To: fir. Peter Hays <br /> Date: Febwary 21, 20" <br /> Pa<-e 27 <br /> Comment 7 <br /> Did the applicant sample for radionuclides that are part of Reg 41 Table I? <br /> Response 7 <br /> We included uranium in the metals analyses, which in our experience is a good indicator <br /> in natural waters for other radiological components. Because there are no nearby, <br /> upgradient sources, uranium is naturally occurring on the Front Range, and LRM's <br /> activities include only mining,we anticipate sampling for uranium metal to be sufficient. <br /> Comment 8 <br /> Nitrate/Nitrite as N was sampled, Appendix B, in some wells but not others, why? <br /> Response 8 <br /> Nitrate/Nitrite as N was not sampled in some wells,due to miscommunication with the lab. <br /> Going forward, all groundwater samples will be tested for Nitrate/Nitrite as N, as well <br /> Nitrate as N and Nitrite as N. Please see updated sampling matrix in Table 2 in the revised <br /> Ground Water Sampling and Analysis Plan(Attachment 16). <br /> Comment 9 <br /> Nitrate, Nitrite, and Total Nitrate + Nitrite are Reg 41 Table 1 values that appear to have <br /> not been sampled in all wells,please comment. <br /> Response 9 <br /> Nitrate/Nitrite as N was not sampled in some wells,due to miscommunication with the lab. <br /> Going forward, all groundwater samples will be tested for Nitrate/Nitrite as N, as well <br /> Nitrate as N and Nitrite as N. Please see updated sampling matrix in Table 2 in the revised <br /> Ground Water Sampling and Analysis Plan(Attachment 16). <br /> Comment 10 <br /> The Division recognizes there will become a point when a reduction in groundwater level <br /> and quality monitoring frequency becomes reasonable. The reduction requests and <br /> approvals will be completed through submittal of a Technical Revision. <br /> Response 10 <br /> Thank you for the clarification. LRM puts forth its intentions in this application to file <br /> such a revision at the appropriate time. We added language to clarify this point in the <br /> revised Groundwater Sampling and Analysis Plan(Attachment 16) <br /> 20220209 1045_DBMS_Adequaey_Review_Response_MASTE <br /> R.docx TELEST© <br />
