The plant was located in an industrial area that had several pipelines in the general geographic area including a crude oil pipeline leading to a refinery, and a pipeline carrying pesticides to be processed and redistributed to local farms in the area. In July 2014, Ajay Patel, the logistics general manager received notification that there were some minor leaks along the pipeline that were being fixed. Workers in the area had experienced sudden headaches and lightheadedness and the company immediately moved to investigate the leak and address faulty seams that had eroded and weakened. The flow of naphtha was temporarily stopped for 72 hours so two portions of the pipeline could be removed, and the eroded portions replaced.
