• °~ Before the environmental assessment, BLM's concerns included: the rationale for the proposed 3- <br />yearhaul road construction schedule; the location of access routes to sedimentation ponds; concern <br />that the Interburden Disposal Area (IDA) could be unstable and prone to movement during large <br />storm events; the need for a complete cultural inventory; the need to evaluate visual impacts; and <br />a concern that the bond calculations be performed in accordance with the most recent regulations. <br />All ofthese concerns were addressed or ameliorated by operational changes before the amended plan <br />of operations was submitted, by changes in the amended plan of operations or by analysis in the <br />environmental assessment. The COAs listed below contain some further requirements that will <br />address BLM concerns. <br />MITIGATION MEASURES: The amended plan of operations is approved with four conditions <br />of approval (COA). <br />(I) Cultural Resources -American Gypsum shall abide by the cultural Education/Discovery <br />Stipulation (Attachment 1). <br />(2) Wildlife -American Gypsum will work with BLM resource specialists to develop a seed <br />mixture including shrub species for use on BLM lands. , <br />(3) Reclamation and Soil Stability -American Gypsum will be held to the GSFO reclamation <br />success and monitoring standards (Attachment 2). <br />(4) Recreation - In addition to the berm described in Section 4.14.1 of the EA, BLM requires <br />the placement of a fence that will surround the berm at the top of the new mine area's highwall, and <br />appropriate signs which will alert recreationists to the potential hazard ahead. <br />DATE SIGNED: ~-Z'~" Z(~G Z <br />
