The weather was clear and dry, although the summer to date had been unusually wet. The work <br />done in April and May had left the site in good condition, with new vegetation on many of the re -seeded areas. <br />EXCESS SPOIL and DEVELOPMENT WASTE — Rule 4.09 <br />Placement; Drainage Control; Surface Stabilization: <br />Fills 7, 8 and 9 were stable and well vegetated. <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 />All ponds were inspected. Embankments and spillways were in good condition. Pond 8 was discharging at <br />a trickle; the other ponds were holding water but below the discharge level. Several of the flume boxes will need <br />to be cleaned in the near future. A small amount of water had ponded next to the road above the shrub plot, above <br />the inlet to culvert C5. <br />REVEGETATION — Rule 4.15 <br />Vegetative Cover; Timing: <br />The vegetation around the site appeared to be green and healthy. Seeds had germinated in the recently <br />seeded areas, with the pond cleanings area particularly verdant. Some of the new vegetation appeared to be crop <br />wheat which may have volunteered, or have been included in the seed mix as a stabilization species; in either case <br />it was effectively stabilizing the seeded slopes and would not represent a problem unless it was persistent or <br />dominant 3 years after seeding (so, 2018). <br />Arcadis were scheduled to undertake some vegetation sampling in the first week of August, with their <br />attention to be focused on the drainages to ponds 9a and 9b, and the area above pond 5. <br />Number of Partial Inspection this Fiscal Year: 1 <br />Number of Complete Inspections this Fiscal Year: 0 <br />Page 2 of 12 <br />
