46 Existing Disposal System Currently the grit and screenings are taken to commercial landfills; sludge. .--is landspread_ __°n private. . property.. _, commission-owned property or Incinerated and the ash is landfllled. The two largest treatment plants in the metropolitan system, the Seneca Plant in Eagan and the Metropolitan Wastewater Treatment Plant--~n St. Paul, together inciner- ate about 90 percent of the sewage's--~-~g~ 'pro-o---~uce-e--~_~ the trea~-~ plants ~-~ the metropo~-~t~-~-system. Incinerator ash from the Metro Plant is presently land-spread at the site of the old closed St. Paul la-~i~ near the Metro Plant. Seneca Plant ash is spread on land adjacent to the plant site. Grit and screenings from all metropoli- tan plants are presently landfilled at the neares~ ~nitary landfills. Planning for Future Needs A__s part of the MWCC's 201 Facility Planning Program, the processing and disposal of all wastewater residual solids have been evaluated on _a ~lant_ __and regional, basis. Table 4 ident~s' the qu-~tities of grit, screenings and Fudge produced by each plant in 1980 and esti- mates the expected production over a 20-year period. The Council generally reviews the wastewater residual solids management program of the MWCC and approves management systems to implement the pro- gram. However, the Waste Management Act (Minn. Statutes 473.152 Subd% 2) transferred the authority ~q selec~ fin~-f ~ sites for resldu~ solids from the MWCC to the Council. ~'July 1__~9~, ~h~ Council must select three candidate sites each for sludge and ash disposal. In the selection process, no land is excluded from con- sideration unlessdeclared intrinsically' ' ' -- -- ~'unsu~table .... by the ---=~ --M~nnesota Pollution Control Agency. Once candidate sites are selected, a moratorium is imposed on further development wit~-~-6 6he site and b~ffer zone.

Thereafter,. the MWCC can acquire and develop the sites as needed. Any waste facility owned or operated for or by the MWCC must conform t__o.thi._~_~s plan..

To meet the disposal needs of the MWCC's treatment plants in an efficient and environmental~ safe manner. 9b. To promote recoverz and reuse of energy and nutrients from r-~sidual sollds'--~-. -- 9c. To encourage the MWCC to develop environmentally safe and economically viable alternatives to landfilling residual solids.
