Dominion has completed construction of the Pleasant View — Hamilton 230 kilovolt line and Hamilton Substation.
Virginia's Loudoun County is one of the fastest growing counties in the nation. To meet the increased demand for electricity in western Loudoun County, Dominion has constructed a new 230 kilovolt (kV) transmission line to serve the areas west of Leesburg including Purcellville, Hamilton and Round Hill.
The new 230 kV transmission line extends from Dominion's existing Pleasant View Substation located east of Leesburg off Cochran Mill Road to a new substation site northwest of Hamilton, near the intersection of Berlin Turnpike and Rt. 7.
The Purcellville load area was being served by four long distribution lines (34.5 kV); two from Lovettsville Substation, one from Millville Substation in West Virginia, and one from Middleburg Substation. The new 230 kV transmission line and substation provides a new, local energy source to the area.
On February 15, 2008 the Virginia State Corporation Commission (SCC) issued a Final Order approving the Pleasant View-Hamilton 230 kV Transmission Line and 230 kV-34.5 kV Hamilton Substation.
Five alternative routes were evaluated ranging from approximately 12.0 miles to 15.3 miles in length. Both full length and partial length underground options were examined during the course of the SCC proceeding.
House Bill 1319
On March 6, 2008 the General Assembly established a pilot program (House Bill 1319 ) to underground certain high voltage transmission lines within the Commonwealth. This bill passed both houses of the General Assembly and was approved by Governor Timothy M. Kaine on April 2, 2008. The first project to be part of this pilot program is a portion of the Pleasant View to Hamilton 230 kV line.
On May 21, 2008, Dominion filed a "Modified Request" with the Virginia State Corporation Commission for approval to underground a portion of the Pleasant View to Hamilton 230 kV line project as a pilot, under 2.A of HB 1319 (>> View this filing: Modified Request). On May 28, 2008, Dominion received approval for this request (>> View this order: Case No. PUE-2008-00042 ).
Dominion is sensitive to public concern about possible health effects from exposure to electromagnetic fields. We continually monitor EMF research and speak to our customers and employees regularly to share the latest information available. The Virginia Department of Health, in its final report on EMF research said:
"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."
