volume or fraction thereof. When testing a system having a volume less than 10 cubic feet or a <br />system in a single-family dwelling, the test duration shall not be less than 10 minutes. The <br />duration of the test shall not be required to exceed 24 hours. <br />Atmos Energy uses the CFR Code 192 Rule for testing a gas piping system. This requires Atmos <br />to only test to what a normal usage pressure would be. For most structures in Paris, this would be <br />only 4 oz. of pressure for 1 minute. By contrast, the minimum pressure the City test requires is <br />3 pounds pressure for 30 minutes. <br />Between 1-1-2011 and 6-30-11 Atmas tested 620 structures of which 33 (5.32%) failed the test. <br />By contrast, the City required test (by a licensed plumber) from 8-10-11 through 2-3-11 of 263 <br />structures resulted in 51 failures (19.39%). The City required test is more likely to detect a faulty <br />system. <br />This would appear to be a public safety policy decision. Would the change from the current 30 <br />day testing requirement to a 90 testing requirement endanger the public? Would the piping <br />system be more likely to fail if it has been off three times as long? <br />The staff is requesting that the Council determine if it wishes to retain the current 30 day policy <br />or change it to a 90 policy. <br />028 <br />
