The rock rip rap placed in the bottom of they SAf ETY•SCIENCE I <br />excavated spillways was sufficient in size and volume to deter erosion. No erosion of t sill Owens <br />embankment cut slopes was observed. The severe scarification and the minimal height c~Lld~se <br />areas was sufficient to minimize erosion potential.

Comprehensive inspections of the pond construction areas were made on a periodic basis <br />from June through October 2005. As an inactive mine, only one inspection was required to be <br />performed. <br />C. No sampling was undertaken. No evidence of discharge from any of the ponds was <br />observed in 2005. <br />C:\sgr\clbsn\stmwrpondsOSp <br />4 <br />Office of Office of Colorado <br />Mined Land Redamarion - Active and Inactive Mines Geological Survey <br />
