Slormw~ater Manaeemenl Plan 1226/97 <br />• 2.0 COMMON TECHNICAL INFORMATION <br />2.1 Activity Description <br />The 4 areas subject to the SWMP include 3 mining areas and 2 plant areas (See Mine Base <br />Map). The overall purpose of the project is to mine and crush/screen the project's <br />aggregate resources without adding significant amounts of sediment to the 2 streams near <br />the area: Tallahassee Creek and Arkansas River. No mining or plant activities will occur <br />in or adjacent to either body of water. After mining, reclamation activities will focus on <br />stabilization of disturbed areas. <br />2.2 Site Map <br />The Mine Base Map for the Parkdale Project has been derived from a USGS base. Site <br />maps for each of the SWMP sites are in Section 3. <br />2.3 Description of Potential Pollutant Sources <br />Suspended solids in water could come from mining and plant operations. The material <br />would be sand and rock material as it currently exists at the site. <br />2.4 Significant Known Spills or Leaks of Toaic or Hazardous Substances <br />There are no known spills or leaks or toxic or hazardous materials on the property. <br />2.5 Surface Water Flow Direction <br />• Surface water flows toward the Tallahassee Creek north of the Tallahassee Creek and <br />primarily south towards the Arkansas River south of the Tallahassee Creek. <br />2.6 Summary of Sampling Data <br />Sampling data is unavailable. <br />2.7 Description of Sampling Points <br />Water will be sampled from outfalls 001, 002, 003 and 004 when process water and/or <br />stormwater is discharged. <br />2.8 Preventive Maintenance and Inspection Procedures <br />All erosion control measures will be inspected at lease once per week during active <br />operations and following any rainfall of 0.5 inches or greater per 24 hours. All control <br />measures will be maintained in good working order. Any necessary repair or maintenance <br />activities will be initiated within 24 hours of report. Devices will be inspected to ensure <br />that they are securely anchored. Accumulated sediment will be removed when it reaches a <br />depth that could affect performance. <br />The Applicant's on-site representative will be knowledgeable in erosion control measures <br />and be responsible for the inspections, maintenance of the SWMP, the SWMP Log and <br />reports. The on-site representative will be responsible for documenting compliance with <br />specific items in the SWMP. Copies of all incident reports will be sent to the Agile <br />. representative. A comprehensive inspection of all SWMP sites will be made and a report <br />Page 3 <br />
