Crews have begun preparing the new right-of-way for upcoming transmission line construction. See the "Construction Updates" link below for additional details.
To maintain reliable electrical service in the area, Dominion will construct a new 230,000 volt (230kV) transmission line in Prince William County and the City of Manassas within existing right-of-way. This project includes a new Liberty Substation in Prince William County to be built on land Dominion has already acquired.
On June 29, 2012 Dominion filed an application with the Virginia State Corporation Commission seeking approval for these new facilities. The SCC issued a Final Order on April 17, 2013, approving the line and substation.
Transmission Line Work
Construction of the transmission line is scheduled to begin in May 2014. Prior to actual construction, you may see crews in the right-of-way testing the soil, surveying, clearing trees or vegetation, or installing gravel or timber matting access roads.
Once the right-of-way is cleared and prepared for construction, the following activities may take place:
Liberty Substation Work
Work on the substation will take place entirely within the substation or within the transmission right-of-way corridor, and may include:
Dominion filed an application with the SCC on June 29, 2012, and it was approved on April 17, 2013.

To maintain reliable electrical service in the area, Dominion plans to construct a new 230,000 volt (230kV) transmission line in Prince William County and the City of Manassas within existing right-of-way.

The State Corporation Commission (SCC) is responsible for determining the need, route and environmental impact of transmission lines at 138 kV and above in Virginia.
Dominion filed an application with the SCC on June 29, 2012. Documents related to the case number PUE-2012-00065 are made available to the public on the SCC Docket Search section of the SCC website. A Hearing Examiner’s Ruling was issued, which includes a revised Procedural Order.
The SCC Staff Report concluded in January 2013, that the Company has reasonably demonstrated the need for the proposed 230 kV Cloverhill-Liberty Line, double-circuit 230 kV Liberty Loop, and Liberty Substation. Since the proposed route totally uses existing right-of-way, the Staff concludes that the proposed routing reasonably minimizes the adverse environmental impact to the surrounding area and that it is an optimal route.
The SCC issued a Final Order on April 17, 2013, approving the Cloverhill-Liberty 230kV line and substation.

Due to the interconnected nature of the electric transmission grid, all power users in the area rely on Dominion's transmission infrastructure to deliver reliable power. The new 230 kV lines will provide increased operational flexibility and greater system reliability. As an area resident, this means fewer outages, and shorter durations should an outage occur. Additionally, the localities ultimately crossed by these lines will each benefit from the increased property tax revenues paid by Dominion.
As part of the SCC application, Dominion completes an evaluation of potential environmental, cultural, and historical impacts of the project. Dominion works with many local and state agencies to complete these evaluations and reasonably mitigate any impacts. The company also submits annual Erosion and Sedimentation (E&S) Control Specifications and an anticipated list of transmission line projects for the construction and maintenance of transmission lines to the Virginia Department of Conservation and Recreation for review and approval. This project will be included in the annual submittal for approval prior to construction. Our contractors receive copies of the E&S specifications and any additional permit conditions prior to construction and are directed to meet any requirements. The right-of-way will be rehabilitated when construction is complete.
Our enterprise-wide environmental report describes our commitment to responsible stewardship of natural resources and provides a wealth of information on environmental management and performance. We also invite you to read our Corporate Environmental Policy and our Greenhouse Gas report.
The company’s construction of new transmission line facilities complies with the Chesapeake Bay Protection Act (CBPA) in accordance with 9VAC10-20-150. This Virginia Administrative Code provision provides that construction, installation, operation, and maintenance of electric transmission lines comply with Virginia’s regulations implementing the CBPA if such construction, installation, operation and maintenance adhere to any one of the following:
(i) regulations promulgated pursuant to the Erosion and Sediment Control Law (§10.1-560 et seq. of the Code of Virginia) and the Stormwater Management Act (§10.1-603.1 et seq. of the Code of Virginia),
(ii) an erosion and sediment control plan and a stormwater management plan approved by the Virginia Department of Conservation and Recreation, or
(iii) local water quality protection criteria at least as stringent as the above state requirements.
The company adheres to both items (i) and (ii) by complying with annual Erosion and Sedimentation Control Specifications for the construction and maintenance of transmission lines as reviewed and approved annually by the Virginia Department of Conservation and Recreation. In addition, the company obtains a Virginia Storm Water Protection permit for each project and we follow required inspection and recordation procedures during construction, which in many cases exceeds CBPA standards. We also make use of matting systems which reduce or eliminate the disturbance to sensitive wetland ecosystems. For more information visit the Virginia Department of Environmental Quality website on the CBPA.
Easement agreements (also referred to as "right-of-way agreements") provide Dominion with a specified set of property rights needed to construct/rebuild, operate and maintain electric facilities across real property. At the time the easement is acquired by Dominion, land owners are compensated based on the fair-market value of the property acquired for the easement and any damages to the remainder of the property outside the easement area. The property owner(s) still own(s) the land but the easement rights granted to Dominion are perpetual and run with the title to the land.
Dominion compensates property owners only at the time a new easement is acquired. New easements will mostly likely not be necessary for the Cloverhill-Liberty project.
Property owners of record when the easements were first acquired were compensated and the easements were filed with county/city records departments.
For a copy of the easement that covers your property, contact your local county or city land records office. Dominion can also provide you with a copy. Email your request to firstname.lastname@example.org with "Easement request" in the subject line. Allow up to six weeks for processing. For more information regarding Dominion easements, visit our website Right-of-Way page.
Dominion is sensitive to public concern about possible health effects from exposure to electric and magnetic fields (EMF). Dominion includes data on the levels of both electric and magnetic fields produced by proposed facilities in all applications submitted with the SCC. We continually monitor EMF research and speak to our customers and employees regularly to share the latest information available.
The Virginia SCC, which regulates the construction and operation of electric transmission lines of 138kV and above, considers EMF in every application. Hearing Examiner’s remarks from recent proceedings are below.
The Virginia Department of Health in its final report evaluating EMF research concluded:
"Based on the review and analysis of the exhaustive literature review and other research projects completed under the EMF-RAPID program, the Virginia Department of Health is of the opinion that there is no conclusive and convincing evidence that exposure to extremely low frequency EMF emanated from nearby high voltage transmission lines is causally associated with an increased incidence of cancer or other detrimental health effects in humans. Even if it is assumed that there is an increased risk of cancer as implied in some epidemiologic studies, the empirical relative risk appears to be fairly small in magnitude and the observed association appears to be tenuous. The studies published in the literature lack clear demonstration of a cause and effect relationship as well as a definitive dose-response gradient."
