In $1989,$ the three engineer$/$managers were tried and convicted of illegally storing, treating and disposing of hazardous wastes. There was no indication that these three were the ones who actually handled chemicals in an unsafe manner, but as managers of the plant, the three were ultimately responsible for how the chemicals were stored and for he maintenance of the safety equipment. The potential penalty for these crimes was up to $15$ years in prison and a fine of up to $$750,000.$ Gepp, Dee and Lentz were each found guilty and sentenced to three years' probation and $1,000$ hours of community service. The relative leniency of the sentences was based partly on the large court costs each had already incurred.
