On July 20, 2017, the Trump Administration released its 2017 Unified Regulatory Agenda.  The U.S. Environmental Protection Agency’s (EPA) Agency Rule List included several pesticide rulemakings in the proposed rule stage, as well as the Certification of Pesticide Applicators rulemaking that is in the final rule stage.  The five items in the proposed rule stage are:

  1. RIN 2015-AA00:  Revision of Procedural Rules for Hearings on Cancellations, Suspensions, Changes in Classifications, and Denials of Pesticide Registrations.  The agenda states that this proposed rulemaking is a “revision of the Rules of Practice governing the conduct of licensing adjudications under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA).”   The issuance of the proposed rule is scheduled for January 2018.
  2. RIN 2070-AK00:  Pesticides; Technical Amendments to Data Requirements.  The agenda states that to satisfy one of the commitments in a settlement agreement reached with the American Chemistry Council (Docket ID Number EPA-HQ-OPP-2008-0110-0139), EPA is proposing a correction pertaining to the 200 parts per billion (ppb) level described in 40 C.F.R. Section 158.2230(d) that was originally used by the U.S. Food and Drug Administration with respect to the “concentration of residues in or on food for tiering of data requirements for indirect food use biocides.”  Through this rulemaking, the agenda states that EPA intends to “clarify that the 200 ppb level is based on total estimated daily dietary intake for an individual and not on the amount of residue present on a single food.”   The issuance of the proposed rule is scheduled for July 2017.
  3. RIN 2070-AK06:  Pesticides; Procedural Rule Amendment; Requirement for Certain Pesticide Actions to Publish Notices in the Federal Register.  In the agenda, EPA states that as the as the Federal Register is “no longer the most cost effective or efficient way for providing notice or sharing information with the public,” it is considering changing the way that it provides notice on or shares information with the public -- specifically, by no longer publishing certain information in the Federal Register, but instead providing the same information on a consolidated website which the agenda states “will be more accessible to the public and other interested parties, as well as a more cost effective and efficient mechanism for providing timely updates.”  The agenda lists the following kinds of notification it is considering making this change regarding: (1) reregistration of a pesticide product with a new active ingredient or new use; (2) announcing approvals of specific, quarantine and public health exemptions; and (3) Summaries of certain state registrations.  For Registration Review, the agenda state that EPA “intends to announce availability of the documents that are currently announced in the Federal Register on the EPA's Registration Review Website.”  For notices of availability announced in the Federal Register, the agenda states that “EPA intends to direct the public to a case-specific docket on Regulations.gov to view pertinent registration review documents and provide comment.”  The issuance of the proposed rule is scheduled for April 2018.
  4. RIN 2070-AK40:  Extension of Compliance Date(s); Agricultural Worker Protection Standard.  As reported in our memoranda summarizing the Worker Protection Standard (WPS) final rule, EPA Publishes Worker Protection Standard Final Rule, the WPS final rule was issued on November 2, 2015, but has not yet been made effective.  More information on the delay of its effective date is available in our blog item EPA to Delay Agricultural WPS Indefinitely; Cites Issues with Guidance and Training.  This proposed rulemaking will adjust the compliance date.  The issuance of the proposed rule is scheduled for July 2017 and the issuance of the final rule is scheduled for November 2017.
  5. RIN 2080-AA13:  Updates to 40 C.F.R. § 26 Subpart K to reflect recent changes to 40 C.F.R. Subpart A (The Common Rule).  As reported in our blog item Federal Agencies Announce Revision to Modernize Federal Policy for the Protection of Human Subjects, on January 19, 2017, EPA, together with a host of other federal agencies, released a final rule to modernize, strengthen, and make more effective the Federal Policy for the Protection of Human Subjects that was originally promulgated as a Common Rule in 1991, and is now codified in 40 C.F.R. § 26, Subpart A.  These revisions, scheduled to become effective on January 19, 2018, will create a conflict within some of the EPA-specific subparts, in particular, Subpart K of 40 C.F.R. 26 (Basic Ethical Requirements for Third-Party Human Research for Pesticides Involving Intention Exposure of Non-Pregnant, Non-Nursing Adults) which regulates third party pesticide research.  The agenda states that this proposed rulemaking is “intended to resolve proposed rulemaking discrepancies created by the recent revision to Subpart A, and will not alter the fundamental protections for human subjects, including vulnerable populations.”  The issuance of the proposed rule is scheduled for January 2018.

