Bergeson & Campbell, P.C. serves small, medium, and large pesticide product registrants and other stakeholders in the agricultural and biocidal sectors, in virtually every aspect of pesticide law, policy, science, and regulation.

This week's All Things Chemical™ Podcast will be of interest to readers of the Pesticide Law & Policy Blog®. A brief description of the episode written by Lynn L. Bergeson is below.

This week I sat down with James Aidala, B&C’s Senior Government Affairs Consultant, to catch up on what the U.S. Environmental Protection Agency’s (EPA) Office of Pesticide Programs (OPP) is up to and to get a sense of what we might expect to develop over the remainder of the year.  As a former Assistant Administrator of what is now the Office of Chemical Safety and Pollution Prevention, Jim’s thoughts and analyses are always spot on.

We discuss leadership within OPP, which is transitioning.  Not surprisingly, who holds the position of Office Director is always of great interest to the agricultural and biocidal chemical communities.

We also touch upon a number of high-profile pesticide science policy debates about substances, some of which have been raging literally for years.  These substances include dicamba, glyphosate, and chlorpyrifos.  The legal and scientific administrative and judicial reviews under way in the United States and internationally are fascinating, precedent setting, and closely watched.

Our conversation also includes a bit about the commercial agricultural chemical community.  Industry consolidation and international trade issues continue to challenge the commercial landscape, and they make keeping up with these issues all the more important.

On July 6, 2020, the U.S. Environmental Protection Agency (EPA) announced that it approved amended labels for two products, Lysol Disinfectant Spray (EPA Reg. No. 777-99) and Lysol Disinfectant Max Cover Mist (EPA Reg. No. 777-127), based on laboratory testing that shows the products are effective against SARS-CoV-2.  These are the first products for which EPA has reviewed laboratory testing data and approved label claims against SARS-CoV-2. 

In January 2020, at the beginning of the SARS-CoV-2 public health emergency, EPA activated its Emerging Viral Pathogens guidance (Guidance),  This Guidance was developed in April 2016 to set forth procedures for EPA to respond to the potential need for products to combat emerging viral pathogens that are not on EPA-registered disinfectant labels.  The Guidance allows product registrants to make limited claims of their product’s efficacy against SARS-CoV-2, provided in part that there are efficacy data that have already been reviewed by EPA and demonstrate their products are effective against harder-to-kill viruses than SARS-CoV-2. 

Since activating its Guidance for the first time, EPA has reviewed amendments for already EPA-registered surface disinfectants on an expedited basis and developed a list -- List N -- of products that meet its criteria under the Guidance for use against SARS-CoV-2.  List N currently includes 431 products and is updated weekly.  In many cases, EPA states that it was able to approve claims in as little as 14 days.

This week, EPA updated the entries for the two Lysol products on List N to indicate they have now been tested directly against SARS-CoV-2.  This is significant since they are the first List N products for which EPA has reviewed laboratory testing data specifically against SARS-CoV-2, and not listed based on EPA’s determination that a product can be used against SARS-CoV-2 because of the product’s effectiveness against a harder-to-kill virus. 

EPA states that it expects to approve such claims for additional List N products in the coming weeks.

The U.S. Environmental Protection Agency (EPA) announced on July 2, 2020, that it has registered NSPW Nanosilver (a new nanosilver formulation) to suppress odor-causing bacteria and algae, fungus, mold, and mildew that can cause deterioration or staining in textiles.  Textiles that may be treated with NSPW Nanosilver include fabrics, sportswear, footwear, linens, and awnings.  NSPW Nanosilver is the active ingredient in the pesticide product POLYGUARD-NSPW MASTER BATCH (Polyguard).  The NSPW Nanosilver in Polyguard will be embedded within beads or pellets of a polymeric material in a “master batch,” and these beads of pellets will then be incorporated into treated textiles through a closed-loop manufacturing process.  EPA states that once the beads or pellets containing NSPW Nanosilver are introduced into this manufacturing process, no beads or pellets can escape into the environment.  EPA also states that the available data indicate that the leach rate of nanosilver from NSPW Nanosilver-treated textiles is below the limit of detection.

