<br />of 1998. This supports statements that migration of sulfate and manganese is <br />occurring from the West Pit. What is not known is how concentrations of other <br />constituents vary. This information should be presented. <br />.It is our understanding that reclamation of the West Pit and East Pit is currently <br />occurring. The possibility exists that soil used for reclamation purposes is also <br />causing sulfate and manganese pollution problems addressed in the BMRII report. <br />Without continuous monitoring of the Rito Seco fora[ least TSS, TDS, pH, <br />conductivity, sulfate, and manganese, it will not be possible to determine whether the <br />reclamation plan is successful in preventing pollution of the stream. <br />.The BMRI report stresses problems associated with the West Pi[. Are there any similar <br />problems associated with the East Pit? <br />.Does the reclamation plan address how the haul road, leaching ponds and other disturbed <br />lands will be established in vegetation? What kind of monitoring plan is being <br />implemented to ensure the reclantation plan is successful? <br />.It is our understanding that significant erosion is occurring along the haul road. If this is <br />the case, what is being done to stabilize these areas? <br />.I[ is our understanding that wind borne particles are periodically blown off the treatment <br />pond residues. Are these particles causing pollution problems? Also, how will the <br />pond residues be stabilized and vegetation established? <br />.If the enhanced evaporation technique is used to treat water from the Wes[ Pit, will <br />sufficient water rights exist for augmentation of the Rito Seco? <br />Please call if additional information and/or comments aze required. <br />