The two items in the final rule stage are:

  1. RIN 2070-AJ20:  Pesticides; Certification of Pesticide Applicators.  As reported in our memoranda summarizing the Certification of Pesticide Applicators’ final rule, Final EPA Rule Requires Stronger Standards for Applying Riskiest Pesticides, the final rule was issued on January 4, 2017.  More information on the delay of its effective date is available in our blog item EPA Delays Effective Date of Certification of Pesticide Applicators Final Rule.  On June 2, 2017, a Federal Register publication was issued that delayed the effective date until May 22, 2018.
  2. RIN 2070-AK13:  Procedural Rule to Remove Obsolete Information.  The agenda states that this final rule will remove information from EPA’s existing pesticide regulations that is now out of date or obsolete and will “provide clearer and more reliable information to those seeking to register a pesticide product.”  The agenda further states that as rulemaking is intended to be a non-substantive, procedural rulemaking “since the EPA does not intend to make any substantive changes to the existing requirements,” EPA is considering issuing this as a final rule and not going through the notice and comment period.  The issuance of the final rule is scheduled for January 2018.

Commentary

Much of the work noted emphasizes potential procedural efficiencies and clarifications.  The potential move to more announcements on the websites and away from the Federal Register is, at least in part, likely intended as a cost-saving measure.  It is also a change that will be closely watched.  For example, in recent years, EPA has seen registrations challenged based on assertions of an alleged lack of appropriate notice concerning the receipt or processing of registration applications, and these past challenges will likely influence any new procedures that EPA may adopt. 

Of more interest is the new Administration’s call for suggestions of what rules or policies should be changed as part of a broader push for economic growth and less regulatory costs, which may result in more substantive regulatory changes and some likely controversial decisions about what rules or programs will be modified or eliminated -- but that exercise is not part of this announcement.  The delay in the compliance date for the WPS regulation is more substantive, but changes that may be proposed have not yet been announced.

On June 30, 2017, the U.S. Court of Appeals for the D.C. Circuit issued its opinion in Center for Biological Diversity (CBD), et al. v. U.S. Environmental Protection Agency (EPA), Case No. 14-1036, resolving jurisdictional and substantive issues following complaints alleging that EPA violated Section 7(a)(2) of the Endangered Species Act (ESA) by failing to make an effects determination or to consult with the U.S. Fish and Wildlife Service (FWS) or the National Marine Fisheries Service (NMFS) before registering cyantraniliprole (CTP) under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA).

Regarding the jurisdictional issue and the appropriate court in which to bring such a challenge, the U.S. District Court for the District of Columbia on May 14, 2015, had dismissed the ESA complaint of CBD, the Center for Food Safety, and the Defenders of Wildlife (Conservation Groups), finding that the Conservation Groups’ “Complaint gives rise to an ‘actual controversy as to the validity’ of the FIFRA Registration Order and is therefore governed by that Act’s jurisdictional grant.”  The D.C. Circuit affirmed the U.S. District Court’s ruling to dismiss the ESA petition on jurisdictional grounds, concluding that FIFRA “grants the court of appeals exclusive jurisdiction to review an ESA claim that is ‘inextricably intertwined’ with a challenge to a pesticide registration order.”

The D.C. Circuit also, however, granted the Conservation Groups’ FIFRA petition, finding that EPA registered CTP without having made an effects determination or consulting with the FWS and/or the NMFS as required under ESA Section 7(a)(2).  The court remanded the case to EPA for further proceedings, but allowed the CTP registration order to remain in effect until it is replaced by an order consistent with the court’s opinion.

Considering the growing number of complaints that allege a failure to consult with the FWS and/or the NMFS under the ESA, this decision could have broad reaching implications for how these complaints are filed and reviewed.

Background

On February 29, 2012, EPA announced that it had received applications to register pesticide products containing CTP under FIFRA.  On June 6, 2013, EPA announced its proposal to register CTP as a pesticide under FIFRA.  As part of its review, EPA prepared an “Environmental Fate and Ecological Risk Assessment for the Registration of the New Chemical Cyantraniliprole” in which EPA states that CTP is “highly toxic or very highly toxic” to multiple taxonomic groups, including terrestrial invertebrates such as butterflies and beetles.

On January 24, 2014, EPA registered CTP as a pesticide under FIFRA and approved fourteen end-use products containing CTP.  At issue in this case was EPA’s decision to register CTP without having made an effects determination or consulting with the FWS and/or the NMFS as required by ESA Section 7(a)(2) and implementing regulations (50 C.F.R. § 402.13-14).

