Box 316 <br />Pueblo, Colorado 81002 <br />RE: Minor Revision No. 1, Allen Mine <br />File /lC-012-81 <br />David C. Shelton <br />Director <br />n <br />~~~ ~l~ . _ <br />\ 1 :. J :~.: ~.:? <br />A~I~lIAJ~ ~:Fo <br />ARtA.lBnrr ' <br />Dear Mr. Zeeb: <br />• The Division has reviewed your responses to the above revision. This <br />revision has been approved with two stipulations. These stipulations <br />were discussed and agreed to during a telephone conversation with Mr. <br />William Boles of your department. <br />The following stipulations are: <br />1. CF&I should include either Emerald Crownvetch or Latana Cicer <br />Milkvetch at [he rates indicated in Table 16 of the permit application. <br />Stockpiled topsoil looses nitrogen very easily. Including one of these <br />nitrogen fixing fortis in the seed mix will help to maintain the fertility <br />of the soil while it is stockpiled. <br />2. A composite soil sample of the subsoil material to be excavated for the <br />shaft collar must be taken and analyzed for pH, EC, SAR, texture, sodium, <br />calcium, and magnesium. After topsoil has been removed subsoil that is <br />excavated for the shaft collar should be stockpiled in an area where topsoil <br />has been removed. Ten samples should be taken from different locations on <br />the pile and a composite sample made from the ten samples. This sample <br />should be analyzed and results forwarded to the Division within 60 days <br />of stockpiling of the material. If the material is not toxic, as <br />evidenced by the sample results, it can then be spread on the site. If <br />it is found to be toxic or harmful CFI will be required to dispose of the <br />material, probably a[ Che refuse disposal site near the mine office. <br /> <br />S'~ -0 2 <br />~~8 <br />DEPARTMENT OF NgTURAL RESOURCES <br />D.
