On May 25, 2022, the California Department of Pesticide Regulation (DPR) announced that it will hold three public workshops to collect feedback on the next phase of design and development for DPR’s pesticide application notification system.
DPR states that the workshops will be hosted online via Zoom and facilitated by the UC Davis Center for Regional Change. Each workshop will follow the same format, including a brief overview of the proposed design for the statewide notification system and an opportunity for the public to provide input.
DPR began developing the statewide notification system in mid-2021, after the state budget allocated $10 million to DPR for system development. DPR designed the proposed system based in part on feedback from stakeholders during public focus groups and webinars. DPR states it will use the information collected during the forthcoming workshops for the next design phase of the statewide notification system.
DPR states on its website that “the tool will advance environmental justice and further protect public health by providing transparent and equitable access to information in advance of pesticide applications occurring near where people live, work or play.” DPR states further “That information will provide the public with the opportunity to make their own decisions about any additional precautions they may want to take to protect their health.”
The dates and times of the workshops are:
DPR states that registration is not required to attend. The workshops will be hosted online via Zoom. The Zoom link for each workshop is provided above on each date and time. Spanish interpretation will be provided at all workshops. A copy of materials presented during the workshops will be made available on DPR’s website following the workshops.
DPR states in its FAQs that it anticipates implementation for the system to occur in 2024. DPR states for more information and updates on statewide notification, please visit its website.
Registrants should monitor developments closely.

As reported in our November 2, 2020, blog item, on October 30, 2020, the U.S. Environmental Protection Agency (EPA) issued a final rule on the Agricultural Worker Protection Standard (WPS) regulation that revises the requirements on the pesticide application exclusion zone (AEZ), defined as an “area surrounding the point(s) of pesticide discharge from the application equipment that must generally be free of all persons during pesticide applications.” The final AEZ requirements were scheduled to go into effect on December 29, 2020, but on December 28, 2020, the U.S. District Court for the Southern District of New York issued an order in the case of State of New York et al. v. EPA that resulted in a stay of the requirements. Subsequent orders have extended this stay of the effectiveness.
EPA published a May 16, 2022, Federal Register notice stating that as of February 15, 2022, the effectiveness of the WPS final rule is stayed by court order until August 22, 2022. 87 Fed. Reg. 29673. According to the notice, EPA intends to publish another document in the Federal Register to address the status of the 2020 final rule if the stay of effectiveness expires or is lifted, but EPA “does not intend to publish additional Federal Register documents to announce any additional court orders entered to further stay the effectiveness of the 2020 final rule.”

On May 6, 2022, the U.S. Environmental Protection Agency (EPA) published a notice in the Federal Register announcing the availability of, and requesting comments on, data related to aquatic toxicity of chitosan salts. 87 Fed. Reg. 27059. Specifically, EPA is seeking comments on the following two aquatic toxicity reports submitted by Tidal Vision Products, LLC (Tidal Vision), the company that submitted a petition to EPA on October 10, 2018, requesting that EPA add chitosan to the list of active ingredients eligible for EPA’s minimum risk pesticide exemption under Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) Section 25(b):
- Tidal Vision USA. (2019). Aquatic Toxicology Report by Eurofins Environmental Testing Test America. Lab I.D. No. B4345. Report Date: June 17, 2019. EPA Master Record Identification (MRID) 51861901.
- Tidal Vision USA. (2019). Aquatic Toxicology Report by Eurofins Environmental Testing Test America. Lab I.D. No. B4421. Report Date: August 28, 2019. EPA Master Record Identification (MRID) 51861902.
EPA is seeking input on how these reports may be used by EPA in its assessment of aquatic toxicity of chitosan and its salts. EPA states “chitosan may form as a salt (e.g., acetate, lactate, hydrochloride, and salicylate) when it is solubilized in acids for end use product formulation and subsequently applied in the environment” and the new information submitted by Tidal Vision pertains to these salts. Comments on the aquatic toxicity reports are due on or before June 6, 2022, in Docket EPA-HQ-OPP-2019-0701.