Under the ESA citizen-suit provision, “any person” may “commence a civil suit on his own behalf … to enjoin any person, including the United States and any other governmental instrumentality or agency … who is alleged to be in violation of any provision of this chapter or regulation issued under the authority thereof.” 16 U.S.C. § 1540(g)(1).  “The district courts … have jurisdiction” of ESA citizen suits, id., but no action may be commenced “prior to sixty days after written notice of the violation has been given to the Secretary, and to any alleged violator.” Id. § 1540(g)(2)(A)(i).

FIFRA’s citizen-suit provision at 7 U.S.C. § 136n(b) provides the federal circuit court with exclusive jurisdiction to affirm or set aside an EPA pesticide registration order following a public hearing, provided a challenge is filed within 60 days of the registration decision.

With potentially conflicting statutory provisions regarding the court in which to file a complaint and the timing to do so, the Conservation Groups initiated two actions:  a complaint against EPA in D.C. District Court under the ESA’s citizen-suit provision; and a petition for review in D.C. Circuit Court pursuant to FIFRA’s citizen-suit provision.

Jurisdictional Issues

The D.C. Circuit first addressed the jurisdiction issue, which involved a determination of standing and a resolution of the “dueling jurisdictional provisions of the ESA and of FIFRA.”

On the issue of standing, the D.C. Circuit found that petitioners did in fact have standing, as not only did EPA make procedural omissions through “its failure to make an effects determination and to consult,” but the plaintiffs show that EPA’s failure affected the plaintiffs’ members’ “concrete aesthetic and recreational interests.” 

With regard to the appropriate court in which to bring this claim, the D.C. Circuit found that “FIFRA vests the courts of appeals with exclusive jurisdiction over controversies arising from an EPA pesticide registration, so long as, inter alia, registration follows a public hearing.”  The court thus also found:

  • Because FIFRA’s grant of exclusive jurisdiction to the court of appeals to review registration orders is more specific than the ESA’s citizen-suit provision, we believe the Conservation Groups must bring their ESA section 7(a)(2) challenge to us if 7 U.S.C. § 136n(b) is satisfied.  And the Conservation Groups do satisfy the requirements of 7 U.S.C. § 136n(b): they are adversely affected by the registration of CTP; they challenge the validity of the CTP registration order based on the EPA’s failure to make an effects determination and to consult; and their challenge comes after a “public hearing” by way of three notice and comment periods.  We therefore have “exclusive jurisdiction” to review their claim under FIFRA and the district court correctly dismissed their ESA citizen suit. (citations omitted).

Merits

While the ESA citizen suit was dismissed, the FIFRA citizen suit remained under the D.C. Circuit’s exclusive jurisdiction and review.  The court found that EPA violated ESA Section 7(a)(2) by registering CTP before making an effects determination or consulting with the FWS or the NMFS.

Significantly, the court decided to remand the case to EPA for further proceedings without vacating the CTP registration.  The court stated that remand without vacatur is appropriate in this case because “[n]otwithstanding the EPA’s failure to make an effects determination and to engage in any required consultation, it did not register CTP in total disregard of the pesticide’s potential deleterious effects; indeed, the Conservation Groups themselves rely heavily on the EPA’s ‘Ecological Risk Assessment for the Registration of the New Chemical Cyantraniliprole.’”  The court further stated that “allowing the EPA’s CTP registration order to remain in effect until it is replaced by an order consistent with our opinion will maintain ‘enhanced protection of the environmental values covered by the CTP registration order.’”

Commentary

This case is significant in at least two respects and should have implications in other cases being brought under ESA and FIFRA citizen suit petitions.  First, the court provides the same answer concerning the “dueling jurisdictional provisions of the ESA and of FIFRA” as prior decisions in the Ninth Circuit, finding that FIFRA’s jurisdictional grounds take precedence and that the Courts of Appeal have exclusive jurisdiction to review cases claiming ESA violations in the context of an approved FIFRA pesticide registration.  The court found the Conservation Groups’ arguments to the contrary “unavailing,” including but not limited to their argument that the public notice and comment periods that were provided did not constitute a “public hearing” under FIFRA Section 16(b) as well as their argument that the ESA challenge was not “inextricably intertwined” with FIFRA, even though the Conservation Groups were challenging the CTP registration order itself.  It also is significant that the court, while remanding the registration order to EPA for further actions under the ESA, did not immediately vacate the existing CTP registration order.

