On October 24, 2019, the U.S. Environmental Protection Agency (EPA) announced that it is proposing narrow updates to the Worker Protection Standard’s (WPS) provision on the Application Exclusion Zone (AEZ) requirements. By narrowing updates to the WPS, EPA states that it will “improve the long-term success of the agency’s Application Exclusion Zone requirements” and “would improve enforceability for state regulators and reduce regulatory burdens for farmers.” EPA believes narrowing updates to the WPS will also continue to protect the health of farm workers and other individuals near agricultural establishments who could be exposed to agricultural pesticide applications. The proposed updates are consistent with the 2019 Pesticide Registration Improvement Act (PRIA).
EPA Administrator Andrew Wheeler states that EPA’s proposal “would enhance the agency’s Application Exclusion Zone provisions by making them more effective and easier to implement.” Wheeler states that “our proposal will make targeted updates, maintaining safety requirements to protect the health of those in farm country, while providing greater flexibility for farmers.”
EPA will hold a 90-day public comment period and seeks input on select updates that were publicly suggested to EPA by both state pesticide agencies responsible for enforcing the provision and agricultural stakeholders since the AEZ requirement was adopted in 2015. The proposed updates are also consistent with the U.S. Department of Agriculture’s comments during a May 2017 meeting of EPA’s Pesticide Program Dialogue Committee.
Specifically, EPA is proposing to:
- Modify the AEZ so it is applicable and enforceable only on a farm owner’s property, where a farm owner can lawfully exercise control over employees and bystanders who could fall within the AEZ. As currently written, the off-farm aspect of this provision has proven very difficult for state regulators to enforce. These proposed changes would enhance both enforcement and implementation of the AEZ for state regulators and farm owners, respectively. Off-farm bystanders would still be protected from pesticide applications with the existing “do not contact” requirement that prohibits use in a manner that would contact unprotected individuals.
- Exempt immediate family members of farm owners from all aspects of the AEZ requirement. This will allow farm owners and their immediate family members to decide whether to stay in their homes or other enclosed structures on their property during certain pesticide applications, rather than compelling them to leave even when they feel safe remaining.
- Add clarifying language that pesticide applications that are suspended due to individuals entering an AEZ may be resumed after those individuals have left the AEZ.
- Simplify the criteria for deciding whether pesticide applications are subject to the 25- or 100-foot AEZ.
Publication of the proposed rule in the Federal Register will begin a 90-day comment period. Comments are due on or before January 30, 2020.
When EPA included the AEZ concept in its 2015 WPS updates, of chief concern for pesticide applicators, farmers, and state departments of agriculture were the compliance and enforcement practicalities of aspects of the AEZ requirements. For example, in scenarios where the AEZ extends to nearby roads and highways, it is difficult for pesticide applicators to be aware of every vehicle that may pass by that could enter the AEZ during applications. It is unclear if the revised AEZ requirements adequately address these practical realities. Agricultural stakeholders and pesticide applicators may wish to submit comments on the proposed revisions.
Additional information on the WPS is available on EPA's website.

On October 17, 2019, the U.S. Environmental Protection Agency (EPA) released the Spanish Translation Guide for Pesticide Labeling resource for use by all, including pesticide registrants that choose to display parts of their pesticide product label in Spanish. The purpose of the guide is to be a resource for the translation of the health and safety sections on pesticide labeling from English to Spanish. EPA states that the “guide is written in a universal form of Spanish to reach as many Spanish speakers as possible.”
While translating pesticide labels is not a requirement, EPA generally allows pesticide registrants to translate their product labels into any language so long as there is an EPA-accepted English version of the label and the translation is true and accurate. The guide is not intended to substitute for or eliminate the pesticide labels in English. An English version of all required labeling text is needed for all pesticide products in accordance with 40 C.F.R. Section 156.10(a)(3).
The guide provides translations for standard language typically used in the health and safety sections of pesticide product labels such as the:
- First aid and precautionary statement label language;
- Signal words;
- Misuse statements;
- Storage and pesticide container disposal instructions;
- Personal protection equipment label statements; and
- Worker Protection Standard agricultural use requirements.
EPA states that it “developed the Spanish translation guide in response to feedback from stakeholders who believe that having bilingual pesticide labeling is critical to the well-being of pesticide handlers, applicators, and farmworkers, many of whom do not speak English as a first language.”
The English statement appears in the left-hand column and the corresponding Spanish translation is available in the right-hand column of the guide. EPA states that the “guide will help registrants maintain accurate, consistent translations on product labels and ease their burden when adding Spanish translations.”

