According to NSTM 233, how is seepage tolerated?

• A. Tolerated during operation but cannot pool
• B. Must be eliminated during operation
• C. May pool during operation
• D. Only allowed during maintenance windows

Answer: (A)

Seepage is allowed at a minimal rate during operation, as long as it does not pool. Small leaks from joints or gaskets can occur with normal operation, but pooling would indicate a more serious leak that creates hazards like slippery surfaces, corrosion, or equipment damage. So the best practice is to tolerate non-pooling seepage during operation and address any pooling immediately. The other options imply stricter limits or unsafe conditions (pooling or only during maintenance), which aren’t consistent with this standard.
