After an extensive review, the Federal Energy Regulatory Commission (FERC) has approved a proposal to significantly expand the capacity of the

Transco pipeline in Alabama, beginning in May 2017.

We are providing this newsletter to parties who may be affected or have an interest in the pipeline proposal.

The Hillabee expansion project will involve the construction of approximately 43 miles of pipe segments (called loops) parallel to the existing Transco pipeline in Alabama, in addition to adding compression and modifying some existing pipeline facilities. Constructed in three separate phases over a four-year period, the project is designed to supply gas to the proposed Sabal Trail pipeline.

The project will ultimately involve the construction of six pipe loops located in parts of Choctaw, Autauga, Chilton, Coosa and Tallapoosa counties (see map on page 3 of this newsletter). The pipeline loops vary in length and are proposed to parallel the existing Transco pipeline, either completely within or adjacent to the existing utility corridor.

In addition, as part of the proposal Williams plans to construct and operate a pipeline compressor facility in Choctaw County. Phase I pipeline construction is tentatively scheduled to begin as early as June 2016, while compressor station construction is targeted to begin in April 2016.

Since November 2013 the company has been involved in the FERC pre-filing process, soliciting input from citizens, governmental entities and numerous other

interested parties to identify and address issues with potential facility locations. The proposal approved by FERC reflects some adjustments to the original pipeline alignment introduced more than two years ago —most a direct result of stakeholder input.

“This FERC approval is a milestone and the culmination of a tremendous collaborative effort. We are very grateful for all of those who participated in this process. We also sincerely appreciate the cooperation we have received from property owners, permitting agencies and other interested parties whose assistance has helped bring us where we are today,” said A.J. Patel, Williams project manager.

“As we enter the construction phase of this project, we are committed to working with affected communities and property owners to ensure these new facilities are constructed in a prompt, safe and environmentally sensitive manner,” added Patel.

Prior to receiving federal approval, the FERC issued an Environmental Impact Statement (EIS) in December 2015. The EIS is a comprehensive assessment of the environmental effects of the pipeline project. The EIS concluded that the construction and operation of the proposed facilities, with the adoption of recommended mitigation measures, would not significantly affect the environment.

If your property is affected by construction, you can expect to be contacted by a Transco land representative prior to construction to share more details about the construction process. Transco land representatives are available before, during and after construction to answer any questions you may have.

The Transco pipeline is a 10,200-mile pipeline system which transports natural gas to markets throughout the northeastern and southeastern United States. It transports about 10 percent of the nation’s natural gas.

Frequently Asked Questions About the Hillabee ProjectHow long will pipe loop construction last?

Phase I pipeline construction would occur between June and December 2016, although the majority of work in any one area would typically be completed in six to eight weeks. Tree clearing could begin as early as July 2016. Williams would finish and place Phase I of the project into service in May 2017.

What are your typical construction work hours?

Standard construction operating hours are 7 a.m. to 7 p.m., Monday through Saturday, but may vary to be in compliance with local ordinances This daily schedule allows optimal use of daylight hours and offers safer construction conditions during peak construction season.

How will you construct around septic systems?

Williams’ land agents will handle septic system issues as they arise on a case-by-case basis and in a timely manner, as this is a very important issue for landowners. If the pipeline’s new proposed right-of-way impacts an existing septic system, then the company will take responsibility for having it repaired, or replaced/relocated off the right of way, with the landowner’s permission (assuming that there is room).

What will the company do to protect water wells?

Williams’ land agents will solicit input from each affected landowner about the number and location of water wells that are present on their property. Prior to construction, Williams will seek landowner permission to test all wells within 150 feet of the construction footprint before and after construction. Any problems with tested water wells after construction begins will be promptly resolved by the company.

Is construction vibration something that is monitored?

Williams offers vibration monitoring for home structures for interested landowners. This would consist of both pre-construction and post-construction structural analysis of foundations and structures by a professional structural engineering firm.

Will topsoil be segregated from subsoil?

Topsoil will be segregated (removed and stored in a pile or on the right of way along the edge of the construction right of way) in residential areas at the beginning of construction and then the topsoil will be replaced after the pipe is installed. The subsoil, which receives the bulk of the construction traffic, will be tested and decompacted as necessary by the contractor with a disc/harrow or chisel plow. In Williams’ experience, soils within the right of way (footprint) don’t typically exhibit percolation problems.

What happens if I have livestock on property where new pipeline is planned?

In general, livestock concerns are addressed with each individual landowner. Some things that the company will do to work with landowners are erecting temporary fencing, providing access points for livestock and/or farm equipment and vehicles to move across the construction area and/or compensating the landowner for additional feed, hay or off-site boarding of livestock during construction. After construction, all permanent fencing will be replaced with the same materials and in the same location as prior to construction. Other accommodations may be made based on specific situations and landowner input.

Are there any local benefits?

Once the pipeline becomes fully operational, the preliminary anticipated ad valorum tax benefit is anticipated to be approximately:

■ Autauga County – $500,000

■ Chilton County – $200,000

■ Choctaw County – $1,500,000

■ Coosa County – $1,100,000

■ Dallas County – $700,000

■ Tallapoosa County – $400,000
