On April 21, 2021, the U.S. Environmental Protection Agency (EPA) announced the issuance of Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) Section 18 emergency exemptions to the states of Georgia, Minnesota, and Utah permitting the use of BiaXamTM B110-V and BiaXamTM B110-P (BiaXam), adhesive film used as supplemental residual surface coating, in Delta Air Lines planes and facilities in those three states.

According to the EPA Authorizations for Georgia, Minnesota, and Utah (EPA Authorizations), the unregistered product is a transparent adhesive film that contains the unregistered active ingredient, Benzene, 1-(1,1-dimethylethyl)-4-ethenyl-, polymer with ethenylbenzene and 2-methyl-1,3-butadiene, sulfonated (CAS RN 1637665-77-0).  BiaXam is approved for use on indoor hard, nonpliable, nonporous, nonfood-contact surfaces of aircraft, airports, and associated facilities owned or operated by Delta Air Lines, to provide residual control of the SARS-CoV-2, the virus that causes COVID-19.  The adhesive film must be applied by trained applicators to indoor surfaces in airplanes, airports, and related facilities at the Delta Air Lines sites listed on the label.  Prior to application of the BiaXam product, the surface initially must be disinfected using a disinfectant from EPA’s List N – Disinfectants for Use Against SARS-CoV.

The BiaXam film is to be replaced in airplanes at least every 200 days, and in airports and related facilities at least every 100 days. If the film detaches from the surface, degrades, is damaged, becomes irreparably soiled, or its edges or corners begin to peel, the film is to be removed, the surface cleaned and dried using a List N disinfectant, and a new layer of film applied to the surface according to the application instructions on the label.  To maintain protective effect on surfaces that have been treated with BiaXam, only alcohol-based Purell wipes, Matrix Disinfectant/Cleaner #3 (quaternary ammonium based, EPA Reg. No. 1839-168-67026), and Lysol wipes (quaternary ammonium based, EPA Reg. No. 777-114) may be used on film-covered surfaces for routine cleaning and disinfection. The film surface is to be cleaned directly in place and not removed unless replacing. If cleaning products are provided to the public (e.g., airline passengers), only products compatible with BiaXamTM B110-V and BiaXamTM B110-P should be provided.

FIFRA Section 18 authorizes EPA to exempt federal or state agencies from any provision of FIFRA in the event that emergency conditions require such an exemption.  EPA regulations (40 C.F.R. Part 166) specify when state or federal government agencies will be permitted to use unregistered pesticides in response to an emergency.  EPA’s regulations provide that an emergency exists when:

  • There is an “urgent, non-routine” situation requiring the use of a pesticide to control a new pest not previously prevalent in the United States, to control significant risks to health, the environment, beneficial organisms, or endangered species, or to prevent specified types of economic loss; and
  • There is no registered pesticide or economically or environmentally feasible alternate method of control available.

40 C.F.R. § 166.3.

The exemptions granted can be very specific and time-limited; EPA has developed a database so companies can search (by chemical, site, pest, applicant, or date range) to determine if an emergency exemption has been issued and its expiration date.

EPA’s approval will allow the BiaXam product to be used at facilities owned or controlled by Delta Air Lines, Inc., at specific sites in Georgia, Minnesota, and Utah, on indoor hard, nonpliable, nonporous, and nonfood-contact surfaces in airplanes, airports, and other air-travel related facilities owned or controlled by Delta Air Lines, Inc. including, but not limited to:

  • Airplanes: railings, doorknobs/handles, armrests, seatback touch screens, seatbelt buckles, window shades, overhead bins, and overhead control buttons.
  • Airports and other air-travel related facilities: check-in kiosks and counters, gate counters, railings, doorknobs/handles, luggage bins, desks, keyboards, computer mice, touchscreens, printers, badge readers, plastic divider walls, hard nonporous seating, armrests, and elevator buttons.

The approved Section 18 emergency requests are effective for one year.  Any unexpected adverse effects related to the use of this product must be reported immediately to EPA as required under the terms of the FIFRA Section 18 emergency exemption approval.

