year of age. Other comments from producers and veterinarians 
cited the benefits of meloxicam as a pain relief tool for older 
animals, for non-bovine animals, and for treatments of pain other than 
disbudding, such as castration. The NOSB recommendation states that all 
animals need to receive pain management in accordance with veterinarian 
recommendations.
    Board members on the NOSB's Livestock Subcommittee 
(``Subcommittee'') used their expertise in livestock management and 
relevant disciplines to evaluate technical information during their 
consideration of the meloxicam petition. The Subcommittee determined 
that the technical information provided in the petition was thorough, 
objective, and sufficient to evaluate meloxicam in conjunction with the 
Subcommittee members' own technical expertise and information-gathering 
effort. To verify sufficiency of the petition's technical information, 
the Subcommittee produced a technical appendix document that references 
how each question typically covered in a third-party technical report 
is directly addressed in the petition. The technical appendix document 
is attached to the Board's final recommendation, available on the AMS 
website, but was not published with the Subcommittee's original 
proposal prior to its meeting.\21\

begins on page 8 of the final recommendation: www.ams.usda.gov/sites/default/files/media/LS_MeloxicamFinalRec.pdf.
---------------------------------------------------------------------------

    During the NOSB deliberation at the public meeting, some Board 
members stated they would have preferred the Subcommittee to publish 
its technical analysis appendix for public visibility prior to the 
meeting. Some commenters

[[Page 13788]]

also said that more technical information was needed and requested the 
issue be returned to the Subcommittee for further study. With support 
from the majority of commenters, the Board determined that there was 
sufficient technical information to support their recommendation, 
citing the robustness of the petition and public comments (including 
technical expertise of veterinarians and producers who authored the 
petition and submitted comments), in combination with the 
Subcommittee's own expertise in livestock production. Ultimately, the 
Board voted in favor of the recommendation. The Subcommittee's 
technical analysis appendix is publicly available on the AMS website as 
part of the NOSB final recommendation, and AMS welcomes comments from 
the public during this comment period.
AMS Review of NOSB Recommendation
    AMS agrees with the NOSB recommendation to allow meloxicam as a 
medical treatment for organic livestock, as meloxicam meets the 
requirements for adding a substance to the National List under 7 U.S.C. 
6517(c)(1)(A). AMS reviewed all documentation that the Board considered 
as part of its recommendation, including the petition and public 
comments, and consulted with the FDA to inform this determination. AMS 
also agrees with the Board's recommendation to classify meloxicam as 
synthetic because it is manufactured through a process that meets the 
definition of ``synthetic'' at 7 CFR 205.2.
    AMS has reviewed and agrees with the NOSB's conclusion that the 
petitioned use of meloxicam is not harmful to human health or the 
environment (7 U.S.C. 6517(c)(1)(A)(i)). The FDA regulations that 
implement AMDUCA (21 CFR part 530) are sufficient to ensure that 
meloxicam is used in a manner that does not pose harm to human health. 
Scientific information reviewed by the Board and AMS indicates that 
metabolites of meloxicam excreted by livestock do not pose harm to the 
environment.
    Consistent with the NOSB's recommendation, AMS proposes that the 
withdrawal period for meloxicam would be calculated to be twice as long 
as what a licensed veterinarian determines to be required for 
compliance with FDA regulations (AMDUCA (21 CFR 530.20(a)(2)(ii))). For 
example, if a licensed veterinarian determines that a 5-day milk 
withdrawal period is appropriate for extralabel use of meloxicam under 
full compliance with AMDUCA, then the withdrawal time would be doubled 
to 10 days for compliance with the USDA organic regulations for use in 
organic livestock.
    AMS understands that veterinarians determine withdrawal periods for 
each animal based on the individual animal's conditions, diagnosis, 
dosage, and other case-specific factors in full compliance with AMDUCA. 
This approach may result in some variation in withdrawal times between 
animals with different conditions. However, it is an approach that 
relies on well-established FDA legal oversight of the use of animal 
drugs and the sound expertise of licensed veterinarians to determine 
appropriate prescriptions of each treated animal.
    The extended withdrawal period proposed in this rule is only 
relevant for use of the substance under USDA organic regulations. 
Organic livestock producers are prohibited from administering animal 
drugs in violation of the Federal Food, Drug, and Cosmetic Act (7 CFR 
205.238(c)(6)). This proposed rule would not supersede or conflict with 
the FDA's authority to approve drugs and determine the withdrawal 
periods for animal drugs.
    AMS agrees with the NOSB determination that the use of meloxicam is 
necessary to the production or handling of the agricultural product 
because of the unavailability of natural substitutes (7 U.S.C. 
6517(c)(1)(A)(ii)). Meloxicam is easy to administer as an oral pill 
compared to alternatives that require an intravenous or transdermal 
(pour-on) application. Meloxicam also has longer efficacy duration and 
requires fewer treatments in a given period than any alternatives. The 
majority of public comments and the Board vote indicate a broad range 
of support across the organic industry for the allowance of meloxicam 
in organic livestock production.
    AMS further agrees with the NOSB determination that the use of 
meloxicam is consistent with organic farming (7 U.S.C. 
6517(c)(1)(A)(iii)). USDA organic regulations require producers to 
establish and maintain preventive health care practices. Physical 
alterations and surgical procedures must be performed in a manner that 
minimizes pain, stress, and suffering, and with the use of allowed 
anesthetics, analgesics, and sedatives, as appropriate (7 CFR 
205.238(a)(5) and 205.238(a)(7)). USDA organic regulations provide for 
the allowance of medications to alleviate pain or suffering and when 
preventive practices are inadequate to prevent sickness (7 CFR 
205.238(b)). The use of meloxicam for pain management is consistent 
with the USDA organic regulations for minimizing pain and stress in 
organic livestock.
    AMS finds that meloxicam meets OFPA requirements and proposes 
adding it to the National List at Sec.  205.603(a) as a synthetic 
substance allowed in organic livestock production. If this proposal is 
finalized, meloxicam would be allowed for use as a medical treatment in 
organic livestock production. The proposed listing would require that 
meloxicam be used in full compliance with AMDUCA and 21 CFR part 530 of 
the FDA regulations. The proposed annotation further requires that 
meloxicam may only be used in organic production by the lawful written 
order of a licensed veterinarian, and the withdrawal period must be at 
least twice that required by FDA. Excipients added to product 
formulations would need to comply with 7 CFR 205.603(f).\22\
---------------------------------------------------------------------------

