On May 31, 2017, the U.S. Environmental Protection Agency (EPA) announced the release of its Food Contact Sanitizing Solutions Model (FCSSM), a pesticide risk assessment model that has been developed to “estimate indirect dietary exposure to components of sanitizing solutions used in commercial settings.”  EPA states that “the model offers guidance for estimating exposure where there may be inadvertent transfer of residue to edible items prepared or transported on surfaces treated with these pesticides.”  The model consists of spreadsheets that automatically calculate dietary exposure and risk estimates based on data entered by the user.  The model estimates exposures to antimicrobial active ingredients listed under 40 C.F.R. § 180.940(b) and 40 C.F.R. § 180.940(c), where 940(b) includes uses in dairy processing equipment and food processing equipment and utensils, while 940(c) excludes dairy processing equipment.  FCSSM does not apply to active ingredients listed under 40 C.F.R. § 180.940(a), which are used on food contact surfaces in public eating places as well as dairy and food processing equipment.  For this case, EPA’s established methodology remains in place.  Compared to the simple calculation method used previously for these use scenarios, the major new feature of the FCSSM is the separate calculations of both acute and chronic dietary exposures for the general U.S. population and eight subpopulations.  EPA also released a user guide that provides background information on the model and familiarizes users with the inputs required to run the model.

More information about the FCSSM as well as other models used for pesticide risk assessments is available on EPA’s website

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 May, 24, 2017, the California Department of Pesticide Regulation (DPR) issued guidance regarding its Notice 2015-13 to applicants registering pesticide impregnated materials bearing pesticide claims to be sold and distributed into or within California, per Notice 2015-13, issued December 11, 2015.  Each retailer (or authorized representative) of an affected product must submit an Application for Pesticide Registration (DPR-REG-030) to DPR by July 1, 2017

The guidance includes information on the registration requirements, as well as:

More details on the requirements are available in our blog items California Issues Notice Requiring Registration for Products Made From Pesticide Impregnated Materials and Bearing Pesticide Claims and California DPR Extends Filing Date to Register Pesticide Impregnated Products.


 

By Lisa M. Campbell and Lisa R. Burchi

On February 22, 2017, the California Department of Pesticide Regulation (DPR) announced it was extending the filing date for applications to register products made from pesticide impregnated materials bearing pesticide claims from March 1, 2017, to July 1, 2017.  Specifically, each retailer (or authorized representative) of an affected product must submit an Application for Pesticide Registration (DPR-REG-030) to DPR by July 1, 2017.  DPR’s California Notice 2015-13 issued on December 11, 2015, informed pesticide product registrants and stakeholders of DPR’s intention to register products made with pesticide impregnated materials and bearing pesticide claims. 

The February 22 notice also states the following in terms of the requirements:

  • Each company with products made from pesticide impregnated material and sold under their own company name into or within California is required to register the product(s) as a pesticide;
  • The product must bear a federally approved pesticide label; DPR will assign a separate California-only registration number for purposes of tracking sales and use of the products in California;
  • Each company will need to obtain at least one registration for each use category of product sold (e.g., the apparel use category includes wearable items such as jackets, shirts, hats, socks, pants, and shorts; the non-apparel use category includes non-wearable items such as bedding, tents, seat covers, chopping blocks, shower curtains, and mouse pads); and
  • If items are impregnated with different pesticides or different percentages of the same pesticide, separate registrations will be required.

The requirements set forth in this notice do not apply to products that satisfy the requirements to be a treated article, including the requirement that any claims be related to protection of the article/substance itself.  The notice applies instead to those pesticide impregnated materials that include pesticidal claims that are not limited to protection of the material.  More information on the December 2015 notice is available in our blog item California Issues Notice Requiring Registration for Products Made From Pesticide Impregnated Materials and Bearing Pesticide Claims.

On January 12, 2017, the U.S. Environmental Protection Agency (EPA) released its Policy to Mitigate the Acute Risk to Bees from Pesticide Products (Mitigation Policy) which describes methods for addressing acute risks to bees from pesticides.  EPA states that this Mitigation Policy is “more flexible and practical than the proposed policy” that was issued on May 29, 2015, and it has “made modifications to its approach with the goal of better targeting compounds that pose an acute risk, and with the goal of reducing potential impact of this effort on growers.”  EPA states that it will use its Tier 1 acute risk assessment to, in part, determine the products that trigger concerns about pollinator risk that the label restrictions are intended to address.  EPA will begin implementing this Policy in 2017 by sending letters to registrants describing steps that must be taken to incorporate the new labeling.  More information on the Mitigation Policy, including its supporting documents, and EPA’s response to comments submitted on the proposed policy, is available on www.regulations.gov under Docket ID EPA-HQ-OPP-2014-0818.

