Encompasses keeping population densities below the carrying capacity of a region, facilitating the renewal of renewable resources, conserving and establishing priorities for the use on non-renewable resources, and keeping environmental impact below the level required to allow affected systems to recover and continue to evolve. Apply to Sustainable Sediment Management Comprehensive (Integrated) approach for addressing the long-term management / conservation of sediments within a watershed to maintain current (and future?) beneficial uses while addressing regional Environmental, Economic, and Social (and Political) concerns (challenges…).

Now that you’ve told me everything we can’t do… • No one wants to be # 1 - #2, # 3 is OK – Risk aversion – You haven’t built it… • Technology companies competing – but not understanding the sediment or waste business • No long term contracts – No Venture Capital • Not too many friends in innovative technology development– it’s lonely….

It probably is broken and you just don’t quite yet know how to fix it.. - stuck in the mud… Impedes innovative technology development Don’t discount sediment treatment as too expensive. Technologies over a decade that have stayed in the game have advanced through bench/pilot/full-scale programs with better economic data. This has caught up (w/in magnitude) with other alternatives Determine Life Cycle Assessment / Environmental Cost Benefit of paying more in the short-term as it relates to long-term sustainable approaches Please don’t tell me everything I can’t do – If you’re so smart please tell me what I can do. It’s easy to comment. More helpful if you get in the game and help / recommend technical/regulatory solutions. Don’t mortgage the future. Entertain moving forward with sustainable longterm solutions for dredged material and contaminated sediment management. When addressing sediment management solutions, approach it from an integrated systems approach. Sediment treatment can play well with others. It is not give me dcon or give me death. • Renewable CDF / beneficial use regional sediment management plan Sediment treatment development needs to take into account a treatment train approach. When the first 3,000 yd3 scow pulls up and the vendor say’s “wow” – this is not good sign….. Material handling – technology black box – post treated beneficial use applications Education among Us, Technology Firms, and Venture capitalists/Financing Firms • Know the business Do consider that treated contaminated sediments can be a resource with beneficial use applications. Apply state beneficial use guidelines Manufactured soils Construction-grade cement Aggregates Polymer coatings Waste to Energy / Gasification • Federal / State construction highway / transportation projects Economic stimulus There is a change in the wind….globally • [environmentalists] have become more equity conscious, and through their adoption of the sustainable growth logic of the appropriate technology movement, have largely cast off changes of obstructionism – Cicin-Sain and Knecht (1998) • Integrated Coastal and Ocean Management • ….need to be open to new ideas – need to change behavior………technology driven… Stern (2009) FIRST GPS – GOWANUS CANAL
