Central Corridor Gas Pipeline Extension Project

Natural Gas Pipeline Construction Project

This project is part of a larger project designed to improve, protect and expand our system for current and future customers. This pipeline extension project will enhance gas supply reliability and flexibility across the system, replace and modernize aging infrastructure and enable Duke Energy to supply natural gas in southwest Ohio.

Project Information

  • The two routes proposed to the Ohio Power Siting Board (OPSB) are located in Hamilton County. The preferred route is shown in orange on the map, and the alternate route is shown in green.
    On the northern end, both connect to an existing line (C314) at the same location near the border with Butler and Warren Counties. On the southern end, the two proposed routes connect to an existing line that travels between the Norwood and Fairfax areas. The preferred route connects in Fairfax, and the alternate route connects in Norwood.
  • Summer 2017: Begin easement negotiations.

    Fall 2017: Receive OPSB permit and bid construction.

    Winter/Spring 2018: Start construction.

    Fall 2019: Complete construction and put pipeline in operation.

    Spring 2020: Complete restoration.

  • The Central Corridor Pipeline Project is part of our large-scale Plan to Improve, Protect and Expand our System (PIPES) designed with three main goals:

    1. Improve, protect and expand our system for current and future customers.
    2. Enhance gas supply reliability and flexibility across the system.
    3. Replace and modernize aging infrastructure.
  • The pipeline project was developed from a long-range plan that was completed in 2015. This study includes a review of retiring and replacing aging infrastructure, increasing customer demand, and improving reliability over the next 20 years.
  • 20-inch-diameter steel pipe with an epoxy coating to prevent rust.
  • It will measure 20 inches in diameter, be installed in welded 40-foot sections and run approximately 14 miles.
  • A minimum of four feet below ground, which will be below the Cincinnati region's 32-inch frost line, as defined in the Ohio Building Code. The minimum depths will be increased as necessary to protect the pipe from outside load influences.
  • This pipeline will provide natural gas service to our customers in southwest Ohio. Our integrated natural gas delivery system, located in Ohio and Kentucky, typically moves gas from Duke Energy Kentucky's service territory in northern Kentucky to Duke Energy Ohio's service territory in southwest Ohio. However, natural gas can occasionally flow in the opposite direction. 

    Duke Energy has no intention of transporting natural gas outside of its integrated delivery system.
  • The proposed pipeline will have a normal operating pressure of approximately 400 psi and a maximum allowable operating pressure (MAOP) of 500 psi.
  • The pipeline will be designed, installed and monitored to last for 75-100 years, during which time natural gas is expected to remain an important part of the energy supply mix for the Greater Cincinnati Region. Specific timelines on replacing infrastructure depends on many factors that can only be determined by monitoring and inspecting the pipeline.
  • Two propane peaking plants need to be retired, and existing lines do not have the capacity to supply enough gas to accomplish the goal of retiring these plants. These plants provide more than 10 percent of the system load on a peak day.

    Duke Energy also has seen a significant increase in natural gas demand from commercial and industrial customers switching from other fuels (coal, fuel oil and propane). Industrial customers converting to natural gas have added natural gas usage equivalent to 75,000 homes.
  • A smaller diameter pipe would require higher operating pressures to supply the same volume of gas. Duke Energy also will use the pipeline to maintain proper operating pressures relative to our provision of natural gas service to our customers in southwest Ohio.
  • Duke Energy considered several construction options and believes constructing one pipeline is best. One of the driving factors behind this decision is the company's commitment to minimize impact to the community, and multiple pipeline alignments would impact many more properties.
  • We work to help customers reduce natural gas consumption in multiple ways, but efforts to reduce natural gas consumption are not enough to meet the growing natural gas demand in southwest Ohio.
  • Our system currently has two propane peaking plants more than 50 years old that will be retired in the near future as part of our long-range plan. Propane peaking plant technology is a method of supply, and rebuilding the plants would not address balance of supply issues, aid in the replacement of aging infrastructure, or address concerns related to storing and handling liquid propane. Furthermore, the presence of propane in the natural gas system is challenging for some customers, including natural gas vehicle (NGV) filling stations.
  • Without this pipeline project, Duke Energy Ohio may not be able to supply gas to our customers on peak days (when the demand for natural gas is higher) after the propane plants are retired.
  • The new line will provide flexibility in our system by making existing service less reliant on the southern supply of gas that currently flows north on our natural gas system. 

