This legislation directs the Comptroller General of the United States to conduct a comprehensive review of the Mid-Atlantic River Basin Commissions, specifically the Susquehanna, Delaware, and Interstate Commission on the Potomac River Basin. The primary goal of this review is to enhance transparency and congressional oversight of these regional bodies. The Comptroller General's review will examine several key areas, including the ethics policies and practices of each commission, their methods for communicating with the general public , and the nature of current Federal responsibilities . It will also detail the sources and levels of Federal and State funding received, and identify any commission duties that may be duplicative of, or overlap with, other Federal authorities . Following the review, the Comptroller General must submit a report to Congress containing findings and recommendations for statutory or administrative changes to increase transparency and oversight. Subsequently, each Mid-Atlantic River Basin Commission is required to submit an annual plan for five years, detailing actions taken to comply with these recommendations.
