PROJECT OVERVIEWThe proposed Atlantic Sunrise Expansion Project would include expanding the existing Transco transmission pipeline by adding new pipeline infrastructure in Pennsylvania, as well as modifying some existing Transco facilities in Pennsylvania and other states (Maryland, Virginia, North Carolina, South Carolina), to allow gas to flow from north to south.

The project design includes approximately 185 miles of new greenfield pipe (Central Penn Line), two new pipeline segments (loops) located along the existing Transco pipeline that total about 15 miles (Chapman Loop and Unity Loop), 2.5 miles of existing pipeline replacement, two new compressor facilities in Pennsylvania and other facility additions or modifications in five states.

INFRASTRUCTURE NEEDPennsylvania is the fastest-growing natural gas-producing state. But it has been well-documented that insufficient pipeline capacity limits and constrains access to abundant Pennsylvania natural gas supplies. Without vital energy infrastructure to move gas to market, prices will continue to hinder activity, investment and job creation in Pennsylvania’s shale-producing regions.

Atlantic Sunrise will create consumer access to an abundant supply of clean, affordable energy, further reducing energy costs for consumers. Additionally, the project is designed to supply enough natural gas to meet the daily needs of more than 7 million American homes, helping to accelerate America’s track to energy independence.

ECONOMIC IMPACTAt Williams, we are working to expand our existing Transco energy infrastructure through a $3 billion private investment called Atlantic Sunrise. This critical pipeline project, an approximately 185-mile expansion, will connect abundant, affordable Pennsylvania gas supply with consumers in growing energy markets all along the East Coast. In the process, this project will generate approximately $1.6 billion in additional wages, revenues and investments across the state, supporting approximately 8,000 direct and indirect jobs.

Williams has calculated the economic impacts at the local level. To determine what the impacts will be in a specific municipality or county, click here.

REGULATORY STATUSWilliams filed a formal application with the Federal Energy Regulatory Commission (FERC) for the Atlantic Sunrise project in March 2015 (Docket No. CP15-138). FERC issued its draft environmental impact statement (DEIS) for the project in May 2016, concluding that environmental impacts would be reduced to “less than significant levels” with the implementation of mitigation measures proposed by the company and FERC. Public comment meetings related to the DEIS were held from June 13-16, 2016. FERC established Oct. 21, 2016, as the deadline for issuance of the final EIS and Jan. 19, 2017, as the 90-day federal authorization deadline (for other federal agencies to issue their permits).

The construction of Atlantic Sunrise also requires permits from the Pennsylvania Department of Environmental Protection (DEP), including Chapter 102 and 105 permits. Due to the scope of the project, the PA DEP held a public comment period for these two permit applications.

COLLABORATIVE APPROACHWilliams has made adjustments to more than half of the pipeline route to address concerns identified by landowners, communities and permitting agencies. This includes more than 400 modifications to the 180-mile greenfield route. Williams also has voluntarily agreed to fund more than $2.5 million in environmental conservation projects through a unique partnership with The Conservation Fund. These projects will restore more than 10 miles of wildlife habitat along streams, prevent thousands of pounds of harmful nutrients from entering waterways and support the construction of eight miles of new trails in central and southeastern Pennsylvania.

CONSTRUCTION PROCESSDuring the construction phase of the Atlantic Sunrise pipeline project, approximately 8,000 jobs will be created, adding $870 million in economic value to the commonwealth.

Once operational, Atlantic Sunrise pipeline will help millions of American homes and businesses gain access to affordable, reliable, environmentally responsible and domestically produced natural gas.

A pipeline construction project looks much like a moving assembly line. A large project typically is broken into manageable lengths called “spreads,” and it uses highly specialized and qualified work groups. Each spread is composed of various crews, each with its own responsibilities. As one crew completes its work, the next crew moves into position to complete its piece of the construction process.

ATLANTIC SUNRISE

THE CONSTRUCTION PROCESS IS BROKEN DOWN INTO TASKS, WHICH INCLUDE: Preconstruction survey

Before construction begins, crews survey environmental features along proposed pipeline segments. Utility lines and agricultural drainages are located and marked to prevent accidental damage during pipeline construction. Last, the pipeline’s right of way (ROW) boundaries are staked.

