She <br />said existing development issues will be handled in phase two. She hopes the jurisdictions will <br />come out of this with a toolbox of things that can be done. <br />Chair Jacobs asked if there has been any discussion about storm water credits or <br />pollution credits. <br />Pam Hemminger said this is on the table as part of the nutrient credit program. She <br />said the level of the credits would have to be approved by multiple entities. <br />Chair Jacobs asked what happens to monitoring at the end of the 4 or 5 year period. <br />Pam Hemminger said the Division of Water Resources (DWR) thought 4 -5 years would <br />be sufficient for monitoring, and they are aware of how expensive the monitoring is. She said <br />she does not know what will happen in the future, and it will depend on the answers that are <br />given by the current monitoring. <br />Commissioner McKee referred to Pam Hemminger's earlier comment about the design <br />of the lake being the reason for the issues in the upper end. He said his property contains two <br />ponds, and one stays clear all of the time; but the second shallower pond is almost never clear <br />due to algae blooms. <br />Commissioner Price asked about the differentiation between farm and residential runoff. <br />Pam Hemminger said the information from the monitoring will show where problems <br />exist, and then the department will work out strategies depending on the lay of the land and <br />what is out there. She said best management practices will have to be put in place. She noted <br />that there are new development rules, and several areas are being moved off of septic <br />systems, which will build up credits. <br />Pam Hemminger said there are only two small natural lakes in the state of North <br />Carolina and all of the others are man -made. She said these are not made deep enough, and <br />this is a problem all over the state. <br />3. Orange Well Net Update <br />Tom Davis reviewed the following background information and PowerPoint slides: <br />The Department of Environment, Agriculture, Parks and Recreation's (DEAPR) groundwater <br />observation well network, Orange Well Net (OWN) uses a combination of bedrock and regolith <br />wells spread across the main types of bedrock geology present in Orange County. Regolith <br />wells, which measure groundwater levels in the unconsolidated material present above bedrock <br />in the subsurface, monitor natural stresses on the quantity of groundwater available in storage <br />which are caused by variations in climatic conditions. Bedrock wells monitor changes in <br />groundwater levels in the bedrock across the County. <br />WELL NET PowerPoint <br />• Orange Well Net Update <br />• Orange County <br />• Department of Environment, Agriculture, <br />• Parks and Recreation <br />• Orange Well Net Goals <br />A. Primary Goal: <br />• Monitor natural stresses on the quantity of groundwater available in storage caused by <br />variations in climatic conditions. <br />• Network should mainly utilize climatic effects (regolith) observation wells to monitor <br />groundwater storage. <br />
