• As requested, the flows shown in Addendum No. 2 to the <br />Preliminary Engineering Report for the Orono -Long Lake <br />Interceptor are further revised in this Addendum. The flows <br />from the City of Maple Plain and the Vo -Tech area, Independence <br />Beach area, and Baker Park in the City of Medina have been <br />deleted from the contributing areas of the Long Lake pumping <br />station.. <br />The design year is revised to the year 2000 since <br />regulatory agency requirements are that a minimum twenty <br />year design period be used. Delays in the completion of the <br />project require that the design year be extended. The year <br />2000 is chosen because the system cannot be constructed and <br />operational before 1979. <br />A small increase in Long Lake flows is projected due to <br />further development and increased population in Long Lake in <br />the years 1995 to 2000. The increases are in keeping with <br />the population projections shown in the first Addendum to <br />the Report. <br />Exhibit B shows the projected average flows for .the <br />Orono and Long Lake pumping stations for the year 2000 from <br />the contributing areas. The total average flows are as <br />• follows: <br />Station Average Daily Flow (cfs) <br />Orono Metro 1.65 <br />Long Lake Metro 1.00 <br />Orono Municipal .09 <br />For the Metropolitan Pumping Stations, the design flows <br />are as follows: <br />Average Daily Flow <br />Orono 1.65 cfs 1.07 mgd <br />Long Lake 1.00 cfs .65 mgd <br />Peak Factor Peak Flow <br />3.3 2450 gpm <br />3.5 1600 gpm <br />
