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.

On July 2, 2021, the U.S. Environmental Protection Agency (EPA) announced it is taking action to alleviate a supply-chain issue facing the pesticide industry. EPA stated that it is allowing registrants of non-antimicrobial pesticide products to substitute some combination of pre-approved alternate inert ingredients for inert ingredients derived from propylene oxide feedstocks that are in limited supply due to weather events that occurred in the U.S. Gulf Coast area in February 2021. EPA stated that it is allowing these substitutions even in cases where propylene glycol is added to the formulation or is part of a brand-name mixture in which the full composition is known to the registrant.
The pre-approved alternates are 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 1,3-propanediol (CAS RN 504-63-2).
EPA emphasizes that this action, known as “Propylene Glycol Phase 2 -- ‘Not In-Kind’ Substitution Mechanism,” 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.
In April 2021, EPA implemented “Propylene Glycol Phase 1 -- ‘In-Kind’ Substitution Mechanism” to allow certain in-kind substitutions to address propylene glycol supply-chain shortages.
These actions require registrants to self-certify that the substitute inert ingredients serve the same function in the product as propylene glycol and that the change will not impact either the validity of any product-specific data submitted in support of the registration or the product’s acute toxicity category or physical/chemical characteristics in a way that would require label modifications. Registrants must also certify that the substitution will not affect the product’s fitness for its intended purposes in terms of efficacy, phytotoxicity, or any other factor.
This action is time limited, extending to December 31, 2021. Any registrants who wish to make the substitution permanent will have to go through the standard amendment process outlined in Pesticide Registration Notice (PRN) 98-10.

On November 4, 2020, the U.S. Environmental Protection Agency (EPA) published a notice in the Federal Register announcing the release of an updated list of pests of significant health importance for public review and comment. 85 Fed. Reg. 70146.
EPA, in coordination with the Centers for Disease Control and Prevention (CDC) and the U.S. Department of Agriculture (USDA), identifies pests of significant public health importance, and in coordination with the Public Health Service, develops and implements programs to improve and facilitate the safe and necessary use of chemical, biological, and other methods to combat and control such pests of public health importance. According to EPA, the list serves as a tool for private and public organizations, including local or state governments, departments of public health, pesticide registrants, and non-governmental organizations, when making decisions and plans about future public health actions.
Since this list’s original publication in 2002, new vector-borne diseases have been identified and pests that had been previously thought of as benign or nuisance pests have been found to impact adversely public health. EPA, CDC, and USDA collaborated to update the list to incorporate significant changes regarding vector-borne diseases and related research, and eliminate gaps or ambiguities in the current pests list.
EPA states in the notice that the draft Pesticide Registration (PR) Notice 2020-X more precisely describes both the pests and expected public health impacts and adds several new pests (the brown dog tick) and public health impacts (Zika fever and coronaviruses like SARS-CoV-2) and that other pests have been renamed or grouped with similar species or removed altogether (hobo spider).
Draft PR Notice 2020-X describes the groups of pests and their potential impact on public health as follows:
- Arthropods: The listed arthropods may cause asthma or trigger allergies, contaminate food, irritate skin, cause direct injury, or carry diseases such as epidemic typhus, trench fever, epidemic relapsing fever, malaria, encephalitis (St. Louis, Eastern, Western, West Nile, and LaCrosse), yellow fever, dengue fever, and many others.
- Vertebrates: The listed organisms have the potential for direct human injury and can act as disease reservoirs for rabies and other diseases. The rats and mice include those that spread rodent-borne diseases and contaminate food for human consumption.
- Microorganisms and acellular particles: This category includes listed bacteria, fungi, protozoans, viruses, virusoids, and prions. The microorganisms and acellular particles listed in this category cause diseases such as COVID-19, cholera, meningitis, Legionnaire’s Disease, and many others.
The complete list of pests is identified in draft PR Notice 2020-X in Appendix A.
EPA states that the list does not affect the regulatory status of any registration or application for registration of any pesticide product.
Comments on the draft PR Notice are due on or before January 4, 2021, in Docket EPA-HQ-OPP-2020-0260.

