The Environmental Protection Agency (EPA) is extending the expiration deadline of existing Federal, state, territory, and tribal certification plans. This deadline was established in 2017 when the EPA promulgated a final rule revising the Certification of Pesticide Applicators (CPA) regulations to improve the competency of certified applicators of restricted use pesticides (RUPs), increase protection for noncertified applicators using RUPs under the direct supervision of a certified applicator through enhanced pesticide safety training and standards for supervision of noncertified applicators, and establish a minimum age requirement for certified and noncertified applicators using RUPs under the direct supervision of a certified applicator. Federal, state, territory, and tribal certifying authorities with existing certification plans were required to revise their existing certification plans to conform with the updated Federal standards for the certification of applicators of RUPs and submit their revisions for EPA review in March 2020. The existing plans are set to expire on March 4, 2022, unless the revised plans are approved by the Agency. EPA is extending the existing plans' expiration deadline to November 4, 2022. This will allow additional time for proposed certification plan modifications to continue being reviewed and approved by EPA without interruption to federal, state, territory, and tribal certification programs or to those who are certified to use RUPs under those programs. The extension also provides EPA with additional time to issue a proposed rule and seek public comment on the need for extending the expiration date beyond November 4, 2022.
