.~ s May 27, 2004 Twin Pines Mine Bond forfeiture site administered by the Colorado Division of Minerals and Geology (DMG) Revoked Permit No. C-83-058 EY 04 Special Focus Evaluation May 25, 2004, field evaluation on site Participants: Tim Stark, DMG Kent Gorham, DMG Henry Austin, Office of Surface Mining (OSM) The participants evaluated the Twin Pines (TP) bond forfeiture site for off site impacts as outlined in the DMG / OSM EY 2004 Performance Agreement. This same off site impacts analysis of Colorado DMG's 13-14 bond forfeiture /permit revocation sites was conducted by the joint DMG / OSM Oversight Team during Evaluation Year 2000 (EY 2000). Weather conditions were overcast and windy, ground conditions were very dry on all areas inspected. Prior to the inspection we reviewed documents including the following: EY 1999 Colorado Bond Forfeiture Sites, a DMG listing of all bond forfeiture sites, their respective histories, and current disposition; the OSM December 2000 Annual Evaluation Summary Report, that documents the findings of the EY 2000 special focus evaluations of these same bond forfeiture sites; and the EY 2004 Performance Agreement write up describing the off site impact analysis /evaluation to be conducted over the next two evaluation years (to end June 30, 2005) on Colorado's 14 bond forfeiture / or permit revocation sites (13 bond forfeitures & 1 permit revocation w/o bond forfeiture-a bank completed the reclamation at that permit revocation site). The EY 2000 evaluation findings for this topic listed 3 minor off site impacts, primarily from sediment leaving the permit area, from 3 of the 14 bond forfeiture sites in Colorado. There are no perennial streams receiving direct flow from the disturbed areas at TP. Reclamation at the TP site was completed by the permittee in 1995 prior to bond forfeiture of $22, 600.00 in 1996. This EY 2004 evaluation also finds the site in essentially the same condition as in EY 2000. The site is stable, well vegetated, and not contributine to any off site impacts.
