My boss owned a very respected chrome shop in the 80s. He did a production run for a customer that required a certain chemical. After the run, he stored the chemical in a couple plastic barrels in the corner of the shop. The OSHA inspector said it was OK. A few weeks later, the EPA guy stopped in. He said it was stored "improperly" . Boss said, nothing has leaked? EPA said, we dont know that. Long story short, when the lawyers for the EPA got done my boss had to sign a swore statement he would NEVER operate a chrome shop again. They sued him for MILLIONS. He had to pay for soil sampling for several years. He owed the government money for over a decade. Over something that "COULD" have been a spill.
