No erosional problems were noted on the road. Hydrologic Balance: -The Section 16 Pond was inaccessible due to snow at the time of the inspection. - The wash bay pond (not a NPDES discharge point) contained water approximately two feet below the top of the embankment and was not discharging. This is a total containment pond and discharge into the Work Area Pond triggers BTEX testing (in addition to regular NPDES testing). The pond embankment was well vegetated and appeared to be stable at the time of the inspection. No erosional problems were noted on the pond embankment at the time of the inspection. - The work area pond (NPDES 002A) contained water approximately one foot below the top of the discharge pipe and just to the weep hole on the discharge pipe but was not discharging at the time of the inspection. There was some water in the flume so the pond had discharged fairly recently. The pond embankment was well vegetated and appeared to be stable at the time of the inspection. No erosional problems were noted on the embankment at the time of the inspection. The emergency spillway is an open riprapped channel. The spillway was stable at the time of the inspection. -The Gossard Pond (NPDES 003A) contained water approximately three feet below the riser pipe and was not discharging at the time of the inspection. The pond embankment was well vegetated and appeared to be stable at the time of the inspection. No erosional problems noted on the embankment at the time of the inspection. The emergency spillway is a 12" culvert. -All of the roadside ditches appeared to be clean and functioning as designed at the time of the inspections. No erosional problems, sediment build-up or blow-outs were noted at the time of the inspection. - The West Pit Pond (NPDES 008A) contained water to the bottom of the gated valve (approximately eight feet below the top of the discharge pipe) on the discharge pipe and was not discharging at the time of the inspection. The presettling sump at the inlet of the pond was full. The pond embankment was well vegetated and appeared to be stable at the time of the inspection. No erosional problems noted on the embankment at the time of the inspection. The emergency spillway is an open, trapezoidal riprapped channel. The spillway was stable and well maintained at the time of the inspection. - The East Taylor Pond (NPDES O1 OA) contained water approximately one foot below the weep hole (approximately eight feet below the top of the discharge pipe) and was not discharging at the time of the inspection. The pond embankment was well vegetated and appeared to be stable at the time of the inspection, No erosional problems noted on the embankment at the time of the inspection. The emergency spillway is an open, trapezoidal riprapped channel. The spillway was stable and well maintained at the time of the inspection. Now that pumping in the West Pit has ceased and all of the equipment has been moved from the site, the operator needs to remove the flex-tubing and diffuser from the pond embankment.
