On April 12, 2018, House Agriculture Committee Chairman Michael Conaway (R-Texas) released the Committee’s draft Farm Bill reauthorization, the “Agriculture and Nutrition Act of 2018” (H.R. 2). The House Agriculture Committee passed the Farm Bill package on April 18, 2018, setting it up for a floor vote in the House. The 600-plus page draft legislation includes a number of provisions that will be of interest to pesticide registrants and the pesticide user community, including the following sections:
- Section 9119. Enactment of Pesticide Registration Improvement Act of 2017: This provision would enact the Pesticide Registration Improvement Extension Act (known as PRIA-4), which authorizes the U.S. Environmental Protection Agency (EPA) to continue to collect $40 million in registration and maintenance fees critical to supporting the pesticide registration process.
- Section 8303. Consultation under the Endangered Species Act (ESA): Subsection (a) would eliminate ESA Section 7 consultation requirements for U.S. Forest Service projects where a “not likely to adversely affect” determination has been made. Subsection (b) requires ESA Section 7 consultation for forest management activities carried out under the Farm Bill to be completed within a 90-day period.
- Sections 9117 and 9118. Clean Water Act (CWA) Pesticide Permitting: Together these two provisions amend the CWA and the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) to eliminate CWA National Pollutant Discharge Elimination System (NPDES) permitting for FIFRA-compliant pesticide applications. These sections incorporate the regulatory relief language from previously proposed stand-alone bills aimed at eliminating the dual regulation of pesticide applications into, over, and near surface waters, which passed the House in the 115th Congress (H.R. 953) and has been proposed in the Senate (S.340).
The full text of H.R. 2 and a section-by-section summary are available on the House Agriculture Committee Farm Bill webpage along with several related fact sheets. The Agriculture Committee expects to mark-up the bill this week.

On April 10, 2018, the U.S. Environmental Protection Agency (EPA) announced the availability of a draft Science Policy document intended to reduce the use of animals in testing chemicals to evaluate whether they cause an allergic reaction, inflammation, or sensitization of the skin. According to EPA, the document, Draft Interim Science Policy: Use of Alternative Approaches for Skin Sensitization as a Replacement for Laboratory Animal Testing, “describes the science behind the non-animal alternatives that can now be used (in vitro, in silico, in chemico) to identify skin sensitization.” The draft Science Policy states that the Office of Pesticide Programs (OPP) and Office of Pollution Prevention and Toxics (OPPT) will immediately begin to accept submissions of new approach methodologies (NAM) and defined approaches (DA) as described in the draft Science Policy. EPA notes that there are multiple domestic and international activities ongoing that will allow for refinement and expansion of this draft Science Policy to other DAs and additional NAMs and support global harmonization of DAs for skin sensitization. According to the draft Science Policy, OPP and OPPT “will continue to be active participants in these activities to ensure regulatory acceptance and will continue to support cross-sector collaborations that enhance animal welfare, and accelerate the implementation of NAMs.” Comments on the draft Science Policy document must be submitted to Docket Number EPA-HQ-OPP-2016-0093 by June 9, 2018.
The draft Science Policy is the result of national and international collaboration between the Interagency Coordinating Committee on the Validation of Alternative Methods, the National Toxicology Program’s Interagency Center for the Evaluation of Alternative Toxicological Methods, the European Union Reference Laboratory for Alternatives to Animal Testing, and Health Canada’s Pest Management Regulatory Agency.

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).

On February 22, 2018, the Superior Court of the State of California, County of Sacramento, issued a judgment granting petition for writ of mandate and declaratory and injunctive relief (Judgment) to suspend further chemical activities undertaken by the California Department of Food and Agriculture (CDFA) to control or eradicate pests under the Statewide Plant Pest Prevention and Management Program (the Project) until CDFA has certified a Program Environmental Impact Report (PEIR) that corrects violations of the California Environmental Quality Act (CEQA) identified in the court’s ruling.
