How frequently must internally lined tanks be inspected to ensure the lining is performing according to original design specifications?

Once every year
Twice every year
At least once every 3 years
Only when issues are identified

The correct answer is: At least once every 3 years

Internally lined tanks are critical in preventing leaks and protecting the environment from hazardous substance spills. According to regulations and best practices, these tanks must be inspected at least once every three years to ensure that the lining remains intact and effective. Regular inspections help identify any deterioration, excessive wear, or failure of the lining that could compromise the tank’s structural integrity and its ability to prevent leaks. This inspection frequency is designed to provide a sufficient window to catch potential issues before they lead to significant problems, ensuring that the lining continues to perform according to its original design specifications. By adhering to this schedule, operators can maintain compliance with federal and state regulations and minimize the risk of environmental contamination.
