Case Overview

This case study examines a situation involving an industrial plant. The plant is alleged to have emitted excessive amounts of ethylene oxide over a decade (2008-2018). Residents within a two-mile radius of the plant during this time frame developed various types of cancer.

It is claimed that the plant's emissions significantly exceeded the Environmental Protection Agency (EPA) regulations, posing serious health risks to the local community. An expert with extensive knowledge in EPA regulations was sought to review and provide their professional opinion on whether the plant violated EPA emission standards for ethylene oxide during these years.
