Gas Feeder Line 122 Capacity Enhancement Project
Dominion Energy is replacing a section of its system in southern Davis County known as Feeder Line 122. (Feeder lines are larger, steel pipelines that supply smaller main and individual service lines that connect to meters at homes and businesses.) This webpage provides general information about the project as well as current information on construction activity and related impacts on local traffic.
Overview and Schedule
NEED for the project: The Feeder Line 122 Capacity Enhancement Project project is necessary to keep pace with increased demand for natural gas due to customer growth. It will also enhance our ability to continue providing safe, reliable natural gas service by making our system easier to monitor and maintain.
LOCATION: The section of FL122 slated for replacement is located in North Salt Lake, Woods Cross, West Bountiful, Centerville and Farmington. It runs from West Center Street and the Legacy Parkway near the Foxboro subdivision north to 500 South, then angles northeast between the Legacy Highway and Interstate 15 to West Porters Lane and then along North 640 West terminating at West Glovers Lane. (See map for exact route.)
CONSTRUCTION SCHEDULE: To expedite construction, multiple crews will be working simultaneously at various locations during the project. Crews may also work at night and on weekends. Allowing for weather and other demands, construction on the Legacy Parkway Trail section between West Center Street and 500 South is scheduled to begin Oct. 10, 2016, and is expected to be completed by May 2017. Construction on the remainder of the pipeline is scheduled to begin in January 2017.
To provide room for crews and equipment, some temporary lane restrictions and road closures can be expected in work zones. Every effort will be made to maintain access to businesses and driveways in construction zones at all times. No interruption to residents' natural gas service is anticipated during this project.
LEGACY PARKWAY TRAIL CLOSURE: To ensure public safety, during construction a section of the Legacy Parkway Trail between West Center Street and 500 South will be temporarily closed to all use. The temporary closure of the trail between the Center Street Trailhead and the 2425 South Trailhead is scheduled to begin Oct. 10, 2016. (See detour map.) The section from 2425 South and 500 South will be closed in January 2017. (See detour map.) Weather permitting, both sections of the trail will be reopened by the end of June 2017.

- Legacy Trail Update:
- Over the past several months, Questar Gas and its contractor Canyon Pipeline have been working to replace a section of natural gas pipeline that runs alongside Legacy Trail. New pipe has been installed from approximately Center Street in North Salt Lake to Mountain View Park in Woods Cross.
- With the pipe installed, we are now beginning the restoration process that has been delayed due to an extremely wet winter. The restoration will commence in two main sections: Center Street to 2425 South (Section 1) and 2425 South to 500 South (Section 2).
- Section 1 needs a lot of work before the trail can be restored. It requires a lot of rough grade work and drying out the soils before the subgrade work can begin for the trail. We are working on it as much as possible, but the ground is still wet from all the recent weather; each storm sets us back, having to wait for the ground to dry out.
- While the work in Section 1 proceeds, work in section 2 will be, too. Section 2 is in better shape, and will be easier to restore. Crews have begun to re-establish the trail between 2425 South and Mountain View Park by working on the subgrade to prepare it for new asphalt. Asphalt will be applied once the subgrade work is finished, putting us closer to reopening the trail.
- When crews are finished working on the trail north of Mountain View Park, they will begin working on the subgrade in preparation for asphalt. Once all the asphalt in section 2 is restored, the trail will reopen. Landscape work will continue after the trail is reopened, but will not affect traffic on the trail.
- After Section 2's asphalt is restored, crews will work on the asphalt in Section 1. As soon as Section 1 is asphalted, the trail will reopen. As with Section 2, landscape work will follow but won't affect use of the trail.
- We are focusing our efforts on Section 2 restoration first because it will shorten the detour route. Section 2 of the trail is now slated to open first part of July and Section 1 should open by the end of July.

