On July 20, 2016, the U.S. Environmental Protection Agency (EPA) issued a memorandum attaching minutes from the April 19-21, 2016, FIFRA Scientific Advisory Panel (SAP) meeting, Transmittal of Meeting Minutes of the April 19-21, 2016 Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) Scientific Advisory Panel (SAP or Panel) Meeting Held to Consider and Review Scientific Issues Associated with “Chlorpyrifos: Analysis of Biomonitoring Data.” This SAP was convened to advise EPA regarding the evaluation of biomonitoring chlorpyrifos data from epidemiology studies conducted by the Columbia Center for Children’s Environmental Health (CCCEH).
The minutes indicate that the SAP has significant concerns with EPA’s proposal to use the biomonitoring chlorpyrifos data from the CCCEH epidemiology studies to establish a point of departure (PoD) for chlorpyrifos risk assessment. The minutes state: “Because many uncertainties cannot be clarified, the majority of the Panel does not have confidence that the Columbia Center for Children’s Environmental Health (CCCEH) cord blood data on chlorpyrifos concentrations can accurately be used in quantitative risk assessment to determine a Point of Departure (PoD).” A major source of uncertainty cited by the FIFRA SAP is “the lack of verification and replication of the analytical chemistry results that reported very low levels of chlorpyrifos (pg/g),” because EPA had to impute a finite quantitative value to “a large fraction of cord blood samples included in the analyses presented with levels below [level of detection (LOD)].” Moreover, some SAP members “thought the quality of the CCCEH data is hard to assess when raw analytical data have not been made available, and the study has not been reproduced.”
The SAP also, however, stated that “both epidemiology and toxicology studies suggest there is evidence for adverse health outcomes associated with chlorpyrifos exposures below levels that result in 10% red blood cell (RBC) acetylcholinesterase (AChE) inhibition (i.e., toxicity at lower doses).” Nevertheless, it agreed with EPA that “applying additional safety factors to the AChE PoDs to account for a possible noncholinergic mode of action (MOA) would be problematic because of challenges in justifying any particular value for such an adjustment.”
Of note, the SAP concluded that it would be appropriate to use a “10X intra-species extrapolation factor” in any analysis based on the cord blood data. It also identified other sources of uncertainty that should be considered in such an analysis, including “the inability of single measures of chlorpyrifos concentration in blood to provide information regarding source, frequency, duration and magnitude of exposure, and how these exposures are linked to specific outcomes measured in the CCCEH study participants.” Although EPA suggested in a Status Report filed in the chlorpyrifos litigation pending in the Ninth Circuit Court of Appeals on June 29, 2016, that the FIFRA SAP might recommend a “hybrid approach” that EPA could use in lieu of a PoD based on AChE inhibition, thereby altering the prior EPA analysis for chlorpyrifos, the SAP minutes do not include a recommendation for such a hybrid methodology.
Given the concerns expressed by the SAP regarding EPA’s proposal to derive a PoD from cord blood biomonitoring data collected in the CCCEH epidemiology studies, it may be unlikely that EPA will further pursue this specific approach. It is less clear whether EPA will be inclined to propose any further adjustments to its existing risk assessment for chlorpyrifos, which utilizes a PoD based on animal AChE data, along with intra-species and inter-species uncertainty factors and an additional Food Quality Protection Act (FQPA) 10X factor. EPA’s decision to retain the special FQPA factor in its risk assessment for chlorpyrifos will remain controversial, because it is based on an assessment of the value and significance of several epidemiology studies for chlorpyrifos that many in the pesticide industry strongly dispute. The discussion in the minutes of the uncertainties resulting from the refusal of the CCCEH investigators to provide underlying raw data may provide further support for arguments by industry that EPA should not predicate risk assessments on the epidemiology studies for chlorpyrifos before obtaining and reviewing these data.

