. . - 22 - c. A total of 388 ~cres of land for a landfill for the Metro Plant ash would be needed if the total incineration mode of disposal is followed. If marketing of heat-dried, secondary sludge on private land is followed, then 25,000 acres will be needed for the heat-dried sludge and 226 acres for an ash landfill. D. 51 acres of land for landfilling of the Seneca plant ash would be required if total incineration is followed. If land application on private farmlands for six months is followed, 32 acres would be required for a landfill and 650 acres for landspreading. E. 220 acres of land for land application of sludge from the Empire Plant is needed. The MWCC currently owns this land, if this land is to continued to be used, the Council must selected it as one of the final sludge disposal sites. If another site needs to be chosen only 110 acres would be MWCC owned land and 110 acres private farmland. . F. Sludge processing facilities should be built at the Blue Lake plant. About 1350 acres of land is needed for land application of sludge: of this, 600 acres would be on private farms and about 750 would be on MWCC-owned land. If the land the MWCC currently owns is to continue to be used, the Council must select it as one of the final sludge dispo sal site s. G. For the Stillwater, Bayport, Anoka~ Rosemount, Cottage Grove and Hastings plants, the MWCC should pursue land application of digested sludge on private fa~mland. If this option cannot be implemented the sludge will be hauled to the Metro plant for processing and disposal. The sludge from Maple Plain, Chaska and Savage should be hauled to Blue Lake for processing and disposal. . H. Scree'nings and gritshouxd betaken to commercial landfills until it becomes cost-effective for the MWCC to put this material in their own facility. I. Metro Plant ash may be considered a hazardous waste once the current construction program is completed. J. A potential market for the reCYCling and reuse of sludge, ash and grit exists in the Twin Cities area. 8. RECOMMENQATIONS A. The MWCC should pursue marketing of heat-dried secondary sludge from the Metro Plant and continue to incinerate the primary sludge. B. The MWCC should continue total incineration of sludge from the Seneca Plant in the immediate future. However, as the MWCC's gains expertise" in landspreading it should pursu.e land application of all stabilized sludge for six months a year.