As background, EPA on August 20, 2020, announced that it was seeking to add chitosan to the list of active ingredients allowed in minimum risk pesticides that are exempt from pesticide registration requirements and was providing to the United States Department of Agriculture (USDA) for review a draft regulatory document titled ‘‘Pesticides; Addition of Chitosan to the List of Active Ingredients Allowed in Exempted Minimum Risk Pesticides Products.” A minimum risk product must meet six specific conditions to be exempt from pesticide registration. One of those conditions is that the active ingredient in the minimum risk pesticide be one that is listed specifically by EPA. If EPA adds chitosan to the list of minimum risk pesticide active ingredients, pesticide products containing chitosan could qualify as minimum risk pesticides provided the other conditions also are satisfied (e.g., using inert ingredients approved by EPA for use in minimum risk pesticides, not making any public health claims).
On November 2, 2020, EPA requested comments on the proposed rule to add chitosan to the list of active ingredients eligible for the exemption. In the May 6, 2022, Notice, EPA states that comments received on the proposed rule expressed concerns regarding derivatives of chitosan that are likely to be produced when chitosan is mixed with certain acids and on the potential hazard for aquatic organisms exposed to chitosan salts. Because of the concerns raised, EPA now is requesting comments on the two aquatic toxicity reports that pertain to these salts.
EPA continues to remain focused on listing this specific substance rather than address other issues related to minimum risk pesticides that have been raised by industry to EPA over many years. There is, for example, a petition filed in 2006 by the Consumer Specialty Products Association (CSPA) requesting that EPA modify the minimum risk pesticide regulations to exclude products claiming to control public health pests from the Section 25(b) exemption. Comments submitted in response to the November 2, 2020, proposed rule raise additional concerns, including but not limited to the fact that the vast majority of states now require registration of minimum risk pesticides, thus shifting the burden away from EPA with costly and potential inconsistent results.
Though this EPA list is called “minimum risk,” it more accurately could be described as -- “so safe no one could, or at least should, have any concern about toxicity.” There is long-standing reluctance for EPA to call any pesticide whatsoever as “safe” for various reasons, even to the point of an outright prohibition on using the word “safe” on registered labels. (This is the clever distinction that “minimum risk” pesticides do meet the FIFRA definition of a pesticide, but the Section 25(b) designation allows that the label not be subject to EPA review and registration of the label.)
This issue of possible risks from adding chitosan to the Section 25(b) list in light of the studies EPA seeks comment on appears to allow EPA to back away from its intended designation as minimum risk or to have the public comment reaffirm EPA’s assessment that chitosan’s safety profile is sufficiently beyond reproach to align with the other members of this category. There are many other pesticides considered of very low risk but not so low as to have made the Section 25(b) list until now. That there is a hint of debate about possible toxicity could signal that future additions to the list are being contemplated to encourage more “minimum risk” product development. Or more simply, it may signal EPA’s reaction to the comments received has triggered some reconsideration of how “minimum” any minimum risk needs to be to qualify for the Section 25(b) list.

According to a May 9, 2022, news item published by the U.S. Environmental Protection Agency (EPA), “Advancing EPA’s Understanding of the Next Generation of Pesticides,” over the past decade, EPA “has received an increasing number of pesticide product applications that potentially contain nanomaterials.” The article notes that EPA’s current pesticide review method was not designed for nanomaterials, so each product is reviewed on a case-by-case basis. An EPA research team led by EPA scientist Dr. Chunming Su conducted an exhaustive search for patents and published literature related to nanopesticides to understand the state of the science. The item states that the team found and analyzed more than 36,000 patents and 500 peer-reviewed journal articles. The team established two general categories of nanopesticides to help inform EPA’s regulatory reviews: products with mostly metal-based nanomaterials as the active ingredient, like nanosilver and nanocopper oxide/hydroxide; and products that encapsulate and carry the active ingredient using nanomaterials (mostly carbon based) like graphene and carbon nanotubes. According to the item, the research team also developed a review framework “that includes a simple decision tree to determine what products should be classified and evaluated as a nanopesticide.” Products determined to contain nanomaterials are subject to additional assessment or data needs from the manufacturer. Dr. Andrew Byro of EPA’s Office of Pesticide Programs (OPP) states that the framework “represents a major steppingstone in the development of a method for identification of nanomaterials.” EPA will use this framework as a platform to help inform its data needs and future determinations regarding the evaluation of nanomaterials in antimicrobial pesticides.