On March 28, 2016, a three-judge panel in the U.S. Court of Appeals for the Ninth Circuit, Case Nos. 15-71207, et al. (consolidated) issued an order denying the Petitioners’ March 10, 2016, motion asking the court to adjudicate their challenges to the Environmental Protection Agency’s (EPA) registration of the pesticide Enlist Duo during remand of the registration decision to EPA, as well as their alternative request that the court stay issuance of its mandate and retain jurisdiction pursuant to the original petition for review. The brief three-sentence order did not offer any explanation as to why the court denied the relief requested by the Petitioners.
The Petitioners’ March 10, 2016, motion stated that it is “appropriate to adjudicate those arguments now, because Enlist Duo remains on the market during the limited remand, causing petitioners continued harm.” In support of their motion, Petitioners argued that the purpose of the remand was to address the “narrow question” of “synergistic effects of Enlist Duo’s two main ingredients on non-target plants,” and that an ultimate decision by EPA on this narrow issue “may have no bearing on the arguments petitioners have already briefed in this Court.” Petitioners also argued that the registrant and intervenor Dow AgroSciences LLC (DowAgro) has “reneged on its promise to the Court not to sell Enlist Duo” during the remand.
EPA and DowAgro both filed responses on March 21, 2016, opposing the Petitioners’ motion. EPA’s response to the motion stated that the court’s order remanding the matter to EPA was general in scope, and “EPA may properly choose to revisit the issues raised in Petitioners’ briefs while it also considers the new information provided by Dow regarding the synergistic effects of Enlist Duo’s two active ingredients.” Thus, if the court were to consider the Petitioners’ claims during remand, “the Court would be advising EPA as to the outcome of its remand work, which is contrary to the Court’s function.” EPA also opposed the request to stay the mandate and retain jurisdiction “because Petitioners will have ample opportunity to challenge any new agency action that EPA issues after concluding its remand work.”
DowAgro’s response stated that “[t]his Court’s order did not limit the scope of the remand, so the agency is free to alter, amend, or supersede the existing registration.” DowAgro also argued that adjudicating petitioners’ claims during remand would lead to improper “piecemeal review” because “petitioners’ challenges to the original registration may be substantially altered or mooted entirely.” With respect to the Petitioners’ allegation that DowAgro “reneged” on a promise not to sell Enlist Duo during the remand, DowAgro stated that this offer was only for “the interim period while this Court was considering the remand motion, not the indefinite period the matter was on remand to the agency.”
More information regarding the court’s original remand order is available in our blog item Ninth Circuit Denies EPA Motion for Vacatur, Grants EPA Motion for Remand.
It would have been, in the view of many, surprising for the court to agree to adjudicate Petitioners’ claims concerning the registration decision for Enlist Duo during the period that decision is remanded to EPA for further action. Similarly, it is not surprising to many that the court declined to retain jurisdiction, since the remand to EPA will not operate to constrain the ability of the Petitioners to raise the same claims in the event that EPA decides to issue a new registration for Enlist Duo following remand.
It is not clear at this juncture whether EPA will be inclined to reconsider its views concerning any of the Petitioners’ claims during the remand process. Petitioners likely will, however, have another opportunity to seek review concerning their claims, assuming they participate in the administrative process during remand, and EPA does not alter its original decision in a manner that moots those claims.

On September 22, 2105, the U.S. Environmental Protection Agency (EPA) published a notice in the Federal Register listing its revised registration service fees applicable to specified pesticide applications and tolerance actions for fiscal year (FY) 2016 that are registered under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA).
The Pesticide Registration Improvement Act of 2003 (PRIA) established FIFRA Section 33, creating a registration fee-for-service system for certain types of pesticide applications, establishment of tolerances, and certain other regulatory decisions under FIFRA and the Federal Food, Drug, and Cosmetic Act (FFDCA). Section 33 also created a schedule of decision review times for applications covered by the service fee system. EPA began administering the registration service fee system for covered applications received on or after March 23, 2004.
