Page 4 of 6 <br />10. Interim Narrative <br />CWQCC regulation <br />NA <br />It was determined that bed rock <br />Standard for Ground <br />41.5.C.6 <br />groundwater points of compliance <br />Water <br />are unwarranted at the Seneca II <br />mine. Well SFAL72 serves as the <br />Seneca II Mine's Fish Creek Alluvial <br />ground water point of compliance. <br />Ambient values for this site were <br />higher than the Reg. 41 standards <br />for iron, manganese, nitrate, and <br />sulfates. The iron standard was <br />exceeded with values of 5.03 and <br />2.88 mg /1. It appears that the high <br />iron values observed at SFAL72 are <br />not likely the result of discharges <br />at Seneca II due to the iron value <br />levels at Alluvial Well SBAL68. <br />11.

Basic Standards for <br />CWQCC regulations <br />NA <br />The Seneca II Mine did not <br />Ground Water <br />41.4 and 41.5 <br />generate significant amount of <br />leachates in 2011. Both <br />groundwater wells exceeded the <br />manganese standard (0.2 mg /1) in <br />2011. As mentioned in the above <br />item number 8 above, in soils with <br />
