How frequently must internally lined tanks be inspected to ensure proper performance?

Internally lined tanks must be inspected every 3 years to ensure proper performance. This regular inspection schedule is critical to maintaining the integrity of the lining, identifying any potential issues such as wear, degradation, or corrosion that could compromise the tank's ability to safely hold hazardous substances. The three-year interval helps operators address any maintenance needs before they lead to more serious problems, thereby enhancing safety and environmental protection.

This frequency aligns with industry best practices, regulatory standards, and guidelines set forth by environmental protection agencies, emphasizing the importance of proactive maintenance and inspection to prevent leaks and spills from tanks, which can have severe environmental and regulatory consequences. Regular inspections are essential for verifying that the internal lining remains effective and meets the necessary performance standards.
