What is the maximum distance recommended for slopes where seeps from tanks may occur?

The maximum recommended distance for slopes where seeps from tanks may occur is 3 feet. This guideline is based on ensuring that any seepage from tanks, which can contain hazardous materials or pollutants, does not migrate too far from the source.

Maintaining a distance of 3 feet is crucial to allow for adequate monitoring and management of any potential leakage before it can affect surrounding soil or water sources. This distance helps to minimize environmental contamination and promotes public safety by ensuring that any seepage can be effectively contained and addressed before it can spread further.

The other distance options, such as 2 feet, 5 feet, and 10 feet, either do not provide enough buffer to intervene should seepage occur, or provide too large a distance which may complicate monitoring and containment efforts. Therefore, the recommendation of 3 feet strikes a balance between surety of containment and practical management of the seepage risk.
