In addition to characterizing dredged material, any non-exempt discharge from a project and/or management unit requires complete characterization. Characterization of effluent from the dredge project site and/or management unit(s), if proposed, are described in Chapter 4 of the management guide; exempt discharges are described in Chapter 5 of the management guide. Do I Need a Permit for my Site or Project? Except for specific situations, a permit is required for the management of dredged material in the state of Minnesota. The type of permit required will vary, depending on the level of pollutant contamination in the dredged material, whether effluent is being discharged, and how the dredged material and/or effluent is being managed. Figure 1 is intended to guide users through the process of determining appropriate management options for dredged material, and the associated permitting requirements for various management methods. Answering "yes" or "no" to a question will lead to the respective answer, in terms of how to proceed through the flow diagram, and the regulatory controls of a particular management route. Figure 1.
