In Aberdeen, the impact of sequestration will not just be felt on post.

"The impact of a 22-day furlough would be 20 percent less payroll coming into Aberdeen," Dean Ertwine said.

Ertwine is a retired Army brigadier general whose last assignment was to the Developmental Test Command at APG.

The Bel Air area resident is vice president of the Army Group at Battelle, a worldwide nonprofit research and development company headquartered in Columbus, Ohio. The firm provides a variety of support services to the U.S. military, Department of Homeland Security and Department of Energy.

It is one of a number of companies with a presence in Aberdeen to support the mission at APG.

Battelle operates the BEST Center (Battelle Eastern Science & Technology) in Aberdeen. The BEST Center provides laboratories and other services to support programs at APG and the post's other local facilities to develop defenses against and responses to chemical, biological, radiological and nuclear attacks.

Ertwine said about 200 people are employed at the BEST Center, and 60 to 80 percent of them live in Harford County.

"We've been impacted, just like other companies," he said.

Ertwine said a number of measures have been put in place at the BEST Center "to control or reduce overhead so that we've been able to avoid releasing staff in any significant numbers."

He said conference attendance has been reduced, the firm has been very "selective" about organizations that it sponsors or maintains memberships in, and has cut advertising to "practically nothing."

Members of Congress are working to find a solution to avoid sequestration.

"We must stop sequester with a balanced approach to reducing our debt and deficit that includes reforms to the tax code, strategic cuts to mandatory spending and gives credit for cuts already taken," U.S. Sen. Barbara Mikulski, a long-serving Maryland Democrat, said Sunday. "We can do it if we work in a bi-partisan way across the aisle and across the Capitol dome to agree on closing tax loopholes and making strategic cuts while maintaining our investments in education and innovation. That's how we'll create jobs today and jobs tomorrow, accelerate our economy and reduce our debt and deficit."