On May 15, 2020, the U.S. Environmental Protection Agency (EPA) announced that it is issuing its third temporary modification to Pesticide Registration (PR) Notice 98-10 to include food-contact surface sanitizer products containing the active ingredient (AI) isopropyl alcohol. This new temporary amendment permits all the registration modifications outlined in the March and April modifications, while also expanding the criteria for the types of products that qualify for the provisions of this amendment.
EPA states that this temporary, time-limited amendment to PR Notice 98-10, dated May 11, 2020, will extend some of the supply chain flexibilities to products used in the food manufacture and preparation industries. Specifically, this temporary amendment expands these flexibilities to manufacturers of food-contact surface sanitizer products containing isopropyl alcohol and adds isopropyl alcohol to the list of AIs commodity chemicals allowed to be changed by notification in order to use any similar source to produce List N registered disinfectant products.
According to EPA, these isopropyl alcohol sanitizer products are not to be applied directly to food. Instead, they are used to sanitize equipment and surfaces used in food manufacturing and food preparation.
EPA intends for these flexibilities to increase the availability of products for use against the SARS-CoV-2. This third temporary modification to PR Notice 98-10, according to EPA, is in response to feedback from the food manufacture and preparation industries that are experiencing challenges acquiring sanitizers for use in production facilities processing low-moisture products like cereal, flour, and industrial baked goods.
Additional information on submission information for registrants is available at Temporary Amendment to PR Notice 98-10 and on our blog.

On December 28, 2018, the California Department of Pesticide Regulation (DPR) issued Notice 2018-26 changing its Notice of Decision (NOD) and public report documentation for proposed registration decisions to ensure continued compliance with its certified regulatory program obligations under the California Environmental Quality Act (CEQA). The new changes to the NODs and public report documentation will be effective May 1, 2019.
These changes are as a result of a 2014 lawsuit brought by Pesticide Action Network North America (PANNA), et al. challenging DPR’s acceptance of label amendments for two previously registered dinotefuran pesticide products. The First District Court of Appeal held that DPR’s NODs and public reports supporting the dinoteferan registration actions were deficient because DPR could not demonstrate that it properly considered certain factors specified in CEQA. In essence, the court concluded that certain CEQA requirements that DPR construed as procedural in nature were actually substantive standards that DPR must meet and adequately document in its administrative record. Specifically, the court found that DPR failed to include a checklist or other documentation with meaningful analysis explaining how DPR reached its conclusion that the approval of the proposed label changes would not cause a significant adverse impact to human health, flora, fauna, water, and air.” The court also found DPR’s discussion of alternatives and cumulative impacts inadequate. Information about that case is available in our blog item California Court of Appeal Reverses Trial Court Decision Denying PANNA’s Petition Challenging Approval by DPR of Pesticides Containing Dinotefuran.
CEQA is intended to ensure projects permitted by public agencies consider the long-term protection of the environment. DPR states that CEQA “requires state and local agencies to develop an environmental impact report (EIR) for any proposed or approved project that may have a significant effect on the environment (including human health) or a negative declaration if there is substantial evidence of no significant impacts.” EIRs provide public agencies and the public “with detailed information about a proposed project’s significant effects on the environment, describe ways these effects can be minimized, and indicate alternatives to the proposed project.” CEQA and its implementing regulations set forth in Title 3, California Code of Regulations (3 Cal. Code Regs.) Sections 6254 and 6255, also require DPR to issue a weekly Notice of Proposed Decisions to Register Pesticide Products and Public Report, listing each proposed decision to register and amend pesticide products for a 30-day public comment period.
Changes to the NOD and Public Report Documentation
To address concerns raised by the court and to protect its certified program status, on January 3, 2018, DPR issued California Notice 2018-01 (“Expanding Use of Pesticide Products Under Reevaluation”), providing that, effectively immediately, DPR “will not act upon an Application for Pesticide Registration or Application to Amend Pesticide Product if DPR determines the registration or acceptance would potentially ‘expand use’ … of an active ingredient or pesticide product currently under reevaluation until the conclusion of the reevaluation.”
