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 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 June 14, 2019, Canada’s Pest Management Regulatory Agency (PMRA) began a public consultation on Discussion Document DIS2019-01, “Consultation on Inspecting Confidential Test Data for Post-market Reviews in the Reading Room.” Before a pesticide can be registered for use in Canada, PMRA states that it reviews the available scientific test data to determine whether there are concerns for human health or safety, or the environment, when the product is used according to the label. Some of the data reviewed by the PMRA scientists include confidential test data on:
- Toxicology related to human health;
- Bystander and occupational exposure;
- Food residue trials;
- Environmental toxicology and fate;
- Product efficacy, crop tolerance, and benefits of the product; and
- Other scientific data or studies submitted to, or considered by the PMRA.
According to PMRA, the purpose of the consultation document is to seek input on a proposal to expand access to confidential test data by inviting interested members of the public to inspect these data at the proposed decision stage for post-market reviews such as re-evaluations and special reviews. Currently, PMRA prepares confidential test data for public inspection only after it makes a final decision. PMRA proposes to allow interested parties seeking to understand the scientific basis for a proposed re-evaluation or special review decision to inspect the data used by PMRA earlier in the process. PMRA states that by viewing these data earlier, comments submitted through the existing consultation process may be more well-informed.
PMRA notes that the proposed change would still require the inspection of confidential test data to take place at its National Head Office in Ottawa, Ontario. PMRA states that it is aware that this could be burdensome and is investigating alternative approaches for the future that may allow the inspection of data through other means, such as satellite reading rooms or secure portals. Publication of the consultation document began a 60-day comment period.

On May 28, 2019, the California Department of Pesticide Regulation (DPR) posted a new presentation identifying the top ten agricultural pesticide use violations of 2018. Its announcement states that “DPR suggests reviewing these common violations of pesticide laws and regulations to help ensure … compliance.” The presentation, “Top 10 Agricultural Pesticide Use Violations of 2018,” is available here. The violations are listed from the least common (number 10) to the most common (number 1):
10. Handler Training, regulated under Title 3 of the California Code of Regulations (C.C.R.) § 6724. Examples of handler training violations listed in the presentation are: not updating employee training before a new pesticide is handled; and not providing employees handler training before they work on or repair equipment previously used to apply pesticides.
9. Application-Specific Information (ASI) for Fieldworkers, regulated under 3 C.C.R. § 6761.1. Examples of violations listed in the presentation are: not including a specific description of the location of the ASI on the Pesticide Safety Information Series (PSIS) A-9 leaflet so that workers have unimpeded access; and not displaying the ASI before fieldworkers work in a treated field.
8. Hazard Communication for Fieldworkers, regulated under 3 C.C.R. § 6761. Examples of these types of violations listed in the presentation are: not retaining Safety Data Sheets (SDS) for the pesticides listed in the pesticide use records within the past two years; and not informing employees or the Farm Labor Contractor (FLC) of the location of the pesticide use records before the employees enter a treated field.
7. Handler Decontamination Facilities, regulated under 3 C.C.R. § 6734. Examples of these types of violations listed in the presentation are: not having an emergency eye flush station able to rinse the eye gently for 15 minutes at the mix and load site, when protective eyewear is required by the pesticide labeling; and handlers using hand sanitizer for decontamination instead of soap and water.
6. Availability of Labeling, regulated under 3 C.C.R. § 6602. Examples of labeling availability violations listed in the presentation are: not having relevant Special Local Needs (SLN) labeling at the site when mixing, loading, or applying; and not having the labeling booklets on-site when mixing, loading, or applying.
5. Service Container Labeling, regulated under 3 C.C.R. § 6678. Examples of service container labeling violations listed in the presentation are: not including the signal word on a service container label; and not including the address of the company or person responsible for the container on the label.
4. Annual Registration with County Agricultural Commissioner by Anyone Who Intends to Advertise, Solicit, or Operate as a Pest Control Business in California, regulated under California Food and Agriculture Code (FAC) § 11732. An example of a violation is performing pest control activities in a county before registering with the County Agricultural Commissioner (CAC).
3. Emergency Medical Care Requirements, regulated under 3 C.C.R. § 6726. Examples of violations listed in the presentation are: not taking employees suspected of a pesticide illness to the doctor immediately; and failure to post the handler emergency medical care information.
2. Personal Protective Equipment (PPE) Requirements, regulated under 3 C.C.R. § 6738. Examples of violations listed in the presentation are: storing PPE in the same place pesticides are stored; and an employer not providing the proper PPE required by the labeling.
1. Labeling and Permit Conditions Compliance, regulated under FAC § 12973. Examples of violations listed in the presentation are: not following the pesticide storage requirements listed on the labeling; and applying a pesticide to a site or crop not listed on the labeling.
Additionally, DPR has created an informative presentation about the 2019 license renewal process to help spread awareness to those renewing this year (last names and business names starting with M-Z). DPR states that it encourages continuing education (CE) sponsors, CAC staff, and others to use the presentation to inform license and certificate holders renewing this year about DPR’s renewal process, CE requirements, important dates, and the benefits of renewing early. The 2019 Renewal Process presentation is available here.

On May 21, 2019, the U.S. Environmental Protection Agency (EPA) announced that “to increase transparency and ensure information is easily accessible,” it has created a new web-based table of the most recent pesticide registration review actions that contains a list of the registration review actions EPA has taken over the current fiscal year, including the chemical name, docket number, and public comment period when applicable. EPA will update the table each time a registration review action is published. Stakeholders and the public can now quickly locate and sort through the following information for each active ingredient with a recent registration review action:
- The docket number (with a direct link to the docket);
- Comment period deadline (if applicable);
- Case number;
- Designated division;
- Registration review action type; and
- Contact information for the chemical review manager.
The new table also provides direct links to dockets, making it easy to access supporting information and documents related to a pesticide’s registration review. EPA states that it plans to update continuously this table as new registration review actions occur.

On May 3, 2019, the U.S. Environmental Protection Agency (EPA) announced it was making final a single correction to the data requirements for antimicrobial pesticide products codified in 40 C.F.R. Part 158, subpart W. 84 Fed. Reg. 18993. The correction clarifies that the 200 parts per billion (ppb) level described in the antimicrobial pesticides data requirements regulations (40 C.F.R. § 158.2230(d)) “is based on total estimated daily dietary intake for an individual and not on the amount of residue present on a single food,” as EPA states was incorrectly implied by the previous regulatory text. EPA initially proposed this change on August 18, 2017 (82 Fed. Reg. 39399) because it agreed to do so in a settlement agreement with the American Chemistry Council (ACC) after ACC filed a petition for review of the 2013 final rule titled “Data Requirements for Antimicrobial Pesticides” (78 Fed. Reg. 26936 (May 8, 2013)) in the U.S. Court of Appeals for the District of Columbia Circuit. Specifically, EPA agreed to make this correction to “make the language consistent” with the U.S. Food and Drug Administration’s (FDA) policy set forth in FDA’s “Guidance for Industry, Preparation of Food Contact Notifications for Food Contact Substances: Toxicology Recommendations. Final Guidance. April 2002.” EPA states that the change is intended to “enhance understanding of the data required to support an antimicrobial pesticide registration and does not alter the burden or costs associated with these previously promulgated requirements” and that it is not establishing “any new data requirements or any other revisions (substantive or otherwise) to existing requirements.” The final rule will become effective on July 2, 2019.