On January 19, 2021, the U.S. Environmental Protection Agency (EPA) announced the issuance of a Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) Section 18 emergency exemption to the states of Oklahoma and Arkansas, permitting American Airlines to use SurfaceWise2, believed to inactivate coronaviruses like the SARS-CoV-2 virus on surfaces, in specific airport facilities and planes.  EPA also has revised the terms of use for SurfaceWise2 for all current emergency exemptions. 

EPA’s initial emergency exemption for the state of Texas issued on August 24, 2020, specified that the product remained effective for seven days.  According to its updated labels for all three states, EPA has now approved claims that SurfaceWise2 provides residual surface control of the coronavirus SARS-CoV-2 on surfaces that are undisturbed for up to 30 days.  The updated labels state “When used in accordance with the directions for use, SurfaceWise®2 provides residual surface control of coronaviruses, including SARS-CoV-2, for up to 30-days on undisturbed (e.g., are not routinely disinfected with List N products) non-porous treated surfaces.” 

Of note, EPA also states in its announcement that SurfaceWise2 should be reapplied every time surfaces are disinfected to ensure continuous product performance as exposure to prolonged wetness may adversely impact the efficacy of the product.  The updated labels state in the Directions for Use that the user must “Reapply SurfaceWise®2 after surfaces are disinfected to ensure continuous product performance” and “Do not expose SurfaceWise®2 to prolonged wetness as this may adversely impact the efficacy of the product.”

FIFRA Section 18 authorizes EPA to exempt federal or state agencies from any provision of FIFRA in the event that emergency conditions require such an exemption.  EPA regulations (40 C.F.R. Part 166) specify when state or federal government agencies will be permitted to use unregistered pesticides in response to an emergency.  EPA’s regulations provide that an emergency exists when:

  • There is an “urgent, non-routine” situation requiring the use of a pesticide to control a new pest not previously prevalent in the United States, to control significant risks to health, the environment, beneficial organisms, or endangered species, or to prevent specified types of economic loss; and
  • There is no registered pesticide or economically or environmentally feasible alternate method of control available.

40 C.F.R. § 166.3.

The exemptions granted can be very specific and time-limited; EPA has developed a database so companies can search (by chemical, site, pest, applicant, or date range) to determine if an emergency exemption has been issued and its expiration date.

In this case, EPA approved the Section 18 emergency exemption request for SurfaceWise2 -- a product manufactured by Allied BioScience.  SurfaceWise2 is a surface coating that Allied BioScience states inactivates viruses and bacteria within two hours of application and continues to work against them for up to 30 days, on undisturbed non-porous treated surfaces.  EPA’s approvals will allow Texas, Oklahoma, and Arkansas to permit American Airlines airport facilities and planes at specific locations identified on the label and two Total Orthopedics Sports & Spine Clinics in Texas to use SurfaceWise2 under certain conditions.  The approved Section 18 emergency requests are effective for one year. This public health exemption will expire August 24, 2021.  As new data emerge, EPA may alter the terms of the product’s emergency uses, as it did with the modifications discussed here.

On January 15, 2021, the U.S. Environmental Protection Agency (EPA) announced the issuance of a Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) Section 18 emergency exemption to the states of Georgia and Tennessee permitting the use of an air treatment product, Grignard Pure, in health care facilities, intrastate transportation, food processing facilities, and indoor spaces within buildings -- including government facilities -- where people are conducting activity deemed essential by the state.  According to the EPA Authorizations for Georgia and Tennessee (EPA Authorizations), Grignard Pure forms a mist with activity against airborne SARS-CoV-2, the virus that causes COVID-19.  It contains the active ingredient triethylene glycol (TEG), an ingredient commonly used in fog machines for concerts and theater productions. 

