Also in the PDF is a table <br />showing you how mu bond calc is organized, comparing DRMS and QB costs, and noting where I defaulted to your <br />numbers. Right now I have 69 tasks so I only included the summary sheet. But if you want to see the individual task <br />sheets I can generate them, otherwise I'll hold off till the end. <br />Current decision date is Friday the 28, which is a State holiday. If you can get me a response early Monday I may get the <br />changes done and a decision issued by Wed. Otherwise please request another 2 week extension. I'm teaching a class <br />Dec 1-5, so I won't have a ton of time to do my normal work that week. <br />-- <br />Amy Yeldell <br />Env ironmental Protection Specialist III <br />Active Mines Program, Grand Junction Field Office <br />12/15/25, 10:50 AM State.co.us Executive Branch Mail - Re: Colony Mine Rec Plan <br />https://mail.google.com/mail/u/0/?ik=0c26d735f5&view=pt&search=all&permthid=thread-f:1848625200177886274%7Cmsg-f:1850419469094953536&…1/2
