On October 30, 2020, the U.S. Environmental Protection Agency’s (EPA) Office of Enforcement and Compliance Assurance (OECA) announced that it issued a Compliance Advisory on ultraviolet (UV) lights claiming to kill or be effective against viruses and bacteria. 

EPA states that the Advisory was issued to provide an explanation to the UV light industry that UV lights are regulated under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) as pesticide devices when sold or distributed with claims to kill or be otherwise effective against viruses and/or bacteria, unless an exception applies, and must comply with certain statutory and regulatory requirements.  This is the second Compliance Advisory issued by EPA relating to UV light devices, as an Advisory issued in May 2020 entitled “What You Need to Know Regarding Products Making Claims to Kill the Coronavirus Causing COVID-19” also addressed in part whether UV light devices could make claims against the coronavirus.

The Advisory reiterates that UV lights sold or distributed with claims that the lights can be used for preventing, destroying, repelling, trapping, or mitigating any pests, which include plants, animals, viruses, bacteria, or other micro-organisms, are regulated by EPA under FIFRA as a device.  UV lights without such claims would not be subject to FIFRA.  According to the Advisory, pesticidal devices are subject to certain regulatory requirements under FIFRA, one of which is a prohibition of false or misleading labeling claims. 

The Advisory answers the following questions:

How do I comply with FIFRA if I am selling or distributing a UV light with pesticidal claims?

  • Devices do not need to be registered by EPA and, therefore, are not subject to a pre-market review by EPA (although some states require devices to be registered). However, federal regulations require devices to be produced in an EPA-registered pesticide producing establishment and there are production reporting requirements; see 40 C.F.R Part 167.
  • Devices must be labeled per federal regulations at 40 C.F.R Part 156. Generally, device labels must include warning and caution statements, directions for use and the EPA establishment number, amongst other label requirements. A description of device label requirements can be found at https://www.epa.gov/pesticide-registration/pesticide-registration-manual-chapter-13-devices#labeling.  
  • All claims in connection with the sale or distribution of a device must be true and not misleading. FIFRA Section 12(a)(1)(F) specifically prohibits false or misleading labeling (known as misbranding); this includes claims made in marketing materials and on websites. Examples of misbranding are provided at 40 C.F.R 156.10(a)(5) and include, but are not limited to, false or misleading statements concerning product effectiveness (known as efficacy), claims about product safety, false or misleading comparisons with other pesticides or devices, or any statement directly or indirectly implying that the device is recommended or endorsed by any agency of the Federal Government.  Companies are advised to maintain records, with information and data, to substantiate that claims made in regard to devices are not false or misleading.

In addition to FIFRA requirements, importers of all FIFRA-regulated devices must comply with the U.S. Customs and Border Protection (CBP) regulations set forth at 19 C.F.R. §§ 12.110 -12.117. Regulated entities that are importing UV pesticide devices are advised that the products being imported must be in compliance with FIFRA prior to entry into the United States. The EPA regularly coordinates with CBP to identify and reject violative UV pesticide devices at the port of entry.

Can a UV light be a pesticide requiring EPA registration?

Yes. If the UV light product incorporates a substance or mixture of substances to perform its intended pesticidal purpose, then it is considered a pesticide product, not a device, and must be registered with EPA in accordance with FIFRA Section 3 before it can be lawfully sold or distributed in the United States. 

Are UV lights safe and effective?

Unlike chemical pesticides, EPA does not routinely review the safety or efficacy of UV light devices and, therefore, EPA has not conducted a human health risk assessment to determine the safety of these products. For the same reason, EPA cannot confirm whether, or under what circumstances, UV light devices might be effective against any pest, including viruses and bacteria. The effectiveness of any UV light device will depend on a variety of factors including, but not limited to, the device’s duration of use, distance of the light from the surface intended to be treated, the UV wavelength, the specific pest being targeted, the strength or wattage of the UV light bulb, the age of the UV light bulb, shadow areas or other factors. 

Consumers are advised to use all pesticidal devices ONLY in accordance with the Directions for Use, which are required to appear on the product label. EPA recommends that consumers contact the manufacturer or seller of the pesticidal device directly if they have any questions about how to use the product, the product’s safety, or the product’s efficacy.

What are the compliance concerns related to UV lights?

There may be members of the UV light industry who are unfamiliar with FIFRA and may not be aware of statutory and regulatory requirements. For example, they may be unaware that it is a violation of FIFRA to sell or distribute pesticidal UV light devices that are misbranded or that have not been produced in an EPA-registered establishment. EPA has been receiving complaints that UV light devices may be in violation of FIFRA. These complaints are being reviewed and EPA intends to pursue enforcement, as appropriate. See EPA’s May 2020 compliance advisory on products making claims to kill the coronavirus that causes COVID 19 at https://www.epa.gov/sites/production/files/2020-05/documents/cornavirus-compliance-advisory.pdf and any subsequent updates.

