However, it does not provide a reliable basis for deciding whether to proceed with the project. In particular, GAO's analysis of the Corps' 1998 benefit estimate identified several miscalculations, invalid assumptions, and the use of significantly outdated information. In addition, a number of unresolved issues and uncertainties were not factored into the Corps' economic analysis, the outcome of which could either increase or decrease the benefits and costs of the project. Due to the shortcomings GAO identified in the Corps' analysis, the actual economic merits of the project will not be reliably known unless the Corps comprehensively reanalyses it. The Corps of Engineers has largely addressed environmental concerns related to the project to the satisfaction of federal and state environmental agencies. However, a number of unresolved issues remain, including the issuance of a permit from the state of Delaware governing construction projects that affect state waters. https://www.govinfo.gov/content/pkg/GAOREPORTS-GAO-02-604/html/GAOREPORTS-GAO-02-604.htm GAO-02-604 https://www.govinfo.gov/app/details/GAOREPORTS-GAO-02-604 Other Written Product GAO-02-604; Delaware River Deepening Project: Comprehensive Reanalysis Needed; Cost analysis Environmental engineering Marine engineering Economic analysis Inland waterways Waterway costs Land management Environment evaluation Delaware River