EPA’s research team collected their findings related to the physical and chemical properties and efficacy of nanopesticides in a peer-reviewed journal article in Nature Nanotechnology, “Nano-enabled pesticides for sustainable agriculture and global food security.” According to EPA’s news item, the team “found that nano-enabled pesticides adhere better to plant surfaces and have a reduced impact on non-target organisms. Nanopesticides may also enhance plant resilience against stressors from heat or drought.” EPA states that these benefits “could lead to higher crop yield and provide more agricultural resilience to address climate change and weather extremes.” EPA notes that the research team’s findings “also highlight the data gaps and the need for additional research on potential adverse impacts of nanopesticides.”

A circular economy requires new thinking about what products we make, from which materials we make them, and where products go at the end of their useful life. An important but often overlooked aspect of new product development is an understanding of the consequences of the product’s chemical composition and the end-of-life implications of the decisions made at the front end of the process. Working within this framework plays a critical role in building a resilient, dependable, and sustainable system that fosters innovation to develop a circular economy. Register now to join Lynn L.

On April 15, 2022, the U.S. Environmental Protection Agency (EPA) announced final product performance data requirements for products claiming efficacy against certain pests. 87 Fed. Reg. 22464. This action officially incorporates EPA’s already existing product performance standards requirements for certain invertebrate pests into the Code of Federal Regulations (CFR). EPA states this action also increases the efficiency of its approval process and will save registrants time and money.
Product performance standards are intended to make it easier for pesticide registrants to know the efficacy data that EPA requires to demonstrate that a pesticide product works as claimed. By adding these requirements into the CFR, EPA states that it intends to help ensure that submitted data meet EPA’s needs and scientific standards and satisfy a requirement of the 2018 Pesticide Registration Improvement Extension Act (PRIA 4). EPA notes as part of the agreement between pesticide stakeholders and public interest groups reflecting the environmental and farmworker safety communities in the development of PRIA, “PRIA 4 specifically establishes a new maintenance fee set-aside of up to $500,000/year to develop and finalize rulemaking and guidance for product performance data requirements for certain invertebrate pests of significant public health or economic importance. Specific to this rule, PRIA 4 requires EPA to finalize product performance data requirements by September 30, 2021, for certain pesticides intended for preventing, destroying, repelling, or mitigating specified invertebrate pest of significant public health or economic importance.”
This final rule includes product performance data requirements for the categories of invertebrate pests specified in PRIA 4, which EPA states it intends to satisfy the rulemaking requirement. EPA notes that this final rule covers some invertebrate pests in addition to those specified in PRIA 4 due to their public health, economic, or ecological significance (e.g., wood destroying insects).
EPA states that it believes this final rule will save registrants approximately $17,000 per data package submitted to EPA by reducing waste and unnecessary testing, and believes it will reduce burden hours by 4,683 annually, including 4,515 hours from reduced paperwork burden associated with data generation and 168 hours from reduced paperwork with the application process.
This final rule codifies product performance data requirements to support registration of products claiming efficacy against three categories of invertebrate pests:
- Those identified to be of significant public health importance (e.g., ticks, mosquitoes, cockroaches);
- Wood-destroying insects (e.g., termites); and
- Certain invasive invertebrate species (e.g., Asian long-horned beetle).
EPA states that the latter two categories are pests considered to be of significant economic or ecological importance.
The final rule is effective on June 14, 2022.