Also on January 12, 2017, EPA published preliminary pollinator-only risk assessments for the neonicotinoid insecticides clothianidin, thiamethoxam, and dinotefuran, and an update to its preliminary risk assessment for imidacloprid, published in January 2016.  EPA states that the preliminary assessments for clothianidin, thiamethoxam, and dinotefuran are similar to the preliminary pollinator assessment for imidacloprid, in that they showed that “most approved uses do not pose significant risks to bee colonies,” but “spray applications to a few crops, such as cucumbers, berries, and cotton, may pose risks to bees that come in direct contact with residue.”  As for the updated imidacloprid assessment, EPA states that is looked at potential risks to aquatic species, and identified some risks for aquatic insects.  Interested parties will have 60 days to comment on the preliminary risk assessments after notice is published in the Federal Register.  In terms of comments, EPA states that it is especially interested in getting input from stakeholders “on the new method for assessing potential exposure and risk through pollen and nectar.”  Links to risk assessment dockets for each individual insecticide are available on EPA’s website under Schedule for Review of Neonicotinoid Pesticides.  EPA states it is hopes to release the final neonicotinoid risk assessments by mid-2018.

Commentary

The revised Mitigation Policy has been long in coming since it was first released over eighteen months ago.  The delay in revising its approach reflects the complexity of the comments submitted, and EPA’s deliberateness in more finely crafting its policies, given the passage of time and other considerations.  This revised policy contains more flexibility and explicit discussion of the need for exceptions to blanket requirements in response to some of the comments received on the earlier proposal.  There remains significant public and regulator concern about the possible impacts on pollinators from pesticide use, however, there is currently less of a manic tone to EPA’s statements and actions.

For example, when discussing how EPA will approach changing the labels of the affected universe of pesticide products, there is a much less onerous tone and no specific deadlines for registrants to submit revised labels “or else.”  (The 2013 directives to registrants included demands for thousands of revised labels to be submitted within six weeks “or else” -- EPA would take “appropriate action” under FIFRA.)  EPA reminds us all that it retains authority to impose these new requirements broadly, a statement that will strike some as regulatory overreach, but the tone and approach is more in line with past EPA “guidance” about how it will approach a new or revised regulatory concern.   

Similar to what EPA previously concluded about imidacloprid, where that assessment concluded that the most controversial use -- corn seed treatments -- did not indicate a risk concern, EPA did include in its summary about the other three neonicotinoid pesticides that:

  • The assessments for clothianidin, thiamethoxam, and dinotefuran, similar to the preliminary pollinator assessment for imidacloprid showed:  most approved uses do not pose significant risks to bee colonies.  However, spray applications to a few crops, such as cucumbers, berries, and cotton, may pose risks to bees that come in direct contact with residue.

This might unfairly be summarized as:  after years of regulatory analysis EPA has concluded that if insecticides come into direct contact with insects, there is likely to be a risk to the exposed insect. 

This conclusion would be too simplistic since EPA and other regulatory bodies have expressed concern about what unintended exposures to insecticides might cause, and more generally the possibility of colony level impacts on honeybee and other pollinator populations from pesticide use.  Some critics will continue to insist that EPA broaden its regulatory approach to more than just pesticides used for crops under contracted pollinator services.  The broader issue of pesticide drift and possible impacts on non-target species will continue to be a concern for all pesticides.

Perhaps the more deliberate consideration of needed data generation and assessment that seems to be the current approach will allow both more refined regulatory controls if needed, and a reduction in the sometimes hot rhetoric which has accompanied the pollinator issues.

Lastly, although this revised Mitigation Policy and the three new preliminary assessments are not unexpected next steps as part of the ongoing registration review program for pesticides, given their very late release -- less than ten days before the arrival of a new Administration -- some might question whether this is part of the “midnight regulations” pushing the political agenda of the outgoing Administration.  The new leadership may revise what has been released, and may come to different conclusions about any needed restrictions.  That said, the issue of whether certain pesticides are having a dangerous impact on honeybee populations will continue to be a concern for regulators both in the U.S. and globally.

