<br />The required fee of $4112 (16 sites x $257fsite renewal fee) has been submitted.
<br />The Applicant previously included the Lawrence Wash Plant, Fulton Lakes and Larson Pit in
<br />this plan approval. Those pits have been removed from this plan for the following reasons:
<br />Lawrence Wash Plant - In 2006 the lake was backfilled and Aggregate fully
<br />augmented all remaining stream depletions resulting from previous mining activities.
<br />Thus, there is no longer any out-of-priority depletions resulting from operations at
<br />the site.
<br />Fulton Lakes -Aggregate has completed mining and reclamation at this site and
<br />has conveyed ownership of the site to the City of Thornton. Reclamation of the site
<br />included completion of a slurry wall liner. According to Aggregate all lagged stream
<br />depletions resulting from previous mining activities have been replaced, therefore,
<br />there is no longer any out-of-priority depletions accruing to the river as a result of
<br />past operations at the ske.
<br />Larson Pit -The landowners have assumed augmentation responsibilities for this
<br />site and have submitted a separate renewal request for the site. That SWSP
<br />request was approved on May 30, 2007.
<br />Regular mining operations are currently occurring at the East 8" Street Pit, WW Farms Pit,
<br />Distel Pit, Hazeltine Pit, Brighton Pit, Tucson Pit, and Wattenberg Pit. Depletions resulting from
<br />evaporation and mining operations at the sites are replaced under this plan.
<br />Mining at the Tucson South Pit and Tull Pit will not begin until after 2007.
<br />Aggregate has completed mining at the F-Street Pit and is continuing with reclamation
<br />activities.
<br />Mining and reclamation of the Teti Pit is complete leaving exposed ground water requiring a
<br />permanent plan for augmentation. Aggregate is currently working towards filing an application for
<br />a plan of augmentation with the water court.
