17 <br /> 1 Vice-Chair Hamilton asked about the impact of climate change on these systems. She <br /> 2 asked, as there are more flood events, how do these community and individual systems work <br /> 3 when there is more water in the ground? <br /> 4 Tony Whitaker said the state allows counties to have local rules for the time being. He <br /> 5 said Orange County has historically been looked to as a leader in the state on on-site <br /> 6 wastewater regulation. The current rules give the county the ability to have extra requirements <br /> 7 that can prevent water intrusion. However, dispersal fields don't work as well when they are <br /> 8 saturated from rainfall, of course, and some community systems are required to have additional <br /> 9 storage capacity in the tanks and not disperse water when it's extraordinarily wet, but disperse it <br /> 10 later. He said another mitigation effort would be to keep these wastewater systems out of <br /> 11 floodplains and near-term floodplains. He acknowledged that there isn't a great static answer to <br /> 12 what a floodplain is because it is always changing. He said municipal treatment plants are <br /> 13 facing the same questions, so it is not unique to community septic systems. <br /> 14 Vice-Chair Hamilton acknowledged that this is an issue with different types of systems <br /> 15 but pointed out that there is a difference between systems in who mitigates and pays for issues. <br /> 16 Commissioner Fowler thanked Tony Whitaker for his presentation. <br /> 17 <br /> 18 The Board recessed for a break at 10:11 AM. <br /> 19 <br /> 20 The Board reconvened at 10:23 a.m. <br /> 21 <br /> 22 2.