On September 30, 2019, the U.S. Environmental Protection Agency (EPA) released an updated Aquatic Life Benchmarks Table for registered pesticides. The update includes four newly registered pesticides and their degradants as well as new values for more than 30 previously registered pesticides. The benchmarks inform state and local regulators in their interpretation of water quality monitoring data. Waterbodies where benchmarks are exceeded may be prioritized for further investigation. EPA derived the latest updates from toxicity values from the most recent ecological risk assessments for the registered pesticides as part of the regular registration review. EPA aims to update the table on an annual basis. The full table and links to source documents for each of the benchmarks are accessible on EPA’s website here.

On September 17, 2019, the European Food Safety Authority (EFSA) opened a consultation period on two pilot assessments of the risks posed to humans by residues of multiple pesticides in food. EFSA is seeking comments from interested parties on the assessments. The first assessment considers the chronic effects of multiple pesticides on the thyroid system. The second looks at acute effects on the nervous system.
EFSA produced the assessments in collaboration with the National Institute for Public Health and the Environment for the Netherlands (RIVM) using monitoring data from 2014, 2015, and 2016. In approving pesticides for use in the European Union (EU), EFSA establishes a maximum level of pesticide residue (MRL) allowed in food or animal feed. The MRL considers the cumulative effects of pesticides. Pesticides may only be placed on the EU market if they have no harmful effects on humans, including cumulative effects. In the two pilot assessments, EFSA classified pesticides into “cumulative assessment groups” (CAG) based upon whether they produce similar toxic effects in a specific organ or system. EFSA states that “[t]he overall draft conclusion for both assessments is that consumer risk from dietary cumulative exposure is below the threshold that triggers regulatory action for all the population groups covered.”
In 2020, EFSA will prepare the assessments in final, which will serve to “inform risk managers in the European Commission and Member States who regulate the safe use of pesticides in the EU.”
EFSA will present the assessments at a special stakeholder event in Brussels, Belgium, on October 22, 2019. The meeting is intended to allow stakeholders with expertise and interest in the area to discuss the technical issues relating to the draft assessments. Registration for the meeting closes on October 11, 2019.
All comments must be submitted by November 15, 2019. Comments on the “Cumulative dietary risk characterisation of pesticides that have chronic effects on the thyroid” may be submitted at https://ec.europa.eu/eusurvey/runner/PC_CRA_Thyroid_Sept-2019. Comments on the “Cumulative dietary risk characterisation of pesticides that have acute effects on the nervous system” may be submitted at https://ec.europa.eu/eusurvey/runner/PC_CRA_Nerv_Syst_Sept-2019.
The two draft assessments are available on EFSA’s website.

On October 1, 2019, the U.S. Environmental Protection Agency (EPA) issued a Federal Register notice announcing the that fees under the Pesticide Registration Improvement Extension Act of 2018 (PRIA 4) were increased by five percent for pesticide applications received on or after October 1, 2019. The five percent increase is on fee amounts established by Public Law 116-8, which became effective on March 8, 2019. The revised fees will remain in effect until September 30, 2021.
The fee schedule provided in PRIA 4 identifies the registration service fees and decision times organized according to the organizational units of the Office of Pesticide Programs (OPP) within EPA. EPA presents the schedules as 19 tables, organized by OPP Division and by type of application or pesticide subject to the fee, and lists the registration service fee for actions received in fiscal years 2020 and 2021. Applicants must submit fee payments at the time of application. EPA will reject any application that does not contain evidence that the PRIA 4 fee has been paid.
The revised fee schedule for PRIA 4 fiscal years 2020 and 2021 is available on EPA’s website. More information on the PRIA 4 legislation is available on our blog under key word PRIA.