The same type of nanosilver was the active ingredient in another product that EPA previously conditionally registered under FIFRA Section 3(c)(7)(C) in 2015.  The U.S. Court of Appeals for the Ninth Circuit issued a decision vacating that conditional registration because the court concluded that the mandatory public interest finding by EPA was not adequately supported by the administrative record.  According to EPA, the new registration for NSPW Nanosilver involves a modified use pattern that will limit exposures compared to the product that received the previously vacated conditional registration.  Based on additional data that the applicant has submitted to support the use pattern as modified, EPA has prepared an updated risk assessment for NSPW Nanosilver and has determined based on that risk assessment that the product as modified meets the standard for an unconditional registration under FIFRA Section 3(c)(5).  Materials supporting this action will be posted in Docket ID EPA-HQ-OPP-2020-0043.

Commentary

Registering any new metallic silver product that satisfies the EPA criteria for classification as nanosilver for use as an antimicrobial pesticide presents special challenges, because EPA has adopted a policy that it will construe each new nanosilver product as a new pesticidal active ingredient.  The predecessor to NSPW Nanosilver (Nanosilva) was granted a conditional registration, a procedure that EPA uses when there are data gaps that must be filled before EPA is ready to make the determinations that would support issuance of an unconditional registration.  EPA may only issue a conditional registration for a product containing a new pesticidal active ingredient when EPA makes a determination that “use of the pesticide is in the public interest,” and the Ninth Circuit Court determined that EPA did not compile an administrative record adequate to support that finding.

Colloidal metallic silver products that meet the definition of nanosilver were first synthesized in the late 19th century.  Some industry stakeholders question whether the differences between different pesticide products that satisfy the EPA definition of nanosilver are sufficiently great to treat each new product as a new active ingredient, but it is also clear that the size and shape of the particles in these products do vary.  In this instance, EPA has determined that the supporting data for the application allow EPA to issue an unconditional registration.  Accordingly, the legal issue on which the Ninth Circuit based its prior decision to vacate the conditional registration for Nanosilva is not pertinent to the current registration decision.  Given the challenge to the prior registration decision, it will be important to monitor any opposition to the newly issued registration.

On June 8, 2020, the U.S. Environmental Protection Agency (EPA) announced the issuance of an existing stocks order under Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) Section 6(a)(1) governing further sale, distribution, and use of existing stocks of three reduced volatility dicamba products (XtendiMax®, EngeniaTM, and FeXapanTM) with conditional registrations that were vacated by the June 3, 2020, decision of the Ninth Circuit Court of Appeals in National Family Farm Coalition v. EPA.  EPA explained its action by stating that the existing stocks order would provide “clarity to farmers” in light of the Court decision.  Because EPA believes that vacatur made those stocks of the three dicamba products that were already in channels of trade unregistered pesticides, and the Court’s decision did not specifically address or establish any regimen to govern these unregistered existing stocks, EPA concluded that issuance of an existing stocks order was a practical necessity.  The existing stocks order includes provisions that:  (1) prohibit all sale and distribution of existing stocks of the three vacated dicamba products by the registrants, and by persons other than commercial applicators except for disposal of the products or returning the products to the registrants or their contract agents, (2) allow commercial applicators to use existing stocks of the vacated dicamba products in their possession in a manner consistent with existing labeling until July 31, 2020, and (3) prohibit end users from using existing stocks of the vacated dicamba products in their possession except in a manner consistent with existing labeling and from using such stocks in any manner after July 31, 2020.

Need for an Existing Stocks Order

To understand EPA’s position concerning the need for an existing stocks order for the three dicamba products with registrations vacated by the Ninth Circuit decision, it is important to review the legal status of those existing stocks after issuance of the decision.  In the absence of further EPA action, all stocks of the three dicamba products subject to the vacatur order that were already in channels of trade became unregistered pesticides.  Under FIFRA, as unregistered pesticides, these products could not be distributed or sold, which would prohibit stock of the unregistered products from being returned to the registrants or disposed, absent further EPA action.  Stocks of the three products that were labeled for uses other than soybeans and cotton (the uses extended by the conditional registration decision vacated by the Court) also became unregistered and thus also could not be distributed or sold absent further action by EPA.  Without further action by EPA, stocks of the three products already in the hands of end users could be lawfully used without any kind of restriction because although FIFRA Section 3(a) prohibits sale or distribution of unregistered pesticides, FIFRA does not include any provision prohibiting or limiting use of unregistered pesticides.  Thus, the Court’s vacatur action created a situation in which EPA needed to act expeditiously to establish a rational regimen governing existing stocks of the three dicamba products.  EPA was able to issue an order creating such a regimen because EPA construes the vacatur of the product registrations by Court action as a type of cancellation, which is how EPA has construed vacatur orders in the past.  FIFRA Section 6(a)(1) expressly authorizes EPA to issue orders governing sale, distribution, and use of canceled pesticides.

