square feet of such impacted area. Once broadcasted, a light spray of water shall be applied over the same. This will sufficiently neutralize any trace, potentially acid forming material left behind. • The Affected Area is 1.208 acres, with a waste rock impacted zone surface area of 14,800 sq. ft. (0.33 acres). The average grade of the site is 8.5H : 1 V. d. Description of BMPs during Remediation Activities: See Item #4 Stormwater Management Controls above for a detailed description. In this instance the "mining" activity IS the "remediation" activity. e. Procedures for Disposal of Water Stored Within Mine Waste: There is NO water within the pre- existing waste rock dump and NO water discharged from any mine workings at this site. f. Description of Permanent BMPs Final Site Stabilization and Ultimate Land Use: After complete removal of the waste rock dump, permanent reclamation measure shall be applied according to Exhibit D of the CO DRMS permit. • Before applying the newly placed topsoil, a pH treatment utilizing hydrated lime shall be broadcast on any areas previously impacted by the removed waste rock. The lime shall be broadcast at a rate of 50 pounds per 1,000 square feet of such impacted area. Once broadcasted, a light spray of water shall be applied over the same. This will sufficiently neutralize any trace, potentially acid forming material left behind. • Reclaimed or imported topsoil shall be applied over the underlying area now exposed by the removal of the mine waste for a depth of 6 inches. Inorder to improve the soil's water holding capacity, organic matter will need to be added and to the soil. Prior to seeding, the NRCS strongly recommends the application of certified weed free straw (applied at 2 tons per acre) covered with bio-degradable netting or application of wood cellulose hydro mulch with a long-lived tackifrer. Temporary erosion control measures shall be implemented around this area during this activity (le silt fence, straw bales). • If any steep, narrow channels of natural run-off corridors present themselves they shall be rip-rapped on an "as-needed" basis after inspection by Venture Resources' professional engineering staff. In this event, Type L riprap, sized nominally with a median diameter of D50=9 inches, shall be hand placed at a depth of 12-18 inches. Rubble and/or slightly weathered stone sorted on-site from available material that meets this size specification shall be acceptable for use. • This reclamation procedure will be sufficient to return the area to a forestry type meadow. 6. Comprehensive Inspection: Venture Resources has selected Ryan T. McHale, PE as their SWMP Administrator. McHale is a registered CO Professional Engineer and the Company's Vice President overseeing operations. McHale can be contacted at 303-619-6323 or ventureresources6datt.net. McHale will also be responsible for conducting and maintaining the periodic inspections and reports outlined in this SWMP. In the spring and fall of each year, a thorough inspection of all of the stormwater system components delineated in the BMP's section shall be performed. Additionally, material storage and stockpile areas shall be inspected for evidence of any potential pollutants entering the stomnwater system. Erosion and sedimentation controls shall also be inspected. The results of these inspections shall be contained in the Annual Report. 7. Consistency with Other Plans: Venture Resources has developed a very thorough operating and reclamation plan with the Colorado Division of Reclamation, Mining and Safety (DRMS) that can be found within the permit documents the "Robert Fulton Reclamation Project".