Some observers of the extensive ESA-FIFRA litigation over recent years wondered whether the CTP registrations would be vacated once challenged for conformity to ESA requirements.  EPA effectively admitted that it did not follow the full consultation process with FWS and NMFS, in this case substituting a relative risk argument that CTP was an improvement that would provide more species protection compared to the compounds it is expected to replace in the marketplace.  The remand without vacatur does not resolve what some have called the “train wreck” scenario, where the need to complete ESA consultation, combined with time and resource constraints at the respective agencies, will result in a virtual freeze on new pesticide product registrations.  The court makes it clear that, if EPA makes an affirmative ESA effects determination for CTP, consultation with the FWS and/or the NMFS must follow.

On June 14, 2017, the U.S. Environmental Protection Agency (EPA) issued a Federal Register notice announcing the availability of a final test guideline, Laboratory Product Performance Testing Methods for Bed Bug Pesticide Products; OCSPP Test Guideline 810.3900, part of a series of test guidelines established by the EPA’s Office of Chemical Safety and Pollution Prevention (OCSPP) for use in testing pesticides and chemical substances.  82 Fed. Reg. 27254.  EPA states that this test guideline provides “guidance for conducting a study to determine pesticide product performance against bed bugs, and is used by EPA, the public, and companies that submit data to EPA,” and “recommendations for the design and execution of laboratory studies to evaluate the performance of pesticide products intended to repel, attract, and/or kill the  common bed bug (Cimex lectularius) in connection with registration of pesticide products under the [Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA)].”  EPA states that this guidance applies to products “in any formulation such as a liquid, aerosol, fog, or impregnated fabric, if intended to be applied to have a pesticidal purpose such as to attract, repel, or kill bed bugs.”  This guideline provides appropriate laboratory study designs and methods for evaluating the product performance of pesticides against bed bugs and includes statistical analysis and reporting.

EPA issued the draft guideline on February 14, 2012.  This original document was the subject of FIFRA Scientific Advisory Panel (SAP) review conducted on March 6-7, 2012.  EPA indicates that the final version of the guideline reflects revisions to the original draft based on comments from the SAP and the public.  EPA states that the revisions include the following:

  • Decreasing the number of individuals and replicates tested;
  • Rescinding the recommendation to test each field strain for its resistance ratio; and including a resistance management statement;
  • Clarifying the agency's Good Laboratory Practices (GLP) requirements;
  • Reducing the recommended length of time individuals are exposed to insecticides;
  • Recommending individuals to be observed up to 96 hours after treatment; and
  • Revising the statistical analyses recommendations.

EPA has also placed two other relevant documents in the docket:

On May 30, 2017, the U.S. Court of Appeals for the Ninth Circuit responded to two petitions for review of the U.S. Environmental Protection Agency’s (EPA) conditional registration of a nanosilver pesticide product and vacated the conditional registration.  NRDC v. EPA, No. 15-72308.  The Natural Resources Defense Council (NRDC) as well as the Center for Food Safety (CFS) and the International Center for Technology Assessment (ICTA) filed petitions in 2015 asking the court to set aside EPA’s final order granting a conditional registration for a nanosilver-containing antimicrobial pesticide product named NSPW-L30SS (NSPW).  The court vacated the conditional registration because, according to the court, “EPA failed to support its finding that NSPW is in the public interest.” 

When EPA granted the conditional registration, EPA did so on the basis that NSPW had a lower application rate and a lower mobility rate when compared to conventional-silver pesticides, and thus had the potential to reduce environmental loading and risk caused by silver release.  Petitioners disputed these facts.  While the court found that substantial evidence supports EPA’s findings that NSPW has lower application and mobility rates, the court agreed that the third premise, that current users of conventional-silver pesticides will switch to NSPW and/or that NSPW will not be incorporated into new products, “impermissibly relies on unsubstantiated assumptions.”  According to the court, EPA cites no evidence in the record to support its assumption that current users of conventional-silver pesticides will switch to NSPW (“the substitution assumption”), but contends that it will occur as a “logical matter.”  The court states that the lack of evidence supporting the substitution assumption is problematic in light of EPA’s other unsupported assumption, that there will be no new products.  The court notes that EPA assumes current users of conventional-silver pesticides will switch to NSPW because of its benefits, but that these same benefits will not prompt manufacturers to incorporate NSPW into new products.  EPA could have proved these assumptions, but without evidence in the record to support the assumptions, the court states that it “cannot find that the EPA’s public-interest finding is supported by substantial evidence as required by [the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA)].”  According to the court, the public interest finding is an “essential prerequisite to conditional registration,” and EPA failed to support that finding for NSPW with substantial evidence.  The court vacated the conditional registration in whole, and did not consider the remaining issues raised by petitioners.

