Industrial Discharge Permit Inspection Form <br />Page 3 <br />7. Describe the wastewater treatment processes. <br />The wastewater is collected and allowed to settle in sedimentation pond E, <br />which has a maeimum holding capacity of 713,600 gal. No other treatment <br />is provided. <br />8. Evaluate the treatment facility. Include in this evaluation a discussion <br />of any operation and maintenance problems. <br />Treatment system appears adequate. The effluent is meeting the permit <br />limits. No problems noted. <br />9. How are solid wastes disposed of? <br />The sludge from the pond is dredged as needed (about every seven years) <br />and applied to the spoils piles. <br />10. How are hazardous wastes disposed of? <br />NA - none generated. <br />11. Are the facility conditions properly reflected by the permit'? Yes{t) <br />No( ) If no, identify the differences. <br />Is there a need for extra permit conditions? <br />No. <br />12. Describe the physical condition of each discharge point. Is it <br />discharging'? If so, at what flow? <br />No discharge. <br />13. Is the permittee maintaining records as required in the permit? <br />Yes. <br />14. Evaluate the potential for grou.^.dwater impact. <br />The pond is unlined. With the new impoundment regulations (Regulations <br />for the State Discharge Permit System, 6.15), Mined Iand Reclamation <br />Division will need to evaluate the system for groundwater impacts. <br />However, given the relative lack of pollutant loading to the pond, no <br />groundwater impact is anticipated. <br />15. Additional Comments: <br />NA <br />Include a site sketch of the facility and treatment system. If the permit <br />has an accurate and detailed sketch, simply refer to the permit. <br />SKETCH <br />See attached <br />
