The Federal Government Processes Retirement Claims in a Limestone Mine. 230 Feet Underground. By Hand.

The Office of Personnel Management processes federal civilian retirement claims from a converted limestone mine in Boyers, Pennsylvania — roughly 230 feet underground. Approximately 700 federal workers commute underground every day to process paper retirement files stored in steel-lined rooms carved out of the rock. The facility has been in continuous use since the 1950s, when the mine was converted to a federal records storage site during the Cold War, when underground facilities were valued for their survivability.

The Cold War is over. The mine is not. Every federal civilian retiree’s pension claim still flows through a manual, paper-based process, because OPM’s retirement systems have never been successfully modernized. GAO has flagged the OPM retirement IT modernization project as a failure or at-risk project in nearly every report since 2008. Multiple attempted system replacements have been abandoned after hundreds of millions in spending. The limestone mine is not a quirk — it is the active, primary retirement processing operation for 2.7 million federal civilian employees.

The result is a persistent claims backlog. In 2023 and 2024, tens of thousands of federal retirees waited four to six months for their first pension check. The average processing time for a retirement claim runs 60–90 days under normal conditions. The federal government manages to deposit Social Security benefits electronically within 24 hours of the start of the benefit period. Federal civilian retirement, administered by a different agency from a limestone mine, routinely takes months.

OPM has attempted and failed to modernize its retirement system at least three times since 2003. The most recent major attempt — the Retirement Systems Modernization project — was formally terminated in 2011 after absorbing $231 million without producing a working system. Subsequent incremental modernization efforts have made partial improvements but have not eliminated the paper-based core processing operation in Boyers.

GAO placed OPM retirement modernization on its High Risk List in 2019. It remained there as of 2024. The Office of the Inspector General for OPM has consistently identified the retirement processing backlog as a top-five management challenge. Congress has repeatedly appropriated funding for modernization. The limestone mine remains the operational center of the federal retirement system.
