Permit Number: 555-19-001532-PRMT Date:March 28,2019 Completed By: CRH Project Address: 5295 St Louis Road NE,Gervais 052W20 00300 SEPTIC SYSTEM MAJOR ALTERATION Rural Areas Consideration for Standard System HEADER PIPE between Distribution Boxes and drainfield trench must measure a minimum of 4 feet, must be installed level, and bedded on undisturbed earth. OBSERVE ALL SETBACKS AND SEPARATION DISTANCES as required by the Department of Environmental Quality rules. A copy of the DEQ setback requirements is available in our office and online at http://www.oregon.govideq/Residential/Pages/Onsite.asox under Rules: Division 71: Table 1. THE ATTACHED SEPTIC TANK ABANDONMENT FORM MUST BE COMPLETED AND RETURNED TO OUR OFFICE. The septic system installer must complete and sign the form and attach a copy of the receipt from the septic tank pumping service for pumping the tank. THE APPROVED SEPTIC SYSTEM AREA MUST BE PROTECTED from any vehicular traffic, livestock and farming activities. Other activities such as excavating or filling, driveway placement, paving or other similar activities that alter the natural soil conditions will adversely affect the soil and the septic system function and lead to premature system failure. The area must not be subjected to excessive saturation due to artificial drainage of ground surfaces, driveways, building downspouts or other sources. The areas of the initial septic system and the future repair system must both be protected. MAINTAIN PERMANENT ACCESS to septic tank for pumping and service. The septic tank should be pumped and inspected by a licensed septic tank pumping service before sludge and scum accumulations reach 30% of the tank liquid operating volume. Pumping every 3 to 5 years is an average interval. 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 will cause the solids to wash out of the tank and into the drainfield. This will cause irreversible damage to the drainfield and will eventually lead to a system failure.