Regulated entities of any size who voluntarily discover, promptly disclose, expeditiously correct, and take steps to prevent recurrence of potential violations may be eligible for a reduction or elimination of any civil penalties that otherwise might apply. To learn more about the EPA’s violation disclosure policies, including conditions for eligibility, please review EPA’s Audit Policy website at https://www.epa.gov/compliance/epas-audit-policy. Most violations can be disclosed and processed via EPA’s automated online “eDisclosure” system - https://www.epa.gov/compliance/epas-edisclosure. Many states also offer incentives for self-policing; please check with the appropriate state agency for more information.

Are you unsure if your product is a device under FIFRA?

EPA has developed a guide concerning pesticide devices that explains what a pesticide device is and how it differs from a pesticide product which requires registration. This guide may be helpful to UV light manufacturers who need to determine if their product is regulated by FIFRA.See https://www.epa.gov/safepestcontrol/pesticide-devices-guide-consumers. If you are still uncertain about whether your UV light product is a device, you may submit a request for a Device Determination from EPA. Instructions for submitting a request can be found at: https://www.epa.gov/pesticide-registration/pesticide-registration-manual-chapter-13-devices#obtain.

Discussion

UV light devices are a heightened focus of EPA, whose import and enforcement officials have been reviewing materials (e.g., import documents, websites) related to devices and increasingly bringing enforcement actions against companies for FIFRA violations.  These actions can address circumstances when a pesticide device is not produced in a registered establishment or when the label does not include certain requirement elements, but more recently EPA seems particularly interested in the claims that are being made with regard to these devices and whether those claims are “false and misleading” under EPA’s regulations. 

Ensuring that claims related to the efficacy of the device are not considered by EPA to be “false and misleading” can be especially difficult based on the facts that EPA does not review and approve data that support the claims being made, and also that EPA has not historically provided guidance as to the type of data that it would require to support an efficacy claim for a pesticide device.  This Advisory is interesting to the extent that EPA sets forth various factors to be considered when determining the effectiveness of a UV light device.  These factors include, but are not limited to “the device’s duration of use, distance of the light from the surface intended to be treated, the UV wavelength, the specific pest being targeted, the strength or wattage of the UV light bulb, the age of the UV light bulb, shadow areas or other factors.”  The May 2020 Advisory further states that “UV lights and other pesticide devices may not be able to make claims against coronavirus where devices have not been tested for efficacy or safety for use against the virus causing COVID-19 or harder-to-kill viruses.”  (Emphasis in original.)  In light of the two advisories, it is critical for pesticide device producers to review carefully the data supporting the claims made for their devices to ensure that they comply with the regulatory requirements under FIFRA.

On June 1, 2020, the U.S. Environmental Protection Agency’s (EPA) Office of Enforcement and Compliance Assurance (OECA) announced that it issued a compliance advisory on products claiming to kill SARS-CoV-2, the novel coronavirus that causes COVID-19.

EPA states that the advisory was issued because it has received tips and complaints concerning potentially false or misleading claims, including efficacy claims, associated with pesticides and devices.  EPA says it is actively reviewing these claims and is working to identify others.  EPA states that it intends to pursue enforcement for those products making false and misleading claims regarding SARS-CoV-2.  EPA has made available a webpage where tips can be reported.

The advisory reiterates EPA’s message that disinfectant products that claim to kill viruses must be registered with EPA before they can be sold and that pesticide products cannot legally make claims that they kill a particular pathogen, such as SARS-CoV-2, unless EPA has authorized the claim during the registration process.

In the advisory, EPA emphasizes that it will not register a product claiming to be effective against SARS-CoV-2 until it has determined that the product will not pose an unreasonable risk and will be effective when used according to the label directions.  EPA notes that it maintains List N, which is a list of disinfectants that meet EPA’s criteria for use against the virus that causes COVID-19.  While surface disinfectant products on List N have not been tested specifically against SARS-CoV-2, EPA expects them to kill the virus because they demonstrate efficacy against a harder-to-kill virus or another human coronavirus similar to the one causing COVID-19.

The advisory also discusses devices that claim to kill SARS-CoV-2.  It states that a pesticidal device is an instrument or other machine that is used to destroy, repel, trap, or mitigate any pests, including viruses (i.e., ozone generators, UV lights).  EPA notes that unlike registered pesticide products, the safety and efficacy of pesticidal devices are not routinely reviewed by EPA.  EPA states that it therefore cannot confirm whether, or under what circumstances, such products might be effective against SARS-CoV-2.  The advisory states that consumers should be aware that pesticidal devices making such claims have not been reviewed and accepted by EPA.  It further states that while pesticidal device labels must have an EPA establishment number (which identifies where a product was produced), they will not have an EPA registration number because pesticidal devices are not subject to the same registration requirements as pesticides.

According to the advisory, pesticidal devices are subject to certain regulatory requirements under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), one of which is a prohibition of false or misleading labeling claims.  The advisory specifically states:

Making false or misleading labeling claims about the safety or efficacy of a pesticidal device may result in penalties under FIFRA. Please note that ozone generators, UV lights and other pesticide devices may not be able to make claims against coronavirus where devices have not been tested for efficacy or safety for use against the virus causing COVID-19 or harder-to-kill viruses. In addition, because EPA does not review these data as part of a registration review process, these claims are not supported by any government review.

