Pataki signed the bill into law during a ceremony at SUNY Institute of Technology.
The bill has drawn opposition from New York City Mayor Michael Bloomberg, whose city would benefit from the reduction in energy prices the line could bring.
Officials representing communities along the route the line would follow, however, have supported the bill.
The proposed route runs from Marcy through local communities including New York Mills, South Utica, Washington Mills, Chadwicks, Sauquoit, Clayville, Cassville and Waterville.
