I I I CAB Interceptor Phase II extends the CAB Phase I facility through Champlin and crosses the Mississippi River to the Anoka STP. The project there phases out the Anoka STP. This project should be scheduled to be con- structed when the Anoka WWTP reaches its design capacity. This is a Service Area No. 2 and Service Area No. 3 project. This project is consistent with the WRMDG. Lake Virginia Pump Station and Force Main is consistent with the June 1984 Policy Plan amendment and provides relief for the overloaded Lake Virginia Pump Station, Excelsior Pump Station and Shorewood Interceptor I and II. This project is a 30 "Force Main which is planned to relieve the four overloaded facilities described above and will run directly to the Purgatory Creek Interceptor (6-SS-680; MSB 7801) which has adequate capacity. Previous projects proposed carrying the Lake Virginia relief to the Lake Ann Interceptor and thereby using all reserve capacity of the Chanhassen Pump Station and Interceptor. This alternative would require an in~nediate change in the Chanhassen Interceptor system by either placing a moratorium on Chanhassen growth, constructing a parallel force main adjacent to the present Chanhassen Interceptor or constructing the nine-mile long, all gravity, Riley Creek Interceptor. The Lake Virginia Interceptor, as proposed, will relieve four overloaded facilities in the Minnetonka Lake area and not affect the Chanhassen facility which has reserve for Chanhassen growth to 1998. This is a Service Area No. 4 project. Maple Plain-Pump Station and Force Main will phase out the WWTP at Maple Plain thereby eliminating the last sewage effluent discharge to Lake Minnetonka. The force main is to connect to the Long Lake Interceptor and flow through Wayzata to the Blue Lake WWTP. The force main running through the rural areas of Orono, will have restrictions on its use and will have no reserve capacity for rural area sewer service. This is a Service Area No. 4 project. Minneapolis East Interceptor Phase II is a continuation of the lower reach (Phase I) of this interceptor. Completion of Phase I and II will consist of approximately six miles of deep tunnel sewer which will connect the 98 inch diameter Fridley sewer to the Joint Minneapolis/St. Paul Inter- ceptor. This project will complete the interceptor relief needed for Northeast Minneapolis (serving area No. 1), and all of Service Area No. 2 and Service Area No. 3 at the time the Anoka Sewage Plant is phased out. The project is consistent with the WRMDG. Metro Ash Site Acquisition and Development is for the metro plant needs. After the Council has completed its siting process the Con~nission would proceed with the site acquisition and development. This is a system-wide project. The project is consistent with the WRMDG. Previously Acted on Projects: 11. Blue Lake Solids Disposal Phase I is for construction of sludge thickness at this time. At present, sludge thickening is done in one primary treat- ment tank. That tank is now needed for primary treatment because of increased flow at Blue Lake. Sludge thickening is needed for more economi- cal transportation of sludge to the Seneca STP for disposal. Construction is .planned for 1984. This is a Service Area No. 4 project.