On March 29, 2017, U.S. Environment Protection Agency (EPA) Administrator Pruitt signed an order denying the September 2007 petition of the Pesticide Action Network North America (PANNA) and the Natural Resources Defense Council (NRDC) requesting that EPA revoke all tolerances and cancel all registrations for the pesticide chlorpyrifos.  This is the latest EPA action in a long and contentious battle concerning chlorpyrifos tolerances and registrations, and is likely not the end of this story.

EPA’s decision denying the petition addresses each of the petition’s ten claims and the history of EPA’s review and responses to those claims.  Much attention will be paid to the order’s discussion of three of the claims, which the order states all relate to the same issue:  “whether the potential exists for chlorpyrifos to cause neurodevelopmental effects in children at exposure levels below EPA’s existing regulatory standard (10% cholinesterase inhibition).”  The order states that because “Congress has provided that EPA must complete registration review by October 1, 2022,” and because EPA has “concluded that it will not complete the human health portion of the registration review or any associated tolerance revocation of chlorpyrifos without first attempting to come to a clearer scientific resolution” on the issues concerning potential neurodevelopmental effects in children, EPA is denying the claims, given the Ninth Circuit Court of Appeals’ August 12, 2016, order that “made clear” that further extensions to the March 31, 2017, deadline for responding to the petition would not be granted.  EPA states that the “science addressing neurodevelopmental effects remains unresolved,” and “further evaluation of the science during the remaining time for completion of registration review is warranted to achieve greater certainty as to whether the potential exists for adverse neurodevelopmental effects to occur from current human exposures to chlorpyrifos.”

The order will become effective as soon as it is published in the Federal Register.  More information on the prior proceedings concerning this matter is available on our blog under key phrase chlorpyrifos.

Commentary

This decision by EPA under the Trump Administration to deny the petition is not surprising, given the rhetoric of reducing regulatory burdens and the need to stop regulatory “overreach” by agencies like EPA which has been accused of making politically driven decisions.  EPA's press release captures this, quoting Administrator Pruitt stating (in part):  "By reversing the previous Administration’s steps to ban one of the most widely used pesticides in the world, we are returning to using sound science in decision-making -- rather than predetermined results.”

EPA has, however, “kicked the can down the road” to some extent on the key science issue -- whether EPA appropriately evaluated epidemiology studies which reported that exposures to the pesticide had adverse neurological impacts on infants and children -- an issue that affects not only chlorpyrifos, but the other organophosphates (OP) that EPA has concluded are subject to a Food Quality Protection Act (FQPA) 10X factor based on these studies.  (See EPA’s September 15, 2015, Literature Review on Neurodevelopment Effects & FQPA Safety Factor Determination for the Organophosphate Pesticides.)    

The Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) Scientific Advisory Panel (SAP) members who reviewed EPA’s approach, based on these studies with regard to chlorpyrifos, generally had concerns with its proposed approach.  When EPA nonetheless issued its renewed call for revocation of the tolerances in November 2016, eight days after the Presidential election, it was seen by some as partly (if not fully) driven by a “political” calculus which ignored the lack of support of the FIFRA SAP. 

The November 2016 proposal was based on more than the epidemiology studies which have proven controversial.  At the same time, EPA’s arguments in the November notice relied on some of the earlier findings about  the studies and FIFRA SAP’s review to fashion a “hybrid” approach which, not surprisingly, supported EPA’s previous conclusions.

This has led to charges of “politics over science” on all fronts, but in responding to the court deadline for a final decision by March 31, 2017, EPA has now declared it does indeed need more time to resolve the science issues, and argues that the general registration review process, with the chlorpyrifos review scheduled for 2022, gives EPA more time than what the court imposed.  EPA has concluded that if a decision is needed now, the required burdens have not been met to change the current status of the pesticide.  The order states:

  • Following a review of comments on both the November 2015 proposal and the November 2016 notice of data availability, EPA has concluded that, despite several years of study, the science addressing neurodevelopmental effects remains unresolved and that further evaluation of the science during the remaining time for completion of registration review is warranted to achieve greater certainty as to whether the potential exists for adverse neurodevelopmental effects to occur from current human exposures to chlorpyrifos.  EPA has therefore concluded that it will not complete the human health portion of the registration review or any associated tolerance revocation of chlorpyrifos without first attempting to come to a clearer scientific resolution on those issues.

