To: Marino Vasquez <br /> From: Robert Goodwin, REHS; Aidan Bammes EHST <br /> RE: Alteration Permit at 9929 Crosby Rd NE <br /> July 19, 2021 <br /> -Page 3 <br /> Alternative systems include SAND FILTERS, RECIRCULATING GRAVEL FILTERS, <br /> and ALTERNATIVE TREATMENT TECHNOLOGIES. Alternative systems are installed <br /> where soil, drainage, water table levels, or space limitations do not allow for a standard <br /> system installation. The unit pre-treats the septic tank effluent before it is discharged <br /> into the ground. The owner of an ATT system must maintain a-service contract with a <br /> licensed and certified professional to service and maintain the onsite system. A service <br /> contract must be entered into before the system is installed and must be maintained <br /> until the system is decommissioned. <br /> AN EFFLUENT LIFT PUMP MAY BE REQUIRED to install the septic system disposal <br /> field in the approved area and at the required depth. Detailed instructions for dosing _ <br /> tank/effluent pump installations are available in our office. The electrical wiring to the <br /> pump and alarm must be installed in accordance with the appropriate Electrical Code. <br /> The electrical work must be done under a Marion County Electrical Permit and must be <br /> inspected and approved by a Marion County Electrical Inspector. The work must be left <br /> uncovered and accessible for inspection. The electrical inspection includes the <br /> n alarminthe dosingtank, the wiringinthe trench and the <br /> connections to the pump and <br /> connections in the structure. <br /> THE APPROVED SEPTIC SYSTEM AREA MUST BE PROTECTED from any vehicular <br /> traffic and livestock. Other activities such as excavating or filling, driveway placement, <br /> paving or other similar activities that alter the natural soil conditions will adversely affect <br /> the soil and the septic system function and lead to premature system failure. The area <br /> must not be subjected to excessive saturation due to artificial drainage of ground <br /> surfaces, driveways, building downspouts or other sources. The areas of the initial <br /> septic system and the future repair system must both be protected. <br /> 5155 Silverton Road NE•Salem,OR 97305-3802• www.co.marion.or.us <br /> Printed on recycled paper• Reduce—Reuse—Recycle-Recover <br />
