The spoils springs will need to meet the termination requirements, like all <br /> perpetual discharges (need to meet the permit limits without treatment). <br /> I hope that helps. <br /> Erin <br /> Erin Scott <br /> Unit Manager <br /> Permits Unit 3 <br /> ' <br /> P 303-692-3506 <br /> 4300 Cherry Creek Drive South, Denver, CO 80246 <br /> erin,scott@state.co.us I www.cotorado.gov/cdphe/wqcd <br /> 7.4 hii„ IE inviiironrneirnt:at II:ZeL ease/Ilnciideint.: 11...:ine- 1.877.518.5608 <br /> On Wed, Dec 13, 2017 at 11:03 AM, Hernandez- DNR, Daniel <daniel,hernandez@state„co„us>wrote: <br /> Howdy Erin. Hope things are going well. <br /> We are in the process of reviewing a partial Phase I II bond release request from Peabody for their Sage Creek coal <br /> mine (what we mean by a "partial' Phase III bond release request is that only a part of the mine is the subject to the <br /> bond release application; should we approve the application, there would still be other parts of the mine that are either <br /> still active or that have yet to achieve Phase III release). The partial Phase III application number is SL4 (the "S" in SL <br /> stands for"surety"; the "L" stands for"release"). <br /> During the bond release inspection, we noted a couple of spoil springs that had not been observed before (photos <br /> attached). These spoil springs exist within the area being requested by Peabody for Phase III release. One spring has <br /> a bit of flow; the other, not so much. The water from the flowing spring traveled about 50 feet before disappearing, the <br /> disappearance likely being the result of some combination of percolation into the soil as well as evaporation.
