UST Tree Walk (Corrective Action) | Board Exam 2025| Questions with Verified Solutions What are the key indicators that an underground storage tank system might be leaking during a tree walk inspection? Look for signs of soil discoloration, unusual vegetation growth, or any unusual odors around the tank and its components. How should an inspector document the findings during a tree walk for UST inspections? Document all observations, including the location of potential leaks, the condition of the surrounding vegetation, and any other environmental impacts. During a tree walk, what signs suggest that the containment system of a UST is compromised? Look for visible cracks or damage in the containment area, pooling of liquids, or soil erosion near the tank. How can an inspector determine if the tank is properly grounded during a tree walk inspection? Check the grounding system for any visible damage, rust, or disconnects, ensuring all connections are intact and properly secured. What action should be taken if an inspector identifies signs of contamination during a tree walk? 2 The inspector should report the contamination to the appropriate authorities immediately and recommend remedial actions. What is the significance of checking vegetation during a tree walk around a UST system? Certain vegetation changes, such as unusually lush or stunted plant growth, can indicate the presence of leaks or soil contamination from the UST. How do you assess the integrity of the piping connected to the UST during a tree walk? Inspect the visible piping for signs of wear, corrosion, or physical damage that could lead to a release. Why is it important to assess the slope and grading around the UST site during a tree walk? Proper slope and grading ensure that any potential spills or leaks do not flow toward sensitive areas like water bodies or underground aquifers. What is the purpose of checking for standing water during a tree walk inspection? Standing water near the UST could indicate a leak, as leaking liquids may accumulate and create puddles or wet areas. How should an inspector check the security of the UST system during a tree walk? Ensure that access points, such as tank covers or valves, are secure and that there is no unauthorized access or tampering. 3 What should be done if a tree is found growing near the UST system during a tree walk? The roots of trees can damage underground systems. The tree should be evaluated, and if necessary, removed to prevent potential damage to the UST components. During a tree walk, how can an inspector verify that the secondary containment system is functioning? Check the secondary containment for any signs of fluid accumulation or leaks, ensuring it is intact and capable of containing any releases. What are the typical consequences of failing to conduct proper tree walk inspections on UST systems? Neglecting tree walk inspections may result in undetected leaks, environmental contamination, and failure to meet regulatory compliance. How can an inspector verify the presence of a sump in the UST system during a tree walk? Check for a sump at the tank’s base or within the containment area, ensuring that it is free from debris and capable of collecting any leaked fluids.
