<br /> <br />COM, INC. <br />P. O. BOX 80905 <br />SEATTLE, WA 98108 <br />(206) 932-1800 <br />May 14, 1992 <br />Mr. William York-Feirn <br />MLRD <br />1313 Sherman Street <br />Denver, Co 80203 <br />Dear Bill, <br /> <br />III IIIIII IIIIIII III <br />999 <br />Thank you for sharing the letter from Ms. Dobson with me. I <br />have the following questions/concerns. <br />ORE CONCENTRATES: The test results of the concentrates noted <br />in the letter, don't match the concentrates that we shipped <br />to the smelter. I have attached a copy of the smelter report <br />showing vastly different content. Particularly, notice the <br />Mercury content in our concentrates is nonexistent. I'm not <br />sure what that means. Could the concentrates have been mixed <br />in the lab? Was the sample even from our property? I would <br />be interested in your view. <br />WATER DISCHARGE: It is interesting to note that the <br />permitted levels for discharge seem obviously unattainable, <br />does this require a technical revision to accommodate mill <br />discharge water? At any rate, it is my understanding that <br />the Board views this discharge as an accident, and that <br />proper procedures were implemented 'to insure against this <br />happening again. <br />WATER USE PERMIT: Does the Division have any current <br />information to indicate what industry standards are in <br />groundwater evaluation? <br />TAILINGS POND 6 LINER: The fence going up now seems to <br />satisfy the concerns about this issue. Analysis of our <br />monitoring shows no tailings leaks, all holes were above the <br />freeboard. <br />In spite of the issues raised, I get the feeling that the <br />level of concern that this is a hazardous operation seems <br />low. I hope I am not misreading that statement. <br />The point about the challenge to mining as a traditional <br />industry in Boulder County is of course of significant <br />concern to all of us. <br />