EPA has determined it needs more time, however frustrating that may be, to sort out the science.  As such, it is allowing chlorpyrifos use to continue, but objections to EPA’s decision are expected by the petitioners who originally pushed for the tolerance revocations.  The effect on other OPs with regard to the application of the FQPA uncertainty factor is unclear, at best.  The science debate will rage on, with no clear timeline or process for how the ultimate resolution of these questions will be “final.”  This political and legal back-and-forth may become the new normal for the Trump Administration as it seeks to balance a more “business friendly” regulatory approach with the stringent requirements of the statutory duties of underlying authorizing legislation across all of EPA’s programs.

The following documents have been filed in the Anderson v. McCarthy proceedings in the U.S. District Court for the Northern District of California:  (1) U.S. Environmental Protection Agency’s (EPA) Notice of Motion and Motion for Summary Judgment; (2) Defendant-Intervenors CropLife America, et al.’s Notice of Motion and Motion for Summary Judgment; and (3) Plaintiffs’ Memorandum of Points and Authorities in Support of Motion for Summary Judgment.

EPA’s documents are of particular interest to those who have been following this case and are concerned about the assertions in the case regarding the treated article exemption.  In its motion, EPA argues that the Ninth Circuit lacks jurisdiction to hear Plaintiffs’ claims, as the “EPA guidance document they challenge is not a judicially reviewable agency action -- much less a final action -- regarding the regulatory status of treated seed,” and Plaintiffs “have not identified any discrete, mandatory duty or action that EPA has failed to perform under [the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA)].” 

EPA’s main arguments in support of its motion include:

  1. Plaintiffs have not identified any final agency actions.  The Inspection Guidance is not an agency action, and even if the Inspection Guidance were an agency action, it is not final.
  2. Count II (Plaintiffs’ allegation of EPA’s failure to regulate and enforce FIFRA with respect to pesticide-treated seeds) must be dismissed because there is no nondiscretionary duty identified by Plaintiffs that is unreasonably delayed or unlawfully withheld.
  3. Enforcement of FIFRA is a discretionary action not subject to review.

In its motion, Defendant-Intervenors argue:  “Each of Plaintiffs’ claims constitutes an impermissible programmatic attack on EPA’s existing pesticide regulatory program --specifically, the interplay between EPA’s regulation of pesticides registered to be applied as seed treatments and what Plaintiffs characterize as its categorical application of the treated article exemption to the treated seed.  As a result, each of these claims is non-justiciable as a matter of law, entitling Defendants to summary judgment in their favor.”  Defendant-Intervenors note that pesticides used for seed treatments are subject to “rigorous, scientifically robust review and approval under FIFRA,” making Plaintiffs’ attempt to impose a regulatory process “entirely duplicative of EPA’s existing exercise of its authority under FIFRA, while having no impact on human health or environmental safety.”

Plaintiffs’ memorandum sets forth its arguments for why the court should “find in favor of Plaintiffs on their four claims for relief:  that EPA failed to enforce FIFRA against an entire class of pesticides; that EPA improperly amended the treated article exemption without following proper [Administrative Procedure Act (APA)] rulemaking procedures; that EPA’s exemption of neonicotinoid-coated seeds was ultra vires and/or arbitrary and capricious under the APA; and that EPA’s labeling requirements for unregistered pesticide-coated seed bags was arbitrary and capricious under the APA and FIFRA.”  Specifically, Plaintiffs address why they believe EPA has failed to enforce FIFRA against neonicotinoid-coated seeds, why this asserted failure amounts to what they believe is “an unlawful abdication of [EPA’s] statutory responsibilities” and why they believe “EPA’s failure to enforce FIFRA against neonicotinoid-coated seeds and pesticidal dust-off is a ‘consciously and expressly adopted general policy,’ which ‘amounts to an abdication of its statutory responsibilities’ that this Court has the power to remedy.”

A hearing on EPA’s motion was set for October 27, 2016, but due to scheduling conflicts has been rescheduled for November 3, 2016.  It will be important to monitor the court’s consideration of these important issues closely.   More information on these proceedings can be found in our pesticide blog items District Court Declines to Rule on Jurisdictional Issues in Neonicotinoid Case until Summary Judgment and EPA Requests Dismissal of Complaint For Lack of Subject Matter Jurisdiction.

