The correct answer is determined by industry standards and practices regarding the installation of underground storage tanks (USTs). The minimum distance that a bottom hold down pad should extend beyond the sides and ends of the tank ensures stability and structural integrity, particularly in preventing shifts due to external forces or environmental factors.

In this case, extending the pad 18 inches beyond each side and 12 inches beyond each end provides sufficient anchoring to support the tank while accounting for movement and pressure from soil and other external elements. This dimension also helps to manage any potential forces acting on the tank during filling or emptying, while ensuring that the tank remains securely in place. Proper anchoring is crucial to minimize risks associated with leaks, spills, and environmental contamination, which underscores the importance of adherence to these specifications.
