Case Study 1: The Tank that Stank

During a Phase I ESA, evidence of an underground storage tank (UST), including a fuel gauge, supply and return lines, and an apparent fill port, were identified at an office building. The consultant was hired to perform a tank tightness test on what was believed to be a UST fill port in front of the building. The test was performed and failed. Our review of the Phase I report and a brief site inspection revealed that the alleged fill port was in fact a sewer vent, a distinction that most people who are familiar with basic plumbing can make, and any assessor should be able to easily identify.

I hope that this case story, and future case stories and insights, will help readers to gain valuable industry insights. I’m always interested in hearing others’ stories, so comments are welcome!
