100 sq. m. (Note: the above probability adjusted standard was used for each <br />reference area type and the resulting values were weight averaged to determine <br />the applied standard) <br />Since the Phase II bond release area value was greater than the standard, Alternative <br />Test B is passed for the 2009 sampling data. <br />• Alternative Test C, the similarity index between the lifeform species density values <br />for the prescribed lifeforms for the bond release area and the Mean Species density <br />(Area - weighted) in the 5 reference areas is 79 %, exceeding 90% of the standard of <br />67.5°/x. <br />Hence Alternative Test C is passed for the 2009 sampling data. <br />• Alternative Test D, the total number of native species encountered in the first <br />twenty -five samples of the bond release area that constituted an adequate cover <br />sample was 80, substantially greater than the weighted reference area average species <br />density (25.3). <br />The 2009 Phase II sampling results used in the Testing for Revegetation Success for <br />Phase II Bond Release is contained in Attachment E, Revegetation Supporting <br />Documentation. <br />Water Quality — Total Suspended Solids (TSS) Monitoring Results <br />The Colorado Discharge Permit System (CDPS) permit has a TSS limit of 35 mg/1 <br />(monthly average) and a 70 mg/1 daily limit that cannot be exceeded. Water quality <br />statistics have been run for the five (5) ponds that discharge off -site. The statistics were <br />compiled for the previous five (5) year period and show the following results: <br />Pond 006: 11.5 mg/l (average) —21.0 mg/l (maximum) <br />Pond 009: <5.0 mg/l (average) — <5.Omg/1(maximum) <br />Pond 015: 8.0 mg/l (average) — 14.0 mg/l (maximum) <br />Pond 016: 7.8 mg/l (average) —14.0 mg/l (maximum) <br />Pond 017: 10.4 mg/l (average) — 21.0 mg/l (maximum) <br />In addition the background levels for the receiving streams upstream of the confluences <br />are significantly higher than the discharges from the Phase II request area. <br />The monitoring results show that the TSS standard/requirements do not exceed the <br />criteria limits set by the State of Colorado.