FIFRA Section 18 authorizes EPA to exempt federal or state agencies from any provision of FIFRA in the event that emergency conditions require such an exemption.  EPA regulations (40 C.F.R. Part 166) specify when state or federal government agencies will be permitted to use unregistered pesticides in response to an emergency.  EPA’s regulations provide that an emergency exists when:

  • There is an “urgent, non-routine” situation requiring the use of a pesticide to control a new pest not previously prevalent in the United States, to control significant risks to health, the environment, beneficial organisms, or endangered species, or to prevent specified types of economic loss; and
  • There is no registered pesticide or economically or environmentally feasible alternate method of control available.

40 C.F.R. § 166.3.

The exemptions granted can be very specific and time-limited; EPA has developed a database so companies can search (by chemical, site, pest, applicant, or date range) to determine if an emergency exemption has been issued and its expiration date.

EPA’s approval will allow the Grignard Pure product to be applied in Georgia and Tennessee in certain indoor spaces where adherence to current public health guidelines is impractical or difficult to maintain.  The areas where it can be used under the exemption include breakrooms, locker rooms, bathrooms, lobbies, elevators, eating areas, and food preparation areas within health care facilities, intrastate transportation, food processing facilities, and indoor spaces within buildings.  According to the EPA Authorizations, Grignard Pure may only be applied by trained professionals through a building’s HVAC system or using portable devices positioned strategically in an indoor space.  Additionally, the label states that use of Grignard Pure does not eliminate the need for critical precautions like mask wearing and social distancing.  Signs must be posted to indicate that a space is being treated and to advise that the product may cause temporary irritation to sensitive individuals.

Based on a review of laboratory testing data, EPA states that it expects that when used as directed, Grignard Pure will inactivate continuously 98 percent of airborne SARS-CoV-2 particles. Grignard Pure was tested against a surrogate virus that is harder to kill than SARS-CoV-2.

The approved Section 18 emergency requests are effective for one year.  Any unexpected adverse effects related to the use of this product must be reported immediately to EPA as required under the terms of the FIFRA Section 18 emergency exemption approval.

On August 24, 2020, the U.S. Environmental Protection Agency (EPA) announced the issuance of a Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) Section 18 emergency exemption to the state of Texas permitting it to allow American Airlines and Total Orthopedics Sports & Spine to use a new product that is believed to inactivate coronaviruses like the SARS-CoV-2 virus on surfaces for up to seven days.  EPA states that after carefully reviewing the available data and information, it “determined that the product helps to address the current national emergency.”  According to EPA, the product is “expected to provide longer-lasting protection in public spaces, increasing consumer confidence in resuming normal air travel and other activities.”

FIFRA Section 18 authorizes EPA to exempt federal or state agencies from any provision of FIFRA in the event that emergency conditions require such an exemption.  EPA regulations (40 C.F.R. Part 166) specify when state or federal government agencies will be permitted to use unregistered pesticides in response to an emergency.  EPA’s regulations provide that an emergency exists when:

  • There is an “urgent, non-routine” situation requiring the use of a pesticide to control a new pest not previously prevalent in the United States, to control significant risks to health, the environment, beneficial organisms, or endangered species, or to prevent specified types of economic loss; and
  • There is no registered pesticide or economically or environmentally feasible alternate method of control available.

40 C.F.R. § 166.3.

The exemptions granted can be very specific and time-limited; EPA has developed a database so companies can search (by chemical, site, pest, applicant, or date range) to determine if an emergency exemption has been issued and its expiration date.

In this case, EPA approved the Section 18 emergency exemption request for SurfaceWise2 -- a product manufactured by Allied BioScience -- a surface coating that Allied BioScience states inactivates viruses and bacteria within two hours of application and continues to work against them for up to seven days, between regular cleanings.  EPA’s approval will allow Texas to permit American Airlines airport facilities and planes at specific locations and two Total Orthopedics Sports & Spine Clinics to use SurfaceWise2 under certain conditions.  The approved Section 18 emergency requests are effective for one year. As new data emerge, EPA may alter the terms of the product’s emergency uses.

