j <br />• <br />Michelle R. Rebmann -2- February 2, 1995 <br />On pages two (2) and three i 3) of your letter you state that waste rock on site contains levels <br />of radium similar to or is likely no greater than the naturally-occurring levels present in <br />outcrops in the area. Provide data to substantiate this claim. <br />On page three (3) of your leuxer you state minor seepage of water is fast encountered at <br />approximately the 500-foot l~;vel, and no pumping is required to keep the mine dry. If you <br />can substantiate this information it will help evaluate any potential impact to groundwater. <br />On page four (4) of your letter you state the waste rock which exists on site poses no threat <br />to human health, property, or the environment. Provide documentation as to concentrations <br />(range) of radioactivity, etc. at the site. In addition, provide adequate data showing the <br />EPA's de£mition of toxic levels and the standards other state agencies have set for your <br />operation. <br />If you have any questions give me a call. <br />Sincerely, <br />~gJ <br />ames Dillie <br />Environmental Protection Specialist <br />M:\OSS\~mm\ReLmann.jd <br />
