Pipeline project gets permit needed for construction.

The Ohio Environmental Protection Agency on Tuesday granted NEXUS Gas Transmission a water-quality certificate.

NEXUS needed the certificate before it could start building its $2.1 billion, 36-inch diameter natural gas pipeline across Ohio.

The certificate requires NEXUS to have detailed plans for how it would deal with storm water and unanticipated leaks of drilling fluid during pipeline construction, two problems that arose during construction of the unrelated Rover Pipeline in Ohio.

The 255-mile NEXUS pipeline will start near Hanoverton in Columbiana County and cross Washington, Nimishillen, Marlboro and Lake townships in Stark County before entering the city of Green.

NEXUS is designed to carry up to 1.5 billion cubic feet of natural gas a day from the Utica and Marcellus shales to users in Ohio, Michigan and Canada. Detroit-based DTE Energy and Spectra Energy, which merged this year with Enbridge, a Canadian company, are partners in the project.

The Federal Energy Regulatory Commission approved the pipeline late last month but has yet to sign off on the construction plans.