The threat of the Zika Virus grows every day, and the need for clear information is especially pressing if you are pregnant.  How do you prevent getting infected with the Zika Virus, and what insect repellents are best?  The first question is easy to answer:  public health experts agree that women who are pregnant or who might be pregnant should use insect repellents.  The answer to the second question is not so simple.

I am a former senior official at the U.S. Environmental Protection Agency (EPA), and familiar with how the U.S. evaluates and approves pesticides, which include insect repellents.  It is not easy for the average consumer to know what works and what does not work.  Unfortunately, EPA policies have made this question much more complicated, having made important distinctions between some “natural”-type repellents and other products available in the marketplace.

Years ago, EPA de-regulated a number of natural, non-toxic materials from being subject to the registration requirements of the federal pesticide law (the Federal Insecticide, Fungicide, and Rodenticide Act).  This made sense at the time since garlic, pepper, rotten eggs, vinegar, and other common chemicals are sometimes used as pesticides.  Before de-regulation, these products were also subject to the same requirements as synthetic chemical pesticides with long unpronounceable names (e.g., diethyltoluamide, better known as DEET) which EPA requires to have volumes of efficacy and safety test data.  Being natural does not mean a substance is non-toxic; some natural ingredients are fully evaluated and widely used.  But in the interest of efficient use of resources EPA issued a list of products that could be sold as pesticides, but would not be subject to EPA data requirements and review (EPA calls them “minimum risk pesticides”).

This list of pesticides which are not subject to EPA evaluation, and which are not required to have data which proves they are effective, includes a number of botanical ingredients, such as oil of citronella, geranium, rosemary, peppermint, and many others.  Many of these products can be used as pesticides -- some may work better than others -- and many work for the intended use (example:  rotten eggs, or as EPA refers to them -- “putrescent whole egg solids” -- are used as a deer repellent).

Many of these ingredients have been marketed as “natural” insect repellents, and labeled as “safe” or “non-toxic” using words that will not appear on products where EPA reviews and approves the instructions on the product label.

Here is the bureaucratic distinction which matters greatly to EPA, but will not be understood by consumers:

  • If the repellant label includes “public health claims” -- that it repels mosquitoes that may cause a disease (like Zika Virus or West Nile Virus) -- then the product has to have data showing that it works;
  • If the product just says “repels mosquitoes,” it is not required to have data that shows it is effective, and may very well be ineffective.

Few, if any, humans outside of EPA label experts realize this important distinction:  if there is no health claim on the label, then it is, in effect, a situation of “buyer beware.” 

What remains:  EPA’s deregulation of these products means it is legal to sell products which do not work, as long as the ingredients appear on the EPA minimum risk pesticides list.

Consumer Reports (CR) recently reported in May of this year on studies conducted on repellents.  Their results:

  • Using a “natural” mosquito repellent, with active ingredients such as citronella or clove, lemongrass, or rosemary oils, might seem like a good idea, especially if you’re pregnant or planning to be.
  • But five of the six plant-based repellents we tested…lasted one hour or less against Aedes mosquitoes, the kind that can spread Zika.

Not all repellents with the same ingredient are equally effective, and they found that some formulations of the chemical repellents also do not work for very long in their tests.  Some botanical pesticides are effective and have the public health claims on the label (example:  lemon eucalyptus, a botanical ingredient not on the exempt product list, and CR testing did find it to be effective).

To reduce confusion about what works, EPA for years has struggled to correct the situation by trying to impose changes to the requirements for insect repellents.

Unfortunately, to end the confusion about the difference between “repels mosquitoes” and “repels mosquitoes that can cause the Zika Virus,” EPA has to conduct a rulemaking which requires a long and bureaucratic process to complete.  The good news is that EPA is working on such a solution.  The bad news is that they have been working on it for almost ten years and they still have more work to do.  There are details and petitions and proposals and reasons why it has taken so long, but it is the kind of story that gives bureaucracy a bad name.

With the onset and fears about the Zika Virus, however, EPA should make the needed changes immediately to ensure that consumers are not misled into using products which are not proven effective in repelling mosquitoes. 

From a consumer’s point of view, it really is that simple.  Legally, it is more complicated.  In the meantime, EPA should be loud and clear in its communication about the distinction, even if they cannot take immediate action to reduce the confusion.