The U.S. Environmental Protection Agency (EPA) has recently announced the availability of two proposed test methods and associated testing guidance for evaluating antimicrobial pesticides against two biofilm bacteria, Pseudomonas aeruginosa and Staphylococcus aureus, for comments.  EPA states that registrants of antimicrobial products with public health claims are “required to submit efficacy data to EPA in support of the product’s registration” under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA).  EPA is soliciting comments on the clarity of the standard operating procedures and the regulatory guidance.  The two test methods are:

The Draft Guidance to Assess the Efficacy of Antimicrobial Pesticide Products Intended to Control Public Health Biofilms on Hard, Non-Porous Surfaces describes biofilms and their public health significance; the two test procedures for developing efficacy data supporting biofilm claims; products that may be eligible for biofilm claims; test criteria; data submission procedures for efficacy data; and labeling guidance.

The draft guidance states that the term biofilm “is reserved for claims against biofilm that contain specific bacteria that are directly or indirectly infectious or pathogenic to humans,” and “biofilm claims are considered to be public health claims for which the agency must review and approve appropriate efficacy data.”  EPA states: “Examples of use sites that may be supported by the biofilm test methodologies herein, and found acceptable, include restrooms, shower stalls, sink basins or drains (excluding the drain pipe) and nearby hard, non-porous surfaces of walls, countertops, and instrument trays in patient care areas of hospitals.  In contrast, claims against non-public health slimicides must also be supported by appropriate efficacy data, however, submission of the data is only required when requested by the EPA.” 

The Draft Guidance also sets forth examples of acceptable label claims against public health biofilms and acceptable non-public health claims.  The examples of acceptable label claims against public health biofilms are:

  1. Kills 99.9999% of bacteria* in biofilm on a hard, non-porous surface;
  2. Kills a minimum of 99.9999% of bacteria* in biofilm;
  3. Reduces at least 99.9999% of bacteria* growing in biofilm;
  4. Formulated to kill 99.9999% of bacteria* in biofilm;
  5. Other related claims:
  • Kills biofilm bacteria*; and
  • Penetrates biofilm, killing the bacteria* living there.

*[List of bacteria “tested as a biofilm”; at a minimum, Pseudomonas aeruginosa and Staphylococcus aureus].

Examples of acceptable non-public health claims supported by appropriate efficacy data include:

  • Slimicide;
  • Cleans away microorganism slime/grunge;
  • Maintains control of slime; and
  • Controls slime-forming microorganisms.

Comments will be accepted until December 5, 2016.

The California Department of Pesticide Regulation (DPR) recently proposed a regulation that it states is intended to “(1) provide minimum statewide standards for all agricultural pesticide applications near public K-12 schools and child day care facilities; (2) provide an extra margin of safety in case of unintended drift or when other problems with applications occur (e.g., equipment failure causes an unintended release of pesticide, or an abrupt change in weather conditions); (3) increase communication between growers and schools/child day care facilities; and (4) provide information to assist schools and child day care facilities in preparing for and responding to pesticide emergencies.”

This proposal has been long anticipated, is far reaching, and of significant concern to many growers and registrants. 

In its Initial Statement of Reasons, DPR summarizes the proposed regulations, stating that they will: “require growers to notify public K-12 schools, child day care facilities (except family day care homes), and county agricultural commissioners when certain pesticide applications made for the production of an agricultural commodity near a schoolsite are planned in the coming year and also a few days prior to the applications.”  The proposed regulation also would prohibit at certain times certain pesticide applications near these schoolsites.  Specifically, the regulation is proposed to do the following:

