<br />both the Colorado Department of Health and from Accu-Labs regarding this <br />technique. Use of the ISE for in-house monitoring may be useful, but the Division <br />will not accept data from this technique without verification of the results using <br />another EPA-accepted method. <br />PAGE BY PAGE COMMENTS <br />PAGE COMMENT <br />NO. <br />1 Are there Monitor wells numbered M-3 or M-5? If so, where are they? <br />2 a. Exactly where is the sampling point mentioned in item (2) [top of page]? <br />b. Where are the two off-site wells (item (5), top of page]? <br />3 Item (5) [top of page] does not agree with item (1) [bottom of page 2]. Furthermore, <br />considering that the specific flow path of any leak from the tailings ponds to the Rito <br />Seco is not known, other sampling points need to be established. Considering both <br />these corrections and the need to establish more sampling points, Itlem (5) should <br />read: <br />"(5) Surface water monitoring systems (RS-1, RS-2, and RS-3) should continue to <br />be monitored quarterly. Surface water monitoring stations (RS+4, RS-5, RS-6, <br />and a new station on the Rito Seco, west of the tailings area, and in the flow <br />path of any potential leak from the tailings area) should be sampled bi- <br />weekly. <br />"Ground water monitoring stations (D87-24, M-1, and M-11) should continue <br />to be monitored quarterly. Groundwater monitoring stations (PVI-2, M-4, M-6, <br />M-7, M-8, M-9 and M-10) should be examined bi-weekly, apd sampled if <br />sufficient sample is available. <br />"New ground water monitoring stations down gradient of they tailings pond <br />area, as required and approved by the MLRD, shall be sampled bi-weekly." <br />Items (1) through (4) in this section should be amended to account for this amended <br />language. <br />