EPA Policy for Existing Stocks Orders

EPA adopted a policy in 1991 (56 Fed. Reg. 29362) outlining six factors it generally considers in adopting existing stocks orders for canceled pesticides under FIFRA Section 6(a)(1):  (1) the quantity of existing stocks at each level in channels of trade, (2) the risks resulting from use of existing stocks, (3) the benefits resulting from use of existing stocks, (4) financial expenditures users and others have already spent on existing stocks, (5) the risks and costs of disposal or alternative disposition of existing stocks, and (6) the practicality of implementing restrictions on the distribution, sale, or use of existing stocks.  EPA applied this policy to the current situation and determined that “[e]ach of the six factors weighs heavily in support of allowing end users to use existing stocks of these dicamba products that are in their possession.”  Since use of these unregistered pesticides is not otherwise prohibited by FIFRA as discussed above, EPA adopted prohibitions of use of the products not in accordance with the current labeling and of any use after July 31, 2020.  The only action taken by EPA to authorize further use of the three products involved stocks held by commercial applicators, which EPA allowed the commercial applicators to use according to the current labeling until July 31, 2020.

EPA Administrator Wheeler stated, “At the height of the growing season, the Court’s decision has threatened the livelihood of our nation’s farmers and the global food supply. Today’s cancellation and existing stocks order is consistent with EPA’s standard practice following registration invalidation, and is designed to advance compliance, ensure regulatory certainty and to prevent the misuse of existing stocks.”

Three days after EPA issued the dicamba existing stocks order, on June 11, 2020, the Petitioners in the National Family Farm Coalition case submitted a motion requesting that the Court provide emergency relief “to enforce its vacatur” decision and that the Court hold EPA and Administrator Wheeler in contempt.  According to the Petitioners, EPA’s entire rationale for issuing an existing stocks order is based on false premises.  In the Petitioners’ view, existing stocks of the three dicamba products are not “unregistered” because the vacatur order only invalidated certain newly authorized uses, and the existing stocks should not be deemed to be “cancelled” either, although the conditional registration decision for the products has been vacated.  In their motion, the Petitioners also assert that EPA is wrong because, “When read in context, FIFRA clearly prohibits the use of unregistered pesticides.”  In addition to their request that the Court take emergency action to enforce its decision and hold EPA in contempt, the Petitioners also requested that the Court adjudicate their Endangered Species Act (ESA) claims, an action that would require that the Court recall the mandate and issue another decision on the ESA claims it previously declined to reach.

On June 12, 2020, the Court issued an order requiring EPA to file its response to the motion by 5:00 p.m. PDT on June 16, 2020, and the Petitioners to file any reply by 5:00 p.m. PDT on June 18, 2020.

In another development, BASF Corporation and E.I. DuPont de Nemours each filed separate “emergency motions” to intervene in the case on June 12, 2020.  Each company asserts that it was not afforded notice that the Court might take adverse action concerning the registration for its dicamba product until after the decision vacating that registration was issued by the Court.  At this juncture, the Court has not yet indicated whether it will consider these emergency intervention motions or whether it would be willing to allow any further briefing on the merits of the case.

Commentary

The Court’s June 3, 2020, decision stated, “We are aware of the practical effects of our decision,” but it is not clear from the discussion that follows whether the Court fully considered the chaotic effects of issuing a vacatur decision that did not specifically address the fate of existing stocks of the dicamba products with vacated registrations.  On May 21, 2020, EPA asked for leave to file information on its plans to issue a cancellation order governing existing stocks of products with vacated registrations, but the Court declined to allow that filing.  In any case, it should not have been surprising that EPA would construe its vacatur order as a form of cancellation, because that is what EPA did when the Ninth Circuit previously issued a vacatur order for sulfoxaflor products in 2015.

