Not law, yet. Here's a potion of the PGC release:

"As recommended in the recently released Urban/Suburban Deer Management Plan, the Pennsylvania Board of Game Commissioners today gave preliminary approval to a regulatory change to permit the use of bait in Bucks, Chester, Delaware, Montgomery and Philadelphia counties, as a means of increasing hunter harvest in these highly-developed areas.

While illegal in other parts of the state, the General Assembly and Governor Rendell, in 2004, approved a change to state law to authorize the Game Commission to permit the use of bait for deer hunters in special regulations areas counties, except for Allegheny County. After examining other state's methods of permitting baiting and development of an Urban/Suburban Deer Management Plan, the agency took action to permit baiting within the parameters of the law."

Note that this was preliminary approval, are taking comments, and would be subject to possible final approval in October.

I doubt if it could be implemented this season.
