HYDROLOGIC BALANCE -Rule 4.05 Drainage Control 4.05.1, 4.05.2, 4.053; Siltation Structures 4.05.5, 4.05.6; Discharge Structures 4.05.7, 4.05.10; Diversions 4.05.4; Effluent Limits 4.05.2; Ground Water Monitoring 4.05.13; Surface Water Monitoring 4.05.13; Drainage — Acid and Toxic Materials 4.05.8; Impoundments 4.05.6, 4.05.9; Stream Buffer Zones 4.05.18: The sediment pond did not have any standing water in it. The gated valve on the primary discharge pipe was in the closed position. The outlet of the primary discharge pipe and the open channel emergency spillway were clear of debris. The pond's embankment was stable and well grassed. There was considerable vegetation growing at the bottom of the pond. The long collection ditch that leads to the north side of the pond and the very short collection ditch that leads to the south side of the pond had sufficient capacities. The road culvert where the entrance gate used to be was functional, although a little dirt had built up at the culvert entrance. The hillside spring water treatment pond was discharging at about 10 gpm. The discharge water was orange in color but has been found in the past to be in compliance with water quality standards. There appears to be a small leak in the pond's discharge delivery system to the river. The pond discharges through a long underground pipe to a small catchment basin, which empties into a corrugated pipe that leads to the river. The leak may be in the pipe or in the small catchment basin and does not appear to be coming from any spring in the hillside. The leak has resulted in a little ponding in the thick vegetation to the south. The vegetation in this area is very thick so it is difficult to determine the exact problem. By far, most of the discharge is going through the corrugated pipe into the river. The riverside berm was in place and had sufficient height. The caps were on both alluvial wells.
