• A. Quarterly
• B. Annually
• C. Monthly
• D. Biannually

Answer: (A)

Regular exterior inspections of the tank and its support elements should be done on a quarterly basis. This cadence keeps watch for obvious damage or weakening from weather, corrosion, impact, or wear on the tank shell, supporting structure, vents, foundation, and any catwalks or ladders before problems develop into leaks or structural failures. Monthly checks would be more frequent than needed for static exterior components and could waste resources, while annual or biannual intervals risk letting issues progress. If severe weather hits or there are known corrosion risks, perform additional checks beyond the quarterly schedule.
