What is one of the required procedures for manual inventory reconciliation of existing tanks?

  1. Taking measurements of fuel and water levels in tanks weekly

  2. Using an automated system for daily monitoring

  3. Taking separate daily measurements of fuel and water levels

  4. Conducting monthly inspections of tanks

The correct answer is: Taking separate daily measurements of fuel and water levels

The requirement for taking separate daily measurements of fuel and water levels is crucial for accurate manual inventory reconciliation. This process helps maintain precise records of product levels within the tanks, allowing operators to identify discrepancies caused by leaks, spills, evaporation, or incorrect deliveries. By measuring both fuel and water separately on a daily basis, operators can effectively monitor changes and ensure that any variations are accounted for promptly. This frequent data acquisition supports the integrity of inventory records and assists in compliance with safety and regulatory standards, thereby minimizing potential environmental impacts and financial losses due to inaccuracies.
