The MPCA staff <br /> stated that the 1 mg. per liter standard is applied to the <br /> effluent because of the discharge to the lake and that there <br /> was no limit on a phospherous content if it discharges into <br /> the river. <br /> Mayor Van Nest reviewed the general import of the 1969-1970 <br /> Harza study. Ne noted that the lakeshore around Lake Minnetonka <br /> had been urbanized years ago because of the attraction of the <br /> lake as a recreational facility. Away from the lake. most <br /> of the area in the Cities of Orono , Minnetrista , Independence <br /> and Medina was rural in nature. Mayor Van Nest explained the <br /> cycle wherein if one brings interceptors into an area, then <br /> laterals are extended from the interceptors , and there is dense <br /> urbanization that follows in order to be able to pay for the <br /> cost of the installation of the trunks and laterals . In fact , <br /> he noted that in 1973 , the engineers for the City of Orono <br /> recommended a $10 ,000 ,000 trunk and lateral sewer project <br /> through the rural areas of Orono and the citizens unanimously <br /> stated they did not want that sort of urbanization in rural <br /> Orono. Moreover , the Harza study shows that that sort of <br /> urbanization would lead to the pollution of the watershed in <br /> Lake Minnetonka because of the increased phosphorous load which <br /> woUld be in the surface water runoff with that level of <br /> urbanization. He stated it is a well-known fact with which <br /> everyone agrees that the amount of phosphorous increases with <br /> urbanization. With urbanization, the increased surface water <br /> runoff takes the dying vegetation and other phosphorous loads <br /> directly into the lake . Mayor Van Nest indicated that he had <br /> sent a copy of the Hickock report from 1973-1974 , to the MPCA <br /> which shows that in an urbanized area , as much as 3 .68 pounds <br /> of phosphorous per acre is discharged into the lake versus <br /> . 3 pounds per acre in a two acre developed zone. The mayor <br /> stated that when you install trunks and laterals around the <br /> lake , it is very expensive , as high as $12 ,000 per unit , and <br /> that therefore you force intense urbanization with the resulting <br /> . adverse environmental effect . Mayor Van Nest noted that the <br /> City of Orono , through its council and staff , has studied this <br /> problem for over eight years and that the city has decided <br /> � as part of its comprehensive land use plan to prohibit this <br /> sort of urbanization in part because of this adverse environmental <br /> effect on the watershed and Lake Minnetonka. Mayor Van Nest <br /> then explained in detail how the City of Orono had implemented <br />
