<br />' "New ground water monitoring stations down <br />gradient of the tailings pond area, as required and <br />' approved by t/re MLRD, s/rall be sa»rpled bi- <br />rveekly. " <br />' hems (IJ through (4J in this section should be mnended to occount for this <br />amended language. <br />' RESPONSE: BMR does not agree that (tern (5) at the top of Page 3 is at odds with Item (1) <br />on Page 2. What these two items state is that specific monitoring stations will be <br />sampled on a bi-weekly basis and will also be included in the quArterly sampling <br />t with the other monitoring wells and surface water stations. <br />BMR does agree that surface water monitoring stations RS-5 and RS-6 should be <br />' monitored on a bi-weekly basis, however, BMR does not believe it is necessary <br />to monitor RS-4 on a bi-weekly basis (see Response to Harry Posey's Comment <br />No. 2 above). <br />Likewise, BMR believes that ground water monitoring stations M-2, M-6, M-7, <br />M-8 and M-9 should be monitored bi-weekly; however, BMR Qoes not believe <br />' that monitoring wells M-4 and M-10 should be monitored bi-weekly (see <br />Response to Harry Posey's Comment No. 2 above). <br />' BMR also agrees that additional monitoring wells drat will be installed <br />downgradient of the tailings facility as part of the modifications to the ground <br />' water monitoring plan (Technical Revision 008) will be sampled on a bi-weekly <br />basis. <br />' S. Page 5 + Section 2 (inclusiveJ. BMG should reconsider the propasnl to rinse all <br />sampling equipment widr tap water and provide the Division cviddncc that nc~ top <br />water at San Luis, which is essentially groundwater, has n chemical composition <br />similar enough to that of nc~ processed water and to local surydce water that <br />' concentrations of evaporated salts otr the sampling equipnrenr will not affect/ any <br />of the arra[yses significatrtly. <br />RESPONSE: Sample collection equipment is intially rinsed with tap water and followed with <br />final rinse with deionized water provided by the BMR on-site laboratory. BMR <br />' will revise the protocol document to reflect the actual procedure that is being used <br />for decontamination procedures. <br />' 6.
