Part of: Dredging and Dredged Material Disposal
A case history of the federal, state and local permitting process for the dredging and disposal of dredged material of a tanker/barge terminal in Boston Harbor is discussed. The dredging was required to maintain necessary water depths at the tanker and barge berths. The total quantity of dredging was 15,000 cubic yards of material, of which approximately 5,000 cubic yards were virgin material and the remainder was the result of approximately 10 years of siltation. The permit process from application to approval took approximately twelve months. Engineering fees for preparation of permit applications and environmental testing fees cost approximately 23,000. The actual cost of dredging and disposal of the 15,000 cubic yards including mobilization/demobilization was 85,000. The cost of permit application, approval and environmental testing represents almost 25% of the total cost of the project.