    Currently, if there are issues with the lines south of our service territory impacting natural gas supply coming into our Duke Energy distribution system, we would be challenged to provide gas services to all our customers. 

    This new line would provide reliable gas availability in the event of such issues by allowing us to reconfigure our system to provide gas from multiple providers in multiple areas of our system.
  • Duke Energy tracks the number of customer outages as a way to measure the reliability of the gas pipeline system. Its goal is zero outages related to controllable (internal) issues.
  • Solar, wind, and hydro energy sources generate electricity and do not help meet the growing demand for natural gas.
  • Duke Energy has made every possible effort to contact those persons and entities who may be potentially affected, as defined by the OPSB. That includes owners, tenants, and other residents of parcels that are crossed by a possible route or that are contiguous to a crossed parcel. 

    We followed OPSB guidelines to inform property owners along the original three proposed routes once routing analysis was completed and pipeline corridors were established by sending notifications to the affected property owners, posting notices in the local newspaper and providing a project web-page.

    The public has had – and will continue to have – the opportunity to provide input through the OPSB process.
  • In February 2016, Duke Energy Ohio initiated communication and met with community leaders along possible routes.

    We have continued communication with these community leaders through dozens of meetings. We have a long history of working cooperatively with the communities in which we operate and remain committed to that relationship in respect to this project.
  • Depending on which route is chosen, we believe the cost will be between $100 million and $150 million.
  • Duke Energy is funding the project without any specific tax abatements, subsidies, grants, or other government funds.
  • Given that costs associated with such infrastructure investment are ultimately passed through to customers, it is critical the company look at constructing such infrastructure in a fiscally responsible way.

    To keep costs manageable, thousands of pipeline corridors were investigated to determine the optimal routes.
  • The C314 line to the north is 10 miles long, 24 inches in diameter and has a normal operating pressure of 600 psi. This line travels through a variety of areas, including residential and commercial sections, from the Mason area to just south of the Hamilton, Butler, and Warren County intersection, where the Central Corridor Pipeline will connect.

  • Because a portion of this route is in a densely populated area, the pipe will be designed to a class four location. This means the attributes of the pipe will be more stringent than in more rural areas. The grade of steel will be stronger, the wall thickness will increase, or a combination of both will be specified. 

    An epoxy coating will be applied to protect the pipe from corrosion. In addition, pipelines involved in horizontal directional bores will have an additional coating called POWERCRETE® to help protect against abrasions when pulling the pipe through the bore hole.
  • Remote control shut-off valves will be installed to help isolate individual pipeline segments and to reconfigure the system to maintain its integrity. All pipeline segments will be located within 2.5 miles of a remote control shut-off valve. Our central gas control team monitors pressures 24/7 at various locations on the natural gas network to ensure the integrity of the natural gas system. This team of experts is trained annually to handle abnormal operating conditions that may arise.
  • A cathodic protection system is used to ensure the metal does not deteriorate from corrosion over time and to maintain the integrity of the pipe. Part of the cathodic protection system is the coating and the other is a process called cathodic protection, which mitigates the corrosive effects of the environment in which the pipeline exist. Anodes are placed at strategic locations on the pipe to provide cathodic protection which will mitigate the effects of corrosion.
  • The proposed pipeline will have a normal operating pressure of approximately 400 psi and a maximum allowable operating pressure (MAOP) of 500 psi. Duke Energy is only pressuring the pipe to less than 20% of its designed and manufactured maximum capacity.
  • Duke Energy does not calculate a "danger area," as such. There is no governmental definition of this term. However, the Code of Federal Regulations does define a Potential Impact Radius (PIR) for the purpose of integrity management. The distance determined as the PIR is based on the pressure in the pipeline, the diameter of the pipeline, and a factor that addresses the type of gas being transported. The PIR for this pipeline is 326 feet on either side of the center of the pipeline.
  • We will install yellow-capped gas markers along the route so that the pipeline path can be seen. Contractors are also required by law to call 811, "Call Before You Dig," to have underground utilities marked in advance.
  • The work area will be fenced off to ensure safety. If you notice the fencing has been tampered with, notify Duke Energy immediately.
  • All gas within the Duke Energy system is odorized to help detect leaks. If you smell natural gas, which is often described as a rotten egg smell, there could be a gas leak. You should leave the area, go to a safe place, immediately call 911, and call us at 800.634.4300.

