<br />'. <br /> <br />~ <br />;..t <br />~" <br />"'-ii <br /> <br />In addition to these BMP's, a model ordinance for erosion control is included <br />in the BMP appendix for this section. This model ordinance is intended to <br />provide guidance to communities which may want to adopt such an ordinance, or <br />update their existing ordinance. <br /> <br />Chapter VI <br />MANAGEMENT PROGRAM FOR NONPOINT SOURCE MINING IMPACTS <br /> <br />The Colorado Nonpoint Assessment Report identifies nearly 1,300 miles of <br />streams as being affected by abandoned/inactive mines. Heavy metals and acids <br />are pollutants of concern from these sites and these can be chronically or <br />acutely toxic to aquatic life. <br /> <br />The objective of the management program for mining is to achieve improvement <br />in water quality and its beneficial uses such as recreation, water supply, and <br />aquatic life. At this time, management practices for control of mine drainage <br />are still experimental in nature. Therefore, a variety of treatment <br />techniques may require demonstration projects to determine performance, <br />maintenance, and economic feasibilities. The demonstration of techniques is <br />intended to lead to criteria which will have wide applicability for use in <br />Colorado watersheds impacted by inactive/abandoned mining. <br /> <br />A list of projects for implementation is included as well as recommendedBMP's <br />which will address the nonpoint source concerns of abandoned/inactive mines. <br /> <br />Page 4 <br />
