I have to amend my previous post to include this Wired article that specifically mentions the Catawissa site as a currently active AT&T international satellite hub that is tapped by the NSA.
The NSA Is Building the Country's Biggest Spy Center (Watch What You Say) | Threat Level | Wired.com
The eavesdropping on Americans doesn’t stop at the telecom switches. To capture satellite communications in and out of the US, the agency also monitors AT&T’s powerful earth stations, satellite receivers in locations that include Roaring Creek and Salt Creek. Tucked away on a back road in rural Catawissa, Pennsylvania, Roaring Creek’s three 105-foot dishes handle much of the country’s communications to and from Europe and the Middle East. And on an isolated stretch of land in remote Arbuckle, California, three similar dishes at the company’s Salt Creek station service the Pacific Rim and Asia.
