Dredged Materials Management -Minnesota Pollution Control Agency Page 7 of 10 dredged materials that are distinctly different from each other. Subsets of dredged material maybe able to be managed differently from each other, depending on the Management Level applicable to each discrete subset. If subsets of Management Levels exist within the project, dredged material may be managed separately by subsets, i.e. each subset of dredged material is managed at the relevant Management Level; managed at the most restrictive Management Level, if separation and management by subset is not feasible or desired; or, managed at the most restrictive Management Level if subsets from a given project or multiple project, such as at a use/reuse staging area, are co-mingled prior to disposal. Table 5 in Chapter 5 of the management guide specifies the Soil Reference Values (SRNs) that are acceptable within each Management Level. For Projects Requiring a Permit For projects requiring either an individual or general permit for management of dredged material, the appropriate management requirements will be placed into the permit, and depends on the specifics of the project. General permit number MNG990000 was previously in place to authorize the management of dredged material for sites or projects meeting the criteria outlined in the permit. This permit is currently expired and is in the process of being reissued. Until the MNG990000 is reissued, alI projects required to obtain a permit are being issued individual permit coverage (see General_F'ermit Information section). An individual permit is developed for a specific project or site activity, with specific process waste water, discharge location(s) and situation in mind. In the application process, the following type of information would be submitted for the respective management area(s) and/or project(s) to be covered by the permit: . Description of the dredge project and any management area(s); . Description and status of receiving water; and, . The nature of the wastewater (what pollutant may be present). These factors, as well as additional factors about the receiving water, (such as its water use class and level of attainment or impairment, and whether there are any endangered species), are reviewed to determine the appropriate pollutant limits and monitoring. If either an individual permit or general permit coverage is required for your project, complete and submit the following permit application forms for MPCA review. . ~' ~ Transmittal Form . ~ ~ Attachment for Dred~ed_Material Management If a permit is issued for the specific project or site activity, the permit will be unique to the project and provide specific terms and conditions that must be met to legally discharge pollutants to waters of the state. The permit application forms should be submitted at least 180 days prior to the anticipated initiation of excavation.