PRIA has been reauthorized twice, most recently by the Pesticide Registration Improvement Extension Act (PRIA 3) signed on September 28, 2012. PRIA 3 revised FIFRA section 33, reauthorized the service fee system through fiscal year 2017, and established fees and review times for applications received during fiscal years 2013 through 2017. The registration fees for covered pesticide registration applications received on or after October 1, 2015, increase by five percent from the fees published for fiscal year 2015 in the Federal Register notice issued September 26, 2013, Pesticides; Revised Fee Schedule for Registration Applications. The new fees became effective on October 1, 2015.
The notice retains the format of prior PRIA tables; it identifies the registration service fees and decision times and is organized according to the three Office of Pesticide Programs (OPP) registration divisions within EPA, with the additional sections for inert ingredients and other actions added as part of PRIA 3. Thereafter, the categories within main sections of the table are further organized according to the type of application being submitted, including new active ingredients, new uses, new products, and registration amendments There are 189 categories of activities spread across the three OPP divisions: Registration Division (63 categories), Antimicrobial Division (39 categories), and Biopesticides and Pollution Prevention Division (69 categories), plus ten inert ingredient and eight miscellaneous categories. Each has its own decision review time and service fee for FY 2016-2017. The scale of the fees differs between the three registration divisions. We note that not all submissions are subject to PRIA 3; generally speaking, any submission requiring data review will be subject to PRIA 3.
The notice also provides information on how to pay fees, how to submit applications, and the addresses for applications.
More information on the registration fees is available on EPA’s webpage FY 2016/17 Fee Schedule for Registration Applications.

On August 11, 2015, the U.S. Court of Appeals for the Ninth Circuit denied a motion for a stay pending review filed on December 18, 2014, by the Natural Resources Defense Council (NRDC), as well as a subsequent stay motion filed on February 6, 2015, by the Center for Food Safety and other petitioners (Case Nos. 14-73353 and 14-73359, consolidated). Both motions requested that the court stay an October 15, 2014, decision by the U.S. Environmental Protection Agency (EPA) to register Enlist Duo herbicide (a combination of glyphosate and 2,4,-D) for use on corn and soybeans in six Midwestern states.
NRDC and CFS, et al. (Petitioners), filed these stay motions in a case consolidating petitions for review challenging EPA’s decision to register Enlist Duo. The registrant of Enlist Duo (Dow AgroSciences) has intervened in the consolidated case. The Petitioners argue that EPA failed to consider the impacts of increased glyphosate use on monarch butterflies, and did not fully assess the potential human health effects from 2,4-D. In response, both EPA and Dow AgroSciences argue that approval of Enlist Duo will not lead to increased use of glyphosate, and that EPA fully considered all of the human health effects of 2,4-D before granting the registration.
The motions for a stay filed by the Petitioners were effectively motions for preliminary injunctive relief, an extraordinary remedy requiring that those seeking such relief show that they are likely to succeed on the merits, that there is likely to be irreparable harm, that the balance of equities tips sharply in their favor, and that an injunction is in the public interest. In denying the stay motions, the court cited Winter v. NRDC, 555 U.S. 7 (2008). In the Winter case, the Supreme Court held that irreparable injury must be likely and that a mere possibility of irreparable injury will not suffice in awarding injunctive relief. Although the court did not opine further on its rationale for denying the Petitioners’ stay motions, it may be inferred that the court determined that the Petitioners had not satisfied the rigorous prerequisites for injunctive relief.
While this decision avoids an immediate disruption in the marketing of pesticides, the potential for disruption to the registration remains until the court challenge has been resolved. As Enlist is a new product designed for use with crops genetically modified to be resistant to glyphosate and 2,4,-D, any disruption now would be especially impactful to the registrant and customers of the product. Further, it could also have a chilling effect on efforts to introduce similar new or pending products if growers perceive too great a risk of uncertainty for this or similar pesticides.