With Notice 2018-26, DPR will change the documentation associated with its environmental analysis in the NODs and public reports. According to Notice 2018-26, the revised NODs and public reports will address the following areas for each pesticide product noticed for registration:
- Discussion of DPR’s certified program under CEQA;
- Relevant DPR regulations for the proposed decision and public report;
- Detailed description of the project;
- Overview of the registration program, scientific evaluation process, and continuous evaluation;
- Environmental and human health factors examined (i.e., checklist containing the following CEQA areas: human health, flora, fauna, water, and air);
- Discussion of feasible alternatives and mitigation;
- Discussion of existing environmental conditions and cumulative impacts; and
- Conclusion explaining DPR’s analysis of potential significant adverse impacts to human health, flora, fauna, water, and air.
In addition, each public report will include the proposed label. For label amendments, DPR will include both the proposed label and currently accepted label.
In summary, effective May 1, 2019, DPR “will no longer post new products and label amendments exiting the formal evaluation process as proposed to register for the 30-day public comment period until DPR completes a public report explaining why the new product or label amendment is not reasonably expected to cause a significant adverse impact to human health, flora, fauna, water, and air.” New products and label amendments that exit the formal evaluation process prior to May 1, 2019, will be posted for the 30-day public comment period using the current NOD documentation.
The impact of these changes could be substantial from a timing and DPR workload perspective and, thus, of significant concern to registrants. DPR has stated it is reviewing its internal processes and procedures and hiring additional staff to accommodate changes in workload as a result of the NOD and public report documentation changes. This is based, in part, on the fact that if current evaluation reports are not available for each CEQA checklist area (i.e., human health, flora, fauna, water, and air), DPR staff may need to review prior evaluation reports, documentation in product files, U.S. Environmental Protection Agency (EPA) risk assessments, and other available information to develop the public report. Moreover, DPR states that if it does not have adequate information to address each CEQA checklist area, the product may need to reenter DPR’s formal evaluation process. All of these factors could significantly extend the amount of time DPR takes to review a new product or amendment, as it must now develop these public reports prior to proposing registration decisions with a 30-day public comment period, and that time could be even longer in cases where DPR determines it requires additional evaluation of the product and/or data necessary to complete such public reports.

On March 22, 2018, the U.S. Environmental Protection Agency (EPA) released the Pesticide Registration Notice (PR Notice) 2018-1 issued by the Office of Pesticide Programs (OPP) entitled “Determination of Minor Use under Federal Insecticide, Fungicide, and Rodenticide Act Section 2(ll)” (PR Notice 2018-1). Notice of Availability issued on March 21, 2018. 83 Fed. Reg. 12385. The PR Notice states that it “describes the revised approach to interpreting economic minor use based on the concept of the registration of a pesticide as an investment.” It “revises the method and criteria used by EPA for evaluating ‘sufficient economic incentive’ under FIFRA section 2(ll)(2),’” and it “also clarifies that minor use under FIFRA section 2(ll)(1) is based on acreage reported in the [U.S. Department of Agriculture (USDA)] Census of Agriculture.”
Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) Section 2(ll)(1) defines a minor use of a pesticide as a use on a crop grown on 300,000 acres or less in the United States. Section 2(ll)(2) of FIFRA defines a minor use of a pesticide as one that lacks sufficient economic incentive to seek or maintain a registration but has private or social value.
PR Notice 2018-1:
- Clarifies that the USDA’s most recent Census of Agriculture, conducted every five years by the USDA’s National Agricultural Statistics Service (NASS), is the appropriate source for data on acreage or crops grown in the U.S. to establish a minor use under the acreage definition in FIFRA 2(ll)(1);
- Revises and provides guidance to registrants concerning the method used by EPA for evaluating “sufficient economic incentive” under FIFRA Section 2(ll)(2); and
- Explains how qualitative information may be used to inform the quantitative analysis and interpret the results.
Previously, EPA’s interpretation of economic minor use in Section 2(ll)(2) was based on PR Notice 97-2. EPA states PR Notice 2018-1 supersedes PR Notice 97-2. EPA states that through PR Notice 2018-1, EPA “seeks to identify and encourage the registration of pesticides for minor uses to protect communities from harmful pests.” EPA states in PR Notice 2018-1 that “the existing methods for identifying an economic minor use in PRN 97-2 do not consider all relevant factors which could affect the incentives of a registrant to apply to register a minor use,” and that “use of the approach in PRN 97-2 to identify economic minor uses could prevent applicants from registering pesticides that would be beneficial to users and growers, thus limiting the availability of pesticides for certain use sites.” For this reason, “EPA revised the method to determine an economic minor use.”
