p j7iji?d`I c poroted <br />2. Site 2 <br />Portable meteorological station along the northwestern permit boundary of the Cresson Project (--850' <br />south of the south end of Silver Street in Cripple Creek). This location is approximately 38 degrees <br />44'42.00" and 105 degrees 10'05.95" W at approximately 9600" elevation. Quest 2900 Sound <br />Analyzer, s/n CDE020009 <br />June 12 to June 26, 2007 - Run Time: 336 hours <br />June 26 to July 5, 2007 - Run Time: 217 hours <br />July 5 to July 12, 2007 - Run Time: 168 hours <br />July 12 to July 23, 2007 - Run Time: 263 hours <br />July 23 to August 7, 2007 - Run Time: 358 hours <br />Total Run Time at Site 2 - 1342 hours <br />3. Site 3 <br />Near the northwestern permit boundary of the Cresson Project along County Road 82 (--1800' <br />northeast of the Molly Kathleen Mine) and 150 ft. north of CR82. This location is approximately 38 <br />degrees 45' 19.35" N and 105 degrees 09' 16.50" W at approximately 10,160' elevation. <br />Quest 2900 Sound Analyzer, s/n CDD070021 <br />June 21 to June 26, 2007 - Run Time: 123 hours <br />June 26 to July 5, 2007 - Instrument Malfunction <br />July 7 to July 12, 2007 - Run Time: 123 hours <br />July 12 to July 23 - Run Time: 261 hours <br />July 23 to August 7, 2007 - Run Time: 360 hours <br />Total Run Time at Site 3 - 867 hours <br />Figures labeled 1 a thru 3f in Appendix A are a graphical presentation of the noise level on an hour by <br />hour average dB(A) for the total time of 3718 hours. A heavy solid line along the middle of each graph's <br />timeline corresponds to the nighttime hours of 7:00pm to the following 7:00am. Each horizontal tic mark <br />corresponds to three hours. The dotted and dashed lines at the bottom of the graphs are the maximum <br />and average wind speed. It can be seen that there is a reasonable degree of correlation between <br />maximum wind speed and higher noise levels keeping in mind that the wind data were that recorded at <br />the Poverty Gulch meteorological station located near Measurement Site 2. Higher levels that do not <br />correlate to wind events are probably caused by thunder or motor vehicles nearby. <br />Rev # EDI Job No. C3616 <br />Page 8 of 17 <br />3925 S.
