Site evaluator will perform percolation tests in the <br /> remaining sand layer prior to reconstruction of the system. <br /> If the resulting percolation rate is slower than 5 minutes <br /> per inch, then further analysis of the sand layer will be <br /> required prior to system reconstruction. <br /> 3 . Installer will replace the 6" layer of sand and the rock <br /> bed, using new materials conforming to minimum requirements <br /> of Chapter 7080. <br /> 4. Drainfield rock must be covered with either a permeable <br /> synthetic fabric (preferred) or a 4" layer of hay or straw <br /> covered with untreated building paper. <br /> 5. Installer shall place sandy loam soil on the drainfield rock <br /> to a depth of 1' in the center of the rock bed and 6" at the <br /> boundaries of the rock bed. <br /> 6 . Installer shall place approximately 6" of topsoil over the <br /> mound to bring the system back to grade. <br /> 7 . All repair work and materials must meet the minimum <br /> standards of Chapter 7080. <br /> In order for the installer to work on this system, the mound should <br /> not be dosed with effluent for a 2 to 3 week period of time to allow <br /> the system and surrounding area to dry sufficiently. This will <br /> require that the septic tanks be monitored and pumped on a regular <br /> basis during that time. I understand this dry-up period is underway. <br /> The installer must obtain a repair permit for this system prior to <br /> commencing repairs. The permit is $50.50. <br /> The installer shall coordinate with the City Inspector and the Site <br /> Evaluator to ensure timely inspection and testing as required. <br /> Nothing in this letter should be construed as an opinion or <br /> determination as to which parties, if any, are responsible for the <br /> failure of the system. <br /> Please feel free to contact me or Septic System Inspector Steve <br /> Weckman at 473-7357 if you have any questions. <br /> Sincerely, <br /> �y� /� i.� � � � <br /> l i'-l' "�' --� �� f'�. lJ��l���t"`��,/.1�,� � <br /> Michael P.
