Boz 66 Orono, MN 55356 Crystal Bay, MN 55323.0066 To: The Current Owner of Address City Ordinance requires that onsite sewage treatment systems in Orono be inspected on a periodic basis. The onsite sewage treatment system at the above address has been inspected and the following is known about the system. A sketch of the known components of the system is available for most properties at the Orono City Hall. Imminent Public Health Threat Yes No If yes, please contact the Onsite Systems Manager at 952-249-4626 within 10 days of receipt of this notice. The septic system must be brought into compliance within 90 days. Failure to do so will result in referral to the City Attorney for legal action. System Identified as Non-Compliant Yes No If yes, system must be brought into compliance by: December 31,2007 December 31, 2010 Other Septic Tank(s ump out Needed Yes No The City recommends the septic tank(s) and/or lift tank be serviced and pumped out every three ears. City records indicate the tank(s) were last pumped out on The tank(s) should be cleaned through the manhole and not through the inspection pipes, this allows for proper cleaning.

Box 66 Orono, MN 55356 Crystal Bay, MN 55323-0066 August 13, 1998 Patrick Brazil Busse Construction 2325 East 75th Street Inver Grove Heights, MN 55076 Dear Mr. Brazil: As per your agreement with Greg Gappa, we have performed a site evaluation and fenced off drainfield sites at 425 Turnham Road. The City Council required that a future drainfield site be identified prior to the issuance•of a land alteration permit. Two drainfield sites were identified due to the existing system being non-compliant, and requiring repair in the near future. The following report includes a site plan,soil boring records, and septic system design specifications. The report required ten hours of staff time to complete at $30 per hour for a total of$300. Since the drainfield sites needed to be fenced off to prevent damage, an additional$230 is included for fence posts and fencing. The$530 must be paid in addition to $75 before the land alteration permit can be issued. Please contact me at the City Offices if you have any questions.
