On February 1, 2018, the U.S. Environmental Protection Agency (EPA) announced it is publishing new guidance that sets forth a tiered approach intended to help manufacturers and EPA determine when the number of field trials necessary to register seed treatment uses can be reduced.
In its memo and attached Seed-Treatment Focus Group (STFG) Guidance Document dated January 26, 2018, EPA states that its Health Effect Divison (HED) has received “multiple waiver requests for seed-treatment field-trial residue data and has reviewed multiple field-trial datasets that indicated that there was the potential to reduce the number of field trials required to support the registration of seed-treatment uses.” EPA states that to evaluate this hypothesis, the HED Chemistry Science Advisory Council (ChemSAC), in collaboration with the Health Canada Pest Management Regulatory Agency (PMRA), in accordance with the July 11, 2017, Joint Canada/United States Field Trial Requirements “performed a retrospective analysis of all seed-treatment residue data that have been submitted to EPA/PMRA and has developed a tiered approach for determining if current crop-specific field trial data requirements are required to support new seed-treatment uses, or if a reduction in the number of required field trials is appropriate.” EPA’s announcement states that “the analysis showed that the data required to support registration could be substantially reduced and still be protective of human health.”
EPA developed two decision trees detailing the process for determining the residue chemistry field trial data requirements for seed-treatment uses: one for potato seed-piece (PSP) treatments only and another one for all remaining crops. EPA states that this case study demonstrates that application of the guidance set forth in these decision trees can, for both manufacturers and the agency, “potentially save considerable resources in terms of conducting, submitting, and reviewing the studies while still obtaining the data necessary to support seed-treatment pesticide registrations.”
The outlined procedure and memo document will supersede EPA’s previous guidance issued on October 28, 1999, entitled “Classification of Seed Treatments as Food or Nonfood Uses.”
More information is available on EPA’s Determining the Number of Field Trials Required to Register Seed-Treatment Uses webpage.
This announcement of improved review procedures allows EPA to cite both greater coordination across national borders (working with Canada), and reduce unnecessary data requirements. This would fit with the current Administration’s emphasis on reducing regulatory burdens and fostering greater innovation in regulated arenas. It also might be seen as general “good government,” as it updates guidance which is now almost twenty years old. Since seed treatment technology and associated policy issues have both evolved over the years, such a review and revision would seem timely regardless of any larger political directive.

On January 22, 2018, the White House again delayed the effective date of revisions to the Federal Policy for the Protection of Human Subjects, referred to as the Common Rule. Final revisions were published on January 19, 2017. On September 8, 2015, the U.S. Department of Health and Human Services (HHS) and 15 other federal departments and agencies published a Notice of Proposed Rulemaking (NPRM) proposing revisions to each agency’s codification of the Federal Policy for the Protection of Human Subjects, originally promulgated as a Common Rule in 1991. 80 Fed. Reg. 53931. On January 19, 2017, HHS and other federal departments and agencies published a final rule revising the Federal Policy for the Protection of Human Subjects. 82 Fed. Reg. 7149. The revised policy, referred to as the “2018 Requirements,” was scheduled to become effective on January 19, 2018, with a general compliance date of January 19, 2018, with the exception of the revisions to the cooperative research provisions for which the compliance date is January 20, 2020.
After publication of the 2018 Requirements, representatives of industry, including organizations representing recipients of federal human subjects research awards, expressed concern regarding their ability to implement all of the 2018 Requirements by the scheduled general compliance date. Stakeholders requested a delay in the general compliance date of the 2018 Requirements with the exception of certain burden-reducing provisions of the 2018 Requirements, including certain carve-outs from the definition of “research” exemptions, elimination of the continuing review requirements for certain categories of research, and the elimination of the requirement that institutional review boards (IRB) review grant applications. The HHS Secretary’s Advisory Committee on Human Research Protections (SACHRP) also recommended in August 2017 that implementation of the 2018 Requirements should be delayed. The new effective date is July 19, 2018. Comments are due by March 19, 2018.

