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 client service
Need for the Test
Hydrostatic Test Remove the natural gas from the line• Controlled release vents harmlessly into
atmosphere• LDC-service is continued on parallel loop
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 Palm Beach
Began Miami-Dade testing February 2011
Background
Martin Broward

Test Preparation February – MarchConduct Hydrotest March 29 – April 26, 2012
Test window has tentatively been set: March 29 – April 26, 2012 Coordinated with FP&L and regulators
Project Schedule
Total Project Length = 2.2 miles Begin: W 39th Street (NW 91st Terrace) End: NW 64th Street
Generally follows 3 roadway alignments: Palmetto Expressway (SR 826) & W 20th Ave Hialeah Expressway (SR 934) & NW 74th St Milam Dairy Road (NW 72nd Ave / SR 969)

Project Location (con’t)
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 pressure to 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 will be performed as soon as
possible, during the same hoursResume normal natural gas service
How the Test is Performed (con’t)
Safety is our #1 priorityPerformed 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 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 cross streets with barricades Law enforcement support Confirm all-clear for entire 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
Emergency responders will be able to cross as needed
Officers will be stationed atmajor cross street detours
