They met with Bobby Poarch, the ORC, on site. The ORC was able to provide all records requested and explained how the system operates. After reviewing records and all components of the system, it was determined that is is compliant with the permit. Infiltration is working well for this system now, and they have not needed to utilize the Oak Island Recreational Fields yet. They had to remove grass clippings/vegetation recently from the infiltration basins. Maps were available of all GW MW on the golf course.

The Oak Island Recreation Fields are not being used because they are not currently needed with the demand. There is no 5 day upset pond because the plant has the ability to send any upset water to the West Brunswick WWTF if needed. Upset water that occurs now is being recirculated back through the plant to be treated again. Infiltration is working well, ORC states they had to remove grass clippings/vegetation and clean out recently. Valves automatically shut off when FB gets to 11 ". ORC then has to reroute to West Brunswick WWTF. Discussed sprinklers being marked purple and whether they function at Oak Island Recreational Fields in case this area is needed it the future. It is not currently being utilized. Turbidity meter functions bV using a laser for measurements. It read 0.04 while on site. Page 7 of 7