Over the coming months, Allied BioScience will pursue a non-emergency approval under FIFRA Section 3 by submitting additional data to meet EPA’s registration requirements as an antiviral and antibacterial surface coating.  If the full registration process is completed, the product would become available for purchase by members of the public.  SurfaceWise2 is not yet available to the general public because Allied Biosciences has not yet submitted the necessary data to qualify for registration under Section 3 of FIFRA.

Commentary

EPA states that it has not received any other Section 18 applications for products with residual efficacy against coronaviruses like SARS-CoV-2, but that is likely to change following this approval and ongoing activities by companies seeking options for products to use against SARS-CoV-2.  EPA states it will consider any such requests submitted related to the COVID-19 public health emergency, and also anticipates posting information for companies or individuals who are interested in pursuing a FIFRA Section 3 registration for antiviral surface coatings in the coming weeks.

States or federal agencies interested in pursuing a Section 18 emergency exemption request for products that claim residual efficacy against viruses should be prepared to include efficacy data demonstrating that the product is durable and effective against viruses for up to the periods of time after application.  It will be essential to ensure that these data will be deemed sufficient by EPA to determine efficacy and durability, which may require discussion with EPA.  EPA will review the results of these studies to ensure that surface coatings remain effective under the anticipated proposed conditions of use.

On June 22, 2020, the U.S. District Court for the Eastern District of California granted summary judgment for the Plaintiffs in National Association of Wheat Growers et. al. v. Becerra, and entered a permanent injunction against enforcement of a Proposition 65 (Prop 65) warning label for pesticide products containing glyphosate.  The court found that requiring the registrants of glyphosate products to include such a warning could not be justified as a valid restriction on commercial speech and therefore is contrary to the First Amendment of the Constitution.  The same District Court had previously entered a preliminary injunction against the Prop 65 warning in 2018, and the required warning has consequently never been in effect. (See our February 28, 2018, blog entitled “Eastern District of California Rules on Motion to Enjoin Prop 65 Listing and Warning on Glyphosate Products.”)  The U.S. Environmental Protection Agency (EPA) also has stated that it would not allow a Prop 65 warning to be added to the labeling for any registered glyphosate product because such a warning is misleading and would cause the product to be “misbranded” under Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) Section 2(q)(1)(A). (See our August 15, 2019, blog entitled “EPA Issues Guidance Regarding Prop 65 Labeling Requirements for Glyphosate Products and OEHHA Responds.”)

A Prop 65 warning is required when the California Office of Environmental Health Hazard Assessment (OEHHA) determines that a product contains a substance that has been classified as a human carcinogen by certain authoritative bodies, including the International Agency for Research on Cancer (IARC).  Based on an IARC determination that glyphosate is “probably carcinogenic” in humans, OEHHA listed glyphosate in July 2017 as a chemical known to the State of California to cause cancer, thereby triggering Prop 65 warning requirements.  Despite the IARC determination, every other authoritative body that has considered the matter (including EPA, the European Commission, and the World Health Organization) has reached a contrary determination that glyphosate is not likely to be carcinogenic in humans.  California’s imposition of a Prop 65 warning for glyphosate was challenged in 2018 by the registrant Bayer and a coalition of farming groups and industry stakeholders, who obtained a preliminary injunction against enforcement of the warning.

Before entering the new permanent injunction, the District Court considered whether California’s regulation of commercial speech should be scrutinized under the lower standard set by the Supreme Court in Zauderer v. Office of Disciplinary Counsel or the intermediate standard set by Central Hudson Gas & Electric v. Public Service Commission.  The Zauderer standard only applies to mandatory disclosure of “purely factual and uncontroversial information,” and the Court found that the Prop 65 warning for glyphosate is “misleading” and therefore neither factual nor uncontroversial.  Under the Central Hudson level of scrutiny, a governmental agency may only restrict commercial speech when the restriction directly advances an important governmental interest and where the restriction is not more extensive than necessary to serve that interest.  The Court found that the Prop 65 warning for glyphosate is misleading, and therefore does not directly advance the interest of the state in informing consumers regarding potential cancer hazards, and that the asserted state interest could be effectively advanced by other measures that do not burden freedom of speech in the same manner.