On June 12, 2015, Federal District Judge Maxine Chesney issued a decision in Ellis v. Housenger (N.D. Cal.) allowing the plaintiffs to utilize expert declarations and exhibits that were not included in the certified administrative record to support their contentions that the U.S. Environmental Protection Agency (EPA) improperly failed to consult the Fish and Wildlife Service (FWS) under Section 7 of the Endangered Species Act (ESA). The plaintiffs in the Ellis case are individual beekeepers and non-governmental organizations, and two out of the six claims in their complaint allege a failure by EPA to consult under the ESA before registering or adding new registered uses for products containing two neonicotinoid pesticides, clothianidin and thiamethoxam. Judge Chesney’s order was issued in response to separate motions by EPA and by industry intervenors Bayer Crop Science, Syngenta Crop Protection, and Croplife America to preclude the plaintiffs from utilizing extra record material to support their ESA claims.
Although EPA and the intervenors argued that the Court’s review of the ESA claims should be confined to the administrative record based on the Administrative Procedure Act (APA), Judge Chesney determined that extra record material may be used to support an allegation that an administrative agency failed to consult with the FWS as required by ESA Section 7. The Judge based this holding on two cases decided in the Ninth Circuit, Washington Toxics Coalition v. EPA and Western Watersheds Project v. Kraayenbrink, which each held that extra record material may be properly considered in determining whether an agency improperly failed to consult under ESA Section 7. The Judge rejected the contention by EPA and the intervenors that these two decisions were supplanted by Karup Tribe v. U.S. Forest Service, concluding that the “arbitrary and capricious” standard of review established by the APA is utilized to review the ESA claims, but the scope of review for these claims is not constrained by the APA.
The effect of this decision will be to allow the plaintiffs to present expert opinion and evidence concerning the claimed adverse effects of the two neonicotinoid pesticides on endangered and threatened species, including but not limited to pollinator species, that was not expressly considered by EPA when it decided to register these pesticides. The plaintiffs will argue that such extra record material establishes that there was a sufficient basis to conclude that these pesticides “may affect” endangered or threatened species for EPA’s failure to consult FWS under the ESA to be arbitrary and capricious. This preliminary ruling could materially affect review of the ESA counts because there is a substantial division of expert scientific opinion concerning the alleged adverse effects of neonicotinoid pesticides, and the Court may conclude that EPA did not afford adequate weight to some of this opinion.

On Thursday, April 30, 2015, the U.S. Environmental Protection Agency (EPA) issued interim guidance that it intends to clarify its toxicology data requirements for antimicrobial pesticides used on food contact surfaces. In addition, EPA issued a letter to antimicrobial registrants that EPA states is intended “to summarize how the Agency has been implementing 158W with respect to existing registered antimicrobial pesticides, as well as new and pending antimicrobial pesticide applications.”
The interim guidance is intended to satisfy a condition of the March 2, 2015, settlement agreement between EPA and the American Chemistry Council (ACC), which followed ACC’s July 2013 initiation of a legal challenge to the antimicrobial data requirements (subpart 158W of Title 40 of the Code of Federal Regulations) in the U.S. Court of Appeals in the District of Columbia. The settlement agreement is discussed here.
In the settlement, EPA agreed to issue, within 60 days of the Agreement becoming final, an interim guidance document explaining EPA’s interpretation of the 200 parts per billion (ppb) residue level above which additional toxicology testing would be required for indirect food uses.
The interim guidance states with regard to the 200 ppb standard:
No later than September 2, 2017, the Agency will propose a correction to 40 CFR Part 158W to make the rule’s language as it pertains to the 200 ppb level established in 40 C.F.R. § 158.2230(d) consistent with the U.S. Food and Drug Administration’s use of that same level. The proposal will be to clarify that the 200 ppb level established in the rule is based on total estimated daily dietary intake, and is not based on the amount of residue present on only a single commodity. The Agency is providing this interim guidance to registrants that the referenced 200 ppb level is based on total estimated daily dietary intake rather than on the amount of residue present on only a single commodity.
EPA states that this interpretation is consistent with the U.S. Food and Drug Administration’s (FDA) policy. In general, if pesticide residues in food resulting from use on food contact surfaces are 200 ppb or less, EPA requires certain toxicology data. If residues are greater than 200 ppb, additional data may be required, depending on other conditions such as test results.