    If you notice any land erosion along the right-of-way or excavation that does not appear to have an Ohio Utilities Protection Services (OUPS) indication of the line (the paint on the grass or pavement), call Duke Energy at 800.634.4300. We will respond with a crew at your home in a short period of time.
  • Numerous pipelines already exist in southwest Ohio, for which the community emergency response organizations are prepared to respond. We attend the Hamilton County Fire Chiefs Association Meetings regularly. This topic has been addressed, and we will coordinate an effort with the fire chiefs to adequately engage the government officials and work with them on planning scenarios. Duke Energy also provides grant opportunities for fire departments.
  • At this point in the process, it is too early to advise local responders as the final route has not been selected.
  • Any incident or safety-related condition, as defined by the Pipeline and Hazardous Material Safety Administration (PHMSA), undergoes an extensive investigation to determine the root cause of the incident. Lessons learned are included in that investigation and Duke Energy works collaboratively with PHMSA and/or the Public Utilities Commission of Ohio to develop additional actions that we must take to prevent that type of incident from occurring again.
  • The gas purchased from interstate pipelines is monitored by gas analyzers at gate stations for H2S, O2, H2O, and CO2 (molecules that can contribute to corrosion) before entering our distribution system. If the analyzer readings exceed limits, alerts are received. 

    Duke Energy Ohio also completed an Internal Corrosion Direct Assessment (ICDA) Program in 2007 and 2014 on its system and found no evidence of internal corrosion. 
  • The Transmission Integrity Management Program regulations require risk analysis. Duke Energy is expected to consider all information that can affect the likelihood and consequences of pipeline failure, including weather-related and outside-force threats. Topography, soil conditions, and earthquake faults all are among the data to be integrated. Thus, if such external risk factors are significant, they must be considered.
  • Strengthening its gas system by replacing and retiring aging infrastructure reduces risk and provides a dependable, flexible gas system for future generations in southwest Ohio.

    The two propane peaking plants are specific examples of aging infrastructure that need to be retired. On the coldest days of the year, these plants currently provide more than 10% of the system load on a peak day. 

    After the propane plants are retired, Duke Energy will not be able to supply gas to all of its customers on a peak day without this pipeline project. The pipeline will be designed, constructed, tested and monitored to reduce or eliminate known risks associated with the installation and operation of a natural gas pipeline.
  • Duke Energy is proposing to construct and operate this pipeline following industry best management practices and in full compliance with modern engineering safety and regulatory controls. The US Department of Transportation Pipeline and Hazardous Materials Safety Administration (PHMSA) has jurisdiction over pipeline safety. It has delegated the responsibility for supervising inspections in Ohio to the Public Utilities Commission of Ohio. Duke Energy, therefore, is subject to regulation at both the federal and state levels.
  • PHMSA's current Transmission Integrity Management Program regulations, established in 2004, require operators to identify threats, rank risks and implement integrity management assessments to maintain structural integrity and safety of the transmission lines in High Consequence Areas (HCAs). 

