On May 19, 2015, the U.S. Environmental Protection Agency (EPA) announced that it issued a conditional registration for a nanosilver-containing antimicrobial pesticide product named “NSPW-L30SS,” or “Nanosilva.” This is the second nanosilver registration issued by EPA and reflects the Agency’s growing expertise in addressing, processing, and approving nanopesticide registration applications. According to EPA, the product will be used as a non-food-contact preservative to protect plastics and textiles from odor- and stain-causing bacteria, fungi, mold, and mildew. Items to be treated include household items, electronics, sports gear, hospital equipment, bathroom fixtures, and accessories. EPA based its decision “on its evaluation of the hazard of nanosilver after reviewing exposure data and other information on nanosilver from the applicant, as well as data from the scientific literature.” EPA states that these data show that treated plastics and textiles release “exceedingly small amounts of silver.” Based on this evaluation, EPA “determined that NSPW-L30SS will not cause unreasonable adverse effects on people, including children, or the environment and that it would be beneficial because it will introduce less silver into the environment than competing products.” EPA notes that it is requiring the company “to generate additional data to refine the Agency’s exposure estimates.” According to EPA, it will post a response to comments received on its 2013 proposed registration decision document, as well as the current decision document, in the rulemaking docket.

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.

On March 1, 2015, the U.S. Environmental Protection Agency (EPA) released the 11th Annual Report on EPA’s implementation of the Pesticide Registration Improvement Extension Act (PRIA 3) that is required under Section 33(k) of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA).
This annual report details changes in processes, practices, and policies for Fiscal Year (FY) 2014 that ran from October 1, 2013, through September 30, 2014. The report is divided into different sections related to: (1) pesticide registration service fees; (2) maintenance fees; and (3) process improvements in the pesticide program; all of which can be accessed on EPA’s website at the below links. Specifically, the report covers the following topics:
Pesticide Registration Service Fees
* Fees Collected, Waived, Exempted and Expended
o Pesticide Worker Protection
o Partnership Grants
o Progress in Meeting Decision Times
* Fees Collected and Expended
o Expedited Processing FIFRA Section 3(c)(3)(B)
o Pesticide Reevaluation Programs
Process Improvements in the Pesticide Program
* Pesticide Reevaluation Programs
* Information Technology and Labeling
* Science Review/Assessment Improvements
EPA’s report addressing process improvements in the pesticide program discusses several areas where EPA believes its registration programs have improved, either through increased efficiency, consistency, and/or transparency. The areas discussed are:
* EPA’s use of the “Lean” business model to improve business processes;
* Delegation of authority to EPA’s Biopesticides and Pollution Prevention Division (BPPD) to expedite fast track and notification actions to reduce approval times and the number of actions in backlog status;
* Biopesticide Industry Alliance Registration Workshops to improve quality of application submissions;
* Release of testing guidelines to clarify scenarios under which efficacy testing at the lower certified limit is needed;
* Reduction of registered products for which EPA is taking action under the Antimicrobial Testing Program;
* Continued crop grouping regulations to save resources and reduce the number of required residue studies;
* Establishment of a Pre-decisional Determination Due Date to provide adequate time to reach agreement with the registrant on required label changes prior to EPA approving the label; and
* International work sharing to assist in individual country registration decisions while striving to harmonize regulatory decisions with global partners.
With regard to EPA’s review of electronic labels, EPA states the following:
1. Of approximately 6,300 labels submitted to EPA in FY 2014, almost half included an electronic label. Comparing the statistics from FY 2011 to FY 2014 reveals a steady increase of approximately 10 percent each year in the percentage of labels submitted in electronic format.
2. The use of electronic label review software varies significantly across the three regulatory divisions with the Registration Division reporting the highest use, the Antimicrobials Division reporting moderate use, and BPPD the lowest use.
PRIA 3 is effective from October 1, 2013, through September 30, 2017.

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.

Center for Food Safety v. EPA is a case in the U.S. Court of Appeals for the 9th Circuit (9th Circuit) that consolidates two petitions for review of a decision by the U.S. Environmental Protection Agency (EPA) to register the new herbicide product Enlist Duo for use in six Midwestern states. A group of non-governmental organizations filed one of the petitions and the Natural Resources Defense Council (NRDC) filed a separate petition. Enlist Duo combines the active ingredients glyphosate and 2,4-D. The registrant Dow AgroSciences (Dow) has intervened in the case. The petitioners focus primarily on the purported failure of EPA to consider properly the effects of Enlist Duo on certain endangered species.
Each petitioner has now filed a motion to stay the EPA action registering Enlist Duo due to Endangered Species Act (ESA) challenges. The first stay motion filed by NRDC is based primarily on the risk to monarch butterflies, and that stay motion has now been fully briefed. The other petitioners filed a separate stay motion focusing on whooping cranes and Indiana bats, but they waited until two weeks after EPA and Dow filed their briefs opposing the first stay motion. Before either stay motion was filed, Dow filed a motion seeking transfer of the case to the D.C. Circuit Court of Appeals. Arguing that the two independent successive stay motions were abusive, Dow later filed a motion to hold the briefing on the second stay motion in abeyance, pending a ruling on its transfer motion.
The 9th Circuit denied Dow’s motion to hold the briefing on the second stay motion in abeyance only three days later. This procedural ruling does not dispose of the underlying transfer motion, but it does suggest that the court is not inclined to transfer the case. If the case is not transferred, the court will ultimately consider and rule on both pending stay motions. The court’s interim order does not suggest how it views the pending stay motions. The petitioners have a heavy burden to show both a substantial likelihood of success on the merits and irreparable harm to obtain the requested interim relief. EPA and Dow contend that the petitioners have not established either of these things. Overall, this ESA challenge to a new genetically modified organism (GMO) product may indicate a new front in the ESA litigation arena, since new products have generally not been challenged under ESA requirements. 2,4,-D itself is not a new herbicide, so this case is not quite a challenge to a totally new active ingredient; such a challenge was made recently in the case of cyantraniliprole. CBD, et al. v. EPA, No. 14-00942 (D.D.C. filed Oct. 10, 2014). Challenges to new active ingredients and GMO products, however, could threaten to hinder the introduction of new products into the marketplace.