Clearing and grading

The pipeline right of way is cleared of vegetation. Temporary erosion control measures are installed before any earth- moving activities.

Trenching

Topsoil is removed from the work area and stockpiled separately in agricultural areas. Crews will use backhoes or trenching machines to excavate a pipeline trench. Soil is segregated and stockpiled away from the trench, pipe assembly areas and traffic zones.

Pipe stringing

Individual joints of pipe are strung along the right of way adjacent to the excavated ditch and arranged so they are accessible to construction personnel. A mechanical pipe-bending machine bends individual joints of pipe to the desired angle

at locations where there are significant changes in the natural ground contours or where the pipeline route changes direction.

Welding and coating pipe

After the stringing and bending are complete, the pipe sections are aligned, welded together and placed on temporary supports along the edge of the trench. All welds are then visually and radiographically inspected. Line pipe, normally mill-coated or yard-coated before stringing, requires a coating at the welded joints. The entire pipeline is then electronically inspected to locate and repair any coating faults or voids.

Lowering pipe in, backfilling and testing

The pipe assembly is lowered into the trench by side-boom tractors, and the trench is then backfilled. Once in place, the pipeline is hydrostatically tested following strict federal regulations.

Restoration

As soon as backfill operations are complete, crews will commence cleanup and restoration activities, including completion of final grading and topsoil replacement. The construction right of way will be graded to restore preconstruction contours. The environmental inspector will see that the contours and topsoil are returned to their original condition.

FREQUENTLY ASKED QUESTIONS

ATLANTIC SUNRISE

SAFETYWhat will you do to make sure this pipeline project is constructed properly?

Williams is a nearly 110-year-old energy company which has safely and reliably operated in Pennsylvania for more than 65 years. Williams historically has a strong safety record, and we remain above the industry safety average.

For Atlantic Sunrise, we are demonstrating our commitment to safety by exceeding federal safety regulations in a number of critical areas, including:

• Pipe material to meet and generally exceed the API-5L requirements

• Using a 0.5 design factor for all fabricated MLV assemblies

• Class 2 pipe to be installed in all Class 1 locations to increase the safety factor

• 100 percent nondestructive inspection of mainline welds (for example, 49 CFR 192 requires only 10 percent of the welds to the be tested in Class 1 locations)

• Providing additional cover depth at certain locations (36 inches in Class 1 locations where only 30 inches of cover is required and 60 inches of cover under ditches of all public roads and railroad crossings where only 36 inches is required)

• Hydrostatically testing the pipe at a maximum pressure that will exceed industry standards identified in 49 CFR 192 (1.5 times the maximum allowable operating pressure) before placing the line into service

How safe are pipelines?

According to U.S. Department of Transportation (USDOT) statistics, pipelines are the safest method for transporting energy – in fact, pipelines have a success rate of 99.9 percent. As this project is designed, constructed and operated, Williams is committed to maintaining the highest standards of safety, using construction and operational procedures that exceed already stringent industry regulations.

Once operational, the new pipeline will be maintained and operated according to procedures outlined in our Pipeline Integrity Management Program. These procedures, many of which exceed federal industry regulations, include monitoring of the pipeline 24 hours a day, seven days a week.

Who has oversight over interstate pipelines?

The USDOT Pipeline and Hazardous Materials Safety Administration (PHMSA), Office of Pipeline Safety (OPS) and their partnering state regulatory agencies inspect transmission pipelines and enforce the regulations to better ensure safety and reduce risk. In addition to federal government regulatory requirements, standards and recommended practices are developed by industry organizations, such as the American Petroleum Institute, to provide further guidance on the safe construction, operation and maintenance of pipelines.

REGULATORYWhat conclusion did FERC reach in its DEIS?

The Federal Energy Regulatory Commission (FERC) draft environmental impact statement (DEIS), issued in May 2016, concluded that environmental impacts would be reduced to “less than significant levels” with the implementation of mitigation measures proposed by the company and FERC. The DEIS contained additional mitigation measures the company must follow, as well as other minor route alternative recommendations.

