Which factor is crucial for maintaining compliance with UST regulations?

Proper training of personnel handling underground storage tanks (USTs) is critical for maintaining compliance with UST regulations. Well-trained staff are more knowledgeable about the regulatory requirements and best practices for operating and maintaining UST systems. This understanding is essential for preventing leaks, spills, and other potential environmental hazards that can result from improper handling or maintenance of these systems. Additionally, trained personnel are better equipped to perform necessary inspections and report issues promptly, which is vital for regulatory compliance.

Frequent changes in regulatory policies may also affect compliance but without adequately trained personnel to interpret and implement these changes, compliance efforts may falter. Lowering maintenance costs and reducing tank sizes can be considered but do not directly address the knowledge and practices required to adhere to regulations effectively. The emphasis on personnel training highlights the human element, which is fundamental in the execution of safe operational procedures and regulatory adherence for UST systems.
