ACI 350.3-06, "Seismic Design of Liquid-Containing Concrete Structures and Commentary," provides specific procedures for the analysis and design of environmental concrete structures to withstand seismic events. The standard addresses unique liquid-containing structure (LCS) challenges by calculating impulsive and convective mass components to prevent structural failures, such as shell buckling or roof damage from sloshing.

• SUG I: Low hazard to life (e.g., irrigation reservoirs)
• SUG II: Moderate hazard (standard water storage)
• SUG III: High hazard (wastewater treatment where failure causes environmental disaster or loss of drinking water).

Crucially, the commentary guides the engineer on limiting steel stress to control crack widths. This ensures that even if the concrete stresses are within limits, the structure remains watertight. ACI 350
