Conditions observed during this site evaluation indicate <br /> ENGINEERING that the area around the evaluated test holes is not capable of supporting <br /> a Standard septic system due to the following limitations: <br /> ENVIRONMENTAL <br /> SERVICES Limited space <br /> OPERATIONS There is not sufficient area for a standard repair system that meets <br /> PARKS setbacks to the stream/pond and property lines. <br /> PLANNING Specific Requirements <br /> SURVEY A pressurized seepage bed system is required in order to meet <br /> setbacks. For a 3 bedroom home, a 500 square foot minimum bed is <br /> required per OAR 340-071-0275(4)(d). This is a reasonable repair, <br /> under OAR 340-071-0215; the soils do not meet the definition of soil <br /> with rapid permeability per OAR 340-71-0100(148) however in the <br /> opinion of the agent this will not create a public health hazard. <br /> Specific sizing and site placement details can be found on the attached <br /> Soil Notes/Field Worksheet. <br /> The owner of a Pressurized Distribution System must maintain a service <br /> contract with a licensed and certified professional to service and maintain <br /> the onsite system. A service contract must be entered into before a <br /> certificate of satisfactory completion is issued and must be maintained until <br /> 5155 Silverton Road NE•Salem,OR 97305-3802• www.co.marion.or.us/PW <br /> Printed on recycled paper• Reduce—Reuse—Recycle-Recover <br />
