(3 1 Non-Compliant System: System may or may not meet current City standards for design, v construction, or location, but is failing to properly treat and dispose of the current input; and any system with less than three feet of vertical separation between the bottom of the drainfield and the saturated soil level. (The saturated soil level is [(] or is not [ ] identified under this septic system. If the saturated soil level is not identified, this classification is subject to revision.)

TI-IIS IS NOT A PERMIT. This is a design approval form which must accompany the site plan. A permit must be issued to a licensed septic contractor prior to installation. A list of currently licensed septic contractors is enclosed. NOTICE TO INSTALLERS: Any changes to the approved plans and specs must have prior approval of the Inspector (473-7357). Call for inspections 24 hours in advance. ALL DRAINFIELD AREAS MUST BE FENCED OFF prior to building site excavation and fencing must remain in place until final site grading. Approval to pour footings will not be granted until the Inspections Department has verified that primary and alternate sites are adequately protected. NO VEHICULAR TRAFFIC OF ANY KIND (cars, trucks, earth moving equipment, etc.) is allowed within 20' of tested drainfield sites either before or after system construction. Compaction of these areas could render them unusable prohibiting the timely completion and or limiting the long term use of the property. A site copy will be available at the City Offices for the septic contractor. CITY OP ORON• BY / i' i / %I/J Stephen •c man, On-site Systems Manager TELEPHONE-473-7357• FAX-473-0510 J� I.
