The regulatory agency that oversees all petroleum storage tanks in Michigan is the Storage Tank Division for the Bureau of Fire Services, regardless if it is an UST or AST. If you are responsible for a standard emergency generator system, this agency will inspect everything related from the main fuel storage tank (belly tank, AST, UST) as well as the interior fuel system (day tank, emergency vents, fire-link valves, fuel lines, fire rated generator fuel hoses). Michigan simplifies its regulatory oversight by placing all petroleum storage tank responsibilities under one agency; however this can also increase your compliance exposure when the Inspector will want to examine the entire fuel system inside and out, in one visit.

Understanding the regulations and maintaining a compliant fuel system can be difficult and overwhelming. For assistance and a review of your fuel system to ensure you ready when an Inspector arrives, please Contact Us.
