2 The facility will house processing equipment including separators, vats, and tanks to extract metals from the waste received from metal finishers. Specially designed trucks, semis and tank trucks, will transport waste material from the metal finishers to the facility. Solid wastes, liquid wastes and ion exchange resin canisters containing cadium, chromium, copper, lead, zinc, nickel and other metals generated by metal finishers will be processed at the facility. Some metals will be recovered for sale and reuse. Liquid organic wastes and organic sludge will be stored at the facility and shipped to appropriate disposal sites. Unrecoverable wastes will be transformed into solids to be disposed in approved landfills. Organic liquids and sludges will be stored for transshipment to appropriate out-of-state treatment and disposal facilities. As of August 30, 1984, 29 out of a possible total of 96 Twin Cities metal finishers and electroplaters which are subject to the Metropolitan Waste Control Commission (MWCC) effluent limitations had contracted to utilize the proposed central facility. However, other companies included in the 96 have expressed interest in utilizing the facility once it is in operation. There are also 104 facilities which are not subject to the MWCC limitations, such as some steel treatment facilities, thpt could potentially use the proposed facility. Currently, the 29 shops committed to utilizing the proposed facility have signed "put or pay" contracts. Data from these contracts yield the following estimate of the minimum number of canisters and weight or volume of bulk dump liquids and sludge cake to be handled at the proposed facility: 3,207 canisters, 335,975 gallons of bulk dump liquids, 128 drums of dewatered sludge, and 33,279 pounds of wet sludge per year. Total cost of the project is estimated at $6 million, about $5 million plus land costs. [1, 2, 5] B. Permits and Approvals Required The py)ject will require permits and approvals from the U. S. Environmental Protection Agency (EPA), Minnesota Department of Energy and Economic Development, MPCA, WMS, MWCC, Ramsey County, and the City of Roseville. The MPCA will be delegated the authority to issue the Hazardous Waste Treatment and Storage Facility Permit by the U. S. EPA in January or February of 1985. When this permitting function is delegated to the MPCA, a Resource Conserva- tion and Recovery Act (RCRA) permit will not be required from the EPA. [11 2, 6]