The Petitioners’ motion rejecting the basic legal premises underlying the EPA existing stocks order reflects a novel view of pesticide registration that is difficult to reconcile with the plain language and established constructions of FIFRA.  Under FIFRA, EPA issues registrations for specific pesticide products, which may be labeled only for those uses that EPA has previously determined meet applicable requirements.  Under FIFRA Section 6(b), EPA can decide that particular uses no longer meet the standard for registration and must be removed from an existing product label, but the only means by which EPA can effectuate that determination is by taking action to cancel any product for which the registrant does not agree to make the necessary changes.  The Court vacated EPA’s conditional registration decision that authorized three registered dicamba products to be labeled for use on dicamba-tolerant soybeans and cotton but did not direct or establish any process for EPA to consider amending the product labeling or restoring the prior registrations.  Under these facts, EPA has concluded that under FIFRA, existing stocks that are labeled for those uses became unregistered pesticide products because the labeling no longer conforms to the product registrations as they have been altered by the Court.  In the absence of an existing stocks order, stocks of the affected products labeled for the disallowed uses could not be lawfully distributed for any purpose, including voluntary recall by the registrant, disposal, or relabeling to remove the disallowed uses.

Despite the assertions by the Petitioners that FIFRA prohibits use of unregistered pesticides, FIFRA has not been construed in this manner.  While it a violation of FIFRA to distribute or sell any pesticide product with labeling that does not conform to a valid registration, FIFRA does not include any similar prohibition on use of an unregistered pesticide.   Thus, in the absence of an existing stocks order, stocks of the three dicamba products with vacated registrations that are already in the hands of end users could be lawfully used without restriction.  This notion is reflected in the provisions addressing end users in the order.  No provision in the order authorizes end users who have the three dicamba products in their possession to do anything.  Rather, the order prohibits end users from using the three products except in compliance with the existing labeling and from using the products at all after July 31, 2020.

Of course, it is not surprising that EPA applied its established criteria for existing stocks orders in the manner that it did.  Representatives of affected growers argued that prohibiting all use of the products in the middle of the 2020 growing season would lead to billions of dollars in damages, at a time when the entire agricultural economy has already been severely impacted by the Covid-19 pandemic.

In addition to arguing that an existing stocks order was necessary to establish a practical regimen governing distribution and use of those stocks of the three dicamba products in channels of trade when the Court’s decision was issued, EPA will likely argue that the Circuit Court lacks jurisdiction to review the existing stocks order.

On June 3, 2020, the U.S. Court of Appeals for the Ninth Circuit (Ninth Circuit) issued an opinion in National Family Farm Coalition v. EPA, No. 19-70115, vacating the U.S. Environmental Protection Agency’s (EPA) 2018 decisions to extend the conditional registrations for  three reduced volatility dicamba herbicides, Bayer’s XtendiMax, Corteva’s FeXapan, and BASF’s Engenia. 

The manufacturers of these dicamba products designed them to facilitate control of glyphosate resistant weeds in strains of soybeans and cotton that have been genetically modified to be dicamba tolerant (DT).  Although the manufacturers intended these dicamba products to be less volatile and less susceptible to drift into adjacent non-target areas than previous formulations of dicamba, there were nonetheless many complaints that the products cause damage to non-tolerant crops and other vulnerable vegetation.  The Petitioners that challenged EPA’s decision to extend the conditional registrations for these reformulated dicamba products include a group representing small farmers who claim that the new dicamba products have damaged their crops (National Family Farm Coalition) and several non-governmental organizations that routinely oppose new pesticide registrations (the Center for Food Safety, the Center for Biological Diversity, and Pesticide Action Network North America). 

Although the case included some allegations by the Petitioners that EPA did not comply with the requirements of the Endangered Species Act, the court did not reach those issues.  The court found unanimously that EPA’s decision to extend the conditional registrations for the three dicamba herbicides did not satisfy the requirements of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA).  Specifically, the court found that the administrative record compiled by EPA did not include “substantial evidence” supporting EPA’s determination that registering the new uses “would not significantly increase the risk of any unreasonable adverse effects on the environment.”  EPA is required under FIFRA Section 3(c)(7)(B) to make this determination to grant a conditional registration of new uses of a currently registered pesticide.  The court concluded that EPA could not make this required determination because, the court stated, the record shows that EPA “substantially understated the risks that it acknowledged” and also “entirely failed to acknowledge other risks.”