    \22\ Excipients are ingredients that are intentionally added to 
livestock medications but do not exert therapeutic or diagnostic 
effects at the intended dosage, although they may act to improve 
product delivery (7 CFR 205.2).
---------------------------------------------------------------------------

    To comply with the proposed withdrawal period, AMS expects that 
veterinarians, organic livestock operations, and certifying agents 
would follow the same process for determining, documenting, and 
verifying compliance of withdrawal periods for meloxicam as is done for 
other synthetic substances on the National List that are used in 
accordance with AMDUCA. The proposed annotation to double the FDA 
withdrawal period is consistent with other synthetic livestock 
medications on the National List for which the FDA-required withdrawal 
period is doubled (e.g., flunixin).
    AMS welcomes comments on whether the proposed annotation is clear 
enough to allow producers to comply with the proposed requirements. If 
elements of the annotation are unclear, AMS welcomes suggestions for 
language to clarify the annotation to achieve the intended outcomes 
described in this proposed rule.
    In developing this proposed rule, AMS considered alternative 
annotation language that would further restrict the use of meloxicam. 
For instance, AMS considered proposing a specific minimum withdrawal 
time for bovine species (i.e., cattle and calves). The minimum 
withdrawal period could, for example, be calculated by doubling the 
longest recommended withdrawal times indicated by public comments: a 
meat withdrawal period of at least 56 days after administering to 
bovine livestock intended for slaughter, and a milk

[[Page 13789]]

discard period of at least 10 days after administering to bovine dairy 
animals. AMS welcomes comments on whether a specified minimum 
withdrawal period is necessary, and if so, what specific duration is 
appropriate for meat- and milk-producing bovine species. AMS also 
welcomes comments on whether further restrictions are appropriate, such 
as whether meloxicam should only be allowed for treating pain resulting 
from disbudding and dehorning, or whether meloxicam should be limited 
to certain species (e.g., allowed for cattle but not allowed for goats 
and sheep).