Codifying the product performance data requirements for invertebrate pests should increase transparency to registrants regarding the efficacy data that they typically would need to generate and submit for products to make labeling claims against these specific pests. Registrants of the products at issue should monitor these requirements closely.

On February 25, 2022, the U.S. Environmental Protection Agency (EPA) announced it has issued a response denying the objections filed against its final rule revoking all chlorpyrifos tolerances (Response). EPA issued the August 18, 2021, final rule in response to the Ninth Circuit Court’s Order directing EPA to issue a final rule in response to Pesticide Action Network North America and Natural Resources Defense Council’s 2007 petition, which requested EPA to revoke all chlorpyrifos tolerances.
After issuing the August 2021 final rule, and consistent with the Federal Food, Drug, and Cosmetic Act (FFDCA), EPA provided an opportunity for any interested party to file an objection to any aspect of the final rule and request a hearing on those objections. Several objections were filed, with concerns ranging from the scope of the revocation of tolerances, the economic and environmental impacts of the revocation, and the implementation timeframe. EPA stated that after careful consideration, it denied all objections, hearing requests, and requests to stay the final rule filed during the period for submitting responses to the final rule.
In addition to its Response, EPA issued letters to the registrants of chlorpyrifos products with food uses confirming revocation of the tolerances and providing options for cancellation and label amendments. In particular, these options include the ability for registrants to submit registration amendments to remove food uses from product labels or submit a voluntary cancellation for products where all uses are subject to the tolerance revocation. For registrations not voluntarily cancelled, EPA stated it intends to issue a Notice of Intent to Cancel under the Federal Insecticide, Fungicide, and Rodenticide Act to cancel registered food uses of chlorpyrifos associated with the revoked tolerances. A copy of its Response and the accompanying order in the chlorpyrifos final rule docket is available at EPA-HQ-OPP-2021-0523.
EPA states that this action will be incorporated into the ongoing registration review of chlorpyrifos and it will continue to review the comments submitted on the chlorpyrifos Proposed Interim Decision, draft Revised Human Health Risk Assessment, and draft Ecological Risk Assessment. These documents are available in the chlorpyrifos registration review docket at EPA-HQ-OPP-2008-0850. After considering public comments, EPA will proceed with registration review for the remaining non-food uses.
Additional information on chlorpyrifos is available on our blog and on EPA’s website.
It is not surprising that EPA denied all objections to its tolerance revocation decision. Since the earlier decision in 2009 to revoke the tolerances for the insecticide carbofuran, EPA, along with advocates of greater restrictions on pesticide exposures, have found a pathway for terminating pesticide uses while avoiding the significant procedural requirements of FIFRA’s cancellation provisions. The elaborate legal niceties of either approach will likely not quiet those grower groups and others who challenged EPA’s decision in this case.
Of note, in its lengthy Response (51 pages in the Federal Register, 87 Fed. Reg. 11222 (Feb. 28, 2022)), EPA again admits that some uses of chlorpyrifos on certain crops in certain areas are “high benefit” uses that can meet the required safety standards even when using EPA’s most conservative assumptions. Those eleven crop uses were among the many additional uses of the insecticide, and here EPA is explaining its case that as part of its decision, all of the uses on the current label are to be assessed together. At the point in time when EPA most recently assessed chlorpyrifos uses (the 2020 registration review Pesticide Interim Decision), some uses may have been able to meet the standard, but as explained in this notice: “In the final rule, EPA assessed aggregate exposure based on all currently registered uses of chlorpyrifos as required by the FFDCA and consistent with its guidance.”
This will likely be of little satisfaction to growers who produce those crops identified by EPA as meeting the standard.
To affected growers, the revocation of tolerances for the identified crop uses that nonetheless could meet the standard, along with the long-winded denial of objections citing the fine points of the legal procedures, amount -- to them -- as what Justice Scalia once described as “pure applesauce.” (Ironically, according to EPA’s 2020 assessment, applesauce sourced from New York and Michigan apples would have met the required standards according to EPA’s 2020 risk assessment.) Those groups may decide to continue the legal back-and-forth process for further review of the original decision and now the objection denials.
