What is the purpose of conducting monthly product inventory control?

The purpose of conducting monthly product inventory control is primarily to detect a release. Regular monitoring of inventory levels allows operators to identify discrepancies between the amount of product received and the amount dispensed. If the inventory indicates that more product has been sold or used than what has been delivered, it may suggest a leak in the underground storage tank system. Early detection of such leaks is crucial to prevent environmental contamination, ensure regulatory compliance, and maintain the integrity of the storage system. This proactive approach helps address potential issues before they escalate, safeguarding both public health and the environment.

The other answer choices focus on aspects that are not directly related to the primary aim of inventory control in the context of underground storage tanks. Monitoring employee hours, determining fuel prices, or calculating storage capacity, while relevant in their own contexts, do not serve the critical function of leak detection that monthly product inventory control provides.
