Which of the following is not a "new underground storage tank"?

1. 12,000 gallon unleaded fuel tank installed in 2003 at a retail sale location

2. 500 gallon waste oil tank installed in 1995 on a military base

3. 10,000 gallon diesel tank installed in 1982 at a trucking fleet operation

4. 1,500 gallon diesel tank installed in 2001 on a farm

The correct answer is: 10,000 gallon diesel tank installed in 1982 at a trucking fleet operation

The choice indicating the 10,000 gallon diesel tank installed in 1982 at a trucking fleet operation is correctly identified as not being a "new underground storage tank." According to regulatory definitions, a "new underground storage tank" typically refers to tanks that are installed after specific regulatory cut-off dates which have changed over the years as environmental standards have evolved. In this case, the tank installed in 1982 predates many of the significant regulations that were introduced in the late 1980s and beyond concerning the installation and operation of underground storage tanks. Therefore, it does not classify as a new tank under the current definitions. The other options present tanks that were installed either in the late 1990s or early 2000s, making those relevant concerning today’s definitions and regulations for "new" tanks. Understanding the timeline of regulations regarding underground storage tanks is crucial for interpreting what qualifies as "new."
