NASHVILLE (AP) - A natural gas distributor plans to run a pipeline through a state nature preserve and high-priced neighborhoods on Nashville's south side.

Piedmont Natural Gas plans to use a TVA utility easement to bury at least part of a 13.5-mile gas line through the Radnor Lake Natural Area and the upscale Forest Hills and Oak Hill communities, according to The Tennessean (http://tnne.ws/yuwN7F).

Letters should begin arriving on Thursday, informing property owners that the project could cross their land.

Piedmont spokesman David Trusty said the company wants to do land surveys and core drilling that could affect residents' property.

Trusty said the $60 million cost of the new line has been figured into a fee increase recently approved by the state.

The Friends of Radnor preservation group is seeking more information.