On August 28, 2017, the U.S. Environmental Protection Agency (EPA) announced the first of three feature and functionality updates to the Pesticide Submission Portal (PSP) expected this year. The portal is a web-based application allowing registrants to submit pesticide application packages to EPA electronically. The PSP application is accessed through EPA’s Central Data Exchange (CDX) Network which requires user registration.
This new PSP, version 1.4, release expands the feature to allow users to submit voluntary data related to specific registration review cases. Users can submit study citations, data matrices (Form 8570-35), cover letters and studies (protocols, study profiles, supplemental study data) using the new "Voluntary Submission" link on the PSP home page. This new release also allows users to resubmit previously submitted 90-day responses. Once a 90-day response or data submission has been successfully transmitted to the Office of Pesticide Programs (OPP), users may now modify responses to data requirements, cite additional studies, upload additional documents, and change how the product registration is supported. EPA states: “This action is another step in a phased approach that will ultimately lead to EPA’s ability to accept all pesticide applications electronically, a move that will help modernize the pesticide registration process, increase operational efficiencies and reduce paper waste.” EPA indicates that in addition to these changes, this update introduces enhancements and bug fixes.
EPA also released the OPP Pesticide Submission Portal (PSP) User Guide Version 1.4 which provides detailed instructions on how to use the PSP application and guidance on how to prepare a package for electronic submission.
Applicants using PSP need not submit multiple electronic copies of any pieces of their applications; EPA states that the requirement to submit multiple copies of data in Pesticide Registration Notice 2011-3 is applicable only to paper submissions. Pesticide registrants who previously submitted information via paper, CD, or DVD may instead use the portal and forego the courier costs of sending to EPA.
More information about the Electronic Submissions of Pesticide Applications is available on EPA’s website.

On August 1, 2017, the U.S. Environmental Protection Agency (EPA) announced the availability of two final test method Standard Operating Procedures (SOP) for evaluating the efficacy of antimicrobial pesticides against two biofilm bacteria, Pseudomonas aeruginosa (P. aeruginosa) and Staphylococcus aureus (S. aureus):
EPA also released regulatory guidance for test criteria and pesticide claims for these products, specifically Guidance for Testing the Efficacy of Antimicrobial Products Against Biofilms on Hard, Non-Porous Surfaces. Drafts of the SOPs and the guidance were initially released in October 2016 for comment. EPA received comments from nine entities and revised the drafts to incorporate suggested changes. EPA posted its response to those comments in Docket EPA-HQ-OPP-2016-0357.
EPA states that the two methods are adapted from ASTM International (ASTM) standard methods. EPA MLB SOP MB-19 is used to generate the P. aeruginosa or S. aureus biofilm on coupons. EPA MLB SOP MB-20, the Single Tube Method, then is used to determine the effectiveness of an antimicrobial product in reducing bacteria in biofilm on the coupons.
Notable aspects of the test criteria and claims guidelines include:
- The mean log density for the test organisms of 8.0 to 9.5 for P. aeruginosa and 7.5 to 9.0 for S. aureus; and
- Product performance criterion of a minimum 6-log reduction.
The guidance lists several examples of claims for efficacy against public health biofilm that EPA states are acceptable.
EPA MLB SOP MB-20 is designed to evaluate the efficacy of antimicrobial products that are water soluble powders or liquid formulations. If a company wishes to test a different type of product formulation, or test different target microorganisms, or make any other proposed modifications, it would be well advised to submit proposed alternatives to EPA for review and approval. EPA specifically cautions that the current methodologies are intended for data development to support claims for products registered for use on hard, non-porous surfaces and are not suitable for use sites associated with water systems.
The EPA’s Office of Pesticide Programs’ (OPP) regulation of biofilms has been the subject of increasingly intense commercial interest for years and the availability of this testing guidance is welcome news. While not all will agree with the approach, the new guidance is a helpful addition to OPP’s testing guidance portfolio.
More information on antimicrobial pesticides is available on our blog under key phrase Antimicrobial Pesticide. More information on the methods and guidance is available on EPA’s website and in Docket No. EPA-HQ-OPP-2016-0357.

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 8, 2016, the U.S. Environmental Protection Agency (EPA) announced its invitation for public input regarding the “Strategic Roadmap: New Approaches to Evaluate the Safety of Chemicals and Medical Products” (Roadmap), the development of which was coordinated by the National Toxicology Program’s (NTP) Interagency Coordinating Committee on the Validation of Alternative Methods (ICCVAM). ICCVAM states that the vision of the Roadmap is to “establish new approaches for evaluating the safety of chemicals and medical products in the United States that will increase confidence in alternative methods and improve their relevance to human health outcomes while maximizing efficiency and maintaining a commitment to replace, reduce, and refine animal use.” ICCVAM’s Roadmap effort was introduced in March 2016. A detailed presentation on the development of the Roadmap is available here.
ICCVAM, a permanent committee of the National Institute of Environmental Health Sciences (NIEHS) under the National Toxicology Program Interagency Center for the Evaluation of Alternative Toxicological Methods (NICEATM), is composed of representatives from 16 U.S. federal regulatory and research agencies that require, use, generate, or disseminate toxicological and safety testing information. As a participating member of ICCVAM, EPA states that its role is to “encourage the development and use of alternatives to animal test methods, ensure that new methods are valid, review test method recommendations, and as appropriate, adopt these alternatives in our own regulatory programs.”
There are also three upcoming public meetings that will provide additional opportunities to comment on topics relevant to this effort:
- ICCVAM Public Forum: May 23, 2017, National Institutes of Health (NIH), Bethesda, Maryland;
- NTP Board of Scientific Counselors meeting: June 29, 2017, NIEHS, Research Triangle Park, North Carolina; and
- Scientific Advisory Committee on Alternative Toxicological Methods meeting: September 18-19, 2017, NIH, Bethesda, Maryland.
As ICCVAM’s commitment to replace, reduce, and refine animal use continues to draw public comment and gain support, there is an increasing need to demonstrate the utility and harmonization of predictive approaches in toxicology testing with the conventional safety evaluation of chemicals and medical products. Bergeson & Campbell, P.C. (B&C®) continues to monitor the development, validation, and implementation of alternative in vitro and in silico test methods, high throughput screening assays, and computational models as they are integrated into global regulatory frameworks.

