Pond embankments were stable and vegetated. No problems were noted, with the exception of the <br />following: <br />- A gully from the access road between the Area 1 Pit and Pond D has formed from the road to Pond D near the <br />inlet of the Area 1 Pit. Maintenance will be required to repair the down - cutting of the gully. <br />- Although Pond D was low, a small delta has formed at the inlet of the culverts from RDA -3 and RDA -1. <br />Cleanout of this area may be required. <br />- The erosion control measures at the discharge will require maintenance. The silt fence and straw waddles are no <br />longer adequate. The silt fence has been buried and displaced and the waddles are displaced. Maintenance of the <br />BMPs will be required or reinstallation of the BMPs is required.