On September 24, 2019, the U.S. Environmental Protection Agency (EPA) announced the availability of the premises treatment final test guideline, under Series 810, Product Performance Test Guidelines. The guideline, 810.3500 Premise Treatment, provides recommendations on how to conduct efficacy testing against invertebrate pests in premises, such as cockroaches, ticks, mosquitoes, flies and wasps in connection with registration of pesticide products for use against public health pests. This guideline does not, however, apply to efficacy testing for treatment of livestock or pets, wide-area mosquito control, structural protection from termites, or bed bug products.
EPA states that “The final guideline clarifies the original guideline published in 1998 based on public comments and recommendations from the Federal Insecticide, Fungicide, and Rodenticide Act Scientific Advisory Panel (FIFRA SAP).”
Revisions to 810.3500 include
- Clarifying bait product testing;
- Offering more flexibility in testing design;
- Updating the replication recommendations based on statistical modeling and ease of obtaining pests; and
- Refining the statistical analyses recommendations.
Documents pertaining to the revision of the product performance guidelines, including public comment submissions, and the agency’s response to comments are available at www.regulations.gov in Docket Number EPA-HQ-OPP-2017-0693. More information on test guidelines is available on our blog.

On September 9, 2019, the U.S. Environmental Protection Agency (EPA) Office of Pesticide Programs (OPP) published a notice in the Federal Register announcing the availability of, and an opportunity for comment on, a document describing an “interim process” that OPP’s Environmental Fate and Ecological Effects Division is currently using to evaluate potential synergistic effects of mixtures of pesticide active ingredients on non-target organisms. As part of a lawsuit challenging the 2012 decision by EPA to register Enlist Duo Herbicide (a combination of 2,4-D and glyphosate), OPP scientists learned that patent applications for some registered pesticide products included claims that particular combinations of active ingredients provide “synergistic” control of target species. Although EPA was not at that time considering potential synergies in assessing the risk for ecological effects on non-target organisms, based on the patent application claims regarding synergy for Enlist Duo, EPA decided to request that the reviewing court vacate its registration decision and remand the application for Enlist Duo for further study of these effects and any measures that might be needed to mitigate the risk to non-target organisms. This decision sparked much controversy, and many in industry were concerned that patent application claims were not being correctly interpreted by EPA for the category of pesticide products at issue.
The new document released by EPA for review and comments is entitled: “Process for Receiving and Evaluating Data Supporting Assertions of Greater Than Additive (GTA) Effects in Mixtures of Pesticide Active Ingredients and Associated Guidance for Registrants.” EPA states that it “has generally been applying this interim process since 2016.” The process described in the document has five steps: (1) registration applicants must search for any granted patents that include synergy (GTA) claims for combinations of pesticides; (2) applicants must review the patent claims and supporting data for relevance to ecological risk assessment; (3) applicants must report to EPA all effects testing data from the relevant patents; (4) applicants must do a statistical analysis (using a method prescribed by EPA) to determine whether any observations of GTA effects are statistically significant; and (5) EPA will review all submitted information to decide whether it should be utilized in ecological risk assessment.
In the Federal Register notice, OPP lists five specific areas pertaining to the interim risk assessment process described in the document on which it is requesting comment:
- Are there technical aspects of the interim process that warrant change? If so, what changes are recommended?
- What aspects of the process could be applied to the evaluation of open literature sources of GTA effects pesticide interactions?
- Should EPA consider standardizing a more detailed search and reporting approach, and how should EPA do that?