    HCAs include areas such as residential neighborhoods, apartments, schools, hospitals, shopping centers, businesses, retirement communities, ballparks and parks. It is important to note that, even though only segments of the pipeline will be in identified HCAs, Duke Energy plans to construct the entire pipeline to adhere to the more stringent regulations of the pipelines in HCAs.
  • Prior to installation, the lead engineer will confirm that the pipeline is constructed in accordance with the design. During installation, 100 percent of every weld will be X-rayed to confirm the weld meets the specifications. All joints must achieve 100 percent pass rate. 

    Prior to lowering the pipe into the trench, all pipes, including the joints, are checked for coating holidays, or defects, using mechanical detection equipment called a jeep. 

    Once the pipeline construction is complete, strength testing the pipe proves the structural soundness of the installed pipe and the capability to safely operate at the designed pressures. The pipeline will be filled with water, and the test pressure will increase to 1.5 times the maximum allowable operating pressure, which must hold for 8 hours. After this process, the pipe is certified and dewatered. The air will be purged from the line and natural gas introduced into the facility ready to commence operations.
  • Once the pipe is commissioned, there are requirements mandated by the code of federal regulations that ensure the pipeline is maintained and operated safely. 

    Annual Surveys: A leak survey is performed over the entire length of the line by patrolling over the top of the pipe with leak detection equipment, and a cathodic protection survey is performed and data is taken along the pipe to ensure the line is not corroding. The remote-control shut-off valves also are inspected annually to ensure the equipment is in the proper working condition.

    Quarterly Inspection: A line patrol is performed four times every year, during which the representative will walk the route, observing soil conditions, the coloration of the surrounding vegetation, encroachment concerns, and whether markers are in place. 

    In-Line Inspection: A safety standard required by the code of federal regulations is to design and construct this type of pipe so it can accommodate in-line inspection tools. This in-line inspection equipment utilizes non-destructive techniques to detect, measure, and record irregularities in pipelines. This data is used to determine the condition of the pipeline and identify safety concerns. This is performed on a cycle not to exceed seven years.

    Construction and Project Planning: As required by law, Duke Energy Ohio also locates its facilities for excavations. An inspector will be dispatched to a transmission line excavation site to observe and ensure the integrity of the facility when a third party calls 811 for an excavation. In addition, we will locate its facilities for planning projects. This aids in identification of facilities on plans to help reduce third-party damage.
  • Although Duke Energy is accountable for inspecting its pipelines, the Natural Gas Pipeline Safety division of the Public Utilities Commission of Ohio audits its inspections on a regular basis to ensure compliance with Ohio laws and federal laws governing safety.
  • Duke Energy follows regulations and industry best practices to identify and fix potential concerns before leaks occur. On the slight chance that a leak would be identified on this line, it would be repaired immediately.
  • Duke Energy Ohio's Gas Operations Department has not incurred any OSHA or PHMSA violations over the past 20 years in the state of Ohio on high-pressure distribution or transmission pipelines. 

    Five PHMSA violations have occurred from 1996 to present in the state of Ohio on low-pressure distribution pipelines. Duke Energy has taken precautions by implementing new work methods and safety precautions to continuously improve the safety of our pipelines.

    1998: A small pit hole in the 2-inch bare steel service allowed gas to migrate underground into the residence, resulting in an explosion. 

    How Duke Energy Changed: New software was implemented to alert our dispatch team when multiple odor calls occur within a certain distance and within a short time period. Additional crews are sent to the area to find the source of the odor and make the area safe if there is a leak on one of our pipelines. 

    We also implemented new work processes and 24/7 emergency response crews to enable a better response to odor notifications.

    2000: A service riser failed causing an explosion.

    How Duke Energy Changed: We implemented additional service riser inspections to look for corrosion or other factors that could cause a riser to fail. We also initiated a service riser replacement program to improve the safety of certain service risers.

