The Office of Business Operations (OBO) is responsible for managing many LM business functions related to the more than 100 sites across the United States and the territory of Puerto Rico. Many sites have no physical human presence, but some require years of additional monitoring, data collection, and inspection to ensure human health and environmental protection. OBO functions include records, data management, real and personal property, financial management, contract administration, human capital operations, correspondence management, and information technology, including cyber security.
