1 Florida Gas Transmission Section #1 Hydrostatic Test 14-Inch Saint Petersburg Lateral Pipeline From Compressor Station 30 (Plant City West) to Main Line Valve (Tampa East Regulator) Hillsborough County

2 Today s Outline 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? 1

3 Florida Gas Transmission Company Natural gas transmission company operating a 5,000 mile pipeline system along the Gulf Provide majority of the natural gas for power generation in Hillsborough County 14-inch diameter pipeline serving Tampa area Customers include: Electric utility companies Local distributors Industrial clients 2

4 Need for the Test The U.S. Department of Transportation regulates all interstate pipelines Testing is federally mandated Best practice to confirm the safety and reliability of the pipeline Safety is our #1 priority Ensure continued superb client service 3

5 Nature of 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 4

6 Hydrotesting the 14-inch lateral system Standard, common pipeline test procedure Recent, successful pipeline tests were completed in: Miami-Dade Saint Lucie Palm Beach Background Martin Broward Hillsborough testing began in September

7 Project Process Begin Project Obtain Permits Prepare System for Testing Conduct Hydrotest End Project Public Awareness Campaign 6

8 Project Schedule TASK Community Awareness Permit Applications System Preparation Test Preparation DATE July October June July July August August September Conduct Hydrotest 3 October 2014 Test window is set: Friday, 3 October 2014 Early morning, midnight 4:00 a.m. 7

11 How the Test is Performed Remove natural gas from the pipeline Completed the week before the hydrotest Fill the line with water Pressurize the system Normal operating pressure is 888 PSI Test pressure is up to 1,500 PSI Relatively short duration (approx. 30 minutes) Reduce to intermediate pressure at 1,357 PSI Maintain for 8 hours 10

12 How the Test is Performed (con t) De-pressurize the line Drain the water from the system If 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 11

13 Safety During the Test Safety is our #1 priority Performed 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 12
