It is estimated that there are only 4 <br /> to 8 hrs of activity per week at the site by the claim owner and/or a couple people he allows to also work on the claim. <br /> During their annual inspection of the claim the representative for the BLM had suggested that the Colorado Division of <br /> Reclamation, Mining, and Safety be contacted to see if permitting from them was also required.This was done and the <br /> CDRMS requested we complete a Limited Impact Operations 110(1)Reclamation Permit Application Package. <br /> One of the requirements for the CDRMS 110(1)application is to also contact other agencies such as the CDPHE Water <br /> Quality Division to determine if there are additional requirements. <br /> Can you please advise if there would be any requirements from the CDPHE for the operation as described above (panning, <br /> sluicing, and highbanking adjacent to the Arkansas River).Additional information is available upon request and/or I can be <br /> contacted at the numbers listed below. <br /> Thank You, <br /> Cary"Joe"Lovett, PE <br /> Engineering Manager, Portland Plant <br /> LafargeHolcim <br /> 3500 State Highway 120 <br /> Florence, CO.82116 <br /> Phone 719-288-1448 <br /> Cell 719-285-5518 <br /> joe.lovett@lafargeholcim.com <br /> https:Hmail.google.com/mail/u/0/?ui=2&ik=3cf01277f9&jsver=MC—nFCARLo.en.&cbl=gmail—fe-180610.15_p2&view--pt&msg=163fb6471 b901984&ds... 1/1 <br />
