The Treasury Department has agreed to delay for five years a plan to relocate 450 jobs out of Prince George’s County to Parkersburg, W.Va., after Maryland lawmakers pressed federal officials to abandon the plan.

The reprieve was announced by Maryland lawmakers, led by U.S. Sen. Barbara A. Mikulski (D), who recently took the reins of the powerful Senate Appropriations Committee, where she would be in a position to block the move.

The original plan, announced last summer, gave employees — mostly in accounting and IT, with typical GS-12 salaries around $60,000 — until January 2015 to relocate or leave the agency, part of the Treasury’s Federal Management Services operations in Hyattsville in Prince George’s. The plan called for the jobs to be moved to Parkersburg beginning this year as part of an agency consolidation with the Bureau of Public Debt.

“Today’s announcement is good news for jobs in Prince George’s County, for Maryland and for the duty-driven civil servants at the Hyattsville FMS facility dedicated to good government and public service,” said Mikulski in a written statement.

“We must have a more frugal government, but not one that hangs our people out to dry. Together with Team Maryland, I fought to keep these jobs in Prince George’s County. These hardworking civil servants have training, expertise and institutional knowledge that can’t be reproduced anywhere else. They deserve a government that is on their side, and I will continue to fight for them.”

The delay, which could eventually lead to a reversal of the relocation plan, was lauded by Prince George’s County Executive Rushern L. Baker III (D), who has made job creation and economic development a cornerstone of his administration’s goals.

In a written statement, Baker said he hoped the delay would lead to a decision to keep the jobs in Prince George’s permanently.

“I want to applaud the General Services Administration and the Treasury Department for recognizing the importance of keeping these jobs in Prince George’s County, close in proximity to other related government entities, near transit and, most importantly, where these workers live,” he said.
