11. North System remainder of the year
Item # 25-Southern will be conducting pipeline relocation on the North Main loop line east of our Tarrant compressor station July 13th to July 17th. We do not anticipate an impact to customers.
Item # 26-Southern will be conducting remediation on the North Main loop line west of our Tarrant compressor station August 17th to August 27th. We do not anticipate an impact to customers. P63
Item # 27-Southern will be conducting maintenance pigging on our Marietta Branch line east of our Bell Mills compressor station in northwest Georgia during the last half of the year. Customers may experience lower than normal pressures during the pigging.
Item # 28-Southern will be conducting a hydro-test on our 2ND North Main line east of our McConnells compressor station during the September/October time frame. Capacity could be reduced as much as 285 MMcf/d of the 590 MMcf/d available. IT and secondary firm could be impacted depending on demand requirements.
Item # 29-Southern will be conducting remediation on our 2nd North Main line west of our Tarrant compressor station during the September/October time frame. Capacity could be reduced as much as 355 MMcf/d of the 550 MMcf/d available. IT and secondary firm could be impacted depending on demand requirements. We will coordinate this work with the hydro test east of our McConnells compressor station item #28.

12. North System remainder of the year cont.
Item # 30-Southern will be conducting remediation on our 2nd North Main line east of our Tarrant compressor station October 5th through October 30th. Capacity could be reduced as much as 245 MMcf/d of the 550 MMcf/d available. IT and secondary firm could be impacted depending on demand requirements.
Item # 31-Southern will be conducting a relocation of our 12” Chattanooga Branch line in Catoosa County Georgia sometime during the last half of the year. We do not anticipate an impact to customers.
Item # 32-Fall Storage Field Shut-in tests - The Muldon Storage Field shut-in test will begin on Tuesday, October 6th and continue through Monday, October 12th. The Bear Creek Storage Field shut-in test will begin on Tuesday, October 20th and continue through Monday, October 26th.  
As a result of the shut-in test, Southern will reduce each CSS customer's DIQ and DWQ on a pro-rata basis. Each CSS customer will be allocated thirty- six percent (36%) of its currently effective DIQ and DWQ posted on SoNet Premier during the Muldon shut-in test and sixty-four percent (64%) during the Bear Creek shut-in test. This reduced level is subject to change, if necessary, during the test. Please be aware that this temporary reduction in DIQ and DWQ will affect not only CSS service, but also will affect related injection/withdrawal capacity under no-notice firm transportation (FT-NN) service

Item # 35-Southern will be conducting upgrade work at the Thomaston compressor station in central Georgia during the mid-August to October 30th timeframe. Capacity through Thomaston will be reduced as much as 330 MMcf/d of the 1.6 BCF/d available. IT and secondary firm will be impacted and firm services could be impacted depending on requirements east and north of the station. A study of this project is still ongoing to minimize the impact.