Because EPA does not review or register pesticide devices, these products are not included on List N.

It is important for pesticide device producers to review carefully the data supporting the claims made for their devices to ensure that they comply with the regulatory requirements under FIFRA.

On October 13, 2017, the U.S. Environmental Protection Agency (EPA) announced that it had reached an agreement with Monsanto, BASF, and DuPont on measures “to further minimize the potential for drift to damage neighboring crops from the use of dicamba formulations used to control weeds in genetically modified cotton and soybeans,” and “new requirements for the use of dicamba ‘over the top’ (application to growing plants) will allow farmers to make informed choices for seed purchases for the 2018 growing season.”

EPA states that in a series of discussions, it “worked cooperatively with states, land-grant universities, and the pesticide manufacturers to examine the underlying causes of recent crop damage in the farm belt and southeast,” “sought extensive input from States and [U.S. Department of Agriculture (USDA)] cooperative extension agents from across the country, as well as the pesticide manufacturers, on the underlying causes of damage,” and “reviewed all available information carefully and developed tangible regulatory changes for the 2018 growing season.”

The label changes that certain registrants of dicamba products have agreed to impose additional requirements for "over the top" use of these products next year.  These new requirements include:

  • Classifying products as "restricted use," permitting only certified applicators with special training, and those under their supervision, to apply them; dicamba-specific training for all certified applicators to reinforce proper use;
  • Requiring farmers to maintain specific records regarding the use of these products to improve compliance with label restrictions;
  • Limiting applications to when maximum wind speeds are below 10 mph (from 15 mph) to reduce potential spray drift;
  • Reducing the times during the day when applications can occur;
  • Including tank clean-out language to prevent cross contamination; and
  • Enhancing susceptible crop language and recordkeeping with sensitive crop registries to increase awareness of risk to especially sensitive crops nearby. 

This announcement follows two compliance advisories issued by EPA in August 2016 and July 2017 on what EPA described as the high number of complaints received regarding crop damage from the alleged misuse of herbicides containing the active ingredient dicamaba.  EPA’s August 2016 compliance advisory stated that the Missouri Department of Agriculture received 117 complaints alleging misuse of pesticide products containing dicamba, and Missouri growers estimated that more than 42,000 acres of crops had been adversely affected.  Further, that similar complaints alleging misuse of dicamba products were received by Alabama, Arkansas, Illinois, Kentucky, Minnesota, Mississippi, North Carolina, Tennessee and Texas.  In the spring of 2016, EPA issued a proposal to register dicamba to control weeds in cotton and soybean that have been genetically engineered to tolerate dicamba.  In November 2016, EPA issued a conditional registration for dicamba on dicamba-tolerant cotton and soybean to Monsanto for its Xtendimax product; and EPA recently approved a label amendment made by Monsanto for Xtendimax which includes “additional restrictions further minimizing off-field movement of the active ingredient dicamba.”

EPA’s July 2017 compliance advisory states that by early July, EPA had received reports of hundreds of complaints to state agencies in Arkansas, Missouri, and Tennessee, a significant increase from 2016; lists the three new conditional registrations issued late last year (including Xtendimax); and states that only these new registered products may be lawfully applied over-the-top of growing soybeans and cotton.  It discusses what it describes as unlawful applications of dicamba products, and states that “[e]xcept for the new conditionally registered dicamba products, application of a dicamba product during either the cotton or soybean crop growing season is unlawful under FIFRA.”

EPA’s July 2017 compliance advisory further states that each of the conditionally approved dicamba herbicide products has labeling that provides mandatory directions for use, restrictions, and special precautions that must be followed, and that the labels of the new products require specific and rigorous drift mitigation measures to further reduce the potential for exposure from spray drift including:

  • No application from aircraft;
  • No application when wind speed is over 15 mph;
  • Application only with approved nozzles at specified pressures; and
  • Buffer zones to protect sensitive areas when the wind is blowing toward them.

Commentary

The reports of and concerns about potential damage to crops in connection with the application of dicamba illustrate a problem that has long been discussed, which is the potential for unintended impact when a pesticide that has been specifically designed for use with one or more crops that have been genetically engineered to be tolerant to the pesticide is applied in close proximity to other crops that do not share these tolerant characteristics. 

The dicamba case also illustrates the differing views on potential misuse issues.  Some observers have questioned whether all of the reported dicamba incidents were due to misuse or misapplication of the product.  Although the 2018 label changes are designed to mitigate the potential for damage to sensitive crops, some question whether some unanticipated or as yet not completely understood factor may be at play in some of the incident reports.  One issue raised by some researchers concerns potential unexpected volatility of the product even when applied according to the label directions by well-trained applicators.  The registrants have disputed this suggestion, but it is an area which will likely be more thoroughly researched over the next few growing seasons.

More information on EPA’s regulatory action on dicamba is available on EPA’s website.