CDFA is charged with promoting and protecting the state’s agricultural industry, and preventing the introduction and spread of injurious insect or animal pests, plant diseases, and noxious weeds. Cal. Food & Agr. Code §§ 4011 401.51 403. CDFA developed the Project to control targeted pests or pathogens, and includes activities such as pest rating (evaluation of a pest’s environmental, agricultural, and biological significance); identification, detection, and delimitation of new pest populations; pest management response (which may include eradication and/or control of new or existing pest populations); and prevention of the movement of pests into and within California.
The present case was brought after CDFA sought to comply with CEQA by preparing a single PEIR that provides a consolidated set of management practices rather than prepare Environmental Impact Reports (EIR) specific to particular pest management activities. Petitioners alleged that CDFA violated CEQA by certifying the PEIR for the Project and in related proceedings that CDFA violated CEQA by subsequently expanding the Statewide Plant Pest Prevention and Management Program to allow increased use of certain pesticides (Merit 2F and Acelepyrn) for the treatment of Japanese beetles without adequate environmental review.
The numerous CEQA violations identified by the court are set forth in a Consolidated Ruling on Submitted Matters (Consolidated Ruling) issued January 8, 2018, and attached as Exhibit 1 to the Judgment. The Consolidated Ruling discusses the following topics:
- Does the PEIR’s tiering strategy violate CEQA?
- Does CEQA require the Department to issue a Notice of Determination (NOD) anytime is carries out or approves a site-specific activity?
- Does the PEIR contain an adequate project description?
- Does the PEIR contain an adequate description of the baseline environmental setting?
- Does the PEIR fail to adequately analyze environmental impacts?
- Does the PEIR fail to adequately analyze the Project’s cumulative impacts?
- Does the PEIR improperly defer mitigation measures or conceal them as Program Features?
- Does the PEIR fail to adequately consider a range of reasonable alternatives to the Project?
- Did the Department violate CEQA’s notice and consultation requirements?
- Did the Department adequately respond to public comments on the DRAFT PEIR?
- Did the Department properly use addenda to modify the PEIR?
The court found multiple, broad-based issues with the PEIR, including, for example, a decision that the PEIR violates CEQA “because it adopts an unlawful tiering strategy, granting the Department authority to implement a broad range of practices without evaluating the site-specific conditions to determine whether the environmental impacts were covered in the PEIR.” The Consolidated Ruling also discusses particular failures of the PEIR. Additionally, of potential interest is the court’s opinion with regard to whether the PEIR failed to disclose and analyze impacts on sensitive biological resources, which Petitioners argued was based on several grounds: (i) an assumption that spraying “generally” will not occur near sensitive resources and fails to analyze potential impacts from pesticide drift; (ii) a conclusion, without substantial evidence, that the Project will have less-than-significant impacts on sensitive species; (iii) a conclusion, without substantial evidence, that traps and lures will not have significant impacts on non-target species; (iv) the use of improper thresholds of significance for impacts to pollinators and organic farming; and (v) a failure to define, disclose, and analyze impacts on wetlands.
The court did not find issues with the PEIR as it related to CDFA’s spraying assumptions and CDFA’s determinations of potential impacts on sensitive species, pesticide drift, or organic farming. The court likewise rejected Petitioner’s other challenges to the PEIR’s analysis of biological impacts, including the PEIR's analysis of traps/lures and of the species evaluated in the Ecological Risk Assessment (ERA).
The court did, however, agree with Petitioners that the PEIR improperly ignored potentially significant impacts to pollinators. The court stated that the PEIR considered impacts to pollinators significant only if (1) the pollinator species impacted were “special status,” or (2) the impacts would result in a secondary change in the physical environment (such as conversion of land from agricultural to non-agricultural use). The PEIR did not consider whether the Project might adversely impact non-special-status pollinators, despite acknowledging that “healthy pollinator populations are critical to protecting the environmental quality and agricultural resources of the state,” and that “Colony Collapse Disorder” and “pollinator decline” are “ongoing ... serious” problems. The court found that CDFA’s “‘voluntary’ actions to benefit pollinator species are not, by themselves, sufficient to justify the lack of analysis and enforceable mitigation measures for the potentially significant impacts to non-special-status pollinators.”