D. Methionine (Livestock)

    This rule proposes amending the current allowance of methionine, an 
amino acid, in poultry diets by removing the limits on the amount of 
synthetic methionine a producer can add to poultry feed rations. This 
AMS proposal follows a unanimous recommendation from the NOSB. If 
finalized, producers will have greater flexibility in using methionine 
to meet the health and nutrition requirements of organic poultry 
flocks.
Background
    Methionine is an essential amino acid for poultry. It is a critical 
building block for proteins that form muscles, tissues, feathers, and 
support immune response. Without sufficient methionine, poultry are at 
risk of several significant health and production issues, including 
growth impairment, compromised immune function, poor feathering, 
reduced egg production, and behavioral problems like nervousness, 
feather picking, and cannibalism.
    Poultry cannot synthesize methionine on their own, so they must 
obtain it from protein sources in their diets. Common plant-based 
feedstuffs typically lack a sufficient supply of methionine. Therefore, 
synthetic methionine is commonly added to poultry feed rations to meet 
nutritional needs of poultry.
    The USDA organic regulations have allowed synthetic methionine for 
organic livestock production since 2003 (68 FR 61987, October 31, 
2003). Methionine has undergone several amendments on the National List 
to restrict its use in various ways, including the use of expiration 
dates and maximum use limits. The current restriction, which has been 
effective since 2019, limits its use to no more than 2 to 3 pounds of 
methionine per ton of feed, depending on the type and species of 
poultry, calculated as an average over the life of the flock.\23\ In 
this rulemaking, AMS is proposing to remove these limits and to allow 
the use of methionine as an organic poultry feed additive without 
restriction beyond the existing general practice standards for 
livestock feed in Sec.  205.237.
---------------------------------------------------------------------------

    \23\ The full text of the current annotation is, ``for use only 
in organic poultry production at the following pounds of synthetic 
100 percent methionine per ton of feed in the diet, maximum rates as 
averaged per ton of feed over the life of the flock: Laying 
chickens--2 pounds; broiler chickens--2.5 pounds; turkeys and all 
other poultry--3 pounds.'' 7 CFR 205.603(d)(1).
---------------------------------------------------------------------------

NOSB Recommendation
    In October 2024, the NOSB unanimously recommended amending the 
National List to remove the limit on the amount of methionine that 
organic producers may feed to poultry.\24\ The Board recommended 
removing this limit primarily to give organic producers more 
flexibility to use methionine to support bird health and to reduce 
overly burdensome recordkeeping requirements.
---------------------------------------------------------------------------

    \24\ NOSB recommendation on methionine, October 2024, 
www.ams.usda.gov/sites/default/files/media/LS_DLMethionineAnnotChangeFinalRec.pdf.
---------------------------------------------------------------------------

