On October 5, 2017, the U.S. Environmental Protection Agency (EPA) issued a notice of extension of the comment period for the draft guidance Pesticide Registration Notice (PR Notice) 2017-XX: Notifications, Non-notifications and Minor Formulation Amendment issued on September 6, 2017.  Comments now must be received by EPA on or before December 5, 2017.  The notice states that it will “allow stakeholders additional time to submit comments on the proposed guidance.”  Eleven comments were filed in the docket, most of which expressed significant concern with changes EPA is proposing, in addition to requesting an extension to the previous deadline which was set to end on October 6, 2017.

EPA states that PR Notice 2017-XX will update and clarify “the scope of changes accepted by notification, non-notification and minor formulation amendments for all pesticide products, and supersedes both PR Notices 95-2 and 98-10 in their entirety.”  A full summary of the changes in the draft guidance is available in our blog item "EPA Releases Draft Guidance for Pesticide Registrants on Notifications, Non-notifications, and Minor Formulation Amendments."

Some of the more substantive comments noted the following issues:

  • Several commenters stated objections to the provisions in the draft PR Notice that would eliminate the ability of registrants of formulated products to use notification to add or change sources of either registered technical active ingredients or inert ingredients.  Concerns expressed with this proposed change included the effect it would have on the ability of registrants to respond quickly to market changes and conditions, including the availability and price of technical and inert ingredients needed for formulations.
  • One commenter had concerns with regard to the proposed changes to the inert ingredient disclosure statement, as EPA is “considering whether the notification method or the non-notification method is an appropriate avenue for industry requested inert disclosure based upon third-party vendor requirements.”  The commenter stated that it “believes there is an approach that satisfies third-party vendors while minimizing the burden on the Agency’s resources,” and “a significant delay to this issue could have third-party vendor impacts.” 
  • Commenters also expressed disappointment with EPA’s notification delivery, stating that EPA “provided very little notice to Stakeholders of this major change in its policies regarding notification” and “as a result, many potentially affected registrants may overlook this change and fail to file comments on it.”

On September 22, 2017, the U.S. Environmental Protection Agency (EPA) issued a notice in the Federal Register (82 Fed. Reg. 44406) announcing the availability of two final Pesticide Registration Notices (PRN):

  1. PRN 2017-1:  Guidance for Pesticide Registrants on Pesticide Resistance Management Labeling, which updates PRN 2001-5 and provides guidance for registrants to follow when developing resistance management information to include on their pesticide labels.  It addresses “end-use herbicide, fungicide/bactericide, or insecticide/acaricide products that are intended mainly for agricultural and certain non-crop land areas under commercial or government-sponsored pest management,” and applies in particular to “all field use agricultural pesticide products, as well as pesticides which are labeled for greenhouse production, sod farms, ornamental crops, aquatic vegetation, rights-of way, and pest management along roadways.”
  2. PRN 2017-2:  Guidance for Herbicide Resistance Management Labeling, Education, Training, and Stewardship, which “communicates the agency's approach to address herbicide-resistant weeds.”  It is “germane to end-use herbicide products used in agriculture, including commercial turf and sod farms, ornamental production in the open.”  It also applies to “non-agricultural use sites such as golf courses, aquatic vegetation, rights-of-way and vegetation management along roadways.”

These final PRNs reflect consideration of public comments submitted on the draft PRNs.  Also available in the dockets are EPA’s responses to comments on the draft PRNs:  Response to Comments on PRN 2017-1; and Response to Comments on PRN 2017-2.  EPA states that “PRNs are issued by the Office of Pesticide Programs (OPP) to inform pesticide registrants and other interested persons about important policies, procedures, and registration-related decisions, and to provide guidance to pesticide registrants and OPP personnel.”

On September 6, 2017, the U.S. Environmental Protection Agency (EPA) published a notice in the Federal Register announcing the availability of and seeking public comment on draft guidance, Pesticide Registration Notice (PR Notice) 2017-XX: Notifications, Non-notifications and Minor Formulation Amendments.  EPA states it is issuing this notice to “align the notification program with the requirements of the Food Quality Protection Act (FQPA) and [the Pesticide Registration Improvement Act (PRIA)] and to clarify the processes for accepting minor, low risk registration amendments to be accomplished through notification, non-notification or as accelerated amendments.”  EPA is requesting comments, and specifically information on projected cost implications of this draft updated guidance.

PR Notices are issued by the Office of Pesticide Programs (OPP).  EPA states that PR Notice 2017-XX will update and clarify “the scope of changes accepted by notification, non-notification and minor formulation amendments for all pesticide products, and supersedes both PR Notices 95-2 and 98-10 in their entirety.”  The PR Notice lists the changes from PRN 98-10 in a table.  Those changes include:

In addition to the changes listed on the table, modifications to PR Notice 98-10 consist of the following:

Notifications

  • F. Product Composition:  (1) Pesticide Category -- Under PR Notice 98-10, the pesticide categories "disinfectant" and "sanitizer" were two pesticide categories that were allowed to be added to a label by notification.  Under the proposed PR Notice, "disinfectant" and "sanitizer" were removed.
     
  • F. Product Composition: (2) Odor -- Under PR Notice 98-10, the terms "fragrance free" and "unscented" were allowed to be added to a label by a notification provided that the product is odorless or nearly odorless and contains odor-masking ingredient such as a perfume.  Under the proposed PR Notice, these terms were removed. 

