On October 22, 2014, the U.S. Environmental Protection Agency (EPA) requested public comment on a proposal to remove 72 chemicals from its list of substances approved for use as inert ingredients in pesticide products. EPA reportedly is responding to petitions submitted by the Center for Environmental Health, Beyond Pesticides, Physicians for Social Responsibility, and others that have asked EPA to issue a rule requiring disclosure of 371 inert ingredients found in pesticide products. EPA developed an alternative strategy designed to reduce the risks posed by hazardous inert ingredients in pesticide products more effectively than by disclosure rulemaking. EPA outlined its strategy in a May 22, 2014, letter to the petitioners, which is available online. Many of the 72 inert ingredients targeted for removal are on the list of 371 inert ingredients identified by the petitioners as hazardous. The 72 chemicals are not currently being used as inert ingredients in any pesticide product. The list of chemicals is available online.
Ingredients that are directly responsible for controlling pests such as insects or weeds are called active ingredients. An inert ingredient is any substance that is intentionally included in a pesticide that is not an active ingredient. Comments are due November 21, 2014. General information on inert ingredients can be found online.

On October 15, 2014, the Office of Pesticide Programs (OPP) announced a voluntary program to document the effectiveness of agricultural pesticide spray application technologies on reducing pesticide spray drift. Under the Drift Reduction Technology (DRT) Program, agricultural equipment manufacturers would conduct (or make arrangements for a testing facility to conduct) studies to determine the percent drift reduction according to a verification protocol. Once completed, the manufacturer would submit the study to the U.S. Environmental Protection Agency (EPA) for review and evaluation. As verified, these reductions could then be quantitatively credited in the environmental risk assessments used to develop the drift reduction measures appearing on the label of the pesticide product. EPA will then review the manufacturers’ studies and, based on these data, it will assign spraying devices a rating on a four-star scale:
* Four stars: Device can reduce spray drift by 90 percent or more.
* Three stars: Device can reduce spray drift by between 75 percent to 89 percent.
* Two stars: Device can reduce spray drift by between 50 percent to 74 percent.
* One star: Device can reduce spray drift by between 25 percent to 49 percent.
* No stars: Device can reduce spray drift by less than 25 percent.
EPA allows pesticide manufacturers to include labeling on their products that contain dual-use instructions, one for farmers using devices that have received stars through the DRT program and another for those using devices that do not have a DRT rating.

On September 30, 2014, the U.S. Environmental Protection Agency (EPA) redesigned the Pesticide Registration Improvement Extension Act of 2012 (PRIA 3) website. The new website is available at www2.epa.gov/pria-fees. The purpose of the redesign is to make PRIA 3 information more easily accessible to stakeholders and the public, regardless of the type of device being used. EPA made no technical or regulatory changes to PRIA 3.

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 August 7, 2014, the U.S. Environmental Protection Agency (EPA) announced that it has consolidated information on soil fumigants and placed it on a new “user-friendly” website. In an e-mail announcing the launch of its new Soil Fumigant Toolbox, EPA noted that the site is intended to reduce exposure to agricultural workers and the public. The website includes information on soil fumigants, buffer zones, and information targeted for communities, certified applicators of soil fumigants, and state and Tribal environmental agencies. EPA’s soil fumigant website is available online.

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.
