EPA Superfund Site

PETRO-PROCESSORS OF LOUISIANA, INC.

LA | EPA ID LAD057482713

Exposure status: insufficient data

About this site’s exposure pathways: As of August 2025, there is still insufficient information to make a determination on HEUC at the Petro-Processors Superfund Site. The site was finalized on the NPL in September 1984.

EPA has determined that there is insufficient data to make a Human Exposure evaluation (HEID). The planned activities to collect sufficient information to make a human exposure evaluation are to have the Potentially Responsible Party (PRP) perform a Vapor Intrusion (VI) Risk Evaluation at a commercial structure located over the groundwater plume. EPA currently anticipates that there will be sufficient data to make a Human Exposure determination by September 2026.

Data limitations: Proximity to a Superfund site boundary does not mean your property is contaminated. EPA site boundaries show the area designated for cleanup, not the full extent of contamination. Groundwater plumes can extend beyond site boundaries. This tool shows publicly available EPA federal data. It is not affiliated with or endorsed by EPA, and is not a substitute for a professional environmental assessment.
