The weather was clear, and the ground was snow-covered, especially on north-facing slopes. Vince <br />Massarotti accompanied the inspector in the field. Mr. Massarotti has been very active with maintenance at the <br />Lorencito Canyon site, including (but not limited to) the cleaning of ditches and sumps, road grading, and wattle <br />repair. Ron Thompson assisted with the records check in the office. <br /> <br />EXCESS SPOIL and DEVELOPMENT WASTE Rule 4.09 <br />Placement; Drainage Control; Surface Stabilization: <br />Fills 7, 8, and 9 and the area that would have been Fill 6 were inspected; all were generally in good condition. <br />There were no signs of instability or erosion on the faces. It is recommended that more wattles be added to the <br />east side of Fill 6. <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 />The following ponds were inspected: 5, 6, 7, 8, and 9A. None of them were discharging. Their embankments and <br />spillways were in good condition, with one minor exception: a rill is developing next to the emergency spillway <br />for Pond 6. This should be repaired (possibly with straw bales) to prevent it from getting worse. Pond 7 is still in <br />need of a survey and may need to be cleaned in near future. <br /> <br />Number of Partial Inspection this Fiscal Year: 6 <br />Number of Complete Inspections this Fiscal Year: 2 <br /> <br />29 <br />Page of <br /> <br /> <br />
