A copy of the DEQ <br /> setback requirements is available in our office and online at <br /> http:l/www.oregon.gov/deq/Residential/Pages/Onsite.aspx under Rules: <br /> Division 71: Table 1. <br /> • <br /> MAINTAIN PERMANENT ACCESS to septic tank for pumping and <br /> service. The septic tank should be pumped and inspected by a <br /> licensed septic tank service before sludge and scum <br /> accumulations reach 30% of the tank liquid operating volume. <br /> Pumping every 3 to 5 years is an average interval. The septic tank <br /> is a reservoir for the solid materials in the sewage waste stream. <br /> Excessive accumulation of these solid materials in the septic tank will <br /> cause the solids to wash out of the tank and into the drainfield. This will <br /> cause irreversible damage to the drainfield and will eventually lead to a - <br /> system failure. <br /> THE ATTACHED SEPTIC TANK ABANDONMENT FORM MUST BE <br /> COMPLETED AND RETURNED TO OUR OFFICE. The septic system <br /> installer must complete and sign the form and attach a copy of the <br /> receipt from the septic tank pumping service for pumping the tank. <br /> THE APPROVED SEPTIC SYSTEM AREA MUST BE PROTECTED from <br /> any vehicular traffic or other sources of soil compaction. Activities such <br /> as excavating or filling, driveway placement, paving or any similar <br /> alteration of the natural soil conditions will adversely affect septic system <br /> function and lead to premature system failure. The area must not be <br /> subjected to excessive saturation due to artificial drainage of ground <br /> surfaces, driveways, building downspouts or other.sources. The areas of <br /> the initial septic system..and the future repair system must both be <br /> . _protected.* <br />
