<br />Notes
<br />1 Percent of excavated material based on historical operations at permit area - Accounting values based on measurements of actual tonnage.
<br />2. Total excavated material of 200000 tons in 2014 and 450000 tons in 2015, distributed per (1).
<br />3. and 4 Projected tons of material washed and not washed based on historical operations at permit area. Actual recorded values to be used in SWSP accounting
<br />5 Equal to 4% of washed material (3) + 2% of material not washed (4).
<br />6. Exposed surface area outside of lined areas
<br />7 Net evaporation based on gross evaporation (NOAA NWS -33) less 70% of average precipitation Set to zero formonths with average mean temperature less than 32 degrees
<br />8 Historical subirngahon credit at site - From previous historical subimgation credit analysis Accounting values based on measurements of actual ice cover.
<br />9, Equal to (6)' (7) + (8)
<br />10. 0 ac -ft In 2014 and 0 ac -ft in 2015 Distributed based on (1), and Included as part of dewatenng (13)
<br />11 Equal to (5) + (9)
<br />12 Equal to unlagged mining depletions (11), lagged back to St Vraln Creek using AWAS program with following aquifer parameters X =2210 ft, W =2262 ft, T =72300 gpd /ft, and S =0 2.
<br />13 Based on 2013 pumping of 337 gpm, on average, recorded at site,
<br />14 Equal to unlagged dewatenng pumping (13), lagged back to St Vrain Creek using AWAS program with following aquifer parameters X =2210 ft, W =2262 ft, T =72300 gpd /ft, and S =0.2
<br />15 Equal to (12) + (13) + (14) + (10), since dust control comes from dewatenng pumping that does not return to the river
<br />Negative values ( -) represent net depletions to river system Positive values ( +) represent net accretions to river system