  • Prohibit many pesticide applications for the production of an “agricultural commodity” within a quarter mile of schoolsites from Monday through Friday between 6:00 a.m. and 6:00 p.m.  “Schoolsites” are defined by Education Code section 17609(f) as: “‘any facility used as a child day care facility, as defined in Section 1596.750 of the Health and Safety Code, or for kindergarten, elementary, or secondary school purposes. The term includes the buildings or structures, playgrounds, athletic fields, vehicles, or any other area of property visited or used by pupils.”  ‘Schoolsite’ does not include any postsecondary educational facility attended by secondary pupils or private kindergarten, elementary, or secondary school facilities.”   DPR also proposed to exclude from the definition of schoolsite any family day care homes “because, unlike other schoolsites, the locations of these facilities are not publically available.”  DPR states it considered other distances but proposed the one-quarter mile radius based on several factors, including but not limited the fact that this restriction is similar to the restrictions on fumigant labels that prohibit closer applications around schools and other difficult to evacuate sites and based on an analysis of pesticide illnesses due to drift from agricultural applications. The proposed prohibition would apply to applications by aircraft, sprinkler chemigation equipment, air-blast sprayers, and fumigant applications. In addition, dust and/or powder pesticide applications would also be prohibited during this time unless applied as a dust or powder using field soil injection equipment.
  • Require California growers and pest control contractors to notify public K-12 schools and child day-care facilities and county agricultural commissioners (CAC) when certain pesticide applications are made within a quarter mile of these schools and facilities.

Under the proposed regulation, California growers would be required to provide two types of notifications to a school or child day-care facility:

An annual notification that lists all the pesticides expected to be used during the upcoming year. This must be provided to the school or child day care facility administrator by April 30 each year.  The notice must include, among other things:

  • The name of pesticide products (and the main active ingredient) to be used;

  • A map showing the location of the field to be treated;

  • Contact information for the grower/operator and the County Agricultural Commissioner; and

  • The web address for the National Pesticide Information Center where additional sources of information or facts on pesticides may be obtained.

An application-specific notification which must be provided to the school or child day-care facility 48 hours before each application is made.  This begins January 1, 2018, and must include, among other things:

  • Name of pesticide products (and the main active ingredient) to be used;
  • Specific location of the application and the number of acres to be treated; and
  • Earliest date and time of the application.

Comments on the proposed regulation are due by November 17, 2016.  DPR states that a final regulation is expected to become effective in September 2017.   
 
Many have concerns with the proposed regulation, which DPR has been discussing publicly for some time.  These concerns include what many believe are significant economic impacts to growers and others that they believe may not have been adequately considered and are not necessary for appropriate use of registered pesticides.  Registrants and others should review the proposal carefully.

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.

On March 25, 2016, the U.S. Environmental Protection Agency’s (EPA) Office of Inspector General (OIG) sent a memorandum to Jim Jones, Assistant Administrator, Office of Chemical Safety and Pollution Prevention (OCSPP), announcing that it plans to begin preliminary research to assess EPA’s management and oversight of resistance issues related to herbicide tolerant genetically engineered (GE) crops.  OIG states that its review will include the Office of Pesticide Programs (OPP), as well as other applicable headquarters and regional offices.  OIG’s objectives are to determine:

  1. What processes and practices, including alternatives, EPA has provided to delay herbicide resistance;
  2. What steps EPA has taken to determine and validate the accurate risk to human health and the environment for approved pesticides to be used to combat herbicide resistant weeds; and
  3. Whether EPA independently collects and assesses data on, and mitigates actual occurrences of, herbicide resistance in the field.

OIG states that the anticipated benefit of the project “is a greater understanding of herbicide resistance[,] which will lead to an enhancement of EPA’s herbicide resistance management and oversight.”

Commentary

Pesticide resistance is not a new issue and is one that EPA has affirmatively addressed when granting registrations for new products, GE or not, for some time.  In fact, that newer chemistries often have a more niche mode of action to reduce potential toxicity concerns has led some observers to speculate that greater resistance is one potential trade-off for the development of less toxic materials.

This “investigation” may appear to some to be a response to concerns raised by critics of GE crops generally and to a recent EPA decision to approve Enlist Duo herbicide, a new formulation of 2,4,D- and glyphosate designed to address the problem of weed resistance to glyphosate-tolerant crops.  Glyphosate tolerant crops were first approved some years ago, and their use was so broadly and readily adopted that issues have arisen with regard to potential resistance to some weed species.  EPA is currently expected to approve another GE strain, Dicamba-tolerant crops, to control glyphosate tolerant weeds.

To critics of GE crops, using more herbicides to control problems caused by what they claim is overuse of another herbicide is evidence of a troubling “pesticide treadmill,” which they believe should not have been allowed to occur in the first place.  Rebutting this criticism, others assert that resistance is a problem for all pesticides, not only genetically modified ones, and that with sufficient controls, resistance can be delayed, if not avoided.  Registrants point out that it is very much in their self-interest to take steps to avoid resistance to their products -- once that occurs, the market viability of the product is significantly reduced.