California argued that no Prop 65 warning would actually be required for glyphosate in practice because OEHHA has set a quantitative “safe harbor” level for glyphosate exposure, but the court found that this would not prevent parties other than California from bringing separate enforcement actions to enforce the listing.  Since a Prop 65 warning only needs to be “clear and reasonable,” California also proposed several alternative forms for a warning that would meet state requirements, but the court found these alternate warnings to all be misleading as well.  Based on all of these factors, the court decided to enjoin permanently the enforcement of Prop 65 warning requirements for glyphosate as an unconstitutional burden on commercial speech.

Commentary

Under FIFRA Section 24(b), no state may impose any labeling for a registered pesticide that differs from the labeling approved by EPA.  Although EPA has sometimes been willing to accommodate state labeling requirements or preferences within the labeling approved under FIFRA, there are necessary limits to this practice.  When label language sought by a state becomes misleading, approving it would also be expressly contrary to FIFRA.  How much precedential effect this decision may have with respect to other state requirements for labeling in the future is an issue that registrants should monitor closely.

On April 3, 2020, the California Department of Pesticide Regulation (DPR) announced it would allow enforcement discretion by County Agricultural Commissioners (CAC) for licensing and certification requirements for pesticide applicators who perform sanitization services to control the spread of COVID-19.

DPR states in its announcement that, under normal circumstances, a “Pest Control Business (PCB) must always have a Qualified Applicator License (QAL) holder to supervise pest control services.  Generally, where a PCB performs sanitization services, the QAL must also be certified in Category A, P, or K” described as follows:

  • Category A allows PCBs to perform sanitization or disinfection in residential, industrial, or institutional (RII) use settings such as hospitals, schools, or prisons;
  • Category P allows PCBs to perform microbial pest control in RII use settings; and
  • Category K allows PCBs to perform health related pest control services under a government-sponsored program.

DPR acknowledges that due to Governor Newsom’s March 4, 2020, “Stay at Home” Executive Order, DPR cannot proctor in-person licensing examinations to certify licensees.  DPR thus announced that it will use enforcement discretion by allowing “licensed and registered PCBs to perform sanitization services for the control of COVID-19 if they have a designated individual at each business location with a valid QAL in any category” (emphasis added by DPR).  DPR specifies that enforcement discretion applies when all of the following conditions are met:

  1. The professional sanitization service is performed for COVID-19 control and only during the next 90 days.
  2. The PCB without the specific QAL license category notifies the CAC in writing with an explanation for why the sanitization work is necessary.
  3. Examples of necessary work may include situations in which the PCB is the only licensee registered to do business in the county or where other properly licensed PCBs are unavailable to perform COVID-19-related work.
  4. The QAL holder ensures that all applicators applying antimicrobials are properly trained and are in strict compliance with label directions and all other applicable laws and regulations.

The announcement states that those who wish to obtain more information should contact Joe Marade, DPR’s County/State Liaison, at .(JavaScript must be enabled to view this email address).

On October 31, 2019, as required by the 2018 Farm Bill, the U.S. Department of Agriculture’s (USDA) Agricultural Marketing Service published its interim rule, “Establishment of a Domestic Hemp Production Program” (Interim Rule).  The Interim Rule proposal specifies rules and regulations governing hemp production in the U.S., including:

  • Requirements for state/tribal plans for states pursuing regulatory authority over hemp production;
  • Recordkeeping requirements;
  • Licensing requirements;
  • Delta-9 tetrahydrocannabinol (THC) testing;
  • Procedures for disposing of non-compliant plants; and
  • Compliance provisions and procedures for handling violations.

The Interim Rule does not alter the federal definition distinguishing hemp from marijuana, a distinction hinging on the levels of THC in the plant. Plants containing 0.3 percent or less THC on a dry weight basis are considered hemp, while plants exceeding this level of THC are marijuana. The Interim Rule introduces the term “acceptable hemp THC level” to account for a degree of uncertainty in testing results and explains how to interpret lab results with a measurement of uncertainty.  This is a critical clarification given that THC levels dictate whether a grower is engaged in the legal production of hemp or is growing marijuana -- prohibited federally and in the majority of states.

