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 West Bountiful, Centerville, Farmington, Kaysville and Layton. It runs from Porters Lane in West Bountiful north to Gentile Street in Layton. Some of this section was completed last year. (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 is scheduled to begin in January 2019 and continue through 2019.
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.

Project Updates
August 7, 2019
FL-122 Phase I
Centerville: We have a crew working near 1275 North. They are about to the Legacy Trail. A small section of Legacy Trail is currently closed. This crew has crossed 1275 North, with some restoration going on at that location. We have multiple crews working near Legacy Trail just north of 1275 North.
Legacy Trail closure: A small portion of Legacy Trail is now closed from 1275 North to Glovers Lane. We have trail-closure maps at each end of the closure if needed. We anticipate this closure will last three to four months, but that could change depending on weather and other circumstances. This re-route will be on the rail trail from 1275 North in Centerville to Glovers Lane in Farmington. This is a very simple detour that will keep traffic on the trail except for a small stretch on Glovers Lane.
FL-122 Phase II
Farmington: We have multiple crews accessing work areas off 650 West, working near Legacy Trail at the end of the dirt road south of the high school.
Legacy Trail closure: A small portion of legacy trail is now closed from 1275 North to Glovers Lane. We have trail-closure maps at each end of the closure. These are located at the trail-closure sign. We anticipate this closure will last three to four months, but that could change depending on weather and other circumstances. This re-route will divert to the rail trail from 1275 North in Centerville to Glovers Lane in Farmington. This is a very simple detour that will keep traffic on the trail except for a small stretch on Glovers Lane.
Kaysville: We have a restoration crew working on Deseret Drive. We have a crew at approximately 1900 South. We have restoration crews working on and off in these areas, as well as a crew working on our station at Kay Drive and Burton Lane. We have a crew at the corner of Brandon Drive and Deseret Drive. We have a crew on Deseret Drive and Old Mill Lane. We will have traffic control set up in this area. Please avoid this area if possible. We will have westbound-only traffic from 650 West to Deseret Drive on Old Mill Lane, and Deseret Drive will be completely closed from Old Mill Lane to Lodder Drive; look for detour routes.
We have traffic control set up from Main Street to 200 North on 400 West. We are currently planning to mill and pave Aug. 17-18.
We have a crew at about 125 North 400 West. They will continue south to Center Street to connect with the crew boring underneath I-15 and Center Street. They are still impacting Old Mill Lane from 600 West to I-15.
We have a crew near the railroad on Old Mill Lane preparing to bore underneath the railroad and UTA tracks, as well.
Layton: We have a crew working on Gentile Street just west of Wells Fargo. This is off the road and shouldn’t impact traffic other than trucks entering and exiting the work zone.

Construction Process
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.
Construction Zones
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 its buried and before its 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.
