POPHAM, HAIK, SCHNOBRICH , KAUFMAN & DOTY, LTD. <br /> Minnesota Pollution Control Agency <br /> March 6 , 1980 <br /> there is no environmental justification for building an inter- <br /> ceptor that allows for the continuation of the taking of efflu- <br /> ent from one watershed and then transporting it across another <br /> watershed with the resulting adverse environmental effect on <br /> the second watershed area. Mayor Van Nest then showed how <br /> the effluent could be taken from the plant and pumped a short <br /> distance across the watershed boundary so that it could be <br /> discharged into the Crow River Watershed and into Pioneer Creek, <br /> then through a massive marsh system� into the Crow River and <br /> then eventually into the Mississippi River some 40 miles away. <br /> He stated that such a natural method of purification is far <br /> superior to pumping that small amount of effluent in a new <br /> five mile pipe across rural Orono , and then 30 or 40 miles <br /> all the way to the Blue Lake plant on the Minnesota River where <br /> there are presently problems in the handling of the existing <br /> discharge of effluent from the metropolitan area. The mayor <br /> stated it was crazy from an environmental and a taxpayer ' s <br /> point of view to spend $1 . 5 million to put a pipe in in such <br /> a way when the other alternatives are less costly and have <br /> less of an adverse effect on the environment. <br /> Alan Larsen indicated that Maple Plain and the MWCC can apply <br /> now for infiltration monies to help solve that problem now. <br /> He stated that the I � I analysis will be completed to determine <br /> what the flow figures will be once the infiltration problem <br /> is solved. Mayor Van Nest stated that once you solve the I <br /> � I problem, you do not even need to spend $578 ,000 to make <br /> the plant larger to handle the prior gallonage which will now <br /> be reduced. He indicated that the present report shows that <br /> you can spend just $30 , 000 for removing the phospherous which <br /> would solve the problem at a far less cost to society. Mayor <br /> Van Nest noted that the present plant is surrounded with agri- <br /> cultural land as is the entire Maple Plain area and that it <br /> does make sense to use an on-land spray irrigation system. <br /> The mayor explained that the 201 plan compared the cost of <br /> upgrading the plant to the cost of land application and then <br /> decided that land application was too costly. Thereafter the <br /> plan compared the cost of plant upgrading so that there would <br /> only be 1 . 0 milligram per liter discharge versus the cost of <br /> installing the interceptor , and then the plan stated that such <br /> a discharge was insignificant yet somehow from that conclusion <br /> the plan then stated that when compared to the cost of the <br /> interceptor , the interceptor should be installed. It is <br />