The California Department of Pesticide Regulation (DPR) has extended, from February 27, 2015, to Friday, March 13, 2015, the submission of written comments following DPR’s January 14, 2015, Registration Fee Workshop where DPR discussed the potential increase in registration fees for pesticide products pursuant to Food and Agricultural Code (FAC) § 12812(a).
Under the proposal, DPR would increase fees for applications and renewals from $750 to $1,150, decrease fees for certain label amendments supported by scientific data from $100 to $25, and create a new fee of $25 for label amendments not supported by scientific data, including substantive label amendments, non-substantive label amendments, label changes required by the U.S. Environmental Protection Agency or any other federal or state agency, amendments to the formulation of the pesticide product, and notifications.

Spray drift and volatilization issues increasingly are significant issues in pesticide product risk assessments. Earlier this year, the U.S. Environmental Protection Agency (EPA) issued drafts of key guidance documents, which focused on issues that were key in the chlorpyrifos petition response, and more recently, at least one registration review decision that reflects current and still evolving EPA policy on spray drift and volatilization issues.
How potential for spray drift and for volatilization are identified and then managed are likely to be key elements of ongoing and future risk assessments underlying forthcoming EPA registration and reregistration, with significant potential impact on these decisions. Registrants should monitor closely the policies, EPA decisions implementing them, and their potential impact on their products, particularly given the public interest in these issues.
The EPA documents issued in the past eight or so months are significant, particularly given the years of controversy and difficulty in past attempts to propose a clear and “simple” definition of “drift.” The perception by some advocacy groups is that EPA is not adequately addressing alleged harms posed by drift, and resulting appeals for court intervention will undoubtedly complicate the matrix of considerations influencing EPA’s policy. These reasons alone make monitoring the development of these policies critical for registrants.

In a wide-ranging decision issued on August 13, 2014, in Center for Biological Diversity v. EPA (N.D. Cal.) (often referred to as the “Mega ESA” case), Magistrate Judge Spero has dismissed most of the claims by the Plaintiffs that the U.S. Environmental Protection Agency (EPA) failed to consult or to reinitiate consultation under Endangered Species Act (ESA) Section 7(a)(2) in connection with EPA’s registration under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) of a variety of pesticides. This decision is significant not only for its findings concerning judicial review of consultations under the ESA, but also for the potential effect on challenges to generic reregistration decisions, and on individual product actions based on those EPA decisions. Registrants should carefully consider the impact of this decision on potential challenges to EPA actions involving their products. A copy of the decision is available online.
The ESA claims that were dismissed fall in three principal categories: (1) claims concerning Reregistration Eligibility Decisions (RED) for which the general six-year statute of limitations has expired; (2) claims concerning REDs that are reviewable only in the Court of Appeals under FIFRA Section 16(b) and that were not brought in that court within the applicable 60-day period; and (3) claims based solely on Plaintiffs’ allegations that EPA retains ongoing discretionary control over pesticide registration. Claims by the Plaintiffs that currently survive this decision, at least pending further submissions by the Parties, include claims concerning EPA’s reregistration of specific pesticide products, and claims concerning EPA’s failure to reinitiate consultation for any pesticidal active ingredients that were subject to prior Biological Opinions issued by the Fish and Wildlife Service (FWS) for which the process of reregistration is not yet complete.

On July 7, 2014, the Natural Resources Defense Council (NRDC) filed with the U.S. Environmental Protection Agency (EPA) a petition requesting that EPA commence a Special Review for the neonicotinoid pesticides, including six specific active ingredients (dinotefuran, acetamiprid, clothianidin, thiacloprid, imidacloprid, and thiamethoxam), based on the risk that NRDC believes this class of compounds poses to honey bees and native bees. In the petition, NRDC alleges that neonicotinoids “may suppress bee immunity, disrupt brood cycles, impair foraging behavior by interfering with memory and learning, and cause disorientation, preventing bees from finding their way back to the hive.” By submitting this petition, NRDC effectively asks that EPA expedite the evaluation of the effect of this class of active ingredients on pollinators that EPA already intends to undertake as part of the Registration Review process required by Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) Section 3(g), 7 U.S.C. § 136a(g). A copy of the petition is available online.
