ail C H- U 11. A mechanical line leak detector ( ) was NA ( ) was not present in the majority of the pipeline systems used in the evaluation. 12. Please specify how much time elapsed between the delivery of product and the start of the data collection: NA ( )0to6h ( )6to 12h ( ) 12 to24h ( ) 24 h or more Temperature Conditions This system was evaluated under the range of temperature conditions specified in Table 1. The difference between the temperature of the product circulated through the pipeline for 1 h or more and the average temperature of the backfill and soil between 2 and 12 in. from the pipeline is sutntnarized in Table 1. If Option 1.2 or 5 was used, a more detailed summary of the product temperature conditions generated for the evaluation is presented in Attachment 4. If Option 3 or 4 was used, no artificial temperature conditions were generated. Table 1.

Data Used to Make Performance Estimates 13. The induced leak rate and the test results used to estimate the performance of this system are summarized in Attachment 5. Were any test runs removed from the data set? (X)no ( ) yes If yes, please specify the reason and include with Attachment 5. (If more than one test was removed, specify each reason separately.)
