COMMENT AND RESPONSE DOCUMENT FOR THE BODO CANYON DISPOSAL SITE, WRANGO, COLORADO LONG-TERM SURVEILLANCE PLAN FOR THE STATE OF COLORADO UMTRA DOCUMENT REVIEW FORM COMMENT Site: Bodo Canyon Disposal I Site. Durango. Colorado Document: Draft Lona-Term Surveillance Plan Reviewer: State of Colorado Date: June 27. 1994Comment: 1, Paae 2-1, Section 2.1 Other histories of the Durango mill site indicate the U.S. Vanadium Corporation (USV)built and operated a uranium after leasing the site from American Smelting andRefining Company (ASARCO) who had operated a lead smelter at that location. This should be confirmed and, if correct, should be clarified in the first paragraph of the site history. The first paragraph seems confused about the chronology of events. It was USV not ASARCO who built and operated the vanadium mill in 1942 and who,from 1943 to the mill's closure in 1946, reprocessed vanadium tailings to provide uranium for the Manhattan Project [hm:leased from ASARCO, who was principle uranium ore buyer for US atomic energy commission (US DOE)].

RESPONSE Page: 2-1By: C. Saumur Date: September 1995 Section 2.1, Site History, has been rewritten to read as follows: "In 1942, U.S. Vanadium Corporation leased the property and constructed a uranium processing mill on the site. This mill operated until 1946, when the mill was shutdown."

[it is commonly known that in the early days lead smelters were used to separate out uranium from parent ores]
