for the ~orst-¢ase situation. They anticipate it will be even more eff]¢l~n~ than what Is being proposed. The proposal will meet all criterion, e~tabllshed and will require no cost to the City. Mr. JankOwskl then explained that the City's storm sewer Is located south off, the railroad tracks but north of Highway 10. It Is In the City's pil&n' to extend that 48-Inch storm sewer pipe north of the railroad[tracks some day. He suggested that consideration be given to all OW~ng WMMI to connect to the City's storm sewer line, but have them add to that line by extending that pipe north from Its exlstlngl location under the railroad tracks as part of the City's payment,.~ He suggested the line should go as far north as McKlnley Street w~ere It wlll be needed if that road Improvement Is approve~ Attorney Goodrich also suggested video taping the pipellnei~prlor to the discharge from WMMI as a baseline on the condltIo~ of the pipe. I~ -istated he was agreeable to vldeo taplng and documentIng the condition of the line prior to the start of the proJect.i He has also visited a site In IndJannapo]ls which has basically the same system and Is operating under an NPDES permit. It is aniacceptable technology, and this will be one of the first systems ~n !lne In the State. Mr. Otter then noted the monitoring consistsl~of'samples taken on a scheduled basis -- dally on the start-up; p~obably quarterly when the system Is fully functional, whatever[ts dlcate~ by the permit. In addition, It Is unlikely there will be a failure In the system where the VOCs wou]d unknowln$ly.~e discharged to the river, as there are a number of malfunction'devices and shutdowns to prevent that from happening. ~ - also stated he is willing to finance the cost of constructing the Clty's 48-inch pipe from its exlsting location to the north side of the railroad tracks to avoid duplication. Dou~ Fou~t&l~n. ~5253 ~52nd Avenue NW - In the event of a summer ~ownP°u~iand the storm sewer could not take this treated water, would WMMI be closing down the process? Mr. Otter stated the system w~uld automatically shut down if two-thirds of the storm sewer pl~e~ i~s flow, and the system would have to be manually put back on l~tne. Mr. Fountain - stated Mr. Otter mentioned diverting water to Sunfish'~akel from another area, asking what wildlife area would be affected.~ Mr. Otter explained the other area of concern is the w]ldllfe area across from Sunfish Lake. There could be a draw-down such tha~ the wildlife area could dry up and disappear. Their concernil~ to keep that area molst and wet so the wetland would be maintained. The equipment Is In place to monitor other wetlands as ,~e]l so they wi]] know if something occurs. Mr. Hartley suggested if it so chooses, the Council should direct the City Attorney to prepare an agreement consistent with the terms discussed' this evening Detween the City of Ramsey and WMMI.
