The U.S. Department of Transportation regulates all interstate pipelines
Testing is federally mandatedBest practice to confirm the safety
and reliability of the pipeline Safety is our #1 priority Ensure continued superb customer
service
Need for the Test

Hydrostatic Test Remove the natural gas from the line• Controlled release vents harmlessly into
atmosphere• Service is maintained on another system
Test the integrity of the pipeline by filling the line with water• Put the water under pressure for a fixed
period of time

Remove natural gas from the 18” Mainline Completed the week before the hydrotest
Fill the line with waterPressurize the system
Normal operating pressure is 722 PSI Test pressure is up to 1,444 PSI• Relatively short duration (approx. 30 minutes)
Reduce to intermediate pressure at 1,108 PSI•Maintain for 8 hours
How the Test is Performed
![Page 12: Florida Gas Transmission Mainline Hydrostatic Test](https://reader035.vdocuments.us/reader035/viewer/2022062323/56816294550346895dd3074a/html5/thumbnails/12.jpg)

De-pressurize the lineDrain the water from the systemIf any integrity issues are found:
They are corrected as soon as possible The hydrotest is performed again• Any re-testing must be performed within the
prescribed test window timeframeResume normal natural gas service

Safety is our #1 priorityPerformed extensive test
preparations, including an inspection of the entire system
Any pipe anomalies will be repaired in advance of conducting the hydrotest
For the duration of the high pressure test, as a safety consideration, we plan to isolate sections of the pipeline route from people and traffic
Safety During the Test
