Florida Gas TransmissionMainline Hydrostatic Test
From the Golden Glades Interchange to the interchange of NW 122nd Street
with the Palmetto Expressway Miami-Dade County
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
Natural gas transmission company operating a 5,000 mile pipeline system along the Gulf
Provide 65% of all the natural gas for power generation in Miami-Dade County
18” diameter Mainline serving South FloridaCustomers 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 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
Nature of the Test
Hydrotesting the 18” Mainline systemStandard, common pipeline test
procedureRecent, successful 18” Mainline tests
were completed in: Saint Lucie Martin Palm Beach Broward

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
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
How the Test is Performed (con’t)
Safety is our #1 priorityPerforming extensive test
preparations, including an inspection of the entire system
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
Advance Preparations Make all key stakeholders aware• Adjacent property owners• Emergency service providers•General driving public
Announcements• Flyers, newspaper, FL511, website, etc.
Dynamic message signs• 2 weeks in advance
Conducting the Test
Night of the Test Begin at midnight Close ramps/roads/lanes with barricades Law enforcement support Confirm all-clear along the 10.2-mile
corridor Conduct hydrotest Reopen roadways at approximately 4:00
AM
Conducting the Test (Con’t)
General Utility Permit from the Florida Department of Transportation is in process
Officers will be stationed at ramp and road closures and at detours
Traffic will be detoured from: Turnpike I-95 Palmetto Expressway
