California UST System Operator Practice Test 2026 – Comprehensive All-in-One Exam Preparation Guide

The primary focus of spill control measures in underground storage tank (UST) systems is environmental protection. This is critical because USTs often store hazardous materials that can negatively impact the environment if a leak or spill occurs. The implementation of spill control measures aims to prevent contamination of soil and groundwater, safeguard ecosystems, and protect public health.

Regulatory frameworks and best practices prioritize minimizing risk factors associated with spills, making environmental protection a key objective. While cost management, public relations, and employee training are also important considerations in the overall operation of UST systems, they serve as supporting functions rather than the central focus of spill control measures. Effective environmental protection strategies directly lead to better compliance with regulations and reduced liability, emphasizing the priority of maintaining ecological integrity in UST operations.
