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