But the larger question for all registrants and pesticide users, not just chlorpyrifos, is what longer term issues are raised by EPA’s approach.
Bergeson & Campbell, P.C.’s (B&C®) January 26, 2022, webinar “What to Expect in Chemicals in 2022” is now available for on-demand viewing at https://attendee.gotowebinar.com/recording/864194569862780944. During the 1-hour webinar, Lynn L. Bergeson, Managing Partner, B&C; Richard E. Engler, Ph.D., Director of Chemistry, B&C; and James V. Aidala, Senior Government Affairs Consultant, B&C offered their best informed judgment as to the trends and key developments chemical industry stakeholders should expect to see from the U.S. Environmental Protection Agency (EPA) in 2022.
Momentous changes initiated in 2021 will continue to influence policy development and rulemakings in 2022. For EPA’s Office of Chemical Safety and Pollution Prevention (OCSPP), emphasis on science integrity, reviewing decisions made by the Trump Administration in both the pesticide and industrial chemicals programs, meeting statutory deadlines looming over the work of both programs, and dealing with the constant problem of EPA-wide competing priorities will drive the OCSPP program budget and regulatory priorities. We encourage you to view the webinar and read our comprehensive Forecast for U.S. Federal and International Chemical Regulatory Policy 2022 to learn more about these competing priorities for which companies should now prepare.

On January 20, 2022, the U.S. Environmental Protection Agency (EPA) announced it is extending supply-chain flexibilities for registrants of certain conventional and biopesticide products to alleviate a supply-chain issue facing the pesticide industry.
This is an extension of EPA’s July 2, 2021, action when EPA implemented supply-chain flexibilities that allowed registrants to substitute a combination of pre-approved alternate inert ingredients for inert ingredients derived from propylene oxide (PO) feedstocks. This was intended to address the limited supply of PO feedstocks due to weather events that occurred in the U.S. Gulf Coast in February 2021. This action was originally set to expire on December 31, 2021, but EPA has extended these supply-chain flexibilities until December 31, 2022, due to continued disruptions to production.
EPA emphasized in its initial July 2021 action that this relates only to non-antimicrobial pesticide products and that EPA will handle “not in-kind” substitutions for antimicrobial pesticide products on a case-by-case basis.
The pre-approved alternates for propylene glycol, a derivative of PO feedstocks, include:
- glycerin (Chemical Abstracts Service Registry Number (CAS RN) 56-81-5);
- diethylene glycol (CAS RN 111-46-6);
- ethylene glycol (CAS RN 107-21-1); and/or
- 1,3-propanediol (CAS RN 504-63-2).
These substitutions can be added to a product formulation or a brand name mixture.
Registrants must self-certify that the substitute inert ingredients will:
- Serve the same function in the product as propylene glycol;
- Maintain the validity of product-specific data submitted in support of the registration;
- Maintain the product’s acute toxicity category and physical/chemical characteristics such that no label modifications are required; and
- Maintain the product’s fitness for its intended purposes in terms of efficacy, phytotoxicity, and any other factor.
EPA states that any registrants that wish to make the substitution permanent will have to go through the standard amendment process outlined in Pesticide Registration Notice (PRN) 98-10.
Supply-chain issues have become a national concern whether one is shopping for furniture or manufacturing pesticides. The Biden Administration across government agencies and programs has sought ways to ease difficulties as part of a national response to economic disruptions caused by the COVID-19 pandemic. Pesticide ingredients may not be subject to as much media coverage as consumer products, but in the end, could have impacts affecting availability of disinfectants and other pesticide products. In the broader economy, supply-chain issues have been identified as a factor affecting the availability of pesticides used to help meet the food and fiber production needs of the nation, along with concerns about freight capacity limiting the normal distribution of crop inputs and ultimately affecting the movement of finished crops.
