How does age affect UST systems and their maintenance requirements?

The correct choice highlights the importance of regular inspections for older UST systems. As tanks age, the materials they are made of, such as steel or fiberglass, can degrade due to environmental factors like corrosion, chemical reactions, and structural issues. This degradation can increase the likelihood of leaks and failures, presenting risks to the environment and public health.

Older tanks may develop issues at a higher rate compared to newer systems, underscoring the necessity for more frequent inspections. Ensuring that these inspections occur not only helps identify potential problems early on but also aids in maintaining compliance with regulatory standards. By performing regular assessments, owners can manage the risks associated with aging tanks and maintain the integrity of the UST systems, ultimately protecting both the environment and their investment.

The other options do not align with industry experiences or regulations. Stating that age has no effect on maintenance ignores the well-documented impacts of corrosion and wear over time. Suggesting that older tanks can be ignored dismisses the potential hazards they pose and the responsibility of owners to manage and mitigate risks. The assertion that all tanks need yearly upgrades is an overgeneralization; while maintenance is essential, the need for upgrades can depend on specific circumstances and regulations applicable to each tank.
