Washington State Underground Storage Tank (UST) Site Assessment Certification Practice Test

The objective of preventive maintenance for underground storage tanks (USTs) is fundamentally focused on minimizing the risk of leaks or spills through regular inspections, repairs, and upgrades. This proactive approach is crucial because leaks and spills can have severe environmental consequences, pose health risks, and lead to substantial financial liabilities for tank operators. By engaging in routine checks and maintenance activities, operators can identify potential issues before they become significant problems, ensuring that the systems remain compliant with environmental regulations and safe for public health.

Regular inspections also provide an opportunity to address wear and tear and implement necessary upgrades, ultimately safeguarding the UST's integrity and functionality. This not only protects the environment but also enhances the reliability of the tank system, supporting the overall sustainability of fuel operations.
