Frank Ferris of ERMR accompanied the inspection and represented the Operator. <br />Covid-19 protocols were followed. The site is in final reclamation, and was not active the day of the inspection. <br />The weather was clear and dry, as the region continues to experience drought conditions. <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 />Both Pond No. 1 and Pond No. 2 were dry.
