22 August 2011 AGE-NC Project No. 11-1934 Page 4 of 6 secondary compartments are typically manufactured [22CCR§66264.193(e)(3)] from A36 steel with gauge and thickness discussed in Section 2.1.3. The approximate rectangular AST width, length and height are 33-inch, 107 '/2-inch and 39-inch, respectively. The AST ancillary equipment is discussed in Section 2.1.4. 3.2. VISUAL INSPECTION The visual inspection [22CCR§66264.193(e)(2)] of the AST was conducted by an AGE representative on 22 June 2011 . The AST exterior surface did not reveal signs of leaks, corrosion, weld cracks; weld breaks or scrapes in coating which may cause a release from the AST system. A visual assessment summary is included as Table 3 4.0. HYDROSTATIC TEST The hydrostatic test[22CCR§66265.192(k)(10)] is conducted to verify the AST primary and secondary shell will not leak. The test was conducted by representatives of AGE on 22 June 2011. Test results are provided in Table 4. 4.1 . HYDROSTATIC TEST PROCEDURE The six AST primary and secondary compartment ports are temporarily sealed to maintain an inner constant pressure. A regulator with pressure valve was attached to one opening of the primary and secondary AST compartment. Air pressure was applied with a compressor ranging between approximately 2.5 pounds per square inch (psi)and 3 psi;first to the primary and then to the secondary. The approximate AST ports and respective locations are shown on Figure 3. 4.2. HYDROSTATIC TEST RESULTS The hydrostatic test results indicated both the primary and secondary AST shells did not leak at the time of the test. Pressure readings were collected every fifteen minutes for one hour from the primary. Testing of the secondary followed successful results from the primary tank test. No fluctuation in pressure was recorded during the test. Test results are provided in Table 4. Advanced GeoEncironmental,Inc.