Who decides if the pipeline gets built?

Interstate natural gas pipelines are regulated by the FERC. The Commission requires operators like Williams to obtain a federal Certificate of Public Convenience and Necessity – in addition to various state permits – before any pipeline facilities can be built.

How long does the regulatory process take?

The time required for federal review and pipeline construction varies depending on the size of the pipeline project. For the Atlantic Sunrise Project, Williams filed an application with FERC on March 31, 2015. If the application is approved by FERC, Williams could begin construction in early 2017.

Can I see all the information provided to FERC for the ASR pipeline?

The FERC application process has been designed with transparency as its cornerstone. All information provided to FERC by the applicant is part of the public record and available for public inspection. The only information that is not viewable by the public is data that have been designated by FERC as sensitive for national security or privacy reasons. You can search for info on the FERC website by referencing the project’s docket number: CP15-138.

PROJECTHow much of the route has changed since the project was introduced?

Williams has made adjustments to more than 50 percent of the original route to address concerns identified by landowners, public officials and permitting agencies.

Williams has already incorporated more than 400 route variations into the proposed route to address stakeholder concerns – and we are still making adjustments. As recently as May 18, 2016, we made a supplemental filing with FERC, which included the adoption of 39 additional minor route adjustments in response to landowner requests.

Who are your customers?

Our customers are a mix of nine natural gas producers, local distribution companies and power generators located in the Mid-Atlantic and Southeast United States.

It is important to note that even though your local distribution company may not be an Atlantic Sunrise customer, it can still contract directly with a Marcellus producer to receive gas supply via Atlantic Sunrise.

How do you expect this project to affect the price of natural gas?

This project will provide customers in the Mid-Atlantic and Southeast United States with access to economically priced natural gas originating from the largest gas supply region in the country.

Because of a lack of pipeline infrastructure, during times of peak demand some Transco customers pay up to 25 times more than the price of gas traded on the spot market in Pennsylvania.

Why is the Atlantic Sunrise expansion needed?

Williams’ Transco pipeline network transports 10 percent of the natural gas consumed in the U.S. For decades the majority of that gas originated in the Gulf of Mexico, but today an increasing amount of that gas is coming from Pennsylvania.

Once the Atlantic Sunrise project is placed into service, it will extend the reach of our existing Transco infrastructure so that natural gas consumers all along the East Coast (local distribution companies, manufacturers, power plants, etc.) will have direct access to Marcellus supply originating in northeast Pennsylvania. This is highly sought after because natural gas sourced from this Marcellus supply area trades at a lower cost than natural gas originating from other basins (such as the Gulf of Mexico and Canada).

ENVIRONMENTALWhat impact will the project have on wildlife?

From the draft environmental impact statement: “Given the impact avoidance, minimization and mitigation measures proposed by Transco, as well as our recommendations, we conclude that the construction and operation of the Project would not have a significant adverse effect on wildlife, including migratory birds.”

Williams has obtained project clearances for wildlife impacts from the Pennsylvania Department of Conservation and Natural Resources, the Pennsylvania Fish and Boat Commission and the Pennsylvania Game Commission (reroutes are pending approval).

How would construction of the project impact wetlands?

No permanent wetland loss would result from the implementation of the project.

Construction of the pipeline facilities associated with the Project would affect a total of 50.4 acres of wetlands. Eighty-eight percent of those impacts (44.0 acres) would be considered temporary.

Williams will conduct routine monitoring of all wetlands affected by construction until revegetation is successful and will implement mitigation measures to control invasive species as described in its environmental construction plan.

From the draft environmental impact statement: “Based on the avoidance and minimization measures developed by Transco, as well as our recommendation, we conclude that impacts on wetland resources would be effectively minimized or mitigated.”

Will landowners be able to farm the land after pipe installation?

Yes. After construction of the pipeline, most uses of the surface of the land will be allowed, including farming activities such as crop production and raising livestock. Two notable exceptions include planting trees within the easement and placing a permanent structure within the easement, both of which are prohibited.