The USDA is not proposing a single uniform testing method and will accept numerous testing methods and protocols employed by states. The Interim Rule does not include a federal seed certification program. The Interim Rule makes clear that interstate transport of hemp is permissible regardless of whether the states the shipment passes through allow hemp production.

The publication of the Interim Rule initiates USDA’s implementation of the hemp program, which includes reviewing state/tribal plans and issuing licenses. USDA will accept public comments on the Interim Rule for 60 days through December 30, 2019.  Within two years of publication, USDA will publish a final rule.  Also relevant for hemp producers are forthcoming proposals from the U.S. Food and Drug Administration and the U.S. Environmental Protection Agency (EPA) addressing the sale of cannabidiol (CBD) and pesticide approvals for application to hemp plants, respectively.

Commentary

For some, federal policies facilitating hemp production not only is a long-awaited policy goal, but a kind of “gateway drug” (pun intended) for renewing the debate about approval for pesticide products to be used on the legal production of marijuana crops.

To date, the federal government position is that since marijuana production is not allowed under federal law, attempts by states to permit pesticides for state use are forbidden.  Some states have argued that since their state law allows the production of marijuana crops, pesticide products should be subject to registration under Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) Section 18 emergency use or FIFRA Section 24(c) special local needs.

Separate from any debate about marijuana production, residues of pesticides on hemp products intended for human consumption, such as CBD products, will force EPA to consider how such products should be reviewed.  Those policies, in time, will be relevant to any eventual evaluation of similar exposure and risk assessment questions regarding approval of pesticide products to be used in marijuana production.

On August 14, 2019, the California Department of Pesticide Regulation (DPR) issued cancellation notices to thirteen California registrants of pesticide products containing chlorpyrifos, including Dow Agrosciences LLC (now Corteva).  Each of these notices is referred to as an "Accusation," and each affected registrant has 15 days to request a hearing concerning the proposed cancellation.  DPR's issuance of these notices followed a final decision by the U.S. Environmental Protection Agency (EPA) to deny an administrative petition to revoke the tolerances and cancel the U.S. registrations for chlorpyrifos.  DPR states: "Despite the Trump administration's reversal of a decision to ban the pesticide at the federal level, California continues to move forward to protect public health, workers, and the environment."  Although it is unusual for a State to act unilaterally to cancel a State registration for a pesticide that is still registered under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), FIFRA Section 24(a) provides that States may separately regulate Federally registered pesticides so long as they do not purport to authorize any sale or use that is otherwise prohibited under FIFRA.

The risk assessment that supports DPR's proposal to cancel chlorpyrifos products is based on five animal studies published in 2016, 2017, and 2018, that report neurotoxicity from chlorpyrifos at exposure levels that are considerably lower than the levels that cause acetylcholinesterase inhibition.  Based on its evaluation these studies, DPR has concluded that developmental neurotoxicity is the critical endpoint for chlorpyrifos and has derived a point of departure for chlorpyrifos risk assessment.  Based on this assessment, DPR previously concluded that chlorpyrifos should be designated as a Toxic Air Contaminant (TAC).  DPR presented its TAC findings to California's Scientific Review Panel at a meeting on July 30, 2018, and the Panel subsequently concluded that the DPR assessment of the developmental neurotoxicity of chlorpyrifos was "based on sound scientific knowledge, and represents a balanced assessment of our current scientific understanding."

On the same day DPR issued its cancellation notices for chlorpyrifos, DPR also announced it has established an Alternatives to Chlorpyrifos Work Group with experts from "agriculture, California universities, environmental justice groups, farmworker health and safety organizations, and pesticide manufacturers…"  DPR has asked this Work Group to develop short-term practical alternatives to chlorpyrifos, along with a five-year action plan.  The Work Group is supposed to conclude its work by the spring of 2020.  The budget for 2019-2020 approved by the California Legislature also includes $5 million in grant funding to develop sustainable alternatives to chlorpyrifos.