On August 12, 2016, a three-judge panel of the Ninth Circuit Court of Appeals issued an order denying the U.S. Environmental Protection Agency’s (EPA) request for an additional six months to decide whether to ban agricultural uses of chlorpyrifos.  The court opted instead to afford EPA a three month extension, stating that “this is the final extension, and the court will not grant any further extensions." 

EPA sought the six month extension on June 29, 2016, to allow time for EPA to complete two scientific analyses that may bear on EPA’s conclusions in the final rule, and to request further public comment before taking final action on a prior proposal to revoke all chlorpyrifos tolerances.  The two analyses that EPA wanted to complete are:  (1) a refined drinking water assessment that may allow EPA “to develop more tailored risk mitigation for some regions of the country,” and (2) an evaluation of the epidemiological data for chlorpyrifos to determine whether EPA should retain the point of departure based on acetylcholinesterase (AChE) inhibition in the proposed rule.

The court concluded that EPA’s request for a six month extension “is not justified in light of EPA’s history in this matter as well as the court’s previous extensions.”  The court stated that EPA’s request was "another variation on a theme 'of partial reports, missed deadlines, and vague promises of future action' that has been repeated for the past nine years,” and that “nothing has changed that would justify EPA’s continued failure to respond to the pressing health concerns presented by chlorpyrifos."

The court ordered EPA to take final action on its proposal to revoke tolerances for chlorpyrifos by March 31, 2017.  A further status report by EPA will be due in November 2016.

EPA’s updated analysis of the epidemiological data for chlorpyrifos will be a matter of considerable interest.  After EPA issued a proposed rule utilizing a point of departure for chlorpyrifos based on AChE inhibition, EPA issued a blanket determination based on the epidemiological data for chlorpyrifos in which EPA decided to retain the Food Quality Protection Act (FQPA) safety factor for all organophosphate (OP) pesticides.  This FQPA determination could cause EPA to conclude that the tolerances for chlorpyrifos must be revoked regardless of the outcome of the refined drinking water assessment. 

EPA later proposed to use an alternative point of departure for chlorpyrifos based on biomonitoring data from one of the chlorpyrifos epidemiology studies, but the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) Scientific Advisory Panel (SAP) met on April 19-21, 2016, and recommended against this new approach.  In its request for an extension, EPA stated that the FIFRA SAP might recommend a “hybrid approach” to adjusting the point of departure for AChE inhibition.  The FIFRA SAP meeting minutes do not appear to include such a hybrid recommendation.

In a related development, EPA has reached an agreement with the Columbia Center for Children’s Environmental Health (CCCEH) regarding the release of raw data from one of the chlorpyrifos epidemiology studies.  During the FIFRA SAP meeting, concerns were raised regarding use of the CCCEH study without access to the underlying raw data.  In an April 19, 2016, letter to Dr. Linda P. Fried, Dean of the Mailman School of Public Health at Columbia University, EPA requested that CCCEH provide access to the underlying data.  In her response dated May 18, 2016, Dr. Fried offered to work with EPA “to determine if we can develop one or more data sets that can be properly de-identified, consistent with our obligation to protect the privacy of our research subjects, and that will also enable EPA to conduct its own analyses in order to address its transparency goals” or, in the alternative, offered to allow EPA staff to review the original data “in a secure data enclave onsite at Columbia.”  In its June 27, 2016, response, EPA stated that the offer to allow EPA staff to review the underlying data at a secure site did not resolve issues concerning the transparency of EPA’s analysis.  This correspondence is available in EPA Docket ID EPA-HQ-OPP-2008-0850. While EPA maintained it is “unnecessary” for CCCEH and EPA to develop redacted data sets, EPA accepted CCCEH’s offer to develop such data sets.

Commentary

EPA’s request for a six month extension was filed on June 29, 2016, two days after it accepted the offer by CCCEH to develop redacted data sets for the CCCEH epidemiology study.  Moreover, the FIFRA SAP meeting minutes issued on July 20, 2016, do not appear to provide the guidance that EPA had expected concerning a potential “hybrid” approach to adjusting EPA’s proposed point of departure for AChE inhibition.

Given the lesser extension granted by the court, it is questionable whether EPA will have sufficient time to review adequately the redacted underlying data sets offered by CCCEH, or even to determine whether those redacted data sets are adequate for this review, and to make any determination based on such data before EPA issues a supplementary proposal based on the refined drinking water assessment and the updated epidemiology assessment.  The court has stated that it will entertain no further extension requests, so EPA must complete its work expeditiously to allow time for comment before final action is due on March 31, 2017.
