What is the true statement regarding spill and overfill controls?

Spill and overfill controls are essential safety measures in the management of underground storage tanks (USTs) to prevent environmental contamination and ensure compliance with regulations. Delivery personnel play a critical role in this process because they directly oversee the transfer of fuel into the UST.

When fuel is delivered, it is the responsibility of the delivery personnel to monitor the filling process closely, ensure that appropriate measures are in place to prevent spills and overfills, and respond promptly in case of any issues. Effective training and awareness among delivery drivers regarding these controls are crucial for preventing accidents that may lead to environmental harm and costly clean-up efforts. This vigilance helps safeguard both the environment and public health.

The other options suggest a misunderstanding of the responsibilities associated with spill and overfill controls. They are not optional for delivery drivers; they play a significant role in its management. Additionally, while the UST owner does have responsibilities, spill and overfill controls necessitate active participation and vigilance from various stakeholders, including delivery personnel. Local authorities may provide regulations and oversight, but they are not solely responsible for enforcing spill and overfill controls on-site during fuel deliveries.
