Hydro One contractors have located the source of a so-called “leaking line” under the pavement in the westbound lanes at the Millwood Rd. railway underpass. The pinhole-sized leak was found on Wednesday morning, the utility tells The Bulldog. The search for the leak began in May when Hydro One’s Ontario Grid Control Centre was alerted to irregularities in an underground transmission line. Hydro One said in a statement that: “It was determined that the issue was that non-toxic mineral oil which is used to insulate the line had leaked. The mineral oil was contained within the cable’s surrounding duct so there was no risk to the environment however, our environmental team followed our strict procedures to report and investigate the leak.” Thus it appears that the end of the westbound closure is closer but still not exact. “We know this is causing an inconvenience to local residents and appreciate their patience while we work to ensure the safety and reliability of our electricity system,” says the Hydro One email.
