Report: Evaluation of EPA Policies, Procedures, and Processes for ASPECT Flight Missions

Report # 25-E-0034, June 2, 2025
Why We Did This Report

The U.S. Environmental Protection Agency Office of Inspector General conducted this evaluation to determine whether the EPA and its contractors followed Airborne Spectral Photometric Environmental Collection Technology flight equipment deployment procedures during the East Palestine, Ohio train derailment emergency.
 

Summary of Findings

During its response to the train derailment, the EPA and its contractors followed existing practices for deploying the ASPECT aircraft. Although the EPA followed existing practices for deploying ASPECT, the documented procedures that were in place remain largely unknown to all involved stakeholders and lack the clarity needed to avoid negatively affecting decision-making related to an emergency response.
