Who is Florida Gas Transmission (FGT)?
Why is FGT testing?What is the test exactly?When will the test occur?Where will the test take place?How will the test be conducted?How will the test affect me?
Today’s Outline
2
Natural gas transmission company operating a 5,000 mile pipeline system along the Gulf
Provide majority of the natural gas for power generation in Pinellas County
10-inch diameter pipeline serving Tampa area
Customers include: Electric utility companies Local distributors Industrial clients
Florida Gas Transmission Company

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 client service
Need for the Test
4
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
Nature of the Test

Remove natural gas from the pipeline Completed the week before the hydrotest
Fill the line with waterPressurize the system
Normal operating pressure is 712 PSI Test pressure is up to 1,500 PSI• Relatively short duration (approx. 30 minutes)
Reduce to intermediate pressure at 1,350 PSI•Maintain for 8 hours
How the Test is Performed
11
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 will be performed as soon as
possible, during the same hours
Resume normal natural gas service
How the Test is Performed (con’t)
12
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