PR Notice 2018-1 is significant because it can be applied to conventional pesticides, biopesticides, and antimicrobial pesticides to determine whether they meet the definition of minor use. The criteria in PR Notice 97-2 only applied to conventional pesticides.
EPA states the rationale for revising the PR Notice to consist of the following:
- EPA has decided to revise the policy on determining minor use.
- First, PRN 97-2 is outdated regarding the crops that would not meet the acreage definition of a minor use under FIFRA section 2(ll)(1). PRN 97-2 contained a fixed list of crops that were grown on more than 300,000 acres in 1997, but cropping patterns change over time and the list of crops provided in PRN 97-2 is no longer accurate.
- Second, the method in PRN 97-2 does not accurately reflect economic incentive to register pesticides. Gross revenue is not an appropriate measure for estimating returns on an investment; since it does not account for production and distribution costs, it overstates the returns to the investment. However, revenue from a single year understates the time period when a firm would receive a return on an investment. Finally, gross revenue at full market potential does not account for the difference in timing between costs of registration and future returns. Costs are likely to be incurred at the beginning of registration, whereas revenues will occur over multiple, future years.
- Third, PRN 97-2 applies only to registration actions on conventional pesticides. The notice specifically states that it does not apply to registrations of biopesticides and antimicrobials (e.g., disinfectants). The method described in this PRN may be used to evaluate the registration incentive for all types of products registered by each of OPP's registering divisions.
Additionally of note, EPA states in PR Notice 2018-1 that seeking minor use designation is not required as part of the pesticide registration process. It is an optional designation that an applicant can seek to obtain certain incentives associated with minor uses, such as:
- Extension of exclusive use of data under FIFRA Section 3(c)(1)(F)(ii); and
- Qualifying for an exemption from the fee or waiver of a portion of the registration service fee for an application for minor uses of a pesticide under FIFRA Section 33(b)(7)(D).

The U.S. Environmental Protection Agency (EPA) recently announced, in two separate notices, that it is initiating a process to revise (1) certain requirements in the Agricultural Worker Protection Standard (WPS) (82 Fed. Reg. 60576 (Dec. 21. 2017)); and (2) to revise the minimum age requirements in the Certification of Pesticide Applicators (C&T) rule. 82 Fed. Reg. 60195 (Dec. 19. 2017).
For the WPS rulemaking, the provisions at issue were identified as part of the public comments received in response to Executive Order (EO) 13777, Enforcing the Regulatory Reform Agenda. Three provisions in particular were the subject of public comment, and later consideration by the EPA’s Office of Pesticide Programs (OPP) Pesticide Program Dialogue Committee (PPDC) at its November 2, 2017, meeting. The three provisions are: minimum age (the 2015 WPS specifies a minimum age of 18 years, with an exemption for owners of agricultural establishments and their immediate family members); designated representative (the 2015 WPS requires employers to provide pesticide application information and safety data sheets to a designated representative of a worker or handler under specified circumstances); and application exclusion zones (AEZ) (the 2015 WPS requires the establishment of AEZs with respect to outdoor production on farms, nurseries, and forests to reduce the number of incidents where workers or others are exposed to pesticides during agricultural pesticide applications).
EPA also announced that the compliance dates in the revised WPS remain in effect and that EPA has no intent to extend them. This means that most provisions in the revised WPS went into effect on January 2, 2017, and compliance with two additional requirements will begin on January 2, 2018. The two requirements include compliance with the display of pesticide safety information, and pesticide handlers must temporarily suspend applications if workers or others enter in the application zone during pesticide applications. The only requirements in the revised WPS that will not be in effect as of January 2, 2018, are the requirements that the worker and handler pesticide safety training material cover the expanded content at 40 C.F.R. §§ 170.401(c)(3) and 170.501(c)(3). The 2015 revised WPS provided that compliance with the expanded pesticide safety content in these sections was not required until 180 days after EPA publishes in the Federal Register a notice of availability of certain training materials. While there are training materials available that meet the expanded content requirement, EPA has not yet published such a Federal Register and apparently does not intend to do so until after the rulemaking announced on December 21 has concluded.
