| Objectives | The Discharger discharges wastewater from a geothermal space heating system into a surface drain which in turn discharges to Wolf Creek, a water of the United States. Hot water, (115 degree F), from the geothermal well, which housed in a wooden shed to the southeast of the front entrance, enters a heat exchanger and is then discharged to a sub grade 4-inch Schedule 40 PVC pipe which passes under Hot Springs Road and eventually discharges to an open drainage ditch approximately 750 feet to the south. The drainage ditch flows south for approximately 250 feet before entering Wolf Creek. From approximately 15 May to 15 November there is no upstream flow in the drainage ditch. The Discharger uses geothermal heat for space heating only so there is no usage or discharge from mid May to mid September. |
