The Postal Service completed its study to determine which facilities to consolidate and how the agency should go about consolidating them.
The Postal Service said Thursday it assessed 264 processing facilities for possible consolidation.
In a fact sheet, the agency said 35 of those facilities will remain open while 223 have been found feasible for partial or complete consolidation
Six facilities had their status listed as to be determined, needing further internal study.
The Postal Service projects consolidating facilities will save $2.1 billion.
The study is part of the Postal Service’s larger effort to eliminate $20 billion in costs by 2015.
The consolidation plans are contingent upon pending rulemaking and will not start until after May 15, giving Congress and the White House time to propose an alternate plan.
The Postal Service projects consolidating facilities will eliminate 30,000 full-time positions and 5,000 non-career positions.
However, the Postal Service said it will aim to find openings for employees at other locations.
