The program would provide funding to meet state and federal permit compliance schedules for sewer separation in the metropolitan area and also funding for outstate communities to meet federal Clean Water Act requirements. An annual appropriation in the $40 to $50 million range will be requested. Of this amount, 2/5th3, or from $16 to $20 million, would be available to the Twin Cities Area for sewer separation, with 3/5th3 allocated to the rest of the state to meet mandated federal water quality deadlines. The metropolitan area portion, plus a Share of the state's federal construction giant allotment dedicated to sewer separation, would be matched dollar -per -dollar by the three cities with local funds over a five-year period. Total estimated cost for the sewer separation program, not counting regional facilities, is $214 million. WHY IS THE SEPARATION PROGRAM NEEDED NOW? When it rains very hard. millions of gallons of rainwater, combined with untreated sewage and ogler wastes, Dour out of V bypass pipes directly into the M1_231331ppi River. Normally, the pipes convey the wastewater to the Metropolitan Waste Control Commission's Metropolitan Wastewater Treatment Plant in St. Paul for treatment. However, the interceptor sewers leading to the plan.;, and the already huge plant are not large enough to handle heavy rain flow, so automatic bypass gates in the sewer system are opened to divert the wastewater into the river. During a yens with average rainfall and snowmelt, an estimated 4.o billion gallons of mixed sewage and 3tormwater pour into the river. It occurs, on the average, every three days during warm weather. Heavy rainy also cause local street flooding and sewer back ups in homes in some areas served by combined sewers. The federal C'_ean Water Act prohibits the discharge of untreated sewage into any of the nation's waters. Rather, all sewage must receive treatment so advanced that 90 percent of the pollutants are removed prior to discharge into a water body. The combined sewer overflow discharges require a state permit ac-,eptable to the federal government that acknowledges the violation but includes a :mandatory plan and program to end the discharge. The discharges can be eliminated by completing a storm and sanitary sewer separation program initiates] by the cities many years ago, or by collecting, storing and treating all the combined stormwater and sewage. The Metropolitan Wastewater- Treatment Plant currently treats 73 billion gallons of wautewater annually. It now meets state and federal standards. This was no'.
