How often should fluid storage areas be inspected for leaks?

Inspections of fluid storage areas for leaks should be conducted routinely to ensure that any potential environmental hazards are identified and addressed promptly. This practice is essential in the context of industrial stormwater management because leaks can lead to contamination of stormwater, which may ultimately harm aquatic ecosystems and violate environmental regulations.

Regular inspections allow for the early detection of leaks, thereby minimizing the risk of spills and the associated cleanup costs and liabilities. This proactive approach is a critical component of a facility's compliance strategy and is often required by Environmental Protection Agency (EPA) regulations and state-specific environmental laws.

The other options are not as effective in managing the risks associated with fluid storage. Monthly inspections, while frequent, may not be sufficient if there are changes in operational conditions or weather that could affect storage integrity. Conducting inspections only during the annual audit or in response to complaints is reactive and does not provide the proactive oversight needed to protect the environment and ensure compliance with regulations.
