30 March 2019 AdvancedGeo AGE Project No. 10-1787 Environmental Page 4 of 6 • Waste oil catch pans. • Inline pump. • Waste oil conduit piping. 3.2. VISUAL INSPECTION — 22 CCR § 66264.193(e)(2) A visual inspection of the tank and its affiliated pumps, piping, ancillary equipment, interior surface and exterior surface did not reveal signs of leaks, corrosion, weld cracks or breaks or scrapes in coating which may cause a release from the tank system. There were no discrepancies noted at the time of the AST visual inspection. Figure 3 shows the top view of the tank with appurtenances. A visual assessment summary is included in Table 3 4.0. HYDROSTATIC TEST On 15 January 2019, the hydrostatic (pressure) test was conducted to verify the AST primary and secondary shell will not leak. The test was conducted by a representative of AGE on 15 January 2019. Test results are provided in Table 4. 4.1. TEST PROCEDURES A total of six AST primary and secondary compartment ports were temporarily sealed to maintain an inner constant pressure. A regulated pressure valve was attached to one opening of the primary and secondary AST compartment. Air pressure was applied with a compressor to 3-pounds per square inch (psi)for a half hour to the primary compartment and then an additional half hour to the secondary compartment. The AST ports are shown in the manufacturer technical specification included as Appendix A and on Figure 3. 4.2. 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 five minutes for one hour. No fluctuation in pressure was recorded during the test. Test results are provided in Table 4. 5.0. SEISMIC ANALYSIS A seismic analysis was provided to verify the AST will not tip or turn over during a seismic event. Seismic data used in the calculation is included in Table 2. The calculations are included as Appendix B.