According to the court, EPA made six material errors in its analysis supporting the registrations. First, the court stated that EPA understated the amount of acreage planted with DT crops in 2018, and consequently also underestimated the amount of the new dicamba products that would be applied that year, even though the decision to extend the conditional registrations for the new dicamba products was not issued until the end of the 2018 growing season.  Second, in the court’s view, EPA improperly found that the number of complaints concerning damage to non-target crops and vegetation by the new dicamba products might be over-reported when the record included overwhelming evidence that non-target damage was being under-reported.  Third, the court stated that EPA refused even to estimate how much damage to non-target vegetation would be caused by the new dicamba products when the record contained sufficient information for EPA to make such an estimate.  Fourth, according to the court, EPA refused to acknowledge the substantial risk of non-compliance with the large number of detailed restrictions set forth in the 40-page approved label, although the court found that “there was substantial evidence that even conscientious applicators had not been able to consistently adhere to the label requirements.”  Fifth, the court believes EPA failed to acknowledge the anti-competitive effect of the new technology, which encourages other growers to use DT crops even if they do not use the new dicamba products, to avoid damage from nearby applications.  Sixth, according to the court, EPA failed to acknowledge the social cost being caused in small communities where damage caused by use of the new dicamba products has turned formerly amicable neighbors against each other. 

Based on all of these purported deficiencies, the court held that EPA’s rationale for determining that the risk of unreasonable adverse effects would not be significantly increased by the new dicamba uses, and that the registration for the new dicamba products could therefore be extended for two additional years, was not supported by “substantial evidence” in the administrative record taken as a whole.  The court also held that remanding the matter to EPA for further action without vacatur would not be appropriate because EPA did not satisfy the requirement to extend the conditional registrations.  Instead, the court simply vacated the registrations and invited EPA to try again.  The court acknowledged that such a decision would cause disruption, especially for those growers that have already purchased DT seeds and dicamba herbicides for this year's growing season, but concluded that no remedy other than vacatur would be appropriate given the deficiencies in the administrative record.

Commentary

When FIFRA was amended to allow new pesticide products to be “conditionally” registered even though the applicants had not submitted data to satisfy all applicable requirements, the focus was primarily on allowing registration of new products that are “substantially similar” to already registered products.  FIFRA Section 3(c)(7) also allows conditional registrations to be issued for new uses of existing active ingredients and for new active ingredients without all required data if EPA has sufficient information to make certain findings while it waits for additional data, but requires that EPA be able to determine that certain requirements can be met even though not all of the supporting data that will ultimately be needed are yet available.

This court’s decision illustrates the type of problems that can occur when EPA issues a conditional registration for new products that are not “substantially similar” to registered products.  The court’s view of the sufficiency of the record in this case sets a high bar for the determinations that must support other types of conditional registrations.  This problem was previously illustrated when a reviewing court vacated a new registration for a new nanosilver product even though there were already registered nanosilver products.  In that case, because EPA chose as a matter of policy to characterize the product as a new active ingredient, it was required to make a “public interest” determination under FIFRA Section 3(c)(7)(C).  When the administrative record was deemed insufficient to support this mandatory determination, the reviewing court vacated the registration. 

In the case of the new dicamba products, to grant conditional registrations for new uses of an existing active ingredient, EPA was required to determine that the new uses on DT soybeans and cotton would not “significantly increase the risk of unreasonable adverse effects on the environment” under FIFRA Section 3(c)(7)(B).  The court found the record supporting this mandatory determination to be insufficient, resulting in the court’s vacatur of EPA’s decision.  These two reviewing courts have taken a relatively deep dive into the administrative record supporting a conditional registration for a new use of an existing active ingredient or a new active ingredient in evaluating whether substantial evidence in the record supports the determinations required by FIFRA.  Whether future decisions will maintain such a stringent evidentiary standard will be important to monitor.

On May 15, 2020, the U.S. Environmental Protection Agency (EPA) announced that it is issuing its third temporary modification to Pesticide Registration (PR) Notice 98-10 to include food-contact surface sanitizer products containing the active ingredient (AI) isopropyl alcohol.  This new temporary amendment permits all the registration modifications outlined in the March and April modifications, while also expanding the criteria for the types of products that qualify for the provisions of this amendment.

