California DPR Issues Guidance Intended to Align with EPA’s Secondary Container Labeling for Pesticides

On Friday, November 3, 2017, the California Department of Pesticide Regulation (DPR) issued guidance (California Notice 2017-13) that DPR indicates is intended to align DPR policy with the U.S. Environmental Protection Agency’s (EPA) guidance on secondary container labeling for pesticides.  DPR’s guidance states that secondary containers are used by the pesticide industry as part of the process of applying pesticides and “cannot be sold or distributed.”  The guidance further notes that secondary containers are “most commonly used in institutional settings for concentrated antimicrobials that are diluted prior to use or to hold pesticides filled from a larger container to be used and stored prior to application.” 

Registrants may elect to provide users with labels for secondary containers.  DPR’s new guidance states:  “Secondary container labels are not required to be submitted to U.S. EPA or DPR.”  Under the new DPR policy, however, effective immediately, if a registrant submits a secondary container label to DPR, “it must bear the same signal word as the concentrate label or no signal word.”  DPR states that it will accept a secondary container label with a lesser signal word, precautionary statements, and alternate directions for use for the diluted product only if acute toxicity data are submitted or are currently on file to support these lesser statements.

DPR’s new guidance also incorporates EPA guidance on what a secondary label should contain.  (EPA does not require secondary containers to be labeled, but notes that the applicator remains responsible for following the requirements on the pesticide product’s labeling, and complying with other relevant requirements in the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) and other statutes.)  Although registrants are not required to submit secondary container labels to EPA for review, EPA recommends that the applicator identify the material in the secondary container in the event of a spill to ensure that adequate information regarding the pesticide can be obtained in case of a medical or environmental emergency.  EPA recommends that such labels include the following information:

  • Product name;
  • EPA registration number;
  • Name and percentage of active ingredient of the concentrated product or if known, the percentage of active ingredient in the end-use dilution;
  • If the product in the secondary container is diluted, it should be followed by the phrase:  “The product in this container is diluted as directed on the pesticide product label”;
  • The same signal word as the registered concentrate container label;
  • The same precautionary statements as the registered concentrate container label unless the registrant has acute toxicity data supporting lesser precautionary statements for the diluted product and alternate directions for the diluted product are indicated on the concentrate container label; and
  • The statement:  “Follow the directions for use on the pesticide label when applying this product.”

DPR states:  “If currently registered products have secondary container labels on file with DPR that do not meet the above criteria, registrants should submit revised labels to DPR as an amendment.”

Each submission must include:

  • California Application to Amend Pesticide Product (DPR-REG-035);
  • $25 application fee (payable to:  Cashier, Department of Pesticide Regulation);
  • A copy of the most current EPA stamp-accepted label;
  • Six copies of the concentrate container label; and
  • Six copies of the secondary container label.
    • If the precautionary statement on the secondary container label bears lesser precautionary statements, the submission must be accompanied by acute toxicity data or a reference to data on file with DPR.

As an alternative to submitting revised labels, registrants have the option of requesting that DPR rescind acceptance of the current stamp-accepted secondary container label previously submitted.  Registrants may submit their request in writing on company letterhead to their assigned Regulatory Scientist.  If a secondary container label is inconsistent with the DPR-approved label, DPR will consider the product misbranded, and DPR notes that misbranded products are subject to enforcement action.

Registrants that have previously submitted secondary labels to DPR should review the label in comparison to the DPR-approved concentrate container label and the requirements in this notice.  All inconsistencies must be corrected via amendment submission to DPR or by making a request that DPR rescind acceptance of the current stamp-accepted secondary label so that the product is not considered misbranded and therefore subject to enforcement action.