Commentary

The DPR decision to cancel chlorpyrifos relies primarily on new animal studies that report that chlorpyrifos causes neurodevelopmental effects at levels that are well below those that inhibit cholinesterase.  DPR refers in passing to the epidemiology studies for chlorpyrifos that EPA used to make its Food Quality Protection Act (FQPA) determination for all organophosphate (OP) pesticides, but these data were not used by DPR to derive its point of departure for chlorpyrifos risk assessment.

EPA scientists have not yet prepared a formal evaluation of the new animal studies for chlorpyrifos, but EPA's decision to deny the petition to revoke tolerances and cancel registrations for chlorpyrifos states that EPA intends to evaluate the new animal studies as part of its registration review deliberations for chlorpyrifos.  The FIFRA registrations for chlorpyrifos may also be affected by pending judicial actions challenging EPA's decision to deny the petition to revoke the tolerances and cancel the registrations for chlorpyrifos.  In this complicated environment, it will be important to monitor the registrants’ and industry’s response to DPR's cancellation actions, as well as their efforts on the pending Federal court litigation and EPA's registration review process for chlorpyrifos.

On August 7, 2019, EPA took long awaited action concerning the inclusion of Prop 65 warning statements for glyphosate on EPA registered pesticide labels, which will likely impact the broader ongoing debate over EPA approval of Prop 65 warnings on pesticide labels.  EPA’s August 7, 2019, letter to glyphosate registrants states that EPA “will no longer approve labeling that includes the Proposition 65 warning statement for glyphosate-containing products.”  EPA stated further that “[t]he warning statement must also be removed from all product labels where the only basis for the warning is glyphosate and from any materials considered labeling under FIFRA for those products.”   Moreover, EPA unequivocally states that “pesticide products bearing the Proposition 65 warning statement due to the presence of glyphosate are misbranded” under FIFRA Section 2(q)(1)(A).  Registrants with glyphosate products currently bearing Prop 65 warning language, where the exclusive basis for such warning is based on the presence of glyphosate, must submit draft amended labeling that removes this language by November 5, 2019.

By way of background, California’s Office of Environmental Health Hazard Assessment (OEHHA) listed glyphosate as a chemical known to the state of California to cause cancer on July 7, 2017.  OEHHA’s listing of glyphosate as a substance under Prop 65 is based on the International Agency on the Research for Cancer (IARC) classifying it as “probably carcinogenic to humans.”  EPA scientists subsequently completed an independent review of the available scientific data on the potential carcinogenicity of glyphosate and do not agree with the IARC classification. Additional information regarding glyphosate is available at B&C’s blog.

Also of note is a February 26, 2018, preliminary injunction issued by the U.S. District Court for the Eastern District Court of California, in response to a motion filed by a coalition including Monsanto, CropLife America, and several growers associations alleging that the IARC classification decision for glyphosate is contrary to the international scientific consensus, that the required Prop 65 warning would be misleading to the ordinary consumer, that compelling the manufacturers of glyphosate to provide such a warning would violate the First Amendment because the warning is not factual and uncontroversial, and that the applicable criteria for injunctive relief were met.  The February 26, injunction precluded OEHHA from enforcing its Prop 65 warning requirements against glyphosate registrants that otherwise would have taken effect on July 7, 2018.  The Court did not rule that glyphosate should be removed from the Prop 65 list as a chemical known to the State of California to cause cancer, but did state that products containing glyphosate would not be required to comply with the warning requirements.  In issuing the preliminary injunction, the Court stated that the required warnings are “false and misleading” and that plaintiffs “have shown that they are likely to succeed on the merits of their First Amendment claim, are likely to suffer irreparable harm absent an injunction, and that the balance of equities and public interest favor an injunction, the court will grant plaintiffs’ request to enjoin [Prop 65]’s warning requirement for glyphosate.”  More information on that case is available at B&C’s blog.  That injunction has not been appealed and remains in place.