For the C&T rule, EPA expects to “publish a Notice of Proposed Rulemaking to solicit public input on proposed revisions to the rule by the end of FY2018,” and it has no plans to change the implementation dates in the January 4, 2017, final rule. The C&T notice states that “EPA has determined that further consideration of the rule’s minimum age requirements is warranted through the rulemaking process” after it considered comments received pursuant to EO 13777, revisiting the record, and reviewing the applicable statutory.

On October 5, 2017, the U.S. Environmental Protection Agency (EPA) issued a notice of extension of the comment period for the draft guidance Pesticide Registration Notice (PR Notice) 2017-XX: Notifications, Non-notifications and Minor Formulation Amendment issued on September 6, 2017. Comments now must be received by EPA on or before December 5, 2017. The notice states that it will “allow stakeholders additional time to submit comments on the proposed guidance.” Eleven comments were filed in the docket, most of which expressed significant concern with changes EPA is proposing, in addition to requesting an extension to the previous deadline which was set to end on October 6, 2017.
EPA states that PR Notice 2017-XX will update and clarify “the scope of changes accepted by notification, non-notification and minor formulation amendments for all pesticide products, and supersedes both PR Notices 95-2 and 98-10 in their entirety.” A full summary of the changes in the draft guidance is available in our blog item "EPA Releases Draft Guidance for Pesticide Registrants on Notifications, Non-notifications, and Minor Formulation Amendments."
Some of the more substantive comments noted the following issues:
- Several commenters stated objections to the provisions in the draft PR Notice that would eliminate the ability of registrants of formulated products to use notification to add or change sources of either registered technical active ingredients or inert ingredients. Concerns expressed with this proposed change included the effect it would have on the ability of registrants to respond quickly to market changes and conditions, including the availability and price of technical and inert ingredients needed for formulations.
- One commenter had concerns with regard to the proposed changes to the inert ingredient disclosure statement, as EPA is “considering whether the notification method or the non-notification method is an appropriate avenue for industry requested inert disclosure based upon third-party vendor requirements.” The commenter stated that it “believes there is an approach that satisfies third-party vendors while minimizing the burden on the Agency’s resources,” and “a significant delay to this issue could have third-party vendor impacts.”
- Commenters also expressed disappointment with EPA’s notification delivery, stating that EPA “provided very little notice to Stakeholders of this major change in its policies regarding notification” and “as a result, many potentially affected registrants may overlook this change and fail to file comments on it.”

On September 22, 2017, the U.S. Environmental Protection Agency (EPA) issued a notice in the Federal Register (82 Fed. Reg. 44406) announcing the availability of two final Pesticide Registration Notices (PRN):
- PRN 2017-1: Guidance for Pesticide Registrants on Pesticide Resistance Management Labeling, which updates PRN 2001-5 and provides guidance for registrants to follow when developing resistance management information to include on their pesticide labels. It addresses “end-use herbicide, fungicide/bactericide, or insecticide/acaricide products that are intended mainly for agricultural and certain non-crop land areas under commercial or government-sponsored pest management,” and applies in particular to “all field use agricultural pesticide products, as well as pesticides which are labeled for greenhouse production, sod farms, ornamental crops, aquatic vegetation, rights-of way, and pest management along roadways.”
- PRN 2017-2: Guidance for Herbicide Resistance Management Labeling, Education, Training, and Stewardship, which “communicates the agency's approach to address herbicide-resistant weeds.” It is “germane to end-use herbicide products used in agriculture, including commercial turf and sod farms, ornamental production in the open.” It also applies to “non-agricultural use sites such as golf courses, aquatic vegetation, rights-of-way and vegetation management along roadways.”
These final PRNs reflect consideration of public comments submitted on the draft PRNs. Also available in the dockets are EPA’s responses to comments on the draft PRNs: Response to Comments on PRN 2017-1; and Response to Comments on PRN 2017-2. EPA states that “PRNs are issued by the Office of Pesticide Programs (OPP) to inform pesticide registrants and other interested persons about important policies, procedures, and registration-related decisions, and to provide guidance to pesticide registrants and OPP personnel.”
More information on PRNs is available on our blog under key phrase pesticide registration notice.