    2006: A plumbing contractor auguring a sewer lateral struck a gas service, allowing gas to migrate into the home, resulting in an explosion. 

    How Duke Energy Changed: A public education campaign was developed to increase awareness to check sewer laterals before auger activities to ensure that no gas line crosses that sewer lateral. 

    Duke also initiated a sewer lateral camera program to identify similar sewer laterals and relocate any gas pipelines to remediate. We worked in conjunction with the Metropolitan Sewer District of Greater Cincinnati and Middletown Sewer District to develop safer procedures relating to trenchless technology around sanitary and storm sewers.

    2010: An apartment property maintenance worker remodeled a vacant apartment and failed to properly remove a gas line in the laundry room. The open gas line was ignited when the new tenant used a cigarette lighter, which resulted in an explosion. 

    How Duke Energy Changed: We updated procedures to include a pressure test for all gas meters being turned on.

    2016: An excavation contractor struck a buried gas service that had not been properly marked by a Duke Energy contractor, causing an ignition of gas and property damage.  

    How Duke Energy Changed: We reviewed the proper procedure with our local contractor, for situations when gas pipelines are unable to be traced and marked by electronic equipment. We established weekly and monthly meetings with the locating contractor to review their performance metrics, provided refreshed map training, stressed improved quality of their services and began conducting random checks of their work performance.

  • A final route has not been determined. Duke Energy has proposed a preferred and an alternate route to the Ohio Power Siting Board (OPSB). Both routes are located in Hamilton County and run roughly north to south from near the borders with Warren and Butler Counties to either the Fairfax or Norwood areas. 

    OPSB will make the ultimate routing decision.
  • Duke Energy identified through studies that it would need additional gas supply in the Greater Cincinnati area, specifically Hamilton County, which consumes 65 percent of the natural gas in the Ohio system on a peak day. The routes selected are those that provide the best solution to accomplish the goals of replacing aging infrastructure and providing system reliability. 

    Route corridors were selected that had the least amount of impact to residential areas, and both proposed routes have a mixture of residential, industrial, and commercial properties. 

    Miles of high pressure lines already exist, not only in Greater Cincinnati, but in many cities throughout the United States.

  • The detailed analysis is fully explained in our application to OPSB, but in general, the criteria are broken down into three, broad categories: 
    1. cultural and land use, 
    2. ecological, and 
    3. technical/engineering. 
    We reviewed many potential routes, including rail lines, utility corridors, and roadways. Although bypassing neighborhoods was not completely possible because of the urban environment of this project, the routing attempted to utilize commercial and industrial areas as much as possible to limit the impact to residential areas.
  • Both the preferred and alternate routes include parts where the new natural gas pipeline will be installed parallel to existing pipelines. However, most of Duke Energy's existing easements for high pressure distribution lines are not wide enough to construct a second pipe parallel to the existing pipe.
  • There is less chance of a contractor digging into the line if it is placed on private property than if it were in a public right-of-way. 

    Very few construction crews – such as those setting new poles or working on sewer and water lines – have the training or equipment to work on natural gas lines. Therefore, we try to stay as far away from them as practical to minimize the probability of accidents. 

    In addition, if there should ever be a need to widen the nearby road, we will already be out of the way of the new work. It is very expensive to shut down a line and move it, so we would rather address the issue during initial construction.
  • The Ohio Department of Transportation (ODOT) has restrictions in place in regard to new utilities and other non-highway related infrastructure within the highway right-of-way (ROW). We investigated the potential of occupying the ROW along I-71, which included discussions with ODOT regarding existing regulations and policies.

    As that investigation confirmed, ODOT generally does not allow "longitudinal" placement of utilities in the ROW for several reasons, including maintenance access, potential road expansions, public safety related to moving traffic, and utility construction and repair activities within the interstate ROW. 