Although the glyphosate warning that EPA has refused to allow is based on OEHHA’s recent listing under Prop 65, Prop 65 warnings on pesticide labels generally have been a significant issue since 2016 when OEHHA issued revised regulations regarding the content and transmission of Prop 65 warnings.  As a result of these revisions, many registrants sought to add Prop 65 warning requirements to pesticide labels to meet Prop 65 requirements, but many registrants have not been able to obtain EPA approval for such warnings, resulting in much controversy and discussion.  More information regarding the changes to Prop 65 warning requirements also are available at B&C’s blog.

In its press release announcing its guidance to glyphosate registrants, EPA Administrator Andrew Wheeler states: “It is irresponsible to require labels on products that are inaccurate when EPA knows the product does not pose a cancer risk. We will not allow California’s flawed program to dictate federal policy.”  EPA states that its “independent evaluation of available scientific data included a more extensive and relevant dataset than IARC considered during its evaluation of glyphosate, from which the agency concluded that glyphosate is ‘not likely to be carcinogenic to humans.’”  Wheeler is further quoted as stating: “It is critical that federal regulatory agencies like EPA relay to consumers accurate, scientific based information about risks that pesticides may pose to them. EPA’s notification to glyphosate registrants is an important step to ensuring the information shared with the public on a federal pesticide label is correct and not misleading.”

OEHHA immediately released its own press release on August 13, 2019, in which it “objects to US EPA’s characterization of any warning concerning glyphosate’s carcinogenicity as a false claim.’”  After reiterating OEHHA’s listing glyphosate based on the IARC determination, OEHHA states that EPA’s position “conflicts with the determination made by IARC” and that “it is disrespectful of the scientific process for US EPA to categorically dismiss any warnings based on IARC’s determinations as false.”

Commentary

The Court’s February 26, 2018, preliminary injunction was considered a significant development both for glyphosate specifically and perhaps for Prop 65 warning requirements generally, especially considering the recent influx to EPA of label amendments seeking EPA approval of revised Prop 65 warning language to address OEHHA’s revised regulatory changes.  EPA’s guidance is equally significant, as EPA has now rejected the inclusion of a Prop 65 warning that EPA believes is misleading on a federal pesticide product label.

FIFRA Section 24(b) expressly prohibits any State from requiring any label language for a registered pesticide product beyond the labeling approved by EPA, and EPA has now declined to approve pesticide labeling that includes the Prop 65 warning for glyphosate. In some instances, EPA has been willing as a courtesy to approve labeling changes requested by a State, but the glyphosate determination demonstrates that EPA will not accept any label revisions that conflict materially with its own determinations.  Although glyphosate is a fairly complex and controversial case, it will be important for registrants to monitor the evolution of EPA’s standard for when it will or will not approve a Prop 65 warning on a federal label, since this issue has been the subject of considerable controversy over the past several years.

On November 7, 2018, the U.S. Environmental Protection Agency (EPA) announced that it was ordering Pool Water Products Inc. to stop selling an improperly registered pesticide, ALL CLEAR 3” Jumbo Chlorinating Tablets.  The announcement states that even though the ALL CLEAR 3” Jumbo Chlorinating Tablets product was registered with EPA, Pool Water Products was selling and distributing an unregistered version of the product made in China that has not been evaluated by EPA.

EPA’s action, which it states applies to nationwide distribution, transport and sales of the product, follows a statewide stop-sale order issued earlier this month by the Arizona Department of Agriculture when state inspectors discovered the unregistered pesticide, which is used to disinfect pools, during an August 30 inspection of the company’s Phoenix warehouse.

This case exemplifies the need for companies to understand Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) registration and amendment requirements, and the importance that a product’s label, formula, and manufacturing process match exactly with the information submitted to EPA and upon which EPA relied in approving the registration.  Many composition and processing changes require an amendment to be approved by EPA; failure to do so could result in an enforcement action such as this one.
