EPA Launches New Electronic Confidential Statement of Formula Application

This original announcement was published by the EPA on May 12, 2021. Click here for more information.


The U.S. Environmental Protection Agency (EPA) is launching an electronic Confidential Statement of Formula application (eCSF builder) to support pesticide registration applications. The new electronic tool is consistent with the agency’s desire to continuously improve and modernize internal processes and digital workflows.

To register a new pesticide product with EPA, companies must submit a Confidential Statement of Formula (CSF) application. The form lists all the product’s components and their percent by weight along with various additional information.

Currently, CSF applications must be submitted to EPA in hard copy. The new eCSF builder will automatically validate certain data in a CSF application prior to submission to EPA. This functionality, along with real-time validation of chemical ingredients through EPA’s Substance Registry Service, will make the pesticide registration process more efficient, saving EPA and registrants time and resources. While paper CSF forms remain available, EPA recommends submitting applications electronically as the review of paper applications could be a longer process.

Users can access the eCSF builder and provide feedback through the Central Data Exchange.

EPA Extends Respiratory Protection Flexibilities for Agricultural Pesticide Handlers During COVID-19

The U.S. Environmental Protection Agency (EPA) is committed to protecting the health and safety of Americans, especially during the COVID-19 public health emergency. In June 2020, EPA issued temporary guidance regarding respiratory protection requirements for agricultural pesticide handlers that offers flexibility during the COVID-19 public health emergency.

Due to the continued concerns regarding personal protective equipment shortages in the agricultural sector, EPA is extending the “annual fit test delay” to September 30, 2021 as part of the previously issued guidance on respiratory protection requirements for agricultural pesticide handlers. This revision is in alignment with Occupational Safety and Health Administration memos on respirators and addresses Agricultural Worker Protection Standard (WPS) requirements under the Federal Insecticide, Fungicide, and Rodenticide Act.

The remainder of the June 2020 guidance remains in effect. EPA will assess the continued need for and scope of the temporary guidance on a regular basis.

Attend EPA’s Webinar about the Experimental Use Permit for the Oxitec Genetically Engineered Aedes aegypti Mosquitoes

This original announcement was published by the EPA on April 30, 2021. Click here for more information.


On May 5, 2021, EPA will host a webinar for the public to learn about the approval of an experimental use permit (EUP) to allow Oxitec Ltd. to field test the use of genetically engineered Aedes aegypti mosquitoes as a way to reduce mosquito populations.

Like all pesticides, Oxitec’s mosquitoes, genetically engineered for population control, are regulated under the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA). To be approved for an EUP or registration under FIFRA, pesticides must be shown to not cause unreasonable adverse effects to humans or the environment. Data submitted by Oxitec have demonstrated that genetically engineered Aedes aegypti mosquitoes meet the FIFRA approval standard.

The EUP contains significant protections, including weekly monitoring and sampling of the mosquito population in the treatment areas, that also enabled the agency to determine the product meets the FIFRA safety standard. Additionally, it’s important to note that only adult male genetically engineered Aedes aegypti mosquitoes will be present in the environment and they do not bite people, further supporting EPA’s finding that the mosquitoes are not expected to present risks to human health. If an unforeseen event occurs, EPA has maintained the right to cancel the EUP at any point during the 24-month period.
