Box 66 Orono, MN 55356 Crystal Bay, MN 55323•0066 Richard Perkins November 14, 1996 1699 North Farm Rd. Long Lake, MN 55356 Dear Mr. Perkins: The purpose of this letter is to clarify the condition of your septic system. The septic system at 1699 North Farm Rd. was installed in 1979 and routine inspections were performed five times since then. The purpose of these inspections was to identify whether the system was accepting the entire sewage output from the residence and to assure that the system was being maintained properly. The Minnesota Department of Natural Resources (DNR) mandated and the City adopted new regulations for properties within 1000 feet of protected lakes in 1992 requiring that septic systems meet a three foot separation between the drainfield and the seasonal water table. Your residence is within 1000 feet of Long Lake but because soil testing performed prior to the installation of your septic system indicated that the drainfield met a three foot separation from the seasonally high water table, you were issued a permit to add on to your residence without being required to upgrade the septic system. However, due to a portion of your future drainfield site being driven over with construction equipment, the Building Inspector asked me to determine whether the site was damaged. During the inspection I discovered that the existing drainfield site has no separation from the water table and is non-compliant. The future site was slightly excavated, but due to dry conditions this year, no significant damage was done to the alternate site. The City municipal code requires that the non-compliant septic system be upgraded within two years of being identified or in conjunction with any permit issued for the property. As we allowed construction to begin without an agreement that the septic system be replaced, you will not be required to upgrade the system at this time. However, repair of the drainfield will now be required by 12/31/98 or when a permit is required for the property,whichever comes first. Please contact me at the City offices if you have any questions. Sincerely, �� f Step n Weckman On-Site Systems Manager Telephone (612) 473-7357 • FAX 473-0510
