Gaffron <br /> Assistant Planning and <br /> Zoning Administrator <br /> City of Orono <br /> P.O. Box 66 <br /> Crystal Bay, Minnesota 55323 <br /> Dear Mr. Gaffron: <br /> Re: Sewage Treatment Lagoon Abandonment and Sludge Disposal <br /> The Minnesota Pollution Control Agency (MPCA) has reviewed your letter of <br /> May 6, 1991. The comments in your letter properly represent our phone <br /> discussion regarding the issue of abandoning your sewage treatment lagoon and <br /> disposing of the remaining sludge in the bottom of the pond. <br /> Item #3 best represents the MPCA's opinion on how the abandonment should be <br /> handled. Any other alternative would seem to be only putting off the <br /> inevitable and would allow a potential source of pollution to remain. <br /> I contacted Mr. Gene Strommen of the Lake Minnetonka Conservation District, <br /> 900 East Wayzata Boulevard, Room 160, Wayzata, Minnesota 55391, <br /> (612) 473-7033. He indicated that his organization is very interested in how <br /> this pond is abandoned and would appreciate being contacted and kept informed <br /> regarding this issue. <br /> In addition, I contacted Mr. Jack Frost at the Metropolitan Council and <br /> Mr. Fred Bannister at the Metropolitan Waste Control Commission (MWCC) . Both <br /> felt that any sludge remaining in the cell should be properly disposed of <br /> before reusing the site. Mr. Bannister also indicated that it is very unlikely <br /> that the MWCC removed any sludge from the pond when it was taken out of service <br /> approximately 10 years ago. <br /> The Department of Natural Resources should also be contacted regarding the <br /> proposal to abandon the pond. They may have information regarding current or <br /> pending legislation rules regarding impacts on wetlands. <br /> Regional Offices: Duluth • Brainerd • Detroit Lakes• Marshall • Rochester <br />
