Reference the attached stamped site plan. The septic system was serviced on 5/17/2023, where it was determined that pumping would not be necessary. A site visit was conducted by this office,no signs of failure were observed. THE AUTHORIZATION NOTICE FOR CONNECTION TO A TEMPORARY HARDSHIP DWELLING TO THE EXISTING ONSITE SYSTEM IS APPROVED.

THE SEPTIC TANK SHOULD BE PUMPED AND INSPECTED by a licensed septic tank pumping service approximately EVERY FIVE(5)YEARS. The septic tank is a reservoir for the solid materials in the sewage waste stream. Excessive accumulation of these solid materials in the septic tank can cause the solids to wash out of the tank and into the drainfield. This can cause irreversible damage to the drainfield and can eventually lead to a system failure. THE APPROVED SEPTIC SYSTEM AREA MUST BE PROTECTED from any vehicular traffic,livestock and farming activities. Other activities such as logging, excavating or filling, driveway placement or any similar activities may also damage the soil in the area and adversely affect the septic system approval. The areas of the initial septic system and the future repair system must both be protected. OBSERVE ALL SETBACKS AND SEPARATION DISTANCES as required by the DEQ rules. The well placement is especially critical and must be located at least one-hundred(100)feet from the approved initial and replacement DRAINFIELD areas.