Dominion Energy and our contractor, Canyon Pipeline of Phoenix, AZ, are committed to completing this project safely and on schedule while minimizing as much as possible any inconvenience to local businesses and residents. To accomplish this, some work may be performed at night and on weekends. This will reduce impacts on morning and evening commutes. We will adhere to all county noise-reduction ordinances. Canyon Pipeline has more than 40 years experience in 39 states building pipelines in urban settings.
For pipe buried beneath streets or highways, construction may require intermittent closures of one or more lanes of traffic. Driveways also may be occasionally blocked by excavation work, otherwise they will be plated to maintain access during business hours and at night and on weekends.
Before construction starts in front of any home or business, a representative will contact the owner or resident to discuss options for maintaining driveway access. Signs notifying the public that businesses remain open during construction are available.
To finish construction on schedule and as quickly as possible, the project is divided into sections, or "spreads." This allows multiple crews to work simultaneously at different locations. Work zones can range from a single intersection to several blocks long. At any one location the amount of time to cut pavement, install new pipe and replace asphalt can range from several days to several weeks.
The public can do its part to ensure construction proceeds safely and on time by finding alternative routes, driving carefully in construction zones and keeping children away from construction sites.
Dominion Energy works closely with city and state transportation officials to ensure safety and minimize inconvenience to drivers and pedestrians. However, for public safety it may be necessary to temporarily close streets and sidewalks or restrict vehicle and pedestrian traffic. As mentioned, driveways may occasionally be blocked by excavation work. We will make every effort to keep these inconveniences as brief as possible. Your patience is appreciated.
If you have questions or concerns, do not hesitate to contact us.
Steps During Construction
Following are brief descriptions of the steps involved in pipeline removal and construction:
- Locate buried utilities - The area below city streets can be a maze of underground utilities. To avoid damaging these facilities, a procedure known as potholing is used prior to trenching to identify the exact vertical and horizontal location of existing infrastructure, including the pipeline to be replaced..
- Move existing utilities - Before trenching (see next step), all water and natural gas service lines that cross the existing pipe will be moved to a lower depth. This will minimize the risk of interrupting water- or gas-service to individual homes or businesses once actual construction begins.
- Dig trench - After the pipe has been located and purged of gas and service lines in the trench zone moved, the pavement above the existing pipe is cut and removed. Then equipment is brought in to dig the trench. The depth of the natural gas pipeline trench will be determined by the location of the existing pipe and other utilities. As the trench is dug, the soil is loaded into trucks and hauled away for disposal in a designated landfill.
- Remove old pipe - Sections of pipe to be removed are cut into lengths, lifted from the trench, loaded onto trucks and hauled away for proper disposal.
- Deliver and "string" new pipe - New pipe is manufactured and inspected to ensure it meets industry and federal safety standards. Pipe sections are then delivered by truck to the construction site where they are placed end-to-end (or "strung") on skids adjacent to the trench. If necessary, a hydraulic machine bends pipe sections to fit around obstacles or conform to the direction of the trench.
- Weld new pipe together and coat - Welding crews join the sections of pipe together into a continuous length. Each welded joint is visually inspected, x-rayed and then coated for protection.
- Lower pipe into trench - Using one or more tractors, crews lift and then carefully lower the welded sections of pipe into the trench. Final welds are made to "tie-in" any unconnected sections.
- Backfill trench - Under streets, in place of the removed soil, a mixture known as "flowable fill" is used to backfill the trench. In other areas, the original soil is replaced.
- Pressure test new pipe - After it's buried and before it's put into service, the entire length of new pipe is hydrostatically tested to ensure the integrity of the system. This is done by filling the pipe with water, pressurizing the system above its maximum operating conditions and holding the pressure for a specified time. The pipe is drained, cleaned and dried before put into service.
- Clean-up and restore ROW - The final step is to repair the surface over the trench. If necessary, fences or sod may also be replaced.
- Directional bore - At some busy intersections, most water crossings and under major roads, instead of trenching, crews will install pipe by boring horizontally underneath the road, stream or canal. The boring machine drills a hole from one side of the road or stream. Pipe is strung on the other side and then pulled back through hole.

Frequently Asked Questions
Why is this project necessary?
At Dominion Energy, we are committed to providing safe, reliable natural gas service at the lowest possible cost.
In recent years, as part of our continuing efforts to meet growing demand for natural gas while improving overall system integrity, we have begun replacing vital sections of our underground pipeline system serving the Wasatch Front. In most cases we are replacing older pipe with newer, stronger and larger diameter pipe.
These new pipelines carry more supplies, enabling us to better serve the growing number of new homes and businesses in Utah.
They also enhance safety and reliability by making our system easier to monitor and maintain. Some of the older sections of our system have pipe in varying diameters, ranging from six to 20 inches. Replacing these with pipe of the same diameter makes them accessible to "smart tools. These tools -- commonly known as "pigs" -- use MRI technology to inspect the pipe interior, making it possible to detect and correct potential problems before they occur.
Will my natural gas service be affected by construction?
No. Redundancies in our system should make it possible to replace the existing pipeline without interrupting service to any customers.
Will construction affect my property?
If your property is on or adjacent to the right-of-way, you will receive prior notification by mail alerting you to construction. We work closely with residents and city officials to minimize potential impacts on residents' property. If we do need to access its legal right-of-way to work on or near your property, the company will make reasonable efforts to ensure the landscape is returned as closely as possible to its previous state. This does not include replacement, repair or compensation for unauthorized structures, plants, objects and etc. currently located within the right-of-way.
Residents can make the process easier by making sure that items such as large, deep-rooted trees, concrete slabs, sheds, fences or other structures do not encroach upon our right-of-way. These items not only violate right-of-way policy but also pose a safety hazard and may hinder our ability to reach our pipeline in case of emergency or to perform necessary maintenance.
For more information about what is and is not allowed on pipeline rights-of-way, request a company brochure by contacting a representative at (801) 324-3149 or view our brochure.
Will streets be closed or access to private driveways restricted during construction?
Construction may require temporary lane closures and/or detours. During construction, we strive to maintain traffic in both directions on city streets at all times, however temporary lane restrictions can be expected.
Private driveways and access to side streets and business parking lots may also occasionally be temporarily blocked by excavation work. When not in use, open trenches will be plated to maintain access during business hours, at night and on weekends.
Any changes in traffic or access will be kept to a minimum and will be as brief as possible.
Before construction starts in front of your home or business, a company representative will contact you to discuss where you would like access maintained. Signs notifying the public that businesses are open during construction will be made available for those who request them.
For the latest information on traffic impacts and lane restrictions, visit this site or email us to receive weekly construction updates by email.
Residents can reduce the risk of accidents by driving carefully in construction zones and keeping children away from the construction site. We work closely with city and state transportation officials to ensure safety and minimize inconvenience to drivers and pedestrians during construction.
