Mr. Michael L. Brown <br />April 17, 1980 <br />• Page Two <br /> (ii) Develop a qualitative discussion of the <br /> exposed surfer area on the waste dump following <br /> reclamation, crnrering hydrologic obstruction, <br /> including precipi <br />~ation lost to evaporation, <br />See Sections 5.2.7 ; <br />interception, depression storage, and infiltration. <br />and 2.2.3 E <br />B. Infiltration (Runoff) Study <br /> (i) Following a summer thunderstorm which <br /> generates runoff in Ralston Creek, and which <br /> is of sufficient intensity to cover the waste <br /> dump, Cotter will collect water samples from <br /> Ralston Creek at a point upstream from the <br /> NPDES discharge point #001, but downstream <br /> from the waste dump, and at a point upstream <br /> from the waste dump. The samples will be <br />See Section 5 <br />2 <br />7 collected on a daily basis for approximately <br />. <br />. five (5) days (if this is supported by the in- <br /> filtration rate study) or until flow ceases in <br /> Ralston Creek. Samples will be analyzed to <br /> determine the concentrations of Ra-226 and <br /> <br />• uranium, total and soluble. <br />See Sec. 2.2 2. The amended license application will contain facts with respect <br />to previous operation of the ore sorter plant. <br />See Sec. 5.1 3. The amended license application will contain supplemental <br />facts concer ning the functions of the crew which operates the are sorter. <br />See Sec. 5.2 4. The amended application will establish an environmental moni- <br />toring program which includes: <br />A. Particulate sampling at two locations indicated in the <br />original license application utilizing hi-vol s,implers. <br />The parameters will be mass loading and radionu~;lides. <br />B. Radon monitoring at the two hi-vol locations an~i at one <br />perimeter background station, utilizing passive environ- <br />mental radon monitors. <br />C. Monthly water sampling above and below the mine waste <br />and sorter reject storage area, with analyses f~~r <br />Ra-226 and uranium, both total and soluble. <br />D. Semi-annual soil and vegetation samples taken a': the <br />water sample locations identified in C. above, tiaith <br />analyses to be performed for radium. Both washed and <br />unwashed samples shall be subjected to analysis. <br />n <br />U <br />