    We, therefore, looked for opportunities to parallel I-71 without actually placing the pipeline within the ODOT ROW.

  • The OPSB Application requires a discussion of safety and safety-specific measures the Applicant will take to ensure the Project will be built to applicable safety standards. One of the voting members of OPSB is the director of the Ohio Department of Health. This individual evaluates the project in terms of personal safety related to what type of project is being proposed and what is provided in the project Application.
  • We have refined the routes based on thousands of comments we have received as part of the route selection process. We have met with developers and businesses along the routes to get more details related to specific parcels to select a preferred route that has the minimum impact on our customers and communities.

  • Duke Energy has completed multiple studies in determining the route location.

    Geologic Studies
    : A geotechnical investigation has been conducted to determine subsurface conditions and their suitability for the proposed routes and construction methods. 

    As part of the geotechnical investigation, soil samples have been collected and analyzed, as well as other testing to determine the corrosivity of the soils and determine what mitigation measures will be required. 

    Adjustments to the routing and construction methods will be made to address any anomalies or unsuitable conditions that are encountered.

    Environmental Studies: The OPSB process and the associated environmental permitting approvals require a wide variety of environmental studies for project approval.  

    The applicable environmental studies for potential project routes include but are not limited to: 
    • wetland and stream field evaluation and reporting,
    • threatened and endangered species and habitat assessments, 
    • cultural resource assessments, 
    • storm water pollution prevention assessment that is developed into the project Storm Water Pollution Prevention Plan, and 
    • Phase I Environmental Site Assessment. 
    The OPSB Application process also includes the above-mentioned, in addition to: 
    • evaluations of land use impacts, 
    • a siting/routing analysis, 
    • soil and slope evaluations, 
    • a description of public interaction activities, 
    • construction noise assessment, 
    • evaluation of potential impacts on agricultural lands, and 
    • an assessment of potential impacts on other non-protected categories of plants and animals.

  • An easement is a legal agreement that gives Duke Energy the right to use, NOT OWN, specific portions of land for certain purposes.
  • Duke needs easements to gain access to private and public property during construction and maintenance of natural gas pipelines. Placing pipelines on private property is a safe way to build and maintain the pipe.
  • The number of easements required for this project cannot be determined until the route is designed. Once the final route is laid out, we will begin contacting property owners to discuss their concerns and negotiate for the required easements for construction. We will work with individual owners to reach mutually acceptable terms.
  • Each proposed route will affect roughly 500 customers. Our intention is to construct the pipeline with the least impact on property owners, the environment and the communities we serve.
  • Yes. Easement fees are negotiated between Duke Energy and property owners at fair market values, depending on the size and location of the easement. Our company studies recent sales and values of comparable properties within reasonable distance of the proposed pipeline to get an idea of the market value of the land. The price of an easement will be less than the market value because we will not be buying the property outright, only the right to use it for a specific purpose.
  • Not necessarily. Duke Energy will make every effort to explain its figures fully and completely and will negotiate in good faith. Although all owners will be dealt with fairly, some may be paid more than others for their easements. Payments vary with the size of the easement, the amount of frontage included, and the underlying market value of the land.
  • We will work with individual property owners to minimize impact to the property and vegetation in the area and do our best to restore your property to its pre-existing condition or better than it was before the project began. In some cases, trees, bushes, and other vegetation might need to be removed for the construction work and will not be able to be replanted within the permanent easement. When required, Duke Energy Ohio will meet with you to ensure an alternate plan is in place. Any compensation would be part of easement negotiations.
  • The easement corridor is still being determined at this time. Depending on the location of the selected route, we may need to expand some easement areas more than others. This will be handled on a case-by-case basis with property owners.
  • When terms of the easement agreement are reached, a legal document is drawn up and signed by both parties. The easement is then recorded in the county recorder's office before construction begins.
  • If an agreement with the property owner cannot be reached, Ohio law allows Duke Energy to file a court action to acquire property. The court action would determine the value of the property that Duke Energy is seeking to use. In our experience, such court actions are not common.
  • Yes. After the pipeline has been constructed, owners can use their property as before, with a few exceptions. Roadways and sidewalks may be built within the easement as long as the existing grade is not changed. Other large, permanent structures such as homes, garages and swimming pools are not allowed because Duke needs to maintain access to this area for any future pipeline work.
  • Duke may need to access the easement periodically for inspections and maintenance.