The immediate effect of this decision is the inability for CDFA to continue “chemical activities … to control or eradicate pests under the [Statewide Plant Pest Prevention and Management] Program except as authorized under CEQA independent of the PEIR.” Should this decision stand, registrants and stakeholders should be interested in whether and how CDFA modifies the PEIR to support its pest control and management activities.

On March 8, 2018, the U.S. Environmental Protection Agency (EPA) announced its release of final guidance clarifying where first aid statements should appear on the label of pesticide products. EPA also posted a response to public comments. Links to the final guidance and to the response to public comments documents are below:
EPA states that it was prompted to develop this guidance when it learned “that there was a discrepancy in how the ‘location of first aid statement,’ per [40 C.F.R. Section 156.68(d)] is interpreted by EPA and those in the pesticide registrant community.” EPA notes that its review and approval of pesticide labeling is generally of a “master” label and thus does not always include a review of the location or placement of specific language on a label.
On December 7, 2016, EPA posted a memorandum for public comment entitled “EPA’s Guidance for Pesticide Registrants on Location of the First Aid Statement and Clarification on Definition of Label ‘Panel’ per 40 CFR 156.68” to clarify the interpretation of the term “panel” in the context of 40 C.F.R. 156.68 and to clarify where first aid statements must appear on pesticide labels, based on their Toxicity Category.
In its final guidance, EPA states it “will continue to require that Toxicity Category I products have the first aid statements on the front panel except in cases where a variation has been approved.” Further, based on comments received and the wide reliance by the regulated community on the interpretation that “any panel” includes inside panels, EPA is changing its position from its 2016 memorandum and now “will not require Toxicity Category II and III products to bear the first aid statements on a visible front, back or side panel.”
EPA also listed three recommendations for registrants to consider when printing their container labels:
- For Toxicity Category I products, EPA strongly recommends that registrants consider placing duplicative first aid language on the very back page of the booklet/accordion/saddle stitch label that is immediately “stuck” to the container in case the booklet/accordion/saddle stitch label is accidentally removed.
- Regardless of whether a registrant chooses to place the first aid statements for Toxicity Categories II and III products on a visible front, back, side or inside panel, EPA recommends that duplicative first aid language appear on the very back page of the booklet/accordion/saddle stitch label that is immediately attached to the container in case the booklet/accordion/saddle stitch label is accidentally removed. EPA states that this recommendation is not intended to suggest other information that registrants typically include on the very back page should be moved elsewhere.
- EPA recommends that the registrant community consider designing new booklets/accordion/saddle stitch labels that are not easily removed from the containers. Per 40 C.F.R. Part 156.10(a)(4), the labels are to be “securely attached” to the immediate container of the pesticide product. EPA believes that in many instances these labels are easily removed which is why, EPA states, it believes many registrants have already chosen to put the duplicative first aid statements on the very last page of the label that is attached to the container.
Registrants should review this guidance carefully, as this issue has been the subject of concern and controversy for a number of registrants.

On March 6, 2018, the U.S. Environmental Protection Agency (EPA) issued a proposed rule (pre-publication version available here) to add hazardous waste aerosol cans to the category of universal wastes regulated under the federal Resource Conservation and Recovery Act (RCRA) regulations (Title 40 of the C.F.R., Part 273), entitled Increasing Recycling: Adding Aerosol Cans to the Universal Waste Regulations. EPA cites as authority for this change Sections 2002(a), 3001, 3002, 3004, and 3006 of the Solid Waste Disposal Act, as amended by RCRA, as amended by the Hazardous and Solid Waste Amendments Act (HSWA). EPA states the streamlined Universal Waste regulations are expected to:
- Ease regulatory burdens on retail stores and other establishments that discard aerosol cans by providing a clean, protective system for managing discarded aerosol cans;
- Promote the collection and recycling of aerosol cans;
- Encourage the development of municipal and commercial programs to reduce the quantity of these wastes going to municipal solid waste landfills or combustors; and
- Result in an annual cost savings of $3.0 million to $63.3 million.
