These two ponds collect all surface <br />runoff from disturbed areas except those for which small area exemptions have been granted. <br />Thus there was no impact to surface waters quality from surface runoff. Pond 2 was dry during <br />most of the year (Division inspections). Pond 1 was frequently contained some water, but only <br />has the capacity to retain up to 1.7 acre feet (Exhibit 12-4, PAP). The watershed of both ponds is <br />approximately 0.0006% of the Dry Creek watershed (PAP, page 1, Tab 15). <br />Ground Water (Alluvial) <br />Impacts to alluvial ground water are predicted to be insignificant (Page 7, Tab 15). Monitoring <br />indicates ranges of water quality parameters consistent with historic values (Page 5, pazagraph <br />3.3). There is an appazent impact to alluvial groundwater, but not confirmed due to a lack of <br />information. This items is brought to the attention of the operator. <br />CWQCCR 31 <br />Basic standazds and methodologies for surface water aze defined in Colorado Water Quality <br />Control Commission (CWQCC) Regulation (CWQCCR) 31.