EPA states that this temporary, time-limited amendment to PR Notice 98-10, dated May 11, 2020, will extend some of the supply chain flexibilities to products used in the food manufacture and preparation industries.  Specifically, this temporary amendment expands these flexibilities to manufacturers of food-contact surface sanitizer products containing isopropyl alcohol and adds isopropyl alcohol to the list of AIs commodity chemicals allowed to be changed by notification in order to use any similar source to produce List N registered disinfectant products.

According to EPA, these isopropyl alcohol sanitizer products are not to be applied directly to food.  Instead, they are used to sanitize equipment and surfaces used in food manufacturing and food preparation.

EPA intends for these flexibilities to increase the availability of products for use against the SARS-CoV-2.  This third temporary modification to PR Notice 98-10, according to EPA, is in response to feedback from the food manufacture and preparation industries that are experiencing challenges acquiring sanitizers for use in production facilities processing low-moisture products like cereal, flour, and industrial baked goods.

On May 12, 2020, the U.S. Environmental Protection Agency (EPA) announced additional procedures for registrants to add new disinfectant products to EPA’s List N: Disinfectants for Use Against SARS-CoV-2 that are considered to be safe and effective for use against SARS-CoV-2, the virus that causes COVID-19.

EPA states that it intends to expedite reviews of certain Pesticide Registration Improvement Extension Act (PRIA 4) submissions for products intended for use against the SARS-CoV-2.  These actions include requests to amend currently registered products that require a review of efficacy data and applications for new pesticide product registrations that would qualify for List N for use against SARS-CoV-2.  This process does not replace the review process of all other submitted antimicrobial products.

EPA states that it also may consider expedited review of new active ingredients (AI) or new uses for currently registered AIs (including higher application rates, new application methods such as fogging and electrostatic sprayers, or use sites such as porous surfaces).

The following submissions may qualify for expedited review:

Amendments for Currently Registered Products

  • A request to add a virucidal claim to a product that requires EPA to review efficacy data (including both newly submitted data and citations to existing data);
  • A request to add a new unregistered source of a non-commodity active ingredient (active ingredient not listed in the May 11, 2020, Temporary Amendment to PR Notice 98-10) to a product’s Confidential Statement of Formula; and
  • A request that involves changes to a product’s formulation that requires EPA to review confirmatory efficacy data. Confirmatory efficacy data are a reduced set of data used to support certain changes in formulation to a registered product.

New Products – formulated with currently registered AIs that are contained in disinfectant and/or sanitizer pesticide products approved for use in residential, commercial, institutional, and industrial settings.

  • A submission of an application for a new pesticide product that requires EPA to review newly submitted efficacy data to support virucidal claims where the product is formulated with a registered source of active ingredient(s); and
  • A submission of an application for a new pesticide product that requires EPA to review newly submitted efficacy data to support virucidal claims where the product is formulated with an unregistered source of the active ingredient(s).

Additional information on EPA’s requirements and process for submissions to be considered for expedited review is available here

EPA also announced the availability of its new List N Tool: COVID -19 Disinfectants, a new web-based application (app) that allows smart phone users and others to access List N to identify disinfectant products that meet EPA’s criteria for use against SARS-CoV-2, the virus that causes COVID-19. 

For several months, EPA has provided the public with List N, which currently lists 410 surface disinfectant products that meet EPA’s criteria for use against SARS-CoV-2.  EPA is now making available the data from the List N webpage on a browser-based web app that allows users to identify the disinfectant products best suited for their needs.  Users can search by use site (e.g., home, business, health care, etc.), surface type (e.g., hard, non-porous surfaces like countertops; porous surfaces like fabrics), contact time (i.e., the time the product needs to be visibly wet), EPA registration number, AI(s), or product name.

On April 22, 2020, Assistant Administrator Alexandra Dapolito Dunn stated, on prerecorded remarks posted by the American Bar Association, that the U.S. Environmental Protection Agency (EPA), after the coronavirus crisis subsides, will review whether some of the current requirements to submit notifications or label amendments are necessary.  Some of these requirements have been suspended as part of EPA’s efforts to hasten the process for disinfectants approved for use against SARS-CoV-2, which causes COVID-19.

