Co., MN <br /> A site evaluation was completed for a new system for this property due to the existing <br /> system being non-compliant. The only areas available for a new system were either fill, <br /> excavated or compacted soils & are not suitable for a new system. <br /> The proposal is to remove the existing mound from the upslope edge of the rock bed to <br /> the downslope toe. This must be completed with minimum trave over the site. The <br /> rockbed is ponding & will need to be exposed & the eflluent pumped out. The trees on <br /> the mound will need to be removed. The new sand will be placed with the bottom of the <br /> rock bed at elev.113.0. <br /> The existing tanks may be used upon a T�nk Integrity report passing. <br /> The supply line will need approximate(y 60' replaced to manifold at the east end of the <br /> rockbed. <br /> The manifotd and supply line pipe must have back drainage to the pumping chamber. <br /> The distribution pipes shall h�ve their ends capped. Be sure the rock and sand fill <br /> material are clean. The sod layer below the entire mou�ded area must be turned over, <br /> just break up the sod, be sure not to over work. <br /> If the tanks have less than 2' of cover, the lids, risers & maintenance hole covers must <br /> be insulated to a value of R10. <br /> An effluent screen will be needed at the outlet of the 2nd tank, which needs ta be <br /> cleaned 2 times a year if a garbage disposal is installed. <br /> 1 <br />