    In the rationale supporting its recommendation, the NOSB noted the 
challenges caused by the current annotation. The current limits have 
prevented some producers from being able to feed their poultry adequate 
methionine. To address this deficiency, some producers increased the 
amount of feed ingredients that are high in methionine, like soybean 
meal. However, these dietary adjustments (e.g., feeding more soybean 
meal to address methionine deficits) can increase crude protein levels, 
which can negatively affect bird health, create problems with manure 
management, and result in increased ammonia concentration in poultry 
housing. To give producers more flexibility to provide healthy balanced 
feed rations, without resorting to over-feeding protein and creating 
secondary problems, the Board recommended removing the limit on 
methionine.
    The NOSB recommendation also noted the ongoing lack of natural 
alternatives to synthetic methionine. One of the historical 
justifications for limiting synthetic methionine was preserving the 
incentive to develop viable natural methionine alternatives. Over the 
years, the organic industry has explored a number of possible sources 
of natural methionine, such as insects and fermentation products. 
However, these products have not achieved widespread adoption or 
developed the production scale necessary to adequately address the 
needs of the organic poultry industry. Because the limit on synthetic 
methionine has not meaningfully accelerated a natural alternative, the 
Board reasoned that a limit is not effective for this purpose.
    The NOSB also explained its recommendation is intended to better 
align USDA organic regulations with those of our trading partners. For 
example, neither the European Union (EU) nor Canada limit the amount of 
methionine in organic feed. EU organic regulations permit a certain 
percentage of non-organic ingredients in grain-based poultry diets, 
which allows organic producers in the EU to include high-methionine 
ingredients (e.g., corn gluten meal) in poultry feed to meet birds' 
needs. Similarly, Canada permits the addition of synthetic methionine 
when naturally occurring sources are not adequate to meet a flock's 
needs.
    The NOSB recommendation was informed by public comments at the 
October 2024 meeting.\11\ The majority of comments were supportive of 
removing the limits on methionine, citing benefits such as reduced 
paperwork burden for producers, inspectors, and certifying agents, as 
well as better health outcomes for poultry flocks. Comments from 
organic poultry operations and organic certification agencies indicated 
the recordkeeping burden was especially difficult for small farms and 
farms with mixed flocks of multiple poultry species that each required 
separate calculations. Calculating lifetime averages can also be 
challenging for flocks that change ownership or locations, requiring a 
combination of records from multiple operations. Commenters also 
continued to note that no viable natural alternatives to methionine 
have been found.
AMS Review of NOSB Recommendation
    AMS agrees with the NOSB recommendation to allow methionine as an 
organic poultry feed additive without limits on the amount of 
methionine that may be added to organic poultry rations. This 
deregulatory action will give producers maximum flexibility in using 
methionine to meet the health and nutrition needs of their flocks. 
Furthermore, this proposed action will lift a recordkeeping burden from 
organic producers, who will no longer need to maintain records 
documenting pounds of methionine fed per ton of feed over the lifetime 
of each flock.
    AMS also agrees with the NOSB's determination that synthetic 
methionine continues to be necessary for organic poultry production due 
to the absence of natural alternatives. Although existing limits were 
intended to

[[Page 13790]]

incentivize the development of natural alternatives, it does not appear 
that the limits have been effective for this purpose. Viable natural 
alternatives have not been developed and are not commercially available 
to the extent necessary to support the organic poultry industry. 
Removing the limit on synthetic methionine should not deter future 
development of natural alternatives.
    AMS concludes that all criteria at 7 U.S.C. 6517(c)(1)(A) would 
continue to be met under this proposed rule, even in the absence of the 
current limits. This supports the inclusion of synthetic methionine on 
the National List. Synthetic methionine is not harmful to human health 
or the environment, is necessary to the organic poultry production 
because of the unavailability of wholly natural substitute products and 
is consistent with organic farming and handling practices.
    If this proposed amendment is finalized, producers will maintain 
access to synthetic methionine for use as a feed additive in organic 
poultry production. Producers would be allowed to use methionine in 
poultry feed in a way that complies with USDA organic regulations to 
meet the nutritional requirements of the animal (7 CFR 205.237 and 
205.238(a)(2)).

V. Regulatory Analyses

A. Executive Order (E.O.) 12866 and E.O. 13563

    USDA is issuing this proposed rule in conformance with Executive 
Orders (E.O.) 12866, ``Regulatory Planning and Review,'' and E.O. 
13563, ``Improving Regulation and Regulatory Review.'' This proposed 
rule has been determined to be not significant for purposes of 
Executive Order 12866, and, therefore, has not been reviewed by the 
Office of Management and Budget (OMB).