Also in the settlement, EPA agreed to propose, within four months of the Agreement becoming final, a guidance document entitled Antimicrobial Pesticide Use Site Index (USI), and provide a 30-day comment period. The USI guidance will provide descriptions of direct food uses, indirect foods uses, and nonfood uses. The letter states the following regarding its development of the USI guidance:
The Agency is developing a guidance document called the Antimicrobial Pesticide Use Site Index (USI) that will serve as a compilation of existing use sites and will identify how each use site fits within the twelve use patterns established in 158W. The guidance document will serve to assist prospective registrants with the application requirements by making it easier for them to identify which data are necessary to register their product(s).
EPA’s letter also discusses the following regarding existing and pending antimicrobial pesticide applications:
- EPA may find it necessary, “in the context of, but not limited to, the requirements in 158W,” to call in data as each active ingredient is evaluated under the Registration Review program. EPA does not intend to conduct this generic evaluation for new products or applications to amend existing products that are covered in Pesticide Registration Improvement Extension Act (PRIA3) fee category Table 9 -- Antimicrobial Division -- New Products and Amendments.
- During early implementation of the 158W requirements, EPA recognizes that not all new applications will have all the newly-required data. EPA may thus find it appropriate to issue Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) Section 3(c)(7) conditional registrations and set a deadline for the submission of the required data.
- Any application submitted after July 8, 2013 (the effective date of the 158W requirements) must contain the required data or an adequate justification for any data requirements not submitted. On the issue of timing, applicants should explain why any data are not yet submitted and when the data can be submitted. Failure to submit required data or provide an adequate justification will result in EPA rejecting the application as incomplete under the 45/90 day preliminary technical screen under the Pesticide Registration Improvement Act (PRIA).
The settlement agreement and additional documents are available at http://www2.epa.gov/pesticide-registration/epa-data-requirements-registration-antimicrobial-pesticides-part-158w#interim and www.regulations.gov in docket EPA-HQ-OPP-2008-0110.

The U.S. Environmental Protection Agency (EPA) issued an updated schedule for the Pesticide Registration Review program that sets forth a timetable for opening dockets for the next three years, through end of fiscal year 2017 (September 2017).
Through the Pesticide Registration Review program, EPA reviews all registered pesticides at least every 15 years, as mandated by the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). Following the newly issued schedule, all pesticides registered as of October 1, 2007, will have entered the registration review process with the exception of certain biopesticides. All pesticides registered by October 1, 2007, are scheduled to be assessed by October 1, 2022.
The rodenticide and triazole groups of chemicals have had their schedules adjusted so that all chemicals in the groups will be assessed during the same time frame. The rodenticides have dockets opening in first and second quarter 2016, while the triazoles have dockets opening from fourth quarter 2015 through third quarter 2016. In addition, EPA states that it has moved some chemicals that it believes may have significant data needs earlier in the schedule, but does not specify which were moved. Those with significant moves forward in the schedule (all moved from fourth quarter 2015 to first quarter 2015) include yellow mustard seed, sulfonic acids, fluazifop butyl, isomers, and flonicamid.
More information about the Pesticide Registration Review schedule is available here.

The European Commission (EC) Standing Committee on Plants, Animals, Food and Feed has issued a guidance document entitled Draft Guidance Document on the Interpretation of the Transitional Measures for the Data Requirements for Chemical Active Substances and Plant Protection Products according to Regulation (EU) No. 283/2013 and Regulation (EU) No. 284/2013. Following the adoption in 2009 of Regulation (EC) No. 1107/2009 concerning the placing of plant protection products (PPP), additional regulations were adopted to establish the necessary data requirements for active substances and PPPs. In 2013, Regulation (EU) No. 283/2013 (amended by Regulation (EU) No. 1136/2014) updated the data requirements for active substances, while Regulation (EU) No. 284/2013 updated data requirements for products. These Regulations include transitional measures to explain when certain applications can rely upon former data requirements and when the updated data requirements must be satisfied.
