caus<* seweag^ to flow into th^ lake. Concecn for dredging those <br />because of the primary access from the West Arm/Spring Park area. <br />The interceptor line in question is the old interceptor that was <br />originally put in by Orono back the the 60*s and taken over by <br />Metro Waste Control Commission in the 70*s. As you may recall <br />the Metro Waste Control Commission will be turning this back <br />because it will be used for local sewage whtn the new interceptor <br />is completed. Currently the City staff is exploring the easement <br />that it has through the DNR for th«» placement of that line <br />together with what rights or responsibilities the City has to <br />accept the line. It is estimated that a permanent fix to either <br />replace the line with a deeper line or eliminate it by use of a <br />lift station may cost between $25,000 and $50,000. Staff will <br />keep Council abreast as this issue develops. Included in the <br />overall dredging program by Hennepin County are the North Arm, <br />Noerenberg, Forest Lake and Tanager Lake channels. There are <br />underground sewer lines in all but the Noerenberg channel. Staff <br />is monitoring the impact to the sewer lines of the dredging. <br />\