- Should EPA continue the evaluation process as described in this document? If so, what performance metrics (e.g., number of evaluations) should EPA consider before deciding the utility of this approach?
- What applicant burden is associated with the activities described in this memorandum, including compiling, analyzing, and submitting the information? Specifically, does an estimate of 80-240 hours of burden per applicant cover the respondent burden associated with the interim process?
When the National Research Council (NRC) evaluated the importance of toxicological interactions between pesticide active ingredients in 2013, the NRC concluded that such interactions are rare, but that EPA should nonetheless consider such interactions when the best available scientific evidence supports such an evaluation. In the current Federal Register notice, EPA makes it clear that it is uncertain concerning the utility for risk assessment of the information used by manufacturers to support synergistic effects claims in pesticide patents. According to EPA, 24 applicants for new registrations have submitted patent data to date, but only three of these submissions contained information that indicated a need for further testing and no submission ultimately led to any adjustment of the ecological risk assessment. At this juncture, EPA will continue collecting patent data that may be pertinent to GTA effects, but when it has sufficient experience upon to base a general policy it may either continue or improve this process or discontinue it after explaining why.
When EPA requested that the reviewing court vacate and remand the registration EPA had granted for Enlist Duo, the parties seeking judicial review located data in the patent applications that EPA had not previously seen or reviewed and that EPA believed could possibly be pertinent to potential adverse effects on non-target plants. EPA concluded that it should revisit the decision based on the additional data. Although EPA decided to request vacatur and remand, the applicant Dow AgroSciences had arguably followed all of the procedures then in place, because FIFRA Section 3(c)(5) allows EPA to waive data requirements pertaining to efficacy, and EPA typically registers pesticide product that are not intended to protect public health without any independent evaluation of efficacy data. Nevertheless, in general EPA may choose to evaluate pesticidal efficacy data; such circumstances in the past often involved cases where EPA was required to consider whether pesticide benefits are sufficient to outweigh identified risks. In the Enlist case, EPA determined that it should do so where potential synergy in pesticidal efficacy is pertinent to evaluating ecological effects on non-target species.
What EPA must decide now is how often efficacy data that has been deemed adequate by the Patent and Trademark Office to support a patent for a new pesticide mixture will have any material significance in the context of ecological risk assessment. Before EPA makes a determination whether or not patent data has sufficient pertinence to continue requiring routine collection and evaluation of such data, EPA has decided it is prudent to afford all stakeholders an opportunity to comment on whether EPA has been asking the right questions.
All comments on the draft document must be submitted no later than October 24, 2019.

On September 4, 2019, the U.S. Environmental Protection Agency’s (EPA) Office of Pesticide Programs’ Environmental Fate and Effects Division (EFED) announced that the next Environmental Modeling Public Meeting (EMPM) will be held on October 16, 2019. The EMPM is a semi-annual public forum for EPA, pesticide registrants, and other stakeholders to discuss current issues related to modeling pesticide fate, transport, and exposure for risk assessments in a regulatory context.
In a press release to the public, EPA indicates that the topics covered at the October meeting will include sources of usage data (relating to the actual application of pesticides, in terms of the quantity applied or units treated); spatial applications of usage data; model parameterization; extrapolation of usage data to fill in gaps; temporal variability of usage; and updates on ongoing topics. Presentations concerning the incorporation of pesticide usage data into environmental exposure and ecological risk assessments will also be included.
Registration is required. Requests to participate in the meeting must be received on or before September 23, 2019, as noted in the Federal Register notice.

