DMMP Program Updates

Adaptation is an integral part of the Dredged Material Management Program as science evolves, regulations change, and experience and data inform us. Program updates and changes are proposed at the Sediment Management Annual Review Meeting (SMARM) by agencies or interested parties. All proposals are either accepted, dropped, or modified based on feedback from the SMARM process.
