What type of maintenance is essential for underground storage tanks to mitigate risks?

Regular visual inspection is essential for underground storage tanks because it allows for the early detection of potential issues that could lead to leaks or failures. This type of maintenance involves checking for signs of corrosion, damage, or any unusual conditions that could affect the integrity of the tank. By conducting these inspections routinely, operators can identify and address problems before they escalate into more severe environmental hazards or compliance issues.

Visual inspections help in ensuring that safety features are intact and functioning properly, which is critical in preventing contamination of soil and groundwater. It also provides an opportunity to verify that all components, including piping and containment systems, are in good condition.

While seasonal cleaning, weekly operational testing, and daily monitoring each serve their purposes, they do not replace the need for regular visual assessments that focus on the tank's physical condition. For instance, seasonal cleaning ensures that the space around the tank is clear of debris, and operational testing verifies that systems are functioning correctly. Daily monitoring often involves checking levels and detecting leaks through electronic means, but none of these actions replace the hands-on assessment provided by regular visual inspections. This practice is foundational to responsible UST management and environmental protection.
