Summary of metal loads from adits and combined mine waste for <br />the Animas Basin above A72 •----•• .....................................................................23 <br />L INTRODIICTION <br />The Animas River Stakeholders Group (ARSG) is a collaborative effort <br />involving a wide range of public and private interests including the Colorado- Water <br />Quality Control Division (WQCD) and the EPA, Region VIII. The group is committed to <br />an interactive, open forum where all interested parties are involved in the design and <br />implementation of watershed improvemects. The mission of this group is to improve <br />water quality and aquatic habitat throughout the Animas Watershed. The primary focus <br />of attention is directed to reducing water quality and habitat impacts created by historical <br />mining practices in the Upper Animas basin, near or above Silverton, Colorado. <br />Activities include monitoring and analyzing water quality data, assessing the impact of <br />COnta*~?in~ms and channel modifications on aquatic life, evaluating the feasibility of <br />cleanup actions and formulating, implementing and assisting with remediation activities <br />The ARSG has no direct authority; however it developed an extensive Use <br />Attainability Analysis used to recommend the establishment of appropriate stream use <br />classifications and standards that are based upon partial remediation of major <br />anthropogenic sources of metals pollution. The UAA also sets remediation objectives <br />that will lead to attainme~ of those classifications and standards within a 20 year period. <br />In addition, the group provides monitoring, characterization, and remediation technical <br />expertise to appropriate land managers, regulatory and enforcement agencies, and private <br />landowners. The ARSG has an established record of obtaining funds and implementing <br />programs that establishes environmental stewardship while improving water quality and <br />aquatic habitat. <br />Through education programs and participation in this collaborative stakeholder <br />process, it is anticipated that renewed community stewardship will achieve cost effective <br />and long term protection of our water resources. <br />This Animas Watershed Plan is based upon the Animas Use Attainability <br />Analysis completed in 2001. Recommendations made for use classifications and numeric <br />stream standards throughout the basin have since been adopted by the WQCC and <br />approved by the EPA The uses and standards were adopted based upon detailed <br />information provided in the UAA as to sources to remediate, associated costs, expected <br />reductions, and the biological potentials of the receiving streams_ A Table of Contacts of <br />the UAA is provided in Appendix A A CDROM copy of the complete documem <br />
