Roseville Public Works, Environment and <br />Transportation Commission <br />Agenda Item <br />Date: November 24, 2008 <br />Item No: 5 <br />Item Description: Pond/ Ditch Maintenance Regulation Update <br />The MPCA has specific and detailed protocols for dealing with dredged materials. These <br />protocols were not written with storm water ponds in mind. Following the protocols for testing <br />and disposing of contaminated dredged materials can result in making a storm water pond <br />dredging project very expensive. For more information you can go to the MPCA site: <br />http://www.pca.state.mn.us/water/dredgedmaterials.httnl <br />The MPCA has begun the work effort to reissue the expired general permit for the management <br />of dredged materials (MNG990000); a preliminary permit has been drafted. The MPCA will <br />soon be requesting input from representatives from public and private organizations involved in <br />dredging activities to further clarify the scope of the permit, including work on further defining <br />projects that do (and do not) need a permit, as well as the consolidation of construction storm <br />water standards into the General permit. Here is the schedule posted on their webpage: <br />Task Date(s) <br />Develop permit ` Begin July 2005 I, <br />Review of permit (internal and external), respond to ~ <br />comments (stakeholder meetings) Fall 2007 - Fa11200~ ~ <br />Publish public notice of draft permit I Fa112008 i <br />Respond to comments and finalize permit <br />• no hearing request <br />• with hearing request <br />• .., 3 - h months after public notice <br />• ~ 10 months after public notice <br />MPCA Citizens' Board decision on permit ~ <br />__ _ Spring -Fall 2009 <br />f <br />Permit reissued '~ Fall 2009 <br />We have been strongly advised by the Minnesota Cities Stormwater Coalition to hold off on any <br />stormwater pond dredging projects until the MPCA has revised their permit. <br />Recommended Action: <br />Discuss regulations <br />
