Farms Pit (aka Riverview <br />Resources) has been put on hold due to economic conditions. Depletions <br />covered by this SWSP include water lost due to evaporation, dewatering, <br />dust control, and concrete batching. During Spring of 2011 the pit was <br />flooded by the Poudre River due to the high spring runoff conditions. The <br />entire exposed surface area is assessed evaporative losses as this is an <br />unlined pit. The Applicant has filed an augmentation plan in water court <br />(case no 90CW23) and will keep this pit in this SWSP while the <br />augmentation plan is pending. <br />Exposed Ground Water Surface: 68.0 acres <br />Active Dewatering: Yes <br />Status: Mining operations at the F- Street Pit are complete and reclamation <br />is in progress. Depletions covered by this SWSP only include water lost <br />due to evaporation as lagged dewatering and operational depletions are no <br />longer accruing to the river. <br />Exposed Ground Water Surface: 26.2 acres <br />Active Dewatering: No <br />Status: This pit is no longer included in this SWSP. Aggregate sold this <br />mine to Superior Oilfields and are no longer responsible for depletions at <br />this site, including those from past mining operations.
