on 2>acre lots could be sustainable without sewers in the long term, pockets of <br />existing development on smaller lots would eventually have to be served with <br />sewer. <br />This fact was mad e clear in Orono's 1980 Comprehensive Plan, in which <br />five historically high-density existing neighborhoods were identified as critical. <br />During the period 1980-1992. each of these neighborhoods were provided with <br />municipal sewer. <br />The currently proposed MUSA additions are similarly a result of Orono s <br />comprehensive approach to septic systems management. Rather than using these <br />older pockets of pre-existing dense development as an excuse to sewer the entire <br />City and compromise Lake Minnetonka, Orono chooses to provide sewers only to <br />those existing neighborhoods where septic systems are not a viable long-term <br />solution for sewage treatment and disposal. Further, Orono chooses to not provide <br />municipal sewer to accomodate new development in the rural area, which comprises <br />the majority of the Orono's remaining developable land. <br />2. Ordinances and Management Program <br />Orono’s On-site Sewage Treatment Systems ordinances including technical <br />standards and the management program are included in the appendices. The City <br />has adopted by ordinance MPCA’s Chapter 7080 regulations plus some additional <br />more stringent technical requirements for certain types of systems (Section 12.30, <br />Subd. 5). <br />"Code" and "Conforming” systems are inspected biennially. "Nonconforming" <br />systems not meeting the 3-foot water table separation must be upgraded to a <br />conforming status by the end of the second year following date of initial non­ <br />conformity notification (Subd. 8(B)(4a)). "Failing" systems must be repaired <br />within 90 days/1 year (Subd. 8(B)(4b)). <br />A complete record of the design and location of of each existing septic system is <br />kept on file, and maintenance records for each system are updated annually (see <br />Inventory Card sample in Appendix). <br />Permits are required for system repair/replacement and all new construction. <br />Contractors and site evaluators/designers are currently licensed by the City, <br />although City licensing wUl be discontinued when State licensing takes effect in <br />1996. <br />All inspections of new and existing systems are completed by City inspectors <br />certified by the MPCA. The position of On-Site Systems Manager is currently held <br />by Steven Weekman.
