Wade Wymore of GCC Energy was present for the entire <br />inspection. The weather conditions were partly cloudy and the ground was dry. The temperature was <br />approximately 70F. <br />HYDROLOGIC BALANCE - Rule 4.05 <br />Drainage Control 4.05.1, 4.05.2, 4.05.3; Siltation Structures 4.05.5, 4.05.6; Discharge Structures 4.05.7, 4.05.10; <br />Diversions 4.05.4; Effluent Limits 4.05.2; Ground Water Monitoring 4.05.13; Surface Water Monitoring 4.05.13; <br />Drainage – Acid and Toxic Materials 4.05.8; Impoundments 4.05.6, 4.05.9; Stream Buffer Zones 4.05.18: <br /> King I <br />Reach 1 and 5 were free and clear of obstructions. <br />Reach 7 daylights north of the bathhouse. In this area, sediment has built up and needs to be cleaned (photo 1). <br />The discharge pipes of Reach 2 and 4 were in good condition. <br />West Pond emergency and primary spillways were free of obstructions. <br />East Pond emergency and primary spillways were free of obstructions. The former primary spillway pipe was <br />visible below the soil surface on the west embankment. The former spillway pipe appeared to be at a lower <br />elevation than the emergency spillway, although without accurate measuring equipment, it could not be verified. <br />The former spillway elevation should be verified to be above the emergency spillway or repaired to prevent water <br />flowing through it. <br />The inlet of Reach 9 is obstructed with sediment and needs to be cleaned (photo 2). <br /> <br />King II <br />A bore scope was used to inspect Culvert C-4 to look for possible leaks in the CMP. It was noted in the last <br />inspection report that there may be a leak in the culvert. The bore scope was mounted on a wooden sled and <br />pushed into the western culvert of C-4 A&B from the discharge end. No leaks were noted by the bore scope <br />inspection but a small dent in the CMP and a possible separation at the joint was noted. The distance to the <br />dent/joint was measured and a backhoe was used to dig the soil around the CMP. The outside of the CMP
