for the worSt-case situation. They anticipate it will be even more efflclen~ than what Is being proposeD, The proposal will meet all crlterlalestabllshed and wl)) require no cost to the City. Mr. Jankowskl then explained that the City's storm sewer Is located south ofrthe railroad tracks but north of Highway 10. It is In the City's p)~an to extend that 48-Inch storm sewer pipe north of the ral]road~tracks some day. He suggested that consideration De given to allowl[ng WMM! to connect to the City's storm sewer line, but have tbe~ add to that line Dy extending that pipe north from its exlst]ng ]ooatlon under the railroad tracks as part of the City's payment, i He suggested the line should go as far north as McKinley Street where It wl]] be needed If that road Improvement is approved, Attorney Goodrich aisc suggested video taping the pipeline prior to the dlscharge from WMMI as a baseline on the condition of the pipe. ~bC~_QJJ~ - stated he was agreeable to video taping and documenting the condition of the line prior to the start of the project. He has also visited a slte In Indlannapo]ls which has baslcal]y~ the same system and Is operating unaer an NPDES permit. It Is an acceptable technology, and this wl]] be one of the flrst systems on line In the State. Mr. Otter then noted the monitoring consists Of samples taken on a scheduled basis -- ~al]y on the start-up, probably quarterly when the system is fully functional, whatever Is dlcated by the permit. In addition, It Is unlikely there will be a failure tn the system where the VOCs would unknowl~g.ly be discharged to the river, as there are a number of malfunction devices and shutdowns to prevent that from happening. Mr. Otte~ - also stated he is willing to finance the cost of construct!lng the City's 48-inch pipe from its existing location to the north si~e of the railroad tracks to avol~ duplication. D~u~ Fountain. 15253 152nU Avenue NW - In the event of a summer ~ownpour and the storm sewer could not take this treated water, would WMMI be closing down the process? Mr. Otter stated the system would automatically shut down if two-thirds of the storm sewer pipe is flow, and the system wou]d have to be manually put back on line. Mr. FQuDtain - stated Mr. Otter mentioned diverting water to Sunfish L~ke from another area, asking what wildlife area would De affected. Mr. Otter explained the other area of concern is the wildlife area across from Sunfish Lake. There could De a draw-down such that the wild]ire area could dry up and ~isappear. Their concern iS to keep that area moist an~ wet so the wetland would De maintained. The equipment is in p]ace to monitor other wet]ands as we]] so they wi]] know if something occurs. Mr. Hart)ey suggested if it so chooses, the Council should direct the City Attorney to prepare an agreement consistent w]th the term~ discussed this evening between the City of Ramsey. and WMM!.
