Future changes in sewage treatment ISTS administration are expected to be refinements of the <br />existing policies and ordinances, as well as changes promulgated at the State level. <br />The 1978 adoption of Ordinances 210 and 212 for the first time established detailed standards for <br />use and maintenance of both on-site systems and discharge into the municipal system. This new <br />emphasis will continue to need rcfincmcnt-as-it affects other ordinances-of the City. Citv’ code and <br />State rule revisions since 1978 have resulted in regulations which enhance the ability of ISTS to be <br />a permanent sewage treatment and disposal option for rural Orono. <br />A general reeodification of all City ordinances is in process and is necessary to completely integrate <br />these ordinances with other sections of the Municipal €odc. In the interim, the On-Site Code is <br />applicable by itself and has affected theFlood Plain ordinance (adopted on I0 -26-78) and the eurrent <br />drafts of a revised subdivision ordinance; <br />Office procedures, records and administration are also continuously being refined as the On-Site <br />Program matures enters its third decade. Educational materials have been prepared and updated, and <br />Permit forms and design manuals are available, ftrecord systems are being modified after two years <br />experience have been computerized. New-engineering procedures have been developed for design <br />standards,'review and inspcction-of-ncw sewer laterals and their effect on the-cxisting system. <br />A primary goal of the On-Site Program is to keep abreast of the ever-changing State regulations and <br />ensure that the Citv takes advantage of new technologies as they become proven. However. Orono <br />will not become a testing ground for such new technologies without establishing strict parameters <br />for monitoring and mitigation, to ensure that no new home is left without ISTS options should an <br />unproven technology fail. <br />In addition to ISTS regulations, the Citv has adopted regulations to prohibit sump pump discharge <br />to the municipal sewer system. Orono's extensive lakeshore area sewer system has experienced <br />inflow and infiltration (1 & 11 problems which have resulted in excessive incurred costs for sewage <br />treatment. Reduction of 1 & I bv eliminating sump pump discharges is one means of reducing the <br />City’s sewer system operating costs. <br />CM? 5-31
