The Pennsylvania Department of Environment Protection and the U.S. Army Corps of Engineers have granted environmental permits for a Tulsa-based natural gas supplier's pipeline project.
The Tulsa World reports the Williams Partners pipeline project is a nearly $3 billion expansion of the existing Transco natural gas pipeline. It'll be extended to connect Marcellus Shale gas supplies in northeastern Pennsylvania to markets in the mid-Atlantic and southeastern regions of the country.
Williams also received approval to put a portion of the project into operation early.
The expansion project will allow for a 1.7 billion cubic feet (0.05 billion cubic meters) increase in daily delivery.
Construction on the project is expected to begin in the fall and be completed by mid-2018. The project is expected to cost about $1.9 billion.