    We would be responsible for repairing any damage we cause during future work. We will reserve the right to replace the pipeline in the future if necessary.
  • We try to stay 25 feet away for convenience of service, but theoretically, we could be only a few inches from your foundation if there was adequate work space on the other side of the line. 

    Please remember that if you have natural gas service, you already have a gas line into your home. Distances for the new line will vary. We intend to stay close to the road in front of any house. Once we have survey information, we will be able to design the project and show you exactly where the gas line will be.
  • Duke Energy does not anticipate having to tear down any residential properties in order to safely install, maintain, and operate the new pipeline.
  • Duke Energy is not a real estate expert, but there have been multiple studies and reports that show there is no relationship between the proximity of a pipeline and a sale price or value of a property.
  • To Duke Energy Ohio's knowledge, there has not been a case of a property owner becoming uninsurable or any premium increase due to a new gas line project.
  • Any landscaping or property that is disturbed will be restored to at least its pre-existing condition. This can include, but is not limited to fencing, shrubs, driveway asphalt and concrete, grass, etc. 

    Vegetation will be restored to prior condition with the exception that large trees and bushes will not be replanted within the permanent easement. We will work with individual property owners to minimize the impact to each property.

  • The overall construction process is expected to last approximately 16 months, occurring in phases or spreads. Construction affecting any one individual property will be of significantly shorter duration. Depending on factors including, but not limited to, property size, construction on each property typically occurs over a matter of 3-6 weeks.
  • There should not be any noise or odor from the pipeline during normal operations. Depending on the type of construction methods being used, construction noise will be typical for earth moving activities. Bulldozers, track-hoes and cranes will be utilized to facilitate the construction process. Duke Energy will endeavor to minimize the impacts of noise for residents during construction. 
  • Prior to digging, existing utilities will be located and marked to avoid any disruption to your service. Should service be temporarily disrupted, you will be notified immediately.
  • If any portion of the preferred route runs along or crosses a public road, it may be necessary to temporarily close a lane of traffic. Every traffic plan is unique and would need to be planned out with the corresponding jurisdiction. We will work closely with state and local authorities to minimize any traffic restrictions and we will have safety/flagger personnel on hand to assist motorists.
  • During construction activities, excavated materials will be controlled to minimize impact and reduce spreading dirt and debris from the construction zone. Street sweepers may be utilized to assist in keeping the area clean.
  • There will not be a continuously exposed or open 14-mile trench during construction activities. Rather, a trench will only be open as long as necessary to accommodate the safe installation of the pipeline segment. After all segments of pipeline have been installed, inspected, and backfilled, it will be subjected to a strength test.
  • Trench width will vary depending on the construction method and final pipeline design diameter. At the current 20-inch diameter design, the minimum width will be about 48 inches.
  • Excavators, cranes, rough terrain forklifts, pickup trucks and welding equipment will be necessary to build this pipeline.
  • The restoration process will be completed as Duke Energy progresses through the construction process; however, some areas, depending on weather conditions, will not be completed until more favorable conditions are available.
  • Duke Energy will contact businesses prior to the start of construction in their area to discuss proposed work schedules and potential impact to the business. To the extent practicable and taking into consideration neighboring properties, work schedules may be modified to accommodate businesses activities. 

    In terms of the Kenwood Towne Centre, if the preferred route is chosen, we will work directly with them to ensure we disrupt their business as little as possible, with the obvious understanding of the holiday shopping season.
