5.2.3 ALLOWED DRAINAGE OF UNCONTAMINATED RAINWATER FROM A <br /> DIKED AREA AND (1) KEEP BYPASS VALVES SEALED CLOSED; (11) INSPECT <br /> RETAINED RAINWATER PRIOR TO DISCHARGE,(III)OPEN BYPASS VALVE AND <br /> RESEAL IT UNDER RESPONSIBLE SUPERVISION; (IV)MAINTAIN ADEOUATE <br /> RECORDS OF SUCH EVENTS; OR PROVIDE EQUIVALENCE AS ALLOWED BY <br /> CFR 112.7 (a)(2) (40 C:"FR I I18(c)(3)) <br /> See Section 5.1 above. <br /> 5.2.4 TEST EACH ABOVEGROUND CONTAINER FOR INTEGRITY ON A REGULAR <br /> SCHEDULE OR WHEN REPAIRS WERE MADE; INSPECT CONTAINERS AND <br /> CONTAINER SUPPORTS; OR KEEP RECORDS OF INSPECTIONS AND TEST, OR <br /> PROVIDE EQUIVALENCE AS ALLOWED BY CFR 112.7(a)(2) (40 CFR 112.8(c)(6)) <br /> See Sections 4.9 and 4.11 above. <br /> The Engineer has evaluated the tanks on site for determining the type of inspections necessary <br /> for this site's tank integrity testing. The Engineer has noted that all tanks on site are"shop <br /> built". These tanks are not in direct contact with the ground. The tanks tops, sides and bottoms <br /> can be visually inspected. The tanks and drums in the shops are not exposed to the elements. <br /> The tanks in the covered/bermed area along 2710 Shop's east wall are away from the elements. <br /> The diesel fuel tank has an in-tank probe and an annular-space sensor(that both provide <br /> continuous leak detection monitoring). Considering the Steel Tank Institute's Tank Inspection <br /> Procedure STI SP041, the following tanks and drums would require only periodic visual <br /> inspections by the owner's representative: hydraulic oil drums; grease drums; motor oil tank; and <br /> waste oil tank. Under STI SP001 the diesel fuel tank would require periodic visual inspections <br /> by the owner's representative and external inspection by a certified tank inspector every 20 <br /> years. The Engineer has evaluated that: drums require monthly visual inspection by the Shop <br /> Foreman;the tanks require monthly and annual visual inspections by the Shop Foreman; and the <br /> diesel fuel tank requires an external visual inspection by a certified tank inspector every 20 years. <br /> 5.2.5 PROVIDE EFFECTIVE LEAKAGE CONTROLTHROUGH DEFECTIVE <br /> INTERNAL HEATING COILS,OR PROVIDE EQUIVALENCE AS ALLOWED BY <br /> CFR 112.7(x)(2) (40 CIR 112.8(c)(7)) <br /> Heating coils are not in use at this facility. <br /> JBH Stockton Teraiinal 25 <br />
