The operational vent must be installed on the Tank's primary compartment. The inspector observed an <br /> undersized operational vent installed on the Tank.Adequate operational venting is required for continued <br /> service of the Tank. Install at minimum, a single 4-inch diameter operational vent, with no reduction in pipe <br /> diameter, on a minimum 4-inch diameter Tank port. <br /> Operational vent was replaced with a like item since it was expired. Originally that's what we thought we had to <br /> do. So I am working with the contractor right now,to make sure that we get this fixed correctly. <br /> After talking to our contract company(Confidence UST Services)they are stating that they do not make a 4" PV <br /> Vent. Do you know why it is being required if they do not make it? <br /> 2. The inspector noted that Tank shells and piping surfaces had areas of paint failure.The coating of Tank shells <br /> and piping should be maintained intact. Failed coating and surface rust and should be removed,followed by <br /> application of a protective coating for continued service of the Tank. <br /> Paint is in the process of being ordered. We have ordered all new signs for the tank as well. <br /> 3. The liquid level gauge read approximately one foot, 9.5 inches and manual liquid level measurement was one <br /> foot, 7.5 inches. Calibrate the liquid level gauge to a difference of one inch or less from the manual <br /> measurements. <br /> This has been calibrated by our contractor. <br /> i <br />
