Baker Snoqualmie Nat’l Forest 2930 Wetmore Ave. Suite 3A Everett, WA 98201 Dear Sir; The reason I am getting involved with the Monte Cristo Mining Area cleanup is because of its exceptional beauty and some-what intact historical sites. It is very rare to have such a large mining operation from the 1890’s that has not been destroyed by bulldozers, logging or other human activity. A person can still find the mines and how they were constructed, the tramway tower sites, the collector station, concentrator, overflow bunkers, the horse drawn tram and how it connects to the Comet and Golden Cord terminals. Some of the rail spikes in the horse drawn tram ties are still there. This is an incredible part of Washington State and Snohomish County history that can still be seen. It also shows how they operated it. If we keep bulldozing sites up there, all we will really have is a parking lot with trees. I have gone through the Engineering Evaluation/Cost Analysis report dated April 2010 and there are some things I do like: I. The bat gates on tunnels. 2. Cleaning up the tailing piles that are in or very close to the creeks. 3. Water treatment of the mine outflow, especially Mystery #3 and the Justice mines. 4. Securing any open shafts that someone could fall in. I want to state that I have never had any training or schooling in geology or mining. However, my hobby is mining history and how they should have done it by the old books. I am also very ignorant on how all these numbers like 3.4E-03 relate to the danger of arsenic. I also do not know anything about modern toxicology. Most of my facts come from the 1970’s from the US. and Canadian government publications. However, I think the basic concepts should still be accurate. I feel there are several things that show it is questionable if there will be enough success to warrant the cost and destruction of such a rare mining site that the public enjoys going to with this cleanup effort. Here are some examples that make me concerned. P. 33 The table of Summary of Non-carcinogenic Risks, Near Features. There are 7 listings for arsenic in soil and waste rock, surface water and sediment. There are 2 divisions CTE (Central Tendency Exposure) and RME (Reasonable Maximum Exposure) that these results are under. This makes a total of 14 listings for possible arsenic concentrations to exceed “Unacceptable non carcinogenic human health standards. In this table of 14 possibilities, there is only I that exceeds this limit and that is the ingestion of soil and waste rock. , Author: , Accession/Object ID: 2011.4.1, Object Name: Letter, Title: , Description: Letter to Mr. Y.