The Guidance provides two charts describing the transitional measures for: (1) applications for approval, renewal, or approval or amendment of approval of Active Substances; and (2) applications for authorization, renewal of authorization, or amendment of authorization of Plant Protection Products. Each chart describes the type of application at issue and the resulting data requirements. For authorization applications, the Guidance divides the types of applications and resulting data requirements into four active substances categories: (1) AIR-2 active substances; (2) AIR-3 active substances/substances not yet renewed; (3) new active substances; and (4) mixtures.
The Guidance was developed to assist EU Member States in consistently applying and interpreting these transitional measures. Many of the data requirement decisions depend on the type of active substances and whether an application is submitted before or after December 31, 2015, so companies considering or planning to submit applications should review the Guidance carefully to determine what data requirements may be applicable.

On January 20, 2015, the National Marine Fisheries Service (NMFS) issued its latest Biological Opinion (BiOp) in a series of BiOps evaluating potential effects of pesticide use on salmon in the Pacific Northwest. When the U.S. Environmental Protection Agency (EPA) decides to permit continued registration of a pesticide (during reregistration or registration review), Endangered Species Act (ESA) Section 7(a)(2) requires EPA to determine, in consultation with the NMFS and/or the Fish and Wildlife Service (FWS), that continued registration is not likely to jeopardize the continued existence of any endangered or threatened species. Under current procedures, EPA scientists make an initial threshold determination whether or not continued registration “might” have such an effect, followed by referral to the FWS or the NMFS for formal consultation in those instances where that threshold is met.
The January 20, 2015, NMFS BiOp concerns the pesticides diflubenzuron, fenbutatin oxide, and propargite, and is one in a series of NMFS BiOps for Pacific salmon. As part of litigation that began in 2001, the Ninth Circuit Court of Appeals ordered EPA to determine whether it should have consulted with NMFS concerning reregistration of 55 specific pesticides. EPA subsequently initiated a formal consultation with NMFS for 37 of these 55 pesticides.
Like most of the prior BiOps, the latest NMFS BiOp recommends that EPA require the affected pesticide registrants to adopt buffer zones and other mitigation measures. The scientific methodology underlying the NMFS BiOps has been sharply criticized by industry and questioned by EPA. EPA has not yet adopted the measures recommended by NMFS in any of the previous BiOps. The BiOp for the pesticides chlorpyrifos, diazinon, and malathion was vacated and remanded to NMFS by the Fourth Circuit Court of Appeals on February 21, 2013. That decision was based in part on use of implausible assumptions in the NMFS model and on the decision of NMFS to recommend uniform buffer zones without regard to site-specific factors. Industry has criticized the latest BiOp on similar grounds. Some may also ask why NMFS did not utilize methodology like that recommended in 2013 by a panel of the National Academy of Sciences, but NMFS states that consultations with other agencies concerning a process to implement the NAS recommendations are still pending.
On December 19, 2014, EPA opened the public comment period for 19 registration reviews. 79 Fed. Reg. 75801. The registrations are for: 3-methyl-cyclohexen-1-one (Case 6074); alkyl trimethylenediamines (ATMD) (Case 3014); boscalid (Case 7039); dikegulac sodium (Case 3061); ethoxyquin (Case 0003); fenpyroximate (Case 7432); flonicamid (Case 7436); fluazifop butyl, isomers (Case 2285); flufenpyr-ethyl (Case 7262); HHT (Grotan) (Case 3074); metolachlor & s-metolachlor (Case 0001); napthaleneacetic acid (Case 0379); oxadiazon (Case 2485); oxyfluorfen (Case 2490); pentachlorophenol (Case 2505); sodium fluoride (Case 3132); sulfonic acid salts (Case 7619); triclopyr (Case 2710); and yellow mustard seed (Case 7618). EPA will accept comments and information until February 17, 2015.