As aerosol cans are “widely used for dispensing a broad range of products” including pesticides, the proposed rule may have implications for chemical companies that create and distribute pesticide products marketed in aerosol cans. Hazardous waste aerosol cans that contain pesticides are also subject to Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) requirements, including compliance with the instructions on the product label. Under 40 C.F.R. Section 156.78, a flammability label statement is required for pressurized pesticide product products that states “Do not puncture or incinerate container,” but EPA’s 2004 determination (that will be posted to Docket No. EPA-HQ-OLEM-2017-0463 on www.regulations.gov for this proposed rule) allows for the puncturing of cans. The proposed rule states:
- EPA issued a determination that puncturing aerosol pesticide containers is consistent with the purposes of FIFRA and is therefore lawful pursuant to FIFRA section 2(ee)(6) provided that the following conditions are met:
- The puncturing of the container is performed by a person who, as a general part of his or her profession, performs recycling and/or disposal activities;
- The puncturing is conducted using a device specifically designed to safely puncture aerosol cans and effectively contain the residual contents and any emissions thereof; and
- The puncturing, waste collection, and disposal, are conducted in compliance with all applicable federal, state and local waste (solid and hazardous waste) and occupational safety and health laws and regulations.
- EPA anticipates that this 2004 FIFRA determination would not be affected by the proposed addition of hazardous waste aerosol cans to the universal waste rules.
Comments will be due 60 days after the proposed rule’s publication in the Federal Register.

On February 28, 2018, the U.S. Environmental Protection Agency (EPA) announced the availability of three Group B -- Antimicrobial Efficacy Test Guidelines, under Series 810, Product Performance Test Guidelines. The guidelines provide recommendations for the design and execution of laboratory studies to evaluate the effectiveness of antimicrobial pesticides against public health microbial pests. 83 Fed. Reg. 8666. The three final guidelines are:
EPA states these “test guidelines are part of a series of test guidelines established by the Office of Chemical Safety and Pollution Prevention (OCSPP) for use in testing pesticides and chemical substances. The test guidelines serve as a compendium of accepted scientific methodologies and protocols for testing that is intended to provide data to inform regulatory decisions.”
EPA issued draft guidelines in June 2015 and solicited comments. EPA states that some comments received on those draft guidelines have been incorporated into the final versions. EPA states that the revision “is more user friendly and clarifies topics such as confirmatory data, repeat testing, hard water formulation, wetness determination testing for towelettes, and internal toilet testing … [and] also includes information on supplemental testing policies such as lower certified limits, revision of the AOAC Use Dilution Method performance standards and clarified technical details for efficacy testing.”
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 No. EPA-HQ-OPP-2015-0276. More information on test guidelines is available on our blog.

On February 26, 2018, the U.S. District Court for the Eastern District Court of California issued a memorandum and order on the plaintiff’s motion for preliminary injunction (Order) to “enjoin the listing of glyphosate under Proposition 65 (Prop 65) and the application of its attendant warning requirement pending a final judgment in this case and set a schedule for expedited final resolution of the case.” The Order (1) grants plaintiffs’ request for a preliminary injunction enjoining the warning requirement of California Health & Safety Code § 25249.6 as to glyphosate; and (2) denies the request for a preliminary injunction enjoining defendants from listing glyphosate as a chemical known to the State of California to cause cancer under California Health & Safety Code § 25249.8. Specifically, the Order states: “pending final resolution of this action, defendants … are hereby ENJOINED from enforcing as against plaintiffs … California Health & Safety Code § 25249.6’s requirement that any person in the course of doing business provide a clear and reasonable warning before exposing any individual to glyphosate.” Although this is only a preliminary injunction while the case continues further resolution, it is extremely significant that, for now, glyphosate will continue to be listed on California’s Prop 65 list as a “chemical known to the State of California to cause cancer,” but products containing glyphosate will not be required to comply with the warning requirement.