On August 23, 2019, the U.S. Environmental Protection Agency (EPA) issued a Federal Register notice announcing the receipt of 10 applications to amend currently registered pesticide products to add hemp as a new use site. The 10 application amendments are the result of the 2018 Farm Bill, signed in to law on December 20, 2018, that removed hemp from the Controlled Substances Act and legalized commercial use and production of hemp that contains less than 0.3% tetrahydrocannabinol (THC).
EPA states in the notice that Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) Section 3(c)(4) does not require EPA to provide notice and opportunity to comment concerning these 10 applications because hemp falls within the terrestrial outdoor and residential outdoor use pattern previously approved for the pesticidal active ingredients in question, and approval of the applications would therefore not involve "a changed use pattern." Instead, EPA states that it has decided to provide an opportunity to comment in this instance "because of the potential significant interest from the public" and to be "completely transparent about these applications." EPA also states that it does not intend to provide notice or opportunity to comment for similar applications to add hemp that are likely to be submitted in the future.
EPA also states that the products with requested label amendments contain active ingredients for which EPA "has previously determined the residues will be safe under any reasonably foreseeable circumstances." Each active ingredient has an established tolerance exemption for residues on all raw agricultural or food commodities.
The 10 products for which EPA has received an application to add hemp are:
- Debug Turbo, EPA Registration No. 70310-5, active ingredients: azadirachtin and neem oil;
- Debug Optimo, EPA Registration No. 70310-7, active ingredients: azadirachtin and neem oil;
- Debug Trés, EPA Registration No. 70310-8, active ingredients: azadirachtin and neem oil;
- Debug-ON, EPA Registration No. 70310-11, active ingredient: neem oil;
- REGALIA Bioprotectant Concentrate, EPA Registration No. 84059-3, active ingredient: extract of Reynoutria sachalinensis;
- MBI-110 EP, EPA Registration No. 84059-28, active ingredient: Bacillus amyloliquefaciens strain F727;
- GH CMT, EPA Registration No. 91865-1, active ingredients: soybean oil, garlic, oil, and capsicum oleoresin extract;
- GH MPMT, EPA Registration No. 91865-2, active ingredient: potassium salts of fatty acids;
- GH DNMT, EPA Registration No. 91865-3, active ingredient: Bacillus amyloliquefaciens strain D747; and
- GH NAMT, EPA Registration No. 91865-4, active ingredient: azadirachtin.
Once public comments are received, EPA anticipates making its decision on adding hemp as a new use site on the specific products before the end of 2019, so that these products may be available for the 2020 growing season.
Although the Federal government has legalized commercial production and use of hemp (as opposed to marijuana that contains higher levels of THC), not every State has changed its laws to conform to the new classification. EPA took the unusual step of announcing receipt of the new amendment applications at Hemp Production Field Day at the University of Kentucky. Senator Rand Paul of Kentucky has long been a proponent of commercial hemp production, and about 1,000 growers in Kentucky now have licenses to grow hemp for commercial use.
As hemp production increases, there will also be increased demand for pesticides to combat weeds, insects, and plant diseases that pose a potential threat to this crop. Although hemp fiber and oil have many potential industrial uses, hemp also has potential medicinal uses because extracts containing cannabidiol (CBD) are now being widely marketed for their purported health benefits. This use of hemp means that EPA will have to consider whether new tolerances may be required for some active ingredients before they can applied to hemp. As EPA has noted, the active ingredients in the 10 products for which EPA announced that applications are pending to add labeling for hemp already have tolerance exemptions, and therefore do not present this issue.
Comments are due on or before September 23, 2019. The public can submit comments at www.regulations.gov in Docket Number EPA-HQ-OPP-2019-0369.

On August 13, 2019, the U.S. Environmental Protection Agency (EPA) published a notice in the Federal Register announcing a four-day meeting of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) Scientific Advisory Panel (SAP) will be held November 19-22, 2019. The meeting location will be announced in the future on the FIFRA SAP website. The title of the SAP meeting is “Approaches for Quantitative Use of Surface Water Monitoring Data in Pesticide Drinking Water Assessments.” Pesticide registrants have long advocated for the opportunity to use monitoring data in drinking water assessments in place of estimates generated using current modeling approaches. It is expected that EPA will present work that the Environmental Fate and Effects Division (EFED) has completed to permit use of surface water monitoring data.
The Federal Register Notice also requests nominations for ad hoc reviewers with particular expertise related to the particular issues to be addressed by this panel. Nominations are to be submitted on or before September 12, 2019.
