On November 22, 2024, the U.S. Environmental Protection Agency announced it made available more than 4,500 Data Evaluation Records (DERs) in ChemView, a public portal that houses data and review of toxic chemicals. A DER is the documented EPA review of studies submitted during the request to register a pesticide or during the registration review process, and does not contain confidential business information. The studies may include product chemistry, toxicology, ecological effects, human exposure, spray drift, environmental fate, and residue chemistry.

EPA has not routinely released most DERs to the public. Prior to today’s announcement, to obtain a DER not included as part of EPA’s registration review docket, including most product chemistry DERs, a requester would need to submit a Freedom of Information Act (FOIA) request separately for each DER. Releasing this batch of DERs that have previously been requested through the FOIA process, which are largely product chemistry DERs, aims to reduce the need for submitting FOIA requests for these DERs in the future.

To access DERs in ChemView, select ″EPA Assessments″ in the output selection box. Results can be filtered using an EPA-issued study number with the document information filter, or product code with the chemical identifier filter. EPA plans on exploring ways to proactively add DERs to ChemView as they are developed. from agropages
