The Modernization, Accountability, and Planning for Broadband Funding Act seeks to enhance the Broadband Funding Map to optimize federal investments in broadband infrastructure. Its primary goal is to prevent redundant overbuilding by ensuring the most efficient use of federal funds for deployment. The bill directs the Federal Communications Commission (FCC), in coordination with the National Telecommunications and Information Administration (NTIA), to collect timely data from federal agencies for the map. The FCC must also initiate a Notice of Inquiry within 270 days to evaluate the map's functionality, transparency, and data quality, considering aspects like agency data submission, public usability, and potential expansion of reported data. Furthermore, the legislation mandates the Government Accountability Office (GAO) to conduct a study within 180 days on federal agencies' roles and progress in maintaining the Broadband Funding Map. This study will assess agency compliance with data submission, the FCC's management of the map, and the effectiveness of interagency coordination among key federal entities involved in broadband funding, ultimately exploring how improved map usage could lead to taxpayer savings .
