(7) Before being covered, enclosed, or placed in use, all <br /> underground storage tanks and piping shall be tested <br /> for tightness Aydrostetteslly or with sir pressure at <br /> not less than 3 pounds per square-inch (20.60 k Pa) and <br /> not nor* then 5 pounds per square-inch (34.48 k Ps). <br /> Pressure piping shall be hydrostatically tested to 150 <br /> percent of the maximum anticipated pressure of the <br /> system, or pneumatically tested to 110 percent of the <br /> maximum anticipated pressure of the system. but not ; <br /> less than 5 pounds per square inch (34.48 kPa) Rouge at <br /> the highest point of the system. This test shall be <br /> maintained for a sufficient tine to complete visual <br /> inspection of all Joints and Connections, but for at <br /> least 10 minutes.