EPA modified the requirements to submit a notification or label amendment to increase quickly the number of disinfectants available to fight the novel coronavirus that causes COVID-19.  These steps include a temporary policy EPA updated on April 14, 2020, describing situations in which manufacturers producing disinfectants for use against SARS-CoV-2 can change certain ingredients or sources of those ingredients without the normal requirement to notify EPA.

On the prerecorded remarks, Assistant Administrator Dunn stated as an example, “if a baker is changing its source of flour, we don’t need to know where it’s coming from as long as it’s the same quality and the company maintains its records.”  She also remarked “dropping such ‘administrative hoops’ has helped disinfectant manufacturers get their products to market without putting public health or the environment at risk.”

EPA will proceed with formal rulemaking or another process if EPA decides to modify the requirements to keep the flexibility currently used during the COVID-19 crisis.

On April 14, 2020, the U.S. Environmental Protection Agency (EPA) announced it is taking further action to help ease the production and availability of EPA-registered disinfectants by temporarily allowing registrants to notify EPA of certain formulation and manufacturing facility changes and immediately release the product for sale without waiting for EPA approval.  This only applies to products on EPA’s List N: Disinfectants for Use Against SARS-CoV-2 (List N). 

EPA’s announcement builds on EPA’s temporary amendment to Pesticide Registration (PR) Notice 98-10 announced on March 31, 2020.  Among other changes, the temporary amendment to PR Notice 98-10 streamlines the process for adding additional registered sources of active ingredients to a formulation and setting up an approved pesticide manufacturing establishment.  This enhanced flexibility allows List N with registered sources of active ingredients to be manufactured in those establishments without prior EPA approval. 

EPA’s temporary amendment to PR Notice 98-10 states that registrants may submit a notification to substitute registered sources of active ingredients that are not similar.  If registrants are unable to substitute a similar registered source (similar defined as the active or inert ingredient obtained from the source has the same Chemical Abstracts Service Registry Number (CASRN) and same purity) of the active ingredient, they may use an alternate source but must adjust the inert ingredient to ensure the nominal concentration of the active ingredient in the product does not change.  As long as the nominal concentration of the active ingredient in the product remains the same and adjustments in inert ingredients is limited to water only, this change will be allowed by notification and confirmatory efficacy data will not be required.

Additionally, EPA’s temporary amendment to PR Notice 98-10 will allow registrants to submit a notification to add EPA-registered establishments for formulations having a registered source of the active ingredient and where there are no other changes to the formulation.

EPA states that the changes allowed through notification by this action will not result in any substantive changes to the final pesticide formulations already approved by EPA, and the products’ effectiveness will not be affected and the products’ current precautionary labeling will remain protective.  EPA adds this action will not cause any unreasonable adverse effects to human health and the environment.

EPA states in its temporary amendment to Pesticide Registration (PR) Notice 98-10, the following procedures to submit a notification for currently registered disinfectant products listed on EPA’s List N:

  • A cover letter with a subject line that clearly indicates that this is a “notification per TEMPORARY AMENDMENT TO PR NOTICE 98-10 (April 14, 2020) for EPA Registration No. XXXXXX and [insert product name]”;
  • The active ingredient; and
  • The following certification statement:

[Name of Registrant] is submitting this notification consistent with the provisions of PR Notice 98-10 and [insert section(s) of the Temporary Amendment to PR Notice 98-10 dated April 10, 2020, and no other changes have been made to the Confidential Statement of Formula or labeling of this product.  I confirm that the ingredients statement of this label remains truthful.  I understand that it is a violation of 18 U.S.C. Section 1001 to willfully make any false statement to EPA.  I further understand that if this self-certification is not consistent with the terms of PR Notice 98-10, the Temporary Amendment 98-10 dated April 10, 2020, and 40 C.F.R. 152.46, this product may be in violation of FIFRA and I may be subject to enforcement actions and penalties under section 12 and 14 of FIFRA.

Applications must be submitted via the CDX portal.  At this time, EPA is not accepting paper applications.  Once an application is submitted, EPA requests that an email is sent to the Product Manager for the product with the CDX tracking number (CDX _ 2020 _ XXXXXXX).  A registrant may distribute or sell a product modified according to this temporary amendment to PR Notice 98-10 once EPA receives the notification.  Receipt to EPA occurs when the requestor receives a CDX number when submitting the application via the CDX portal.

