Venture Resources, Inc. wishes to assert again that a Colorado Discharge Permit is not required <br /> because there will be no process water discharge to surface waters. <br /> 6.4.21(11)(c) <br /> The attached water quality data was collected and analyzed by the US EPA. The DRMS should <br /> feel confident that the analytical detection limits are acceptable. (Please see Attachment VI) <br /> 6.4.21(12) <br /> No monitoring stations shall be necessary. The pre-existing waste rock is being removed <br /> completely. <br /> 6.4.21(13)(a) <br /> The average pan evaporation rate exceeds the average precipitation rates in this vicinity(refer to <br /> the corresponding climatic data attached) when considering long term water balance. <br /> 6.4.21(13)(b)(i) <br /> Monthly precipitation totals for this region have been collected, as reported by NOAA, for: <br /> • Georgetown, Clear Creek County, CO for a period of 1948—present <br /> • Idaho Springs, Clear Creek County, CO for a period of 1948— 1974 <br /> This data is attached. <br /> 6.4.21(13)(b)(ii) <br /> Average wind speed and prevailing direction have been collected for Boulder/Jeffco Airport . . . <br /> the closest station. This data is attached. <br /> 6.4.21(13)(b)(iii) <br /> Monthly temperature data for this region has been collected, as reported by NOAA, for Evergreen, <br /> Jefferson/Clear Creek County, CO for a period of 1971-2000. This data is attached within the <br /> Appendix of this Exhibit U. <br /> 6.4.21(13)(b)(iv) <br /> The pan evaporation rate for the area(as reported by the Western Regional Climate Center)ranges <br /> between 35.5 - 40.5 inches annually. This data is attached. <br /> 6.4.21(14)(a-e) <br /> The site is completely composed of crystalline Precambrian rocks, i.e. gneisses and schists, and <br /> tertiary intrusive rocks such as quartz monzonites overlain by 0-24" of unconsolidated material. <br /> Base geologic information can be found above in 6.4.21(8)(c), an excerpt from USGS Professional <br /> 73 <br />
