<br />- 23 - <br /> <br />C. The MWCC should continue land application of sludge from the <br />Empire Plant on its own property for the next four years. <br />The Council will consider this land as an ultimate disposal <br />site. <br /> <br />D. That the MWCC should construct anaerobic digestion and <br />dewatering facilities at the Blue Lake plant. Sludge should <br />be land applied to both private farmland and MWCC-owned <br />land. The Council will consider the currently owned land <br />for an ultimate disposal site. <br /> <br />E. That screenings and grit should continue to be put in <br />commercial landfills. If it becomes cost-effective to <br />dispose of these materials in MWCC-owned facilities, the <br />MWCC should so document in a Development Program. <br /> <br />. <br /> <br />F. <br /> <br />Sludge from the Anoka, Stillwter, Bayport, Rosemount, <br />Cottage Grove and Hastings plants should be digested and <br />applied to private farmland. I~ this option is not <br />feasible, this sludge should be hauled to the Metro plant <br />for processing and disposal in accordance with the MWCC's <br />facility plan. For the Chaska, Savage and Maple Plain <br />plants, their sludge should be hauled to Blue Lake for <br />processing and disposal. <br /> <br />G. The MWCC and/or the Council should undertake studies to <br />determine if the ash generated at the Metro Plant will be <br />hazardous waste, and if so, of poss~ble measures to mitigate <br />its hazardous nature. <br /> <br />H. <br /> <br />The MWCC should actively pursue the marketing of sludge, ash <br />and grit to reduce the amount of land needed for ultimate <br />disposal of these materials. <br /> <br />. <br /> <br />I. In lieu of landspreading of sludge with all its benefits, <br />another method of sludge disposal carried out in other parts <br />of the country is landfilling. The only advantage to this <br />alternative is that less land would be required to dispose <br />of the sludge. If one assumes that primary sludge would be <br />incinerated at Metro and the sludge incinerated at Seneca <br />for six months a year, approximately 200 acres would be <br />required for the remaining sludge to be landfilleq for the <br />next twenty years. If all the sludge is landfilled, <br />approximately 500 acres of land would be required. It is <br />recommended that this alternative not be pursued at this <br />time because of the benefits of landspreading and the <br />apparent demand for the sludge on private farmlands. <br />However, in the future if either incineration or land- <br />spreading of sludge become unfeasible, only then would it <br />become necessary to pursue landfilling of sludge or some <br />other method of ultimate disposal. <br /> <br />JF:sa <br />SA1662 <br />12/26/80 <br />