Additional information on submission information for registrants is available at Temporary Amendment to PR Notice 98-10 and on our blog.

On March 31, 2020, the U.S. Environmental Protection Agency (EPA) announced it is taking further action to help ease the production and availability of EPA-registered disinfectants by temporarily allowing manufacturers of certain already-registered EPA disinfectant products to obtain certain active ingredients from any source without prior approval from EPA.  This only applies to products on EPA’s List N: Disinfectants for Use Against SARS-CoV-2 (List N).  EPA announced on March 26, 2020, similar action on certain inert ingredients

EPA typically requires disinfectant manufacturers to first apply for and receive EPA approval prior to making a change in the source of the active ingredient.  Under this temporary amendment, however, manufacturers can source certain active ingredients from alternate suppliers by informing EPA.  Once EPA has been notified, the registrant can immediately distribute or sell a product modified according to this temporary amendment, provided that the resulting formulation is chemically similar to the current formulation (i.e., the purity of resulting product from the alternate source falls within the certified limits of the currently registered formulation for which they are making the source change).  EPA states that by allowing manufacturers to obtain certain active ingredients from any source it will help alleviate reports of supply chain disruptions by pesticide registrants who manufacture disinfectant products on List N.

The eligible active ingredients are:

  • Citric Acid, Chemical Abstracts Service Registry Number (CASRN) 77-92-9;
  • Ethanol, CASRN 64-17-5;
  • Glycolic Acid, CASRN 79-14-1;
  • Hydrochloric Acid, CASRN 7647-01-0;
  • Hypochlorous Acid, CASRN 7790-92-3;
  • Hydrogen Peroxide, CASRN 7722-84-1;
  • L-Lactic Acid, CASRN 79-33-4; and
  • Sodium Hypochlorite, CASRN 7681-52-9.

EPA will assess the continued need for and scope of this temporary amendment on a regular basis and will update it if EPA determines modifications are necessary.  EPA will notify the public at least seven days prior to terminating this temporary amendment at www.epa.gov/pesticides.

After the termination date of the temporary amendment, registrants will not be able to release for shipment new registered product unless that product is produced using a source of active ingredient identified in the product’s approved Confidential Statement of Formula (CSF) or otherwise would have complied with relevant requirements in the absence of this temporary amendment.

EPA states in its temporary amendment to Pesticide Registration (PR) Notice 98-10, the following procedures to submit a notification for currently registered disinfectant products listed on EPA’s List N:

  • A cover letter with a subject line that clearly indicates that this is a “notification per TEMPORARY AMENDMENT TO PR NOTICE 98-10 (Insert date or other citation) for EPA Registration No. XXXXXX and [insert product name]”;
  • The active ingredient; and
  • The following statement:

[Name of Registrant] is notifying EPA of its intent to use one or more alternate, unregistered sources of active ingredient listed in the TEMPORARY AMENDMENT TO PESTICIDE REGISTRATION (PR) NOTICE 98-10 (Insert date or other citation) in the formulation of EPA Registration No. [xxx-xx].  Each source is chemically identical to (i.e., within the certified limits of) the active ingredients in the Confidential Statements of Formula previously accepted by EPA [insert CSF date(s)]. This self-certification is consistent with the provisions of PR Notice 98-10 and no other changes have been made to the Confidential Statement of Formula or labeling of this product.  Further, I confirm that the ingredients statement of this label remains truthful.  I understand that it is a violation of 18 U.S.C. Section 1001 to willfully make any false statement to EPA.  I further understand that if this self-certification is not consistent with the terms of PR Notice 98-10 and 40 C.F.R. 152.46, this product may be in violation of FIFRA and I may be subject to enforcement actions and penalties under section 12 and 14 of FIFRA.

Applications must be submitted via the CDX portal.  At this time, EPA is not accepting paper applications.  Once an application is submitted, EPA requests that an email is sent to .(JavaScript must be enabled to view this email address) with the CDX tracking number (CDX _ 2020 _ XXXXXXX).  A registrant may distribute or sell a product modified according to this temporary amendment to PR Notice 98-10 once EPA receives the notification.