Minor Formulation Amendments

  • A. Minor Formulation Amendments:  (1) Addition, deletion or substitution of one or more colorants in a formulation -- Under PR Notice 98-10, if a product was intended for a use as a seed treatment or rodenticide, it would not be eligible for an accelerated review; that restriction was deleted from the proposed PR Notice.
     
  • A. Minor Formulation Amendments:  (2) Addition, deletion or substitution of one or more inert ingredients (other than colorants and fragrances) in a formulation -- Under the proposed PR Notice, if a product is a dog/cat pet spot-on product or if an inert is a bittering agent or a safener, the product would not be eligible for an accelerated review. 
     
  • A. Minor Formulation Amendments:  (3) Addition, deletion or substitution of one or more fragrances in a formulation -- Under the proposed PR Notice, fragrances will be eligible for an accelerated review if all fragrance component ingredients are included on the Fragrance Ingredient List; individual fragrance component ingredients that exceed 0.1 percent (by weight) of the total pesticide product composition have existing approval for non-food use as an inert ingredient; and new/modified fragrances for antimicrobial products making public health claims are within the certified limits established for fragrances already approved for the product. 
     
  • Under the proposed PR Notice, products that are not eligible for accelerated review under minor formulation amendments are:
    • Pet spot-on products;
    • Rodenticides;
    • Change to an active ingredient source; 
    • Change to nominal concentration of the active ingredient; or
    • Addition of new or additional Confidential Statements of Formula (CSF).

 

EPA Procedures to Review Notifications

Under the proposed PR Notice, EPA outlines changes to the policy for processing notifications by the Registration Division (RD) and the Biopesticides and Pollution Prevention Division (BPPD), but procedures to process notifications by the Antimicrobials Division remain the same. 

One item to note under the proposed notification process for RD and BPPD is that a registrant may distribute or sell a product modified by notification once EPA receives the notification but, if EPA determines that a product has been modified through notification inappropriately, EPA may initiate regulatory and/or enforcement action without first providing the registrant with an opportunity to submit an application to amend the registration.

Registrants Submitting Minor Formulation Amendments

Under the proposed PR Notice, EPA requires that registrants submit with their application for registration a cover letter listing names and dates of all EPA accepted CSFs.  EPA will consider any CSFs not listed in the cover letter as superseded/no longer valid.

Comments on this PR notice are due October 6, 2017, and can be submitted online under Docket ID EPA-HQ-OPP-2016-0671.

Commentary

Registrants should review the draft PR Notice carefully, as it includes important changes.  For example, the consequence for submitting a minor formulation amendment and neglecting to include a list of all current CSFs is severe.  As another example, EPA signals in its proposal that proceeding to market with a product revised through the notification process may be risky if the submitter has erred in its judgment regarding what is eligible for a notification.  Should the PR Notice be issued without change to this provision, submitters may wish to give close consideration to waiting until it has EPA’s written confirmation that a notification has been accepted before introducing the revised product to market.  Comments on issues of concern should be considered.

The U.S. Environmental Protection Agency (EPA) today released a pre-publication version of a Federal Register notice to be issued on August 16, 2016, extending the deadline to submit comments on draft Pesticide Registration Notice (PRN) 2016-X from August 15, 2016, to September 14, 2016.  A discussion of draft PRN 2016-X, which proposes to update Section 5 of PRN 97-2, and to clarify and update criteria by which EPA classifies crops as “minor use,” is discussed in our blog item EPA Solicits Comments on Updated Method for Establishing Economic Minor Use

 

In the notice extending the comment period, EPA noted that the current comment period is “one of the busiest times of year for pest control experts” and provides an extension that “will allow them extra time to complete their review and comment on the PR Notice.” 

There is one comment that already has been submitted by the U.S. Department of Agriculture (USDA), which EPA stated it consulted prior to releasing the draft PRN 2016-X.  In its comments, USDA states:

  • Regarding acreage cutoffs, USDA supports EPA’s use of acreage estimates from the USDA Agricultural Census, as it is the “most reliable and comprehensive public source for such information in the country.”
  • Regarding EPA’s proposal to apply a seven percent discount rate, USDA recommends that EPA be “open to using supplemental information in determining whether or not an alternative discount rate should be considered.” 
  • Regarding EPA’s proposal that all cases be evaluated using values for costs that range from 60 to 85 percent of gross revenue, USDA requests that EPA provide its rationale as to why this range was chosen.  USDA states: “Although USDA understands that EPA is attempting to reveal the ratio of gross revenue to cost associated with the minor use rather than across an entire company, one could assume that a rational company would not pursue registering a minor use if the ratio of costs to gross revenue was exceedingly higher than the average standard ratio for the company.  Qualitative information, as suggested by EPA, could then be used to further refine the estimate for this ratio.”
  • Regarding EPA’s proposal to use study cost estimates provided by independent laboratories, USDA notes there are instances where data can be significantly more expensive than what would be expected generally and, thus, recommends that EPA “be open to additional, verifiable data a registrant wishes to submit that may indicate that its cost of data generation differs from EPA's standard estimates.”  USDA also suggests that EPA “consider making the cost estimates it is using for individual tests available publically to aid registrants in determining whether or not they need to submit alternative incurred costs for studies they have conducted.”
