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 /> 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 /> No problems were seen with the culverts that were inspected;these included C3, C8 (24" CMP), C9 (24"CMP), <br /> and a 24" CMP above Fill 7. <br /> Number of Partial Inspection this Fiscal Year: 6 <br /> Number of Complete Inspections this Fiscal Year: 2 <br /> Page 2 of 9 <br />