How is Williams working to minimize impacts to agricultural areas?

Williams has developed a draft agricultural construction and monitoring plan for the project, which documents the measures it would follow to minimize and mitigate effects on agricultural lands. In addition, Williams has proposed to provide an agricultural inspector who would be on-site to monitor construction activities within agricultural lands and would hire a subject matter expert to provide guidance to ensure these lands are restored to their original uses and crop yields. The draft agricultural construction and monitoring plan includes mitigation measures to minimize impacts on and/or meet the needs of specialty agricultural crop areas (i.e., orchards and tree farms), certified organic farms and no-till farms.

How will the project cross water bodies?

Crossing of water bodies will be conducted in accordance with state and federal permits, and with project-specific procedures. Williams will use various methods for installation of the pipeline across water bodies, depending on classifications and flow conditions at the time of crossing. This will include using trenchless construction methods to avoid impacting environmentally sensitive areas. The company has coordinated with federal and state agencies throughout the regulatory process to develop appropriate crossing methodologies for all water bodies.

Williams is proposing to use trenchless crossing methods (conventional bore or HDD) for eight of the water body crossings, including both Susquehanna River crossings and the Conestoga River. Implementation of the mitigation measures outlined in Williams’ environmental construction plan and other project-specific plans would help avoid or minimize temporary impacts on surface-water resources.

What precautions will be taken to prevent the subsoil from mixing with the topsoil?

On improved lands, topsoil will be excavated and segregated into separate stockpiles to allow for the re-establishment of the original soil profile. In agricultural fields, hayfields and other fields used for crops, the top 12 inches of topsoil will be segregated into a separate stockpile. In places that have less than 12 inches, all of the topsoil will be removed and stored separately. Once construction is complete, the subsoil will be placed into the trench first, followed by the topsoil.

LAND USE AND EASEMENTSWhat is an easement?

An easement is a limited right to use the land for specific purposes. If Williams needs to acquire a new easement, we will compensate the landowner for the right to construct, operate and maintain an underground pipeline (and, in limited cases, aboveground equipment related to the pipeline, such as valves).

What size will the easement be?

The amount of land required for the easement will vary on each tract of land depending on a number of factors. A Williams land agent will discuss the land requirements with the landowner during the easement negotiations.

In areas where there is no existing Transco pipeline easement, the width of the new permanent right of way will be limited to 50 feet. If there is an existing easement on the property, we will typically need an additional 25 feet of permanent easement for operation and maintenance of the new pipeline.

Will landowners still own the land, and can they still use the land?

It is important to note that an easement does not transfer title of the land to Williams; it merely grants the right to use the land for the specific purposes stated in the easement agreement. After construction of the pipeline, most uses of the surface of the land – including farming activities such as crop production and raising livestock – will be permitted.

Landowners may return to normal surface uses of the land with limited restrictions. However, any digging – even for fencing, vegetation or drainage – is prohibited without first contacting the local One Call system (simply dial 811) or a Williams representative. No trees may be planted on the right of way or the placement of a permanent structure. This is to maintain a clear aerial surveillance of the right of way, and to prevent tree roots from damaging the pipeline coating.

LAND USE AND EASEMENTS CONTINUED

What is the width of the survey area, and why is surveying necessary?

The width of the survey corridor is approximately 600 feet. This width provides us greater flexibility when making final routing decisions.

Ground surveys are a first step in gathering critical information for developing a pipeline proposal. Generally, each property will be visited by specialists in land, engineering and environmental sciences. Some properties may need to be revisited to obtain additional data.

After the survey teams are finished, landowners may see survey stakes or ribbon tied to fences or vegetation. These markers are necessary to maintain a line of sight for the areas that have been surveyed. Survey crews will take every precaution to ensure no damage to property or disruption of daily activities will occur.

How much construction workspace is needed?

The total width of the construction work space will vary depending on such factors as slope, soil conditions and regulatory requirements. Generally, approximately 80 to 125 feet of work space will be required to construct the pipeline. All temporary work space will revert to the landowner upon completion of construction, with no restrictions.
