There are a few items that need to be addressed before I can <br /> BUILDING approve your application: <br /> INSPECTION <br /> EMERGENCY 1. The drop box's lid was cracked into three pieces, and the box has <br /> MANAGEMENT been compromised by tree roots. This drop box must be replaced. The <br /> second box was not exposed for inspection, however, it will need to be <br /> ENGINEERING exposed at the time of the inspection of the replacement septic tank and <br /> drop to ensure it is in working condition. The box(es) can be replaced <br /> ENVIRONMENTAL under the same minor repair permit as the tank. <br /> SERVICES 2. There was a significant amount of sludge/solids accumulated in the <br /> exposed drop box, approximately 6". This is likely due to infrequent <br /> OPERATIONS pumping in the past, use of septic tank additives that inhibit settling of <br /> PARKS solids, or water softener waste plumbed to the septic tank (these wastes <br /> contain high salt amounts which cause solids to float and reach the <br /> PLANNING drainfield). This highly excessive amount of solids will inhibit the function of <br /> the drainfield and cause the system to fail. Per OAR 340-071-0205(4)(c), I <br /> SURVEY cannot authorize the use of the system in this condition. It may be possible <br /> to pump out the solids and hydro jet the lines to remove the•solids. Either <br /> this will need to be done, or the drainfield will need to be replaced under a <br /> major repair permit. <br /> Please let me know how you wish to proceed. If you plan to pump and <br /> hydro jet the lines, have this done by a DEQ licensed pumper and contact <br /> me for reinspection. Alternately, If you wish to pursue a major repair <br /> permit, please: <br /> 1. Dig two or more test pits in the location you wish to install a new <br /> drainfield <br /> 2. Update your plot plan with the location of the test pits and include <br /> the dimensions from the pits to property lines.
