Upon receiving a completed 24(c) product registration packet for an EPA registered product the State of Minnesota can begin the registration process. The MDA reviews the application package to ensure it is complete and meets both state and federal requirements:

• State:
  1. the pesticide's composition warrants the proposed claims for the pesticide;
  2. the pesticide's label and other material required to be submitted comply with this chapter;
  3. the pesticide will perform its intended function without unreasonable adverse effect on the environment;
  4. the pesticide will not generally cause unreasonable adverse effects on the environment when used in accordance with label directions; and
  5. a special local need for the pesticide exists.
• Federal:
  1. Special Local Need
  2. The additional use is covered by necessary tolerances or other clearances under the Federal Food, Drug, and Cosmetic Act (FFDCA).
  3. Registration for the same use has not previously been denied, disapproved, suspended, or canceled by the Administrator, or voluntarily canceled by the registrant
  4. The state has determined that it will not cause unreasonable adverse effects on man or the environment

• The MDA may request additional information.
• MDA review staff present their findings to management.
• The final decision is made by the MDA commissioner.
• After issuing a SLN registration, the MDA is then required by federal regulations to notify the EPA. EPA has 90 days from the effective date to disapprove the SLN registration (the SLN registration is valid during the 90-day EPA review period).
• SLN registrations and labels are given an expiration date typically one growing season in length up to five years from the approval date.

Once a 24(c) is within six months from its expiration date, the registrant is responsible for notifying the State of Minnesota if they want to request an extension to the expiration date or let the registration expire.

• Technical experts and commodity groups should keep track of expiration dates and inform the registrant of the need for renewal.
• If there is still a need, new support letters should be drafted addressing any new alternative products.

In order to request an extension past the label expiration date, the registrant will need to submit a new 24(c) registration packet in full, restarting the process from the beginning. This is to ensure a special local need still exists and a registration is still warranted.

PFAS are manufactured chemicals that have been in use for decades. Some examples of common consumer and industrial products that may contain PFAS include carpeting, upholstery, waterproof clothing, food packaging, cookware, and fire-fighting foam. PFAS can be released into the environment during the production, use, and disposal of PFAS-containing products.

Research into the effects of PFAS on human health is ongoing. Visit the Minnesota Department of Health (MDH) website for information on PFAS and Health.

In 2023, the Legislature passed two bills with significant language on PFAS, SF 1955 and HF 2310. These bills outline the process for prohibiting the sale and distribution of products containing intentionally added PFAS. The MDA and the Minnesota Pollution Control Agency (MPCA) will work in partnership to implement portions of these new laws. Minnesota’s PFAS Blueprint (pdf), developed by multiple state agencies, further identifies strategies for preventing, managing, and cleaning up PFAS found throughout the state.
