No leaks or repairs requiring <br /> attention were noted during on-site inspection. All seismic calculations show that the lateral <br /> seismic restraint of the tanks are acceptable and have been designed correctly. <br /> ' American Society of Civil Engineers 7-10,Minimum Design Loads for Buildings and Other Structures, Section <br /> 15.4.1 <br /> Responsive ■ Resourceful ■ Reliable <br />
