7 <br />This group was formed under a directive from the Orange County Board of Health <br />to provide input to the three main components of the expansion to include gravity <br />flow septic systems in the WIMP framework The components are education, <br />homeowner incentives and re- inspections. Outlines of the history of the current <br />WTMP initiatives and the expansion were presented to the committee for <br />consideration and guidance. Rosie Summers and Ron Holdway facilitated the <br />discussions: <br />The impetus to explore the expansion came from a joint meeting of the Board of <br />Commissioners and the OWASA Board and an ensuing meeting of the Board of <br />Health. All three boards recognize that existing failures rates (8 -10 %) are not <br />likely to improve without action and that centralized wastewater disposal will not <br />be a repair option in many areas of the county in the foreseeable future. Failures <br />are caused by a variety of factors, most notably poor soils conditions, wetter <br />seasons and individual household water habits. To prevent premature failures, <br />long term management must be implemented to extend the usable lives of systems <br />and preserve repair strategies. Since there are no programs in place in North <br />Carolina which include management for all on -site systems, staff looked at <br />examples from several other localities nationwide with a full management <br />approach in place or under consideration. These localities included Georgetown <br />Divide in California, Ten Towns jurisdiction in New Jersey, Cuyahoga County in <br />• Ohio and Jamestown, Rhode Island. EPA recommendations were also reviewed <br />for reference and applicability as well as information from state level agencies in <br />North Carolina, Michigan, and Hawaii. <br />After discussion by the committee, the proposal will be presented to the Board of <br />Health for action pursuant to NCGS § 130A -39. If approved, the proposal` will then <br />go to the BOCC for funding consideration. Staff would like for the BOCC to have <br />the proposal for this consideration at their December retreat. In the meantime, <br />staff will explore the possibility of preparing maps of recent septic system repairs <br />both by township and in the OWASA service area. <br />EDUCATION <br />Current Efforts: <br />The educational efforts in use in the WIMP area today are by individual contact, <br />printed material given at the time of occupancy of new homes, other brochures for <br />existing homes, and the Internet site. Mass mailings are also used, but are not <br />routine. The emphases of the educational efforts are to promote and protect public <br />health, preserve water resources, and extend the average life of septic systems in <br />Orange County. One of the main facts that must be continually emphasized in this <br />effort is that the systems must be viewed by all parties—homeowners, government <br />• and private sector contractors —as a perpetual utility which must function for the <br />life of the house, not just as a stopgap until public sewer arrives. <br />Page 2 of 12 <br />