B. Regulatory Flexibility Act

    The Regulatory Flexibility Act (RFA) (5 U.S.C. 601-612) requires 
agencies to consider the economic impact of each rule on small entities 
and evaluate alternatives that would accomplish the objectives of the 
rule without unduly burdening small entities or erecting barriers that 
would restrict their ability to compete in the market. The purpose of 
the RFA is to fit regulatory actions to the scale of businesses subject 
to the action. Section 605 of the RFA allows an agency to certify a 
rule, in lieu of preparing an analysis, if the final rule is not 
expected to have a significant economic impact on a substantial number 
of small entities.
    AMS does not expect the economic impact on entities affected by 
this rulemaking to be significant. This proposed rule would allow two 
additional substances in organic crop and livestock production and 
would remove restrictions on the use of one substance, thus removing 
paperwork and regulatory burdens. The amendments would provide small 
entities with more options to use in day-to-day operations. The 
proposed rule would also affirm the validity of current USDA organic 
regulations related to the use of sodium nitrate as a nitrogen 
fertilizer. AMS does not expect any significant economic impact related 
to this action for small entities, as certified operations are already 
required to maintain records of all activities (e.g., input 
applications) and transactions.

C. E.O. 12988

    E.O. 12988 instructs each executive agency to adhere to certain 
requirements in the development of new and revised regulations to avoid 
unduly burdening the court system. This proposed rule is not intended 
to have a retroactive effect. Accordingly, to prevent duplicative 
regulation, states and local jurisdictions are preempted under OFPA 
from creating programs of accreditation for private persons or state 
officials who want to become certifying agents of organic farms or 
handling operations. A governing state official would have to apply to 
the USDA to be accredited as a certifying agent, as described in OFPA 
(7 U.S.C. 6514(b)). States are also preempted from creating 
certification programs to certify organic farms or handling operations 
unless the state programs have been submitted to, and approved by, the 
Secretary as meeting the requirements of OFPA (7 U.S.C. 6501-6524).
    Pursuant to OFPA (7 U.S.C. 6507(b)(2)), a state organic 
certification program that has been approved by the Secretary may, 
under certain circumstances, contain additional requirements for the 
production and handling of agricultural products organically produced 
in the state and for the certification of organic farm and handling 
operations located within the state. Such additional requirements must 
(a) further the purposes of OFPA, (b) not be inconsistent with OFPA, 
(c) not be discriminatory towards agricultural commodities organically 
produced in other states, and (d) not be effective until approved by 
the Secretary.
    In addition, pursuant to 7 U.S.C. 6519(c)(6) of the OFPA, this 
proposed rule does not supersede or alter the authority of the 
Secretary under the Federal Meat Inspection Act (21 U.S.C. 601-624), 
the Poultry Products Inspection Act (21 U.S.C. 451-471), or the Egg 
Products Inspection Act (21 U.S.C. 1031-1056) concerning meat, poultry, 
and egg products, respectively, nor any of the authorities of the 
Secretary of Health and Human Services under the Federal Food, Drug and 
Cosmetic Act (21 U.S.C. 301 et seq.), nor the authority of the 
Administrator of the EPA under the Federal Insecticide, Fungicide and 
Rodenticide Act (7 U.S.C. 136 et seq.).

D. Paperwork Reduction Act

    Routine collection, reporting and recordkeeping related to the use 
of substances on the National List are covered under OMB Number 0581-
0191. No additional collection or recordkeeping requirements are 
imposed on the public by this proposed rule. Accordingly, OMB clearance 
is not required by the Paperwork Reduction Act of 1995, 44 U.S.C. 3501, 
chapter 35.

E. E.O. 13175

    E.O. 13175 requires Federal agencies to consult and coordinate with 
Tribes on a government-to-government basis on policies that have Tribal 
implications, including regulations, legislative comments or proposed 
legislation, and other policy statements or actions that have 
substantial direct effects on one or more Indian Tribes, the 
relationship between the Federal Government and Indian Tribes, or on 
the distribution of power and responsibilities between the Federal 
Government and Indian Tribes. AMS has assessed the impact of this 
proposed rule on Indian Tribes and determined that this rulemaking 
would not have Tribal implications that require consultation under E.O. 
13175.

F. Unfunded Mandates Reform Act

    This proposed rule does not contain Federal mandates under the 
regulatory

[[Page 13791]]

provisions of title II of the Unfunded Mandates Reform Act of 1995 (2 
U.S.C. chapter 25) (UMRA) for State, local and Tribal governments, or 
the private sector of $100 million or more in any one year. Thus, the 
proposed rule is not subject to the requirements of sections 202 and 
205 of the UMRA.
