Natural Gas Highlights

• Columbia Gas received authorization to place into service its B System Project, which includes 22 miles of 

pipeline in Fairfield and Franklin Counties, OH. 

• Florida Gas received authorization to construct and operate its East-West Project, which would provide 275 

MMcf/d of capacity on its pipeline system in LA and TX to serve markets in the Texas Gulf Coast area.

• Texas Eastern and Brazoria Interconnector Gas Pipeline received authorization to construct the Stratton Ridge 

Expansion Project, which would provide 322 MMcf/d of firm transportation capacity from multiple receipt points on 

Texas Eastern to a delivery point on Brazoria's pipeline system in Brazoria County, TX. 

• CIG received authorization to abandon by sale to EPNG three interconnected pipeline segments that total 

approximately 40 miles, as well as certain metering and appurtenant facilities located at the interconnection of the 

CIG and EPNG pipeline systems in Moore and Potter Counties, TX.

• Northern received authorization to construct and operate its Marquette Branch Line Expansion Project, which 

would add 3,180 HP of new compression and 24.6 MMcf/d of additional firm capacity to supply two proposed 

electric generation plants in Upper Michigan.

• FGT received authorization to abandon 1.3 miles of 18-inch pipeline and appurtenances, which previously 

supplied the no-longer existing FPL's Cutler delivery point facilities in Miami-Dade County, FL. 

• Transco requests an amendment to its authorization to abandon by sale to Tana Exploration 21 miles of gathering 

pipeline located in offshore Texas. Transco seeks to abandon these assets in place, as Tana is no longer 

producing gas in that area and no longer needs these assets.

• Panther received authorization to abandon approximately 56 miles of gathering and transmission pipeline located 

offshore, and onshore in Jefferson County, TX.

• East Cheyenne received authorization to designate the West Peetz D Sands and Lewis Creek D Sands storage 

fields in Logan County, CO as a single, integrated reservoir, and to decrease the combined cushion capacity and 

increase the working gas capacity by 3.6 Bcf.

• Columbia Gas received authorization to construct and operate horizontal storage wells 12601 and 12602 and 

related pipelines and appurtenances at its Pavonia Storage Field. The new wells would be located in Ashland 

County, OH, and increase deliverability by 18 MMcf/d.

• National Fuel received authorization to abandon well lines CW-1407 and CW-1408 and convert two storage wells 

to observation wells at its Holland Storage Field in Erie County, NY.

• WBI Energy received authorization to abandon its Billy Creek Storage Field in Johnson County, WY.

• Transco requests authorization to construct its Southeastern Trail Project, which would provide an additional 296 

MMcf/d of firm capacity from Virginia to Louisiana. The project includes 7.72 miles of pipeline loop in Fauquier 

and Prince William Counties, VA, 60,720 HP of new compression, abandonment of some existing compression, 

and other modifications in GA, SC, and LA. 

• PNGTS requests authorization for its Portland X-Press Project, which would increase the certificated capacity on 

its system by 39.8 MMcf/d from Pittsburgh, NH to Westbrook, ME; and by 1.6 MMcf/d from Westbrook to Dracut, 

ME. In addition, it requests Section 3 authorization to increase its import/export capacity from 210 to 274 MMcf/d. 

• Transco requests authorization to abandon its North Padre Island Block 956 “B” Platform, and its offshore lateral 

extending 3.5 miles from North Padre Island Block 956 in Offshore Texas.

• El Paso requests authorization to construct its EPNG South Mainline Project, which consists of 17 miles of 

looping pipeline and new compression in Arizona, New Mexico, and Texas, that would deliver 321 MMcf/d of 

additional capacity to two customers in the Southwest.

• Southern Star requests authorization to construct 14.2 miles of non-contiguous segments of pipeline and abandon 

the equivalent segments in Oklahoma and Logan Counties, OK.

• Columbia Gas requests authorization to construct and operate Weaver Well 12622 and related pipeline and 

appurtenances at its Weaver Storage Field located in Ashland, Holmes, Knox, and Richland Counties, OH. 

• Dominion Energy Questar requests to amend its certificate in order to eliminate Operating Parameter 3, which 

would enable its customers to inject gas earlier than November 1 of each heating season at its Chalk Creek 

Aquifer Storage in Summit County, UT.
