Table 2
Debeque Gravel Pit
Year -Three Active Mining Evaporative Depletions
Phase 1 Groundwater Exposed 0.78 acres
Gross Evaporation 47 inches (from NOAA Technical Report NWS 33)
Precipitation Station Palisade
Notes:
1) From SEO's Guidelines (2128/95) for sites with elevation less than 6,500 ft.
2) Annual value from NOAA Technical Report NWS 33
3) Average annual precipitation data from NOAA recording station at Palisade.
4) Equals Column (3) x 0.70
5) Column (2) - Column (4)
6) Column (5) / 12
7) Column (6) x number of exposed groundwater surface acres in Phase 1.
8) Average Monthly Temperature at Palisade Weather Station from Western Regional Climate Center over period of record from 1911 to 2012.
9) If Column (8) is less than 32 °F then evaporation is zero, otherwise Column (7).