On January 19, 2017, the U.S. Environmental Protection Agency (EPA), together with a host of other federal agencies, announced revisions via 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. 82 Fed. Reg. 7151. The Federal Register publication states that this final rule is intended to “better protect human subjects involved in research, while facilitating valuable research and reducing burden, delay, and ambiguity for investigators, and “these revisions are an effort to modernize, simplify, and enhance the current system of oversight.” The rule will become effective on January 19, 2018. The compliance date is also January 19, 2018, with some exceptions.
The final rule differs in important ways from the proposed rule issued on September 8, 2015; most significantly, several proposals are not being adopted. Other minor changes have been to improve the rule and for purposes of clarity and accuracy. Some of the changes include:
- It does not adopt the proposal to require that research involving nonidentified biospecimens be subject to the Common Rule, and that consent would need to be obtained in order to conduct such research.
- To the extent some of the proposals relied on standards that had not yet been proposed, the final rule either does not adopt those proposals or includes revisions to eliminate such reliance.
- It does not expand the policy to cover clinical trials that are not federally funded.
- It does not adopt the proposed new concept of ‘‘excluded’’ activities. Generally, activities proposed to be excluded are now either described as not satisfying the definition of what constitutes research under the regulations or are classified as exempt.
- The proposed revisions to the exemption categories have been modified to better align with the longstanding ordering in the final rule. It does not include the proposed requirement that exemption determinations need to be made in specified ways.
- It does not include the proposed standardized privacy safeguards for identifiable private information and identifiable biospecimens.
- It does not adopt the most restrictive proposed criteria for obtaining a waiver of the consent requirements relating to research with identifiable biospecimens.
The final rule makes the following significant changes to the Common Rule:
- Establishes new requirements regarding the information that must be given to prospective research subjects as part of the informed consent process.
- Allows the use of broad consent (i.e., seeking prospective consent to unspecified future research) from a subject for storage, maintenance, and secondary research use of identifiable private information and identifiable biospecimens. Broad consent will be an optional alternative that an investigator may choose instead of, for example, conducting the research on nonidentified information and nonidentified biospecimens, having an institutional review board (IRB) waive the requirement for informed consent, or obtaining consent for a specific study.
- Establishes new exempt categories of research based on their risk profile. Under some of the new categories, exempt research would be required to undergo limited IRB review to ensure that there are adequate privacy safeguards for identifiable private information and identifiable biospecimens.
- Creates a requirement for U.S.-based institutions engaged in cooperative research to use a single IRB for that portion of the research that takes place within the United States, with certain exceptions. This requirement becomes effective three years after publication of the final rule.
- Removes the requirement to conduct continuing review of ongoing research for studies that undergo expedited review and for studies that have completed study interventions and are merely analyzing study data or involve only observational follow up in conjunction with standard clinical care.

On December 29, 2016, the U.S. Environmental Protection Agency (EPA) issued a notice regarding the availability of final test guidelines, OCSPP Series 850 Group A -- Ecological Effects, part of a series of test guidelines established by the Office of Chemical Safety and Pollution Prevention (OCSPP) for use in testing pesticides and chemical substances to develop data for submission to EPA under the Federal Food, Drug and Cosmetic Act (FFDCA), the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA), and the Toxic Substances Control Act (TSCA). The notice states that these test guidelines “serve as a compendium of accepted scientific methodologies and protocols that are intended to provide data to inform regulatory decisions,” and they “provide guidance for conducting the test, and are also used by EPA, the public, and companies that submit data to EPA.” The test guidelines will be accessible through EPA Docket ID Numbers EPA-HQ-OPPT-2009-0150 through EPAHQ-OPPT-2009-0159, and EPA-HQ-OPPT-2009-0576 on www.regulations.gov.
The changes to test guidelines are varied. Some of the changes include:
- Simple cosmetic changes, e.g., presentation of test conditions, test validity criteria, and equations for calculating response measurements;
- Housekeeping changes, e.g., the addition of final versions of draft guidelines that had not been prepared in final yet;
- The addition of a limit test option to several acute invertebrate toxicity tests;
- Changes from “cut off” dosages in existing guidelines to limit concentrations and a change in the limit concentration for industrial chemicals from “1,000 milligrams/liter (mg/L)” to “100 mg/L” for acute toxicity tests and “10 mg/L” for chronic tests; and
- Changes to terminology, e.g., to clarify 10-day versus acute exposures for sediment-dwelling invertebrate toxicity tests and saltwater versus marine conditions.
The addition of a limit test option aligns well with the new TSCA mandate to reduce vertebrate testing as a matter of federal policy. EPA notes that certain guidelines were not issued in final, but remain available for reference as draft guidelines. In that certain ecological effects guidelines relate to guidelines already developed for the Endocrine Disruptor Screening Program (EDSP), EPA notes that it will consider test design elements from the relevant EDSP guidelines in the development of OSCPP 850 series guidelines.

