10. <br />11. <br />12. <br />14, <br />15, <br />17. <br />The new Chapter 7080 clearly defines what is required of a contractor for a site <br />evaluation and an ISTS design. To avoid redundancy, our code has been amended to <br />require three soil borings per site and two percolation tests per site. Chapter 7080 does <br />not specify a number of borings or percolation tests required for an ISTS design. <br />The State recommends that all water softener recharge water be rerouted out of all ISTS <br />An ISTS is not designed to handle this water and early failure of the ISTS could result. <br />The current Orono septic code states that mound systems cannot be constructed on <br />greater than 6% slope. Chapter 7080 states that there is no restriction on slope for a <br />mound system and that at-grade systems cannot be placed on slopes greater than 25%. <br />Orono septic code is now amended to allow mound systems and at-grade systems on <br />slopes up to 12% depending on the soil texture and percolation rates. <br />Homeowners now will be required to keep a diagram showing location of the sewage <br />tank(s), distribution box(es), soil treatment area, pump station, sewer line, water well and <br />the location of the septic alarm in the residence on the property at all times. <br />All new holding tank installations will require review by the City Council. <br />The ISTS requirements for the ”RS" Zoning District (Big Island) have been clearly stated. <br />The language takes in the fact the uniqueness of Big Island. This should give property <br />owners flexibility in determining the proper ISTS for the property. <br />All septic tanks are required to be pumped through the manhole cover. The pumper must <br />also determine tank integrity and include that information in the report to the City. The <br />report must be mailed within seven days of the pumpout. <br />The date for replacement of all septic systems to be upgraded has changed. All non- <br />compliant septic systems located in the shoreland district will need to be replaced by <br />December 31, 2007. All non-compliant septic systems located outside of the shoreland <br />district will need to be replaced by December 31, 2010. <br />Page 2 of 2