On September 6, 2017, the U.S. Environmental Protection Agency (EPA) published a notice in the Federal Register announcing the availability of and seeking public comment on draft guidance, Pesticide Registration Notice (PR Notice) 2017-XX: Notifications, Non-notifications and Minor Formulation Amendments. EPA states it is issuing this notice to “align the notification program with the requirements of the Food Quality Protection Act (FQPA) and [the Pesticide Registration Improvement Act (PRIA)] and to clarify the processes for accepting minor, low risk registration amendments to be accomplished through notification, non-notification or as accelerated amendments.” EPA is requesting comments, and specifically information on projected cost implications of this draft updated guidance.
PR Notices are issued by the Office of Pesticide Programs (OPP). EPA states that PR Notice 2017-XX will update and clarify “the scope of changes accepted by notification, non-notification and minor formulation amendments for all pesticide products, and supersedes both PR Notices 95-2 and 98-10 in their entirety.” The PR Notice lists the changes from PRN 98-10 in a table. Those changes include:
In addition to the changes listed on the table, modifications to PR Notice 98-10 consist of the following:
- F. Product Composition: (1) Pesticide Category -- Under PR Notice 98-10, the pesticide categories "disinfectant" and "sanitizer" were two pesticide categories that were allowed to be added to a label by notification. Under the proposed PR Notice, "disinfectant" and "sanitizer" were removed.
- F. Product Composition: (2) Odor -- Under PR Notice 98-10, the terms "fragrance free" and "unscented" were allowed to be added to a label by a notification provided that the product is odorless or nearly odorless and contains odor-masking ingredient such as a perfume. Under the proposed PR Notice, these terms were removed.
Minor Formulation Amendments
- A. Minor Formulation Amendments: (1) Addition, deletion or substitution of one or more colorants in a formulation -- Under PR Notice 98-10, if a product was intended for a use as a seed treatment or rodenticide, it would not be eligible for an accelerated review; that restriction was deleted from the proposed PR Notice.
- A. Minor Formulation Amendments: (2) Addition, deletion or substitution of one or more inert ingredients (other than colorants and fragrances) in a formulation -- Under the proposed PR Notice, if a product is a dog/cat pet spot-on product or if an inert is a bittering agent or a safener, the product would not be eligible for an accelerated review.
- A. Minor Formulation Amendments: (3) Addition, deletion or substitution of one or more fragrances in a formulation -- Under the proposed PR Notice, fragrances will be eligible for an accelerated review if all fragrance component ingredients are included on the Fragrance Ingredient List; individual fragrance component ingredients that exceed 0.1 percent (by weight) of the total pesticide product composition have existing approval for non-food use as an inert ingredient; and new/modified fragrances for antimicrobial products making public health claims are within the certified limits established for fragrances already approved for the product.
- Under the proposed PR Notice, products that are not eligible for accelerated review under minor formulation amendments are:
- Pet spot-on products;
- Change to an active ingredient source;
- Change to nominal concentration of the active ingredient; or
- Addition of new or additional Confidential Statements of Formula (CSF).
EPA Procedures to Review Notifications
Under the proposed PR Notice, EPA outlines changes to the policy for processing notifications by the Registration Division (RD) and the Biopesticides and Pollution Prevention Division (BPPD), but procedures to process notifications by the Antimicrobials Division remain the same.
One item to note under the proposed notification process for RD and BPPD is that a registrant may distribute or sell a product modified by notification once EPA receives the notification but, if EPA determines that a product has been modified through notification inappropriately, EPA may initiate regulatory and/or enforcement action without first providing the registrant with an opportunity to submit an application to amend the registration.
Registrants Submitting Minor Formulation Amendments
Under the proposed PR Notice, EPA requires that registrants submit with their application for registration a cover letter listing names and dates of all EPA accepted CSFs. EPA will consider any CSFs not listed in the cover letter as superseded/no longer valid.
Comments on this PR notice are due October 6, 2017, and can be submitted online under Docket ID EPA-HQ-OPP-2016-0671.
Registrants should review the draft PR Notice carefully, as it includes important changes. For example, the consequence for submitting a minor formulation amendment and neglecting to include a list of all current CSFs is severe. As another example, EPA signals in its proposal that proceeding to market with a product revised through the notification process may be risky if the submitter has erred in its judgment regarding what is eligible for a notification. Should the PR Notice be issued without change to this provision, submitters may wish to give close consideration to waiting until it has EPA’s written confirmation that a notification has been accepted before introducing the revised product to market. Comments on issues of concern should be considered.