On December 20, 2016, the U.S. Environmental Protection Agency (EPA) announced the start of a pilot program to evaluate the usefulness and acceptability of a mathematical tool (the GHS Mixtures Equation), which is used in the Globally Harmonized System of Classification and Labeling of Chemicals (GHS). EPA states that the goal of the pilot program is to “evaluate the utility and acceptability of the GHS Mixtures Equation as an alternative to animal oral and inhalation toxicity studies for pesticide formulations.”
For this pilot program, EPA is requesting submission of acute oral and acute inhalation toxicity study data paired with mathematical calculations (GHS Mixtures Equation data) to support the evaluation of pesticide product formulations; instruction for doing so are available on the GHS Equation Pilot Program webpage, and Guidance on the GHS Mixtures Equation is available in the Guidance on the Application of the CLP (Classification, Labeling and Packaging) Criteria.
The program is an interesting approach considering the conceptual differences of risk assessment and hazard determination that exist at the core of EPA risk approaches and GHS fundamentals. Also, the definition of the EPA Categories compared to GHS has been problematic for hazard communication applications.
Mixture calculation tools rely on the availability of data for all components and would only be applicable if the data for each were generated using the same species under similar exposure conditions.
This pilot program is being developed under EPA’s initiative to develop non-animal alternatives for acute toxicity testing, as well as EPA’s Office of Pesticide Programs’ Strategic Vision for Adopting 21st Century Science Methodologies. More information on these initiatives can be found on our Pesticide Law and Policy blog under key phrase “toxicity testing.”

On September 19, 2016, the U.S. Environmental Protection Agency’s (EPA) Office of Inspector General (OIG) issued a report, EPA Needs a Risk-Based Strategy to Assure Continued Effectiveness of Hospital-Level Disinfectants, the result of OIG’s review of EPA’s Antimicrobial Testing Program (ATP) to “determine whether the program ensures the efficacy of EPA-registered hospital sterilants, disinfectants, and tuberculocides (“hospital-level disinfectants”); and to evaluate options for improving the ATP.” OIG found that the ATP “does not assure that hospital-level disinfectant products continue to be effective after they are registered,” specifically that:
- Once the EPA tests a product and it passes, it is listed as Agency Confirmed Efficacy on the agency’s website and is typically not tested again; the long-term efficacy of the product cannot be assured.
- EPA relies on manufacturers to voluntarily submit product samples for testing. In the last three years, out of the approximately 300 registered hospital disinfectant products that have not been tested, manufacturers submitted only 12 samples to EPA for ATP efficacy testing.
Importantly, however, OIG concludes: “Although the program as currently designed and conducted does not assure that most hospital disinfectant products continue to be effective, at this point it is redundant and unnecessary to make adjustments, since the EPA is concurrently having the products re-registered.”
OIG makes two major recommendations:
- EPA should suspend administering the current Antimicrobial Testing Program until completion of the one-time re-registration process.
- EPA should develop a risk-based antimicrobial testing strategy to assure the effectiveness of public health pesticides used in hospital settings once products are in the marketplace. At a minimum, OIG states, the strategy should:
- Include a framework for periodic testing to assure products continue to be effective after registration.
- Define a program scope that is flexible and responsive to current and relevant public health risks.
- Identify risk factors for selecting products to test.
- Identify the method to be used for obtaining samples for testing.
- Designate a date to commence risk-based post-registration testing.
In its response, EPA agreed with OIG’s recommendations, and stated it will develop a plan to coordinate and implement the discontinuation of the present-day program, with the closure of the ATP program to take place by November 2017. EPA also stated that by December 2018 it plans to develop a risk-based strategy to assure the effectiveness of public health pesticides used in hospital settings once products are in the marketplace.
Registrants of the affected products should monitor closely the development of EPA’s plans both to discontinue the program and to establish this new risk-based strategy for assuring product efficacy.