Plaintiffs’ memorandum supporting its motion for preliminary injunction states that Prop 65’s requirement for products containing glyphosate to include a warning that glyphosate is “known to the State of California to cause cancer” is unconstitutional under the First Amendment, and, if allowed to go into effect, will cause Plaintiffs’ “reputational, competitive, and economic harms for which they cannot be compensated.” Plaintiffs state that the “legal merit of their First Amendment claim is indisputable and obvious on the face of the attached documents without any need for discovery, and thus the claim is appropriate for expedited judicial resolution.” California’s Office of Environmental Health Hazard Assessment (OEHHA), the agency responsible for implementing Prop 65, listed glyphosate as a chemical known to the state of California to cause cancer on July 7, 2017, and the attendant warning requirement would have taken effect on July 7, 2018.
In support of denying the request for a preliminary injunction enjoining defendants from listing glyphosate under Prop 65, the court states that plaintiffs “have not shown a likelihood of success on the merits of their claim that the listing of glyphosate violates the First Amendment, because the listing is government speech, not private speech … [and it] is only the upcoming July 2018 deadline for providing the [Prop 65] warning that compels private speech.” The court noted further that Plaintiffs “have not shown a likelihood of irreparable harm should the court fail to enjoin the listing of glyphosate, because any harm that plaintiffs might suffer is caused by the warning requirements of [Prop 65], rather than the listing itself.” Accordingly, the court denied a preliminary injunction based on plaintiffs’ claim that the glyphosate listing violates the First Amendment.
On the other hand, in support of granting the request for a preliminary injunction enjoining the application of the attendant warning requirement, the court stated:
- On the evidence before the court, the required warning for glyphosate does not appear to be factually accurate and uncontroversial because it conveys the message that glyphosate’s carcinogenicity is an undisputed fact, when almost all other regulators have concluded that there is insufficient evidence that glyphosate causes cancer.
The court also stated that the required warnings are “false and misleading” and that plaintiffs “have shown that they are likely to succeed on the merits of their First Amendment claim, are likely to suffer irreparable harm absent an injunction, and that the balance of equities and public interest favor an injunction, the court will grant plaintiffs’ request to enjoin [Prop 65]’s warning requirement for glyphosate.”
This case, while not the end of the story, is a very significant development both for glyphosate specifically and perhaps for Prop 65 warning requirements generally. Industry should follow this case closely given the implications for glyphosate and potentially other Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA)-regulated pesticides and chemicals generally. Some in industry have long been concerned that Prop 65 warning requirements contradict conclusions supported by the data and reached by other agencies such as the U.S. Environmental Protection Agency (EPA). This decision is a huge preliminary win for those with these concerns and, depending on the ultimate outcome of the case, could provide a precedent for additional challenges related to other substances. The potential reach of the case beyond glyphosate, however, will likely be dictated heavily by the facts of each case.

On February 15, 2018, the U.S. Environmental Protection Agency (EPA) added resources to its website regarding the Worker Protection Standard (WPS) and the Application Exclusion Zone (AEZ) requirements of the WPS. As of January 2, 2018, full compliance is required with all of the AEZ-related requirements in the WPS. The new EPA website resources include:
While many welcome EPA’s guidance on the many thorny issues presented by the WPS and AEZ requirements, some believe that in places, the newly issued guidance raises additional questions and leaves some significant questions unaddressed. Given the controversy over this rule, this new guidance should be reviewed closely.
More information on the WPS, including EPA’s December 2017 announcement of its intention to revise the AEZ and other WPS provisions, and current implementation deadlines can be found on our blog under key word WPS and key phrase Worker Protection Standard.
