These two ponds collect all surface runoff <br />from disturbed areas except those for which small azea exemptions have been granted. Thus there <br />was no impact to surface waters quality from surface runoff. Pond 2 was dry during most of the <br />year (Division inspections). Pond 1 was frequently nearly full, but only has the capacity to retain <br />up to 1.7 acre feet (Exhibit 12-4, PAP). The watershed of both ponds is approximately 0.0006% <br />of the Dry Creek watershed (PAP, page 1, Tab 15). <br />Page 4 of 5 pages, 2004 AHR Review, November 9, 2005 <br />
