ERIE — Former Congresswoman Kathy Dahlkemper announced she's running in the May primary against Democrat incumbent Erie County Executive Barry Grossman.

The Erie Times-News reported that Dahlkemper says Grossman and other regional leaders have not “shown enough vision” on topics including economic development and keeping younger people from moving out of the state's most northwestern county.

Dahlkemper was elected to Congress in 2008, but lost Pennsylvania's 3rd District Seat to Republican U.S. Rep. Mike Kelly, of Butler, in 2010.

Grossman, who is 66, is seeking a second four-year term as executive and says Dahlkemper's announcement now gives voters a choice in the primary.

PITTSBURGH — A Pennsylvania congressman said a final decision on whether to close a Pittsburgh-area Air Force base may come this week.U.S. Rep. Tim Murphy said he expects the Air Force to announce its decision on the 911th Airlift Wing on Wednesday. Murphy, a Republican, said he's hopeful the base will be spared.Last year the Air Force announced plans to close the facility by September as part of a nationwide cost-cutting effort. Closing the base could save $354 million.But the plan was put on hold and reviewed after surrounding communities and politicians from both parties complained that the closing doesn't make financial sense.The base uses space at Pittsburgh International Airport. The unit includes eight C-130 refueling planes and about 2,000 personnel.

PITTSBURGH — A new scientific study on natural gas drilling and Pennsylvania waterways has found that old-fashioned erosion, not toxic chemical spills, appears to be more of a cause for concern.The peer-reviewed study published Monday took a statewide look at surface water impacts from the drilling boom. It found some good news and some reasons for concern.Lead author Sheila Olmstead said the research didn't find evidence of significant chemical spills from drill sites, but did note a five percent increase in suspended solids in downstream waterways. It also found a 10 percent increase in chloride levels downstream from plants that handle drilling wastewater.

GETTYSBURG — Demolition is under way at Gettysburg National Military Park on a building situated at the center of what were once the Union Army’s battle lines.Work to tear down the Cyclorama Building began a month ago with asbestos removal and is expected to last until late April, park spokesman Katie Lawhon said Monday.The removal is part of the National Park Service’s longstanding efforts to restore the park to conditions more closely mimicking 1863, when the property was engulfed by a pivotal battle in the American Civil War. The nearly $600,000 cost of the project is being paid by the Gettysburg Foundation.