On February 2, 2016, the Executive Board of the North American Free Trade Agreement (NAFTA) Technical Working Group on Pesticides (TWG) released details of its proposed strategic framework the next five years.  The environmental regulatory authorities in the U.S., Canada, and Mexico comprise the TWG and developed the strategy.  They are the U.S. Environmental Protection Agency (EPA), Health Canada’s Pest Management Regulatory Agency (PMRA), and Mexico’s Secretaría de Agricultura, Ganadería, Desarrollo Rural, Pesca y Alimentación (SAGARPA) and its Secretaría de Medio Ambiente y Recursos Naturales (SEMARNAT) .

The message from the Executive Board states that the main goal is to “align the North American registration systems for pesticides and products treated with pesticides and make work-sharing a way of doing business.”  There are three strategic objectives listed in the message, as described below.  Information regarding some of these strategic objectives is discussed in our blog.

Objective 1: Identify trade barriers and approaches to promote equal access and simultaneous introduction for pest management tools, which includes:

  • MRL Alignment:  This objective includes the alignment of maximum residue limits (MRL) to encourage registrants to consider potential export markets of agricultural commodities intended for treatment with proposed new pesticides or new uses as a way to reduce the number of use expansion submissions and reduce potential trade barriers.
  • Expansion, Development and Harmonization of Crop Groups with Specified Representative Crops for Field Crop Residues Studies:  The TWG plans to continue ongoing work, through the International Crop Grouping Consulting Committee (ICGCC) for harmonizing crops, on the process for developing new/additional crop groups and to revise the existing guidance document as new scientific information becomes available.

Objective 2: Encourage cooperation on joint reviews of new pesticides and uses, and the reevaluation/re-registration review of pesticides to increase efficiency and quality of decision making, which includes:

  • Increasing Simultaneous Registration of Biopesticides:  The TWG will seek opportunities with biopesticide manufacturers for their simultaneous submission of registration applications to NAFTA countries to provide opportunities for joint review.
  • Minor Use Joint Reviews:  The TWG will continue the focus on pesticide registration for minor uses, and will work with the minor crop grower communities, the U.S. IR-4 program, and the Canadian Pest Management Centre program to: identify pest control gaps; follow the established minor use joint review procedures to enable joint submissions of registration applications in U.S. and Canada; and make simultaneous regulatory decisions in both countries within a 10-month timeframe.
  • Coordination of Registration Review and Re-evaluation:  The TWG will continue to identify opportunities for countries to work-share on pesticides; work shares that are currently ongoing include the glyphosate and neonicotinoid pesticides.

Objective 3:  Work cooperatively on priority science and regulatory issues and practices including data requirements, science approaches and policies for data interpretation, and risk assessment and communications of regulatory decisions, which includes:

  • Pollinator Protection:  The TWG will share information on policies, risk assessments, initiatives, and actions to improve the countries’ protection of pollinators, and EPA and PMRA will provide training to SAGARPA and SEMARNAT on the process for conducting pollinator risk assessments.
  • Alignment of Data Requirements/Science Policies:  The TWG will facilitate a common approach and efficiencies in joint reviews and worksharing among the EPA, PMRA, and Mexico; all countries will continue to consider the alignment of data requirements and science policies. This will include developing and completing guidance for the review and interpretation of specific data and guidance related to risk assessment methodologies (e.g., cumulative exposure) and novel technologies such as RNAi (Ribonucleic acid Interference).
  • Integrated Approaches to Testing and Assessment (IATA):  EPA and PMRA will continue to work on initiatives related to Chemical Testing in the 21st Century, e.g., a bilateral effort by EPA and PMRA to develop an OECD Guidance Document that builds upon the existing EPA and PMRA guidelines on waiving/bridging acute toxicity studies, and a continuation of their joint efforts to work with stakeholders on alternative approaches for the acute toxicity studies.

The objectives and specific focus areas are ambitious.  To achieve some of these objectives will require addressing some controversial issues, for example, the confidential treatment of data that underlie these programs (e.g., MRLs, residue studies, biopesticide registrations).

More information on the strategy is available on Health Canada’s website.
