For recently active mines, photographs of the active mining <br /> phase may be substituted. <br /> c.

Description of BMPs during Remediation Activities: The plan shall describe BMPs that will be <br /> implemented to reduce the potential of remediation activities to contribute pollutants to stormwater <br /> discharges. Activities that shall be addressed include vehicle maintenance, earth moving, material <br /> storage and spill prevention. <br /> e. Procedures for Disposal of Water Stored Within Mine Waste: The permittee must describe how <br /> any water stored within the mine waste will be collected and/or routed to any storage or treatment <br /> facilities. No discharge of this water shall be made to waters of the state,unless separate permit <br /> coverage is obtained. <br /> f. Description of Permanent BMPs,Final Site Stabilization,and Ultimate Land Use: The plan shall <br /> include a description of the specific permanent measures that will be installed or used at the mine- <br /> waste site. The description shall include any of the following if appropriate: specifications for capping <br /> or isolation of the mine waste, method and type of revegetation, and other permanent BMPs.
