11. A mechanical line leak detector <br />( ) was <br />( ) was not NA <br />i present in the majority of the pipeline systems used in the evaluation. <br />12. Please specify how much time elapsed between the delivery of product and the start of the <br />data collection: <br />( )oto6h NA <br />( )6to 12h <br />( ) 12 to 24h <br />( ) 24 h or more <br />Temperature Conditions <br />This system was evaluated under the range of temperature conditions specified in Table 1. <br />The difference between the temperature of the product circulated through the pipeline for 1 h or <br />more and the average temperature of the backfill and soil between 2 and 12 in. from the pipeline <br />is summarized in Table 1. If Option 1, 2 or 5 was used a more detailed summary of the product <br />temperature conditions generated for the evaluation is presented in Attachment 4. If Option 3 or <br />4 was used, no artificial temperature conditions were generated. <br />Table 1.

The induced leak rate and the test results used to estimate the performance of this system are <br />summarized in Attachment 5. Were any test runs removed from the data set? <br />(x) no <br />( ) yes <br />If yes, please specify the reason and include with Attachment 5.
