ALBANY, N.Y. -- Proponents of shale gas drilling have launched a new ad campaign calling on state officials to bring a four-year environmental review to a close and allow gas development to begin in New York.

The radio and print ads were released Tuesday, in advance of a Nov. 29 deadline for finalizing regulations for gas drilling and high-volume hydraulic fracturing, or fracking. Gov. Andrew Cuomo has said it's unlikely the deadline will be met because a health study is yet to be finished.

Shale gas drilling hasn't been allowed in New York since regulators began an environmental study in 2008.

The ads were launched by a group of landowner, farming, business, gas industry and construction organizations. It contrasts economic hardships in upstate New York with financial benefits drilling has brought to Pennsylvania.
